Abstract: Shadowing effect occurs when a photovoltaic system does not receive the same amount of incident irradiation level throughout the system due to obstacles. In these conditions, the cells receiving a lower level of irradiance can absorb. . Thermography image of a PV module with visible hot spot in centered cell. In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules. A good way to detect them is through thermography. Causes of Hot Spots Solar. . Have you noticed mysterious dark spots on your solar panels? These hot spots could be silently draining your system's performance and damaging your investment. Hot spots occur when shaded or defective solar cells overheat, potentially reducing panel output by 15-30% and causing permanent damage -. .
