    Love those tiles, and my house could use a new roof. These would be great.

    I wonder if the Glass Black tiles work better then the slate look.

    How long before the thing pays for itself?

    Still it sounds good, but I suspect it hasn't been tested for long term.resilience against the seasons and elements? Or has it been?

    I don't know, but it says with 30% of the tiles being solar, it is cheaper than a metal roof, and will last a lifetime longer.

    He quotes $11 per square foot for glass tiles (not solar cells),
    saying this is less than a conventional roof. Seems awfully
    high to me. Asphalt shingles are about $1/sq ft. Metal roofing
    (what I'm having installed now on several buildings) is comparable.
    What gives?

    It seems awesome. I can only assume they sacrifice virgins as part of the production process.

    I wish I could buy that, but it's too pricey and we're going to move sometime in the next few years. I really like the idea though! Maybe someday in our future home we can do that.

    The claim of low material cost is still bogus, even considering infinite life.
    An electricity generating roof could have some applications for wealthy
    off-the-grid types though. I'm sticking with the steel roofs I'm currently
    buying.

    I agree with you. The upfront cost is exhobitant and will immediately make it unaffordable to a lot of folks. But it comes with a lot more than a steel roof does. Including the cost of replacing the old roof, permits, installation, maintenance, tax credits and (depending on what you get), the ability to sell excess power back to the grid. Which is all pretty nice.

    I've switched to steel because installation cost is lowered by going directly over old shingles,
    & by its long life (well over 50 years). Solar power generation is attractive, but the economics
    of it are far from cost effective when one considers capital cost, life, maintenance, & the cost
    of borrowing money.

    Permitting, maintenance, lifetime guarantee et al are already in the total cost, plus lots of ways to reduce the total cost through everything from financing to government incentives. Which is all not that different from Tesla vehicles which even my middle class dad was able to get. (In that it also has lifetime charging, maintenance and more with the total car cost and got some of the money back through incentives.)

    I'm not saying it's not expensive. Just that it's set up in a neat way to make it worth the cost.

    Without quantifying the cost effectiveness, it's all smoke & mirrors & unbridled optimism.
    Tesla cars don't look very affordable to me. Toys for rich boys.

    Pretty well quantified in the Forbes article.
    Again, my dad isn't rich. He's a middle class software engineer working in Wilsonville, Oregon.

    There is the ethical problem of accepting such heavily tax-payer subsidized products also, I think most people deep down prefer to pay for things themselves rather than force their neighbors to..

    Other than that, the most efficient solar power gathering roof installation, is called a 'skylight' !

    No problem with that, but they are paid for by the rest of us

    It didn't provide any analysis.
    For example, infinite life (so long as Tesla honors the warranty) has a net present value which is a function of the assumed interest rate. Didn't deal with it. Maintenance costs of the whole system....didn't deal with it.
    A new Tesla is a whole heap of more money than other cars. Sure, a middle class guy can buy one. But the same guy can also buy a Prada briefcase. Doesn't make it cost effective.

    Tesla likely wouldn't exist without 5 figure subsidies for each car by taxpayers.
