Test Procedures
Confirm normal status of the light source, temperature sensors, and irradiance probes before testing
Install photovoltaic modules according to standard requirements, ensuring the irradiated surface is perpendicular to the light source
Set irradiance intensity, test duration, and module surface temperature
Start the ultraviolet aging test and monitor system parameters in real time
Keep the chamber door closed throughout the test to prevent ultraviolet leakage
If irradiance or temperature exceeds preset limits, the system automatically cuts off the light source
After test completion, allow modules to cool to a safe temperature before removal
Maintenance Information
Regularly inspect xenon lamps and replace them according to specified service life
Periodically calibrate UVA and UVB probes to ensure measurement accuracy
Check temperature sensors and control systems for stable operation
Keep the irradiation chamber clean to maintain irradiance uniformity
Verify sealing components to prevent UV leakage and ensure operator safety
