I think all new builds should require solar roofing of this kind. Economies of scale would drop the price and considering how long buildings last, they'd pay for themselves many times over in the course of their lifetime.
@Scratchy Ballzack That can be a way for supporting green transition from the government. They should pay the price difference between regular tiles and solar tiles as subsidy when you are installing new roof or renovating old one.
@Scratchy Ballzack a fair point, I can't speak to American prices but in the UK all new build prices contain a very decent margin for the builder. Housing is ridiculously overpriced here too, my argument is that the free market has had plenty of time to do the right thing though.
As a hang glider pilot, I often find myself looking down on acres of roof space and wondered why new builds couldn't be legislated to have some kind of solar. I know it's not as straight forward as that but these panels seem like a great idea and get my vote.
LIKE if you'd like these solar tiles on your house & SHARE if you think all buildings should generate their own power! Full description below... Yes, it's a roof, but it's no ordinary roof. This roof that Robert has come to see is made up from 900 solar tiles! These tiles deliver all the benefits of solar, but without the aesthetic compromise of huge panels added onto your roof that require systems and structures to manage the weight and connections. Surely all buildings should have solar?

How well does it resist to hail the size of an orange? Regarding Tesla solar roof, nothing done in Europe can't be solved by their engineers I would say. Some cases may be specific but you can have a non solar tile where you need to cut them. That's just something to plan when doing the quote.
@@JeremyHamaoui I've seen better solar tiles than both invisible solar and Tesla. Solecco (Si, recycled plastic, tempered polycarbonate), so super lightweight no need for Aluminium, concrete or glass. Much lower carbon footprint. Hailproof too.
@@robinjones5169 did you see the Solar roof v3 too? I've no expertise whatsoever in that field but confident Tesla can manage especially as it's a complete environment. Also they likely have an advantage on the software front. Thanks for your reply.

In the 70’s they had solar or just ambient light powered calculators. I’m wondering when solar power will be incorporated into clothing because they already have battery powered clothes
That's great! The other thing I'd like to see is solar power installations on parking lots. They could shade the cars, generate power, and divert rain water before it washes through all the grease and oil left behind by vehicles. In the States we have car parks that seem to go on past the horizon, all completely exposed to the Sun. Might as well get something out of it!
This has been done in a few places. The problem is it's virtue signalling & like all such things really, there are easier ways. The supports get driven into and damaged, maintenance is a pain, panels can be accessed/damaged/stolen. Far easier/cheaper to just put the solar in secure compound in some waste ground.
@@kennethschultz6465 currently our in-roof (Exasun) PV is producing 1.65 kW as we speak on a cloudy day. Already seen 2.5 kW and waiting for a good day to see it finally reach it's peak output of 3 kW (it's on for two weeks now). So they can produce power! Probably a bit less, but it looks a lot better so there's that.
Let me understand the proposition here. You are going to let these guys take a solid concrete tile and put a sizable hole in the middle of it and seal it with some glue and attach a plastic panel to it to sit out in the sun for decades? The panel has 1/3 the longevity of a solid tile (not sure the longevity of as tile with a hole in it). When the panel fails, you check all your panels and connections. You finally find the one that failed and you want to replace it... Just think it through. Maybe having panels attached on the outside is not that ugly after all?
Whether this system, Tesla solar roof or something else ought to be made more of a standard. I did back of the envelope calculation which says about 52m² on every household would give enough power for the whole country. And I am talking giving power to factories and such. The 52m² would cover more than the energy needs of the household itself. Households only consume about 30% of the power in a western country. Obviously there are complicating factors here in that the power will not be delivered exactly when you need it. But it does give a sense of just how much potential there is in covering every roof. And 52m² is a pretty modest area. I would think a normal house roof is at least 80-100m². But imagine having a house with 100m² solar panels. It will produce 75.00 kWh on average per day. That can charge up a typical Tesla car battery. However your average western household only needs about 10 kWh per day. So you actually got lots of power you can sell to the grid and make money. With the big Tesla car battery you can store this power and just sell it when there is demand to make a pretty penny. And the neat thing about solar is that you can in principle expand as you got money. You don't need to build 100m², you could build smaller. Then make money off that for some years and later expand. With the Tesla million miles battery and bidirectional charging we are going to see some crazy no opportunities for people to have energy independence and actually make money from their home house selling power.
it also will prevent the roof from drying out properly. look underneath most roof systems that have had solar on them for a long time (aside from tile) and they are normally worn down prematurely. the sun is both the enemy & the friend of most roofs
@@BEATmyguest31 This is why a double-layer roof is actually a good thing. You have the lower portion of the roof fully sealed, insulated and drained. Between the two layers is a drainage plain and keeps the top deck cooler, extending the life of the roof itself.
Fantastic Robert! It’s Chris’s slate I’ve been looking at for our North Devon project I mentioned in our discussion earlier in the week about wind turbines and tidal. It’s a shame he didn’t have the slate to show off too but they are lighter and do exactly the same job. This is exactly what the government should be supporting. Soooo much potential out there. Great to see them going on a roof, thank you! 👍👍👍👍
@@MrGonzonator If you have a listed building with a slate roof or live in certain areas where slate roofs are mandated so they match other properties in the area then you don't get a choice.
@@MrGonzonator In these cases as James referred too, over-roof solar panels would not be permitted either. At least not on a roof that can be seen by anyone or from anywhere.
I stumbled across your channel a few months ago, and it was bothering me wher I'd seen your face, then it came to me. Scrapheap Challenge.. CH4.. Great programme. Now here's the sinic in me, the big Big house builders should be made to do this, by law. Make every single new home self sufficient, not just power/heating, everything. Water, sewage everything. We have a farm, and spent £80,000 on solar set up, And not jut solar, wind power too. And on top of that We collect all the rain water, filter it, clean it, etc etc,, we have a bacteria septic waste system, never needs emptying, looks after its self. Yes, it costs money, but in the 5 years we've had it up+running it has now paid fit it's self.. We are almost now completely self sufficient. Even food now we grown ourselves, This is the future.
in austria you get incentives when building a new house and meeting some certain standards/requirements. eletric solar on the roof should be part of these requirements.
@@kona6812 I realised after I wrote that however the operative word here is 'junior'. Unless you can somehow spin green policies as also being anti-immigration you are not likely to get any traction with the OVP.
We have those incentives in America too. For anything solar, energy saving, tankless water heaters, whole home generators, impact windows & doors, smart home tech, etc.
This won't work in the US on most existing residential buildings. Most existing US residential structures are engineered to support an asphalt shingle roof, which is much lighter per square-foot than these tiles which weight 10 pounds a piece. It would work on new construction where the building is designed to take the extra weight, but it would not be possible to retrofit these kinds of roof tiles to most existing US residential buildings.
It is easy to get excited by new technologies and applictions but I so think that this could be a real game changer on new builds or even with complete new roofs as it would attract far less negativity from planners, especially in more sensitive areas.
I think new homes should be regulated to include renewable energy generation, water recovery (for gardens/toilets) and also higher construction standards to ensure that new homes are much more durable than the current batch of "disposable" homes that are currently thrown up.
What we currently see fires occuring in PV installions, built in roofs. The failures are generally caused by faulty connectors of the PV installation in combination with the built-in feature. When we look at this concept we see a lot of connections which can fail. The failure mode of the DC currents is that you get arcing and heating up of the connection, resulting in fires.
Solar is the most "no brainer" - clean power IMHO. Properties of all kinds have lots of roof space + car parks (for e.g.) offer giant surface areas. And as other people have commented, the right incentives and economies of scale will make it a ton cheaper in a short amount of time! I love these solar tiles - let it be the first of many!
This absolutely needed in my opinion as we redo or build new roofs, what a better way to reduce ones footprint, be part of the power generation, power our cars, reduce or eliminate fossil fuels, paired with batteries for storage , there many more option on house batteries today. Great content!
Read ages ago about a block of flats in Brooklyn that wired in their own, off grid solar roof, paid for by the community for the community. With the pandemic and all, with communities focussing on the benefits of Local, perhaps some funding from somewhere would be nice as an incentive. Great content, Fully Charged!
Given that most of the electrical power currently generated is lost during transmission, the closer we can generate the power to where it is consumed, the better.
What is the matter with governments, are they all asleep, they should be proactive with technology dragging everyone to have the latest, environment saving, money saving, devices. I am buying a new home in Monmouth, it is a tired 1966 bungalow with a south facing roof. The house is badly insulated & a new roof may be needed. We need to be encouraged to bring property up to date. We need a Green Government Guru to advise us, it would be so useful, instead we have to weed out what is best all by ourselves. I am older & just want to get on with it all without delay. These solar tiles look to be a very good idea, I must investigate. Fully Charged is one of my favourite sites, thanks so much for all your valuable advice Robert, you are such a special man, all best to you!
Spain has hot water solar tanks on the roofs, and it does have solar farms but wind turbines seem to be the majority of power by other means 21% of used electric in 2019.
I'm very happy with my 20 Norwegian designed REC PV panels and ABB inverter. They generate 8 .megawatts per annum . I have paid only $60 for electricity since this Solarhart system was installed 30 months ago. Payback on the system is 42 months. It was the best system for me. Tesla roofs are for people who dont have to care about money.
This to me is like hybrid cars, retrofitting new tech on to old tech, what about the environmental cost of the concrete roof tiles? It would surely be better to stop using century old roofing systems and use modern light weight roofs that require less timber to support them. Also the added cost of this system is crazy!! I believe we need to design and build with solar in mind, large flat rectangular roofs made with metal insulated panels with solar on top. The air gap helps cool the panels and increases efficiency, holding on to tradition will only hold us back! For me this system is for those with more money than sense, we need affordable and sustainable solutions so that everyone can benefit. Also what about the time to install those panels on the tiles and cutting the hole in them? how much does that cost?
Part of a roofs stability is it's mass, but agreed concrete isn't the most environmentally friendly material, I've often thought there must be a better way. Idk what recycled materials would be suitable though given it must be fireproof, insulating, UV stable etc. USA style shingles are garbage, flat roofs are worse, get back to mining slate in a more sustainable way?? Also, yes £30 a tile is a ripoff!
Killua Zoldyck Flat roofs are the worst for solar, they need to be angled towards the sun. Panels on a flat roof would need to be mounted on an angled frame, so you might as well just build the roof with the appropriate slope. Insurance companies hate flat roofs for a reason- they are notorious for leaks. I agree about concrete roof tiles- personally I think traditional slate is still a good choice- it's relatively low carbon, it lasts well over a century, and top quality slates can be reclaimed and reused. In fact, good reclaimed welsh slate tiles reclaimed from old buildings are more in demand and hence more expensive than brand new ones!
@DrgnFlys Concrete roof tiles with holes probably won't last 100 years. Solar panels certainly won't last 100 years. How do you replace these in 20 years when they start failing? Do you keep the concrete tile and just replace the PV module? In 20 years this company will be long gone and you are stuck with a roof full of holes and no power. Bad idea!
@@spencerwilton5831 I never said flat roofs, i have installed enough solar to know that LOL, I'm talking about insulated roof panels like we use on commercial buildings here, but they use on houses in other countries. Much lighter, less framing as they are themselves structural. Easy to install and easy to put solar panels on.

Great idea for a listed buildings where solar would otherwise not be possible. Until the price comes down they're still going to be far too expensive for most though. How are the solar cells glued to the tiles? and what's the long-term duration of that glue like? If the glue fails you have tiles with holes in the middle all over your roof. I think I'd at least like to have seen the holes at the back sealed around the edge with silicone sealant or something like that.
@@chrishall409 Thanks Chris. I take it more glue is applied than can be seen on the cell used as an example at 2:00? (as that doesn't seem to be particularly good coverage) Would have been nice if Robert had covered some of this in the video as it seems most of the questions here are asking about stuff like this. Great to see you're clearing things up though.
Unfortunately in the "Comparision with Solar Panels" two, imho, major disadvantages were left untouched: 1) no cooling for the panels, actually they are heated up by the tiles - which means a great loss in efficency and also in longevity 2) in electrical installations the connectors are usualy (in long term) the most probable point of failure - and here we have a lot of them. And we are talking of a lifespan for a roof of more then 20-25 years... It's for sure better then no solar at all - but for the sake of transparency this should be also pointed out
I've been saying for the last 10 yrs all new builds should have at least 1kw per bedroom at construction to create a solar network across the country, still not sure about the batteries yet so I think we should sell what's made in the day and buy what's needed at night across countries. Overall there is still a cost but it should be about the same as what we have now, the win is a more stable grid energy and saving the planet.
What do you do during the winter when there isn't as much sun as in summer? You would have about 6 months of black out. You would still need nuclear, coal and gas powered stations.
If you never knew, to give some context, the top of the range system from tesla (2022 solar roof tiles) are on avg 19% efficient, which is not anywere near the 23.8% some top-end panels produce, so realistic you only buy this solar tiles if you want a roof that looks alittle different but doesnt have big panels on it :)
I had this very idea 26 years ago while working on a roof putting anti vandal tiles on.....great idea and about time it became a standard on all new houses
@@darrenit7498 From my calculation a 3.6 kW system would need 240 tiles which is £7400, that's more than you would pay for conventional but the result neater and depending on your POV better.
@@DogsBAwesome That's £7400 for the solar panels AND the roof tiles, the price for a conventional setup doesn't include the cost of the tiles which would be extra on a new-build or re-roof.
An encouraging technology now in the UK. But it’s success will come down to large scale production dropping price significantly for mass adoption. Good luck to them 👍
I have a 17kw solar roof system with 2 Tesla powerall2 batteries. I run my house, and my shop on solar. My average electric bill (after solar credits) is -$410 per month (yes, that is a minus). Haven't paid an electric bill in over 2 years. It's wonderful.
I worked for Mitsubishi in Cirencester, we have 150 solar panels on warehouse roof, was done because we sold PHEV cars, the idea was we were charging cars with self generated electric power, we were ahead of the game
These look really nice, though it sounds like they’re using a single inverter per elevation which I think would suffer under patchy cloud cover vs a panelized system with an inverter for each panel. It really is infuriating isn’t it when you see a field full of solar panels and a bunch of warehouses next door with none. Or if there’s a huge parking lot the same size right next to it. Or a giant housing development with no panels installed! It really is shameful I think to not fit panels to the many convenient spaces left in our built world and steal nature instead.
Abram McCalment we are actually installing a single inverter for the entire project, with separate mppt trackers for each elevation. Each tile has a bypass diode to optimise output individually removing the issue caused by partial shading.
@@Slebonson The problem with Tesla tiles, as Chris explained very well, is that if you have a US style roof with gable ends you are OK, but only if the roof is a whole multiple of tiles long and wide. These solar tiles are identical in appearance to the non-solar, which can be cut to fit. Could you do that 4 aspect roof with Tesla? No.
In 2008 I project managed a new housing estate in Lytham St Anne's, building 111 social housing homes for rent. The scheme included two large blocks of 85 flats in total. All were built to Code for Sustainable Homes Level 4. The apartment blocks had solar interlocking roof tiles, provided by a UK company called Solar Century. The solar tiles were called C21E. Each solar tile was the length of three concrete tiles and interlocked with the concrete tiles and were wired in series. Like Tesla, this video gives the gives impression this manufacturer invented the concept of solar tiling interlocking with traditional roof tiles in 2010. In reality, Solar Century were doing the same, albeit with triple length rather than individual tiles, years before. We used the solar power generated to subsidise the energy used in the communal areas, to reduce service charges for lighting and lifts. From the ground, the solar arrays were virtually invisible. The scheme was loved by the local town planners.
Thanks, I actually started with Edilians solarmax, the predecessor to c21e, and still install today, the tiles are the first actual tile size product, that is not covered with glass
Please do a video about Marley's solar tile, which is the same size of a solar panel but integrates into the roof like a Velux window would so you save on the cost of concrete tiles.
Eight years ago I just couldn't find a supplier for similar products, so I had the large bolt on framework installed. The roof was designed for the extra loadings. One advantage is that the air gap acts as a tropical roof on sunny days, keeping the underlying tiles cooler. It should be illegal to build a none solar PV roof , preferably with a well designed battery system included.
@James Clifford I did actually try to get a price for solar tiles from Solar Century, The salesman couldn't be bothered to reply to my enquiry. He didn't want to bother with a self build customer. So of course I went elsewhere. My house does have Solar PV, Solar Thermal for water and Underfloor heating as reqd. Ground pipe Air supply plus underfloor extract for air supply, (gives fresh air at 16deg in summer for cooling and in winter at 14deg even on the frostiest day. Heat recovery in the ventilation system. ASHPs to supply underfloor heating by freezing the used warm air being expelled . The house has insulated underfloor , 200 mm wall insulation and a SIPS roof. The garage/ hobby room is heated by ASHP, During sunny days the car is solar charged. Our Electricity bill for a 230 sq mtr house is less than for my mother in laws 50 sq mtr semi. even including 15000 miles for the car. Careful design and good choice of materials are worthwhile.
@fullychargedshow The situation is worse than you think... A chap I met was buying a new build just west of Swindon, Not only wouldn't the builders offer ANY sort of PV as an option, the deeds on the house prevented him from installing them for three years.... I assume that if PV was installed the electric company would refuse to connect them to the grid ? Solar PV should be mandatory !
I have 2 questions: 1 how susceptible to leakage are these tiles? From what I can see, these are glued onto the normal concrete tile? What if the glue bond fails? Surely then there’s a hole in the roof, letting in rain?! 2 it appears that these are wired in sequence? If one tiles electronics fail, does that then stop the entire row/roof from working? Or are there backups to ensure this doesn’t happen?
Hi! Sorry, I don't know anything about wiring solar panels, but I think I can answer your other question... Any rain or snow that got under a tile would fall onto the flexible membrane beneath, and run down into the gutter. That's what happens on regular roofs now if gales blow water back up under the tiles. The roof's hard concrete, ceramic, or slate outer covering is really only there to protect the waterproof membrane underneath from gales, storms, hail, ice, and UV damage. It's the soft membrane that makes a roof watertight, not the tiles. :-)
That would be awesome in Australia. Also preferred how they did the underlying roof stronger than the typical method used here and I'd demand they built my tile roof the same as the UK. To get 13+ kW as well on a house would be fantastic.
I would like to thank Mark & Julie from Batley, W. Yorks for the first order as a result of seeing the tiles on this episode. We are to provide the full roof for their new build, which includes 6 kWp of solar tiles, 10 kWhours of battery storage, and all inverters etc for less than £22,000.
You're not settling. Support someone who has worked in the industry for decades and knows how to install roofs. Not some pipe dream company run by teenagers and fresh grads with little experience outside of poached talent.
Tesla tiles are shit, they're workers work in appalling conditions and they are over priced and set on fire. Why in the world do you want one. Daddy Elon isn't going to let you suck him off if you do.
Why would you even want to send your money to a non-UK company if you live in UK? Second, Tesla tiles would have to be shipped across half of the world in their full shape. Sure they are lighter, but still entire roof has to sail across the seas.
At last, this is my bag, as a architectural technologist for the last 30 years.. I think I will be specify these as an option on my new and existing structures I design.
It may be overpriced for one household to have retrofitted. But a big saving when installed during construction- no labour costs for Installing solar panels and framework, no increased engineering costs related to making a roof strong enough to take the weight of panels. Thats a Winner for a construction firm.
But don’t forget, for your £30 you get a roof tile not just a 15 watt solar module. As with all products, small batch hand made products are initially expensive, with volumes and related economies of scale, prices will continue to fall, in 2018 they were £34 each.
Installer: "Its about 30 pounds a tile" Interviewer: "...oh . . .wow" $27,000 just for the tiles on this roof. Not a hater at all - I hope we all have this one day on every roof but there is a reason why we dont at the moment.
That would be $34,500 dollars, not £27,000 pounds going to be a very long time before that becomes viable for your average housebuilder or even self builder
@Bagheera These tiles should weigh about the same as the normal concrete tiles. The hole drilled through the concrete tile should offset the weight of the photovoltaic panels and wiring. I do agree, however, that the price is a bit steep.
The process is still wrong. You don’t NEED a cement tile backing the solar panel. The purpose of the cement tile is to protect the waterproof sheet. If the solar panel can do that alone, you don’t need a heavy, expensive, cement tile. Just make the solar panels a little more robust to protect the waterproof underlayment fabric! Not only that, the cement tiles hold heat! Without them, the solar panels would stay cooler.
Correct - its pointless. Same thing as normal tiled roof and solar panels, except much more expensive and difficult to install. Better concept would be to eliminate the tiles all together and design the roof to integrate purpose designed larger panels..
Mr. Quindazzi, cement tiles are not cheap. Plus they are a unnecessary heat sink. Keeping temperatures Higher, for quicker degradation of solar panels. And less effective electric production.
Tesla solar roof tiles don't go all the way to the edge. If you look carefully at their literature, you'll see standard matching tiles to cover edges, awkward bits & areas where solar doesn't make sense. As far as I'm aware, those tiles are cut to size on-site where necessary. My one query about the fabulous solar tiles featured in today's video is how is the concrete made? Concrete manufacturing being very polluting CO2 wise. What mitigation measures are being used by the tile manufacturers to counter excess emissions? Perhaps advances in concrete manufacturing could be a topic for a future video.
Right. solar tiles have been around a long time (12 years?), but always significantly more expensive. Unless planners mandate them or you _really_ don't want the standard large panels they aren't very interesting and almost everyone picks the standard scheme. You can also get built-in standard panels and gasketed panels where the panels are the roof. France mandates BIPV (or did) so it's a lot more popular there.
Do hope they are fitted with an air gap as black glass gets extremely hot! During hot very sunny days can see that getting into the home even with best insulation.
@@GlenisRetiredNZ At 15W per panel it is a 13.5kW system, which can cost as much when done with panels. In theory the solar roof goes on as one build and would be cheaper than building a roof and then hiring a separate crew to install solar panels. Also, that is a tile roof and while you can put panels on one I have heard that the frames they need to use for it are fugly. Plus, why would you get a tile roof in the first place and then cover it up even if you don't think panels look bad? I don't think installers are incompetent enough to cause leaks these days, but putting the panels on frames that allow wind under them for cooling also means a stiff wind risks pulling up the frame, at which point it might go flying away if it is not nailed to your roof and could rip off your roof if it is. Many installers actually seem to advertise how they set the panels flush with the roof to avoid making them stand out, so I don't know how valid the argument about panels getting better cooling because air gets below them is anyway. TL;DR: It's never going to be cheaper than just solar panels, but if you are building a new roof you can get more solar power on it at same or cheaper price and make it look better than if you added panels.
They use PTFE solar modules, which are bit better version of flexible solar modules, which are actually the worst(average life -3 years). The PTFE solar modules have average life of 5-7 years, in this case , since they have mounted this within a solid roof, the average life can be as much as 10+ years. In comparison, Normal glass solar modules have 25-30 years of warranty. I try to dig information from the link provided and although the company provide 30 years warranty on the actual roof there was no mention of the solar module because they get it from another company called viridiansolar. I went into check their site, but didn't find any warranty information on their PTFE modules. so if it has only 10+ years of average lifetime that would be a significant waste of resource. Anybody please correct me if I am wrong or you find some more information on this.
What is with the heating up of the panels in direct sunlight? As I recall solar panels loose efficiency when their temperature rises and the traditional way of building a solar roof enables the panels to have cooling by fresh air being able to circulate underneath the panels, isn't it? So these roof tiles would have a worse efficiency?
As a guess I'd day having them on a cement tile would help dissipate the gest into the tile somewhat. But that's just a guess. The roof is still black after all and cement can hold heat for a while so not really sure still. Good point though.
I don’t suspect peak temperatures are much higher, largely since I also suspect air cooling benefit under a normal panel is negligible. Now. . . add water cooling and harvest the waste heat to pre-heat hot water and reduce heating load in the winter and you’ll have an extra high performance roof!
It is part of the reason why I am skeptic of this. The other is that it is likely much more serial panels connected in each array which can cause problems for the charge controller. Most likely you will end up with a more expensive multiple charge controller solution if you go with this system than just adding larger panels.
I live in Scotland, hipped roofs can get in the bin. Gables all the waaaaay. A very valid point about that issue that will definitely be faced installing those Tesla tiles around openings/dormers etc.
My only concern with these is that each tile is individually glued on. How will these adhesives cope with 25 years worth of winters with frost creeping in between the layers? If even one is sub-par you have a hole into your roof and your electrical systems, and then you have to rip the whole lot off. At least with the standalone systems the fixings are under the tiles and do not compromise the integrity of the roof itself. Alternatively with the Tesla offering, the tile and panel are one and the same.
This would be my main concern. If you look at 2:13 there isn't even any sealant around the hole at the back. I would at least have liked to see that gap around the junction box potted with epoxy or silicone.
@@DEADB33F exactly my concern. Once you get a roof leak you are going to need to test integrity of a large number of tiles to find the faulty tile. Also flat concrete tiles are fairly rare where I live. How flexible are planners going to be if I change my roman tiles to flat?
It's perfectly easy just to replace one tile without removing the whole roof, probably easier and cheaper than replacing a conventional panel if part of that fails.
Hi Robert, thanks for the Audi story (rant) the other day, I shared the German article with all my car friends. Interesting with the tiles also! It is truly the next generation, instead of bolting strange blue and aluminium things to your house.
Ok, when it comes to costs, and please feel free to correct me on this: from the video, a traditional concrete tile is £1 (making it £10 per square meter). A solar tile is £30 (making it £300 per square meter). Essentially this roof is 30 times more expensive than a traditional roof. The economics work a little bit better if you compare a roof tiled with solar tiles to a normal roof plus panels BUT not by much. I am all in on solar (have panels on my roof) but I’m not sure the economics of these type of solar tiles makes enough sense. Also, version 3 of the Tesla solar tiles just got cheaper. I cannot remember the exact figures right now but I remember them being far more competitively priced compared to traditional roofs. Again, I reserve the right to be completely wrong here and I stand to be corrected.
It would be cheaper and better to get a standing seam metal roof and regular solar panels. You dont screw through the roof to attach the panels as they clamp onto the metal seam. These solar tiles are retarded and driven by rich, vain people who dont want their house to look funny.
The reason you can have a tile that is 30X more expensive but only add 50 percent to the overall cost is that the labour cost makes up such a big part of the cost of any installation.
@@instanoodlesNot just rich vain people but it likely also going to be drive by people who live in conservation areas who aren't allow traditional solar roofs.
Another excellent video Robert - thank you! The only thing I found a bit odd was that the roofing contractor was having to cut a hole in the plain concrete tile to facilitate installation of the electrical component. This adds time, creates waste which adds cost so I wonder why they can't have the tiles made with the hole already formed as part of the casting process? I'm sure that tile manufacturers aren't doing this now because there isn't a big enough demand for them but hopefully this will change. When it does, the cost of having a "solarised" roof will reduce and so become even more of a no-brainer!😁
think the solar tile is assembled in the country but it shipped as the base component to save weight. my main concern is adding multiple new holes to the roof which aren't covered by the title above
Question - if the rows are done in series, what happens when a panel fails and causes the entire set of panels to fail. How hard is it to find the faulty panel and fix it?
I suspect you get the same problem with conventional panels. If it fails open circuit you lose the row, if it fails short circuit you get lower output. i suppose to find the fault you get up there with a voltmeter!
@@rogerbarton497 Good luck with that. The only way to access the wires is by removing panels. Basically you'd end up removing a big chunk of the roof to find a fault.
I was wondering this as well. I wonder if you could access the cabling from behind. I also wondered if these are interchangeable with normal roofing tiles in the event a panel failed (in a way it was letting water in) and the company was no longer around.
@@rogerbarton497 Many panels come with micro inverters now a days. These will often be able to detect if a panel is producing output, and if not, disconnect the panel from the series. This way you never lose a full series of panels.
If government mandated that a minimum of 80% of a roof area of a new build must be consist of solar panels then prices would fall as manufacturers would scale up operations to meet the opportunity. Falling prices would encourage people who live in older properties to use solar tiles when they come to reroof their homes.
Tesla's solution will be much cheaper long term. Labor cost can be significant, so simple and fast installation is important too, not just manufacturing cost.
🤗100% 👍 AND THE SOONER THE BETTER…. I am watching this for the first time today, not knowing 🥹these things existed before and I am wondering 🤔 how many other things are going on in the world 🌍 we don’t know about 🤔💚💚💚
imagine those tiles under 3 feet of snow, just when you need the most energy being produced? also, the cost is 3 to 4 times the cost of any roof in North America and those tiles are not available anywhere other than EU, so no availability of materials, no return on a cost that is 3 to 4 times more than regular and no electricity production during at least 5 months out of the year also the electricity rate in North America is so low that it would take 100 years to just pay for the tiles and no electricity so you still have to pay for it, where is the value?\Why would anyone install a solar roof if they are not living in a very hot country where it is efficient at least most of the time? I have an electric car because I do not drive a lot and electricity is extremely cheap here, I spend 1 pound per charge or 1 pound per week on charging my car for 165km range. 1 pound for a 40 kilowatt of charge per week. why would I pay 30 pounds per tile to produce electricity that cost less than 10 cents per kilowatt?
Apparently Tesla are now working with third party installers in US, and I came across a piece from the head of (I think) Good Faith energy with a picture of his Tesla-cvered roof, and it it has hips, gables the works. So it looks as if they have progressed from simple rectangular sloped roofs
I’ve been talking to Chris over the last 12 months and they have developed a man made slate that looks very much like a natural slate even down to mimicking the cut edge of a natural slate. We are hoping to use them on our build next year all being well. 👍
@Buster Jangle How does having a slate roof make you a Tory? Life long labour voter here, and I dont want to put a cement roof on my house from 1907...
This is one of those "now why hasn't anyone thought of that before" moments. Rather clever. Obviously, more care is needed during installation to avoid damage to the cells, but there's no doubt this is a step forward. It will meet with the approval of many planners too..... The only reservation I'd have would perhaps be the later possibility of damage caused by anyone installing or repairing a TV aerial or Sky dish etc.......
Every house should have this. I have just bought a brand new house and the builders would not offer us solar panels of any description, I was appalled. If I want solar panels I have to have someone come in after we move in and retrofit.
Yes they should especially those big boxes of buildings should have solar and if room windmills it may not totally provide all the of their power needs but every bit they make for their own use is less taken from the grid. There are lots of those big box warehouse going up where I live now and I don't think Solar is part of the planning. California needs to this.
@@killuazoldyck1352 why is it better? Why would adding dynamic stress to the roof be better? Putting "types of stress" on the roof that the roof was never designed for is better? Please give your reasoning?
@@ColinRichardson roofs are designed to handle dynamic stress, a roof acts like a large aerofoil, it is subject to high pressure wind loads and low pressure wind loads depending on the direction of the wind. That guy was clearly selling his product and trying to justify the huge extra cost. How many roofs with traditional solar panels have failed because of dynamic stress? Also the extra materials concerns me, 2 MC4 connectors per 15w instead of 2 MC4 connectors per 250w, plus the little junction boxes. to me that is wasteful, larger panels are far more environmentally friendly and efficient. Fault finding would be a nightmare to, that many panels in series would make it hard to find a fault. To me this product is badly floored, it has been around for a long time and barely anyone has used it because from an engineering point of view it makes no sense, nothing more than a gimmick like hybrid cars.
@@killuazoldyck1352 Sorry, I got 6 words in and already stopped reading, since you obviously read my comment but didn't comprehend it.. Try again.. If you comprehend it the second time around and you comment I'll possibly read it more fully.
The guy that installed my system recently was installing JA 320w solar panels that now cost £100 each. ie. 3w per £1. Or £1.20 including racking. So these are £30 for 30w. That's nearly 3x the price. You also have a lot of cabling. Like Tesla it might be more efficient to have 3 panels in a row for 90w, then you don't need so many connectors. If you get one poorly fitted connector then you lose the lot and it's harder to diagnose. I imagine as there's nothing behind there there should be no fault. But one bite from a squirrel and the lot might go down! At least with solar panels a fault could be diagnosed to the panel and that replaced without undermining the water protection of the roof.
It does seem a lot, but to make a fair comparison you'd need the price of a non-solar tile roof + the price of an installed solar system on top of it. Remember, this isn't just your solar system, it's your entire roof. Still sounds very expensive though....
Dan Franklin What you say is true, but on a new build what’s an extra 5-7 grand over a normal solar setup. It won’t add that much to the mortgage repayment.
Solar tiles and slates have been around in the UK at least since 2010. They just never took off because it was way more expensive per W than over-roof solar panels that were made in the millions. It sure looks better but most people are not too bothered with the look of their roofs once it means spending £ '000's more. There are also some real drawbacks. One is in the case of a module / cell failure it will be problematic to locate the tile that failed (unless they use micro inverters I suppose), replace the faulty module / tile and pray that the wiring is accessible and not buried in insulation. Secondly the air flow he mentioned under over-roof panels is actually a feature and not a bug (sure storms can cause panels to be lifted off but that's not something I have yet come across). The hotter the modules become the more resistance there is to current flow, reducing the efficiency of the modules on them sunny summer days. Over-roof panels have some airflow alleviating this issue to some degree. Solar tiles have no such airflow. They have some thermal mass in form of the concrete tile but whatever that heats up to in the summer is what the solar modules will have to work at. Not trying to be party pooper, it is a good idea / product for the right application. It's not the best thing since the invention of sliced bread though. Peace out. ;-)
He didn’t really understand how Tesla’s tiles work. They have tiles without solar in them that can be cut to match the shape of the roof. I’d be more interested to hear how these compare in terms of cell efficiency, relative cost, and assembly time. I’m also surprised Tesla didn’t have a patent on the solar tile idea.
The idea of bonding solar panels to roof tiles has been around for decades. It was just the cost of the panels holding things back. ....Even if it was previously patented that patent would have run out long ago.
Jean-Pierre White I watched the video. I thought they were only visible because we were looking dead-on at them. I was still thinking there was a film on top that hid them from the ground
In North America most houses use asphalt shingles that need to be replaced every 10 to 15 years, the concrete roofing tiles would be great here except theses a whole industry based on making, repairing and replacing asphalt shingles. Glad when I built my house I put on a steal roof, that now has solar panels on it. These solar tiles would be great here.
that is a good question as well. those thin solar panels usually have a very short lifespan. also they did not talk about for how long the warranty is.
@@ursodermatt8809 Personal side question, you seem to be from Switzerland ...... are you in the solar business? Looking around for products and services in Switzerland ....
A lot of companies don't have solar panels on their roof because even if their were willing to do it their roof is simply nto designed to support the weight of the installation. This is pretty much what happened where i work, the cost of work to make it possible is so high that it stop being efficient in any way.
Yeah concrete tile roofs are scary heavy, I worked on a building site where the design of the roof trusses was wrong, they had a half truss butting up to a full truss at 90 degs, with basically just nails attaching it, when the roofer put the tiles on, the half truss started to slid downwards bending the nails with the weight, we had to jack it up and wedge a half dozen 4x2 under it and ramset them to middle of the lounge floor to stop it collapsing. They had to make this U shaped saddle assemble that hung over the full truss to the supported the half truss, It was a total pain to install and we total screwed up the roof doing it, the roofer was up there for days fixing the mess we made, swearing and tossing broken tiles off the roof.
taznz1 the stuff of nightmares ; I can imagine what that situation was like with tea breaks even having to be postponed . I would never have guessed those tiles weighed over ten pounds from the way they were lobbing them up and handling them though.
Richard Ward-Jackson My aunt lives in a 400 plus year old Cotswold stone house roofed entirely in stone. Some of them are two or more inches thick- the whole roof must weigh a couple of hundred tons- quite scary when your living underneath! Still, it's held up by a forest worth of huge oak beams and has been there for centuries, so I guess it's OK..
It's a great concept, not sure if the developers would swing for it, but if affordable housing could have them, that would be a start. Of course the buck stops with someone, I wonder who that'll be.
Shipping just the solar plate makes sense, but cutting holes in concrete tiles, then forming an intricate loom of wiring seems very tedious & labour/time intensive. As a suggestion, maybe manageably-sized semi-rigid foam sections, which have pre-installed bus-bars embedded, along with waterproof click together electrical connectors. Foam being light & having insulative properties could make the complete install process very efficient & cost-effective.
The question I have about all of these PV systems, and their attached technology like vehicle to home power, is what happens if their is a massive solar flare ? Are these systems protected from EMP events or will you lose your home and auto all at once and be left up the proverbial creek ?
Where on earth did you hear that from? Absolutely nothing will happen. We are protected by the atmosphere from the UV and the bulk of the radiation. The EMP (Geomagnetically induced current) (GIC) even in a major event will only be important for very long conductors, not like those you get in a roof. You won't see large pulses on the domestic mains supply either. This is a distribution problem. OK - so if you have one of the new power walls your lights might still be on afterwards if there is a power cut.
@@mikewillis1592 Absolutely nothing ? That's certainly not the position of industry experts. It's well known there have been massive power outages due to CME as well as the fact that EMP weapons are a real threat to modern society. It's a given solar power inverters will be burned out, lose their fusing, and require repair from a significant CME let alone human use of EMP weapons. Given these facts are not in dispute by anyone in the power industry it's a completely valid question...what happens if your EV is plugged into your home during a significant CME or if some nut uses an EMP.
How long do the panels last (or are expected to last)? Is there a maintenance interval? Scaffolding needed for maintenance (cost etc). A roof covering has anything from a 40 to 100 year life depending on location and material used. Unrelated points - on a wind turbine could the structure and turbine blades be covered in solar materials to further increase efficiency (flexible solar panels on a roll is on the Horizon)? For many years we have heard about energy generated from pressure plates installed in the floor/paving in busy locations (rail stations, shopping centres & busy urban streets)? Does not appear to be a high uptake on this - an update on the latest innovations would be good to see. Keep the content coming. Thanks.

I think all new builds should require solar roofing of this kind. Economies of scale would drop the price and considering how long buildings last, they'd pay for themselves many times over in the course of their lifetime.
Absolutely! That solar hasn't been mandatory on all new builds in recent years is such a missed opportunity
100%. The government has missed a trick by not making this compulsory on new build and replacements.
@Scratchy Ballzack That can be a way for supporting green transition from the government. They should pay the price difference between regular tiles and solar tiles as subsidy when you are installing new roof or renovating old one.
@Scratchy Ballzack We need a decent government!
@Scratchy Ballzack a fair point, I can't speak to American prices but in the UK all new build prices contain a very decent margin for the builder. Housing is ridiculously overpriced here too, my argument is that the free market has had plenty of time to do the right thing though.
As a hang glider pilot, I often find myself looking down on acres of roof space and wondered why new builds couldn't be legislated to have some kind of solar. I know it's not as straight forward as that but these panels seem like a great idea and get my vote.
they can, if we would tax hang gliding to pay for it....
@@nc3826 just as long as I can keep the duty free.
@Just think I did say it wasnt straight forward.
@Bagheera I see where you're coming from.
LIKE if you'd like these solar tiles on your house & SHARE if you think all buildings should generate their own power! Full description below...
Yes, it's a roof, but it's no ordinary roof. This roof that Robert has come to see is made up from 900 solar tiles! These tiles deliver all the benefits of solar, but without the aesthetic compromise of huge panels added onto your roof that require systems and structures to manage the weight and connections. Surely all buildings should have solar?

How well does it resist to hail the size of an orange?
Regarding Tesla solar roof, nothing done in Europe can't be solved by their engineers I would say.
Some cases may be specific but you can have a non solar tile where you need to cut them. That's just something to plan when doing the quote.
@@JeremyHamaoui I've seen better solar tiles than both invisible solar and Tesla. Solecco (Si, recycled plastic, tempered polycarbonate), so super lightweight no need for Aluminium, concrete or glass. Much lower carbon footprint. Hailproof too.

In the 70’s they had solar or just ambient light powered calculators. I’m wondering when solar power will be incorporated into clothing because they already have battery powered clothes
That's great! The other thing I'd like to see is solar power installations on parking lots. They could shade the cars, generate power, and divert rain water before it washes through all the grease and oil left behind by vehicles. In the States we have car parks that seem to go on past the horizon, all completely exposed to the Sun. Might as well get something out of it!
Why not charge up large batteries and sell to the ev s parked there.
Sure absolutely - put EV charging options on the support legs for the solar panels.
You don't get oil and grease in EV's, just sayin'......
@@mraidymaddful crazy how that works, isn't it? ;)
This has been done in a few places. The problem is it's virtue signalling & like all such things really, there are easier ways. The supports get driven into and damaged, maintenance is a pain, panels can be accessed/damaged/stolen. Far easier/cheaper to just put the solar in secure compound in some waste ground.
Well I have issues with my roof tiles as I type this and I do want to go solar, I might give these guys a call and see what is what. Nice.
Just remember hot tieles
Produce less
That's why solar is liftet off the roof
To cool the PV ..
This is a bad idea .. hot pv won't produce
@@kennethschultz6465 currently our in-roof (Exasun) PV is producing 1.65 kW as we speak on a cloudy day. Already seen 2.5 kW and waiting for a good day to see it finally reach it's peak output of 3 kW (it's on for two weeks now). So they can produce power! Probably a bit less, but it looks a lot better so there's that.
@@kennethschultz6465 my panels output about 30% more power when I give them a spray with the hose pipe but they still work.
Let me understand the proposition here. You are going to let these guys take a solid concrete tile and put a sizable hole in the middle of it and seal it with some glue and attach a plastic panel to it to sit out in the sun for decades? The panel has 1/3 the longevity of a solid tile (not sure the longevity of as tile with a hole in it). When the panel fails, you check all your panels and connections. You finally find the one that failed and you want to replace it... Just think it through. Maybe having panels attached on the outside is not that ugly after all?
At £30 per tile no thanks
Nice to see a UK product/company doing this!
Whether this system, Tesla solar roof or something else ought to be made more of a standard. I did back of the envelope calculation which says about 52m² on every household would give enough power for the whole country. And I am talking giving power to factories and such. The 52m² would cover more than the energy needs of the household itself. Households only consume about 30% of the power in a western country.
Obviously there are complicating factors here in that the power will not be delivered exactly when you need it. But it does give a sense of just how much potential there is in covering every roof. And 52m² is a pretty modest area. I would think a normal house roof is at least 80-100m².
But imagine having a house with 100m² solar panels. It will produce 75.00 kWh on average per day. That can charge up a typical Tesla car battery. However your average western household only needs about 10 kWh per day. So you actually got lots of power you can sell to the grid and make money. With the big Tesla car battery you can store this power and just sell it when there is demand to make a pretty penny.
And the neat thing about solar is that you can in principle expand as you got money. You don't need to build 100m², you could build smaller. Then make money off that for some years and later expand.
With the Tesla million miles battery and bidirectional charging we are going to see some crazy no opportunities for people to have energy independence and actually make money from their home house selling power.
In hot climate double roof is actually a benefit - it helps cool your house.
it also will prevent the roof from drying out properly. look underneath most roof systems that have had solar on them for a long time (aside from tile) and they are normally worn down prematurely. the sun is both the enemy & the friend of most roofs
@@BEATmyguest31 This is why a double-layer roof is actually a good thing.
You have the lower portion of the roof fully sealed, insulated and drained.
Between the two layers is a drainage plain and keeps the top deck cooler, extending the life of the roof itself.
Fantastic Robert! It’s Chris’s slate I’ve been looking at for our North Devon project I mentioned in our discussion earlier in the week about wind turbines and tidal. It’s a shame he didn’t have the slate to show off too but they are lighter and do exactly the same job. This is exactly what the government should be supporting. Soooo much potential out there. Great to see them going on a roof, thank you! 👍👍👍👍
Mark Jarvis I’ll drop off a sample of the slate version on a Tuesday

What's the point of using these with slate? You're only going to be covering them anyway aren't you?
@@MrGonzonator If you have a listed building with a slate roof or live in certain areas where slate roofs are mandated so they match other properties in the area then you don't get a choice.
@@DEADB33F wow, thats a truly absurd rule. If you have solar panels covering your roof, why should anyone care what's underneath them?
@@MrGonzonator In these cases as James referred too, over-roof solar panels would not be permitted either. At least not on a roof that can be seen by anyone or from anywhere.
I stumbled across your channel a few months ago, and it was bothering me wher I'd seen your face, then it came to me. Scrapheap Challenge.. CH4.. Great programme. Now here's the sinic in me, the big Big house builders should be made to do this, by law. Make every single new home self sufficient, not just power/heating, everything. Water, sewage everything. We have a farm, and spent £80,000 on solar set up, And not jut solar, wind power too. And on top of that We collect all the rain water, filter it, clean it, etc etc,, we have a bacteria septic waste system, never needs emptying, looks after its self. Yes, it costs money, but in the 5 years we've had it up+running it has now paid fit it's self.. We are almost now completely self sufficient. Even food now we grown ourselves, This is the future.
in austria you get incentives when building a new house and meeting some certain standards/requirements. eletric solar on the roof should be part of these requirements.
The UK could easily add such requirements to schemes such as Starter Home scheme. But it won't.
@ Stefan: You have elected already a Green Party President, perhaps try to do that for your government too the next time. ;)
@@TerraPosse the junior partner of the goverment is the green party
@@kona6812 I realised after I wrote that however the operative word here is 'junior'. Unless you can somehow spin green policies as also being anti-immigration you are not likely to get any traction with the OVP.
We have those incentives in America too. For anything solar, energy saving, tankless water heaters, whole home generators, impact windows & doors, smart home tech, etc.
I live in the U.S. and this is an AWESOME idea. This I would say is better than Tesla’s.
This won't work in the US on most existing residential buildings. Most existing US residential structures are engineered to support an asphalt shingle roof, which is much lighter per square-foot than these tiles which weight 10 pounds a piece. It would work on new construction where the building is designed to take the extra weight, but it would not be possible to retrofit these kinds of roof tiles to most existing US residential buildings.
It is easy to get excited by new technologies and applictions but I so think that this could be a real game changer on new builds or even with complete new roofs as it would attract far less negativity from planners, especially in more sensitive areas.
It's awesome seeing builders with clean energy generation in mind, along with storage as well ! So cool
I think new homes should be regulated to include renewable energy generation, water recovery (for gardens/toilets) and also higher construction standards to ensure that new homes are much more durable than the current batch of "disposable" homes that are currently thrown up.
Totally agree 👍🏼
What we currently see fires occuring in PV installions, built in roofs. The failures are generally caused by faulty connectors of the PV installation in combination with the built-in feature. When we look at this concept we see a lot of connections which can fail. The failure mode of the DC currents is that you get arcing and heating up of the connection, resulting in fires.
Solar is the most "no brainer" - clean power IMHO.
Properties of all kinds have lots of roof space + car parks (for e.g.) offer giant surface areas.
And as other people have commented, the right incentives and economies of scale will make it a ton cheaper in a short amount of time!
I love these solar tiles - let it be the first of many!
@barefoot arizona You've totally missed the point
This absolutely needed in my opinion as we redo or build new roofs, what a better way to reduce ones footprint, be part of the power generation, power our cars, reduce or eliminate fossil fuels, paired with batteries for storage , there many more option on house batteries today. Great content!
What a fantastic idea! All new houses houses should have these.
Absolutely, if I owned my roof it would have these invisible panels.
Read ages ago about a block of flats in Brooklyn that wired in their own, off grid solar roof, paid for by the community for the community. With the pandemic and all, with communities focussing on the benefits of Local, perhaps some funding from somewhere would be nice as an incentive. Great content, Fully Charged!
I like the idea of decentralising power generation
Given that most of the electrical power currently generated is lost during transmission, the closer we can generate the power to where it is consumed, the better.
What is the matter with governments, are they all asleep, they should be proactive with technology dragging everyone to have the latest, environment saving, money saving, devices. I am buying a new home in Monmouth, it is a tired 1966 bungalow with a south facing roof. The house is badly insulated & a new roof may be needed. We need to be encouraged to bring property up to date. We need a Green Government Guru to advise us, it would be so useful, instead we have to weed out what is best all by ourselves. I am older & just want to get on with it all without delay. These solar tiles look to be a very good idea, I must investigate. Fully Charged is one of my favourite sites, thanks so much for all your valuable advice Robert, you are such a special man, all best to you!
Loved it! It blows my mind that you’re doing solar roofs in the UK or Germany and yet those are rare as hell here in Spain 🇪🇸...
I believe it’s too hot in Spain. My mom lives there and that’s what she was told. 🤷🏼♂️
There are now tiles which have active cooling that have a heat pump, as part of the system, for heating some water
Scott Wills Nonsense. Here in Australia it is hotter than Spain and rooftop solar is massive here.
Spain has hot water solar tanks on the roofs, and it does have solar farms but wind turbines seem to be the majority of power by other means 21% of used electric in 2019.
@@scottwills4698 drivel
I'm very happy with my 20 Norwegian designed REC PV panels and ABB inverter.
They generate 8 .megawatts per annum . I have paid only $60 for electricity since this Solarhart system was installed 30 months ago. Payback on the system is 42 months. It was the best system for me. Tesla roofs are for people who dont have to care about money.
This is great!
Won't be competitive price-wise but great to see separate initiatives apart from tesla!
Yes! I've had this idea for over 25 years! and now it's reality...
This to me is like hybrid cars, retrofitting new tech on to old tech, what about the environmental cost of the concrete roof tiles? It would surely be better to stop using century old roofing systems and use modern light weight roofs that require less timber to support them. Also the added cost of this system is crazy!! I believe we need to design and build with solar in mind, large flat rectangular roofs made with metal insulated panels with solar on top. The air gap helps cool the panels and increases efficiency, holding on to tradition will only hold us back!
For me this system is for those with more money than sense, we need affordable and sustainable solutions so that everyone can benefit. Also what about the time to install those panels on the tiles and cutting the hole in them? how much does that cost?
Part of a roofs stability is it's mass, but agreed concrete isn't the most environmentally friendly material, I've often thought there must be a better way. Idk what recycled materials would be suitable though given it must be fireproof, insulating, UV stable etc. USA style shingles are garbage, flat roofs are worse, get back to mining slate in a more sustainable way?? Also, yes £30 a tile is a ripoff!
Killua Zoldyck Flat roofs are the worst for solar, they need to be angled towards the sun. Panels on a flat roof would need to be mounted on an angled frame, so you might as well just build the roof with the appropriate slope. Insurance companies hate flat roofs for a reason- they are notorious for leaks. I agree about concrete roof tiles- personally I think traditional slate is still a good choice- it's relatively low carbon, it lasts well over a century, and top quality slates can be reclaimed and reused. In fact, good reclaimed welsh slate tiles reclaimed from old buildings are more in demand and hence more expensive than brand new ones!
@DrgnFlys Concrete roof tiles with holes probably won't last 100 years. Solar panels certainly won't last 100 years. How do you replace these in 20 years when they start failing? Do you keep the concrete tile and just replace the PV module? In 20 years this company will be long gone and you are stuck with a roof full of holes and no power. Bad idea!
@@spencerwilton5831 I never said flat roofs, i have installed enough solar to know that LOL, I'm talking about insulated roof panels like we use on commercial buildings here, but they use on houses in other countries. Much lighter, less framing as they are themselves structural. Easy to install and easy to put solar panels on.

Great idea for a listed buildings where solar would otherwise not be possible.
Until the price comes down they're still going to be far too expensive for most though.
How are the solar cells glued to the tiles? and what's the long-term duration of that glue like?
If the glue fails you have tiles with holes in the middle all over your roof.
I think I'd at least like to have seen the holes at the back sealed around the edge with silicone sealant or something like that.
Cells are bonded with a modified structural polymer resin with a 30 year warranty
@@chrishall409 Thanks Chris. I take it more glue is applied than can be seen on the cell used as an example at 2:00? (as that doesn't seem to be particularly good coverage)
Would have been nice if Robert had covered some of this in the video as it seems most of the questions here are asking about stuff like this. Great to see you're clearing things up though.
Unfortunately in the "Comparision with Solar Panels" two, imho, major disadvantages were left untouched:
1) no cooling for the panels, actually they are heated up by the tiles - which means a great loss in efficency and also in longevity
2) in electrical installations the connectors are usualy (in long term) the most probable point of failure - and here we have a lot of them. And we are talking of a lifespan for a roof of more then 20-25 years...
It's for sure better then no solar at all - but for the sake of transparency this should be also pointed out
Great comment
Also, no way to "aim" the panels for the best view of the sun
Yes I thought of that also.
There are plenty of in roof PV systems available
50 % of that 30 pounds per solar tile is just in the connector
Finally! Great to see companies running with the aesthetic considerations and making it work.
I've been saying for the last 10 yrs all new builds should have at least 1kw per bedroom at construction to create a solar network across the country, still not sure about the batteries yet so I think we should sell what's made in the day and buy what's needed at night across countries. Overall there is still a cost but it should be about the same as what we have now, the win is a more stable grid energy and saving the planet.
Yes.
Not suitable if shaded though. For example a bungalow surrounded by trees.
What do you do during the winter when there isn't as much sun as in summer? You would have about 6 months of black out. You would still need nuclear, coal and gas powered stations.
YES, absolutely yes !
And not only solar panels on the roof but power wall battery is mandatory !
@pete smyth :)
I'd be interested to see the actual price difference for the whole system vs a traditional roof with a traditional solar panel on it.
If you never knew, to give some context, the top of the range system from tesla (2022 solar roof tiles) are on avg 19% efficient, which is not anywere near the 23.8% some top-end panels produce, so realistic you only buy this solar tiles if you want a roof that looks alittle different but doesnt have big panels on it :)
I had this very idea 26 years ago while working on a roof putting anti vandal tiles on.....great idea and about time it became a standard on all new houses
£30 per tile seems steep to me but it's early days yet and I'm sure it will reduce. Looks the business though good on them.
Not every tile is solar so it's not like the whole roof will be 30 pounds per tile
@@darrenit7498 From my calculation a 3.6 kW system would need 240 tiles which is £7400, that's more than you would pay for conventional but the result neater and depending on your POV better.
Because it is MADE IN ENGLAND.
@@DogsBAwesome That's £7400 for the solar panels AND the roof tiles, the price for a conventional setup doesn't include the cost of the tiles which would be extra on a new-build or re-roof.
@@rogerbarton497 If you are having your roof re-tiled or it's a new build and you can afford it sure go for it.
I have flat roofs, so this doesnt apply, but what a great product this is. No brainer that any new house should have solar from the start
An encouraging technology now in the UK. But it’s success will come down to large scale production dropping price significantly for mass adoption.
Good luck to them 👍
I have a 17kw solar roof system with 2 Tesla powerall2 batteries. I run my house, and my shop on solar. My average electric bill (after solar credits) is -$410 per month (yes, that is a minus). Haven't paid an electric bill in over 2 years. It's wonderful.
where are you located and what was the installed price if I may ask?
Where I live there are roughly 165,000 homes, it would be amazing if they all had solar rooftops.
@Just think just stop
I worked for Mitsubishi in Cirencester, we have 150 solar panels on warehouse roof, was done because we sold PHEV cars, the idea was we were charging cars with self generated electric power, we were ahead of the game
These look really nice, though it sounds like they’re using a single inverter per elevation which I think would suffer under patchy cloud cover vs a panelized system with an inverter for each panel.
It really is infuriating isn’t it when you see a field full of solar panels and a bunch of warehouses next door with none. Or if there’s a huge parking lot the same size right next to it. Or a giant housing development with no panels installed! It really is shameful I think to not fit panels to the many convenient spaces left in our built world and steal nature instead.
This is what is normal in South Australia. Only problem is those that don’t have Solar panels get bill shock during summer
Abram McCalment we are actually installing a single inverter for the entire project, with separate mppt trackers for each elevation.
Each tile has a bypass diode to optimise output individually removing the issue caused by partial shading.
I have Tesla roof tiles on my roof my system is 14.97kwh and it makes 50 to 70 kwh per day even on cloudy days.
with 2 inverters.
@@Slebonson The problem with Tesla tiles, as Chris explained very well, is that if you have a US style roof with gable ends you are OK, but only if the roof is a whole multiple of tiles long and wide. These solar tiles are identical in appearance to the non-solar, which can be cut to fit. Could you do that 4 aspect roof with Tesla? No.
In 2008 I project managed a new housing estate in Lytham St Anne's, building 111 social housing homes for rent. The scheme included two large blocks of 85 flats in total. All were built to Code for Sustainable Homes Level 4. The apartment blocks had solar interlocking roof tiles, provided by a UK company called Solar Century. The solar tiles were called C21E. Each solar tile was the length of three concrete tiles and interlocked with the concrete tiles and were wired in series. Like Tesla, this video gives the gives impression this manufacturer invented the concept of solar tiling interlocking with traditional roof tiles in 2010. In reality, Solar Century were doing the same, albeit with triple length rather than individual tiles, years before. We used the solar power generated to subsidise the energy used in the communal areas, to reduce service charges for lighting and lifts. From the ground, the solar arrays were virtually invisible. The scheme was loved by the local town planners.
Thanks, I actually started with Edilians solarmax, the predecessor to c21e, and still install today, the tiles are the first actual tile size product, that is not covered with glass
Solar tiles are such a no-brainer. Great episode guys ☀️⚡☀️⚡
yes they should, they should be designed and built with efficiency in mind, and anything that does this whilst maintaining aesthetics is great.
Please do a video about Marley's solar tile, which is the same size of a solar panel but integrates into the roof like a Velux window would so you save on the cost of concrete tiles.
Eight years ago I just couldn't find a supplier for similar products, so I had the large bolt on framework installed. The roof was designed for the extra loadings. One advantage is that the air gap acts as a tropical roof on sunny days, keeping the underlying tiles cooler.
It should be illegal to build a none solar PV roof , preferably with a well designed battery system included.
@James Clifford I did actually try to get a price for solar tiles from Solar Century, The salesman couldn't be bothered to reply to my enquiry. He didn't want to bother with a self build customer. So of course I went elsewhere.
My house does have Solar PV, Solar Thermal for water and Underfloor heating as reqd. Ground pipe Air supply plus underfloor extract for air supply, (gives fresh air at 16deg in summer for cooling and in winter at 14deg even on the frostiest day. Heat recovery in the ventilation system. ASHPs to supply underfloor heating by freezing the used warm air being expelled .
The house has insulated underfloor , 200 mm wall insulation and a SIPS roof.
The garage/ hobby room is heated by ASHP,
During sunny days the car is solar charged.
Our Electricity bill for a 230 sq mtr house is less than for my mother in laws 50 sq mtr semi. even including 15000 miles for the car.
Careful design and good choice of materials are worthwhile.
@James Clifford Agreed, first we designed a Tea cosy, then decided how to fit it out!
@fullychargedshow The situation is worse than you think... A chap I met was buying a new build just west of Swindon, Not only wouldn't the builders offer ANY sort of PV as an option, the deeds on the house prevented him from installing them for three years.... I assume that if PV was installed the electric company would refuse to connect them to the grid ?
Solar PV should be mandatory !
I have 2 questions:
1 how susceptible to leakage are these tiles? From what I can see, these are glued onto the normal concrete tile? What if the glue bond fails? Surely then there’s a hole in the roof, letting in rain?!
2 it appears that these are wired in sequence? If one tiles electronics fail, does that then stop the entire row/roof from working? Or are there backups to ensure this doesn’t happen?
Hi! Sorry, I don't know anything about wiring solar panels, but I think I can answer your other question...
Any rain or snow that got under a tile would fall onto the flexible membrane beneath, and run down into the gutter. That's what happens on regular roofs now if gales blow water back up under the tiles.
The roof's hard concrete, ceramic, or slate outer covering is really only there to protect the waterproof membrane underneath from gales, storms, hail, ice, and UV damage. It's the soft membrane that makes a roof watertight, not the tiles. :-)
Elli P ahh ok I didn’t know that, thank you! Hopefully there are no holes for the cables to go through the membrane 😜
pete smyth oh well that’s confusing! I guess it all works together?
Haven’t watched the video but yes absolutely every house should have solar panels and battery storage
That would be awesome in Australia. Also preferred how they did the underlying roof stronger than the typical method used here and I'd demand they built my tile roof the same as the UK. To get 13+ kW as well on a house would be fantastic.
I would like to thank Mark & Julie from Batley, W. Yorks for the first order as a result of seeing the tiles on this episode.
We are to provide the full roof for their new build, which includes 6 kWp of solar tiles, 10 kWhours of battery storage, and all inverters etc for less than £22,000.
That actually doesn't sound too unrealistic. I'd like a link to the website too please.....
Great initiative .. will be a no brainer for future house builts!
Just the video I needed, really wanted a Tesla roof, but God knows when they will come to the UK. Might settle with a UK based company.
You can only hope they never do -;you'll spend the rest of your life paying back the loan .......!
Don't bother normal solar panels. You can almost buy 400w panels for 140 bucks. Whats the point 🤔
You're not settling. Support someone who has worked in the industry for decades and knows how to install roofs. Not some pipe dream company run by teenagers and fresh grads with little experience outside of poached talent.
Tesla tiles are shit, they're workers work in appalling conditions and they are over priced and set on fire. Why in the world do you want one. Daddy Elon isn't going to let you suck him off if you do.
Why would you even want to send your money to a non-UK company if you live in UK? Second, Tesla tiles would have to be shipped across half of the world in their full shape. Sure they are lighter, but still entire roof has to sail across the seas.
At last, this is my bag, as a architectural technologist for the last 30 years.. I think I will be specify these as an option on my new and existing structures I design.
Daniel Farrant look forward to helping you with the details of your future designs
£30 for a 15W panel? It's only a no brainer product when the price comes down to something more economically viable.
exactly it's very over priced currently!.
It may be overpriced for one household to have retrofitted. But a big saving when installed during construction- no labour costs for Installing solar panels and framework, no increased engineering costs related to making a roof strong enough to take the weight of panels. Thats a Winner for a construction firm.
looks like about a 7 year payback on simple terms
no worries, if this is indeed feasible, the chinese will make one for 5 pounds probably :)
But don’t forget, for your £30 you get a roof tile not just a 15 watt solar module.
As with all products, small batch hand made products are initially expensive, with volumes and related economies of scale, prices will continue to fall, in 2018 they were £34 each.
Hell yeah, expensive solar tiles that mostly don't even face the sun!
Why didn't we think of this earlier?
Installer: "Its about 30 pounds a tile"
Interviewer: "...oh . . .wow"
$27,000 just for the tiles on this roof. Not a hater at all - I hope we all have this one day on every roof but there is a reason why we dont at the moment.
That would be $34,500 dollars, not £27,000 pounds going to be a very long time before that becomes viable for your average housebuilder or even self builder
@Bagheera These tiles should weigh about the same as the normal concrete tiles. The hole drilled through the concrete tile should offset the weight of the photovoltaic panels and wiring. I do agree, however, that the price is a bit steep.
@@TheGuyThatEveryoneIgnores drilling holes in tiles... sounds like a leak waiting to happen, considering every tile has a hole in it!!
I love that there are alternative to placing solar on your roof. Solar tiles...! Wonderful :)
The process is still wrong.
You don’t NEED a cement tile backing the solar panel.
The purpose of the cement tile is to protect the waterproof sheet.
If the solar panel can do that alone, you don’t need a heavy, expensive, cement tile.
Just make the solar panels a little more robust to protect the waterproof underlayment fabric!
Not only that, the cement tiles hold heat!
Without them, the solar panels would stay cooler.
The cement tiles are dead cheap and ubiquitous. Making the solar tile do it all is much more expensive- like the Tesla tiles.
Cement is really bad for the environment due to the enormous co2 output of production. So do away with cement.
Correct - its pointless. Same thing as normal tiled roof and solar panels, except much more expensive and difficult to install. Better concept would be to eliminate the tiles all together and design the roof to integrate purpose designed larger panels..
Mr. Quindazzi, cement tiles are not cheap. Plus they are a unnecessary heat sink. Keeping temperatures Higher, for quicker degradation of solar panels. And less effective electric production.
Mr. Quindazzi. A simple rigid edge of plastic is all you need. It wouldn’t cost more than a few more pennies per panel.
Tesla solar roof tiles don't go all the way to the edge. If you look carefully at their literature, you'll see standard matching tiles to cover edges, awkward bits & areas where solar doesn't make sense. As far as I'm aware, those tiles are cut to size on-site where necessary.
My one query about the fabulous solar tiles featured in today's video is how is the concrete made? Concrete manufacturing being very polluting CO2 wise. What mitigation measures are being used by the tile manufacturers to counter excess emissions? Perhaps advances in concrete manufacturing could be a topic for a future video.
when this is cheaper than normal solar it will be big but until that point I can't see this becoming mass market.
well it's never going to be cheaper than "normal" solar as these tiles have to do more than one thing.
900 solar tiles on this building at an extra 29 pound per tile - 26,100 extra. Seems alot.
Right. solar tiles have been around a long time (12 years?), but always significantly more expensive. Unless planners mandate them or you _really_ don't want the standard large panels they aren't very interesting and almost everyone picks the standard scheme. You can also get built-in standard panels and gasketed panels where the panels are the roof. France mandates BIPV (or did) so it's a lot more popular there.
Do hope they are fitted with an air gap as black glass gets extremely hot! During hot very sunny days can see that getting into the home even with best insulation.
@@GlenisRetiredNZ At 15W per panel it is a 13.5kW system, which can cost as much when done with panels. In theory the solar roof goes on as one build and would be cheaper than building a roof and then hiring a separate crew to install solar panels. Also, that is a tile roof and while you can put panels on one I have heard that the frames they need to use for it are fugly. Plus, why would you get a tile roof in the first place and then cover it up even if you don't think panels look bad?
I don't think installers are incompetent enough to cause leaks these days, but putting the panels on frames that allow wind under them for cooling also means a stiff wind risks pulling up the frame, at which point it might go flying away if it is not nailed to your roof and could rip off your roof if it is. Many installers actually seem to advertise how they set the panels flush with the roof to avoid making them stand out, so I don't know how valid the argument about panels getting better cooling because air gets below them is anyway.
TL;DR: It's never going to be cheaper than just solar panels, but if you are building a new roof you can get more solar power on it at same or cheaper price and make it look better than if you added panels.
They use PTFE solar modules, which are bit better version of flexible solar modules, which are actually the worst(average life -3 years). The PTFE solar modules have average life of 5-7 years, in this case , since they have mounted this within a solid roof, the average life can be as much as 10+ years. In comparison, Normal glass solar modules have 25-30 years of warranty. I try to dig information from the link provided and although the company provide 30 years warranty on the actual roof there was no mention of the solar module because they get it from another company called viridiansolar. I went into check their site, but didn't find any warranty information on their PTFE modules. so if it has only 10+ years of average lifetime that would be a significant waste of resource. Anybody please correct me if I am wrong or you find some more information on this.
What is with the heating up of the panels in direct sunlight? As I recall solar panels loose efficiency when their temperature rises and the traditional way of building a solar roof enables the panels to have cooling by fresh air being able to circulate underneath the panels, isn't it? So these roof tiles would have a worse efficiency?
Good question. Anyone know?
As a guess I'd day having them on a cement tile would help dissipate the gest into the tile somewhat. But that's just a guess. The roof is still black after all and cement can hold heat for a while so not really sure still. Good point though.
I don’t suspect peak temperatures are much higher, largely since I also suspect air cooling benefit under a normal panel is negligible. Now. . . add water cooling and harvest the waste heat to pre-heat hot water and reduce heating load in the winter and you’ll have an extra high performance roof!
I was thinking the same thing, maybe only good for cooler climates
It is part of the reason why I am skeptic of this. The other is that it is likely much more serial panels connected in each array which can cause problems for the charge controller. Most likely you will end up with a more expensive multiple charge controller solution if you go with this system than just adding larger panels.
Cracking vid. We said why didn’t everyone have these on newbuilds years ago. Cheers R👍
BEST IDEA EVER IMO!! well done
I live in Scotland, hipped roofs can get in the bin. Gables all the waaaaay. A very valid point about that issue that will definitely be faced installing those Tesla tiles around openings/dormers etc.
My only concern with these is that each tile is individually glued on. How will these adhesives cope with 25 years worth of winters with frost creeping in between the layers? If even one is sub-par you have a hole into your roof and your electrical systems, and then you have to rip the whole lot off.
At least with the standalone systems the fixings are under the tiles and do not compromise the integrity of the roof itself. Alternatively with the Tesla offering, the tile and panel are one and the same.
Freeze at 1:46 to see what I mean.
This would be my main concern.
If you look at 2:13 there isn't even any sealant around the hole at the back. I would at least have liked to see that gap around the junction box potted with epoxy or silicone.
@@DEADB33F exactly my concern. Once you get a roof leak you are going to need to test integrity of a large number of tiles to find the faulty tile.
Also flat concrete tiles are fairly rare where I live. How flexible are planners going to be if I change my roman tiles to flat?
@@DEADB33F perhaps the adhesive that fixes the panel to the tile seals round the hole
It's perfectly easy just to replace one tile without removing the whole roof, probably easier and cheaper than replacing a conventional panel if part of that fails.
Hi Robert, thanks for the Audi story (rant) the other day, I shared the German article with all my car friends.
Interesting with the tiles also! It is truly the next generation, instead of bolting strange blue and aluminium things to your house.
Ok, when it comes to costs, and please feel free to correct me on this: from the video, a traditional concrete tile is £1 (making it £10 per square meter). A solar tile is £30 (making it £300 per square meter). Essentially this roof is 30 times more expensive than a traditional roof. The economics work a little bit better if you compare a roof tiled with solar tiles to a normal roof plus panels BUT not by much.
I am all in on solar (have panels on my roof) but I’m not sure the economics of these type of solar tiles makes enough sense. Also, version 3 of the Tesla solar tiles just got cheaper. I cannot remember the exact figures right now but I remember them being far more competitively priced compared to traditional roofs.
Again, I reserve the right to be completely wrong here and I stand to be corrected.
I think he said it works out 50% more than roof + conventional panels. Its an aesthetic choice at present, rather than an economic one.
It would be cheaper and better to get a standing seam metal roof and regular solar panels. You dont screw through the roof to attach the panels as they clamp onto the metal seam. These solar tiles are retarded and driven by rich, vain people who dont want their house to look funny.
Material costs, yes. But once you add in labour, scaffold etc. it works out at 50% more.
The reason you can have a tile that is 30X more expensive but only add 50 percent to the overall cost is that the labour cost makes up such a big part of the cost of any installation.
@@instanoodlesNot just rich vain people but it likely also going to be drive by people who live in conservation areas who aren't allow traditional solar roofs.
Another excellent video Robert - thank you!
The only thing I found a bit odd was that the roofing contractor was having to cut a hole in the plain concrete tile to facilitate installation of the electrical component. This adds time, creates waste which adds cost so I wonder why they can't have the tiles made with the hole already formed as part of the casting process?
I'm sure that tile manufacturers aren't doing this now because there isn't a big enough demand for them but hopefully this will change. When it does, the cost of having a "solarised" roof will reduce and so become even more of a no-brainer!😁
think the solar tile is assembled in the country but it shipped as the base component to save weight. my main concern is adding multiple new holes to the roof which aren't covered by the title above
Question - if the rows are done in series, what happens when a panel fails and causes the entire set of panels to fail. How hard is it to find the faulty panel and fix it?
I suspect you get the same problem with conventional panels. If it fails open circuit you lose the row, if it fails short circuit you get lower output. i suppose to find the fault you get up there with a voltmeter!
@@rogerbarton497 Good luck with that. The only way to access the wires is by removing panels. Basically you'd end up removing a big chunk of the roof to find a fault.
I was wondering this as well. I wonder if you could access the cabling from behind. I also wondered if these are interchangeable with normal roofing tiles in the event a panel failed (in a way it was letting water in) and the company was no longer around.
@@rogerbarton497 Many panels come with micro inverters now a days. These will often be able to detect if a panel is producing output, and if not, disconnect the panel from the series. This way you never lose a full series of panels.
Brian Jensen exactly how SolarEdge works and it also tells you which panel is at fault so less need to guess
If government mandated that a minimum of 80% of a roof area of a new build must be consist of solar panels then prices would fall as manufacturers would scale up operations to meet the opportunity. Falling prices would encourage people who live in older properties to use solar tiles when they come to reroof their homes.
Good to see, 50% premium for a pretty roof, roof tax, Tesla do have tiles that are non solar for edges and hips.... hhhmmm

I do believe that governments around the world need to mandate that all new roofs must have solar of some kind
imagine those tiles under 3 feet of snow, just when you need the most energy being produced? also, the cost is 3 to 4 times the cost of any roof in North America and those tiles are not available anywhere other than EU, so no availability of materials, no return on a cost that is 3 to 4 times more than regular and no electricity production during at least 5 months out of the year also the electricity rate in North America is so low that it would take 100 years to just pay for the tiles and no electricity so you still have to pay for it, where is the value?\Why would anyone install a solar roof if they are not living in a very hot country where it is efficient at least most of the time?
I have an electric car because I do not drive a lot and electricity is extremely cheap here, I spend 1 pound per charge or 1 pound per week on charging my car for 165km range. 1 pound for a 40 kilowatt of charge per week. why would I pay 30 pounds per tile to produce electricity that cost less than 10 cents per kilowatt?
Apparently Tesla are now working with third party installers in US, and I came across a piece from the head of (I think) Good Faith energy with a picture of his Tesla-cvered roof, and it it has hips, gables the works. So it looks as if they have progressed from simple rectangular sloped roofs

@Buster Jangle lmao - that makes jeremy corbyn a closet tory....
@Buster Jangle You craaaazy bro! :D
This is one of those "now why hasn't anyone thought of that before" moments. Rather clever. Obviously, more care is needed during installation to avoid damage to the cells, but there's no doubt this is a step forward. It will meet with the approval of many planners too..... The only reservation I'd have would perhaps be the later possibility of damage caused by anyone installing or repairing a TV aerial or Sky dish etc.......
concrete tile not very environmental
what's the offset?
given that the foor will have the concrete tiles anyway , there is not much difference.
It's not so bad when you consider that a well laid roof can last for 100+ years.
meanwhile... roadways are laughing at the tiny amount of concrete going onto your roof.
Every house should have this. I have just bought a brand new house and the builders would not offer us solar panels of any description, I was appalled. If I want solar panels I have to have someone come in after we move in and retrofit.
Cost me £500 just for scaffolding, 3 stories high.
It just makes sense when you can recess panels and save the cost and weight of some roofing tiles.
No question about durability? How well do these handle hail when there's no thick protective glass?
Im pretty sure they tested it
that was a missing question.... i would have thought it would have been one of the first.
Yes they should especially those big boxes of buildings should have solar and if room windmills it may not totally provide all the of their power needs but every bit they make for their own use is less taken from the grid.
There are lots of those big box warehouse going up where I live now and I don't think Solar is part of the planning.
California needs to this.
Invisible Solar.. Love the ring of that..
Though, I also like the look of "traditional" solar panels
Only there not invisible... you can clearly see which tiles have panels on and which don't, better to stick to traditional panels!!
@@killuazoldyck1352 why is it better? Why would adding dynamic stress to the roof be better? Putting "types of stress" on the roof that the roof was never designed for is better? Please give your reasoning?
@@ColinRichardson roofs are designed to handle dynamic stress, a roof acts like a large aerofoil, it is subject to high pressure wind loads and low pressure wind loads depending on the direction of the wind. That guy was clearly selling his product and trying to justify the huge extra cost. How many roofs with traditional solar panels have failed because of dynamic stress? Also the extra materials concerns me, 2 MC4 connectors per 15w instead of 2 MC4 connectors per 250w, plus the little junction boxes. to me that is wasteful, larger panels are far more environmentally friendly and efficient. Fault finding would be a nightmare to, that many panels in series would make it hard to find a fault. To me this product is badly floored, it has been around for a long time and barely anyone has used it because from an engineering point of view it makes no sense, nothing more than a gimmick like hybrid cars.
@@killuazoldyck1352 Sorry, I got 6 words in and already stopped reading, since you obviously read my comment but didn't comprehend it.. Try again.. If you comprehend it the second time around and you comment I'll possibly read it more fully.
The guy that installed my system recently was installing JA 320w solar panels that now cost £100 each. ie. 3w per £1. Or £1.20 including racking. So these are £30 for 30w. That's nearly 3x the price. You also have a lot of cabling. Like Tesla it might be more efficient to have 3 panels in a row for 90w, then you don't need so many connectors. If you get one poorly fitted connector then you lose the lot and it's harder to diagnose. I imagine as there's nothing behind there there should be no fault. But one bite from a squirrel and the lot might go down! At least with solar panels a fault could be diagnosed to the panel and that replaced without undermining the water protection of the roof.
Was so excited then you lost me when the price was discussed.
I know right!
It does seem a lot, but to make a fair comparison you'd need the price of a non-solar tile roof + the price of an installed solar system on top of it. Remember, this isn't just your solar system, it's your entire roof. Still sounds very expensive though....
The cost is approx 50% dearer than an ugly bolt on solar system, but fir that increased cost you get a roof as well as the solar

What you say is true, but on a new build what’s an extra 5-7 grand over a normal solar setup. It won’t add that much to the mortgage repayment.
The Tesla sole roof tiles, are cheaper than a new roof and solar!
Solar tiles and slates have been around in the UK at least since 2010. They just never took off because it was way more expensive per W than over-roof solar panels that were made in the millions. It sure looks better but most people are not too bothered with the look of their roofs once it means spending £ '000's more.
There are also some real drawbacks. One is in the case of a module / cell failure it will be problematic to locate the tile that failed (unless they use micro inverters I suppose), replace the faulty module / tile and pray that the wiring is accessible and not buried in insulation. Secondly the air flow he mentioned under over-roof panels is actually a feature and not a bug (sure storms can cause panels to be lifted off but that's not something I have yet come across). The hotter the modules become the more resistance there is to current flow, reducing the efficiency of the modules on them sunny summer days. Over-roof panels have some airflow alleviating this issue to some degree. Solar tiles have no such airflow. They have some thermal mass in form of the concrete tile but whatever that heats up to in the summer is what the solar modules will have to work at.
Not trying to be party pooper, it is a good idea / product for the right application. It's not the best thing since the invention of sliced bread though. Peace out. ;-)
He didn’t really understand how Tesla’s tiles work. They have tiles without solar in them that can be cut to match the shape of the roof. I’d be more interested to hear how these compare in terms of cell efficiency, relative cost, and assembly time. I’m also surprised Tesla didn’t have a patent on the solar tile idea.
The idea of bonding solar panels to roof tiles has been around for decades. It was just the cost of the panels holding things back.
....Even if it was previously patented that patent would have run out long ago.
James Bradwell Tesla’s thing was covering the solar cells so they can’t be seen from the ground. Do these not do that?
@@keco185 You only have to watch the video to realize the solar tile sits on top of the concrete tile and is visible.
Jean-Pierre White I watched the video. I thought they were only visible because we were looking dead-on at them. I was still thinking there was a film on top that hid them from the ground
Some tesla roof tiles doesnt have solar panels and those are used for contours or places where a square shape cannot fit
In North America most houses use asphalt shingles that need to be replaced every 10 to 15 years, the concrete roofing tiles would be great here except theses a whole industry based on making, repairing and replacing asphalt shingles. Glad when I built my house I put on a steal roof, that now has solar panels on it.
These solar tiles would be great here.
How durable are they, I noticed the installer standing on them
that is a good question as well. those thin solar panels usually have a very short lifespan. also they did not talk about for how long the warranty is.
@@ursodermatt8809 Personal side question, you seem to be from Switzerland ...... are you in the solar business? Looking around for products and services in Switzerland ....
@@Hippabellita1
i have a swiss name live in australia though. please use google to look for your services.
@@ursodermatt8809 thanks for answering and have a great weekend!
Standing on solar panels, or these tiles, introduces cracks in the cells, that reduces the output power of that cell
A lot of companies don't have solar panels on their roof because even if their were willing to do it their roof is simply nto designed to support the weight of the installation. This is pretty much what happened where i work, the cost of work to make it possible is so high that it stop being efficient in any way.
Wow , 10 lbs each tile is heavy !
Otherwise they will fly away😆
Sripal Devadoss , not too close to the sun I hope.
Yeah concrete tile roofs are scary heavy, I worked on a building site where the design of the roof trusses was wrong, they had a half truss butting up to a full truss at 90 degs, with basically just nails attaching it, when the roofer put the tiles on, the half truss started to slid downwards bending the nails with the weight, we had to jack it up and wedge a half dozen 4x2 under it and ramset them to middle of the lounge floor to stop it collapsing. They had to make this U shaped saddle assemble that hung over the full truss to the supported the half truss, It was a total pain to install and we total screwed up the roof doing it, the roofer was up there for days fixing the mess we made, swearing and tossing broken tiles off the roof.
taznz1 the stuff of nightmares ; I can imagine what that situation was like with tea breaks even having to be postponed . I would never have guessed those tiles weighed over ten pounds from the way they were lobbing them up and handling them though.
Richard Ward-Jackson My aunt lives in a 400 plus year old Cotswold stone house roofed entirely in stone. Some of them are two or more inches thick- the whole roof must weigh a couple of hundred tons- quite scary when your living underneath! Still, it's held up by a forest worth of huge oak beams and has been there for centuries, so I guess it's OK..
It's a great concept, not sure if the developers would swing for it, but if affordable housing could have them, that would be a start. Of course the buck stops with someone, I wonder who that'll be.
Solar Freakin' Rooftiles!
🤣
As smart as Solar Roads
Kenneth Schultz we need solar hats then we can charge Our phones while outside enjoying nature.
@@ZzHasbrozZ there's lots of companies that make solar phone chargers already. They've been around for several years.
Carie Saad I don’t remember why I commented on his comment to begin with. Maybe he edited the comment. I was probably trying to make a joke.
Shipping just the solar plate makes sense, but cutting holes in concrete tiles, then forming an intricate loom of wiring seems very tedious & labour/time intensive.
As a suggestion, maybe manageably-sized semi-rigid foam sections, which have pre-installed bus-bars embedded, along with waterproof click together electrical connectors.
Foam being light & having insulative properties could make the complete install process very efficient & cost-effective.
The question I have about all of these PV systems, and their attached technology like vehicle to home power, is what happens if their is a massive solar flare ? Are these systems protected from EMP events or will you lose your home and auto all at once and be left up the proverbial creek ?
Where on earth did you hear that from? Absolutely nothing will happen. We are protected by the atmosphere from the UV and the bulk of the radiation. The EMP (Geomagnetically induced current) (GIC) even in a major event will only be important for very long conductors, not like those you get in a roof. You won't see large pulses on the domestic mains supply either. This is a distribution problem. OK - so if you have one of the new power walls your lights might still be on afterwards if there is a power cut.
@@mikewillis1592 Absolutely nothing ? That's certainly not the position of industry experts. It's well known there have been massive power outages due to CME as well as the fact that EMP weapons are a real threat to modern society. It's a given solar power inverters will be burned out, lose their fusing, and require repair from a significant CME let alone human use of EMP weapons. Given these facts are not in dispute by anyone in the power industry it's a completely valid question...what happens if your EV is plugged into your home during a significant CME or if some nut uses an EMP.
How long do the panels last (or are expected to last)? Is there a maintenance interval? Scaffolding needed for maintenance (cost etc). A roof covering has anything from a 40 to 100 year life depending on location and material used. Unrelated points - on a wind turbine could the structure and turbine blades be covered in solar materials to further increase efficiency (flexible solar panels on a roll is on the Horizon)? For many years we have heard about energy generated from pressure plates installed in the floor/paving in busy locations (rail stations, shopping centres & busy urban streets)? Does not appear to be a high uptake on this - an update on the latest innovations would be good to see. Keep the content coming. Thanks.
