My plan is to use flexible panels due to their inherent light weight, but still attach them slightly up off the roof's surface to keep heat build-up in the panel to a minimum.
Here's how:
- Use aluminum or stainless steel brackets that I glue onto the roof's fiberglass surface using 3M's super strong double backed tape (the same material that they use to glue windows onto high rise buildings).
- Stretch tight and screw (using stainless steel screws) onto the brackets a metal mesh (made of aluminum or stainless steel).
- Screw the flexible solar panel down to this metal mesh (using stainless steel screws/washers spaced about 10" apart all over) - being of course very careful to only put the screws through areas in the solar panel material where there are no circuit components.
This approach will keep an air space under the panel for cooling and keep the whole assembly light weight and with a low wind profile for minimum wind stress on the double-backed tape while going down the road and in high winds when camping.
Maybe a crazy idea to keep from putting holes in our roof while at the same time keeping overall solar panel assembly weight and wind resistance very low??
