The bottom corner modules are the likeliest to be damaged by somebody or
something moving past the array. I'd check for any damage on the edge of
the frame. I had kids run a vehicle into a pole mounted array once. No
one would cop to it, but I found the matching damage on the roll cage of

Dave,
I have worked with many DP&W pole-top racks, as it is our
rack of choice for battery-based (mostly off grid) and water
pumping applications. While I have seen errors in construction,
they have not tended to cause warpage of the modules. Also, the

Hi David,
I've seen this a lot of times, and it was always caused by the diode
failing, which caused the diode to get very hot and would result in the
glass shattering. This was often obvious because the area around the diode
would become black and the module j-box would sometimes begin to melt.

Sometimes tempered glass will have a defect that will cause spontaneous
breakage from a relatively small stress in exactly the right spot. We
have seen that happen during module manufacturing, so usally it never makes
it out the door. What does the shatter pattern look like. If it is from
experience with that.
Best,
August

Hi David,
We have thousands of PV modules installed mostly on RV's. An RV roof can be a
very abusive environment with turbulence, flying debris, driving under limbs,
heavy vibrations and more. I have not had any glass breakage that could not be
accounted for, i.e, breaking for unknown reason. B
Wrenches,
I have a customer with one SW 230 poly V2.0 frame (top mount) module that
has shattered glass. It is on a DPW TPM10 pole mount. She noticed it the
other day and does not think that it was hit by anything. I agree that is
unlikely based on the site conditions.
