[quote=threadkiller]I think the problem with leasing is that you are not rewarded for cutting down on usage, I could be wrong. Just noticed that Costco is selling a 5KW system for $17,000 of course you still have to pay someone to install it unless one is licensed by the state in order to get the rebates I think.[/quote]

if you buy power for 11 cents, it’s a 10 year payback, if you buy at more,
it could be a 2 year payback.

5KW system, x12 x 365, is about 20,000 KWH.

in many places peak power is rising rapidly in costs.
