IEC 61215-1-2-2021 pdf Terrestrial photovoltaic (PV) modules – Design qualification and type approval – Part 1-2: Special requirements for testing of thin-film Cadmium Telluride (CdTe) based photovoltaic (PV) modules

11.3 Insulation test (MQT 03) This test of IEC 61215-2:2021 is applicable without modifications. 11.4 Measurement of temperature coefficients (MQT 04) This test of IEC 61215-2:2021 is applicable without modifications. 11.5 Placeholder section, formerly NMOT This subclause of IEC 61215-2:2021 does not require technology-specific modifications. 11.6 Performance at STC (MQT 06.1) This test of IEC 61215-2:2021 is applicable without modifications. 11.7 Performance at low irradiance (MQT 07) This test of IEC 61215-2:2021 is applicable without modifications. 11.8 Outdoor exposure test (MQT 08) This test of IEC 61215-2:2021 is applicable without modifications.
11.19.4 Initial stabilization (MQT 19.1) Initial stabilization is performed on all modules. To fulfil MQT 19 requirements using light exposure, a minimum of two intervals each of at least 20 kWh/m 2 are required. After this preconditioning all of the test modules shall be measured for STC power (MQT 06.1 of IEC 61215-2:2021). If stabilization is performed outdoors, in general no module temperature limits apply. The outdoor stabilization shall be proven at least with one module using the indoor method following the validation procedure from MQT 19 of IEC 61215-2:2021. The minimum and maximum module temperatures observed during outdoor light exposure stabilization verification while the irradiance level is above 500 W/m 2 shall be the minimum and maximum allowable module temperatures for all modules. If the module temperature falls outside of these limits, the new module temperature range has to be re-verified. Output power determination shall be performed after a minimum cooling time of 30 min and maximum 60 min. A validated alternative procedure can be used in accordance to MQT 19 of IEC 61215-2:2021. 11.19.5 Final stabilization (MQT 19.2) Final stabilization is performed on all modules after the test sequences to prove fulfilment of gate No. 2 requirement of IEC 61215-1:2021. To fulfil MQT 19 requirements using light exposure, at least two intervals of at least 20 kWh/m 2 each are required. If stabilization is performed outdoors, in general no module temperature limits apply. The outdoor stabilization shall be proven at least with one module using the indoor method following MQT 19 of IEC 61215-2:2021. The minimum and maximum module temperatures observed during outdoor light exposure stabilization verification while the irradiance level is above 500 W/m 2 shall be the minimum and maximum allowable module temperatures for all modules. If the module temperature falls outside of these limits, the new module temperature range has to be re-verified.
