Together with the PTB (Physikalische Technische Bundesanstalt) in Braunschweig and 11 other European cooperation partners, a joint EU project entitled "16ENG02 PV Enerate, Advanced PV Energy Rating" was started in 2017. The project has two main objectives: Firstly, to improve the PV energy rating standards and secondly, to improve the measurement equipment and methodologies to enable precise measurements of the parameters required for the energy rating. Our task in the project is to measure the spectral radiance under different weather and cloud conditions with the AMUDIS (Advanced Multidirectional Spectroradiometer) in three spectral ranges (UV, VIS and IR) and to compare the measurements with the PTB skyscanner. The measurements and the comparison of the two systems will lead to a better understanding of the different sources of uncertainty, which will allow to reduce the measurement uncertainty. Finally, the processed data will be used as input parameters for the improvement of energy yield calculations for an optional alignment of PV modules.
