I would not trust adhesive on the backs of panels for decades. This would be especially a concern with tiltups or ground mounts where there is more wind loading.
When mounting some frameless BP modules I made some 4-inch long edge moldings of slotted hard foam called SeaFoam that is sold (but not manufactured) by Tap Plastics.
Then they were compatible with standard bolt-down edge- and mid-clamps.

wrenches,
i have a customer who purchased 20 used astropower ap75 modules. they are frameless and appear to have been previously mounted using four, 2" wide X 10" long strips of blue rigid foam, glued to the back of each module with some kind of adhesive.
two questions:
this seems to be a reasonable mounting system id like to repeat. would anyone familiar with this kind of mounting technique be willing to comment/speculate on an adhesive that would not degrade the tedlar backsheet? whatever was previously used worked great.
what kind of flat/smooth mounting surface would folks suggest the other side of the blue foam be attached to? the only thing i can think of is plywood, but that would rot over time.
thanks,
todd
