This dataset provides basic data for assessing solar potential on a per-building basis in the canton of Geneva, Switzerland. It includes the distribution of roof surfaces by irradiation range and the monthly distribution of solar irradiation. It is intended as a secondary product supporting more detailed analyses, such as estimating the solar energy production potential of individual rooftops. The dataset is maintained by the Système d'information du territoire genevois (Geneva territorial information system), the cantonal authority responsible for geographic and land-related data in Geneva.”Produit secondaire Cette couche contient les données de base permettant d'évaluer le potentiel solaire par bâtiment. Ces données portent notamment sur la répartition des surfaces de toitures par tranche d'irradiation et la répartition mensuelle de l'irradiation solaire. Par exemple, si l'usager sou…
