DIN IEC/TS 63397 VDE V 0126-41:2025-12

Current safety standards of IEC 61730 series and design qualification and type approval standards of IEC 61215 series test for the ability of PV modules to withstand a defined hail impact. The requirements therein are the minimum for market entrance and are not written to propagate potential cell damage caused by the hail impact by subsequent mechanical and thermo-mechanical tests simulating the environmental stress modules will potentially be exposed to after hailstorms. The purpose of this document is to use selected tests of sequence C of IEC 61215-1:2021 figure 2, but to expose modules to hail stress prior to other stress tests and to compare the power loss caused by hail to reference modules. It can be used together with IEC 61215 series qualification or separately.
