PVGIS 5.3

Released on 25 September 2024, now the default version for the web user interface and for API calls

1. Features

PVGIS 5.3 includes the following improvements: 

  • Update and extension of the temporal coverage of current PVGIS solar radiation and meteorological datasets, up to the year 2023.
  • Datasets now include satellite-based SARAH-3 and reanalysis ERA5+Land (our combination of the high resolution ERA5-Land with an interpolated version of ERA5 around the coastlines). 
  • Data availability has been extended to cover 25 km outside the coastline and inside the water areas.
  • PVGIS 5.1 will now be decommissioned (users can to continue to use PVGIS 5.2). 
  • The JRC-SARAH irradiance dataset (predecessor to JRC-SARAH2 and JRC-SARAH3) is no longer available. Likewise the JRC-ERA-Interim dataset has been taken offline. 

The dataset changes from PVGIS5.2 to PVGIS 5.3 are summarized in the following table
