The Photovoltaic Module Damp Heat Test Chamber is designed to evaluate the long-term reliability of PV modules under high-temperature and high-humidity conditions. By simulating extreme tropical and subtropical climates, it accelerates aging processes to verify module performance, insulation integrity, and resistance to potential degradation mechanisms such as PID (Potential Induced Degradation), encapsulant yellowing, or delamination.

The chamber provides precise control of temperature and humidity, enabling manufacturers, laboratories, and certification bodies to ensure compliance with IEC, UL, and ISO standards.

Applications

This test chamber is widely used for:

PV module qualification and type approval testing

Accelerated aging simulation for tropical climates

PID resistance and encapsulant degradation studies

Quality control in PV manufacturing lines

R&D for module materials, coatings, and encapsulation techniques

It is also suitable for testing batteries, PCBAs, and sensitive electronics under damp heat conditions.

Applicable Standards

The chamber complies with international and industry standards:

IEC 61215 – Terrestrial PV Modules: Design Qualification and Type Approval

UL 1073 – Safety for Enclosures for Electrical Equipment

ISO 16750-4 – Road Vehicles: Environmental Conditions and Testing for Electrical and Electronic Equipment

CE Certification – Conformité Européenne compliance

These standards ensure reliable, repeatable testing results for global certification and product reliability.
