Question s regarding mounting panels on a curved roof?

I go for all cells in a string having the same sun alignment. Otherwise, those with the
worst alignment will hold back output of the others. Bruce Roe

You could fabricate some wooden trusses by making a template and duplicating them out of 2X lumber. You asked.

Anyone else have any thoughts?

No expert but have seen many boats in the local port with large panels apparently glued to curved deck surfaces, in fact have seen people walking on them with slippers?

Saves any mounting frames ect.

I have seen that with flexible panels. Mine are conventional flat panels in aluminum frames.

The downside to gluing down flexible panels is that there is no air flow on the back of the panel.

Thanks for the suggestion.

Hello Everyone,

I am considering mounting methods for a bus solar project. The curved roof creates some challenges.

Initially I was going to build a flat deck elevated 3-6" above the roof and attach the panels to the deck. Unfortunately, the materials cost is looking like it may hurt the budget a bit.

I did some searching and found this: http://www.skoolie.net/forums/attach...3&d=1467607040

In post #3 he shows mounting two lengths of Unistrut to the roof then the panels to the Unistrut.

My questions are: .

Is this method strong enough to secure the panels adequately?

Will the panels be too close to the roof to allow adequate air flow?


Before any, well intentioned, discussion about tilting panels starts.... I have made the decision to mount them flat and "over-panel" a bit.

What do you think?

Any suggestions?

Thanks
