Finally The camper is wired, the batteries are installed, charge controller is all set; so it is time to mount the solar panels.
I am mounting two 100W Renogy panels, spaced 1" above the roof, with 2" x 3" x 2"wide 'L' brackets, 4 per panel.
The panels fit across the roof and the roof frame is 1" aluminum square tubing, going front to back.
My questions are:
1- Will four #10 sheet metal screws plus 3M 5200 adhesive be enough to hold a panel to the roof? My roof is corrugated aluminum, so I only have ~1.25" wide flat spot for adhesive. I could easily add a second fastener on the 3" leg, but anything more and I will have to go to a different mounting solution.
2- Is it advisable to slightly tilt the panels to the front? If so, how much? I have read claims that tilting slightly helps rain clean the panels. It also insures that air flow doesn't get under the panel to lift it while driving. Panels are to be rigidly mounted, not adjustable.
Thanks for your help. -- Spiff
