Study of Partial Shading Effect on the Different Photovoltaic Array Arrangements and their Shade Resilience

Due to its ability to directly and cleanly convert solar radiation into electricity, the use of photovoltaic (PV) technology is rapidly increasing. Solar PV panels are connected in various series and parallel configurations to achieve the necessary output voltages and currents. They perform optimally when completely unshaded, but when a series connection is partially shaded (PS), bypass diodes activate and the overall voltage drops, resulting in reduced power generation. The location of bypass diodes, series-parallel combination types, and shading patterns all impact the output power. Therefore, selecting the appropriate PV panel arrangement can potentially increase output under these conditions. This study analyzes the shade resilience ability of series-parallel (SP), Total cross-tied (TCT), Bridge-linked (BL), and Honeycomb (HC) configurations.
