outback solar mppt controller
anyone had any experience with the outback mppt controllers? I see solar blvd has a 10A for $99 and a 20A for $149. the 20 A would be a nice update from the morningstar 15A at a reasonable price...

What do you mean "much confusion"? You just did all the math to prove my point. The MPPT controller gives you more amps out in both of your calculations.
By the way, increased panel temperature, wire loss, and controller loss all come into play with PWM controllers too.
Ok you were not confused. :) However the PWM is not affected by the panel heating since the Isc goes up with higher temps, so you still get rated Isc for your amps with panel aimed.
The lower Imp for the panel has no meaning with PWM. Your higher panel Isc rating is the "expected amps" to the battery at STC with PWM.
