The IEC 61701:2020 standard specifies the salt fog corrosion test method for photovoltaic modules, which is mainly used to evaluate the corrosion resistance of modules to chlorine-containing salt fog (such as NaCl, MgCl2). This standard provides a comprehensive description of the corrosion resistance of photovoltaic modules and is applicable to various photovoltaic tests, including the requirements of IEC 61215, IEC 61646 and other related standards. The test results help to ensure the long-term Reliability of photovoltaic modules in salt environments and are widely used in the design and quality control of photovoltaic modules.
