In my case, there were visible hot spots that had burned through the backsheet in several places on several modules. In some places it was just small blisters, in others there was a clearly melted area of the backsheet. The hot spots seemed clearly associated with the cells that had cracks, but they were always at the edges and corners of cells. Unfortunately I did not have access to an IR camera to view them under load in the sun. </div><div class=""><br class=""></div><div class="">The manufacturer replaced them under warranty, but I\u2019m not pleased with these modules at all.</div><div class=""><br class=""></div><div class=""><br class=""><div class="">

<br class="">
I've had a colleague ask that I post a couple pictures of what appears to be cracks in cells under the glass. The glass is not damaged. These are Sun Edison modules, so apparently no warranty. Has anyone seen this, and are these possibly dangerous (hot spots) or is this nothing to worry about? An Infrared camera did not show any issues.<br class="">
<br class="">
As always your invaluable input is always appreciated.<br class="">

Thanks,<span class="HOEnZb"><font color="#888888" class=""><br class="">
