<br>
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>
<br>
As always your invaluable input is always appreciated.<br>
<br>
Thanks,<span class="HOEnZb"><font color="#888888"><br>
