Hot spot temperature of photovoltaic panel
In photovoltaic (PV) systems, hotspots are localized regions on a solar module where temperature rises significantly above the nominal operating cell temperature (NOCT). This occurs when individual cells or sections within a module are electrically stressed due to shading, defects . . Thermography image of a PV module with visible hot spot in centered cell. It is a typical degradation mode in PV modules. [1] Hot spots can. . The hotspot effect is a phenomenon that occurs in everyday usage of solar panels. As a result, the panel gets heated and overloaded, which leads to a short-circuit that lowers output efficiency overall while hastening material deterioration.
