3M Dual Lock is like Velcro, except with plastic mushrooms. So the solar panel can be easily separated from the fiberglass top, and put back into place (multiple times).
The adhesive for each side is the same type of adhesive used for the different 3M VHB dual-sided tapes. That adhesive may be tough to remove.
There are many different versions of 3M Dual Lock. So you have to choose the right one (differences in number of plastic mushrooms on each side, type of adhesive, etc.).
The typical 3M Dual Lock is about 1/4 inch thick when both sides are pushed together. That creates an air gap where the 3M Dual Lock is, as well as a bit of leeway in depth.
There are also low-profile 3M Dual Lock versions which are about 1/8" thick or less.
For flexible solar panels using 3M Dual Lock, installers suggest that additional spacers or support be used in the middle of the solar panel to account for the 1/4" thick 3M Dual Lock on the perimeter. The suggested spacing is no less than 8" and in some cases, between each row of solar cells.
Spacers can be additional 3M Dual Lock (installed on one side or both sides) or strips of twin-wall polycarbonate.
