I have done solar laminates.
Do it yourself alternative energy
I definitely would make provisions to allow air to cool the back of the panels unless you live in a very cold place. I bought the junction boxes, laminates and made my own frames from super strut material. I mounted two per frame. That seemed to work best because of the weight. You still have to pick them up and mount them somewhere. Also, I had baseball sized hail a year or so ago. One double panel was broken beyond repair and had to be replaced. It wasn't too difficult because only 2 panels were mounted together.
If you want to start from the solar cells themselves look here:
Making decent solar panels series
About 3 months ago, I bought UL listed panels ready to install for the same price I paid for all the materials to assemble them. Laminates alone, as I understand it, cannot be UL listed because they are incomplete.
