Solar Roof Tiles - should every building generate its own power? | 100% Independent, 100% Electric

[@AdrianNelson1507]

@Scratchy Ballzack a fair point, I can't speak to American prices but in the UK all new build prices contain a very decent margin for the builder. Housing is ridiculously overpriced here too, my argument is that the free market has had plenty of time to do the right thing though.

This roof that Robert has come to see is made up from 900 solar tiles! These tiles deliver all the benefits of solar, but without the aesthetic compromise of huge panels added onto your roof that require systems and structures to manage the weight and connections.

Let me understand the proposition here. You are going to let these guys take a solid concrete tile and put a sizable hole in the middle of it and seal it with some glue and attach a plastic panel to it to sit out in the sun for decades? The panel has 1/3 the longevity of a solid tile (not sure the longevity of as tile with a hole in it). When the panel fails, you check all your panels and connections. You finally find the one that failed and you want to replace it... Just think it through. Maybe having panels attached on the outside is not that ugly after all?

@@BEATmyguest31 This is why a double-layer roof is actually a good thing. You have the lower portion of the roof fully sealed, insulated and drained. Between the two layers is a drainage plain and keeps the top deck cooler, extending the life of the roof itself.

[@povelvieregg165]

Whether this system, Tesla solar roof or something else ought to be made more of a standard. I did back of the envelope calculation which says about 52m² on every household would give enough power for the whole country. And I am talking giving power to factories and such. The 52m² would cover more than the energy needs of the household itself. Households only consume about 30% of the power in a western country. Obviously there are complicating factors here in that the power will not be delivered exactly when you need it. But it does give a sense of just how much potential there is in covering every roof. And 52m² is a pretty modest area. I would think a normal house roof is at least 80-100m². But imagine having a house with 100m² solar panels. It will produce 75.00 kWh on average per day. That can charge up a typical Tesla car battery. However your average western household only needs about 10 kWh per day. So you actually got lots of power you can sell to the grid and make money. With the big Tesla car battery you can store this power and just sell it when there is demand to make a pretty penny. And the neat thing about solar is that you can in principle expand as you got money. You don't need to build 100m², you could build smaller. Then make money off that for some years and later expand. With the Tesla million miles battery and bidirectional charging we are going to see some crazy no opportunities for people to have energy independence and actually make money from their home house selling power.

[@abelincoln78]

These look really nice, though it sounds like they’re using a single inverter per elevation which I think would suffer under patchy cloud cover vs a panelized system with an inverter for each panel. It really is infuriating isn’t it when you see a field full of solar panels and a bunch of warehouses next door with none. Or if there’s a huge parking lot the same size right next to it. Or a giant housing development with no panels installed! It really is shameful I think to not fit panels to the many convenient spaces left in our built world and steal nature instead.

[@JPRTonundFilmstudio]

What is with the heating up of the panels in direct sunlight? As I recall solar panels loose efficiency when their temperature rises and the traditional way of building a solar roof enables the panels to have cooling by fresh air being able to circulate underneath the panels, isn't it? So these roof tiles would have a worse efficiency?

[@Rubblechops]

Good question. Anyone know?

[@200501012]

As a guess I'd day having them on a cement tile would help dissipate the gest into the tile somewhat. But that's just a guess. The roof is still black after all and cement can hold heat for a while so not really sure still. Good point though.

[@abelincoln78]

I don’t suspect peak temperatures are much higher, largely since I also suspect air cooling benefit under a normal panel is negligible. Now. . . add water cooling and harvest the waste heat to pre-heat hot water and reduce heating load in the winter and you’ll have an extra high performance roof!

[@jamesmcmillan2656]

I was thinking the same thing, maybe only good for cooler climates

[@melange78]

It is part of the reason why I am skeptic of this. The other is that it is likely much more serial panels connected in each array which can cause problems for the charge controller. Most likely you will end up with a more expensive multiple charge controller solution if you go with this system than just adding larger panels.

@@rogerbarton497 Good luck with that. The only way to access the wires is by removing panels. Basically you'd end up removing a big chunk of the roof to find a fault.

I was wondering this as well. I wonder if you could access the cabling from behind. I also wondered if these are interchangeable with normal roofing tiles in the event a panel failed (in a way it was letting water in) and the company was no longer around.

[@BrianJense]

@@rogerbarton497 Many panels come with micro inverters now a days. These will often be able to detect if a panel is producing output, and if not, disconnect the panel from the series. This way you never lose a full series of panels.

Brian Jensen exactly how SolarEdge works and it also tells you which panel is at fault so less need to guess

[@SkaterJanF]

What we currently see fires occuring in PV installions, built in roofs. The failures are generally caused by faulty connectors of the PV installation in combination with the built-in feature. When we look at this concept we see a lot of connections which can fail. The failure mode of the DC currents is that you get arcing and heating up of the connection, resulting in fires.

Unfortunately in the "Comparision with Solar Panels" two, imho, major disadvantages were left untouched: 1) no cooling for the panels, actually they are heated up by the tiles - which means a great loss in efficency and also in longevity 2) in electrical installations the connectors are usualy (in long term) the most probable point of failure - and here we have a lot of them.

The process is still wrong. You don’t NEED a cement tile backing the solar panel. The purpose of the cement tile is to protect the waterproof sheet. If the solar panel can do that alone, you don’t need a heavy, expensive, cement tile. Just make the solar panels a little more robust to protect the waterproof underlayment fabric! Not only that, the cement tiles hold heat! Without them, the solar panels would stay cooler.

I believe we need to design and build with solar in mind, large flat rectangular roofs made with metal insulated panels with solar on top. The air gap helps cool the panels and increases efficiency, holding on to tradition will only hold us back!

Killua Zoldyck Flat roofs are the worst for solar, they need to be angled towards the sun. Panels on a flat roof would need to be mounted on an angled frame, so you might as well just build the roof with the appropriate slope. Insurance companies hate flat roofs for a reason- they are notorious for leaks. I agree about concrete roof tiles- personally I think traditional slate is still a good choice- it's relatively low carbon, it lasts well over a century, and top quality slates can be reclaimed and reused. In fact, good reclaimed welsh slate tiles reclaimed from old buildings are more in demand and hence more expensive than brand new ones!

[@Wookey.]

Right. solar tiles have been around a long time (12 years?), but always significantly more expensive. Unless planners mandate them or you _really_ don't want the standard large panels they aren't very interesting and almost everyone picks the standard scheme. You can also get built-in standard panels and gasketed panels where the panels are the roof. France mandates BIPV (or did) so it's a lot more popular there.

[@gregandkaruna6674]

Do hope they are fitted with an air gap as black glass gets extremely hot! During hot very sunny days can see that getting into the home even with best insulation.

[@AnalystPrime]

@@GlenisRetiredNZ At 15W per panel it is a 13.5kW system, which can cost as much when done with panels. In theory the solar roof goes on as one build and would be cheaper than building a roof and then hiring a separate crew to install solar panels. Also, that is a tile roof and while you can put panels on one I have heard that the frames they need to use for it are fugly. Plus, why would you get a tile roof in the first place and then cover it up even if you don't think panels look bad? I don't think installers are incompetent enough to cause leaks these days, but putting the panels on frames that allow wind under them for cooling also means a stiff wind risks pulling up the frame, at which point it might go flying away if it is not nailed to your roof and could rip off your roof if it is. Many installers actually seem to advertise how they set the panels flush with the roof to avoid making them stand out, so I don't know how valid the argument about panels getting better cooling because air gets below them is anyway. TL;DR: It's never going to be cheaper than just solar panels, but if you are building a new roof you can get more solar power on it at same or cheaper price and make it look better than if you added panels.

[@TassieEV]

That would be awesome in Australia. Also preferred how they did the underlying roof stronger than the typical method used here and I'd demand they built my tile roof the same as the UK. To get 13+ kW as well on a house would be fantastic.

[@MrGonzonator]

My only concern with these is that each tile is individually glued on. How will these adhesives cope with 25 years worth of winters with frost creeping in between the layers? If even one is sub-par you have a hole into your roof and your electrical systems, and then you have to rip the whole lot off. At least with the standalone systems the fixings are under the tiles and do not compromise the integrity of the roof itself. Alternatively with the Tesla offering, the tile and panel are one and the same.

[@MrGonzonator]

Freeze at 1:46 to see what I mean.

[@DEADB33F]

This would be my main concern. If you look at 2:13 there isn't even any sealant around the hole at the back. I would at least have liked to see that gap around the junction box potted with epoxy or silicone.

@@DEADB33F exactly my concern. Once you get a roof leak you are going to need to test integrity of a large number of tiles to find the faulty tile. Also flat concrete tiles are fairly rare where I live. How flexible are planners going to be if I change my roman tiles to flat?

Another excellent video Robert - thank you! The only thing I found a bit odd was that the roofing contractor was having to cut a hole in the plain concrete tile to facilitate installation of the electrical component. This adds time, creates waste which adds cost so I wonder why they can't have the tiles made with the hole already formed as part of the casting process? I'm sure that tile manufacturers aren't doing this now because there isn't a big enough demand for them but hopefully this will change. When it does, the cost of having a "solarised" roof will reduce and so become even more of a no-brainer!😁

[@EleanorPeterson]

Hi! Sorry, I don't know anything about wiring solar panels, but I think I can answer your other question... Any rain or snow that got under a tile would fall onto the flexible membrane beneath, and run down into the gutter. That's what happens on regular roofs now if gales blow water back up under the tiles. The roof's hard concrete, ceramic, or slate outer covering is really only there to protect the waterproof membrane underneath from gales, storms, hail, ice, and UV damage. It's the soft membrane that makes a roof watertight, not the tiles. :-)

Concrete manufacturing being very polluting CO2 wise. What mitigation measures are being used by the tile manufacturers to counter excess emissions? Perhaps advances in concrete manufacturing could be a topic for a future video.

Ok, when it comes to costs, and please feel free to correct me on this: from the video, a traditional concrete tile is £1 (making it £10 per square meter). A solar tile is £30 (making it £300 per square meter). Essentially this roof is 30 times more expensive than a traditional roof. The economics work a little bit better if you compare a roof tiled with solar tiles to a normal roof plus panels BUT not by much. I am all in on solar (have panels on my roof) but I’m not sure the economics of these type of solar tiles makes enough sense. Also, version 3 of the Tesla solar tiles just got cheaper. I cannot remember the exact figures right now but I remember them being far more competitively priced compared to traditional roofs. Again, I reserve the right to be completely wrong here and I stand to be corrected.

You also have a lot of cabling. Like Tesla it might be more efficient to have 3 panels in a row for 90w, then you don't need so many connectors. If you get one poorly fitted connector then you lose the lot and it's harder to diagnose. I imagine as there's nothing behind there there should be no fault. But one bite from a squirrel and the lot might go down! At least with solar panels a fault could be diagnosed to the panel and that replaced without undermining the water protection of the roof.

The EMP (Geomagnetically induced current) (GIC) even in a major event will only be important for very long conductors, not like those you get in a roof. You won't see large pulses on the domestic mains supply either. This is a distribution problem. OK - so if you have one of the new power walls your lights might still be on afterwards if there is a power cut.

@@mikewillis1592 Absolutely nothing ? That's certainly not the position of industry experts. It's well known there have been massive power outages due to CME as well as the fact that EMP weapons are a real threat to modern society. It's a given solar power inverters will be burned out, lose their fusing, and require repair from a significant CME let alone human use of EMP weapons. Given these facts are not in dispute by anyone in the power industry it's a completely valid question...what happens if your EV is plugged into your home during a significant CME or if some nut uses an EMP.

Apparently Tesla are now working with third party installers in US, and I came across a piece from the head of (I think) Good Faith energy with a picture of his Tesla-cvered roof, and it it has hips, gables the works. So it looks as if they have progressed from simple rectangular sloped roofs

Interesting, I had only heard of the Tesla solar tiles

[@Vardraq]

There are quite a bit of solar roof tile solutions. The one shown in this video here however are the most crude solution.

Im sure i saw them in 20+ years ago, still waiting for them to be on every roof....

[@Alex-cw3rz]

The first time I saw them was well over 10 years ago 😂😂 God Tesla could make a door and people would think they were the first to do it.

[@Vardraq]

@@Alex-cw3rz well, to be fair, what Tesla does is a multitude more advanced than what I have found during my research last year and this year. Most solutions are just small panels slapped on tiles without protection; therefore easy to break. Why these solutions are so darn expensive.... I just do not get.

[@goliver3846]

I found this really quite interesting. As a slow convert I was immediately taken by the fact that you made no effort to put any costs to the extra building work required (I may have missed it) and just gave the additional cost of the tile over conventional. To convert folks like me you need to be completely transparent.

[@chrishall8738]

there are no extra costs to the building work. Roof tilers are paid to lay tiles or solar tiles, no difference. We supervise and ensure electrical connections are made in the correct manor, which is included in the cost of the installation.

[@goliver3846]

@@chrishall8738 Sorry, I understood that the roof structure needed enhancing to take the extra weight?

[@chrishall8738]

@@goliver3846 No, the roof structure is already designed to take the weight of the tiles, so we are not adding any extra loading, unlike bolt on top solar, which adds both extra static deadload, and dynamic load as wind blows across the roof.

In 2008 I project managed a new housing estate in Lytham St Anne's, building 111 social housing homes for rent. The scheme included two large blocks of 85 flats in total. All were built to Code for Sustainable Homes Level 4. The apartment blocks had solar interlocking roof tiles, provided by a UK company called Solar Century. The solar tiles were called C21E. Each solar tile was the length of three concrete tiles and interlocked with the concrete tiles and were wired in series. Like Tesla, this video gives the gives impression this manufacturer invented the concept of solar tiling interlocking with traditional roof tiles in 2010. In reality, Solar Century were doing the same, albeit with triple length rather than individual tiles, years before. We used the solar power generated to subsidise the energy used in the communal areas, to reduce service charges for lighting and lifts. From the ground, the solar arrays were virtually invisible. The scheme was loved by the local town planners.

[@chrishall409]

Thanks, I actually started with Edilians solarmax, the predecessor to c21e, and still install today, the tiles are the first actual tile size product, that is not covered with glass
