Scope

GB/T 41314-2022 is the English-translated version of 建筑光伏组件用镀膜玻璃.

GB/T 41314-2022 is the Chinese national standard for the coated glass used in building-integrated photovoltaic modules.

It gives the classification, the requirements - the optical properties of the coating, its durability, the mechanical and thermal properties of the glass and its appearance - the test methods, the inspection rules and the provisions on marking, packaging, storage and transport.

It applies to coated glass for building photovoltaic modules, where the glass has to serve both as a façade element and as the front of a module. Glass makers, module makers and façade contractors use it. Issued on 9 March 2022, it has applied since 1 October 2022.
