Abstract: Abstract Photovoltaic (PV) systems are subjected to several environmental disturbances, one such a disturbance is partial shading, which adversely alters the characteristics of the photovoltaic system. Therefore, under Partial Shading Condition (PSC) there is a need to develop a complete analytical model of the PV system to investigate the most appropriate maximum power point tracking (MPPT) strategy in larger PV Systems. Based on the necessity, a precise analytical model of the PV system under PSC considering the effect of both series and shunt resistance is developed. The effects of temperature changes, irradiation changes, and effect for change in series, and shunt resistance and PSCs on electrical characteristics of the PV array are examined. A comparison was made with real-time data over the proposed and existing models during various PSCs. The results proved that the reliability of the proposed model is good, and it can be used to model different ranges of photovoltaic systems for both standalone and grid-integrated systems.
