> But Sun reliably shows up most days.

Gonna need a citation on that, where I live in the Midwest there are legitimately times where I haven't seen the sun for 2 straight weeks. Not to mention some latitudes I've lived at where the sun doesn't get up till like 9 and is already almost gone by 4.

Like AZ, CA, Texas sure go nuts solarizing. But there are plenty of people for whom that's not really an option.

Its okay, you don't need to believe it.

Solar panels work even if its cloudy: Power generation typically drops to 10% to 25% of normal capacity under heavy, grey overcast skies, but can reach 40% to 60% (or higher) under thin or partly cloudy skies.
