Wait wait, how are you calculating that? If you take a generic solar irradiance of 6kWh/day/m^2^ and let’s assume the car has a solar panel area of 3m^2^ with a solar panel efficiency up to 30% and the cosine for solar angle (say ~0.7), given the best 137 Wh/km around, that gives around 30km a day. That’s already enough for my commute.

All this neglects shade, won’t work for all latitudes…but it can also be upgraded with improved battery storage/weight, improved solar panel efficiency and maybe even the area of the car top and shape of panels can be improved (e.g. make them extendable). At worst, you just top it up to 500km from the grid every weekend and that will make up for the difference.
