I haven’t seen this happen on our tempered glass PV modules but do wonder at times how much of a temperature variance 3 mil and 4 mil tempered can take before succumbing to the differential.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:navy'>Sincerely,<br><br>Chris Worcester<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:navy'>Solar Wind Works<br>NABCEP Certified PV Installer<br>Phone: 530-582-4503<br>Fax: 530-582-4603<br><a href="http://www.solarwindworks.com/">www.solarwindworks.com</a><br><a href="mailto:chris@solarwindworks.com">chris@solarwindworks.com</a><br>"Proven Energy Solutions"</span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p></o:p></span></p></div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>frenergy<br><b>Sent:</b> Wednesday, January 05, 2011 9:17 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Mitsubishi 170's<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Noblest wrenches,<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal> I have come upon the need for 1, Mitsu PV-MF170EB3. I have a customer here in snow country with a ground mount array. He says he shovels snow out from the ground in front of the rows of PVs and for 4 years has not been a problem until he noticed 2 of the PVs have their glass shattered, the entire piece. The most snow we've had on the ground so far this year is about 2 - 2 1/2 feet. The bottom of the PVs are about 14-18" off the ground. I could not see a point of impact. Anyone with similiar experience with this PV?<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal> I have one in stock, need one more.
