<div dir="ltr">Wrenches<div>To be sure you will need an IR Camera but yes it does happen one cell is failing and has become an energy consumer instead of a supplier, you will see a discolored cell and to the touch it will be noticeably hotter than the surrounding cells, I have seen this with several manufactures. I attached a pic of a module that was too hot to put your hand on on the failed cell. It may de difficult to get manufacturer assistance without a IV curve test on each module. You also should look at the back sheet as it may be discolored or even burned. </div><div>Jerry Shafer</div><div>NABCEP PV Inspector</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jan 8, 2021 at 11:23 AM Ray <<a href="mailto:ray@solarray.com">ray@solarray.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>HI All;<br>
</p>
<div>I'm forwarding this from a
friend and client of mine. I need to check to see what modules
these are, but it looks like we might have a high resistance
cell? Is this something that may go away once the modules warm
up, or is this an impending failure?</div>
