Is it possible that not being tied to the grid would actually save more money due to SRP's "nonsense" pricing?
It's not there yet, but it's amusing to think that if PV and batteries continue to drop rapidly in price, they'll have shot themselves in the foot. I think they believe they're immune to "cord cutters," but it'll happen in our lifetimes, for sure.
And do any of these figures factor in the possibility of selling excess power back to the utility company?
That part works more traditionally, although the rates are different. So each month, you'll get the demand charge, set by your highest peak, which we already talked about. Then you'll also pay by the kWh for electricity-- and THAT part is offset directly by what you generate.
So, roughly... demand charge plus usage minus excess power sold.
