mounting solar panels ??

How is everyone mounting there solar panels on a fiberglass roof (Seneca) ?

I've read some people are using 3M VHB tape with no holes drilled.

Any thoughts on the no drill method ?
I'd hate to have a panel fly off the top at freeway speed.

Seems simple screws and some sealant would be the route to go but figured I'd ask before I dive into this project.

Do not only use vhb tape if your roof is textured like or Alante is. You are gambling against the odds of you do. If the Seneca only has thin plywood (1/8-1/4") under the fiberglass - email Jayco Customer Service to find out - you will need anchors like what we used: https://mansiontools.com/ez-ancor-st...hoCFKAQAvD_BwE

Here is a thread I started explaining how I used rubber grommets to attach the panels. I have an EPDM membrane roof but these would work on fibreglass.

I used flat flexible panels and taped them down with eternabond tape. no issues so far with over 2000 miles on it. Still look like the day I installed them.

Do you have any pictures of how you taped them down ?
Just wondering where and how the tape goes...

I put it around all four sides of each panel and used it to secure the zip tie mounts
I will be adding 2 more panels. tried to space them out best I could to avoid shading from other items on the roof. So far even with the four panels I am getting great power, even on cloudy days. 2 additional panels should help with any shading and with sun angles throughout the day.

Cheers
