Climatological maps of solar energy in Greece

The Hellenic Network of Solar Energy (HNSE) has been developed to support applications of solar energy with the combined use of ground-based measurements, satellite images and theoretical calculations with radiative transfer and weather forecasting models.

In this frame, HNSE provides climatological maps of global horizontal and direct normal irradiance (GHI and DNI respectively) in Greece for the period 2002-2012. Satellite-derived information of cloudiness, aerosol information and model calculations of solar irradiance are used in synergy to provide maps of the available solar power at a resolution of 0.05°x0.05°.


The maps are free for public use, their reproduction is authorised provided the source is acknowledged: http://atmosphere-upatras.gr/solarmaps, Hellenic Network of Solar Energy, 2002-2012.
