A Maximum Power Point Tracking (MPPT, as you mentioned) controller should maximumize the power from your array by adjusting the voltage output of the array for maximum power. Each solar cell, and thus each panel, and thus your array functions as a current source. Presuming your array has the panels in parallel, running the least performing panel at a higher terminal voltage in order to get more power out of the better performing panel(s) is what an MPPT controller should do for your array, thus performing its best throughout the day.
