Re: [RE-wrenches] Solar World shattered module

[Allan Sindelar]

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 modules on every one of their racks with which I have worked hold the individual modules apart from each other, typically at least 1/4". So I would not suspect the rack as the cause. Others have made good suggestions: check the shatter pattern - it could be a hot spot, it could be a flaw in the tempered 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.   David Palumbo Independent Power LLC 462 Solar Way Drive Hyde Park, VT 05655 (802) 888-7194   _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Change email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
