Roof mounting solar panel
My new class C from Forest River has a dimpled roof. What's the best way to secure the panels? Some use tape and I don't know if it will stick or should I try screws?

I read reviews about the glued on mounts. I'd be worried about those coming off, especially after wind, UV light, and the elements have weakened the glue after a while. If I were using these to attach panels into a shed, I wouldn't hesitate to use those, however, a RV moving at 60+ miles/hour is a different story.
People also use stick-on panels, but one of the biggest advantages of solar panels on frames, even though they may not have much clearance between them and the roof, there is still a gap, and that gap provides excellent insulation against heat, so it provides "shade" for the rig, no matter where it is parked. Plus, stick-on, flexible panels have a much shorter warranty than the normal flat, framed type.
A big advantage of using framed panels with a gap vs stick on is heat buildup in the panel itself. They lose efficiency pretty dramatically as temperature goes up. A gap behind them gives the ability for some cooling.
