[RE-wrenches] Damaged PV module cells

[Kent]

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 photos of the cells 
online 
<https://drive.google.com/drive/folders/1nQhTqahEx4whmmWyy89tqaEEGvzkvEps?usp=sharing> 
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.
