Influence of ambient conditions in the power rating of CPV modules

Abstract

The determination of the ideal conditions for making the measurements to power rate a CPV module is a challenge. In general, all the methods proposed are establishing a range of filters for ambient conditions, when power rating a CPV module. In this paper, the influence of different filters in the deviation of the nomimal power rated is presented for 3 different CPV technologies using two different methods to obtain the nominal power (CSTC IEC62670 draft and PVUSA). The objective is to obtain an approach of how accurate the calculations are depending on the ambient conditions filtering. The result is that, using commercially available meteorological instrumentation and simple filters, the deviation of the power rated can be smaller than 2%. © 2012 American Institute of Physics.
