Test Method PWM vs MPPT ?
I might get a chance to compare MPPT with my PWM on the set of two 100w panels. I get 12.6 (Isc) now with PWM so that is the "standard" I was thinking of a quick connect set-up to swap controllers...

In series it will likely pick a voltage that is little to low for one panel and ever so slightly too high for the other, which will put out maximum watts for the system overall at that point, unless the panels are badly mismatched for Amps at mpp or volts at mpp, which it sounds like they are not.
What is not clear to me in series is what the factors are when pulling the combined voltage of series panel down that determine the voltage of each individual panel. I think if I put a piece of foil in between the MC3 connections and pressed them together, it would five me a simple voltage tap between them to be able to determine the voltage of each.
