The performance of a photovoltaic (PV) array is affected by temperature, solar insulation, shading,
and array configuration. Often, the PV arrays get shadowed, completely or partially, by the passing clouds,
neighbouring buildings and towers, trees, and utility and telephone poles.
Under partially shaded conditions, the PV characteristics get more complex with multiple peaks. This makes the
tracking of the actual maximum power point (MPP) a difficult task. In this paper, a simple technique of MPPT is
presented for photovoltaic power generation system to solve the aforementioned problems. It realizes simple control
system to track the real maximum power point even under non uniform or for rapidly changing insulation
conditions.
