LIB Industry - Model IEC 61464 -Photovoltaic Panel Damp Heat Test Chamber
The IEC 61464 Photovoltaic Panel Damp Heat Test Chamber by LIB Industry is designed to simulate prolonged exposure to high temperatures and humidity. It is a crucial tool for identifying potential defects in photovoltaic panels and predicting their long-term performance. Suitable for all types of PV modules, from standard crystalline to large high-power panels, the chamber ensures precise temperature and humidity control with fluctuations as low as ±0.5°C and ±2.5% RH, respectively. The uniform airflow distribution guarantees consistent testing conditions, and its programmable multi-step test sequences enhance versatility. Crafted for reliability, the chamber's features include multi-directional airflow, a stainless steel interior to prevent condensation, and a customizable test space that accommodates various panel sizes. The control system includes a touchscreen interface for real-time monitoring and remote access via Ethernet, allowing for efficient management of extended tests.
The IEC 61464 Photovoltaic Panel Damp Heat Test Chamber is engineered for manufacturers and labs seeking to validate solar panel durability under extreme environmental stress, with a 85°C temperature and 85%RH humidity.

LIB Industry provides standard and customizable PV damp heat test chambers, suitable for all PV module types-from standard crystalline panels to large-format high-power modules. Our chambers feature precise temperature and humidity stability (±0.5°C for temperature and ±2.5% RH for humidity), uniform airflow distribution for consistent testing, and programmable multi-step test sequences. With these capabilities, our chambers are trusted by solar panel R&D centers, certification labs, and manufacturers worldwide.
Damp heat testing is critical for ensuring photovoltaic panels operate reliably in humid and high-temperature climates. It can reveal issues that may not be evident during normal operation:
- Delamination of encapsulants
– Moisture can compromise EVA layers, leading to reduced efficiency over time.
- Corrosion of busbars and solder joints
– High humidity accelerates chemical degradation and potential electrical failures.
- Hot spots and leakage currents
– Moisture penetration may trigger localized overheating, reducing panel lifespan.
- Frame and backsheet degradation
– Long-term exposure can weaken structural integrity, impacting safety and mechanical stability.
Using LIB Industry's IEC 61464 Photovoltaic Panel Damp Heat Test Chamber, engineers can identify these vulnerabilities early, optimize PV design, and confidently deliver modules for harsh environments.
