This report presents results of the solar resource assessment and mapping activity undertaken by The World Bank in Maldives, as a part of a broader technical assistance project covering biomass, solar and wind mapping funded by the Energy Sector Management Assistance Program (ESMAP). The data used in this report is based on the Solargis model. The uncertainty of the solar resource data has been reduced by the regional model adaptation based on the ground measurements collected at four solar meteorological stations across Maldives, commissioned by The World Bank during the years 2015 to 2018 under the same activity. The ground-based solar resource measurements have been supplied by Suntrace GmbH, Germany. The measurement campaign has been technically supported by Renewable Energy Maldives company, based in Maldives. The report has two objectives: to explain the methodologies and outcomes of the solar resource and photovoltaic power potential assessment, based on the combined use of models and measured data. The report documents the uncertainty of solar and meteorological data as key inputs in the technical and financial evaluation of solar energy systems; and to improve the awareness and knowledge of resources for solar energy technologies by producing a comprehensive countrywide dataset and maps based on the accuracy-enhanced models. The report evaluates key solar climate features, and the geographic and time variability of solar power potential in the country.
