Comments on Mismatch Effects


I have often run into situations in the field where my modules from one array have a higher Voc and are pushing reverse current through the other arrays installed in parallel with it and I was wondering if there was a calculation that I could use that by measuring the current flowing from the higher voltage array to the lower voltage array that I could then determine the potential difference between the two arrays. Thanks. I am still new to the industry so be sure to make it simple.
