Abstract - Partial shading in photovoltaic systems indeed poses significant challenges, potentially leading to mismatch power losses and reduced overall efficiency. Addressing this issue is crucial for maximizing the performance of solar energy systems, especially as they become more prevalent in power production globally. In the context of a 4×4 Total Cross Tied (TCT) PV array with 10W panels, the impact of partial shading on the system's efficiency and power production must be thoroughly analyzed. Techniques that can effectively mitigate mismatch power losses caused by partial shading are essential for optimizing the performance of such arrays. Testing the performance of the PV array under various partial shading conditions is crucial for evaluating its effectiveness. This empirical analysis helps in understanding how different shading scenarios affect the array's output and how mitigation strategies can improve overall efficiency. Efforts to reduce Percentage Power Loss (PLL) while enhancing efficiency are essential for ensuring the economic viability and sustainability of solar energy systems. By developing and implementing effective techniques for managing partial shading, we can improve the reliability and effectiveness of photovoltaic systems, thus accelerating the transition to clean and renewable energy sources.
