[RE-wrenches] Solar World shattered module

[Larry Crutcher, Starlight Solar Power Systems]

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. But, we have had hoodlums shooting at PV modules. Perhaps look at the back for a hole.

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.
 
Other than by a falling tree, thrown rock, or twisted frame – is there another way that glass shatters on a 65 degree tilted pole mount like this?  We installed the system 2 years ago. The module was on the lower corner of the array.
·         Is it likely that this modules frame was being pressured by the module(s) above it? TPM has two rows of 5 modules in landscape, so this bottom module has 4 modules mounted above it. Again it is a top mounted DPW pole array.
·         Or, is there another way that glass shatters on this type of module?
I have not visited the site yet, just received the phone call today.
