Photovoltaic module damp heat test chamber

The Photovoltaic Module Damp Heat Test Chamber is designed to simulate long-term tropical aging conditions for photovoltaic modules and related electronics. By combining high temperature and high humidity control, the system enables accelerated evaluation of module reliability, encapsulant degradation, and potential PID (Potential Induced Degradation) effects. It is suitable for R&D laboratories, quality assurance, and certification testing in compliance with international standards.

Application

Accelerated aging tests of photovoltaic modules under high temperature and humidity.

Evaluation of PID resistance and encapsulant performance.

Reliability testing of batteries, PV modules, and electronic assemblies in wet and humid conditions.

Indoor certification and R&D testing for IEC/UL compliance.

Test Procedures

Install test samples securely on the sample racks.

Set desired temperature and humidity profile using the touchscreen HMI.

Initiate the test cycle and monitor chamber conditions.

Record environmental data and any module performance changes throughout the test.

Complete the test and perform post-test inspection of modules or assemblies.

Export test reports for analysis or certification documentation.

Maintenance Information

Inspect heating elements, humidity sensors, and chamber seals regularly.

Clean interior surfaces and drainage channels to prevent mold or corrosion.

Verify calibration of temperature and humidity sensors periodically with NIST-traceable standards.

Replace worn or degraded components (heating elements, filters) according to operational hours.

Ensure safety interlocks and emergency systems are functional before operation.
