We included solar panels and a battery when we built our new house in Tokyo, and even though it’s in a quite shadowy area, I’m surprised how much power we get out of them (even on cloudy days). Switching to an EV now too. It’s an absolute no-brainer.
Only dark clouds reduce solar panel outputs. Panels don't care if the light is hitting directly from the sun or diffused by cloud, as long as sum of incoming radiation over surface is high, you get your energy
Lucky you. I tried to get solar installed but around here it’s still ridiculously expensive. Unfortunately it’s also one of the scammiest industries. I went through a good dozen installers without finding one that didn’t make me feel ripped off, and that’s even before spending money.
Anyway, government incentives expired and the prices to consumers are still so high that there really isn’t a payback period. While I understand that the market should be able to stand on its own, we should have had a few more years to get off to a good start and build economies of scale or something.
Anyhow I was looking at $30k+ to cover half my electricity usage. Even worse, none of them wanted to actually sell me anything. Even when I made it an initial condition, they all wanted to dazzle me with word salad and sell me a lease or PPA agreement (totally not a lease, bro.)
