This database contains parameters gathered after an assessment of the technological potential for development of floating solar photovoltaic (PV) projects on existing hydropower dams and other reservoirs, starting with a pilot in FY18 focused on West Africa and India. The database is primarily based on the information provided by FAO Aquastat Database (http://www.fao.org/nr/water/aquastat/sets/index.stm#dams) and on the data gathered from World Bank hydro projects. The database will be included in the Global Solar Atlas (http://globalsolaratlas.info/) where they will be directly linked to the solar resource maps. The purpose of the resulting Floating Solar Atlas is to enable potential developers or stakeholders to quickly navigate to the site of interest and obtain information about the potential for development of a floating solar PV project. Following the FY18 pilot, the work is likely to be scaled up to provide global coverage.
