Display for PWM Controller?
After years of thinking about it, I’m about to get a solar setup. I live 5 minutes from SolarBlvd in Norco, so I will get most the stuff from them. The plan is to use the 140w Solar Cynergy panel (...

OK, what do I look for in mounts for a fiberglass RV roof?
Check the list of completed solar projects here at the forum.
It's not just the roof material, it's the brackets shape. What you need is an L-shaped bracket, like a piece of 2x2 aluminum angle. You bolt it to the rivet nut in panel side. OTH, with Z-bracket you attach it to panel bottom first and then to the roof, and to remove the panel you have to rip the bracket foot off the roof - not a good idea.
The foot of the L is attached to the roof and this is where roof material matters. If flat fiberglass, some people took chances with VHB double-sided tape. If crowned - well nut is the way to go, and it would work on a flat roof too. Some drove tapping screws in, because there were metal braces underneath. With well nuts you have to make sure not to hit the braces of course.
