IEC 61464 Photovoltaic Panel Damp Heat Test Chamber

By simulating prolonged exposure to high temperature and high humidity, this chamber helps detect potential defects, predict long-term performance.

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.
