Reply #1: if they put em in the Central Valley they'll be in good shape except the 2-3 months of tule fog

we had solar in the Central Valley and it did awesome, we never installed a 'conventional' hot water heater and we also used the system to do radiant heating under a 500sf tile floor. we had the system set to run through the back of our woodstove in winter when the sun was hiding above the tule fog. we had no conventional heating, A/C or hot water. and we did fine even in the hot summers.

the house was designed for passive cooling too, deep overhangs, the cool water ran through the floor in summer (instead of hot) and with high ceilings and ceiling fans we stayed comfortable.

and this was with technology from the mid 1980s, bet it would work even better today
