How much power from a solar panel on every vehicle?

This particular product is an aftermarket device that provides 250 watts in full sun. It only powers the car for “20 miles” if you let it charge for the appropriate amount of time (hours upon hours, or more in anything less than full sun).

and it doesn’t take into account the cost of modifying the Prius so that the output of this panel can actually charge the traction battery.
