Based on this episode of GD, my wife and I have already contacted the company in Estonia to get a solar roof for the house we’re planning to build. Who doesn’t want free energy to warm the house, heat the water and charge the car rather than being charged and taxed for thousands a year?
Do you have a link?
What’s the company called? Cheers
My dream is to be off the grid because of taxes
And free money to build it. Oh no, you need to pay, and a premium, for a premium solution, that work worse than general solar. Nice.
@@MacLimitRange A solar roof, i.e. a roof made of solar panel roof-tiles, is cheaper than the standard roof and then solar panels on top of it.
Quote,
for a premium solution, that work worse than general solar. Nice.
Nice
It’s a shame that the government isn’t making these solar roofs mandatory on all new build’s and renovations.
Explain why its a shame? What would you do with 20x the grids power requirement trying to be put into the grid? Additionally this drives other power generators out of economic viability so there is no one providing electricity when the sun isnt shining enough (which in the UK is far longer than it does shine for).
@@yt.damianIndustry also requires power, not only domestic. Any excess can be stored, by various methods. Yes, let's put the oil, gas and coal industries out of profitability.
You are correct. Industry requires power. Reliable power. Power when it needs it. Solar does not power industry. Where can this excess power be stored? Yes lets put the oil, gas and coal industries out of business - lets destroy the very things our civilisation is built on, lets destroy the very thing that makes everything else in our lives possible. So much stupidity being taught today. SMH. @@tednruth453
Mandatory on renovations? That’d be costly lol...
yeah because everyone in you fantasy can afford top install these. Pull your head out of your ass and look at the world around you.
Simply wonderful, we need more people like this in the world 😊
Given how sleek it looks, it might be worth it. But i think, mainly for ppl who haven't looked into it, it is important to consider the cost. i am in sydney Australia. My traditional (not sleek) 10kw solar system generates 80kwh on a sunny day(19th Nov 2023) and the initial cost is no doubt much lower. I broke even in about 2-3 years. Of course, different location, different house, different size of panels, can't just compare directly. But if you really want to 1, go green 2, go sustainable green, you might realize there is a long way for this product to go and you might be greener with a traditional solar system. Again, this roof is beautiful, it is worth someone wants the visual to go for it, I agree with that.
They really committed to doing what they wanted to do, not what they should do. They are generating so much power that they can't actually sell it back as the local grid doesn't have capacity.
They should have just used fewer normal panels.
The company is called Roofit Solar.
What an amazing build, I would like to see these solar roof pannels fitted to every large warehouse in the UK. I've love to have a roof like this on my 3 bed but fear the cost will be prohibitive at the moment
This bloke stole my dream! 😍
I agree the 19th Nov was a good day - I got 39kW out of only 5kW system - my best day was the 4th Feb 2023 where I got 40.5kW. I've subsequently updated to 10kW and so far I've got 81.7kW on 5th Dec 2023 - the newer panels are giving more than the older ones even though they're kinda facing the wrong way.
This kind of thing makes me so happy!
Simply astonishing
this!!!! I have wanted something like this!! now I just want to get in touch and be like! LET'S MAKE MORE!!
Fantastic !
Good luck on a sunny day and in the u.k like you said hopefully it works.
Super!
Woah holy shit that's awesome I hope this will be available or improved more when it's available for export orders, and ❤the house are damn looking sick and simple at the same time

Good on them. 4x overbuild of solar + 50 hour backup battery backup and the grid is decarbonised with electricity so cheap we could repatriate so many industries.
When I was getting panels put on my roof I was told there was a maximum amount that could be installed before the government starts looking into slapping taxes on. Part of the problem with projects like this and smaller scale ones are that the power companies can charge whatever they want and change it on a whim while the home owners producing the power for them don't see any benefit.
That said there's a lot of redundant roof space and tall buildings that could be fitted with panels rather than cheap cladding if only we had MPs willing to have forward thinking beyond cushy seats on a corporate board. Neither of the big two in westminster have any plan or intent to do anything but can kick and hope they don't have to deal with the problem when its unavoidable.
Amazing, I see a comment below saying about the government, not making it mandatory. Why would they there’s no money in it for them
Splendid accomplishment - we can but hope that in time the costs will come down so ordinary folk can afford to do something similar.
That's where the real gains from 'renewables' can be found - reducing the demand from the grid. Present thinking is too focussed on replacing the generation sites with renewable sources and it just will not fly, not with the foreseeable technology. Homes becoming self-sufficient for energy would drop the energy budget by a third. By the way, the fact that domestic energy use is *only* a third of the total is a fact that should be more widely known.
Homes will never become self sufficient as self sufficiency isn’t a real achievable thing.
All new builds should come with renewable energy generating sources, solar roofs etc. better insulation.
Hope they have easy access to clean out those gutters in the valley’s of the roof.
£120,000 install costs, I think the energy companies offer 15 pence per KW feed in tariff, it’s going to take a long time to recover costs. Not sure if battery storage included in costs. My electricity bill is £60/mth.
This is really cool because one of the drawbacks of solar is just how ugly solar panels look. This looks so elegant in comparison.
Agreed. Almost looks like the lead sheets of the old days.
But what about damage ? will it cost much to repair / fix / replace ?
@@geoffreystuartboxx you mean... hideous? I mean... I don't know about the rest of you lot but I do not give a monkey's how my roof tiles look if they can provide that much energy. Now, if there's a choice at the same cost, both produce good energy, and one looks like normal roof tile I might choose that. But I wouldn't ditch the properties of the solar just to satisfy some cuteness factor in case I felt the need to find somewhere to stand to admire my roof for a few hours every day.
How ugly solar panels look is a deeply damning indictment of our lives really, when you think about it. It's like people saying they chose not to get an EV because none of them looked sexy enough. Just ignore that they're better in every way than ICE.
I bought the beautiful kettle, not the one that boils water cheaper, quieter, and faster. *bangs head on desk*
@@jonevansauthor Couldn't agree more!
each to their own, I like the look of solar panels, to me it speaks of future, energy security and clean energy, I also like to see wind farms too, some people say they look horrible on the landscape but I enjoy them
Wow 230KW/day ...100% impressive 🩶🙌🏽

Anyone know the name of the company in Estonia?
These might just my project too.
Roof panels make, name & company provider please. I'd love to cover my extension with that.
roofit solar
What happens if you need to change a broken panel or 2?
You simply replace it :)
How about that on my cathedral roof design on my Australian house… as long as it does not blow off in 120kph winds…
What is the surface area of the roof?
Estonian solar panels? Solar panels from a country without the solar input to make the use of solar electricity viable! Why can't British companies get on with doing something innovative and useful for a change? Just like the high precision build-in-a-factory wood pre-fabs that you can only get from Germany. We need homes with sustainability, fast build times and so on and we have to constantly go abroad to get the solutions, utterly lamentable.
Exactly my sentiment. Sometimes I just despair of the UK.
A big part of the issue is that in the UK & Ireland there’s a tradition of building cheaply.
You can’t do that & innovate.
Greed and laziness.
"Solar panels from a country without the solar input" It may not be as severe, but Estonia gets more sun on average than the UK so it more than enough balances it out.
Why don't you try?
where is the full episode???
But why polystyrene when there are mycelium based alternatives?
Where is the whole episode?

Great name for a band😂
Does anybody have the Estonian Company name and location?? thanks
How on earth did the DNO get approved? I cant even get 8kw approved from SSEN. Also do the tiles have optimisers?
Would love to know this, but I imagine the answer is money.
@@joshperkins2683 brown paper bag to someone.
It was covered in the show and as it turns out, there's a cap that the DNO placed and it was considerably lower than he was generating (something like 30 kWh if I remember rightly). Which means that the other 200 kWh he's generating just vanishes into the air (so to speak).
He hasn't. It could do it all, but can't because of the DNO. It was clearly something they didn't factor in when designing the system.
IMO, since they seem to have the money, they should just supplement it with some home batteries.
@@Unshou I believe it's called "clipping"
so if 1 house uses x amount of energy and they produce 4x, that means the village they live in consists of 8 houses
or there giant house uses a lot more electricity than a normal one???
Or the half the village is during peak electricity generating periods, while the house still has to use energy when it’s dark
What is the name of the solar company or the technology called?
Roofit solar
Can the owner of the property share some data on how much this 400-panel solar roof has generated over the last 1 year? It would help other home-builders understand the return on investment from the £118,000 cost of the roof. With some assumptions, my rough calculation is that over 12 months in the south of England, the roof would generate 80,000 kWh. Current average electricity price per kWh is £0.30 so that's a saving of £24,000 per year, if the homeowner would otherwise have purchased that electricity. That would be a fantastic return on investment. However, even if the homeowner ran 2 electric cars, they will probably use only 25% of the electricity. The other 75% would be exported to the grid, for which the homeowner would be paid about £0.08 per kWh. In this case, the return would be a saving of £6,000 on electricity they would otherwise have purchased, plus £4,800 for the exported electricity. Total of £10,800 per year, which is would be a return of 9%. That's still a very good return - much better than savings rates and even as good as long term returns from the stock market. Plus, the homeowner probably saved £15,000 on the cost of laying traditional roof tiles. But more important than all of that - this homeowner has made an outstanding contribution towards tackling climate change. He has built an inspiring project and a sustainable legacy for the future.
Given the green push by government, why aren't all new build housing being forced to install solar roofing,
My god, those look stunning. I'd love to replace my ugly solar panels on my roof with those
Huge amount of concrete though....
If it doesn’t work out they can paint it orange and sell it to B&Q
Imagine if it was used as cladding also .
Exactly, I don't get why this is always associated with roofs.
@@aliasgharkhoyee9501 I think it's because the efficiency goes right down if the sun's rays are at a steep angle to the surface rather that full on. That said, it would provide a bit more energy.
Yes, but the economics of it would be terrible. You'd be paying £100k and get £30 of energy per year. @@fburton8
Many years ago a dairy farmer paid a million dollars for a metane collection and generator i bet now for less one quarter of that and your payback would be much shorter
The $64.00 question is how much he receives for feeding into the grid.
It was covered in the show and as it turns out, there's a cap that the national grid places on exports and it was considerably lower than he was generating (something like 30 kWh if I remember rightly). Which means that the other 200 kWh he's generating just vanishes into the air (so to speak).
So basically, he's waiting for the national grid to catch up to the technology.
@@Unshou I think you are not including what they use at that property.
@@QRCCD1999 Good point. That said, I know it's a huge property, but I'd be impressed if they used more than 50 kWh per day.
Unless this video is a few years old then its technically not the UK's first passifhaus, I had the pleasure of working on the UK's first passifhaus and it was actually a primary school in Edinburgh, I say it was a pleasure it was an absolute nightmare. Everything had to be to a certain specification and a gap of 3 millimetres in-between the insulation could make it fail the test so you would have to fill it with expanding foam
They said it was the meant to be the first passive house 'premium'.
@@aliasgharkhoyee9501 I can honestly only imagine how crazy that must have drove the poor guy because to get it certified the will come out and if that house isn't able to act as a vacuum seal it won't pass the certification
I would like to know the name of this company for future reference
roofit solar
@@TheAdamRBell Thank you
Zero information or specs about the panels used. Is this real?
good point!
Polystyrene?! WHY?
Great initiative. However!! "An average household use 8kWh per day"??? I guess gas is making up for cooking, waterboiler, heating ... Average house without other energy sources use 5-10 times that. On a good day my ugly solar panels gives me 120-130kWh per day and they cost me less than £20,000.
Edit to my previous comment yes this video is a few years old my bad 😂
Did he say 230kW???
Lol in December 2023 they broke down ,,they didn't work over 65oc in summer time,and heat pumps don't work near freezing temperatures
Might want to tell that to Sweden and Norway because their heat pumps work in sub zero temperatures.
Great,, why don't we all build one,,,, cos we're realists
Jamie Carrahger's dad 😂
Why did they not face all the panels south?
The whole idea was to integrate them into the roof. That would have been a massive array on the ground
@@hughmarcus1 change the orientation of the roof?
@@smashingturnips5353 simplistic answer. You need to understand the concept of passiv housing
If this is so good as a roof and solar.there must be draw backs or we would all be using it , cost , maintaining, damage , and the final one how long does it last , before replacing it . They never tell you this on these shows.they just tell you the positives never the negatives . Please in future tellus the truth . Warts and all
Are they literally supplying half the village or do they mean it's the equivalent of supplying half the village
Equivalent of supplying half the village. Turns out he can only export a small fraction of what he's generating due to DNO and/or technical limitations with the grid
@@Unshou I wonder why he bothers, given how low the feed in tariffs are
I can't see these working.
If he was worried about needing just another 2% of solar, then he should have added a patio with solar on the ground, or a solar driveway. You can get solar panels that are made to be walked on or made for people to drive cars on. That would give you the extra he was looking for.
Also in the winter if you have snow you are more likely to clear the snow off the driveway and patio than the roof.
You can bypass underneath like any other panel or replace it. 95% of the panels could break and they would still have more than the average house needs 😂
Getting slightly irritated by the lack of completed builds on this series
Nice to generate solar power but a shame about the building materials. Polystyrene, steel, concrete. Are there no environmentally friendly options such as hemp available?
That's what Passivehaus is about. Same with EVs. You only care about the total emissions over lifetime, which is lower for both things. Nothing about Passivehaus standards or philosophy, discourages using better insulation or whatever, when it becomes available. If hemp insulation were better, they'd use it. Remember that wood, hemp, polystyrene etc sequester the carbon in them. Heating over the lifetime of the building is obviously extremely important. In this case, which is sort of overkill, the extra solar he's paid for will possibly earn them some money if the power company pay them for the energy, but will definitely dramatically reduce this house's environmental impact/offset it. It's not good growing your building materials, rather than mining them, if that produces more pollution over the lifetime of the building.
The moment a significantly better form of insulation is available and cost effective, it'll take over. I'm sure the hemp people are working, slowly because they're stoners, on making their product more useful too. Doesn't matter what they'd like it to be though, it only matters what the science says and the science does not care if your product is a super special weed you grew, it only cares about the data.
@jonevansauthor I hear ya but when you say “cost-effective” are you taking into account the amount of subsidies going into fossil fuels and the like, vs their true environmental cost? We need to subsidise the right things to make them economically viable if they are absorbing carbon. 🙏🌍🌱
@@jonevansauthor Mm. Only I wasn't speaking of insulation, but things like hempcrete. And industrial hemp is not grown and processed "by stoners" because you can't get high from it.
This is kind of missing the point. The house is designed to have a net positive climate impact. That includes the materials.
@@rinnin I'm saying people use the most cost effective insulation and/or the most effective one. None of it is made of arsenic or polonium. The eco-friendly bit comes from the lifetime of the product, not whether or not it's grown on the back of a sheep. And no, it's not economically viable to have to subsidise building materials. That, by definition, means they're not economically viable.
I'm for Passivehaus because it's clearly better than 'old fashioned draughty house with poor insulation' or 'normal American house' or whatever.
I am not worried that the Passivehaus folks are conspiring against us by employing the most polluting building materials they can find because that's completely contrary to common sense and the whole point of the thing. The people who want to do that, work for the terrible national home builders who churn out awful properties. Or Apple.
Lovely build , but why on earth do you need it so big, absolutely ridiculous.
The question is how long do they last? If it is 10 years you need to work out how much it will be to replace the entire roof against the savings then get several skips to dump the old panels 🤷♀️
The most uneco friendly passive house ever built. Huge amount of energy, fuel, machinery, raw materials, steel production, wood transportation, imported components and all burnt to produce this monster. Meanwhile they could have used local stone, local stonemasons and built a small, less materialistic, cosy abode. The level of human stupidity knows no bounds. We have lost all sense of proportion and what is really important. A statement house sized to meet the owners egos.
Erm elon musk has solar tiles 😂
The elephant in the room is definitely the size of the building. In no way eco that’s for sure!
It's unbelievable that all new buildings don't have solar systems as a mandatory requirement during construction. Reducing the grid usage of existing homes and businesses is great but what is the point when we are clearly building new problems every day.
Very impressive. It would of consumed a lot of recourses in its construction.
So does a house without solar.
The loss of interest alone on the £118,000 invested is £5,000 a year. EVEN IF that roof is generating 230 kW, that's £62 'saved' in electricity consumption (@27p/kWh). At that rate (and of course it wouldn't be, as I feel sure he chose a nice sunny day!) it would take seven years to pay the investment back*. In reality, I doubt he would ever see a return on his investment. I'm afraid that in such examples, maths is rarely used honestly. And this is even before you factor in generation degradation (which is 0.6% on ordinary panels), maintenance, and replacement of inverters and batteries (assuming he has them) - which are an incredible cost every 12-15 years. Indeed, such typical systems never pay back their investments.
*I would have to see all the data to carry out a real cost analysis. Money saved can be invested to pay for inevitable future costs, and there's inflation and energy price rises to take into such an account of the data, but a simple calculation can still be made to show the futility of such schemes.
You don't do the maths as as a return on investment. You do it as a "What other investments could give me this return." So cash sitting in a bank account might give you a couple of %, but cash invested in a roof will save you more than you could earn elsewhere. It's contrariwise, but it makes sense.
@@tomwinchester3582
Tom, the vast majority of people who put solar panels on their roof, do it to save energy, and thus save money. I know because I have been doing this for some years now (talking to installers), and I am myself in this field. 100% of them talk about their 'payback period'. This is called ROI - return on investment. However, in typical situations, there is no ROI - none at all. Indeed, it is a lesson in how to lose money. Virtually 100% of the people I talk to are not aware of this.
So, what if you had kept your invested capital on a typical £10k system - at 5% for 30 years? Your investment would have grown to £21,000 even accounting for inflation at 2.5% per annum. It would be worth, in real terms, double what it’s worth today. Remember, inflation hits BOTH investments at the same rate. Also, you could get better than 5% interest by investing it into a pension for 25 years. You receive tax relief at your highest marginal rate for personal pensions contributions; however, access is restricted until you’re 55. Once funds are in a pension, they grow tax-free, and it’s a really efficient vehicle for long-term savings...as is property. A pension would likely grow 2.5% ON TOP of the inflation rate, and even if you assumed a medium pension growth rate, the value of a £10,000 pension investment would still be £25,000 in 25 years from now (Aviva). Alternatively, you could invest in Ripple (wind turbine) account and see a 7% annual return on your money.
So, I'm afraid you are doubly wrong. A TYPICAL solar panel array is a LOSS, and an alternative investment is a gain. You cannot fool mathematics.
@@tomwinchester3582 So don't rely on a bank account to give you a return. Surely its about cost per kwh? ove time.
Cool solar product. I dont know where he got 8kwh per day from though for the typical daily electricity for one house. Its more like 30kwh per day for an average house.
in the six years since we retired, we have consumed a daily average of 8.17 KWh of electricity and 2.14 cubic metre (23.8 KWh) of gas in our 1980s four bedroomed detached house. So yes 8 KWh of electricity, but over 30 KWh of energy. A heat pump could replace the gas and reduce the requirement by around 20 KWh, and insulation and double glazing might save a further 2 or 3 KWh.
9kwh here in my 4 bed house in the U.K.
Agreed with both of you. Not 30kwh per day.
You're correct, it's nonsense. Maybe he's thinking of homes having gas as their heating. We're all electric - our annual averaged daily consumption is 38 kWh, and we live in a 3-bed detached bungalow.
This was a ridiculously over sized vanity project.
So !
Hence the title, Grand Designs...
It's always hilarious when they call builds like this sustainable when the house is about 5 times as big as it needs to be and made of steel glass and concrete
@@DarkJonas33 Yeah, could house a small village.
I'd argue though, if he is powering the other houses, assuming for the long term, that must be more beneficial than not? People will have big houses regardless.
Why the stupid shapes, more expense and no benefit.
Typical house uses 8kwh a day? Lol that's a straight up lie.
Right. I'd say we're fairly energy conscious in our house and we use between 15-20 kWh per day.
That’s probably because your house isn’t super insulated and air tight.
@@longjonwhite Regardless of how insulated or air tight my house is, I still need to run the washing machine and oven and iron and charge the car and have the lights on every day.
We're talking electricity generation here, not heating (although admittedly some people heat their house with electricity if they have a heat pump).
