In 2010, European energy commissioner Günther Oettinger said during an interview that Europe would import hundreds of megawatts of solar electricity from North Africa within five years, well he didn’t just say it. European Commission Joint Research Centre in all these years has been mapping the PV solar electricity potentials in various parts of the earth to facilitate and accelerate solar power generation for countries and the private sector.
PVGIS was developed 10 years ago at the European Commission Joint Research Centre, in Ispra, Italy. The focus of PVGIS has been to do research in solar resource assessment, photovoltaic (PV) performance studies, and the dissemination of knowledge and data about solar radiation and PV performance. The m0st famous outcome of their research is the online PVGIS web application and maps. Here you have a direct link to download the high-resolution map of PV solar Electricity Potentials in Africa.
