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

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.

@EleanorPeterson Жыл бұрын
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.

I've got roof integrated PV panels. They are ordinary PV panels with a special mounting adapter made by a company called GSE. It's smarter looking than an "on-roof" system, and it dramatically reduces static load on the roof. It's been in operation for 2 years and has withstood Storm Arwen, Malik and Corrie without damage, and it's shed some of the worst torrential summer downpours I've seen without leakage. This looks good, but the labour costs are much higher for installation and because of the number of individual elements and connections, the warranty callouts are likely to be higher than they would be for ordinary panels. There's also a complete lack of choice in this form factor, so warranty issues in the years to come are likely to be met with obsolescence issues, whereas standard sized panels will probably have plenty of replacement options to choose from. Since the pandemic, I've been tracking the PV/Concrete tile price ratio. Prepandemic, it was £10/sq metre for concrete tiles, vs £50/sq metre for solar PV. So price ratio was about 5. Now it's £20/sq metre for concrete tiles, but £100/sq metre for solar PV. Price ratio is the same. So personally, I think trending solar PV tech will focus on reducing rooftop costs. That means lighter rooftops which also benefit from lower transport and manual handling costs. I also think simpler fixing systems for both panel and wiring will continue to reduce labour costs. This technology of fixing PV direct to an old fashioned concrete tile doesn't address these cost objectives.

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.

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?

The idea of everyone using these tiles is a great idea however you can't just go on Ebay and buy them, I suspect you can only get them if you are a construction company, so though this is a good idea most people won't be able to get their hand son them. Like so many things DIY will have to wait until the tech trickles down to them. But that's probably why you don't see these things being used everywhere, you just can't get them.

This 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.

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 drilled hole right in the middle of the roof tile concerns me a little. Over time, moisture can make it's way under the solar panel through the hole and under the roof. Same if the solar panel breaks. This area get's weakened alot. It would be more safe to put the electric connectors on the top area of the tile where they overlap.
@scottkolaya2110 Жыл бұрын
The roof is an open air design. Under the panels (below the nailing strips) is water barrier membrane. Cement tile roofs like these aren't sealed. The tiles just lay on top of each other. If you are concerned about the water making it's way under the solar cell, you should be more concerned about the gaps between tiles since the tile above doesn't overlap the seam below by more than just the small overlap area where it's nailed 1:35. The tiles only have a small channel on the side under the adjacent tile for water to drip down. You can see it on the left side of the panel @ 1:24. But nothing is sealed, wind can blow water right under. edit: although under closer inspection at 0:45, it seems like they only have a vapor barrier under the nailing strips and not sure what's creating all the gaps underneath the strips. The waterproof membrane seems to be on the lower part of the roof, but the vapor barrier goes under it instead of over. This seems like a recipe for rot. It would be at least where I live. Maybe it works for the climate there. Edit 2: at 4:26 they seem to be just pushing down the vapor barrier to fish the wire under the strips, so that seems like there's nothing below but rafters. Maybe the entire attic is open with just the vapor barrier to catch the small drips that make it past the tiles with no decking at all.

@@scottkolaya2110 I'm familiar with this type of roof and I'm not concerned of a well proofed roof design. The water barrier normally stays dry and acts like a second security layer when the roof tiles leak because of damage or misalignment.The big difference between the overlapping gaps of this and any other roof of this type is that they are vertical in the way water runs. The solar panels are not full-area glued and most important their gaps run horizontal. This way the water can easily flow under right to the drilled hole which damages the waterproof system of this roof design.

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 :(

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.

I bought my brand new house in 2020, we bought the house off-plan and the builder had no option for solar to be installed while they built the house. I could not believe it, I wanted to have solar installed and I was told I could not because they do not provide it as an option. They grudgingly put in a car charger which I believe is actually not up to the task and will need to be removed and replaced with the correct wiring! The housing industry is broken.
