Tesla Says Solar Roof Is On Its Third Iteration, Currently Installing In 8 States (techcrunch.com) 133

An anonymous reader quotes a report from TechCrunch: Tesla is currently installing its solar roof product in eight states, according to Elon Musk, speaking at the Tesla Annual Shareholder Meeting on Tuesday. The solar roof-tile project has had a relatively long genesis since being unveiled three years ago, in 2016. In addition to having installations run in eight states, Musk said the solar roof product is currently on version three, and that this version is very exciting to him because it offers a chance of being at cost parity with an equivalent entry-level cheap traditional tile, when you include the cost of utilities you'd be saving by generating your own power instead. Regarding timelines for wider rollout of the solar roof products at the costs he anticipates, his own words probably say it best: "I'm sometimes a little optimistic about time frames -- it's time you knew," he joked at the meeting.

    This announcement also announces a deal they have with Home Depot. Just one line but significant.

    Home depot is selling the older product line but not the solar roof. That means it either isn't ready or Home Depot doesn't see any way they can sell it. When Home Depot starts showing it in their entryways that is when you will know that this project turned out to be a winner.

    As for the delay -- Musk is blaming that on all the work they had to do to get the S3 production line up and running. Actually I believe that. A year or so back he was actually sleeping at the plant to get more time to work on the problems they had.

    I wouldn't write off the Solar Roof just yet but they ain't out of the corral yet.

    • Tesla is refining the technology for the solar roofs otherwise Home Depot would be selling it already. The only reason why this type of roofing was invented was because the Baby Boomers thought solar panels looked "ugly" on their homes. Talk about priorities. Whereas the younger generation appreciate the more techy appearance, the older generations didn't care to save money on their electricity bills if it meant that big dark panels were going to be placed on the front of their homes. Elon Musk compromised
    • It's not just production of the roof but production of the batteries that caused a shortage. Even if you wanted to buy a Tesla power wall battery for storage right now you would have to go on a waiting list that might be years long because they need the battery's to instead go to their cars rather than powerwalls. So without a way to store your solar power your solar roof is pretty much useless.
      • So without a way to store your solar power your solar roof is pretty much useless.
        That depends on how much power you use, and when. Or how big your solar panel is.
        a) you could feed into the grid when not consuming it yourself
        b) you could just have a small installation, covering the AC costs during daytime, plus a little bit extra for a TV and a fridge

        90% of all German household installations have no battery, but that is because they are supposed to feed into the grid.

    • No, that isn't the news. SolarCity was going to give Home Depot a great deal, and when Tesla bought them they just wanted to transition to a normal deal at the end, not keep Home Depot in any sort of exclusive position. The interest from Home Depot was based on being some sort of premium distributor. If it is just a regular product, it doesn't warrant the sort of special branded display they were doing.

      It is precisely because it was not yet a winner that SolarCity was giving Home Depot a deal that might hav

      Huh? In a rationally run company with competent management - the only overlap between the Model 3 and solar roof product lines would be at the very top, in the C-suite. If the problems with the Model 3 caused disruption to the solar roof... Something is very,

  • Honestly, what a worthless article. If they are going to tell us that they are installing in eight different states then shouldn't they at least tell people which states they are?!

    These things are insanely expensive. Just insanely so.

    Now his 'rev 3' is apparently much cheaper. But not the language, they only are 'on par' with tiles when all the energy you save is taken into account.

    So first? You'd only want to install these, if your existing tiles NEED to be replaced, or you're building new. Because otherwise, you're not saving a penny by installing these, you're just paying for a whole new roof out of pocket, for zero cause.

    Second is, his numbers are based upon living in the sou

      What a shame if they could only serve half of the ~600k new homes per year in the US alone (vastly more globally) and the roof replacements for a similar number of older homes ;) How would they ever get by.... ;)

      (Tesla also sells conventional panels for people who don't need a new roof)

    I have need for a new roof before too long, and would love to use the solar shingles from here - they make way more sense to me than panels bolted on the roof, so I'm kind of holding out for them.

    I looked at it before and the installation is pretty expensive, maybe gen 3 has got it cheap enough to consider as a more realistic roof for most people.

    Some extra cost is warranted though when you consider how useful even marginal grid independence is, if the power went out it would be really nice to have a system like this keeping the house going. Also the fact that you generally use a PowerrWall battery with it means is has a well considered batter system and is not just solar panels providing power at the moment.

    • by Rei ( 128717 )

      Yeah, basically you have a home backup and a UPS included. ;)

      (I wish they'd give switchover times in milliseconds for the Powerwall - but I've talked to some people who have it and they've not had problems with their computers during switchover, so it must be pretty fast)

        And hopefully you have enough single player games installed when the power around you and the internet goes dow :P

      Just go with standard panels like everyone in Australia does. There you can get 6.6kW of panels with a 5kW grid-tie inverter for USD2100 installed.

      PV panels are so cheap now that everyone over dimensions them so they can drive the inverter at its maximum output under sub-optimal irradiance in order to maximise feed-in tariff revenue. (Single phase connections are limited to 5kW export.)

      • I know normal panels are a lot cheaper, but the Tesla system includes the power wall battery in the price in addition to the tie-in, and on top of that they act as for-real roof tiles that will last a very long time and are stronger than standard tiles.. also probably more insulating.

        I also am a bit dubious about putting a bunch of larger holes in the roof to hold the panels in place, seems like after ten years you'd have a higher risk of leaks from that even if they sealed them pretty well. I don't have l

          Just like anything else mounted on your roof (TV antenna, lightning rod, satellite dish), if done properly leaks are extremely rare [greentumble.com] and will show up right away.

            Solar energy is the best alternative for our daily use. But i think it more costly than our home [windowsclassroom.com] electricity. Is it true or not?
  • I'd look at other people who've tried to get a Tesla roof before you give them money. Lots of stories of Tesla taking your deposit then nothing ever happens. Also, this is probably vaporware

  • Way cheaper just to install normal solar panels on top of your roof even after factoring in the cost of tearing off old one and installing a completely new roof.

    Much of what Tesla is peddling power walls, cars..etc is not only way over priced for the same capacity it's significantly more dangerous than other battery systems (e.g. iron phosphate) where weight and size constraints become mostly irrelevant.

      Assuming you want a roof covered with ugly solar panels. Many are willing to pay more to have a pretty house.

        I don't care. I think solar panels look cool on roofs.

  • The only new information provided in the article is that Elon says the solar roof tiles are now being installed in 8 states.

    Which states? How many homes? Can ANYONE get them now? How much does it cost in either of those states. No answers because the ONLY reason the article was written is because Elon said, "being installed in 8 states."

  • Tesla would be wise to roll this out in states where all new construction houses and residential apartment buildings have solar and HVAC systems, such as California.

    Go where the regulatory infrastructure works for you, not against you.

    I'm curious how well these handle some of the weather extremes that seem to be more common now like hail, high winds, heavy snows, etc. I'm really hoping the tech & manufacturing cost matures to the point that these are a viable alternative for around 115-125% the cost of a regular shingled roof by the time my roof is ready for replacement. We had a major wind storm blow through in May that knocked power out to 90,000 houses. As I sat around candles and flashlights, I thought about how nice a solar roof would be.
    • A standard domestic solar installation, even with a battery, will not work when the grid goes down. I've just found out the reason is that the power company wants all generation off if linesmen are working on a fault.

      You can buy the correct electronics, it'll have a thing called a load transfer switch. I have one (for other reasons), it is basically a huge relay that physically terminates the connection between house and grid.

    We live in an extreme hail region that is expected to get more and bigger hail.
    As it is, we have already replaced our hail-resistant shingle roof 2x in 10 years. Come the next time (assuming we are still here), we will switch to Tesla roof. It really makes good sense.
    • Hope it works. I live in an area that can get "golf-ball plus" size hail. I'd be too nervous to install glass tiles.

    I checked the Tesla site, but there isn't any info on how the tiles are actually connected. For instance whats the voltage of an individual tile, how many can you link in series to get X voltage? Then how many of those in parallel ? And connectors...pretty weatherproof I assume. Curious about how one would go about fixing a single cell if it were bad.

  • I'm waiting for this. My wood heated, passive solar envelope house will need a new roof within ten years. Hurry up dude!
