Even if you did the work yourself it seems like it’d be impossible today to get panels, wiring, and much of a battery for only $10k.
How do you get 10 year payback saving only $1400/year?
If that $10k could be stuck in a Roth it seems like it’d be crazy if the decision was strictly financial.
If you live in California where the grid is sketchy I could see wanting to have it just for redundancy.
For a utility there is no ROI.
