Thanks very much for your latest video on the Future of Solar. It’s good, and very interesting to see this presented all in one place . Keep up the great work.
My great concern with perovskite PV panels is the lead inside them. If they aren't properly recycled, there could be serious ground water lead poisoning!
Tesla were reluctant to allow bi directional because of cycling of their old style battery chemistry AND they obviously didn't want to effect sales of their powerwalls. Perhaps they'll change, but who knows what Elon is currently thinking? BYD cars are all able to supply V2L, so presumably they can be easily adapted to bi directional? MG has started offering a lifetime warranty on their batteries, so excessive cycling is presumably not an issue for their technology.
lets say a battery is 60kwh and you drive normal mileage you probably have to charge once a week ? well say you WFH and use the car not a lot (as me) then 60kwh could power the house for like 4/5 days so cycling is not that much more ? the bigger positive is to have a virtual power grid where you charge up overnight and then release at the day during peak time. given most homes are only 2 phase and can only charge/release max 7kwh then this is not going to overload is it ?

Hi, When you were talking about v2h, you mentioned some manufacturers readying products to allow people (me!) to use my car to power my home. My question is:- Do you think there will be a possibility that cars that don't support bidirectional charging (like my 2022 Kona) will get an aftermarket addition to allow this.

There are two ways of doing this - inverter in the car, connected to the grid via a 'standard' type2 charge point - which is after all just a contactor with some logic control. Or you have the inverter in the charge point and connect it directly to the battery. The former seems sensible because loads of cars have V2L now but you then need to worry about syncing this up with the grid frequency and being subject to various regulatory bodies across the world - do car manufacturers want to do that? The SolarEdge unit that's been announced is the latter type - it connects to the car via CCS, so it's essentially connected directly to the battery. This makes the charge point hardware much more complex and expensive but it means it can be bidirectional. All that's needed is to pursuade the car to keep the battery contactor closed. It's likely this will probably require collaboration between SolarEdge, and similar products, and the car manufacturers but I can see that you could just lie to the car about what's going on. It isn't what the charging firmware is designed for, so it may be the car will consider the charger faulty and disconnect.... but either way, it would be interesting to see if this can allow older cars like my 2020 Niro to become a home battery.

The weirdest place I've seen solar panels installed...... wait for it... Solar freaking roadways!!!!!!!!!!!!!!!!!!! With the number of roofs we shouldn't be touching roads until we've covered every roof, bus stops, treeless parking heat island, etc. I think the solar roof tiles are going to be interesting.
8:20 - those 580 Wp panels save about 10% of the cost of the underconstruction, the amount of profiles and clamps needed on the roof Also more or less 10 to 15% cheaper based of price per kWp installed. We have build a 25 kWp array on 2 roofs and with 550 Wp and 580 Wp you need lot less panels which means less rails cause these are all 110 cm or 113 cm wide like those 450 Wp panels, only 50 cm taller. And we have already seen next gen of 660 Wp which are even 25 cm longer so from 225 cm those jumped to 250 cm. WIth 30 kg weight they are not easy to carry around but 60 x 400 Wp or 40 x 600 Wp is making a huge difference costwise at the end, when you can not save money elsewhere. Our average costs for a panel mounting is 40€ and 60x means 2400€ or 1600€ for just 40 panels. If you put on top 25 kWp x 150€ or 15% less like 128€ then you save 22€ x 25 per kWp or 550€ on top, in tota 2100€ for 25 kWp array. BUT, and that can be a big but for some: Those bigger panels (once built for our agro PV fields) do not fit always quite well. If they are too tall you might loose 1 row of panels or you have to mount those horizontally. If you would have smallest tiles you could perfectly cover a roof into all edges and corners, but with bigger ones you might endup with areas you can not use with such sizes . There will be another step to look for a smaller size to check if you can get more kWp installed on your roof using a smaller panel size. And then smaller could be better if you are in need of such an amount of kWp that every spot of the roof has to be covered by panels. Perovskite are a topic here in germany for almost 2 years and we bet that they will be the future due to the current state of research and progress but they suffer from new production methods required, more faulty units in the early batches and all the small details till that will become the new standard. Mono and poly was an open battle for years, then we saw halfcell appearing and what not tilll those became the standard. And perovskite is on top of the list due to the high leap that tech has shown up to over 28% in serial production compared to 21% or 22% . The current production is progressing steadily but rather slowly and not much room for improvement except the tiny steps every 6 - 12 months with 30 Wp more per panel of the same size.
3:30 roof mounting bi-facial solar panels has to be a complete waste of time - what amount of reflected light is there underneath a solar panel that is six inches or less away from roof tiles that are in the shade? For ground mounting, they are a good idea, but on roofs, why waste the money on more expensive bi-facials, which simply cannot be getting any light from underneath?
I never did care much about microinverters, diodes have been there for some time but generally only one per raw ( doubled that in half-cells modules) and that works pretty well, not sure if having more diodes could potentially lead to more issues if one or more decides to go on the blink 🤔
5:10 "This for us has been standard practice"... in order to make as much money as possible, because optimisers and micro inverters don't increase solar panel output sufficiently to justify the cost and also complications they add to your system...
Interessting concept with that invisible solarcells might be great for older historical buildings to keep the original apperances, but for "normal" houses i still think the roof is the best place, since it is dead space anyway which you cannot really use otherwise
If everybody had about a 7 to 10 KW solar system on their house. With battery backup and bi -directional. Base load production would go to about 30%. And they should charge accordingly.
Tesla, Volvo, Citroen, BYD and other EVs are already capable for DC bidirection charging however they officially do not support it yet. High voltage DC batteries and high voltage DC inverters have been around for several years. Exactly such inverter what you need and a small "raspberry pi" control circuit that telling the car over the charging port that you are discharging.
Hopefully on the ev side they can allow the dc to flow out, sigenergy will allow the solar to battery, then dc to dc connection to the ev, and inverter to grid in the one unit. Getting a quote for the Signstor system.
And in mkaes so much solar power with the panels on the train and the station roofs that they sell the surplus to the local grid! :D Byron Bay is a communnity very much in to that sort of thing! :)
ah im also getting 15000Wp of bifacial solar panels on my roof. Great to hear about the lower light conditions. Im not in a country that really "shines" bright of a lot of light all the time.
Two questions - (1) what are the payback times for these products and (2) how well do they work when there's no/little sunlight? My BiL has a 4kW solar PV system and he measures ~8kW/WEEK in October, ~4kW/WEEK in November, ~1kW/WEEK in December, 2kW/WEEK in January and 5kW/WEEK in February. So, in the FIVE months where it would be useful to have Solar energy he gets 'diddly squat'.
Tahnks for all this information. I just have one question i still could not figure out...is it a problem when you mount solar panels on a roof terrass behind glass railing? Does this have a negative effekt? The glass railing is transparent.
Are there actually any usable non-vendor locked V2H solutions that work with most EVs yet? The only things I've seen actually usable are Ford and GM have something that you can actually buy but only works with their own stuff which is completely useless in my books.
I actually really enjoyed this video - renewable tech on the horizon from the point of view of someone with their feet on the ground, installing systems, not some opinionated guy in a bedroom who has spent 10 minutes on Google.
V2H /G is all very well but the cars gzve been around to do it for years. It's the grid that's the issue and the closed energy supply market!! Can't even get an export limit above 7kw in the north! Been contemplating V2H then ditching the grid entirely.
Almost any electric car can provide power through the CCS DC port(for V2G or V2H). Such a possibility is already included in the management protocol. But the manufacturers have not yet announced this possibility, they are probably really worried about the warranty on the battery. Specialists who understand the protocols can easily implement this, of course not officially. You can also use Tesla car batteries and high-voltage inverters to get cheap storage, 60 kWh or more in volume. 100kWh for 10k dollars, an interesting offer)))
The appropriate protocol being in the spec does not mean that the capability is in most electric vehicles. Manufacturers need to install the extra hardware to support the outgoing DC power. This is why only a few models of each manufacturer are listed as supporting V2H/G. And if manufacturers are worried about the warranty, why do both Ford and GM provide the capability in their pickup trucks (in North America).
Hey Jordan, home come the change in format? Will you be getting back to the old style of videos where you're out doing installs, trouble shooting, repairs? Or do we go watch Cory for that content?
Can beleive how far uk behind Had enphase plus full glass panels no edge Bi facial for ages Done roof tile solar with monier solar roof tiles All in little old nz
Sadly, our government here (no matter who is in power) seems to view investment in new technology as a headline-grabber instead of something that might actually help people, so they do grants for a while, it's often just a scam dressed up to be appealing, & then they stop supporting it. It's incredibly frustrating.
I doubt that these side or roof tiles will be as effizient as a normal solar panel. Micro inverters are not really there to be optimizer alone. Perovskite Panels are still not available biggest thing in the game is Oxford PV, but currently there things are not produced at all even though they say they will start production every year.
Would love to know the pricing for the industrial sized battery storage compared with the likes of a Tesla Power wall (or equivalent) from a price per kwh from a large domestic setup with maybe 3 Power walls? Or should we just all buy an EV with the biggest battery possible and with a V2G/H option? Maybe buy a 2nd car and leave in the garage and use that as your battery storage?
We really need EVs or BVs, with selfplug-in V2G, V2Home, V2Building. BVs oversized battery makes the home battery look pathetic. 😊 BVs oversized battery has FREE storage capacity every day, year in and year out. Vehicles are parked 23hrs every day. Vehicles drive building to building. Every building carpark space will have a $60 wall outlet for the selfparking Vehicles Selfplug-in. 😮😊😊😊😊
all very true but I would want my car to have a good amount of charge for when i need it. I never leave my petrol tank empty. however buying a cheap Nissan Leaf if you have enough drive space for an extra car. leaf just to use it as a home battery could be an economical way to add a large home battery
@steveevans1247 Good comment. I can easily see rapid chargers on the main roads and at corner stores when needed. I think that the vehicle computer could be programmed to have enough for the next drive. The long drive or the daily drive. This feature would allow savings on electricity supply, gas supply, and petrol supply. Savings are instantaneous tax-free money in the bank. Hahaha 👍 Hahaha Also, the grid could supply to new industries and take your excess rooftop electricity. So you can remain grid connected as a backup. In a warming world rooftop, PV panels shade rooftops and help the air-conditioning load. When the sunshines grid cashflow from customers with rooftop PV crashes.
I don't think that there's much future in using a car battery as a battery for your house - what you're doing there is adding unnecessary cycles to your car, which even with LiFePO4 batteries is a really questionable thing to do to a car battery, given they're not exactly hot swappable (in fact they're normally built into the chassis). A wall battery that you will probably want to swap out anyway after a certain amount of time doesn't have the same issues. Maybe in an emergency, but to build all that tech for an emergency is super questionable - and most cars aren't LiFePO4 either. Vehicle manufacturers don't care because it isn't their battery when you drive the car away, it's an easy thing to shove into warranty terms that it isn't their problem on page 673826. Cars aren't disposable, you're going to destroy its secondary market value because everybody is going to be able to see the data.
Really? Average daily mileage in the UK is less than 30 miles, thats about 6 or 7kWh of energy. Using another 20 kWh of the stored energy would still only be using around 30% of the stored energy. What's more, the average charge/discharge rates for home usage are absolutely trivial - 2kWh of domestic load would be barely 0.03C not stressing the battery at all.
With v2h charging solutions, will a solution like sigenergy work with any car? Or will sig energy need to work with the car company to work out the push and pull of electricity. To get the right profiles... One of the things with car manufacturers solutions was, what happens if i change my car. Will there solution need replacing?
Really interesting and I think in the future Solar will just be a no brainer, but with so much new tech on the horizon I would currently not touch solar with a barge pole as it would likely make sense to change the panels or setup to a more efficient setup before the payback period making current investment not worth it..
There have been a couple of trials of ChaDeMO V2G - it's always supported it but since they lost the format war hasn't really had any more development. Indra did one, but the hardware is almost impossible to get hold of.
@@JamesScholesUK I was meant to be on one of those trials but at last minute fell through but only to charger manufactures indra and wall box made the chargers. Wallbox have said they will only make CCS V2G chargers going forward and Indra won't sell you a V2G chargers currently and since they were acquired by Gulf may never.
I’d heard the VW ID4 has a bidirectional charge capability (well, it has a bidirectional menu in it’s in-car interface) With 77kwh usable capacity, this would be a good home back-up power option, if indeed V2H capabilities with Sigenergy or Solaredge systems.
As the main problem with EV's is the range I have no idea why you would decrease the range of a car to power your home. The other issue with EV's is that secondhand values are falling through the floor, never mind the warranty on a battery, if I know that a battery has been recycled even more through bi-directional charging then I am hardly likely to think that there is secondhand value in buying such a car.
All Volkswagen ID range with the bigger batterys 80kw now offer bi-directional charging, I've got a 2-year lease and I would love to claim an extra 2 grand exporting the battery 💵👍
Optimizers will not go away, but Microinverters will stop existing. Because everything will go MORE AND MORE DC. So why directly put DC to AC? you have to postpone that.... therefore Optimizers which are DC/DC converters with MPPT will stay even with better shading panels. If you install microinverters it's just a short cut, lazy and will drive your customer up with higher cost to change it later on in the future. (which you probably want right?? ;) )
Has anyone else noticed that this has become the Jordan show I subscribed to this channel to see the quality installs that all of the guys did, and not just a one person show
I don't see anyone analyzing the impact of having batteries for storing your electricity and solar panels on your home, to our health. There have to be electromagnetic fields, I've only read some people's comments about getting sick from riding in Teslas
Optimisers and diodes don’t do the same thing, surely? Optimisers should behave like an MPPT, optimising the panel output voltage to match the load and panel, whereas the diodes only eliminate the problem of partial shading knocking out a whole string of cells within a panel. Isn’t that the case?
The problem here is that Artisan is clueless with regards to anything to do with solar and battery. Just another TH-cam grifter like the mentioned Matt Ferrel.
Fascinating video. Just taken delivery of my new Hyundai Kona Electric which apart from being a great upgrade on my previous one - it also comes with the technology to work provide energy to the home. They really have got it together. Well done motability for encouraging us to buy electric cars.
what happened to all the "on the job" videos you used to produce? i take it those are no longer part of your business model due to having to make several people redundant a while ago?
I don’t think electric cars are the future mate.. you have got to look at the Japanese they are looking at a cleaner fuel . The solar roof tiles look good! Yes definitely got to go towards cleaner energy for sure!
That cleaner fuel really needs to be able to utilise existing distribution infrastructure (Ie a liquid fuel that can be pumped like petrol) or the implementation costs will be too high. To date, all efforts at synthetic liquid fuels are great in the laboratory. But physically just can’t be scaled up to meet current worldwide demand for petroleum based fuels. Meaning for the foreseeable future, electricity is it.
Yeah I have have 3 cars soon to be 4 how am I going to charge them mate with out paying loads of money? When they are trying to go all electric in houses we just haven’t got the power captain!
@@justinrowe3346 if you're telling me you need to charge 4 vehicles to 100% every night (say 250kWh a day) of every month, you might have an issue on single-phase but that's unlikely......with 3-phase and load balancing it could be done but, come on, how many miles are the household doing? we run 2 cars now and have for several years and it's unbelievably cheap, we average 1.4p a mile which is a fraction of cost of petrol. If you're serious about this question, get in touch and I'll help you...
@@justinrowe3346 The average vehicle only travels ~40Km a day. With battery ranges of 400km + a 4 car household could rotationally charge each car every 4th day without any issues. Charging time from a standard power outlet to cover 160km is ~10 hours. Higher amperage outlets can reduce that time down to ~4 hours. Which can be done in the wee small hours while electricity demand is much lower, so plenty of spare capacity to accommodate the charging power. And of course supercharges can be used as well if necessary. So there you go Justin, you can have a 4 car EV household no problem. In so far as the whole grid’s ability to cope, even when every car on the road is an EV total electric demand will only increase by ~15%. And as long as most charging occurs outside of peak consumption periods there is generally plenty of headroom in the grid infrastructure. Though electricity authorities are planning to increase grid capacity over the next 30-40 years to match the increase of EVs.
Sounds like a pain in the ass to me mate and a lot of money bud how much is it to replace a battery on a car ? That’s why people are coming away from electric cars because they are not convenient !
Have you ever used Hone panels? I ask because all the new products have the same problem - they're brilliant in the summer but weak in the winter. In other words, exactly the wrong way around for the average consumer's needs. Hone make big claims and post data to 'prove' their value (high outputs in winter) but I'm suspicious when I can find no happy customers here or experts such as yourself who have used them.
Anyone who thinks that highly diffuse and intermittent energy-generating sun boards and wind veins will ever make a real difference to the net zero bullshit is a halfwit. In a first-world country, anything that generates at about one-third of installed capacity and which is used for heating or A/C is useless unless you spend a mega fortune on your renewable array and battery storage. Moreover, bi-directional EV charging is also bullshit. Batteries take more energy to charge than they give out. To suggest that they can be used as backup power for anything more than light general services (LED lighting, TV, computer etc) in your home and then powering your car might be reasonable short term, anything more than that (heating, cooling) is more nonsense.
Invisible panels, no one cares. Sides of buildings are probably rotten places, always half in shadow, especially in cities to put panels on anyway. Roof tiles shown look rubbish, perhaps industrial rooves? Perovskite too small a gain and still not actually here for some time. Maybe in a decade. Vehicles, we may well not be owning them soon as they will be on demand and driverless. So the use period may turn out short.

WIth 30 kg weight they are not easy to carry around but 60 x 400 Wp or 40 x 600 Wp is making a huge difference costwise at the end, when you can not save money elsewhere.
Our average costs for a panel mounting is 40€ and 60x means 2400€ or 1600€ for just 40 panels. If you put on top 25 kWp x 150€ or 15% less like 128€ then you save 22€ x 25 per kWp or 550€ on top, in tota 2100€ for 25 kWp array.
BUT, and that can be a big but for some: Those bigger panels (once built for our agro PV fields) do not fit always quite well. If they are too tall you might loose 1 row of panels or you have to mount those horizontally. If you would have smallest tiles you could perfectly cover a roof into all edges and corners, but with bigger ones you might endup with areas you can not use with such sizes .
There will be another step to look for a smaller size to check if you can get more kWp installed on your roof using a smaller panel size. And then smaller could be better if you are in need of such an amount of kWp that every spot of the roof has to be covered by panels.
Perovskite are a topic here in germany for almost 2 years and we bet that they will be the future due to the current state of research and progress but they suffer from new production methods required, more faulty units in the early batches and all the small details till that will become the new standard. Mono and poly was an open battle for years, then we saw halfcell appearing and what not tilll those became the standard. And perovskite is on top of the list due to the high leap that tech has shown up to over 28% in serial production compared to 21% or 22% . The current production is progressing steadily but rather slowly and not much room for improvement except the tiny steps every 6 - 12 months with 30 Wp more per panel of the same size.
3:30 roof mounting bi-facial solar panels has to be a complete waste of time - what amount of reflected light is there underneath a solar panel that is six inches or less away from roof tiles that are in the shade? For ground mounting, they are a good idea, but on roofs, why waste the money on more expensive bi-facials, which simply cannot be getting any light from underneath?
My friend had a solar panel fence, only because it was half the price of fence panels 😮 who knew 😊
Its mad isn't it!
but are these harder to clean and resist power-washing roofs? How would the grime settle over the years?
I never did care much about microinverters, diodes have been there for some time but generally only one per raw ( doubled that in half-cells modules) and that works pretty well, not sure if having more diodes could potentially lead to more issues if one or more decides to go on the blink 🤔
5:10 "This for us has been standard practice"... in order to make as much money as possible, because optimisers and micro inverters don't increase solar panel output sufficiently to justify the cost and also complications they add to your system...
Interessting concept with that invisible solarcells might be great for older historical buildings to keep the original apperances, but for "normal" houses i still think the roof is the best place, since it is dead space anyway which you cannot really use otherwise
The 'invisible' solarcells aren't actually invisible.
If everybody had about a 7 to 10 KW solar system on their house. With battery backup and bi -directional.
Base load production would go to about 30%. And they should charge accordingly.
Tesla, Volvo, Citroen, BYD and other EVs are already capable for DC bidirection charging however they officially do not support it yet. High voltage DC batteries and high voltage DC inverters have been around for several years. Exactly such inverter what you need and a small "raspberry pi" control circuit that telling the car over the charging port that you are discharging.
Hopefully on the ev side they can allow the dc to flow out, sigenergy will allow the solar to battery, then dc to dc connection to the ev, and inverter to grid in the one unit. Getting a quote for the Signstor system.
Weirdest place seen solar panels was on top of a train carriage at Byron Bay in nsw Australia
@miesvanderlippe9017 flat level ground so no regen needed but has no hvac as old carriages
There is a train to Byron Bay that is ENTIRELY solar powered - maybe its that one - its a converted old diesel unit :)
And in mkaes so much solar power with the panels on the train and the station roofs that they sell the surplus to the local grid! :D Byron Bay is a communnity very much in to that sort of thing! :)
I'd not do bi-charging with NMC tech as the cycles are very low. LFP i think could be done but dunno if that is by the cable a good choice.
There was a real perovskite-tandem module in munich at the Oxford PV booth.
Our bifacials have performed well in lower light conditions over the last 2 or 3 years. 36 degrees south latitude. JA Solar JAM60D10.
ah im also getting 15000Wp of bifacial solar panels on my roof. Great to hear about the lower light conditions. Im not in a country that really "shines" bright of a lot of light all the time.
Yes, but HOW MUCH is "well"? Meaningless statement. Are they performing BETTER than normal solar panels?
@@johnthomas338👆this! Without stats it's meaningless
Two questions - (1) what are the payback times for these products and (2) how well do they work when there's no/little sunlight? My BiL has a 4kW solar PV system and he measures ~8kW/WEEK in October, ~4kW/WEEK in November, ~1kW/WEEK in December, 2kW/WEEK in January and 5kW/WEEK in February. So, in the FIVE months where it would be useful to have Solar energy he gets 'diddly squat'.
Yep, I have a fairly new 5.2 kWh peak system and in the winter months it’s pretty much useless.
Tahnks for all this information. I just have one question i still could not figure out...is it a problem when you mount solar panels on a roof terrass behind glass railing? Does this have a negative effekt? The glass railing is transparent.
Are there actually any usable non-vendor locked V2H solutions that work with most EVs yet? The only things I've seen actually usable are Ford and GM have something that you can actually buy but only works with their own stuff which is completely useless in my books.
Not yet I think they are all locking their systems down at the moment but once one opens up they all will I think…
I actually really enjoyed this video - renewable tech on the horizon from the point of view of someone with their feet on the ground, installing systems, not some opinionated guy in a bedroom who has spent 10 minutes on Google.
Haha thanks
Essentially, they created SD-WAN for the solar cells themselves based on the grid density. Not bad.
Great information thank you
2:00 What is the cost per kW for these panels? I bet they are ridiculously expensive and therefore non-viable.
I think mini magnifiers built into the cells is next to try. A less concentrated version of the "solar death ray"
V2H /G is all very well but the cars gzve been around to do it for years. It's the grid that's the issue and the closed energy supply market!! Can't even get an export limit above 7kw in the north! Been contemplating V2H then ditching the grid entirely.
Almost any electric car can provide power through the CCS DC port(for V2G or V2H). Such a possibility is already included in the management protocol. But the manufacturers have not yet announced this possibility, they are probably really worried about the warranty on the battery. Specialists who understand the protocols can easily implement this, of course not officially. You can also use Tesla car batteries and high-voltage inverters to get cheap storage, 60 kWh or more in volume. 100kWh for 10k dollars, an interesting offer)))
The appropriate protocol being in the spec does not mean that the capability is in most electric vehicles. Manufacturers need to install the extra hardware to support the outgoing DC power. This is why only a few models of each manufacturer are listed as supporting V2H/G. And if manufacturers are worried about the warranty, why do both Ford and GM provide the capability in their pickup trucks (in North America).
is there a link for number 1 for the company
Hey Jordan, home come the change in format? Will you be getting back to the old style of videos where you're out doing installs, trouble shooting, repairs? Or do we go watch Cory for that content?
3:44 "And the results were quite outstanding." Really? Did the bi-facial panels magically get sunlight underneath them?
Can beleive how far uk behind
Had enphase plus full glass panels no edge
Bi facial for ages
Done roof tile solar with monier solar roof tiles
All in little old nz
Sadly, our government here (no matter who is in power) seems to view investment in new technology as a headline-grabber instead of something that might actually help people, so they do grants for a while, it's often just a scam dressed up to be appealing, & then they stop supporting it. It's incredibly frustrating.
I doubt that these side or roof tiles will be as effizient as a normal solar panel.
Micro inverters are not really there to be optimizer alone.
Perovskite Panels are still not available biggest thing in the game is Oxford PV, but currently there things are not produced at all even though they say they will start production every year.
Would love to know the pricing for the industrial sized battery storage compared with the likes of a Tesla Power wall (or equivalent) from a price per kwh from a large domestic setup with maybe 3 Power walls?
Or should we just all buy an EV with the biggest battery possible and with a V2G/H option? Maybe buy a 2nd car and leave in the garage and use that as your battery storage?
We really need EVs or BVs, with selfplug-in V2G, V2Home, V2Building.
BVs oversized battery makes the home battery look pathetic. 😊
BVs oversized battery has FREE storage capacity every day, year in and year out.
Vehicles are parked 23hrs every day.
Vehicles drive building to building.
Every building carpark space will have a $60 wall outlet for the selfparking Vehicles Selfplug-in. 😮😊😊😊😊
all very true but I would want my car to have a good amount of charge for when i need it.
I never leave my petrol tank empty. however buying a cheap Nissan Leaf if you have enough drive space for an extra car. leaf just to use it as a home battery could be an economical way to add a large home battery
@steveevans1247 Good comment.
I can easily see rapid chargers on the main roads and at corner stores when needed.
I think that the vehicle computer could be programmed to have enough for the next drive.
The long drive or the daily drive.
This feature would allow savings on electricity supply, gas supply, and petrol supply.
Savings are instantaneous tax-free money in the bank.
Hahaha 👍 Hahaha
Also, the grid could supply to new industries and take your excess rooftop electricity.
So you can remain grid connected as a backup.
In a warming world rooftop, PV panels shade rooftops and help the air-conditioning load.
When the sunshines grid cashflow from customers with rooftop PV crashes.
I don't think that there's much future in using a car battery as a battery for your house - what you're doing there is adding unnecessary cycles to your car, which even with LiFePO4 batteries is a really questionable thing to do to a car battery, given they're not exactly hot swappable (in fact they're normally built into the chassis). A wall battery that you will probably want to swap out anyway after a certain amount of time doesn't have the same issues. Maybe in an emergency, but to build all that tech for an emergency is super questionable - and most cars aren't LiFePO4 either. Vehicle manufacturers don't care because it isn't their battery when you drive the car away, it's an easy thing to shove into warranty terms that it isn't their problem on page 673826. Cars aren't disposable, you're going to destroy its secondary market value because everybody is going to be able to see the data.
Really? Average daily mileage in the UK is less than 30 miles, thats about 6 or 7kWh of energy. Using another 20 kWh of the stored energy would still only be using around 30% of the stored energy. What's more, the average charge/discharge rates for home usage are absolutely trivial - 2kWh of domestic load would be barely 0.03C not stressing the battery at all.
@@faraway5828 all for the low low price of massive depreciation.
With v2h charging solutions, will a solution like sigenergy work with any car? Or will sig energy need to work with the car company to work out the push and pull of electricity. To get the right profiles...
One of the things with car manufacturers solutions was, what happens if i change my car. Will there solution need replacing?
Really interesting and I think in the future Solar will just be a no brainer, but with so much new tech on the horizon I would currently not touch solar with a barge pole as it would likely make sense to change the panels or setup to a more efficient setup before the payback period making current investment not worth it..
The problem with solar walls is there's way less incident sunlight to harvest vs a roof
But more in winter when the sun is lower :)
Are any of the V2G or V2H chargers that are coming out Chademo or will they all be CCS?
There have been a couple of trials of ChaDeMO V2G - it's always supported it but since they lost the format war hasn't really had any more development. Indra did one, but the hardware is almost impossible to get hold of.
@@JamesScholesUK I was meant to be on one of those trials but at last minute fell through but only to charger manufactures indra and wall box made the chargers. Wallbox have said they will only make CCS V2G chargers going forward and Indra won't sell you a V2G chargers currently and since they were acquired by Gulf may never.
I’d heard the VW ID4 has a bidirectional charge capability (well, it has a bidirectional menu in it’s in-car interface)
With 77kwh usable capacity, this would be a good home back-up power option, if indeed V2H capabilities with Sigenergy or Solaredge systems.
Interesting! Thanks for sharing
All the +77kwh ID range offer bi directional charging 👍
The coffee is cold now mate! 😂
So which charger this week? Which battery this week? Was nice to have you there for the first time! Have you been fitting the wrong stuff?
Panels on North in the Netherlands is the weirdest in my opinion. They have tax benefit until 1-1-2027.
I'd love to know if there's a flywheel storage system that would be more suited to commercial buildings
Flybrid systems might have a solution maybe?
As the main problem with EV's is the range I have no idea why you would decrease the range of a car to power your home. The other issue with EV's is that secondhand values are falling through the floor, never mind the warranty on a battery, if I know that a battery has been recycled even more through bi-directional charging then I am hardly likely to think that there is secondhand value in buying such a car.
Range is no problem to most ev drivers, you can sell the electric for 1-2k a year it's a no brainer.
Why would you want to discharge your car battery?
I wish Tesla sold their solar roof tiles direct to consumer, I really wanted them for my shed roof.
walking on solar pannels? EGH, I'm gonna say I hate that.
Why?
All Volkswagen ID range with the bigger batterys 80kw now offer bi-directional charging, I've got a 2-year lease and I would love to claim an extra 2 grand exporting the battery 💵👍
I didn't know battery capacity is measured in kW.
I guess you learn something new (and wrong) every day.
Every day is a school day.
@@deang5622? I don't know tbh I'm only a carpenter but I'm sure most guys will understand what it's meant to be.
Optimizers will not go away, but Microinverters will stop existing. Because everything will go MORE AND MORE DC. So why directly put DC to AC? you have to postpone that.... therefore Optimizers which are DC/DC converters with MPPT will stay even with better shading panels. If you install microinverters it's just a short cut, lazy and will drive your customer up with higher cost to change it later on in the future. (which you probably want right?? ;) )
Is that Vincent Price?😮
Has anyone else noticed that this has become the Jordan show I subscribed to this channel to see the quality installs that all of the guys did, and not just a one person show
Like both formats :)
Well done
I don't see anyone analyzing the impact of having batteries for storing your electricity and solar panels on your home, to our health. There have to be electromagnetic fields, I've only read some people's comments about getting sick from riding in Teslas
Where's all the jobbing videos gone?
Optimisers and diodes don’t do the same thing, surely? Optimisers should behave like an MPPT, optimising the panel output voltage to match the load and panel, whereas the diodes only eliminate the problem of partial shading knocking out a whole string of cells within a panel. Isn’t that the case?
The problem here is that Artisan is clueless with regards to anything to do with solar and battery. Just another TH-cam grifter like the mentioned Matt Ferrel.
@@VinoVeritas_Looks like you are smarter than them😕. You should start your own channel. I ll definitely watch it😅
@@raymondschembri5042 I'm not desperate for TH-cam glory though.
Fascinating video. Just taken delivery of my new Hyundai Kona Electric which apart from being a great upgrade on my previous one - it also comes with the technology to work provide energy to the home. They really have got it together. Well done motability for encouraging us to buy electric cars.

Très intéressant.
Merci !
When? will I get a salesman at my door that can sell it to me?
So the technology that has already been installed is underdeveloped and overpriced. I agree.
Use my 50K Tesla as a home battery!? I think not.

Levels, levels.
I was here to see if you;d got any better, you have got worse, stop describing yourself as an electrician
I don’t think electric cars are the future mate.. you have got to look at the Japanese they are looking at a cleaner fuel . The solar roof tiles look good! Yes definitely got to go towards cleaner energy for sure!
That cleaner fuel really needs to be able to utilise existing distribution infrastructure (Ie a liquid fuel that can be pumped like petrol) or the implementation costs will be too high.
To date, all efforts at synthetic liquid fuels are great in the laboratory. But physically just can’t be scaled up to meet current worldwide demand for petroleum based fuels.
Meaning for the foreseeable future, electricity is it.
Yeah I have have 3 cars soon to be 4 how am I going to charge them mate with out paying loads of money? When they are trying to go all electric in houses we just haven’t got the power captain!
@@justinrowe3346 if you're telling me you need to charge 4 vehicles to 100% every night (say 250kWh a day) of every month, you might have an issue on single-phase but that's unlikely......with 3-phase and load balancing it could be done but, come on, how many miles are the household doing? we run 2 cars now and have for several years and it's unbelievably cheap, we average 1.4p a mile which is a fraction of cost of petrol. If you're serious about this question, get in touch and I'll help you...
@@justinrowe3346 The average vehicle only travels ~40Km a day. With battery ranges of 400km + a 4 car household could rotationally charge each car every 4th day without any issues.
Charging time from a standard power outlet to cover 160km is ~10 hours. Higher amperage outlets can reduce that time down to ~4 hours. Which can be done in the wee small hours while electricity demand is much lower, so plenty of spare capacity to accommodate the charging power.
And of course supercharges can be used as well if necessary.
So there you go Justin, you can have a 4 car EV household no problem.
In so far as the whole grid’s ability to cope, even when every car on the road is an EV total electric demand will only increase by ~15%. And as long as most charging occurs outside of peak consumption periods there is generally plenty of headroom in the grid infrastructure. Though electricity authorities are planning to increase grid capacity over the next 30-40 years to match the increase of EVs.
Sounds like a pain in the ass to me mate and a lot of money bud how much is it to replace a battery on a car ? That’s why people are coming away from electric cars because they are not convenient !
Clickbait, no new sensational tech mentioned.
Never google Bi Facial 😮

Have you ever used Hone panels? I ask because all the new products have the same problem - they're brilliant in the summer but weak in the winter. In other words, exactly the wrong way around for the average consumer's needs. Hone make big claims and post data to 'prove' their value (high outputs in winter) but I'm suspicious when I can find no happy customers here or experts such as yourself who have used them.
Anyone who thinks that highly diffuse and intermittent energy-generating sun boards and wind veins will ever make a real difference to the net zero bullshit is a halfwit. In a first-world country, anything that generates at about one-third of installed capacity and which is used for heating or A/C is useless unless you spend a mega fortune on your renewable array and battery storage. Moreover, bi-directional EV charging is also bullshit. Batteries take more energy to charge than they give out. To suggest that they can be used as backup power for anything more than light general services (LED lighting, TV, computer etc) in your home and then powering your car might be reasonable short term, anything more than that (heating, cooling) is more nonsense.
I wonder if youve lost subscribers in the last few months because this is interesting
Invisible panels, no one cares. Sides of buildings are probably rotten places, always half in shadow, especially in cities to put panels on anyway.
Roof tiles shown look rubbish, perhaps industrial rooves?
Perovskite too small a gain and still not actually here for some time. Maybe in a decade.
Vehicles, we may well not be owning them soon as they will be on demand and driverless. So the use period may turn out short.
