@@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
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..
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
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.
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!
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!
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 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.
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. 🙂
Just to update the facts and figures given in the episode which was filmed over 2 years ago, we can now offer the following. Despite 2 years of price rises for components, the tiles are now £29 each, however cell efficiency has increased to 21.3%, meaning that each tile now generated 17.5 watts. This is in effect a reduction in cost of 17.5% for the same amount of output. As volumes continue to increase, further savings will be passed on.
Hi Chris, any chance you could address some of the issues raised in the comment section. 1. temperature vs efficiency due to loss of airflow under the tiles. 2. longevity, as you mention councils are doing roofs to last 40 years, will the panels last that long both as a solar generator and remain waterproof. 3. maintenance, how easy are faulty tiles to identify and replace. 4. Warranty, had a look at your site and can't see any info on it. BTW I will be replacing my roof in the near future and wanted to do a PV roof like this but the more I looked the more it appeared the drawbacks out weighed the aesthetics. I see samples listed on your website but nothing on the page behind, do you sell to the public?
@@TheWebstaff Hi Dave, Firstly concrete tile behind module acts as a heat sink, second, no glass above module means less heating up thirdly, cells are "cut cell" technology, meaning that wiring is shorter, reducing the effect of heat causing increased resistance, which reduces the performance. As there are no moving parts in solar, there is little to fail, in 20 years of installing I have replaced 1 dead module. With a 25 year cell performance warranty, and using a mineral polymer encapsulation, we expect this length of durability. There is no easy way to notice if one tile fails, as the bypass diodes in the rear of each module ensure that all working tiles in full sun, deliver their full output, with any shaded or failed tiles, reduce the total output by just 12 volts. We supply most of our tiles to self builders and general public.
First question to ask… Does solar make sense in UK. We require most energy in winter…when the sun don’t shine. Better that the investment goes into wind and storage?
People use it to charge cars and heat water in summer months. You’ll get good solar for nine months a year, and you don’t need direct sun. Wind power for homes is probably even more unreliable than solar
…which is exactly my point, you still have to accommodate the other three months. Say, 10 million homes spending £10,000. That’s a huge investment, could it be spent otherwise and solve the year round problem.
Works better on a clear day but can also work on a cloudy day so no it doesn’t need direct light non cloudy day. It can produce without that especially if you optimise the panels
@@JaydenDimaio you are paying for that now. My standing charge is not far a pound a day now, with EDF given a guaranteed kWh price for selling that power, even if we invent something that generates for free in the future.
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.
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
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 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.
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.
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
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?
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
It's called recycling, take a video previously released years ago & re-release it via another channel. It magically appears in someone suggested UA-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".
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.
@@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
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.
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 :-)
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.
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.
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...
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.
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
50% of grid is home load, these installations UNLOADs the grid, and can even give power back into the grid. In a 100% electric world they give the distributed power directly to the users. In 100% electric 5 times more electricity is required. The central concentrated traditional power system will fail economically. The existing grid is decades of construction and resources and $trillions , so 5 times more grid capacity, 40,000klm per million people at $2million per klm. poles , wires, transmission lines, to streets and homes and buildings and ... mind numbingly stupid. Plus 5 times more nuclear power plants at every power station, at $2billion each 300mw system, stupidly big economically and decades and decades and decades and ......... Fossil fuel are energy dense, petroleum, gas, coal. that is all the distributed systems that will be replaced.
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
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.
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.
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.
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.
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.
£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.
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!
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.
3:07 4-6kW systems. That seems awfully small. Can you really get away with using a system that small with ground source heatpumps? My system is 10kW and that only powers the normal electric + my EV. That doesn't include heat or hotwater.
If you want to replace those panels, then you have to replace your roof. Unless you are very rich, this is still not practical (aside from aethetics purposes). We have a 100 watt panel and weighs around 10kg. Each of those tile is 4.5kg and is only 15 watts.
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.
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.
in Australia there are 20million buildings all connected to the national grid. (almost, there is a gap 1,000 miles ) 33kwh from every roof is more than the national total max daily fossil fuelled electric power generation if the generators are lucky and no failures.
Its absolutely barmy solar panels are not installed on ALL new buildings irrelevant of use and subsidised for older buildings. Goes to show how little they actually care about climate change. Germany is the only country I have visited and they have solar panels everywhere on all buildings. Oddly places like Spain and Portugal have very little.
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.
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.
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.
its a shame that here in the UK the current government decimated the solar schemes 'getting rid of that green crap (David Cameron)' if we had help thousands do solar, insulation we wouldn't be in such a bad position now. The investment in this type of solar would be much further advanced and have had a high uptake and at higher volume comes lower prices.
Nice, give me big glass panel solar at a lower price. 2022 solar still expensive up front, many install scammers & bad deals including solar leases, or lease by another name if you have to move they put a lien on your house.
more expensive to buy ,more expensive to instal, less efficient panell. horrible to service (how long you will find faulty tile compare to panell) and for me the pannels looks much beter..and the load is the same or somebody believe that the extra solar tile on each concrete tile dont ad? and structualy you make big hole in each tile make them much more easy to brake.
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 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.
The smugness and ignorance of this guy is unbelievable. These panels are not very efficient; not all houses are orientated to be able to use solar; the cost of these is far higher than conventional panels and there is a very good reason why homes are limited to 16 Amps input to grid. But then again, you would not expect an elitist who gets most of his electric toys for free to understand real life or electricity..
Obvioudy this a great as it gives an option ideal for new builds. As a society we need to stop messing about, in the specific case of new builds it shoild ne necessary to get planning exceptions approved if you are not going to install solar, no real excuses

As there are no moving parts in solar, there is little to fail, in 20 years of installing I have replaced 1 dead module. With a 25 year cell performance warranty, and using a mineral polymer encapsulation, we expect this length of durability.
There is no easy way to notice if one tile fails, as the bypass diodes in the rear of each module ensure that all working tiles in full sun, deliver their full output, with any shaded or failed tiles, reduce the total output by just 12 volts.
We supply most of our tiles to self builders and general public.
First question to ask…
Does solar make sense in UK. We require most energy in winter…when the sun don’t shine.
Better that the investment goes into wind and storage?
People use it to charge cars and heat water in summer months. You’ll get good solar for nine months a year, and you don’t need direct sun. Wind power for homes is probably even more unreliable than solar
…which is exactly my point, you still have to accommodate the other three months.
Say, 10 million homes spending £10,000. That’s a huge investment, could it be spent otherwise and solve the year round problem.
@@markthomasson5077 nuclear.
Works better on a clear day but can also work on a cloudy day so no it doesn’t need direct light non cloudy day. It can produce without that especially if you optimise the panels
@@JaydenDimaio you are paying for that now. My standing charge is not far a pound a day now, with EDF given a guaranteed kWh price for selling that power, even if we invent something that generates for free in the future.
Iv'e been saying forever that every new building should have solar on it
The definitely will be solar on every roof, is the only way they be able to double the cost of electricity and!
Tesla: that's just a shit copy
No sign of any ppe , disgraceful
As soon as he mentioned the cost per tile, you lost me ! £1 to £30 per tile ! I think we need to let the Chinese loose on this idea !
So you’re recycling your old videos now?
Absolutely ridiculous mark-up. Too greedy. Shameful.
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.
and if my maths is right it would take around 12 years to pay off 🤷♂
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.
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
Having all solar on south facing roofs would be a mistake as you would achieve too much peak generation.
@@timrothwell33 energy storage and especially electric cars would serve to increase overall demand and lower individual supply.
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 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.
A no brainer if you've got more money than brains! I'll keep my panels thanks.
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.
We desperately need more of this.
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
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?
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
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 UA-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".
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.
Hmm. £300 per 150w? Far too expensive.
If the rows are connected in series what happens of you get a fault on one tile
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 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.
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 :-)
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.
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
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 ?
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.
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.
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
50% of grid is home load, these installations UNLOADs the grid, and can even give power back into the grid.
In a 100% electric world they give the distributed power directly to the users.
In 100% electric 5 times more electricity is required.
The central concentrated traditional power system will fail economically.
The existing grid is decades of construction and resources and $trillions , so 5 times more grid capacity, 40,000klm per million people at $2million per klm. poles , wires, transmission lines, to streets and homes and buildings and ...
mind numbingly stupid.
Plus 5 times more nuclear power plants at every power station, at $2billion each 300mw system, stupidly big economically and decades and decades and decades and .........
Fossil fuel are energy dense, petroleum, gas, coal. that is all the distributed systems that will be replaced.
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
The best idea I've seen yet UK government should change the planning law and make this sort of thing compulsory.
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 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.
Isn't this a re-issue of this video! I seem to remember watching it on Fully Charged over a year ago?
So stupid !
I do prefer standard pv, way easier, chipper and extra roof thermal insolation.
It's a shame they didn't take into account the shadow at 1:54 ..
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.
Fill the roofs before using up farmland for solar.
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.
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
He hit the nail on the head when he said It's A No Brainer.
Great new word: Solarize.
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 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.
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.
That's way too expensive. Definitely a luxury product rather than something for the general public. Shame.
£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.
Genius,somebody tell Lizz truss!😁if she can understand it!naughty !😉😁👍😎
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!
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.
3:07 4-6kW systems. That seems awfully small. Can you really get away with using a system that small with ground source heatpumps? My system is 10kW and that only powers the normal electric + my EV. That doesn't include heat or hotwater.
If you want to replace those panels, then you have to replace your roof. Unless you are very rich, this is still not practical (aside from aethetics purposes). We have a 100 watt panel and weighs around 10kg. Each of those tile is 4.5kg and is only 15 watts.
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.
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.
Building codes in appropriate sunny areas should make solar mandatory.
in Australia there are 20million buildings all connected to the national grid. (almost, there is a gap 1,000 miles )
33kwh from every roof is more than the national total max daily fossil fuelled electric power generation if the generators are lucky and no failures.
Its absolutely barmy solar panels are not installed on ALL new buildings irrelevant of use and subsidised for older buildings. Goes to show how little they actually care about climate change. Germany is the only country I have visited and they have solar panels everywhere on all buildings. Oddly places like Spain and Portugal have very little.
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.
That's a lot of collective resistance from all those plugs.
Maintenance on faulty panels would be a nightmare. No thanks.
For about 5 years now I have been saying the same thing, ALL new roofs should be solar...period.
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.
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.
its a shame that here in the UK the current government decimated the solar schemes 'getting rid of that green crap (David Cameron)' if we had help thousands do solar, insulation we wouldn't be in such a bad position now. The investment in this type of solar would be much further advanced and have had a high uptake and at higher volume comes lower prices.
I like this. There are so many good ideas how to go green its just great!
This is great if you're building a new home, however, I don't expect to re-roof my house in my lifetime.
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!
4kw systems are small. 16 x 250W, Now 16 x 410W = 6.6kw, over 33m2
We have a GSE in roof system which is cheaper and solves the same problems. So I can't see this taking off really.
Nice, give me big glass panel solar at a lower price. 2022 solar still expensive up front, many install scammers & bad deals including solar leases, or lease by another name if you have to move they put a lien on your house.
Thats great, I like it.
How much it will cost a roof of a house around 100m2 surface floor
more expensive to buy ,more expensive to instal, less efficient panell. horrible to service (how long you will find faulty tile compare to panell) and for me the pannels looks much beter..and the load is the same or somebody believe that the extra solar tile on each concrete tile dont ad? and structualy you make big hole in each tile make them much more easy to brake.
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 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.
The smugness and ignorance of this guy is unbelievable. These panels are not very efficient; not all houses are orientated to be able to use solar; the cost of these is far higher than conventional panels and there is a very good reason why homes are limited to 16 Amps input to grid. But then again, you would not expect an elitist who gets most of his electric toys for free to understand real life or electricity..
I just don’t like th look of solar “It’s ugly………..solar is smarter than ugly
Why not make roofs that are a rectangle and use ordinary panels that are weatherproof (see CAT centre)...? No need for any tiles and no concrete...
I’ve been waiting years for someone to do this!!! 💪🏻👍🏻
Obvioudy this a great as it gives an option ideal for new builds. As a society we need to stop messing about, in the specific case of new builds it shoild ne necessary to get planning exceptions approved if you are not going to install solar, no real excuses
Energy companies should offering people new roofs as long as they get the electricity.
Ok everybody keep putting that piece of video with the guy standing on the panels,it annoys me
This is a good option for conservation areas where conventional solar panels would be hard to get through planning.
It should be government legislation that all newly built houses incorporate a solar power roof
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
What about when there are issues, would be paying the roof up to diagnose and fix an issue...
All house builders should have to use this kind of tech. Imagine if every house had these on.
If every house had a solar roof and battery storage, we’d barely need the grid, or nasty dictators!!
