This is really not going to be charging your battery much. You can barely justify the energy usage in creating the panels. Useless if you park in a garage at home or at the office, or have a tree overhanging the car. The panels themselves have a shelf life too. I would personally prefer it if you were able to fold out panels (or for extra points, the panels fold out themselves). I think you could quite realistically have a large "sun roof" that folds out panels instead - then you would begin to get some better power returns. Add to that some sun tracking and you can massively improve your efficiency. But really, just give owners of the car something to install on their garage roof and a plug for the car.
