I'm looking to build a very large custom roof hatch/vent on my van. I was going to make to top out of Lexan, but then I realized I might want a large solar panel on the roof as well. I was looking at the aluminum structure of solar panels and read the edges are water tight. Any reason I can't use the solar panel itself as my hatch top? Structurally I think it will work, and I know panels get hot just like my metal roof gets hot, but wonder if there are any chemical reactions or gases that will enter the van as a result of the back side of the solar panel working. I also know solar panels need ventilation underneath, but then again, so does my van inside during a hot day.


You probably could do this and by biggest concern would be the solar panel breaking from opening and closing the hatch
