<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">We recently bought some broken modules from a supplier --at a very good price- to see if we could work something out. After looking into a variety of options we settled on a lexan sheet cut to size and secured with polyurethane adhesive along the frame edges. The reason we chose lexan was due to the fact it is flexible and the broken modules we purchased actually had a convex shape due to the impact they received. The polyu worked well on the module with an aluminum frame but did not like the one with a painted frame so much. The problem we couldn't solve is the loss of Voc & Isc due to refraction & reflection from the broken bits of glass. Removing it did not seem like an option.<div><br></div><div>Ron Young<br><div><br><div><div>On 27-May-10, at 8:11 AM, Joel Davidson wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; 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: 0px; "><div bgcolor="#ffffff"><div><font size="2" face="Arial">Jeff,</font></div><div><font size="2" face="Arial"></font> </div><div><font size="2" face="Arial">You can put another glass front on top of the module to protect the cells and wiring to get a few more years use from the module.
