Effect of Partially Shaded Conditions on Photovoltaic Array’s Maximum Power Point Tracking

Maximum power point tracking algorithm is widely implemented in photovoltaic system to maximize the PV array output power. In general, Perturb and Observe (P&O) is simple thus being selected to continuously track the array maximum power point (MPP). Under uniform solar irradiance, PV array chara...
