Sorry we got a 4kw and 1PW system, total cost was $20,200. In APS you would benefit more from a larger PV system vs having the PW. The reason I got the PW was too eliminate any demand charges from SRP and to get the $3600 rebate.
We're almost on board with the Powerwalls, but the cost on those is just so high. I'd not heard of that Powerwall rebate--is it ONLY for SRP customers, or can APS folks get it too?
I believe it is only for SRP customers. If I was in APS area I would go for as big of a system as I could afford and forgoe the PW unless there is a demand charge
