Not to hijack my own thread but was scanning through some RV solar panel mounting projects and notice how much difference there was in the distance between the panels and the roof of the RV. In my case I used Renogy two piece mounting brackets and was limited on the height of the panel.

My roof is curved, the ends of the panels are 3" from the roof the center of the panel is 2 1/2" from the roof.

I read that to allow fro proper panel cooling 3" minimum but 4" to 6" would be ideal.

I was wondering what the consensus would be on panel height?

I'm far from an expert, but... I think most Z-brackets only provide about 1 inch of spacing between the panel and the roof. I'm guessing it is fine. If you've got 2" or 2.5" that seems like more than enough.

I used two aluminum rails and four L-brackets to mount each of my panels.

Mine have maybe 2" underneath and none of the three RV's they've been installed on have caught fire yet...



  • 2019 Grand Design 29TBS (had a Winnebago and 3x Jayco owner)
  • 2016 F-150 3.5L MaxTow (had Ram 2500 CTD, Dodge Durango)
  • 130W solar and 2005 Honda EU2000i twins that just won't quit
