Zoomed in on the one bad panel. Good news it it can be tested in-situ, so no need to disconnect anything to inspect for failing panels. Works best during operation.

Those were Sharp 165W. Now for AstroPower 120W and SunPower 327W

Two panels as power source, producing 79 Voc, 41V @ 2A into panel under test
