Online tool available at re.jrc.ec.europa.eu/pvgis.html - PVGIS Ⓒ European Communities, 2000-2020. In this work, hourly data is post-processed into yearly, monthly and daily statistics - and visualized using boxplots. The main focus of PVGIS is photovoltaic solar. Wind statistics are experimental, and have known issues.
