The comparison of outdoor and indoor measurements has always been challenging in PV. In CPV is still more critical because more factors, like meteorological, optical properties, misalignments…, affect to the modules behavior. There is still no standard procedure to perform the power rating of a CPV module, the IEC committee is now working in the creation of a draft of this standard (IEC 62670). In this way, very hard efforts in research are being done to minimize uncertainties and test times to determine the suitable rating procedure to use that represent or capture the actual performance of the different CPV technologies. The main objective of this work is to test the different proposals of procedures for outdoor and indoor measurements, based in the IEC-62670 standard draft. The results are analyzed in order to validate the procedures, looking for the minimal uncertainty in the determination of the power. The main result is that there are characterization procedures that are delivering good results when the technology is well known and the ambient conditions limited during the measurements, if not some non linearity effects could appear in the performance of some CPV modules.
