<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto">I had the same experience as the older post you referenced with these mods on 2 MW system. Lots of burn marks and shattered glass, located at the edges of cells. And under thermal imaging there were clearly lots of issues, including ones that hadn’t (yet) manifested themselves to the naked eye. The mods were quite concave - a straight edge across the short side showed almost a half inch of concavity. I would have a very hard time using them again. Ok, let me rephrase - I would not. <br><br><div dir="ltr">Brian</div><div dir="ltr"><br><blockquote type="cite">On Jul 12, 2023, at 6:14 AM, Jason Szumlanski via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div dir="auto"><div>I was searching the forums for information on Peimar modules and this is all that came up.

<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><font color="#888888"><br>
