Download the direct normal irradiance (DNI) maps individually below, or download all the DNI maps at once. Note: The publication dates listed below don't necessarily reflect the publication dates of the data therein.
View an interactive map or download geospatial data on solar photovoltaic supply curves. These solar maps provide average daily total solar resource information on grid cells.
NREL has provided solar resource data for the United States through the NRSDB for more than 25 years. The NSRDB contains not only data for the United States, but also for a growing list of countries in different parts of the world. Learn about the Typical Meterological Year (TMY) data type used in the NSRDB.
A serially complete collection of hourly and half-hourly values of meteorological data and the three most common measurements of solar radiation: global horizontal, direct normal and diffuse horizontal irradiance. It covers the United States and a growing subset of international locations.
GIS data for India's direct normal irradiance (DNI) and global horizontal irradiance. Provides 10-kilometer (km) solar resource maps and data for India.
The development of a serially complete NSRDB with consistent spatial and temporal mapping requires several steps for organizing and refining input data prior to the computation by FARMS: regridding, temporal interpolation, time shifting, and gap filling.
NREL develops and maintains data sets, maps, models, and tools to analyze and overcome technical barriers to accelerate concentrating solar power (CSP) technologies. NREL maintains the Solar Power and Chemical Energy Systems (SolarPACES) worldwide database of CSP projects across 19 member countries.
