Together with the Physikalische Technische Bundesanstalt (PTB) 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 aim of the project is to develop guidelines, and to give an overview, of the measurement techniques and infrastructures in the new photovoltaic (PV) technology in order, among other things, to reduce the costs of this on the energy market. The project description states: " 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 all 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.

[Translate to Englisch:] The goal of the project is the development of a new innovative urban climat model that is able to simulate the microclimate in densely-populated cities like Berlin with a spatial resolution of less than 10 m. The model will be developed as a user-friendly tool, which can be applied by both scientists and urban planners.
