Test Procedures
Prepare the test water according to standard requirements and adjust the resistivity.
Start the water temperature control system and stabilize the temperature at 22 ± 3 ℃.
Fix the photovoltaic module on the sample holder and complete electrical connections.
Activate the spray system to ensure uniform wetting of the module surface and frame.
Increase the test voltage at a controlled rate of 500 V/s until the specified value is reached.
Maintain the withstand voltage and measure leakage current and insulation resistance.
Record test results and determine compliance based on standard leakage current limits.
