ON-Grid was cheap during the last "great recession". My wife's from "The County".
I appreciate the fact that your current governor reversed the previous governor's scrapping of Net Metering. We've got a 4.6kW array destined for our property in Emera territory. When my wife inquired what Emera wanted to know before we install PV, they basically said: Show us a diagram of how it all works. (I did an NEC compliance diagram for my 4.4kW, the 4.6kW is nearly the same diagram, I can probably handle that). It was like a dream come true when they installed fiber optic internet going past our farm for $60/mo. (Wish I had fiber in the suburbs in South Florida!) I pay more for cable internet with slower speeds in FL...
Honestly, that depends on how far you drive each month. I bought an e-Golf because my commute had gotten so short it was murder on the TDI engine. I'm averaging ~500 miles per month in my e-Golf. That would require 4 south facing 280W PV panels. I've got 4.4kW on the roof (installed in 2013), so I have a baseline knowledge of what my 220W panels will produce. Each of my 220W panels collects enough sunshine to drive 3.25 miles per day. (conservatively speaking, when averaged over an entire year!).
Price them again in a few weeks after the dust starts to settle from the current pandemic. My wife and I went with a Low-E (+argon) setup in our hurricane impact windows back in 2010 when the economy was in the dumps, and eager contractors could be easily found. We also insulated and weather sealed "this old house" which helps more than most people think.
