Solar spectra datasets at optimum and vertical installation angles in central Europe (Berlin) during 2020, 2021 and 2022

The datasets provide three year-round worth of solar spectra for the optimum installation angle of 35° and the building-integrated-photovoltaics relevant vertical angle of 90°. The datasets were obtain measuring the spectrally resolved solar spectra in a five minute interval, using two sets of spectrometers which measure different ranges of the solar spectrum. In addition, the merge of these two spectra, related to every specific five minute interval measurement is provided.
The data for each spectrometer and their merge are provided in compressed ZIP archives containing the CSV files related to a complete year of data for 2020, 2021 and 2022, respectively.
