Popis: Improving photovoltaic (PV) system efficiency is a popular field of research. Partial shading (PS) adversely impacts the solar system's output power, which considerably reduces the system's efficiency. As a result, this issue has been the subject of extensive investigation. When sunlight is blocked off of photovoltaic cells in a PV array, panel, or module, it is referred to as shading. Using a method that involves spreading shade throughout the PV array is one of the suggested fixes for this issue. This study compares the performance of a shade dispersion method to different PV array configurations under different partial shading circumstances, and it looks at how effective it is in a 3x3 PV system. MATLAB/Simulink is used for the evaluation. To achieve this, shade dispersion-based TCT (SD-TCT) under various shading scenarios has been compared to the current standard designs, which include series-parallel (SP), Honey-Comb (HC), Bridge-Linked (BL), and Total Cross-Tied (TCT). Based on the global maximum power (GMPP), mismatch power losses, fill factor (FF), percentage power losses (PL %), and PV system efficiency, the efficacy of the shade dispersion technique was assessed. For every partial shading condition (PSC) that was studied, the SD-TCT configuration outperforms the other setups in terms of fill factor and power loss.
