IEC 60904-3:2019 describes basic measurement principles for determining the electrical output of PV devices. The principles given in this document are designed to relate the performance rating of PV devices to a common reference terrestrial solar spectral irradiance distribution. The reference terrestrial solar spectral irradiance distribution is given in this document in order to classify solar simulators according to the spectral performance requirements contained in IEC 60904-9. The principles contained in this standard cover testing in both natural and simulated sunlight. This new edition includes the following significant technical changes with respect to the previous edition: a) all spectral data were recalculated due to some minor calculation and rounding errors in the third edition; the global spectral irradiance returned to exactly the data of the second edition; b) the angular distribution of the irradiance was clarified.
