The National Solar Radiation Database (NSRDB) is the most accessed, public database of solar irradiance and associated weather parameters for use in solar energy projects. The NSRDB underpins a large range of activities that take place within DOE Solar Energy Technology Office (SETO) that facilitate high-penetration of solar technologies by providing easy access to high-quality, foundational data essential for innovative product development and downstream modeling. The NSRDB data is currently available for the contiguous United States, Central America, and South Asia. The NSRDB contains 4km x 4km on half-hourly spatial and temporal resolution, respectively from 1998-2017. For 2018, the resolution will increase to 2km x 2km and on 5 minutes interval. The Physical Solar Model (PSM) underpins the datasets is a unique physics-based model that has been developed at NREL and has opened the door to the use of next-generation satellite datasets for solar resource assessment and forecasting.
NSRDB data are used to improve the accuracy of grid integration studies, facilitate energy and economic modeling using System Advisor Model (SAM), PlantPredict and PVsyst as well as support the solar industry by reducing costs of solar project development through provision of long-term accurate historical solar datasets. The poster will demonstrate 1) the evolution of the NSRDB from sparse data to high resolution dataset; 2) on demand services and their application 3) summary products such Typical Meteorological Year (TMY) dataset and 4) wider user availability through cloud services.
