The core of photovoltaic module efficiency is the photoelectric conversion efficiency, which refers to the percentage of incident solar radiation energy converted into usable electrical energy by the module under standard test conditions (STC). It is the core technical indicator for measuring its ph

The Maximum Power Point (MPP) of a photovoltaic module refers to the working state of the module when the output power reaches its peak under specific irradiance and temperature conditions. The core parameters include the maximum power point voltage (Vm) and current (Im), and the product of the two
