Performance enhancement of PV system using proposed array topologies under various shadow patterns

In this paper, a comprehensive study is carried out on the solar photovoltaic (PV) array topologies under diagonally shading scenario. The aim of extensive analysis is to investigate the power mismatch losses in PV array under non-uniform irradiations. The partial shading affects not only power but also exhibits extreme non-linearity along with multiple maximum power points on P-V and I-V characteristics. The investigation is based on designing...
