45 yo. The house I'm putting solar on is in northern California (far enough north to not be part of SF Bay Area). PG&E has my TOU rates at 0.36/kWh off-peak, $0.38/kWh peak. And because it's fire country and they took a 30 year break from maintaining their lines, they can shutoff power on any windy day during the summer (my parents had 5 or 6 days without power not too far from me a year or two ago).
I have a 20 kWh battery Nissan Leaf EV that I'll probably upgrade to a better make with longer range within a couple years.
So, if I lived there full time, payback at ~$0.37/ kWh would be pretty fast, maybe 3 or 4 years after subtracting the 26% (or 30%?) tax credit. Until I can retire (hopefully 5 or 6 years if things go well), I'll only be able to be there 1/4 to 1/3 time.. so probably 6 to 7 years or so to break even.
However, my inverters will have excess solar input capacity beyond what I need. I may add some free / cheap used panels in addition to the new panels I'll buy. If so, with plenty of excess production, I may invite my parents and my neighbors to charge during daylight if they buy an EV. That'll either be a gift or a trade or maybe just honor system at 10 to 15 cents per kWh, but either way, it can push the return of value on my system back down to 3 or 4 years. It just won't necessarily just be me gaining from my system
Note that I'm aiming to be off-grid, potentially with grid only as a backup to charge the batteries at night or after a string of cloudy days
