Yeah I've got family that are like this. I'm kinda wondering what you'd actually need for solar to change a vehicle for say a drive to work and back in a mid sized city (10-30km) on the average electric vehicle.
One the the reasons I haven't gone solar here is not so much cloud as cloud+half the year the things are gonna be covered in snow+smoke during the summer (we actually have issues with solar-powered parking kiosks already due to this).
If I won the jackpot though I'd definitely go "prepper" with one item being a solar-powered retreat I'm a location that gets a decent amount of sun without too much dangerous weather.
