English: Solar resource: DIRECT NORMAL IRRADIATION (DNI) - this map provides a summary of the estimated solar energy available for power generation and other energy applications. It represents the average daily/yearly totals of direct normal irradiation (DNI), covering the period from 1994/1999/2007 (depending on the geographical region) to 2018. The underlying solar resource database is calculated by the Solargis model from atmospheric and satellite data with 10-, 15- and 30-minute time step respectively, and a spatial resolution of 250 m. Further details available from: https://globalsolaratlas.info. DNI is the most important parameter for energy yield calculation and performance assessment of concentrating solar power (CSP) and concentrator solar photovoltaic (CPV) technologies. DNI is also important for the calculation of global irradiation received by tilted or sun-tracking photovoltaic modules. Further details available at: https://globalsolaratlas.info.
The World Bank Group has published this solar resource map using data from the Global Solar Atlas (GSA), to support the scale-up of solar power in our client countries. This work is funded by the Energy Sector Management Assistance Program (ESMAP), a multi-donor trust fund administered by The World Bank and supported by 18 donor partners. It is part of a global ESMAP initiative on Renewable Energy Resource Mapping that covers biomass, hydropower, solar and wind. This map has been prepared by Solargis, under contract to The World Bank, based on a solar resource database that Solargis owns and maintains.
