Solar panels on roof
 
Has anyone who that has put solar panels on there roof regretted doing so?
How would you install them? Semi flexible and glue them? Would it cause the roof to get too hot?

Six panels on the PA for a few years. No problems. Installed with the common aluminum L brackets with stainless screws into the roof. Lay down a pool of Dicor, place the bracket and screw, then Dicor over the screw.

No regrets here. I glued my rigid panels down using L brackets and 5200 adhesive, fiberglass roof.

I used 3M 5200 fast cure and one screw per bracket to keep panel in place till the 5200 cured. Two of my three panels have been on for over five years with no problems. I have a fiberglass roof.

There's been a solar panel on my roof for 15 years. It's bolted to L brackets that are screwed into the roof. Although the panel absorbs heat because it's mostly black, it probably keeps the interior a tad cooler because it's about an inch above the roof and provides shade.

No regrets, just wish I had done it sooner.

I've never met anyone who regretted putting solar on their rig. I've also used the 5200 on my fiberglass roof, and it works well. I recently added another 100w panel using 3M VHB double sided tape with tilt brackets. It's pretty amazing stuff too, 600 miles tested on that so far.

I like using tilt brackets, mainly for cleaning the roof under the panels.

I used the same method as vsheets, but only 3 panels.

When I store for 6 months, I switch off the inverter and lock the doors. Batteries are charged 100% when I get back.

Wow thanks guys. Do you think it would work to 5200 glue the semi flexible panels directly to the rubber/latex roof?

That's the way CC installed the panels on our rig and no problems have developed.

You may be the first to regret putting panels on your roof. :laugh: Just kidding but if you do this and you ever want to remove them or do roof maintenance you may have a problem. I used the 3M VHB on my home made brackets that can tilt and stuck them to my fiberglass roof and they are not going anywhere they shouldn't.

had mine since 99, no regret's at all. wish they had been cheaper back then, would have added more.

This might help: 100 Watt 12 Volt Flexible Mono Solar Panel - ML Solar

"Can be affixed by adhesive, grommets, zip ties or velcro"

You can also use the 3M VHB tape to attach the flexible panels directly without a bracket. Then just use a thin wire to "saw" through the VHB tape if you ever want to remove them.
