Solar roof

edited November -1 in General
Has anyone on this board bought a solar roof? With or without a battery system?

I would love to do this to take me off of the electric grid completely. I am intrigued by the possibilities. My house has a very large roof surface area that would be perfect for a solar roof, I think.

Can anyone give me an estimate for the cost of installing one? If anyone has, can you let me know if you are happy with your decision? And does anyone have the batteries that would make your home self-sufficient?



  • @BBF,
    The rule of thumb is that you need enough solar to handle at least twice your average daily usage and storage to handle 3 to 4 days worth of electricity in order to enjoy the kind of reliably available electricity to which we've become accustomed from our very good electrical grid in the USA.
    You'll find this can cost more than twice as much as a simple grid-tied system would. Therefore, few actually do so.

    There is an initial up-front expense, but that can be financed or amortized, thing is that's all you'll ever have to pay for utilities ever again and, if you chose to, you can marginally expand your system beyond your needs and sell the excess charge/electricity to your local utility provider and use the proceeds to both help payoff your cost of installation and even establish a stream of zero labor, zero expense income that you can do whatever with.

    There's a degree of typically unobtainable freedom in that that is priceless.

    The value of energy your Solar Roof is expected to produce over 30 years is based on the average price of electricity in your area, adjusted for inflation by 2% annually. Your ability to realize the full value depends on your home’s electricity usage, amount of energy storage available, and utility regulations on solar in your area. Electricity price estimates are sourced from the Energy Information Administration and solar production estimates are based on irradiance data from NASA.

    There was an article that a solar roof costs about 65K and another 10 or 1tK for storage. Dont know if it was FUD or true.

    I only use $1000 worth of electricity a year without the Tesla. I was given an estimate of between 20-60 K for a regular tile roof replacement. The higher amount was after their was a hurricane and people were getting ripped off. Would like to get one in 5 yrs when I need a new roof, but I dont think it would be cost effective and if I plan on moving in 10 yrs I doubt anyone would want to pay extra for a house just because it had solar panels. More people would be willing to pay an extra 50k for a pool instead.

    Thanks for all the replies. I want to get off the grid completely, and 60-70K does not seem outlandish to me. That said, I don’t plan to move anytime soon, and an electricity-for-free house may be more desirable when I do end up selling. I think I will look into it a little more . . .

    Does anyone actually have a solar roof, and if so, what is your experience?

    A recent article was published recently gives a good :1 year on perspective from an actual Tesla roof owner.

    Google search for "inverse tesla solar roof 9 things"

    FWIW, I just spent 62k to have my hail destroyed "hail resistant" tile roof removed and a rubberized metal roof put on.
    So $60k doesn't sound unreasonable at all.
    (solar panels pending)

    Here is link to article @greg referenced. Interesting and generally positive summary of one year's experience with solar tile roof + PW2. With her setup she accrued an electric bill of only $119.61 for the entire year, which is not bad indicating the solar + PW2 provided most of her electricity, with minimum grid draws.

    Thanks, all!

    Yes but she did not manage to go-off grid entirely, which is the @OP's desire.
    Nor did the solar exports cover the connection cost, so there is a "minimal" Grid connection fee.

    You could overcome both those issues.

    But as with everything, there are likely more than a few trade offs involved.
