Method and apparatus for calculating power generation capacity loss of photovoltaic assembly, and electronic device

An apparatus for calculating a power generation capacity loss of a photovoltaic module, comprising:

• a data calculation module, configured for acquiring fault information of a photovoltaic module and calculate an area proportion and a power generation capacity loss influence coefficient that correspond to the fault information;
• a first loss calculation module, configured for calculating a difference between an actual power generation capacity and a theoretical power generation capacity of a photovoltaic string at which the photovoltaic module is located and determine the difference as a power generation capacity loss of the photovoltaic string;
• a second loss calculation module, configured for calculating a module power generation capacity loss corresponding to the fault information based on the power generation capacity loss of the photovoltaic string, and the area proportion and the power generation capacity loss influence coefficient that correspond to the fault information;
• and
• a third loss calculation module, configured for calculating a total power generation capacity loss of the photovoltaic module based on the module power generation capacity loss.
