Peel and stick Solar panels

[Enigma]

Anyone have any experience with these peel and stick solar panels? They seem relatively inexpensive when compared to the rigid aluminium framed ones.
Only trouble I'm having so far is trying to find one that is short enough to fit along the roof of my 80.

I've seen some threads (not here) where their owners really like them. Since current chemistry solar panels work best when their backside is cool to cold I wonder if the stick-on panels get enough cooling to be their most efficient.
