I made this simple calculation that shows solar panels could never power a car alone:

1 hp = 750 W

The sun puts out 1000 W/m2 in best conditions.
How many m2 do you have on a car? I guesstimate 10, give or take.

So, if you cover the car with 10% efficient panels, you get 0.1*10*1000/750=1.33 hp
If you use 40% efficient space age pannels (the record now), you get 5.32 hp (at best!).

It takes 8 hp to get a car going at 55 mph, a lot more to get to that speed.

Solar pannels can only trickle charge a battery.
