Z bracket panel mount question
Using the Renogy Z brackets, how difficult is it to remove the panels should the need arise? Can you get a wrench under the panels to remove the nuts and bolts? Renogy roof mounbts

I searched and could only find 2" x 2" aluminum without any holes.
You can't be serious.
Aluminum angle - all sizes, they will even cut it for you in 6" or 4" long pieces.
I hope you know how to drill holes :)
Use stainless tapping screws and plenty of sealant under the bracket. Regular tapping screws, no split-end like the one shown on Renogy brackets photo. Put sealant in the holes and onto the screw heads as well.
I tried to hit the rafters wherever possible, as 5/8" particle board (nominal 3/4") didn't inspire much confidence with my 250W panels, 40 lbs each. On rafters I used 1.5" screws, or 1" screws where there was no rafter. Go with a 1/16" or smaller drill bit first, to see if you hit the rafter. 1/4" thick aluminum angle 4x4 size (needed it tall to clear the plumbing vents), painted in white Rustoleum. They will outlast my trailer roof.
