Solar panels are literally plug-and-play, though! If your market doesn't have plug-in "balcony solar" yet, it is because your lawmakers are blocking it.

And indeed, they can tax excess solar, but they can't tax the power you use yourself. Backfeed tax gets too high to use the grid as a battery? Buy a home battery, problem solved.

Plenty of grids have different sorts of net metering ratios, grid maintenance fees, etc. But it's nothing compared to what you'd be paying taking power off of the grid, and there is a break-even period often measured in single-digit years. I still do not understand the point of what the GP was trying to make w.r.t. "taxes".

Strange, I lived in very blue states (WA and CA) and they definitely punish EV owners with large annual surcharges on registrations. To offset “not paying gas tax”. Money is money, red or blue, they will all take as much as they can from you.
