If you don't see any sign of impact, look closely at the area in front
of the junction box. Any discoloration is an indication that it has been
hot in that area. This often is the case with a shorted diode. The heat
will stress the glass and cause it to fracture or make it susceptible to
fracture from any minor stress. The glass will usually have larger
fragments in that area and finer fragments farther away.
A shorted diode should be warranty issue.

Wrenches,
I recently inspected a system I installed in 2010, because the owner
commented that it appeared the frost wasn't melting off of one
particular module as it was from the others. Turns out the module
glass is shattered. There are no obvious (that i can see) impact
points, leading to the question... Why did the glass shatter?
I don't want to just assume, but if there is no sign of impact, I'm
wondering if this could be a warranty issue? Frame
expansion/contraction due to temperature swing maybe?
Any experiences, thoughts or advice?
Module is a Sanyo HIT N215A01
Thanks,
