What is the hot spot of photovoltaic panels
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. [1]. Thermography image of a PV module with visible hot spot in centered cell. It's important to know how hotspots impact system performance and potential reuse, and why anyone involved in solar decommissioning, repowering, or recycling should treat them as a diagnostic. . 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. This occurrence is usually triggered by the uneven distribution of sunlight across the solar panel, a scenario that arises when a specific section of. .
