SoloPower SP1 thin-film panels

I have 8 SoloPower SP-1 thin film CIGS panels. These are not the cheep flexible type you see on Amazon and eBay. They are 80 watts at 24v so they are perfect for a RV of some kind. I have extra ones from a project and they are just sitting around.

I would be happy to sell them for $80 ea.

The picture is broken, how do they mount?
