I like the idea, but the people selling them are the type of sleazy scumbags who sell garbage on infomercials. When you have to resort to those types of tactics it's because you know the product is not worth anywhere near what you're trying to sell it for. Also, a 30 year guarantee only works if the company still exists in 30 years. Good luck with that.

Clay roof tiles never have to be replaced. I have 2 sloping roofs, one facing west and the other east. I waited until I had put up 2 rooftop dormers with flat roofs and installed the solar panels on that all facing south.

[@Myrddnn]

The only thing holding solar roofing off is the difference between R&D scale and consumer product manufacturing. They simply cannot make the tiles/panels fast enough for the demand already out there. The companies involved, including Tesla, all need to look at major capitol investment for manufacturing at scale. Tesla already knows how to do this. I think the only problem here is that Elon has too much on his plate and hasn't put the time or resources into it to make it happen.

[@michaell170]

My only complaint with your video is the touting of things like 30 year guarantees. Very few companies are around 30 years later so I would not put too much stock into those claims. For example LG recently announced they are leaving the pv panel market.

[@OtterBeSwimming]

I have been working on building a new home for the last 2 years. I immediately thought of Tesla roofing and put down a $100 deposit. They gave me a quote of $50,000 for the Tesla roof, $40,000 more than a roof from my builder. When permitting was approved I sent the final drawings to Tesla and the new quote was $100,000. I got my deposit back. I also had reached out to GAF for their solar roof. A year ago they said we don't install any new solar roofs in Georgia at this time. Then they said they would install in Georgia but despite repeated attempts to reach them I could never get GAF to respond to me. Probably too much interest though I had talked to a GAF roofer locally who said he would love to work with me to get experience installing the GAF solar roof. But the house now has a $10,000 roof on it and I will look at adding solar panels instead of a solar roof. I tried but just couldn't do it.

[@aussie2uGA]

Georgia is tough for sure. I’m in Alpharetta and would love to see some Tesla roofs pop up.

PV systems are hard to sell in North Georgia. The PV sales process can not sell their PV system cheaper than the existing power companys. We should be thankful that the dam in Buford is generating cheap HYDRO power .

[@fuckthisksksjjksdfjd]

It would if been good to get a metal standing seam room because you can basically clip the panel racking to the roof with no penetrations.

[@SaveMoneySavethePlanet]

Wonky lead times like this are to be expected for early adopters of a new tech so I don’t fret too much about that. The doubling in price from Tesla though…that seems really ridiculous. I wouldn’t think too much of it, but that company in particular seems to have encountered this with multiple products (model 3, cyber truck, etc.) This is what ultimately makes me highly skeptical of every Tesla announcement these days. They seem to care more about getting people hyped than about actually delivering on their promises. I’ll gladly buy any of their products once they’re actually on the market for a while and have a proven track record, but I won’t be preordering their stuff any time soon.

This panel can put out close to 100 watts kzbin.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

[@GeekIWG]

Traditional solar panels have the advantage of allowing you to more easily start small with just a few panels, and then add more as money becomes available.

[@SaveMoneySavethePlanet]

Yup. Also, you can add a bit more if your electricity demand increases. Like if you switch to an EV or an electric range/oven. If the efficiency rating of the tiles were the same as the panels then I’d be a bit more excited about them.

[@paulogden7417]

This notion is complicated by the permitting process, the utility approval process, and the sizing of the feed wires to your panels. Its not too easy to just add a few solar panels even if you do it yourself.

[@andydimezza2229]

That’s true for most people, but for farmers and businesses that usually have multiple buildings but limited land to put solar on, roof solar is a great boon… when it becomes available…

[@redtankgirl5]

I live off grid in Canada and when deciding on my solar I had to put in many considerations. One of the factors that was a deciding one that I feel was of high value when it came to getting the full production all year round. I pole mounted my solar panels for easier access to clear snow in early morning and fill battery banks by early afternoon on a not optimal sun day. If you have some land and you live where snow will be an issue for many months I recommend access to those panels.

[@UNUSUALUSERNAME220]

Great point. The insistence is that ALL of these systems NEED to be on the roof, or a part of the roof. If you have limited space or building restrictions that may be your only option. The panels that everyone thinks are bullet proof and tough as nails, are fragile (to an extent) and would be easier to maintain if they were on the ground at a manageable height. These systems serve you best when you have the space and the knowledge concerning the maintenance and repair or replacement of them. It sounds like you have what you need, where you need them. If most people who thought they knew alot about these systems found out how little they actually knew, it would be a rude awakening for them.

Years ago when Tesla had their calculator website it was estimated my Tesla roof would cost $110,000 in sunny south Florida. For comparison, an architectural shingle roof was $16,000. My yearly electric bill was about $2k a year. I bet my insurance company would like a chat with a new $100k in hurricane country. Even my property tax office would probably want a chat about a $100k improvement to the home.

[@geraldfrost4710]

So, $94k investment to yield a $2k benefit? How much extra power would you sell to the grid?

[@barongerhardt]

@@geraldfrost4710 A lot depends on the roof size, but angle and obstacles are a factors too. Some quick math, Florida power at $0.12/kwh comes to about 45 kwh/day. Given a 5 hour/day solar equivalent, they would need at least a 9 kw system. With the losses of ac/dc conversion, storage round trip, ... another 10-20% should be budgeted. The video quoted Luma at $4.50/w. For that price the roof would be around 22kw. Call it double what is needed and sell the rest back. You aren't going to get the same rate for net negative power, nor get negative taxes and fees. Say you get $0.06 / kwh, it would be worth about $1k/yr. You will still need to make up a base hookup fee, so that might cost $200, or so, per year. Year end net should be around $800, with very large error bars.

[@internettoughguy]

So you basically don't break even until 55 years in and even then...you'll need to replace components after a few decades. You won't recoup any of your investment within your lifetime. Seems like a waste of money to be honest.

[@errcoche]

Flying car anyone? I think it should be possible to better integrate conventional panels into a roof. My roof is basically an asphalt membrane with concrete tiles over it. Those concrete tiles act as a shield against UV and abrasion damage for the membrane. Water will largely run over them but they are certainly not a waterproof layer. I cannot see why they can't be supplanted by solar panels. The issue might be with a need for free air flow under the panels but that should be achievable. The panels should be able to sit a little bit off the impermeable membrane. American house design needs to change to make sure there are ample, clean roof areas facing South, and potentially put in panel standoffs as part of construction.

[@andycanfixit]

Had to replace a roof last year, still no good options for an affordable solar roof and I have plenty of land for ground mount so all my solar is ground mounted. $8k for a new roof, was installed in 2 days with a 25 year warranty. 10kw of ground mounted solar installed myself for less than $4k and maintenance is easy. For those that only have space for roof mount the prices still need to come down but a new standard roof and standard roof mounted solar is probably cheaper than any of these solar roof options until the pricing and install becomes more mainstream. The pricing is still very much early adopter territory.

[@fastinradfordable]

Here in Cali a standard metal roof install is “$1500/ square” God knows what solar roof would be. We have off grid. Panels up on the hill. I live in a geodesic dome and only a few panels do more than I need, even in the woods with intermittent shade all day. I like the shade

[@EileenTheCr0w]

Ground mount isn't practical for anyone on less than a multi-acre property, and honestly it's still kind of problematic for other reasons even if you do have plenty of wide-open unshaded space. Honestly I'd recommend putting it on anything solid and elevated, even if you have to build a whole new shed, barn or awning to do it. Right now it depends where you live, but a solar roof is roughly the same price as a roof + solar in my area. They need to bring costs down enough to compete with those people pondering an upgrade on one or the other.. like people that want solar but their roof probably has 5-10 years of life left, or people that just need a roof and can look at it as a chance for a discounted electric bill too. Right now it feels a bit wasteful to make the leap.

[@andycanfixit]

@@EileenTheCr0w I only have an acre and a half and even with that it's plenty of space but obviously ground mount doesn't work for everyone. I would also need to remove 3 or 4 trees to do roof mounted and I would rather keep the trees. The shade they provide my house is worth it. Cost for ground mount framing doesn't have to be that expensive depending on where you live. I used helical screws so no concrete involved and it can all be easily removed if need be down the road and recycled.

If you're in a rural area, don't stick the panels on the roof. Rural implies that you have open land. Install them on unused land, and add a power shed. That's a shed where you install your inverters & batteries. Also, you can use lower cost solar panels, and older & cheaper batteries. Yes, they're bulkier, but its not moving, so who cares. Its all off the shelf stuff. And people in rural areas know how to use tools, so there's savings on labor cost. Do it yourself. Bet you wish they still had shop class, in school.

No need for batteries, though, if you’re connected to a utility. For most people, I’d advise getting a simple, grid-tie only system. If money isn’t a concern, or there’s high, time of use utility bills, the newer, smart batteries could be worth looking at.

@@adlockhungry304 oof. I can understand why they do that, the huge relays can spark sometimes, but ouch. Plus as wildfire seasons get worse and worse with the whole climate thing that’s just going to happen more and more :( In the UK where I live wildfires of course not a factor (…yet?), although the feed-in tariff is 3-4p/kWh while the usage tariff is like… well it was 12-15p but recently it’s like at least 20. So if you have enough battery capacity it can pay for itself versus the tariff disparity, plus of course you can still get feed-in payments when the battery is full but the sun is still up. But regular power-cuts is pretty much reserved for the super-rural houses (of course that’s still a sizeable number of people it could help; even keeping your freezer from thawing in a powercut can save £50-200 in groceries after all).

@@fparent, From a purely design and practical application standpoint, the GAF energy module seems promising because the wiring is accessible from above. A tremendous weakness of most solar tiles is that they’re plugged together under the tiles. This makes troubleshooting the electrical, replacing faulty or damaged wiring, or replacing a faulty module much, much easier. There are still some downsides: A). Who the heck is GAF energy? What does a 20 or 30 year warranty amount to if the company is here one day and gone the next? B) If GAF (a name that seems doomed to failure, btw) does stick around, are they really going to maintain enough back stock of their original product to replace like for like when honoring their warranty 20 years down the line? It’s very possible they could do this by making sure their new products follow the same mechanical form factor and don’t stray too far off the same electrical specifications, such that they can send the current model they offer in place of your faulty, older model.

You're in a great spot. Looking for land and the home hasn't been designed/built yet is exciting. I work for a company that designs high performance homes (think Net Zero) and does solar. The envelope of the home for efficiency is so important. When you start talking to builders the make or break areas of your home are going to be the foundation and the roof. Most homes are built with bad Thermal Bridging. So even if they have insulation between the studs the heat/cold is coming right through the frame and roof. When the wife and I build a home the foundation and roof have to be thermally bridged. The expense there pays off in needing a smaller HVAC system, less solar panels and more comfortable environment. A lof of home builds here in Arkansas are going to with higher end metal roofs so that they don't need to factor in a roof replacement. Co-worker just did a ground mount system since he's got the yard for it. New home build would be pretty trivial to trench from the ground array to your meter. All comes down to the aesthetics really.

@@ToddRafferty My install was completed in November. One major thing about the solar roof is that the snow slides off the roof, so I have mini Avalanches when we get lots of snow. It can be loud/alarming, but it is also a good thing since a covered up roof wont produce electricity. The pitch of my roof is not steep at all, so if you had a steep roof pitch, I'm sure the snow wouldn't build up as much and would slide off sooner. But going with the Solar roof I think I was able to fit a larger system on my home vs going with traditional panels. All in all, I've been very happy with my systems performance so far.

Good video for alternatives for Solar Roof's. We installed the Tesla Solar Roof v3 and Powerwall system as our roof needed replacement after 27 years of GAF shingles. Took two weeks for old roof removal and install in July 2021 and received final PTO in Feb 2022. Working well so far.

[@JBoy340a]

We are happy with our Tesla Solarroof. It produces a lot of electricity and the cost was within $1000 or a replacement tile roof, which is the standard in our neighborhood and was the target from the beginning with the Solarroof. We also added a couple of Powerwalls for which there was a discounted install since they were installing the inverters and solar wiring anyway. So far the roof and Powerwalls have performed as advertised and reduced our power bill dramatically. We pay about $30/mo, most of which is the grid interconnect charges. In previous summer months, we have paid close to $500 because the high temps drove us into the higher cost tier rates. The installation was done well even though it was started in March 2020 right before the pandemic hit and the county stopped all work mid-install. Thankfully, solarroof installs start with putting down a waterproof membrane, and that finished install just as the stop work order came down. After a month they let the Tesla team come back and completed the installation.

For me, the lead time for thing job was about 3-5 months. lSolar roof is in that range, then that’s also a good alternative. Why didn’t I get a solar roof? I wanted one but I really like the SunRun offer and garuntees. Also during this time, the solar roof didn’t drop in price like they did at the end of 2021. So my opinion: get a metal roof with solar panels, or a Tesla Solar Roof. They both have a longer lasting time ( frequently longer than the lifespan of the buyer) than buying composite shingles.

Good video, thanks for showing multiple options and being level-headed about the pros and cons. Additional point: There is no air space between the solar tiles/shingles and the roof. This overheats the structure of the house and increases AC loads. Solar panels allow a few inches of air space and actually cool the roof, reducing AC loads. This has been documented in a study (San Diego State U, I believe) as reducing AC costs by about 5%. So it's hard to justify buying a more expensive roof, with more wiring connections (points of possible failure) and increasing the heat load on the house, compared to solar panels. It can make sense when you must get a new roof, but even then, still hard to justify. If you don't need a new roof, I can't foresee the situation in which I would recommend it.

Solar PV should be the last option, in terms of ROI (if we're gonna play that game). Most energy pumped into homes (80-90%) is wasted; thus most of the PV production is wasted. It's like driving around with leaks in your gas tank. Energy efficiency has much faster "payback" than PV (plus all the additional health, comfort and resilience benefits); and most homes lack the roof space and orientation required when systems have to be over-sized to account for that 80-90% waste factor. Without efficiency measures, all the worry over PV is just putting band-aids on a leaky boat. Maybe that could be a discussion for one of your videos.

[@charlesbyrneShowComments4all]

If people would properly install an inexpensive radiant barrier in their attic and add a little more insulation to the attic, add thermal curtains, properly seal their doorways and entrances, heck even gradually replace older windows with more energy efficient rated ones, have their water heaters on timers, empty their water heaters twice a year to remove sediment build up they would see some savings. The best part is these things can be done gradually with lesser costs.

[@arzan87]

Is there a practical reason (other than that mixing electricity and water isn't necessarily a good idea) why photovoltaic-thermal hybrids aren't more common. Especially in hot sunny climates? If the panels loose efficiency when they get hot, why not integrate a cooling circuits to heat, or even just preheat water before it goes to a boiler? Granted this would increase the cost of a panel, but you would potentially also need less of them. It varies by season obviously but I estimate that around 50% of my electricity goes to heating water. So Instead of say having two PV panels, one which is just heating water, you could have a one single panel doing both while potentially increasing both the efficiency and lifespan of the PV cells by keeping them cool and reducing thermal cycling. The 2=1 math here is obviously a gross oversimplification

[@someweeb3650]

The cost per wh isn't going to be good in such a system. You can also just generate electricity directly from the heat (or I should say, heat differential) like what an RTG does. Again, neither systems are useful unless you have obscene money and want the single most efficient system for the sake of efficiency.

[@TheOleHermit]

Glad to see the technology improving and becoming more cost effective. But, black shingles, directly attached to the roof, with no thermal barrier, during 110 degree AZ summers is a deal breaker, IMO. Now, expensive EPF insulation is required to compensate, assuming that there is an attic with inside access to the rafters. IMO, roofs are roofs and PV panels should be mounted on solar trackers for maximum efficiency. The best option would be a solar carport with a tracking array to shade and protect vehicles from the elements. Otherwise, why can't PV panels be white?

While solar install @ $50k for 15 years is $277/month, and that's not counting having a battery backup which can add an extra $10-$15k, so I'm paying more per month and still losing power during a blackout, so I'm seeing no benefits and more cost. Since my state and county require me to stay tied into the grid, I don't actually get refunded for the excess power I output for them, I only get credited for when I'm not overproducing.

We went with an upgraded class 4 impact resistant shingle with a 20 year warranty with a total cost of $18,300 (39 square). Fast forward two years and last Summer we were approached by a company (Everlight) to add PV Solar panels to our roof. These panels would go over our existing new roof. I called my roof installer and the solar panel install would void the warranty in the areas where the PV panels were installed. Now this system would not store the energy onsite it would sell the power back to my power company (Xcel). Some months, between the monthly payment for the panels and our Xcel bill I would come out even, some ahead (get a rebate or credit from Xcel) and other months (likely Winter with less daily Sun and more demand to power the heating system) we would have a Xcel bill albeit smaller. The solar array would have been $25,000 hoping to get $6,500 back in a rebate. The fact that the install of the array would void our roof warranty and the fact that this area does get damaging hail we chose to not move forward with adding solar at this time. We believe that the panels will become more efficient in the future thus needing less roof area to power the homes needs. It was an interesting experience walking through the process and we seriously considered adding the panels. I offered to simply add an array on the 3.5 car garage alone but Everlight didn’t seem interested in a partial power array.

I added solar panels with my new roof a couple of years ago. I'm in Minnesota. Summer air conditioning is fully paid for by the panels; winter is a different story with snow coverage. I have to clear some of the panels on the east side of my hipped roof since the panels do not come to the edge of the roof. Snow piles up below the panels and has to be removed to get the full solar gain. Not a big deal with a roof rake. It has slowed my transition to electric heat though.

[@Cee64E]

How about looking into NON PV solar home products. A gentleman I used to work for used to heat his home with a passive solar system that used a cinder block wall in a sun facing solarium as a collector that had air flowing through it, and through a large gravel heat-sink under the wall, to provide for some of his winter heating. If I remember correctly, his cold air returns to the furnace went through these spaces. The air warmed going through the block wall during the day would "load" the gravel heat sink, and pre-warm the air going to the furnace. The thermal mass of the wall and heat-sink would keep working overnight. I've personally used a flat, glass-topped box and coiled tubing to make a solar pool heater. Surely there have to be more ideas to use solar at home than tens of thousands of dollars worth of silicon and electronics?

I was so excited to learn something from this video (as a solar roofing specialist in the residential market) and walked away so incredibly disappointed. Every single positive thing that Matt has to say about "solar shingles" or whatever we're supposed to call them came from a sales brochure. I sincerely challenge Matt to prove me wrong and show me a single "fact" about the efficacy of this roofing material which didn't come from the person trying to sell it. Every "solar roof" technology on display in this video requires A PRE-EXISTING ROOF ON TOP OF WHICH the "solar roofing materials" will be installed. If you aren't laughing already, buckle in. Yes, the "solar roof" can only be built upon an existing "normal roof". If you don't believe me, just look at the images of the roof installations on display in this video. The narrator says BS like "easier to install" while showing you a video of not one, not two, not three, not four, but FIVE installers on a very small roof, with yards of wiring spilling out into every direction, confidently telling you "SEE?!?! I told you this would be easier than just installing a regular roof". Oh, and at the very same time, the narrator fraudulently implies that the price you pay for the "solar roofing shingles materiel" or whatever includes the cost of interconnecting all of this PV equipment into the grid, such that you can actually do something productive with the solar capacity. False. So basically you need to have a fully intact roof, then you get to install your fake "solar roof" on top of your "real roof" (which is literally identical in function to putting solar panels on your roof, except it's more expensive and less insurable, but who cares about my opinion), and then you have to pay to wire that "fake" "real" roof into your home's electric system. But when I say I'm disappointed, it's not because people like Matt are so obviously and completely duped by sales pitches. It's because Matt clearly doesn't care at all whether he's been duped or not. It's clear that he simply prefers the easy and comforting reality of the salesmen, where all of the fantastic breakthroughs are "just around the corner" and "any day now" the amazing promise of all of these mind-blowing technologies will be unleashed "as soon as we give these very trustworthy and definitely not biased entities the money they so desperately need in order to overcome their inexplicably high customer acquisition costs which are definitely one quarter the cost of an entire residential solar installation," and I am definitely not literally laughing out loud at the notion that one quarter of the entire dollar cost of a residential solar installation should go towards "customer acquisition" costs. And no, just to confirm, I am still not laughing at that utterly absurd claim.

[@monicareid8858]

We needed a new roof badly, love the idea of solar, and in NY, the tax incentives on paper outweighed the value of an asphalt roof. Breakdown: new best asphalt roof with highest warranty: $9,500. Tesla roof after incentives: $14,500 that came with a $10,000 Powerwall battery. That Powerwall can run our house’s electric all night until a good part of the next day in sunny spring-to-late-fall days, so we rarely use the grid for electric until winter, where the 9kw system doesn’t get enough sun (Central NY) to charge it fully-or it’s covered in snow. It was a no brainer-on paper. In reality, customer service to rope you in was excellent, until you started having questions. I’d get no answers or contact from my email handler for months as I waited for email handlers to get replaced about seven or eight times in the course of March 2021 agreement to September 15 2021 installment. Then the construction team were ready two weeks ahead of schedule to install before I got certain answers to important questions-like cost after incentives, and a few others. I had to sit in front of the contractors and fold my arms and say until I get these answers, you can’t start. Suddenly, I had a new handler, and all the answers I needed. We proceeded to begin. The team was amazing! Fast, courteous, efficient. In the end, a wonderful experience-the solar roof went on, and pow! I has solar energy powering my Powerwall! The team handled final things while I was at work, packed up and left. Then I came home and did a walk-around-and looked up on the sides of my house-. They had removed-hand-cut and butchered metal trim on both sides of my house. It looked horrible. Scissor marks at the corners where they used to be wrapped protectively around my trim. I called the main contractor several times and finally got him on the phone. He gave me a song and dance, but agreed to come back and fix it-which he did-sort of-but did a horrible job that looked nothing like the original. I refused to pay. Tesla threatened collections until I kept calling over and over, sending pictures of what they did to them, and photos of the original trim I had to dig out of the dumpster to get. Finally, they stopped collections and agreed to fix my trim. Then I realized-my original trim stuck out about an inch and a half in 3-d relief and wrapped around a board they removed. If the original trim was to go back up, the Tesla roof would not cover it. The contractor team had shortened my entire roof by about three inches on both sides, and covered it up (poorly) but ripping my trim off!! So I’ve gone all winter without this fixed, and without paying (though paying interest on my loan to get the roof) they just got a local company to give an estimate to repair the trim-and he confirmed they shortened my roof, and there’s no way to get the trim looking like the original-which matched the rest of the house trim-but they could make it more secure and look better than what Tesla’s guy did. I love my solar, but am very disappointed in this trim mess. It’s been a nightmare of endless calling and taking names and documenting everything, and being terrified of being sent to collections when I have the money-but just won’t pay until they fix their mess. One local guy had Tesla install solar panels, and paid, but due to some hiccup at the grid connector didn’t have solar for over six months and kept getting the runaround by Tesla’s customer service team. So I knew not paying was the only leverage I had to getting this matter addressed. So it’s a year later, start to finish, we’re still not on a two-way grid bubble (so extra energy can go to the grid and make me money) since I haven’t paid, tax time is now, and I get to see if the $11,000 incentive really is what they claimed, and my trim will never look the same-but is on the works to get improved-ish. I’ve learned to let go, as winter prevented any further work on the matter. In short-Tesla needs to improve customer response time via email. There is a labor shortage due to Covid, so I get it, but their lack of response time has really caused unnecessary stress. That said, they ARE addressing it, and my issue has gone up the ladder, and it’s being handled (as I got their attention by holding back on paying). Hopefully, this will be resolved soon. I love the roof and Powerwall, but I’m rather over the whole mess.

In my opinion, modularity is the best route. I have a start up company that is producing a housing unit for solar panels themselves. The housing unit itself is made in response to the architecture of the roof. It reinforces the current structural integrity and while initial installation maybe a bit high, being able to add or remove panels from the housing unit is going to make future upgrades/fixes so much easier. Cheers to hopefully a future that we can be proud of!

The roof on my TX house is now more than 17 years old, and is getting close to replacement time. All of my neighbors have gotten new shingle roofs in the past two years, no doubt capitalizing on hail storms to ‘find’ damage to their roofs and have insurance cover some/all of the replacement cost. I have considered solar roof shingles instead of panels, as I think it’s a better overall system, and it looks less disruptive than solar panels. Most of my roof faces East and West, not South, so having solar shingles would probably be better overall, and generate power throughout the day. Plus, I would have no solar panels visible from the street (the West facing part of the roof. Thanks to this video, I have more info to use when investigating whether solar shingles will be worth it. And if not, then I’ll put another standard roof on the house. Here’s hoping for another hail storm soon. ;-)

Thanks for the video Matt! I wanted to share my miserable experience in installing Tesla solar. While my installation was done within 2 months or so after putting the request. It took almost 7 months to get the system working after installation! And yes, I paid the entire cost for the panel + 1 power wall, which was almost 29K in 2021. Tesla just keeps you in dark and never calls or updates anything. During installation they told me that it might take up to 3 months to get the permission to operate, but even after 4 months nothing happened. I got really frustrated and after almost 10-15 calls to their support I finally got something going. Even after that point it took another 2 months and my project manager was completely useless. They put the blame on my local energy provider (PG&E) in my case. After the permission was granted after 6 months, I thought I finally got the system working, but no! There was another issue, the system was not connecting to Tesla grid and my tesla app was not recognizing the system. It took another month and multiple calls to diagnose the issue and the support system is totally broken! Well, finally after 7 months now everything seems to be working fine. While I really like the Tesla solar app this was the most miserable experience I ever had with a company. I am not sure how other companies are, but if a trusted brand like Tesla is doing this, it is miserable. At one point, I was even thinking of consulting a lawyer suspecting a scam!

How do you deal with a roof problem, like a leak, if you have solar panels installed? Do you have to call the panel installation company to remove them, probably a minimum 3-4 weeks delay, and then a roofer, and then the installation company back. If so, that could be a pricey and lengthy repair job.

[@peterbarnard6396]

Thank you. We have two older homes on the east coast. One is in a historic district, the other has a complex mansard roof with dormers and multiple slopes. Standard solar panels aren't really an option for either (historic district won't allow them, and the mansard doesn't have enough large flat surfaces to mount panels), so I've been tracking solar shingles for a while. Currently, I'm in the "lets see if we can wait ten years" camp.

[@maxwellhouse750]

I had my roof for about 17 years. When it came time to replace, insurance covered 60% of the cost. I paid $4,300 for dimensional 125 mph regular shingles. I know a solar roof on my house would easily be $50K. My utilities run about $3.5K per year to be quite comfortable so the amount of utility money per year is not astronomical. When you consider investing some of that difference over time versus taking a loan and paying interest, I just cannot justify it. Even if I had the $50K+ up front for solar versus just investing that money, I doubt you could ever come out ahead unless the investments did very lousy for a very, very long time. I am definitely decided on keeping my $4,300 lifetime roof with 10 year shingle blowoff guarantee. I also have zero maintenance and zero monitoring. I just don’t have to worry about my roof in general which is good piece of mind.

[@michaelsmithers4900]

I think I’d prefer a “solar parasol” mounted a foot or so off the roof on a more robust frame, possibly to the groung around the edges, only on the south face. This would shade the house keeping it cooler. Also it would reduce the need to leave gaps for plumbing vents.

[@MrVelociraptor75]

I actually like the look of 'normal' solar panels too. It would be awesome to have panels of different shapes, to better cover the corners and peaks of a traditional roof though. A big part of the efficiency advantage that 'normal' solar panels have is the heat difference (as mentioned in the video). They have an air-gap underneath them that is very good at allowing the heat from the panel itself to dissipate. The other (rarely considered) advantage that this brings, is it actually shades the roof itself, reducing the heat build up that gets into your house's roof cavity (not an advantage in colder climates, kinda the opposite to be fair)

[@falkenherz1708]

I agree. Plus, the "idea of unobtrusiveness" seems to be just a matter of habit. I have encased my roof with normal on-roof panels and find it looks awesome and high-tech. So far, no animals made nests in the space between roof and panels, even though we do have some critters around here, and it is installed for two years now. Also, the additional blocking of sunrays helps a quite bit during summer.

[@chrury]

I'd like to clarify. While coverage is the main factor of your system power there are a couple engineering requirements that need to be considered when installing panels. First you have the national requirements for first responder safety. Solar panel systems are required to have at least one three foot gap of roof on the side and three foot of gap on both sides of the peak for firefighter access. I'm not sure how solar roof tiles get around this, the tech is new so the codes might need updating. The second thing solar systems need to consider for coverage is panel size. A system's performance is generally limited by the lowest performing panel. That's one of the reasons shading is such a huge deal when designing a system; a panel in a system with a shaded panel will be limited until the shaded panel is also in full sun. Similarly, different sizes and shapes of panels can drastically complicate the calculations required to get the most efficiency out of the system. Then you have the manufacturing costs to produce panels in different shapes and the extra install cost of the additional racking and positioning. It's a decent idea but the cost per W of the system would go up for limited returns.

[@MDP1702]

@@chrury Regarding the shading, that is why some people might use micro-inverters, which reduces the impact shading has on the system as a whole. Though if you don't really need it, you'd avoid it due to extra cost obviously.

Panels are clunky solutions to the problem of buying a "used" house, like seat covers on a "used" car. We wouldn't want those same seat covers on a "new" car. just wouldn't make sense. As new homes are built, they'll be more efficient (not wasting 80-90% of their energy to begin with) and PV roof will do two jobs in one, like picking a new smart phone instead of an old "not smart" phone because... why wouldn't you?

[@MDP1702]

@@DK-vx5co I don't really see panels as a 'clunky' solution, after all panels are used nearly everywhere (even in new builds) currently. The only reasons you might get a solar roof instead of panels are: 1) esthetics, which most people will not really care that much about, at least none that I know. 2) roof geometry doesn't allow for many panels. 3) this is the most important point: cost. If a solar roof is cheaper than putting up panels, ofcourse people might go for it. But if you don't need a new roof roof, there is no need. And if a regular roof + solar panels is more cost-effective, people are unlikely to go for the solar roof option. The smartphone example doesn't really make sense. That is similar to saying "well, you'd pick a new roof instead of on old one, because why wouldn't you?" If my old smartphone/roof is still fine, why would I need a new one? You'd not compare an old roof + solar panels with a new solar roof (otherwise the former is most likely less costly), rather a new roof + solar panels. Also I don't know where you live, but where I live roofs tend to not be replaced before solar panels reach their end of life, 45-70 years is likely a good estimate for when roofs are replaced here, with a solar roof it would be around 30-35 years. So imo if the costs aren't in favor of a solar roof and my roofs geometry allows panels, I'd go with the 'clunky' panels.

[@cakeshoe]

Layman’s question here: I understand that these types of solar panels become less efficient the hotter they get. I have heard that on several sites but no one has explained precisely what that entails. So isn’t there some way of passively cooling them, such as having a bigger cavity directly below them in order to circulate air flow? Or is this ‘heat’ more concerned with the temperatures within the layers of the panel itself (precluding airflow as a cooling solution)? I live in the tropics; I’d be really interested to hear about the efficiency of solar panels + their efficiency when in temperate climes versus tropical climes.

[@p.chuckmoralesesquire3965]

this video is just lazy nerd click bait LOL

[@chazdomingo475]

You could build for airflow underneath them, but that would add significantly to the cost as well as the profile of the roof. This is just another reason why solar roofs are a dumb idea. Install your roof, then install panels on it so you can optimally position and airflow comes naturally, instead of having your panel be both a power generator and watertight barrier.

I’ve had solar panels installed on my roof approximately 5-6 years ago. I truly believe in clean energy and our country’s independence on fossil fuels. Ironically, now with the price of oil going through the roof my decision to have these panels installed has been a godsend. I live in New York and our electric rates have gone up 100-300%! That’s insanity! I received my electric bill this past week and it was $0! In fact, I still had a credit of several dollars. My next door neighbor recently contacted me to inquire about the panels. Apparently, she had received an electrical bill that was over $1,600! That’s absolute insanity! For those who are on the fence about solar systems, and they can have their own issues, the fact that they offer a measure of energy independence, along with a cleaner alternative, was for me a great selling point. Current world events have finally proven me right. I would caution people planning to install panels that you should install a new roof prior to installing these panels. I recently paid over $5,000 to have my panels removed and reinstalled in order to replace my roof. Solar panel leases usually run for 20 years. Quality roofs will last 20-30 years. For me that was a costly “ lessons learned “ scenario. So be forewarned!!!

They would have people lining up to buy those homes and become part of a Tesla designed community. Incorporating bike paths and trails, some apartments and condos with solar canopies in the parking lot for EV charging and a business district that you could ride a bicycle to pick up groceries or do light shopping. Some developer should jump on this and team up with a winner.

[@TheBrewjo]

I think the way to go is developing solar tracking and reflectors with traditional PV arrays. You get a better window of peak power with tracking, you get a substantial boost in power from reflectors (which would be great for overcast days/less sunny areas). The burden would be to develop a smart controller to manage the load on the structure and depending on the roof reinforcement may be necessary. But on the flip side, install could be down to half a day- if the system can be delivered on a pallet, final assembly on site and a light crane to place it on the roof.

Solar roofs have been around for a long time. I remember looking at solar roof products 10-15 years ago when I put solar on my camper. The company made thin film solar on an aluminum substrate. I think the company was one of the pioneers of thin film solar. They had two roofing products. A 3 tab asphalt shingle, and standing seam metal roof. The standing seam solar panels came in a roll with a sticky back. All you did to install it was drill a hole in the a roof panel for the wire. Peal off the back. Stick it between the ridges on the metal roof. Because they curved, I was think about sticking them on the curve of the camper roof. California started using the solar shingles on park/beach small buildings like toilets to avoid vandalism that the regular more visible solar panels attracted. The company was Uni-Solar. They where founded in 1960 as ECD. I'm not sure when they started making solar roofing. My guess is before 2000(They say 1997). There sales peaked in 2008 as the largest thin film solar manufacturer in the world. They went bankrupt in 2012. So when Musk acted like solar roofs was a new idea, I rolled my eyes. I have to admit that the Tesla solar roof looks better then Uni-Solar roofs did. An interesting aside, another division of ECD, Ovonics made the NiMH batteries for the EV-1.
