UL 61215-1-1-2017 pdf download.Terrestrial photovoltaic (PV) modules – Design qualification and type approval – Part 1-1: Special requirements for testing of crystalline silicon photovoltaic (PV) modules.
This part of IEC 61215 lays down IEC requirements for the design qualification and type approval of terrestrial photovollaic modules suitable for long-term operation in general open air climates, as defined m IEC 60721-2-1. This standard Is intended to apply to all crystalline silicon terrestrial flat plate modules.
This standard does not apply to modules used with concentrated sunlight although it may be utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests are performed using the current, voltage and power levels expected at the design concentration.
The object of this test sequence Is to determine the electrical and thermal characteristics of the module and to show, as far as possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in climates described in the scope. The actual lifetime expectancy of modules so qualified will depend on their design, their environment and the conditions under which they are operated,
This standard defines PV technology dependent modifications to the testing procedures and requirements per IEC 61215-1:2016 and IEC 61215-22016.

11.19 Stabilization (MQT 19)
Thés test of IEC 6121 5-2:2016 is applicable with the following modifications:
Fo the definition of stabilization as per test MOT 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 MOT 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 (MOT 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/ma. After this preconditloning all of the test modules shall be measured for STC power (MOT 06.1).
To fulfil MOT 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 withén a comparable timeframe and state time in report.
