Three regions have more than 1.2 GW of installed solar capacity: Nouvelle-Aquitaine, Occitanie and Provence-Alpes-Côte d’Azur. These regions account for more than 62% of installed solar capacity in France, due to their geographic location in the southernmost part of the country, where conditions are favourable for solar power use and development. The Auvergne-Rhône-Alpes region saw the sharpest increase in installed solar capacity during the year (more than 19%).
