Power Rating of Photovoltaic Modules Including Validation of Procedures to Implement IEC 61853-1 on Solar Simulators and under Natural Sunlight

This paper describes the implementation of standard IEC 61853 - Part 1 [1] at the European Solar Test Installation (ESTI). The purpose of this work is to assess the reproducibility of the power matrix measurements obtained by the three methods specified in that standard, namely: under natural sunlight using a tracking system; under natural sunlight without tracker; using a Large Area Pulsed Solar Simulator of Class AAA. Three module technologies (poly-Si, CdTe and CIS) were characterized according to the IEC standard. The present work also includes a procedure based on un-calibrated mesh filters compared to other techniques available at ESTI to reduce the irradiance intensity using indoor apparatus. The advantage is that mesh filters can be mounted outdoor as well as indoor allowing direct comparison of measurement results. All three methods as implemented at ESTI agree well for irradiances at and above 400 W/m2. With the additional use of a calibrated self-reference variant, applied to solve issues of uniformity and spectral changes [2], good agreement was found for all irradiances for all three module technologies studied. These aspects have been studied to improve the mesh filtering procedure and to evaluate its introduction in the ISO 17025 Quality System of ESTI.
