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
In my business I see quite a few broken modules each year. As I recall, in
every instance there is a visible point where the impact occurred. Typically a
small radial pattern is around the impact point but then random patterns over
the rest on the module. Look close. Hope this helps.

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
A few years ago there was a rash of this type module glass breakage caused
by flaws in the glass, that would not show up until a year's worth of
thermal cycling. I saw several of the non-frame glass only modules fail in
California sun. Without a frame they would curl-up into a U shape.
