Sorry to hear about the BP problems Andrew. For what it's worth you can tell BP that your story just solidified another wrench's reason to never sell any of their modules ever again.<div><br class="webkit-block-placeholder"></div><div>Hope you get the customer service you deserve, </div><div><br class="webkit-block-placeholder"></div><div><br class="webkit-block-placeholder"></div><div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div><div>Nick A Lucchese</div><div>NABCEP Certified PV Installer</div><div>Planet Home</div><div>General Contractor # 808851</div><div>Sierra Solar Systems</div><div>563C Idaho Maryland Road</div><div>Grass Valley, CA 95945</div><div>tech info and foreign orders: (530) 273-6754</div><div>order line: (800) 51-SOLAR (US only) FAX: (530) 273-1760 </div><div><a href="mailto:nickl@sierrasolar.com">nickl@sierrasolar.com</a></div><div><a href="http://www.sierrasolar.com">http://www.sierrasolar.com</a></div></div><div><br class="webkit-block-placeholder"></div><br class="Apple-interchange-newline"></span><br class="Apple-interchange-newline"> </div><br><div><div>On Jun 15, 2009, at 9:22 AM, Andrew Truitt wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><br>Greetings wrenches! We recently did a small commercial system (17 kW) using BP-SX 3175 modules and the Unirac RapidRac ballasted mounting system. The flat roof is ballasted with 2" of gravel that we smoothed as much as possible but undulations are visible in the array, though the changes are never more than 5 degrees from module to module. After about 3 months the cusotmer noticed a problem developing with 1/3 of the modules: the interior of the module (backsheet, cells and glazing) were separating from the aluminum frame! Remnants of the black, rubbery adhesive are clearly visible on the inside of the frame and on the edge of the backsheet/cell/glazing sandwich. It seems clear to us and that the adhesive simply failed and should be covered under the 5 year workmanship warranty, but BP does not agree. BP is saying that the modules are supposed to be mounted with a solid member spaning the width of the module and since the RapidRac supports the module on what amounts to 4 individual stanchions, the workmanship warraty is null and void. The mounting instructions, however, say nothing about requiring a solid member spaning the module.<br> <br>Has anyone else had this issue with BP or any other types of modules? Does anyone buy that it could be the fault of the RapidRac? We unbolted a few of the bad modules to see if the frame was exerting any torque but the neither the module not the frame moved - we set the module back on the frame and the mounting holes lined up perfectly as before.<br> <br><br>Thoughts or suggestions? <br><br><br>Gotta' love these long sunny days!<br><br><br>Andrew Truitt<br>Standard Solar Inc.<br><br clear="all"><br>-- <br>"Don't get me wrong: I love nuclear energy!
