That's tricky though. Would you deplete it during night to have it empty in the morning? Wear expensive battery? Plus, I assume, car is disconnected from grid for most of the day (i.e. when you are at work).
But you park it at work there could be slow AC charger, to slowly charge it when you are away.
Placing solar on rooftop of car also seem as good idea
"solar-powered cars" have been tried many times because it's a great headline, but the math never works. Cars simply don't have enough surface area to capture a lot of solar power. The amount of energy is low enough to not be worthwhile, except in the most extreme edge cases.
You don't have to charge 100% using solar
