Took me two days of grinding and repainting the roof.
3m vhb solar panel mounting.
My flexible panels failed both so i had to get that tape of.
Hey everyone we had been thinking about solar panels since day one of our full time casita experience but we did not want to have to drill through our little eggs fiberglass shell and didnt want to spend too much to have it installed professionally.
Am solar told me that they use 3m vhb not sure which part for many years on many rigs and have never had a failure.
With a helper remove the red backing from the vhb tape and turn the solar panel over.
I ve had the gray vhb tape with red liner on my solar panels for 4 years.
The final step is sticking the solar panel to the roof.
Evenly and slowly lower the solar panel and stick it to the roof.
Really really hard to get removed.
When you prep really well that stuff sticks.

I emailed the owners to ask about this and quickly received a very nice and thorough reply.
Cut each 5 strip in half for each of four mounting feet per panel.
For a sample size of one i used it on my 06 aspect with 2 100 watt panels and drove for thousands of miles in high winds from the front and side probably over 100mph combined at times in nevada with no failure.
Am solar sells a solar panel mounting kit that optionally comes with 3m vhb tape instead of screws.
We do a follow up on how my solar panels held up over the past 5000 miles through hot and cold weather then review the viability and applications for double.
3m vhb tape is used to secure mounting feet and combiner boxes to fiberglass or metal roofs not rubber.
Basically they ve been using this extremely sticky tape for over ten years with no reports of panels coming off including 6 panels on their own rv.
