This study investigates five rearrangement methods for photovoltaic arrays, focusing on the module parameters Im, Isc, Pm, Vm, and Voc. These techniques address the issue of photovoltaic (PV) module mismatch power loss and a decrease in power output due to inconsistencies between individual solar cells within a module or between multiple modules within an array. The aim is to enhance the efficiency, reliability, and affordability of PV systems by minimizing mismatch power loss. The study evaluates the effectiveness of various optimization strategies in reducing mismatch power losses in PV arrays, both in newly installed and aging systems. Six combinations (20×2, 10×4, 8×5, 2×20, 4×10, and 5×8) were analyzed to determine the impact of mismatch losses (MML). To gauge the effectiveness of the proposed techniques, the study used SP array topologies in 40W, 80W, 250W, and 10W arrays. As PV systems become more prevalent, improving efficiency becomes crucial to maximize energy production. Shadowing, aging, and manufacturing tolerance contribute to significant mismatch losses, affecting overall PV array performance. This research assesses the effectiveness of optimization algorithms in mitigating mismatch losses under both original and degraded conditions. By comparing the performance of new and 5-year-old PV arrays, the study identifies the most effective mismatch power loss minimization technique. Practical implementation on a 10W aged PV array resulted in a 3.87% increase in output power, demonstrating the method's efficacy. The findings of this research have direct implications for the design and operation of PV systems, making the relevance and applicability of the findings clear to the reader.
