Abstract: In the current context, the most challenging and demanding research is to obtain maximum power from solar photovoltaic (SPV) power systems. Partial shadowing (PS) is a prominent cause of solar photovoltaic panels output power loss. The output decreases proportionally to the shaded area, the placement of shaded panels within the array, panel interconnections, shade pattern, etc. Numerous static and dynamic approaches for reducing the PS effect have been reported in the literature. Of these, the most common is the reconfiguration technique based on the static method, which distributes shaded panels more consistently and increases maximum power generation. The current study investigates the performance of common existing reconfiguration techniques based on static methods, including TCT, Sudoku, odd even (OE), and Latin square (LS) on a 4×4 PV array. The five different shadow patterns: short narrow (SN), short wide (SW), long narrow (LN), long wide (LW), and centre (CN) are implemented in this work. The performance analysis is carried out by comparing the maximum power generated (PM) and the results of panel simulations, as well as their theoretical conclusions, to ensure that these strategies are effectively implemented in hardware configuration.
