Solar photovoltaic (PV) systems provide clean energy but are highly affected by shading. This study analyzes how shading from trees, buildings, dust, or clouds reduces system efficiency and power output. It focuses on the impact of partial shading on I–V and P–V characteristics, where multiple power peaks make maximum power point tracking (MPPT) difficult. Shading can also cause hot spots, leading to potential damage of PV modules. The use of bypass and blocking diodes, along with proper system design and panel placement, helps reduce these effects. This work highlights practical methods to improve the performance and reliability of PV systems under shading conditions.
