|---|---|
● Thermal cycling test: Cycling between 85°C and -40°C at 100°C/hour maximum
● Humidity freeze cycle: climatic cycle with humidity control and temperature 85°C / 85%RH and -40°C;
● Damp heat test: specifically designed to perform long term tests (85°C; 85% RH: 1000 hours)
Advantages
1. Integrated Thermal, Humidity-Freeze, and Damp Heat Testing for PV Modules: The chamber supports full-cycle PV module testing, including thermal cycling (–40 °C to +85 °C), humidity-freeze cycling (85 % RH, –40 °C to +85 °C), and damp heat testing (85 °C/85 % RH). This integrated capability allows engineers to evaluate mechanical, electrical, and encapsulation reliability in a single unit, eliminating the need for multiple test systems.
2. High-Precision Control for Repeatable Results: Equipped with PT-100 Class A temperature sensors and PID controllers, the chamber maintains temperature within ±2 °C and humidity within ±2.5 % RH. Uniform airflow and calibrated sensors ensure that each PV module experiences the same conditions, guaranteeing consistent, traceable, and audit-ready test data for R&D, QA, and certification purposes.
3. Large Capacity and Flexible Sample Handling: The chamber accommodates panels up to 2 m(customized) in size, with adjustable racks supporting more than two modules per run. Customizable holders, cable holes, and vertical mounting options allow secure placement of various PV types.
4. Energy-Efficient, Eco-Friendly Operation: Advanced compressor-based cooling and intelligent humidification systems provide rapid temperature transitions and stable humidity control while reducing energy and water consumption. Automatic condensation recycling and low-water alarms ensure uninterrupted long-term damp heat tests up to 1000 hours, supporting sustainable lab practices.
5. Safe, Durable, and User-Friendly Design: Built with SUS304 stainless steel interiors and powder-coated A3 steel exteriors, the chamber resists corrosion, chemical exposure, and mechanical wear. Safety features include over-temperature/pressure protection, fail-safe power shutdowns, and insulated observation windows. A multilingual touchscreen interface allows intuitive programming of thermal, humidity-freeze, and damp heat cycles for quick setup and monitoring.

Operate Guide of the Environmental Test chamber for PV Solar Panel
Before starting, ensure the chamber is properly connected to power and water supply and that all safety interlocks are in place. Set the desired test profile using the color touchscreen controller, including thermal cycling, humidity-freeze cycling, or damp heat conditions according to your PV module requirements. Load the modules securely on the adjustable racks, ensuring proper inclination and spacing for uniform exposure. During the test, monitor temperature, humidity, and cycle progress via the display or through Ethernet/USB data logging. After completion, allow the chamber to return to ambient conditions before removing the samples. Regular maintenance, including water filter replacement and inspection of seals, will ensure accurate and reliable long-term operation.
