The Study of Partial Shading on Mono and Poly Crystalline Photovoltaic Modules in Southern Rajasthan
Manoj Lakhan [2] | Ram Kumar Mathur [2]
Abstract: In this modern world energy has become an integral part of our daily life. Research is going on for creating a proper way to get power from non - conventional sources which are harmless to environment and human society. The performance of PV panel is affected by shading effect due to trees, passing of clouds, neighbouring buildings and any other medium. Partial shading of solar cells can have detrimental effects on the overall efficiency and performance of a solar panel. When some cells within a panel are shaded, they generate less electricity than the un - shaded cells, creating an imbalance in power output. This imbalance can lead to hotspots, where the shaded cells can experience higher temperatures due to reduced electrical generation. Hotspots not only reduce the efficiency of the solar cells but can also lead to long - term damage, affecting the overall lifespan of the solar panel. Bhilwara is situated in the semi - arid lands of southern Rajasthan of India, experiences abundant sunlight throughout the year, making it an ideal location for solar energy generation. However, the efficiency of solar panels can be significantly impacted by shading, especially in densely populated areas or regions with uneven terrain. In this research paper we explore the shading effect on both mono crystalline and poly crystalline solar modules in the context on environmental and climatic condition of Bhilwara. It is observed that partial shading affects both mono crystalline and poly crystalline solar modules similarly; however, their responses to shading differ. Mono crystalline modules typically perform slightly better in low - light conditions, thereby handling partial shading more efficiently. In contrast, poly crystalline modules may experience a somewhat greater reduction in efficiency under the same conditions.
