I have used VHB to attach awning rail to the trailer. The tape only holds the rail until you camp and insert the awnings. The rails were sealed along the edges with Proflex to prevent the VHB from drying out. Stored outside and 30,000 miles so far and awning rails are still firmly attached.

AM Solar says they use the tape, I'm assuming it is VHB tape or similar to attach the solar panel feet and do not drill through. They then show coating it with Dicor. According to them they have never had a panel blow off since they started. From their site:

"Fiberglass roofs – We have been using a type of 3M double-sided tape on our mounts since the mid 1990’s, and we have never lost a panel. As long as the tape is properly installed on a clean surface at the correct temperature, it will hold. As an added level of protection, we use a layer of Dicor self-leveling sealant around the entire perimeter of the mount, and cover the screw holes/heads as well. The sealant protects the tape and any potential roof penetrations from water intrusion and decay."

I'm glad you're getting so much use out of your 15b. I'm also glad you sealed the VHB tape with Proflex (and believe it or not, so are the drivers that follow you on the highway). But realistically, the tape couldn't care less about the miles you've traveled since the installation, it's the amount of time that has passed.

I'm reading that AM Solar uses Dicor sealant to 'cover the screw holes/heads as well'. as well as any potential roof penetrations. So... does AM Solar use screws, a type of 3M double-sided tape and sealant? Sounds like it.

Ahh... But I believe trips to 110 degree areas and the flexing of the body are indicated by mileage. My window mastic wouldn't continue to exude if it just sat in the driveway. The mileage was included to indicate that the trailer and the adhesive has been under stress and many different temperature extremes which 3M does indicate is a factor in longevity.

You could be right. I guess you'll see won't you.

Am solar Installation

I just returned last night from picking up my Escape in Chilliwack and stopping by AM solar on my way home to have them install my solar panels, charge controller and monitor.

Yes, they use 3m tape sealed with dicore or Sikaflex in my case. They screw panel mounts down when there is a plywood base to attach and seal . It was determined that screws into the Escape roof would not add strength so no screws were used on mine and the stronger bond of sikaflex was added over the entire foot.
They claim No failures to date, but most of there panels have installed on RV's that allow for use of screws into plywood. They could not tell me how exactly how many similar installs they have performed but estimated over 1000 and 4 Escapes in recent history. As stated earlier proper temp cure and sealing is absolutely necessary, water infiltrating the 3M tape will cause failure.

The panels were mounted low to help reduce wind loading and I will fabricate a front " wind deflector" and " side skirts" and attach with the same 3m tape and sikaflex to maybe help in seeing degradation of the tape and sikaflex.

Overall AM solar is really confident in this approach. By keeping wind from getting under the panels and regular inspections I'm hopeful this is sufficient.

I'm glad to learn the proper way to install a solar panel using 'double back tape' is to also use a Sikaflex or similar bonding material to completely cover the entire mounting legs. My guess would be that the double back tape keeps the legs in place while the Sikaflex or similar is being applied. The first solar panels installed by Escape, if my memory is correct, was with double back tape only. The photos provided by craiginpetaluma have cleared that up.

Congrats on your new 21 Craig. It looks like you got their Tilt Mounts on the panels??

Craig,
Is it possible you can post picture of the new style control panel ETI is installing now? Thanks
