Global Solar Atlas – online platform for a preliminary solar energy assessment


Global Solar Atlas – online platform for a preliminary solar energy assessment, Worldwide

The objective of Global Solar Atlas is to provide immediate access to reliable information for preliminary solar energy assessments for anywhere in the world. The online platform is a gateway to global and regional solar resource data, primarily targeting decision makers in developing countries (state and regional governments, experts on electricity production, transfer and consumption, and RE insiders). Its important impact is also recognized in the research community and educational sector.

The Atlas features basic data from the Solargis database, with some location information from the portal. Ancillary data are provided from other public sources.

Free access to the data is provided via an online application. Data are presented as numeric values and interactive maps. An extensive download section has been built, providing print-ready map files, GIS data and other products. All resources are provided as a global package or separately for 146 non-OECD countries and 6 regions. A rich knowledge base is available, especially for newcomers to the solar energy sector.

Global Solar Atlas was published by the World Bank Group, funded by ESMAP, and prepared by Solargis.
