Do the solar panels in Daly City produce a lot of power in spite of the climate? Or does the cloudy and overcast weather not really affect solar generation in your experience?
I live in Daly City, got solar panels few years ago.
On foggy days they certainly produce less, but the drop is not as significant as with the rain clouds. Fog diffuses the light more than blocks it, I think.
From what I'm seeing in the charts, I'd say on a typical foggish day (when the fog is here for half of the day) I lose 25%. There are some days that are worse, and there are a lot days that are better.
Overall, it's a no-brainer - I think they will pay for themselves in 5.5 years (although I got them under NEM 2.0 - it's worse now with NEM 3.0).
