Access data and analysis services that provide access to solar resource data and NREL models.
PVDAQ is a comprehensive mapping tool to help industry and government planners study solar array efficiency. The PVDAQ website provides a public interface to some of the PV performance data contributed to NREL. This collection provides documentation of the same api that the website utilizes to display its data.
NREL's PVWatts calculates the energy production and cost savings of grid-connected photovoltaic (PV) energy systems. This service estimates the performance of hypothetical residential and small commercial PV installations.
Provides monthly average and annual average daily total direct normal solar resource values (watt-hours/m2/day) at a given location.
