Before photovoltaic modules undergo thermal cycling and humidity-freeze testing, they are exposed to controlled ultraviolet radiation to evaluate the resistance of encapsulation materials, backsheet materials, sealants, and bonding interfaces to UV-induced degradation. This preconditioning process helps reveal potential weaknesses that may affect long-term outdoor performance. To satisfy photovoltaic qualification requirements, the UV exposure energy delivered to the module should reach: ①≥ 7.5 kWh/m² in the 280 nm–320 nm wavelength rang ②≥ 15 kWh/m² in the 320 nm–400 nm wavelength range. Throughout the test, the chamber maintains stable environmental conditions to ensure accurate, repeatable, and standards-compliant results.
