I have purchased a Renogy 160W flexible solar panel that I intend to mount on the roof of my 1985 16 footer. I have been debating about attaching it with an adhesive. Renogy suggested possibly using some stuff called Sikaflex 252. I've seen some youtube videos of it done with Dicor and or butyl tape and eternabond. Using an adhesive is probably the best method. But I'm also wondering about attaching it with some bolts through the gromets on the panel. This way I could theoretically remove the panel and move it if I'm camped in the shade. I'm a bit reluctant to drill a bunch of holes in my roof. Doing that would probably be the secure way to attach some bolts. But I was also curious if anyone has ever figured out a way to attach a bolt to the exterior of a fiberglass roof in some way so that it wouldn't just tear off while driving down the road. I'm curious if anyone has tried any alternate ways of attaching a flexible panel and if it worked or if anyone has any suggestions.
