11.19 Stabilization (MQT 19)
This test of IEC 61215-2:2016 is applicable with the following modifications:
For the definition of stabilization as per test MQT 19 of IEC 61215-2:2016, x = 0,01 shall be used for crystalline silicon PV modules.
Temperature is a critical parameter. For the measurement MQT 06.1 of IEC 61215-2:2016 it shall be ensured that measurement is performed at (25 ± 2) °C module temperature.
11.19.4 Other stabilization procedures
At present no alternative stabilization methods are applicable.
11.19.5 Initial stabilization (MQT 19.1)
Initial stabilization of c-Si modules shall be obtained by exposing all modules to sunlight (either real or simulated) to an irradiation dose level of  10 kWh/rn2. After this preconditioning all of the test modules shall be measured for STC power (MQT 06.1).
To fulfil MQT 19 requirements two intervals of at least 5 kWh/rn2 each are required. If stabilization is performed outdoors no module temperature limits apply.
After stabilization time is not critical. Perform all measurements within a comparable timeframe and state time in report.
