Am solar have been doing it for a long time and reported to never have lost a panel.
3m vhb solar panel.
The electrical system of our campervan is designed to power our appliances fan lights 12v fridge etc and can be charged with solar power alternator or shore.
Cut each 5 strip in half for each of four mounting feet per panel.
At first look you think this is just double sided tape but it is really so much more.
It is commonly used for building cladding and other architectural applications.
A screw will grip through the sheet metal the tape rely solely on the paint to hold.
A continuous perimeter of vhb if properly applied will securely bond and and create a waterproof seal between the solar panel and enclosure.
3m vhb tape is used to secure mounting feet and combiner boxes to fiberglass or metal roofs not rubber.
It s understandable that many people are leery of drilling into the roof of their vehicle to anchor their solar panels.
If you say freedom we say solar power.
Therefore we don t recommend to use tape on rusted damaged or used paint.
Improperly sealed holes in the roof can be disastrous allowing water to penetrate and destroy insulation upholstery and sheet metal.
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.
It is amazing how many times we suggest 3m vhb as a method to attach a small solar panel to an enclosure.
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.
These high strength tapes are ideal for a variety of solar bonding applications including frame bonding and junction box bonding.

We took to the forums looking for ideas and ended up creating a little.
It is a gray 0 062 in.
1 6 mm multi purpose acrylic adhesive with a conformable foam core and film liner.
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.

In other words we trust the tape method because the van is new.
We selected 3m vhb tape to avoid drilling through the roof.
