In armageddon, you would run out of fuel around day 3 and then that's it.

A CyberTruck will charge just fine from anything that can generate the proper AC or DC, no phoning home needed. Many home solar installations can work off grid and charge your car.

To charge a 57,000 watt tesla with an 800w consumer solar panel would take 71 hours of sunlight. There is not 24 hours of sunlight in a single day. This also is not considering the battery management which heats the battery passively. So it would take a week to charge a Tesla with equipment that you could carry inside the car.

Strange that you assume a single solar panel? If you’re installing solar at home, wouldn’t you install more than one panel?

I have a 15KW setup at home (kinda large, but adjust the numbers to what’s reasonable for you), it should charge the Tesla in less than 4 hours.
