I am thinking that this is mostly marketing. Plus, installing PV on a car is not new. Half the top tier engineering department in the US have a setup for that, some are nearly 20 years old. But PV have come down in price, they’re still not very efficient, and the benefit will be marginal. I’d rather install PV on every parking lot instead, that way it is always connected to the grid. Unlike the car which is only connected when plugged in.
