Flexible Solar Panels on Side of Truck Camper

personaly I think it would be a lot of money for very little pay back.  sitting at 90 degrees would be very inefficient unless your in the desert and are facing the sunrise, and then it is weeker so you won't get full power but you'll get a boost.  but that would be gone before noon for the restof the day and before the sun is at its best solar output.  now if like the last post they were on "awnings" you could flip up horazontal then it might be worth it, but you could use regular panels with a higher efficiency if you were going to do that.
