This dataset contains the GIS data used in the report, "Global Photovoltaic Power Potential by Country" generated by Solargis (https://solargis.com), with funding provided by the Energy Sector Management Assistance Program (ESMAP). The study summarizes global solar resource and PV power potential on a country and regional basis. Analysis is based on Solargis's high-resolution datasets, and GIS mask layers which are downloadable via the 'resources' tab. A country comparison spreadsheet is also provided as an additional download, which provides indicators of PV power potential for all countries as described in the study. The study provides: • Ranking and comparison of countries and regions according to their PV potential; • Approximate levelized cost of electricity (LCOE) relevant to current PV projects; • Cross-correlation with the socio-economic indicators relevant to PV development.
