I am intrigued by the idea of using solar panels in my Airstream. This is on my must-have list, but will have to wait until after the interior gets remodeled.
I recently had the opportunity to do some bid work in the Toledo, Ohio area and found out about a great little company up there making flexible solar panels. (One could potentially drape the panels over the top of the camper and down the walls a bit, for a nice flush look.) The company was founded on research done at the University of Toledo. The company is called Xunlight.
I don't know if anybody has tried these panels or not, and don't know if they would work in an RV application. However, I did get to work with some of the people at the company. It was a great experience, and very friendly folks.
If anybody is interested, ask for Jim Young.
I'd like to know more about these products if anybody has had experience, or is willing to try it out.
