This standard specifies the test method for the rated Operating temperature of photovoltaic building integrated module cells. The standard covers the specific requirements of terms and definitions, test principles, test equipment, sample preparation, test procedures and test reports. It is applicable to crystalline and amorphous silicon solar cell modules and is mainly used for the evaluation of photovoltaic building integrated plane double-decked laminated Glass modules. Miscellaneous type plane double-decked laminated Glass film modules can be implemented with reference. The standard ensures that the average Operating temperature of solar cells is measured under standard environment conditions, providing necessary technical support for the promotion and application of photovoltaic building integrated technology.
