Zusammenfassung:This paper addresses the challenge of evaluating the impact of partial shading conditions (PSC) on individual photovoltaic (PV) cells (Cell-PSC) within a PV panel. The study introduces a comprehensive and generalizable methodology involving experimental tests on different PV panels under different Cell-PSC scenarios, emulating bird-droppings. Analysis of the I-V curves reveals complex relationships, with variations in Maximum Point Power (MPP) voltage and power influenced by temperature changes in the affected cell. Furthermore, the study examines the fill factor and the area enclosed by the I-V curve. In addition to experimental investigations, the research employs a detailed quantification process through simulations utilizing the double diode model. This illustrates the impact of partial shading conditions on incident irradiance and temperature over the affected cells. The findings contribute valuable data for the future development of real-time anomaly detection algorithms, offering a significant understanding of PV system performance under Cell-PSC.
