Damp Heat Chamber For Solar Panels

MODEL NO: AI-182

ACCUMAX INDIA Damp Heat Chamber for Solar Panels

A damp heat chamber for solar panels is a specialized environmental testing device that simulates harsh tropical conditions (like 85°C and 85% humidity) to accelerate aging and test the long-term durability, moisture resistance, and overall reliability of PV modules, checking for issues like delamination, corrosion, and connection failures as per standards like IEC 61215. This accelerated aging helps manufacturers identify weaknesses early and ensures panels can withstand real-world humidity and temperature stress over their lifespan.

Purpose of the Test

• Moisture Ingress: Determines how well the panel’s lamination and edge seals prevent moisture from getting in.
• Material Degradation: Checks for issues like corrosion, delamination (separation of layers), and potential electrical failures.
• Performance Validation: Ensures the panel maintains its power output and structural integrity over time, even in humid climates.

Key Test Conditions (IEC Standard)

• Temperature: 85°C (± 2°C).
• Relative Humidity (RH): 85% (± 5%).
• Duration: Typically 1,000 hours (over a month).

What it Tests For

• Junction Box Failures: Connections and sealing integrity.
• Corrosion: On metal parts and interconnects.
• Delamination/Peeling: Separation of the encapsulate from glass or back sheet.
• Cell Damage: Visible defects or power loss in the PV cells.

Importance

It’s considered a critical test for PV module certification, especially for ensuring quality in demanding tropical environments, and helps prevent costly field failures by predicting long-term performance.

Introduction

A Damp Heat Chamber is device that simulates a variety of climate conditions, including humidity and temperature, to test a material’s performance. Damp heat chamber are used to test materials for their resistance to heat, cold, dryness, and mugginess.
