| Popis: | 33rd European Photovoltaic Solar Energy Conference and Exhibition; 1588-1592 In this paper, we have proposed and realized an inexpensive and accurate sensor to measure the solar irradiance, the sensor is based in a small calibrated PV module. The method of measure consists in acquiring the short circuit current ISC which is proportional to the incident solar irradiance by measuring the voltage across a precision shunt resistor connected to the reference module, then the final value is corrected according to ambient temperature to take into account the variation of the short circuit current ISC with cell temperature. The reference module was calibrated following the recommendations stated in the international standards IEC 60904-2 and IEC 60906-4, it was used to measure in-plane and horizontal irradiance for more than one year, acquired data were compared with data from commercial and highly accurate sensors, and the results have shown that the accuracy was better than 3%. |
