A High-Resolution Approach for Performance Estimation of Photovoltaics Under Partial Shaded Conditions Fuxiang Li, Wei Wu



Partial shaded conditions (PSC) significantly affect the performance of photovoltaic (PV) systems. Understanding and mitigating PSC effects require an accurate model with the ability to simulate the PV operating in both forward and reverse biased regions. Herein, a high-resolution approach is presented to address this issue. The reversed biased effects of PSC are fully considered at the cell level using an enhanced single diode model. Based on this, the electrical characteristic of the PV module can be accurately calculated. Good agreement is obtained between the simulation and measurement with a maximum relative error of 6.1%. This approach provides a useful tool for comprehensive modeling of the PV system.
