broken modules [RE-wrenches]

[Todd Cory, Mt. Shasta Energy Services]

Wrenches, I need some assistance with a peculiar problem that happened 
to a system I installed this last fall. It is a roof mount at the bottom 
of a ~5/12 comp roof. What happened is evidently the snow/ice caught on 
the lower edge of the module frames (where the glass meets the aluminum) 
and believe it or not, peeled the frame right off the bottom of one of 
the modules, which left unsupported glass which then broke. The other 
two modules on this three module system had the bottom edge bent out, 
and no glass breakage but I do not know how to bend that back again so 
they may be a lost cause. The modules were mounted in portrait mode so 
the short side was subjected to this and granted, we had the snowiest 
January in 40 years, but I just did not expect to see this happen.

Has anyone else seen this kind of damage occur before, and can you 
suggest a solution to prevent a repeat performance? I was thinking about 
two possible solutions. One is adding a piece of angle iron across the 
bottoms of the three modules bolted to the edges of the modules frames 
to better support the centers. The other idea was to change the mount to 
a adjustable angle roof mount... set very steep for the winter with the 
thought that if I can get the snow to slide rather than creep this might 
do the trick, but I am not sure. This is the first time I have seen this 
happen.

Thanks for the help from the other folks that work with the harsh 
conditions in heavy snow country (and you coastal wrenches thought 
corrosion was a problem)!

Todd
