Mounting Solar Panels to Unistruts/Rails?
I plan to install solar on my 2016 Class A rig later this summer and I was wondering if anyone has mounted their solar panels on unistruts/rails? It seems to me that I could get away with fewer screw-down points on the roof if I used unistruts and it would give me more flexibility if I had to change out a panel or if I wanted to add tilting brackets in the future. Whatever the solution, I would configure it so there was about 2” of airflow gap below the panels to help keep them cool.
So, what is your opinion on the use of struts/rails vs bolting the panel brackets directly to the roof?
Check out the AM solar website, they have excellent how to videos. Jon
Some folks use rails to raise the panels up over vents as well as get them above the raised sides. Some larger class A coaches have the awnings built into the roof line with raised sides on both sides.
Mounting solar panels to a rail system allows more panels and reduces shadows.
However, mounting solar panels to raised rails can greatly increase the cost of a system and I'm not sure it would reduce screw points.
I used aluminum Z brackets duplicating the factory mounted panel that came on our coach. A set of Z brackets was only $10.
