The Damp Heat Test Chamber is a high-precision environmental test device designed for evaluating the durability of photovoltaic modules under high temperature and high humidity conditions. By simulating prolonged exposure to extreme damp-heat environments in a sealed chamber, it assesses PV module materials, encapsulation, and electrical performance, providing critical insights into long-term reliability and resistance to extreme environmental stress.
Standards
The chamber complies with the following international standards:
(1) GB/T IEC 61215 – Crystalline Silicon Terrestrial Photovoltaic Modules – Design Qualification and Type Approval
(2) UL 1703 – Safety Standard for Photovoltaic Modules
