DAMP HEAT

DAMP HEAT TEST (MQT 13) | DIN EN 61215-2:2017-08 Purpose Determining the suitability of PV modules to withstand the long-term penetration of moisture. 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 Process v Attachment and inclusion of PV modules at room temperature v Conducting the test according to IEC 60068-2-78 at +85°C and a relative humidity of 85% v Total cycle duration: 1,000 hours v At least 2 to 4 hours recovery time at room temperature and a relative humidity below 75% 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) Module temperature (°C) Relative humidity +85 85% +25 0 1,000 Time (h) IBC SOLAR AG | Am Hochgericht 10, 96231 Bad Staffelstein, Germany | Phone +49 (0)9573-92 24 0 | info@ibc-solar.com | www.ibc-solar.com 500 As of: 10.2018 | 9001400104

ELECTROLUMINESCENCE OF PV MODULES IEC 82/1062/CD:2016 Explanation When applying an electrical voltage to the PV module, light will be emitted by the materials (EL for short) that is captured by an electroluminescent camera. Purpose Process of taking and editing electroluminescence images of PV modules and obtaining metrics through this in order to be able to assess the quality of the image results. Test device v Camera: Great Eyes GE 2048 2048 FI model v CCD sensor specification: 2048 x 2048 pixel format v Camera specifications: Hermetically sealed vacuum head v Software: Integrated and can be controlled with a PC Freely-selectable current and voltage values Process v The PV module is brought into a darkroom to ensure high-quality images v The image angle to the surface must be observed v The connecting cables (+) (-) are connected correctly to the test object v A foreign light source must not be used v The electrical DC power supply is fed in with a voltage that Isc must reach. In order to ensure identical image quality, the DC power supply that is applied is not changed for the same module types v Test temperature: +20°C to +25°C v A temperature fluctuation of 1°C must not be exceeded during the measurement Electroluminescence image of an intact PV module Electroluminescence image of a faulty PV module IBC SOLAR AG | Am Hochgericht 10, 96231 Bad Staffelstein, Germany | Phone +49 (0)9573-92 24 0 | info@ibc-solar.com | www.ibc-solar.com As of: 10.2018 | 9001400105
