FWIW... I use MPPT (usually Victron) on my fixed array sites where for whatever reason I am limited for panel size and need to milk as much juice as I can.
Whenever I can use larger panel capacity I use PWM (usually Morningstar).
The MPPT sites are good for maybe 10% possibly 15% more juice... hard to put a figure on it as it differs from month to month... MPPT is def better in the south of WA tho, but PWM closes the gap the further North you go esp Kimberley/Pilbara
