| Abstract: | The present paper describes the implementation of a method to perform measurements at different irradiance levels on PV devices in accordance with the standard IEC-61853-1: “Irradiance and temperature performance measurements and Power Rating”. Previously we have reported Power Rating measurements on PV devices of different technologies using uncalibrated mesh filters. These were not strongly attenuating and hence needed to be stacked to arrive to irradiance levels as low as 100 W/m2 both in solar simulators and in natural sunlight. Due to spatial non-uniformities at low irradiance levels poor results were obtained, especially for thin film modules. New high quality commercially available meshes have been obtained and it is shown that they may be used to arrive at low irradiance levels with excellent results for full-size PV modules. |
