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...

Ambient temp for test will be say 23C. Tilted panels, air cooled. Voc might be usually seen 20.3ish instead of rated, so I suppose you could figure panel temp working back using the Sharp voltage coefficient. ISTR you are supposed to add about 20C to ambient when we looked at all that a while ago. It varies though.
I think maybe my wiring lash-up that does not now matter with PWM might be unfair to the MPPT, or at least screw up your estimates. PT keeps saying that. I don't care if it is unfair to the MPPT. If it can't do the job-- too bad! :)
