Solar Panels on the Roof of a Car

The vehicle you raced across australia in had a flat roof that's not hapeople want in the family cars. So one of the key things we had to solve, of course, was this flat roof - as you mention. And the reason we had it was actually for a efficiency. Just from the curvature, you lose 25 % of your solar energy if you put all the cells in one chain. But what we could do was break the one big chain up into a lot of small chans and that way get e efficiency back. All this pretty remarkable.
