11.19 Stabilization (MQT 19)
This test of IEC 61215-2:2021 is applicable with the following modifications:
11.19.1 Criterion definition for stabilization
For the definition of stabilization as per test MQT 19 of IEC 61215-2:2021, x = 0,01 shall be used for
crystalline silicon PV modules.
11.19.2 Light induced stabilization procedures
This test of IEC 61215-2:2021 is applicable without modifications.
11.19.3 Other stabilization procedures
This test of IEC 61215-2:2021 is applicable without modifications.
11.19.4 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/m 2 . 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/m 2 each are required. If stabilization is performed outdoors no module temperature limits apply. A validated alternative procedure can be used in accordance to MQT 19 of IEC 61215-2:2021 After module stabilization, the timeframe for the subsequent tests is not critical. Perform all measurements within a comparable timeframe and state time in report. 11.19.5 Final stabilization (MQT 19.2) Final stabilization (MQT 19.2) is not required, except for modules that have been tested according to MQT 21, Potential induced degradation test (in sequence F), or MQT 13, Damp heat test (in sequence E). Final stabilization requirements differ depending on whether the module has been subjected to MQT 13 or MQT 21. For modules that have been tested according to MQT 13, damp heat test (in sequence E), a choice of two final stabilization methods, “Method 1” or “Method 2”, is available: Method 1) • Perform MQT 19.3 as defined in IEC 61215-2. • Record choice of stabilization method 1) in the test report.UL 61215-1-1-2021 pdf download.
