And that has precisely squat to do with my intrigue into looking at a system like this. If it didn't make sense, I wouldn't be interested. So what's your point exactly?
It may or may not make sense depending on your location. Many utilities would prefer to make customer-owned solar a very poor financial choice thru rate design (e.g. very high minimum charges, per-kw-installed solar charges, low daytime rates relative to evening rates, wholesale-rate compensation for exported production, etc). Some succeed.
