[RE-wrenches] module frame separation

[William Korthof]

Recently we've had a few modules (~5 year old) exhibit frame  
separation from the glass...
in one case, it's minor separation of the long edge of frame on one or  
both sides of a few modules... the frames seem okay and reasonably  
secure when attached on the roof, but were loose during handling.
In another case, the customer is located in snow-impacted mountains.  
Apparently, a sheet of icy snow pulled the bottom (short) edge of the  
frame apart from the glass and side frame pieces. No damage to the  
glass, but the lower edges of 6+ frames are now dangling by a thread.

I don't think the module warranties cover this problem---the power  
output remains within spec and there is no evident damage to the  
glass. But if we don't provide some sort of repair, the modules will  
break.

Any suggestions for this kind of repair?
What kind of glue would we use to reattach the glass to the aluminum  
frames?

Thanks,
