A study led by the University of Girona (UdG) indicates that the highest radiation values in Catalonia are recorded in the Lleida Plain and the southern parts of the country. Conversely, the lowest values are found in areas such as the Eastern Pyrenees and along an axis stretching between Ripollès and Baix Empordà, according to the researchers.
Scientists attribute this pattern to geographical and climatic factors. The atlas, developed by the UdG, shows Catalonia has a high solar resource compared to other European regions. The average radiation ranges between 13.5 and 16.5 MJ per square metre, with a 20% variation between the highest and lowest radiation zones.
Updating Radiation Data
This latest edition of the atlas, presented on Friday, updates a previous version published in 2000. The updated data provides a clearer picture of solar radiation distribution across Catalonia, which could be useful for renewable energy planning and other environmental studies. The findings highlight specific areas with significant solar potential.
