I'm shopping for a 1st RV and was looking at a '04 Newmar (so has the Britec roof). The person selling it lived it in F-T since new (his 2nd Newmar, ordered new, and is in a (new?) 40' Dutch Star DP)) and installed 8 solar panels on the roof + a 3000W inverter (and 8 coach batteries in all he's a retired electrician). Just wondering how should the panel mounts be mounted? The roof was mostly covered in snow so I couldn't see.

Thanks in advance

Mounts should keep the panels about 2 or more inches above the roof.

Depends on how they mounted them screws or tape. I chose screws with decor , as said about 2-3" off the roof. No leaks no issues 5 Years now.

Thanks again. The panels were lifted off above the roof with the recommended spacing. I will have a closer look if the owner is amenable to negotiation given condition inside.

Went to look at the RV again today. 6 big panels and 2 smaller ones. Unfortunately roof by the rear cap was soft and pillowy, which is not what one wants to see.

Unless they are flexible panels which are typically flat secured to the roof. ByeTheWay is correct for residential panels. Just wanted to mention the other way.

I used 6 inch long 4" x4" aluminum angle to mount the solar panels. Glued down with 5200 marine adhesive sealant and 2 short screws on each of my 66 x 39" panels. Used rivnuts in the solar frame and attached with 1/4-20 screws.
No issues
