JJF 2022-2023 "Specification for calibrating ultraviolet aging boxes for photovoltaic modules" applies to the calibrating work of ultraviolet aging boxes for photovoltaic modules. This specification refers to the terminology standard for solar photovoltaic energy systems GB/T 2297-1989 and the performance classification standard for photovoltaic devices IEC 60904-9. The terminology section defines ultraviolet irradiance, i.e., the flux of ultraviolet radiation in the 250~ 400nm band per unit area. UV aging boxes are used to simulate the ultraviolet portion of the solar Light spectrum and evaluate the UV radiation resistance of photovoltaic modules by providing specific UV irradiance and temperature conditions (usually (60 +/- 5) ° C). Light sources are arranged on the side or on the top for aging tests of photovoltaic modules to verify their performance Stability and durability under long-term ultraviolet irradiation.
