By far most, I’d say. And actually I’d say that parking garages and residential garages are both natural places for plug in charging. It’s street parking or vast (unlit) outdoor parking lots that would be a challenge for plug in charging, exactly the places that would work fairly well for solar car charging. So I think it’s a valid niche. The issue is it’s still annoyingly expensive to place solar cells on car surfaces, and really we should use those high efficiency multijunction cells. Tandem perovskite cells are very promising there, getting both high efficiency (over 30% and rising) and low cost. But conforming shapes to car bodies is also a challenge. However if those can be solved, it’d be great to have this option.
