The measure of all

The measure of all things. South Pole and Sahara. Determining the highest performance DIN EN IEC 61215-2:2022-02 | MQT02 Temperature cycling test DIN EN IEC 61215-2:2022-02 | MQT11 Purpose Determining the highest output of the PV modules before and after environmental impact tests. The defined value is used as the starting point for the incoming goods inspection and processing complaints. Test device BBA sunlight simulator according to the IEC 60904-9 standard B B A Irradiance Homogeneity Spectrum Process • Comparison object is a PV reference module according to IEC 60904-2 that is stored in a darkroom with UV-reduced light and at a constant temperature of +25°C (±2), therefore its photovoltaic parameters are stable • The PV reference module and the test module are mounted in a recording device that is vertical to the radiation direction • The voltage curve is measured according to IEC 60904-1 Standard • Radiation strength: 1,000 W/m² Test parameter • Test temperature: +25°C (±5) • Measurement period: 10 ms • Test period: 2 minutes • Possibility of low-light measurement from 100 W/m² to 1,000 W/m² in increments of 100 Purpose Test device Determining the suitability of PV modules. Thermal mismatches or material fatigue, for example, can be prevented in advance as a result of simulated temperature fluctuations. Climate chamber with: • Automatic temperature control and air circulation • Function for preventing condensation on the PV module • Integrated module fastening rails for improved air circulation • Temperature gauge • Continuous electricity supply Process • Attachment and inclusion of PV modules at room temperature • Temperature influence of -40°C to +80°C with power supply to the PV modules • Total cycle duration: 6 hours • Number of cycles: 200 • At least 1 hour recovery time at room temperature Tests before • Visual inspection (DIN EN 61215/10.1) and after the • Measurement to determine the maximum output with electroluminescence imaging inspection (DIN EN 61215/10.2) • Testing the insulation resistance subject to water submergence (DIN EN 61215/10.15) +85 +80 At least 10 minutes at +85°C Applied current Modul temperatur (°C) +25 Max. temperature fluctuation per hour ≤ 100°C Repetition up to defined number of cycles -40 At least 10 minutes at -40°C Longest cycle time 1 2 3 4 5 6 7 8 Time (h) 4 5
