NSRDB Data Downloads
Freely available downloads of The National Solar Radiation Database.
The National Solar Radiation Database (NSRDB) is a serially complete collection of satellite-derived measurements of solar radiation—including global horizontal irradiance (GHI), direct normal irradiance (DNI), and diffuse horizontal irradiance (DHI)—and other meteorological data. This dataset has been collected to accurately represent long-term solar radiation information at various temporal and spatial scales. The data are publicly available at no cost to users. The API provides easy access for downloading. Other options and details are available here

Spectral Data On-demand (/api/nsrdb_api/solar/spectral_ondemand_download)
The spectral on-demand data service provides solar irradiances on inclined PV panels for 2002 narrow-wavelength bands from 0.28 to 4.0 µm. Based on users’ selection of location, time period, and PV system (fixed or one-axis PV system), a dedicated high-performance server located at NREL computes the spectral data in real time using the Fast All-sky Radiation Model for Solar applications with Narrowband Irradiances on Tilted surfaces (FARMS-NIT) and broadband and ancillary data served by the NSRDB. FARMS-NIT is an innovative radiative transfer model developed at NREL to efficiently and simultaneously calculate the spatial distribution of solar energy (radiances) in narrow-wavelength bands which are integrated over inclined PV panels to infer the plane-of-array (POA) irradiances.
