  • Solar Panel Hot Spots

    Solar Panel Hot Spots

    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.


    FAQs about Solar Panel Hot Spots

    How does a hot spot affect a solar panel?

    Hot spots result in increased resistance in affected cells, leading to power dissipation as heat. This energy loss reduced the overall power output of the panel, resulting in lower efficiency and decreased electricity generation. The higher the number and severity of hot spots, the greater the impact on the panel's overall performance.
