I made my own solar suitcase panels (check out the solar suitcase at renogy.com) I used the flexible panels over an aluminum frame I constructed from stock at HD. 200W is more than enough for us and it folds to 23"X17" and weighs 6 pounds. Easy to move, easy to store, needs an anchor of very windy days. I can put it on top when we are out of camp if I'm concerned about theft, or just restore it under the camper. Sun moves, it moves, easy to expand if we ever want to and easy, easy on the back. Oh and there's no glass to break or crack.
