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.

Application

The Damp Heat Test Chamber is suitable for:

Damp-heat performance testing of photovoltaic modules

R&D and quality control of PV modules

Type certification and qualification tests

Indoor laboratory simulation of outdoor high temperature and humidity

Accelerated aging and lifespan evaluation of PV modules

Environmental adaptability studies and standard verification

Scientific research and laboratory durability studies

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
