I think these modules are about 12 years old. I didn't have a
voltmeter or ammeter with me this morning when this was discovered
so I wasn't able to check the output.<br>

<div>Found some damage to a customer's Grape CS-S-180-DJ PV
modules this morning. Unlike anything I've ever seen; so I'm
hoping that someone on this list can tell me the cause. I've
put several <a href="https://drive.google.com/drive/folders/1nQhTqahEx4whmmWyy89tqaEEGvzkvEps?usp=sharing" target="_blank" rel="noopener noreferrer" moz-do-not-send="true">photos of the cells online</a> so
you can inspect them. While it looks like there has been
some localized heating on the traces, there isn't any
evidence of damage on the rear of the PV modules. These are
on an off grid system charging some 12-volt batteries.
Thanks.<br>
