By performing \u003cstrong\u003eMaximum Power Point Tracking (MPPT) at each individual panel\u003c\/strong\u003e, it keeps every module producing at its own optimum independently of the rest of the array, so shading, soiling, ageing or manufacturing mismatch on one panel no longer drags down the whole string.
