Bill is right about concentrating solar, there is no magic gift doing it. I test solar thermal collectors in my professional capacity. I recently tested a concentrating system that made 400F temperatures in the heat transfer medium.
Do you really want a concentrating system? If you put 3000W into one meter on the roof of a car that is what you will get (a 1 meter collector, with two meters of reflectors around it). There are a number of other contrary details beyond this show stopper. Much more practical to fold out a bunch more PV.
