Damp heat testing can reveal various defects, such as delamination, deterioration of glass surface (AR coating), frame corrosion, metal grid discoloration and junction box attachment and connection failures. The Damp Heat test is an environmental quality test and one of the qualifying tests for IEC 61215.
Wet Leakage Current Test Confirms the Safety of the Module in Wet Conditions Solar modules need to operate reliably and safely when soaked in water. Whether it's in the rain, fog, dew or melted snow, the solar module should provide good insulation to make sure the system operators are safe around the PV system.
Prolonged exposure to heat and humidity can deteriorate a poor quality solar module as condensation enters through gaps and perforated films to ruin the solar cells. Damp Heat (DH) is defined in IEC 61215 to put a solar panel through a gruelling heat and humidity combination to understand how well the panel can survive in a tropical environment.
Damp Heat (DH) is defined in IEC 61215 to put a solar panel through a gruelling heat and humidity combination to understand how well the panel can survive in a tropical environment.
The Damp Heat test is carried out before Mechanical Load testing and Wet leakage current test is performed before and after the test. Even if no major defects are detected after DH1000 (Damp Heat testing for 1000 hrs), the module is then stressed to the point that it becomes more fragile for the subsequent mechanical load testing.
