Interesting, but here in SCE territory on-peak is from 10-6, not 3-7, so I expect keeping my panels facing south will remain the best move (not that I really had a choice with my simple install - my roof faces south so the panels do too.) The recent time change does move the on-peak period 1 hour later (relative to sunlight), though. If only I could adjust the orientation seasonally! :lol:snoltor said:
