THE EFFECT OF IRRADIANCE SOLAR POWER ON PV MODULES POWER
Hot spot effect of solar photovoltaic power generation
The abnormal heating in hot spot areas leads to a rapid decline in the performance of local solar cells, subsequently reducing the power generation efficiency of the entire photovoltaic module. Research data shows that a single hot spot can decrease the power output of a module by 5% -. . 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. [PDF]
