Hotspots can arise from a mix of environmental, mechanical, and electrical issues, and one of the most common causes is partial shading. A tree branch, a patch of dust, or even a single leaf can block sunlight to one or more cells, creating an imbalance in light exposure. . The hotspot effect is a phenomenon that occurs in everyday usage of solar panels. Keep reading;. . This occurrence is usually triggered by the uneven distribution of sunlight across the solar panel, a scenario that arises when a specific section of the panel is shaded or receives less sunlight in comparison to the surrounding areas. As a result, the panel gets heated and overloaded, which leads to a short-circuit that lowers output efficiency overall while hastening material deterioration. Individual solar cells are connected in a series of crystalline silicon solar modules.
