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...

You are absoulute correct. I was just picking a typical Vmpp for a typical 12volt panel to do an estimate of max amps provided. Your correct in that Vmpp is panel specific. I was just estimating the difference in amps provide via PWM and MPPT assumming I could drive the solar panels at max capability under both setups.
Getting the actual data results will be interesting to see how close those estimates are and how close the claims from MPPT manufacturers are in some simulated real world conditions
