I love the idea of solar panels, and being fully independent without reliance on government systems. Not to mention, the sun hitting your roof is energy you don't even want. Why not convert that back into electricity?
But that price tag is brutal. I assume to solar panel your roof would be around $20k+. Plus the price of an EV. These aren't items you can really buy used either. Old/weak EV batteries aren't "repairable" like an old car is.
It just comes back to my point of it being a nice luxury for rich people. I keep my budget for my vehicles at $5k max. I will never see a new/used EV & solar panel system for that price.
