Replacing current 30A with MPPT controller - make sense?

Some of you have followed other posts of mine re: solar, and satellite, so hope this additional inquiry elicits similarly helpful info... If I knew then what I suspect now, I'd have had the Dealer ...

In a test I saw,a $15 PWM controller got 2 watts less than the Victron $$$ MPPT,in fact,all the different PWM controllers were only 2 watts lower than the various MPPT controllers..

So,I guess it depends on if those 2 watts are worth the huge step in price..Myself,I am trying to justify the MPPT controller price over the much cheaper PWM, for my upcoming solar instal.
