Re: [RE-wrenches] used panel mount questions
Don Actually Very High Bond (VHB) foam tapes are incredibly strong and if formulated for glass, will work quite well. They have been using it for decades to mount heavy glass and aluminum panels on curtain walls on sky scrapers. I would trust it totally as long as it was not bought at HomeDepot. I have tested it with heavy loads and the aluminum frame failed before the tape and glass module!

Re: [RE-wrenches] used panel mount questions
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.

I've seen rack "edge clamps" for frameless PV advertised, but didn't make a mental note of made by whom, or where I saw the ad. I *do* recall the clamps were intended to be located along the long edges, not the ends. Otherwise, expansion/contraction would stress/break the glass.

Re: [RE-wrenches] used panel mount questions
I agree with Allen, and would like to add a related comment. Foam boards are thermally insulative in nature. If affixed to the PV with adhesive, they would cause the PV module to run hotter than if the backsheet was fully exposed to the air. This results in reduced energy output under all conditions, and increased thermal stresses on the PV cells, internal buss, bonds, and other aspects of the PV.

Re: [RE-wrenches] used panel mount questions
Hi Allan and Todd. these modules sound like the ones that Powerlight used back many years ago. These modules were mounted flat with the blue foam as insulation/mounting. the concept while pretty cool at first look didn't work out. Not sure what to tell you about what/how to mount them too however. jay peltz power On May 30, 2013, at 3:46 PM, Allan Sindelar wrote: > Todd, > I don't have your answers, only the caution that "blue foam" to many of us > with a construction background means extruded polystyrene or "blueboard", > commonly used around foundations.

Re: [RE-wrenches] used panel mount questions
Todd, I don't have your answers, only the caution that "blue foam" to many of us with a construction background means extruded polystyrene or "blueboard", commonly used around foundations. It deteriorates with exposure to sunlight, so could only be used in an application such as this if protected from UV.

[RE-wrenches] used panel mount questions
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 ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
