THERMAL CYCLING TEST (MQT 11) – TCT | DIN EN 61215-2:2017-08 Purpose 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. Test device Climate chamber with: v Automatic temperature control and air circulation v Function for preventing condensation on the PV module v Integrated module fastening rails for improved air circulation v Temperature gauge v Continuous electricity supply Process v Attachment and inclusion of PV modules at room temperature v Temperature influence of -40°C to +80°C with power supply to the PV modules v Total cycle duration: 6 hours v Number of cycles: 200 v At least 1 hour recovery time at room temperature Tests before and after v Visual inspection (DIN EN 61215/10.1) the inspection v Measurement to determine the maximum output with electroluminescence imaging (DIN EN 61215/10.2) v 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 -40 Max. temperature fluctuation per hour ≤ 100°C Repetition up to defined number of cycles At least 10 minutes at -40°C Longest cycle time 1 2 3 4 5 6 7 8 Time (h) IBC SOLAR AG | Am Hochgericht 10, 96231 Bad Staffelstein, Germany | Phone +49 (0)9573-92 24 0 | firstname.lastname@example.org | www.ibc-solar.com As of: 10.2018 | 9001400101
