At Intersolar Europe 2018 in Munich, the Institute for Solar Energy Research (ISFH) will present the accredited solar cell calibration laboratory ISFH-CalTeC and the multi-award-winning outdoor fluorescence inspection system for solar modules “FLOIS”.
The ISFH Calibration and Test Centre (ISFH CalTeC) is accredited by the DAkkS (German Accreditation Body) for calibrated measurements of solar cells and concentrates on the measurement of wafer-based silicon solar cells in laboratory and industrial formats. Both the measurements of the current-voltage (I-V) characteristic curve and the differential spectral irradiance sensitivity (DSR) take place on an area of up to 160 × 160 mm². Accreditation by DAkkS confirms the implementation of the requirements of ISO 17025 for the calibration of solar cells in accordance with the requirements of the IEC 60904 standards. In addition, the ISFH CalTeC is also accredited for the testing of spectroradiometers and the calibration of solar radiation sensors.
With the FLOIS inspection system, which can be used largely independent of weather conditions, up to 200 modules per hour can be checked for cell cracks and other faults without rewiring them. Instead of measuring the module directly, changes in the fluorescence image of the encapsulated material that are generated by the diffusion of oxygen into defective solar modules are detected. Since the process leading to the changes in the fluorescence image takes several days and weeks, FLOIS can also distinguish between old and new cell cracks. Especially for insured damage caused by hailstorms, it is thus possible to make a clear allocation between current and previous damage.
Visit us at the Intersolar Europe at our booth 418 in hall A2.
Intersolar Europe takes place at the Munich Trade Fair and is open daily from Wednesday, June 20 to Friday, June 22, 2018, from 9:00-18:00.
