Cool & sunny is better.

Cool sunny days are better than hot sunny days for solar gain; don't forget to calculate for PV panel thermal loss where applicable. Peace.

You are certainly correct with that statement. Spring, primarily and Fall secondarily is where we get the best solar performance in Southern Calif. Minimal heat/cooling demand plus high solar output = lots of NET metering credits for A/C use during the hot summer.

Net metering is a nice windfall for sure. There are no utility poles running to my humble homestead. Your summertime power requirement must be significant indeed in sunny southern Cali.!
