Solar panel mounting options on 310rl

[patrickmn99]

Hope someone can advise me on securing panels to roof. I will install unistrut from front to back and only securing on the Rafters indicated on roof membrane .I do not believe there is any good material between rafters to use any sort of lag screw ????

Hopefully, someone from Alliance will answer this in a timely manner. I have two Renogy 320W panels due to be delivered any day that I am adding to the one already on my roof. I think I saw in a plant walk-thru video where they were putting sheets of plywood on the roof between the rafters and roof membrane. Fingers crossed.

Curious if you are using the Renogy 60amp charge controller MPPT for all three panels.

I mounted an additional 3 320w Renogy panels with Self Tapping Wood Screws and Afcat 945 Sealant below and above the brackets. This was the method taught to us at the NRVTA Solar Class, and so far, everything is holding well after about 2500 miles.
