Scope

Scope: This standard primarily specifies the power attenuation testing technology for photovoltaic modules during their lifespan, including terms and definitions, technical requirements, test methods, handling of discrepancies in results among testing institutions, packaging and transportation, testing rules, and test reports. This standard applies to power attenuation testing of flat-type crystalline silicon photovoltaic modules in normal operation. Main technical content: The standard consists of nine sections: scope, normative references, terms and definitions, technical requirements, test methods, handling of discrepancies in results among testing institutions, packaging and transportation, testing rules, and test reports. (1) Scope: Specifies that this standard applies to power attenuation testing of flat-type photovoltaic modules in normal operation. (2) Normative references: Lists four standards referenced in this standard. (3) Terms and definitions: Describes six important terms and definitions related to this standard. (4) Technical requirements: Includes power attenuation rate, appearance, and EL images. (5) Test methods: Includes sample pretreatment, maximum power measurement, appearance inspection, and EL testing. The sample pretreatment section specifies that the surface of the tested samples should be clean before testing. The cleaning process should not affect their performance. If the cleaning process may affect the performance of the samples, this should be noted in the report. Maximum power measurement and appearance inspection are performed in accordance with IEC 60904:2006 and IEC 61215-2:2006. EL testing uses current parameters no less than 0.6 times the nominal short-circuit current based on the sample information. Low-current EL testing is optional and generally no more than 0.2 times the nominal short-circuit current. The spatial resolution of the testing equipment should meet the requirements of Class A or higher as specified in
