Tesla's Solar Roof

I went by their website. You just enter your address and you get an instant quote. $100K for 50% coverage of my roof. Then they do a sham calculation to show your savings over 30 years. $12K just for 2 batteries (ok, they're big batteries), but says nothing about the fact that LiIon batteries have an at best 400 cycle half-life and you'll need to replace them every 2-3 years. So in 30 years I'd end up spending closer to $150K or more. That's almost $500 a month for 30 years. I pay that much maybe during the hottest month of the year, but half that the rest of the months. Nice little scam.

    As they say, a fool and his money...

    The funny thing is, they put 50% active panels and 50% inactive panels. The inactive panels won't generate electricity, they're just there for aesthetics. So I played around with the quoting tool and checked to see how much it would cost to cover my roof with inactive panels. $34K So that's $34K for just a new roof that does nothing else than regular roof tiles.

    And that is IF your electrical utility will buy the electricity.

    What seems to save money while providing a benefit is the solar systems of "off the grid" homes and in particular buried homes. No electricity for HVAC and very small heater.

    Liked this guys setup using buried shipping containers. Also used "solar tubes" for interior lighting.

    The Tesla system with batteries is essentially an "off-grid" system that works day and night. It CAN sell power back to the power company, but only if all the batteries are fully charged and house demand is less than the panels can provide - and then the electricity is truly surplus to the home.

    The most common rooftop solar systems don't have batteries, and don't store power for use at night (or long storms). They provide a constant supply to the house, with any surplus going to the power company. But at night, the home is back on the company's grid. That's where they get ya - they charge phenomenal rates to folks who have solar, especially during evening high-demand hours.

    Our Rocky Mountain company recently said it wants to charge solar owners not the usual few pennies per kilowatt hour for evening use, but up to eight DOLLARS a kilowatt hour! People would end up paying more for their monthly bill than those without solar!
    I may be a bit crazy - but I didn't drive myself.
