Good morning – this will probably start showing up as ground fault issues due to current leakage. You may want to identify the cracked backsheet modules and isolate them from the string (bypass or jumper the module). This would probably be classified as a materials and workmanship defect and that part of your warranty may have expired.

Please take care when clicking links or opening attachments. Hi All, We have discovered quite a few modules at a particular site that are showing cracking in the back sheets. It appears these modules are not underperforming yet, but we assume it’s a matter of time before they all water and start causing the glass to shatter. Some of the modules at this site are at that shattered glass stage. I’m assuming we should thermal image and keep an eye on potential hotspots, but any other advice would be great to hear. Full removal isn’t out of the question, but this is about 40% of a 1MW rooftop system.
