This study highlights the critical importance of reconfiguring photovoltaic (PV) arrays to optimize energy production despite various forms of shading. The research shows that reconfiguration, whether static or dynamic, has been widely explored in different PV array topologies. A detailed modeling of PV arrays is first presented, including evaluation criteria and behavioral analysis. This preliminary study establishes the necessary foundation for a comprehensive understanding of the system and the exploration of advanced optimization methods. Two optimization methods through reconfiguration are then proposed. The first method, called modified SP, involves transitioning from the series-parallel (SP) circuit to the Total Cross-Tie (TCT) circuit, known as SP-TCT. The second method, SP_RECFG, allows for the redistribution of solar modules affected by shading. Simulations show that these approaches optimize the power output of PV arrays even in complex shading scenarios. A comparative study also demonstrates the superior efficiency of the SP_RECFG method. Additionally, the theoretical approaches have been experimentally validated. The SP-TCT method was successfully implemented, minimizing power losses due to partial shading. This research demonstrates that reconfiguring PV arrays is essential for maximizing solar energy production and contributing to a sustainable energy transition.
