    Again, I said ideally. When will it ever outperform solar on a rooftop of the same size? How much more size could you get for the price?

    It would never overcome its opportunity cost, even if it recovers it’s cost (which you’re speculating on and have no idea of the cost). You could spend the extra money for a solar car, or spend the money for rooftop solar. Rooftop solar will always outperform it for the price, so you have a negative opportunity cost.

      Look at you owning a rooftop to put solar on.

      A lot of americans are renters and that number is unfortunately growing.

        The apartment I was last in was several stories tall and, as such, the parking lot was shaded most of the day. Most of the parking spaces were even in a parking garage, so they get no sunlight. If you’re in an apartment, odds are this won’t work for you either.

        There are companies working on non-permanent balcony solar though, which isn’t as good as rooftop but still something. That’ll still only work for probably about half of apartments (facing east or west), but it’s inexpensive.

        We do need solutions for apartment dwellers, but a solar car probably isn’t it. We need to require a certain amount of availability of electric charging at apartments, and we also need better public transportation options and bike Infrastructure. This is a gimmick solution, not a real solution.
