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.<br>
<br>
two questions:<br>
<br>
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.<br>
<br>
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.<br>
<br>
thanks,<br>
