Zoom in on any satellite shot of a city, or a road... count the cars vs the solar panels you see. Yes cars are out in the sun... lots of them, all the time. The fact the satellite can see it means there is solar energy in that spot, right when that photo was taken. Multiply that by "All the cars outside in the world" and it's a lot of energy. (Even if they are all still plugging in at their destinations as well).
