Hi Corey,
I recently commissioned a large system and saw something very similar. Is
it possible that there is a minor amount of shading on those modules? Maybe
weeds growing up or powerlines? When I had noticed that cell pattern, it
took a little bit to realize that there were powerlines just south

I consulted and did some independent tests with a module manufacturer who
had some modules with low Power output and curve traces similar to yours.
They however could detect no abnormal cracks in the modules with EL
testing. I also detected no issues on the thermal image at no or low power,
ts with a grain of salt. If anyone sees somewhere

I've checked several PV modules under load in past years and they all
seem to do this.
Just cell mis-match I was guessing.
