Another Panel Mixing Question

mjp24coho

I know his topic has been discussed many times before, but I'm still confused based on my potential application. I have 4 panels that I want to combine - 3 are Kyocera 245W and one is a Kyocera 205W. I want to wire one 245W with the 205W in series, the other two 245W panels separately in a series, and then combine the two strings in parallel (using my combined box). The specs for the 205 are: Vmp 26.6, Voc 33.2, and Imp 7.71. The specs for the 245s are Vmp 29.8, Voc 36.9, and Imp 8.23. I know I should keep the variance under 10%, but is that Imp, Voc, or Vmp? In this case, Imp variance is 7%, Voc is 11%, and Vmp is 12%. Would that work?

It should work (no damage). You might lose 7-11% of your output on the mismatched panels.
