According to IEC 60904, the effective irradiance of the two photovoltaic modules is calculated by measuring the short-circuit current and the back temperature of the module. The pollution loss is calculated by comparing the effective irradiance of the polluted photovoltaic module with the effective irradiance of the clean reference photovoltaic module. The calculation formula of the pollution loss index SLI is as follows:<\/p>\n
