During the application process of solar modules, they will withstand various severe weather tests. Among them, the ability of the module to withstand high temperature and high humidity and the subsequent low temperature, and the ability to withstand long-term moisture penetration need to be evaluated. HF environmental simulation test can verify and evaluate the reliability of components or materials, and identify manufacturing defects early by inducing failure modes through thermal fatigue.
