OK, half-baked idea here. Have any of you ever heard of adding "water" pipes to the back side of solar cells to soak up and use the heat that is otherwise wasted there. I've touched the solar cells on the top of my motor home on a sunny day before. Those suckers get hot. Seems like you could easily get double duty from your solar panels this way.
Problems? Been there done that?
