Locations in San Diego average 5-6 solar hours per day. Your numbers seem high/overly optimistic. Either way, I am very intrigued at this point.
BTW. I believe that if you feel like you can pull off A DIY job you can probably find someone to help with the permitting and whatever rebates plus some oversight if needed at some fair price. Not recommending it necessarily. Seems right to me that if the system doesn’t work because of BS, you make it work when you can.
I think, maybe hope or guess,that solar is now on the right track with cost benefit though. I think it’s worth doing taking the reasonable assumption that electrical charges (no pun intended) are going to go up.[/quote]
