@@GustavSvard the solarmass solar panel element (you see the brand @1:14) which they have on the slate, its company is now longer about, their last twitter post was 2016. but alll they were doing is drilling massive holes into every slate lol sure a better way than that. sure I guess that's why its not around anymore
This is the way to build a solar roof. Not as an after thought but built in right from the start. Love it and wish the company every success. Thanks for sharing.
solar is awful in the UK the winter when you need the energy there is only about 7 hours of poor quality light and in the summer you make most of your energy that you don't need or use and then you sell it to the grid at about 20% the price you get charged for the electric so you basically install solar and you sell a KWh for 6-7p to the grid that then sells that KWh to your neighbours for 5 times that price so your really just making the energy companies money from your roof and your investment pointless
Conversly you could install slaor panel trays this saves the cost of the roof tiles over the tray area,reduces the roofing dead laod, gives a more flush roof appearance and avoids much of the wing problems with solar arrays fixed to the roof surface..
In the southern US, solar on the south facing roofs on houses can supply all the electricity needed for that house. Of course it would help to orient all house roofs north to south and move all vent pipes on the north side of the roof. Also making the southern side of the roof a consistent surface with no widows peaks or such architecture garbage.
This is brilliant! It is obvious this will soon be the norm in the building industry everywhere, it is so simply and elegantly the right thing to do. This feels just like seeing the beginnings of the phone tech industry in the early 2000 and already seeing where it is going to lead. The future looks so fascinating and I cannot wait to see where these innovations are leading us.
its 30-300x the cost of a non solar roof and 2x the cost of a regular solar installation based on what this guy said. i highly doubt it will ever be the norm, but it will become more common. remember, tesla tried doing this and have failed so far, likely because they underestimated cost and difficulty. youre bound to see much more regular roofs with solar on top for now, even new developments.
@@jonathanodude6660 Costs are going down at record speeds, and the trend accelerates even further as time goes by. I would agree, that there will likely be need for solar on top of regular roofs as well. The future looks very interesting nonetheless!
@@blackcoffeeandbooks8884 I think that once the price is measured in %s rather than multiples, you’d see a mass movement towards these types of roofs in all new builds, but until then, it’ll be a niche market for those rich enough to care about aesthetics over practicality.
Solar tiles are a great idea but £30 a tile is a very tough pill to swallow, especially as the panel is less efficient and will be at point of replacement around 20 years before the tile itself, I am glad to see people buying it to further fund the R&D but this is not for us mere mortals just yet, Keep the development going and the prices dropping and one day
Would it be a good idea to change the planning laws so that all new roofs would be lean-to type with South facing orientation? This would mean that close to 100% of every roof would be South facing
Did he say £30 and 900 tiles £27000 seems pretty high for a system that is reliant on silicon to make it watertight and adhere the panels to the tiles in extreme cold and heat. Biggest thing that I have with these is, it’s a lot of tiles to have in series so if you have one tile go down then that knocks out the other 44tiles 😮 think they should have some sort of optimisers. On a side note I wonder how efficient those panels are as it’s not just about having solar it is the make up of the cells and also the degradation of the cells over the life of the product.
While I like the idea in principle, and it looks much better I do have a couple of issues. 1. (As mentioned by others) the hole in every tile and a small bead of adhesive to bond the cell to the tile is not going to last long or be 100% perfect for every tile. This means leaks. 2. Roof tiles life probably exceeds 50-60 years, solar panels probably 20 years or so before losing efficiency. And with this it's a new roof when the solar panels need replacing.
Great idea, however hasn’t the hole and sealant just put a potential leak path in to every roof tile? It’s just a case of when the sealant will give up and leak then you may have many many leaks! As an engineer that seems a fatal flaw in the system. Solve that and your on to a winner.
Leaks and dribbles aren't a problem. 🙂 Every roof in soggy, stormy Britain (your location may vary🌞!) has 'underfelt' - a tough, flexible, continuous, waterproof membrane to stop any wind-driven rain and snow that blows back up under the slates and tiles from entering the roof space. Any water driven under the outer roof cladding then gathers on the waterproof membrane and runs down the roof UNDER the tiles, directly into the same gutter that collects the rain falling on the outside of the roof. Even if tiles are cracked, holed or missing completely, a felted roof is still waterproof. The hard outer shell (concrete, slate, terracotta or stone) is really only there to protect the waterproof membrane underneath from mechanical and environmental damage (UV light, hailstones, gales, snow, ice, birds, reindeer, etc). A modern thatched roof will also have the same type of waterproof membrane under the reeds.
@@EleanorPeterson Not strictly true, the felt (or these days breathable membrane) is only there to provide temporary weather resistance before the tiles are fitted, and after that the main function is to prevent wind uplift, and occasionally deal with fine wind driven snow. The tiles remain the sole waterproof covering, so any leakage is a serious problem if not dealt with immediately. It doesn't take long for felt underlay to degrade if a tile breaks or goes missing.
@@mikebarry229 That was my knowledge too, while the membrane will give some water resistance it’s not roofing felt anymore. I think it’s a simple fix, ensure the something covers the entire tile, actual PV would be daft given it get lapped, but surely some extra material extended to cover the tile, perhaps the electrical connections could go through the top then and avoid any hole drilling entirely on the tile?
They're no where near as efficient as panels at the moment though, I looked into these when I was looking at getting solar on my roof and standard panels were the better option. Might change in the future though
@@thomasfrederiksendk yes, agreed that would be a good application. I'm sure the efficiency will also improve over time, as there are a few areas on my roof that I'd like to cover with them when that happens
@@BSJWright I live in a low grade listed building, with restrictions on modifications to the outer shell only. Panels are a 100% no-go, but we might just get red ceramic tiles with solar built in approved if we ask nicely - and I’m hoping they’ll be much better when the roof is slated (pun intended) for replacement in 25 years.
@@thomasfrederiksendk That's true. But, the economic justification for installing the solar system in the first place weakens when the efficiency goes down. If you can't get enough power to recoup the installation cost through electricity savings within a reasonable time period, it's not worth it.
The answer for the dynamic loading caused by external solar panels is to modify the roof design to take that loading into account before building. My own roof , SIPS, came with 22 pages of calculations to show it was suitable for solar panels, solar thermal and keeping the rain out and the wind away.
The maths just doesn't add up... Each tile is 15w at a cost of £30 each. Average 400w panel is around £200 these days. 400/15 = 27 tiles (rounded up) to output a similar amount 27 x £30 = £810 for the same amount of output. Not to mention the surface area of 27 of these tiles would be far greater than a single panel. It would be far cheaper and much more efficient to get a standard roof and then add the panels on top.
imagine having a bad connection in one of them . maybe they do 1 run of the tiles and then some sort of monitoring module. i would hate to check 600 connections :-)
As a sparky, that was my thought as well! Too many joints for me , every connection is a point of failure. F or me , I'll stick to my panels. Gregg :-)
Marley did solar roof tiles at least 15 years ago if not before, they were installed on Southampton university and had a live web page to view the results in 2004. They stopped because of poor take up but now they are doing them again.
Different products, first was in in tile replacement glass module, their new solar tile is a standard module laid in the roof in place of tiles, it is not a solar tile in the way that these are
It's called recycling, take a video previously released years ago & re-release it via another channel. It magically appears in someone suggested TH-cam list as a new video. Double ad revenue for the same product. To be fair they do disclose this in a pinned comment as a "refreshed edit of a very popular release".
I've got roof integrated PV panels. They are ordinary PV panels with a special mounting adapter made by a company called GSE. It's smarter looking than an "on-roof" system, and it dramatically reduces static load on the roof. It's been in operation for 2 years and has withstood Storm Arwen, Malik and Corrie without damage, and it's shed some of the worst torrential summer downpours I've seen without leakage. This looks good, but the labour costs are much higher for installation and because of the number of individual elements and connections, the warranty callouts are likely to be higher than they would be for ordinary panels. There's also a complete lack of choice in this form factor, so warranty issues in the years to come are likely to be met with obsolescence issues, whereas standard sized panels will probably have plenty of replacement options to choose from. Since the pandemic, I've been tracking the PV/Concrete tile price ratio. Prepandemic, it was £10/sq metre for concrete tiles, vs £50/sq metre for solar PV. So price ratio was about 5. Now it's £20/sq metre for concrete tiles, but £100/sq metre for solar PV. Price ratio is the same. So personally, I think trending solar PV tech will focus on reducing rooftop costs. That means lighter rooftops which also benefit from lower transport and manual handling costs. I also think simpler fixing systems for both panel and wiring will continue to reduce labour costs. This technology of fixing PV direct to an old fashioned concrete tile doesn't address these cost objectives.
I remember when this was originally posted, and as it was then, my only concern with this product is that it still involves concrete, a product that is widely acknowledged to contribute significantly to world CO2 emissions. This isn't to say that I think perfect should be the enemy of good, but I do wonder if a similar take on a roof tile/solar combo could've been designed with a less carbon intensive footprint. Just because a product is cheap to produce, that doesn't necessarily mean it is eco-friendly. The (how) of production is just as important as the (why) of any given product; it's why procurement processes/contracts are starting to integrate this into the tendering process or in modern parlance, ESG.
Worth noting that the tiles are not specially manufactured as solar panels; They take already manufactured concrete roofing tile and glue PV panels to them. So in that sense, this is an improvement over traditional roofing since they would be using concrete tiles with or without the solar panels. That said you can also use terracotta tiles or asphalt shingle instead of concrete so I agree this might not be the absolute "greenest" option, but if you're going to be using concrete tile anyway...
@@peterbrown6453 I'm not good at maths and had to work at it to get the answer but I'm pretty sure it is in fact 3000% l even used a website percentage calculator. Apologies if I am wrong. The cost should be manafacturing costs plus profit, not comparison to the cost of something else
I have Solar Panels for 10 years now. 11.000 kWh Production a year since 2012. Heatpump 65 degrees Celsius, No Gas. No Energy Bill. Fast and Easy. Can be done around the world.
Good idea but when comparing the additional price of the solar he confuses people by comparing apples with pears ie one square metres and the other per tile. My impression is that the solar tiles are approx £300 per square metre compared to £10 for just tiles, just too expensive.
Here in the US we have such a strange dynamic of people. Those on the ideological right protest to be all about individualism, self sufficient and raising ones elf up by the bootstraps but when you mention to them that we should incentives as many homeowners, buildings and apartment buildings to incorporate solar and battery storage there's just so much resistance. It's the strangest thing to witness. They argue with you about electric cars, solar and wind and just think it's some nefarious trick by the federal government to adopt these things... But it's refreshing to regain my sanity to see people around the world take things seriously and are working on technology and solutions like this.
I love the idea of solar roof tiles but one thing slightly niggles, if they are connected as one array per elevation into an inverter (albeit at higher voltage due to parallel strings) does that not mean that any shadow on one tile will reduce the whole output of the elevation? With bigger panels you can get round this using micro inverters but that would not be practical here.
each tile has a bypass diode in the rear, to act as a power optimiser to ensure that all tiles in full si=unlight deliver full power, with shaded tiles not affecting the total output
@@chrishall409 in real life the bypass diode dont have the funcion, once the shadow is horizontal all line is dead..and in the video show horizontal shadow from row of tile above. the day efficency off the the tile will be half of the panels.
Would like to see more about how the modules are adhered to the tile and associated issues of weather proofing and therefore design life. Some tile cutter rig? Noise, dust and how long does it take? Don't get me wrong, it looks awesome and thanks for sharing it Fully Charged Show :) So glad new building regulations (June 2022) in the UK finally require new build domestic to have PV included and an EV charger, about time! Totally agree about big commercial buildings not having solar, it's bizarre, I guess lots are rented or leased? Short term thinking and lack of awareness, the payback on supermarket chillers and lights must be pretty quick even if only doing private wire and batteries (just self consumption) and not exporting to the grid.
Hi Dominic we supply the tiles direct from the factory with the module already mounted, as a new roofing product, rather than retro fitting onto existing roofs
@@chrishall409 it does seem a shame that a hole has to be drill through a perfectly good tile, therefore increasing the risk of water penetration, which is the primary purpose of a roof. Great work though on improving the likelihood of solar electricity being rolled out.
Yeah, NAH. You have to be crazy to rely on some perpetuum mobile glue to keep the rain water outside my house! One worker's mistake will cost me a fortune on top of this already premium fortune. Forget aesthetics, I'm not looking at my roof all day. I'd take the big panels just to have the peace of mind. 🤷♂✌ 1:16 Do YOU trust this funnily applied layer of sealant? Cause I sure don't.
This is a very good concept, but how long would the composite materials that seal the photocells from the UV from the sun, water ingress and general weathering last? Hopefully more than at least 30 years to make it viable to install. Only time can tell, really!
What's the efficiency loss due to the extra heading as you've lost the airflow. Also are these tiles rated for 40 years if your looking to swap these 1:1 for a normal roof.
But doesn't the "plonk on modules as an afterthought" not add ventilation/cooling for the panels? Or does the tile provide enough of a heatsink for that purpose? I also wonder if the overlap causes a slight shadow to appear which could drag the output down of the tile.
Give that a company in Australia is now developing cooling systems for solar panels to increase the efficiency (by quite a lot), your point is very valid!
so many connectors and bits, surely its just better to have massive roof tiles that are simply normal sized solar panels isntead of loads of little ones?
The issue here is I looked into solar panels, heat source pumps etc cost for my 2000 square feet house to install 32k yes 32k I will be pushing up the daisys before I ever get the cost back and I’m in my forties, and the person that worked out the cost stated I will be negative 1500 when it will need a complete re install
Not a good idea in Colorado, where golf ball sized hail storms happen every summer. Those hail storms cause a high percentage of home owners here to get new roofs almost annually. Our insurance rates will skyrocket if the insurance companies have to pay to replace all those solar panels annually also! The only way around that would be for the installers to put at least half inch thick plexiglass above the solar panels which would probably make them less efficient, especially when the dust from our dry climate clings to the plexiglass. By the way in my 40 years living here I have seen softball sized hail on 2 occasions.
Old mate forgot to mention the time it takes to drill the hole and glue the panel on each tile.. but decent idea. gotta wonder how water tight that panel is on that tile.
Great idea, but I would expect 60 plus years out of a concrete tiled roof, so when the solar degrades in 25/30/35 years you still have a roof but no solar.
I don't think conventional roofs last 60 years. My condo complex, built in 1997, just had its roof replaced two years ago, a lifespan of just 23 years for the original roof.
Solar roof tiles, aestetically, are great! But like the Tesla solar roof, have the same issue- cost. PV Panels, even as they have dropped significantly in cost over the last 20 years, are still expensive. To pay 3x that cost just for the aestetics is beyond what most people can afford. At least with PV panels, you can make a case for a pay back from that investment, albeit a long one- but not really for solar tiles. When their costs is equal to that of the cost of a new roof + PV panels, only then will they make sense for the vast majority of home owners, and only then on either new homes, or homes where the whole roof has to be replaced.
Is this really a good solution? Cutting a hole in the middle of the tile. How long will that stay watertight for? There must be a better solution out there. I saw something about solar shingles which looked interesting. Would be good to sop various options with pros and cons of each.
If you are getting "traditional" solar for an normal house. please specify Pigeon Wire Net round the edge . Some installers are not bothering & their customers are still getting Flocked ! ( cooing, rain of pigeon dung,damage to roof, possible fire risk). Which ever type, Solar PV is worth it both for long term finance & climate change & reducing dependence on energy companies. Literally taking back power!
This really should become a law that all new builds have to have this. The cost to major developers would be totally negligable due to the volumes they build in.
Connector on each and every tile seems like a bad design, a lot more modes to failure. If it's like Christmas tree lights 1 bad connector could take out the majority of the array
If it was a new roof then the cost of tiles should be factored in as well….unless his 50% premium included the cost of roof tiles as well. Brilliant product !
The big potential problem here, that was not addressed in Robert's interview, is, how is the problem of over-shading addressed? Lot's of properties have roofs which suffer over-shading from other properties, and especially from trees. For conventional solar panels, this reduces efficiency across the entire array, even in respect of those specific panels which are not over-shaded. The whole array only performs as well as the most over-shaded panel. The solution is to use panels which each have their own mini-inverter. SolarEdge is an example. With these panels, each panel performs to its best efficiency, regardless of over-shading. How do these solar tiles address this issue?
Hi, you are correct however, every tile has a bypass diode included, which combats the shading issues that traditional solar experiences. Laboratory testing in Vegas has shown that in low light, shaded conditions we can generate 50% more power than standard modules.
The idea of everyone using these tiles is a great idea however you can't just go on Ebay and buy them, I suspect you can only get them if you are a construction company, so though this is a good idea most people won't be able to get their hand son them. Like so many things DIY will have to wait until the tech trickles down to them. But that's probably why you don't see these things being used everywhere, you just can't get them.
This idea has existed as long as solar panels have been a main staple of the renewables industry. (30 years) There are a number of drawbacks to this design as well as increased costs hence these we're not that well accepted. If they can get the drawback sorted out these are a great idea.
Solar tiles is the next big step, I always thought it was a great idea since I saw the tesla tiles. If I had the money I'd love to get solar tiles and a battery, having kids and being home a lot power is used a lot and my pc probably draws half a power station lol. I get sun front and back so my roof would be great for these tiles. Now to win the lottory :(
Yeah it's a shame solar city never managed to get anywhere with there tiles. (to expensive and do many limitations due to the design choices) It's also a shame the classic installs we're so bad (contractor issues) that they burnt enough buildings down to have a class action lawsuit against them.
@@TheWebstaff Shame the investors were gulled into investing in "not quite ready for market" enterprise. That said some outfit will, eventually, marry off the roofing tech and the solar tech. R&D will get there eventually.
The math is interesting. The variable is the future price of electricity. I feel safe assuming that the price will increase. Then there is charging your car at home. The electricity price at home is much less than at a public charger. Added bonus is having electricity security. It does not take much to knock out the power grid. I cringe when I see new houses without solar roofs.
This is a move in the right direction, but what is really needed is for the government to put PV panels on every roof in the country, and a 8kwh battery in every home. Feed the generated electricity into the grid and give every household 10kwh of power a day, irrespective of whether they have a roof or not, for free. Anyone who already had panels should be allowed to keep them, but any feed in tariff they had been paid would be paid back as tax over a period of ten years. This tax would be waived for Green party voters, anyone suspected of having voted Conservative would pay double, Conservative party members who had inflicted either Johnson or Truss on us triple, whilst supported of UKIP or Reform would pay ten times, that is after having completed their one year prison sentence. BNP and EDL supporters would be transported to Rwanda, on the same plane as Suella Braverman.
I must say, I'm not keen on any roof solar since periodically they will need cleaning for maximum efficiency - with a cost attached. Put mine at ground level although I accept that isn't practical for everyone.
The drilled hole right in the middle of the roof tile concerns me a little. Over time, moisture can make it's way under the solar panel through the hole and under the roof. Same if the solar panel breaks. This area get's weakened alot. It would be more safe to put the electric connectors on the top area of the tile where they overlap.
The roof is an open air design. Under the panels (below the nailing strips) is water barrier membrane. Cement tile roofs like these aren't sealed. The tiles just lay on top of each other. If you are concerned about the water making it's way under the solar cell, you should be more concerned about the gaps between tiles since the tile above doesn't overlap the seam below by more than just the small overlap area where it's nailed 1:35. The tiles only have a small channel on the side under the adjacent tile for water to drip down. You can see it on the left side of the panel @ 1:24. But nothing is sealed, wind can blow water right under. edit: although under closer inspection at 0:45, it seems like they only have a vapor barrier under the nailing strips and not sure what's creating all the gaps underneath the strips. The waterproof membrane seems to be on the lower part of the roof, but the vapor barrier goes under it instead of over. This seems like a recipe for rot. It would be at least where I live. Maybe it works for the climate there. Edit 2: at 4:26 they seem to be just pushing down the vapor barrier to fish the wire under the strips, so that seems like there's nothing below but rafters. Maybe the entire attic is open with just the vapor barrier to catch the small drips that make it past the tiles with no decking at all.
@@scottkolaya2110 I'm familiar with this type of roof and I'm not concerned of a well proofed roof design. The water barrier normally stays dry and acts like a second security layer when the roof tiles leak because of damage or misalignment.The big difference between the overlapping gaps of this and any other roof of this type is that they are vertical in the way water runs. The solar panels are not full-area glued and most important their gaps run horizontal. This way the water can easily flow under right to the drilled hole which damages the waterproof system of this roof design.
I bought my brand new house in 2020, we bought the house off-plan and the builder had no option for solar to be installed while they built the house. I could not believe it, I wanted to have solar installed and I was told I could not because they do not provide it as an option. They grudgingly put in a car charger which I believe is actually not up to the task and will need to be removed and replaced with the correct wiring! The housing industry is broken.
They are asking the right questions. Not..."What is the best/highest quality roofing tile?" But..."What is the most common roofing tile?" Making something that is practical and affordable is much more important than making the best possible.
@@koitorob I agree with you, but I'm thinking from the standpoint of cost. I'd rather have something that is ok and affordable than amazing but way too expensive. I've got 5 kids to feed. 🙂
£27,000 for one roof - Dream on. (£30 x 900 tiles) This is a total non starter. It's 10 times more expensive than traditional panels, nobody in their right mind is going to do this. It's a real shame but it fails even the most basic sanity check. While we are doing a sanity check - 900 tiles on one roof needs 900 individual MC4 connectors. That is a big problem as those MC4 connectors do fail. According to the information given, one connection fault will disconnect 45 tiles. After a few years those 900 connectors will fail, fault finding those will be a common event and ridiculously time consuming.
Tremendous effort in the fight against co2, but we must do something about bottled co2 being fed into aquariums which increases plant growth, increases oxygenation which in turn improves water quality, a recent study has just been published highlighting local global warming in areas like lounges and other areas that have aquariums, this must be stopped now and bottled co2 banned.
Look up the percentage of CO2 output for a variety of sources and compare. Then look up where the CO2 is sourced from for bottled. It's a relatively tiny amount of worldwide release, and it was going to be in the atmosphere already, we just get use out of it first. You know that humans breathe out CO2 as well, yeah?
Anything that gets more solar on roofs has got to be good. I would like to see some sort of planning reg that says you must install a certain amount of solar on all new builds or pay into a 'infrastructure fund'

It's an impractical, overpriced pile of pants...!! And that's official.....!!!
Agree with you over failure of one cell. Resulting in efficiency drop on all of the solar units.
While I like the idea in principle, and it looks much better I do have a couple of issues.
1. (As mentioned by others) the hole in every tile and a small bead of adhesive to bond the cell to the tile is not going to last long or be 100% perfect for every tile. This means leaks.
2. Roof tiles life probably exceeds 50-60 years, solar panels probably 20 years or so before losing efficiency. And with this it's a new roof when the solar panels need replacing.
Great idea, however hasn’t the hole and sealant just put a potential leak path in to every roof tile? It’s just a case of when the sealant will give up and leak then you may have many many leaks! As an engineer that seems a fatal flaw in the system. Solve that and your on to a winner.
Leaks and dribbles aren't a problem. 🙂 Every roof in soggy, stormy Britain (your location may vary🌞!) has 'underfelt' - a tough, flexible, continuous, waterproof membrane to stop any wind-driven rain and snow that blows back up under the slates and tiles from entering the roof space.
Any water driven under the outer roof cladding then gathers on the waterproof membrane and runs down the roof UNDER the tiles, directly into the same gutter that collects the rain falling on the outside of the roof.
Even if tiles are cracked, holed or missing completely, a felted roof is still waterproof. The hard outer shell (concrete, slate, terracotta or stone) is really only there to protect the waterproof membrane underneath from mechanical and environmental damage (UV light, hailstones, gales, snow, ice, birds, reindeer, etc).
A modern thatched roof will also have the same type of waterproof membrane under the reeds.
@@EleanorPeterson "reindeer" love it 😁
@@EleanorPeterson Not strictly true, the felt (or these days breathable membrane) is only there to provide temporary weather resistance before the tiles are fitted, and after that the main function is to prevent wind uplift, and occasionally deal with fine wind driven snow. The tiles remain the sole waterproof covering, so any leakage is a serious problem if not dealt with immediately. It doesn't take long for felt underlay to degrade if a tile breaks or goes missing.
Then that is a major fault in building standards. Having the outer layer be the only waterproof barrier is ridiculous.
@@mikebarry229 That was my knowledge too, while the membrane will give some water resistance it’s not roofing felt anymore. I think it’s a simple fix, ensure the something covers the entire tile, actual PV would be daft given it get lapped, but surely some extra material extended to cover the tile, perhaps the electrical connections could go through the top then and avoid any hole drilling entirely on the tile?
They're no where near as efficient as panels at the moment though, I looked into these when I was looking at getting solar on my roof and standard panels were the better option. Might change in the future though
You've answered a question i was wondering about.
No, but they do provide an option that _might_ be approved for eg. listed buildings where panels would not be an option.
@@thomasfrederiksendk yes, agreed that would be a good application. I'm sure the efficiency will also improve over time, as there are a few areas on my roof that I'd like to cover with them when that happens
@@BSJWright I live in a low grade listed building, with restrictions on modifications to the outer shell only. Panels are a 100% no-go, but we might just get red ceramic tiles with solar built in approved if we ask nicely - and I’m hoping they’ll be much better when the roof is slated (pun intended) for replacement in 25 years.
@@thomasfrederiksendk
That's true. But, the economic justification for installing the solar system in the first place weakens when the efficiency goes down. If you can't get enough power to recoup the installation cost through electricity savings within a reasonable time period, it's not worth it.
The answer for the dynamic loading caused by external solar panels is to modify the roof design to take that loading into account before building. My own roof , SIPS, came with 22 pages of calculations to show it was suitable for solar panels, solar thermal and keeping the rain out and the wind away.
We need this product here in Australia! So many tiled roofs in Sydney alone that this would suit perfectly!
I don't think I've ever seen a flat roof tile like these is Australia.
@@rogerbrand6214 Yeah there isn't any tiles like that in Sydney. Shame. I wonder how the glue would go in Aussie heat aswell.
The maths just doesn't add up...
Each tile is 15w at a cost of £30 each.
Average 400w panel is around £200 these days.
400/15 = 27 tiles (rounded up) to output a similar amount
27 x £30 = £810 for the same amount of output.
Not to mention the surface area of 27 of these tiles would be far greater than a single panel.
It would be far cheaper and much more efficient to get a standard roof and then add the panels on top.
this was filmed a few years back and a repeat so would be interested in the updated pricing
He hit the nail on the head when he said It's A No Brainer.
Great new word: Solarize.
imagine having a bad connection in one of them . maybe they do 1 run of the tiles and then some sort of monitoring module. i would hate to check 600 connections :-)
As a sparky, that was my thought as well! Too many joints for me , every connection is a point of failure. F or me , I'll stick to my panels.
Gregg :-)
The best idea I've seen yet UK government should change the planning law and make this sort of thing compulsory.
Marley did solar roof tiles at least 15 years ago if not before, they were installed on Southampton university and had a live web page to view the results in 2004.
They stopped because of poor take up but now they are doing them again.
Probably poor uptake because it was too expensive then and is too expensive now.
@@tangerinestorm Definitely
Different products, first was in in tile replacement glass module, their new solar tile is a standard module laid in the roof in place of tiles, it is not a solar tile in the way that these are
Is this a re-upload? I'm sure I have seen this before.
It is .... I've seen it before too.
See pinned comment.
It's called recycling, take a video previously released years ago & re-release it via another channel.
It magically appears in someone suggested TH-cam list as a new video. Double ad revenue for the same product.
To be fair they do disclose this in a pinned comment as a "refreshed edit of a very popular release".
If the rows are connected in series what happens of you get a fault on one tile
I've got roof integrated PV panels. They are ordinary PV panels with a special mounting adapter made by a company called GSE. It's smarter looking than an "on-roof" system, and it dramatically reduces static load on the roof. It's been in operation for 2 years and has withstood Storm Arwen, Malik and Corrie without damage, and it's shed some of the worst torrential summer downpours I've seen without leakage.
This looks good, but the labour costs are much higher for installation and because of the number of individual elements and connections, the warranty callouts are likely to be higher than they would be for ordinary panels. There's also a complete lack of choice in this form factor, so warranty issues in the years to come are likely to be met with obsolescence issues, whereas standard sized panels will probably have plenty of replacement options to choose from.
Since the pandemic, I've been tracking the PV/Concrete tile price ratio. Prepandemic, it was £10/sq metre for concrete tiles, vs £50/sq metre for solar PV. So price ratio was about 5. Now it's £20/sq metre for concrete tiles, but £100/sq metre for solar PV. Price ratio is the same.
So personally, I think trending solar PV tech will focus on reducing rooftop costs. That means lighter rooftops which also benefit from lower transport and manual handling costs. I also think simpler fixing systems for both panel and wiring will continue to reduce labour costs. This technology of fixing PV direct to an old fashioned concrete tile doesn't address these cost objectives.
I’ve been waiting years for someone to do this!!! 💪🏻👍🏻
I remember when this was originally posted, and as it was then, my only concern with this product is that it still involves concrete, a product that is widely acknowledged to contribute significantly to world CO2 emissions. This isn't to say that I think perfect should be the enemy of good, but I do wonder if a similar take on a roof tile/solar combo could've been designed with a less carbon intensive footprint.
Just because a product is cheap to produce, that doesn't necessarily mean it is eco-friendly. The (how) of production is just as important as the (why) of any given product; it's why procurement processes/contracts are starting to integrate this into the tendering process or in modern parlance, ESG.
Worth noting that the tiles are not specially manufactured as solar panels; They take already manufactured concrete roofing tile and glue PV panels to them. So in that sense, this is an improvement over traditional roofing since they would be using concrete tiles with or without the solar panels.
That said you can also use terracotta tiles or asphalt shingle instead of concrete so I agree this might not be the absolute "greenest" option, but if you're going to be using concrete tile anyway...
@@Smidge204 Fair enough.
The problem with this technology is an increase of %3000 from a roof tile, to a roof tile with a solar panel stuck on, why.
You only do this if you need a new roof anyway.
300% not 3000. But the cost you should compare to is the cost of a new roof + install of a separate solar system.
@@peterbrown6453 I'm not good at maths and had to work at it to get the answer but I'm pretty sure it is in fact 3000% l even used a website percentage calculator. Apologies if I am wrong. The cost should be manafacturing costs plus profit, not comparison to the cost of something else
30£/tile instead of 1£, so 30x cost, or 3000%. 1£/tile seems cheap but maybe when you buy in serious bulk quantities.
@@zapfanzapfan ah, I meant to go back and listen, thought it was £10 and £30
this looks familiar. wasn't this in your Fully Charged Channel earlier this year or last?. Great idea. For countries that use solid tiles like this.
Looks familiar? Well that's tesla solar roof right there elon musk doing this for many years
I have Solar Panels for 10 years now. 11.000 kWh Production a year since 2012. Heatpump 65 degrees Celsius, No Gas. No Energy Bill. Fast and Easy. Can be done around the world.
v interesting,is the life span the same as rigid ? how easy is to find a faulty tile and it looks like its going to be a bugger to replace ?
Isn't this a re-issue of this video! I seem to remember watching it on Fully Charged over a year ago?
Good idea but when comparing the additional price of the solar he confuses people by comparing apples with pears ie one square metres and the other per tile. My impression is that the solar tiles are approx £300 per square metre compared to £10 for just tiles, just too expensive.
I have been enjoyed, so thank you for delivering.
Here in the US we have such a strange dynamic of people. Those on the ideological right protest to be all about individualism, self sufficient and raising ones elf up by the bootstraps but when you mention to them that we should incentives as many homeowners, buildings and apartment buildings to incorporate solar and battery storage there's just so much resistance. It's the strangest thing to witness. They argue with you about electric cars, solar and wind and just think it's some nefarious trick by the federal government to adopt these things... But it's refreshing to regain my sanity to see people around the world take things seriously and are working on technology and solutions like this.
I love the idea of solar roof tiles but one thing slightly niggles, if they are connected as one array per elevation into an inverter (albeit at higher voltage due to parallel strings) does that not mean that any shadow on one tile will reduce the whole output of the elevation? With bigger panels you can get round this using micro inverters but that would not be practical here.
Think you mean, Higher voltage due to "Series strings".
each tile has a bypass diode in the rear, to act as a power optimiser to ensure that all tiles in full si=unlight deliver full power, with shaded tiles not affecting the total output
@@chrishall409 in real life the bypass diode dont have the funcion, once the shadow is horizontal all line is dead..and in the video show horizontal shadow from row of tile above. the day efficency off the the tile will be half of the panels.
Hmm. £300 per 150w? Far too expensive.
I like this. There are so many good ideas how to go green its just great!
Would like to see more about how the modules are adhered to the tile and associated issues of weather proofing and therefore design life. Some tile cutter rig? Noise, dust and how long does it take? Don't get me wrong, it looks awesome and thanks for sharing it Fully Charged Show :)
So glad new building regulations (June 2022) in the UK finally require new build domestic to have PV included and an EV charger, about time!
Totally agree about big commercial buildings not having solar, it's bizarre, I guess lots are rented or leased? Short term thinking and lack of awareness, the payback on supermarket chillers and lights must be pretty quick even if only doing private wire and batteries (just self consumption) and not exporting to the grid.
Hi Dominic we supply the tiles direct from the factory with the module already mounted, as a new roofing product, rather than retro fitting onto existing roofs
@@chrishall409 it does seem a shame that a hole has to be drill through a perfectly good tile, therefore increasing the risk of water penetration, which is the primary purpose of a roof. Great work though on improving the likelihood of solar electricity being rolled out.
This is a good option for conservation areas where conventional solar panels would be hard to get through planning.
A no brainer if you've got more money than brains! I'll keep my panels thanks.
Yeah, NAH. You have to be crazy to rely on some perpetuum mobile glue to keep the rain water outside my house! One worker's mistake will cost me a fortune on top of this already premium fortune. Forget aesthetics, I'm not looking at my roof all day. I'd take the big panels just to have the peace of mind. 🤷♂✌
1:16 Do YOU trust this funnily applied layer of sealant? Cause I sure don't.
All house builders should have to use this kind of tech. Imagine if every house had these on.
It's a shame they didn't take into account the shadow at 1:54 ..
This is a very good concept, but how long would the composite materials that seal the photocells from the UV from the sun, water ingress and general weathering last? Hopefully more than at least 30 years to make it viable to install. Only time can tell, really!
What's the efficiency loss due to the extra heading as you've lost the airflow.
Also are these tiles rated for 40 years if your looking to swap these 1:1 for a normal roof.
But doesn't the "plonk on modules as an afterthought" not add ventilation/cooling for the panels? Or does the tile provide enough of a heatsink for that purpose?
I also wonder if the overlap causes a slight shadow to appear which could drag the output down of the tile.
Give that a company in Australia is now developing cooling systems for solar panels to increase the efficiency (by quite a lot), your point is very valid!
What is the work-life for these units> also if someone puts their boots on them while climbing on the roof cause problems with the tiles?
so many connectors and bits, surely its just better to have massive roof tiles that are simply normal sized solar panels isntead of loads of little ones?
The issue here is I looked into solar panels, heat source pumps etc cost for my 2000 square feet house to install 32k yes 32k I will be pushing up the daisys before I ever get the cost back and I’m in my forties, and the person that worked out the cost stated I will be negative 1500 when it will need a complete re install
Not a good idea in Colorado, where golf ball sized hail storms happen every summer. Those hail storms cause a high percentage of home owners here to get new roofs almost annually. Our insurance rates will skyrocket if the insurance companies have to pay to replace all those solar panels annually also! The only way around that would be for the installers to put at least half inch thick plexiglass above the solar panels which would probably make them less efficient, especially when the dust from our dry climate clings to the plexiglass. By the way in my 40 years living here I have seen softball sized hail on 2 occasions.
Old mate forgot to mention the time it takes to drill the hole and glue the panel on each tile.. but decent idea. gotta wonder how water tight that panel is on that tile.
Yes! Awesome idea!
Great idea, but I would expect 60 plus years out of a concrete tiled roof, so when the solar degrades in 25/30/35 years you still have a roof but no solar.
I don't think conventional roofs last 60 years. My condo complex, built in 1997, just had its roof replaced two years ago, a lifespan of just 23 years for the original roof.
@@ab-tf5fl I said sixty plus as my own are from the mid 1960s and still looking ok
Solar roof tiles, aestetically, are great! But like the Tesla solar roof, have the same issue- cost. PV Panels, even as they have dropped significantly in cost over the last 20 years, are still expensive. To pay 3x that cost just for the aestetics is beyond what most people can afford. At least with PV panels, you can make a case for a pay back from that investment, albeit a long one- but not really for solar tiles. When their costs is equal to that of the cost of a new roof + PV panels, only then will they make sense for the vast majority of home owners, and only then on either new homes, or homes where the whole roof has to be replaced.
Is this really a good solution? Cutting a hole in the middle of the tile. How long will that stay watertight for?
There must be a better solution out there. I saw something about solar shingles which looked interesting. Would be good to sop various options with pros and cons of each.
The way to go!!!
This needs grants to help get the cost down. And planning to get house builders to install solar tiles at reasonable cost compared to panels.
Thank you.
Didn't Dan cover this in a previous episode of Fully Charged? Love this solution though over standard solar panels, 13kW is a decent system.
I'm glad you asked this question, I thought I was experiencing deja-vu
If you are getting "traditional" solar for an normal house. please specify Pigeon Wire Net round the edge . Some installers are not bothering & their customers are still getting Flocked ! ( cooing, rain of pigeon dung,damage to roof, possible fire risk). Which ever type, Solar PV is worth it both for long term finance & climate change & reducing dependence on energy companies. Literally taking back power!
This really should become a law that all new builds have to have this. The cost to major developers would be totally negligable due to the volumes they build in.
Building codes in appropriate sunny areas should make solar mandatory.
Informative & clear 😊👍
Connector on each and every tile seems like a bad design, a lot more modes to failure. If it's like Christmas tree lights 1 bad connector could take out the majority of the array
What about when there are issues, would be paying the roof up to diagnose and fix an issue...
Excellent show
If it was a new roof then the cost of tiles should be factored in as well….unless his 50% premium included the cost of roof tiles as well. Brilliant product !
what do you do when the roof pitch, fall or weather conditions demands that you have a grater overlap?
Thats great, I like it.
How much it will cost a roof of a house around 100m2 surface floor
The big potential problem here, that was not addressed in Robert's interview, is, how is the problem of over-shading addressed?
Lot's of properties have roofs which suffer over-shading from other properties, and especially from trees. For conventional solar panels, this reduces efficiency across the entire array, even in respect of those specific panels which are not over-shaded. The whole array only performs as well as the most over-shaded panel.
The solution is to use panels which each have their own mini-inverter. SolarEdge is an example. With these panels, each panel performs to its best efficiency, regardless of over-shading.
How do these solar tiles address this issue?
Hi, you are correct however, every tile has a bypass diode included, which combats the shading issues that traditional solar experiences. Laboratory testing in Vegas has shown that in low light, shaded conditions we can generate 50% more power than standard modules.
We will be self building and putting on a solar roof, but using bespoke nulock roofing tiles that are half the weight of normal tiles
I love everything about this, but I dont get why people dislike the regular solar panel asthetic. Like, whats wrong with it? Looks dope.
The date shows 'today', but I remember seeing this before.
great video
The idea of everyone using these tiles is a great idea however you can't just go on Ebay and buy them, I suspect you can only get them if you are a construction company, so though this is a good idea most people won't be able to get their hand son them.
Like so many things DIY will have to wait until the tech trickles down to them.
But that's probably why you don't see these things being used everywhere, you just can't get them.
Great episode! One question though: I’m constantly told pv US much more efficient if cooled by airflow. Is this a different system? Thanks.
Absolutely ridiculous mark-up. Too greedy. Shameful.
Genius! I’d like to know why this wasn’t thought of 5 years ago, and if it was, what prohibited its implementation.
This idea has existed as long as solar panels have been a main staple of the renewables industry. (30 years)
There are a number of drawbacks to this design as well as increased costs hence these we're not that well accepted.
If they can get the drawback sorted out these are a great idea.
isnt that some old episode ?
What's the difference between their solar roof system and Telsa solar roof system?
This one ships!
We have been in production since 2011, Tesla have just withdrawn version 3 due to causing fires!
Solar tiles is the next big step, I always thought it was a great idea since I saw the tesla tiles. If I had the money I'd love to get solar tiles and a battery, having kids and being home a lot power is used a lot and my pc probably draws half a power station lol. I get sun front and back so my roof would be great for these tiles. Now to win the lottory :(
Architects have started to use solar wall panels to avoid the issues with aesthetic. More on "Construction Index" pages if arsed.
Yeah it's a shame solar city never managed to get anywhere with there tiles. (to expensive and do many limitations due to the design choices)
It's also a shame the classic installs we're so bad (contractor issues) that they burnt enough buildings down to have a class action lawsuit against them.
@@TheWebstaff
Shame the investors were gulled into investing in "not quite ready for market" enterprise.
That said some outfit will, eventually, marry off the roofing tech and the solar tech.
R&D will get there eventually.
The math is interesting. The variable is the future price of electricity. I feel safe assuming that the price will increase. Then there is charging your car at home. The electricity price at home is much less than at a public charger. Added bonus is having electricity security. It does not take much to knock out the power grid. I cringe when I see new houses without solar roofs.
This is a move in the right direction, but what is really needed is for the government to put PV panels on every roof in the country, and a 8kwh battery in every home. Feed the generated electricity into the grid and give every household 10kwh of power a day, irrespective of whether they have a roof or not, for free. Anyone who already had panels should be allowed to keep them, but any feed in tariff they had been paid would be paid back as tax over a period of ten years. This tax would be waived for Green party voters, anyone suspected of having voted Conservative would pay double, Conservative party members who had inflicted either Johnson or Truss on us triple, whilst supported of UKIP or Reform would pay ten times, that is after having completed their one year prison sentence. BNP and EDL supporters would be transported to Rwanda, on the same plane as Suella Braverman.
I must say, I'm not keen on any roof solar since periodically they will need cleaning for maximum efficiency - with a cost attached. Put mine at ground level although I accept that isn't practical for everyone.
Fill the roofs before using up farmland for solar.
The drilled hole right in the middle of the roof tile concerns me a little. Over time, moisture can make it's way under the solar panel through the hole and under the roof. Same if the solar panel breaks. This area get's weakened alot. It would be more safe to put the electric connectors on the top area of the tile where they overlap.
The roof is an open air design. Under the panels (below the nailing strips) is water barrier membrane. Cement tile roofs like these aren't sealed. The tiles just lay on top of each other. If you are concerned about the water making it's way under the solar cell, you should be more concerned about the gaps between tiles since the tile above doesn't overlap the seam below by more than just the small overlap area where it's nailed 1:35. The tiles only have a small channel on the side under the adjacent tile for water to drip down. You can see it on the left side of the panel @ 1:24. But nothing is sealed, wind can blow water right under. edit: although under closer inspection at 0:45, it seems like they only have a vapor barrier under the nailing strips and not sure what's creating all the gaps underneath the strips. The waterproof membrane seems to be on the lower part of the roof, but the vapor barrier goes under it instead of over. This seems like a recipe for rot. It would be at least where I live. Maybe it works for the climate there. Edit 2: at 4:26 they seem to be just pushing down the vapor barrier to fish the wire under the strips, so that seems like there's nothing below but rafters. Maybe the entire attic is open with just the vapor barrier to catch the small drips that make it past the tiles with no decking at all.
@@scottkolaya2110 I'm familiar with this type of roof and I'm not concerned of a well proofed roof design. The water barrier normally stays dry and acts like a second security layer when the roof tiles leak because of damage or misalignment.The big difference between the overlapping gaps of this and any other roof of this type is that they are vertical in the way water runs. The solar panels are not full-area glued and most important their gaps run horizontal. This way the water can easily flow under right to the drilled hole which damages the waterproof system of this roof design.
I bought my brand new house in 2020, we bought the house off-plan and the builder had no option for solar to be installed while they built the house. I could not believe it, I wanted to have solar installed and I was told I could not because they do not provide it as an option. They grudgingly put in a car charger which I believe is actually not up to the task and will need to be removed and replaced with the correct wiring! The housing industry is broken.
Is it just me or is this the same video/story that was on the channel a year or two ago?
They are asking the right questions. Not..."What is the best/highest quality roofing tile?" But..."What is the most common roofing tile?" Making something that is practical and affordable is much more important than making the best possible.
I disagree. It should be 'what is the most efficient solar panel' then 'what size should we make it to fit the most common sized roofing tile'?
@@koitorob I agree with you, but I'm thinking from the standpoint of cost. I'd rather have something that is ok and affordable than amazing but way too expensive. I've got 5 kids to feed. 🙂
*sigh* I own a semi detached with East, West, North facing roof sides. Significant tree cover too. It would just never be worth it.
That's a lot of collective resistance from all those plugs.
Maintenance on faulty panels would be a nightmare. No thanks.
Concept is fine, price is crazy. In roof solar panels are a more cost effective option.
I am worried about all the individual connections
what a great idea
It should be government legislation that all newly built houses incorporate a solar power roof
0:16 i wouldn't call it invisible. looks like to me that you have two different roof tiles.
from ground level you cant see the difference
£27,000 for one roof - Dream on. (£30 x 900 tiles) This is a total non starter. It's 10 times more expensive than traditional panels, nobody in their right mind is going to do this. It's a real shame but it fails even the most basic sanity check. While we are doing a sanity check - 900 tiles on one roof needs 900 individual MC4 connectors. That is a big problem as those MC4 connectors do fail. According to the information given, one connection fault will disconnect 45 tiles. After a few years those 900 connectors will fail, fault finding those will be a common event and ridiculously time consuming.
Tremendous effort in the fight against co2, but we must do something about bottled co2 being fed into aquariums which increases plant growth, increases oxygenation which in turn improves water quality, a recent study has just been published highlighting local global warming in areas like lounges and other areas that have aquariums, this must be stopped now and bottled co2 banned.
Look up the percentage of CO2 output for a variety of sources and compare. Then look up where the CO2 is sourced from for bottled. It's a relatively tiny amount of worldwide release, and it was going to be in the atmosphere already, we just get use out of it first.
You know that humans breathe out CO2 as well, yeah?

Anything that gets more solar on roofs has got to be good. I would like to see some sort of planning reg that says you must install a certain amount of solar on all new builds or pay into a 'infrastructure fund'
This was an article a couple of years ago! Has nothing advanced since then?
