The math is much simpler than you think, I just take the difference in cost between filling my tank with gas and charging the Bolt's 60 Kw battery extrapolated for one year. This come to roughly $1000 a year and voila you get a ROI of 2-3 years.
Ah, so you do compare to gas rather than electricity. I could go into why I believe this is wrong/misleading, but that's just my opinion. In a nutshell, without the solar panels, the Bolt will still cost less to charge than filling your tank with gas. The benefit of going from gas to electricity is essentially being counted twice.
What matters is that you are happy with your purchase. It will save you money for sure.
