A Study on the Output Characteristic of Photovoltaic Array under Partially Shaded Conditions

Abstract:

Efficiency of Photovoltaic (PV) array is affected by surface temperature, solar irradiance, shadow and shape of the PV array. Under partially shaded conditions, the maximum power point tracking method will be hardly controlled since the output power characteristic of the PV array is complex with many spikes. In the present study, characteristics of PV array were therefore established under partially shaded conditions by using Matlab/Simulink. The output characteristics of the PV array under partially shaded conditions were calculated and analyzed. These output characteristics significantly depend on the solar irradiance, surface temperatures, cases of shadows, configurations of the PV array, and numbers of PV modules under partial shadow. The present results are good to designate a PV power generation system by using the power point tracking method.
