    • NIST Campus Photovoltaic (PV) Arrays and Weather Station Data Sets

    Metadata Updated: September 30, 2025

    One-minute averaged values and one-second instantaneous values for 2015 through 2018 for three grid-connected photovoltaic arrays on the NIST campus in Gaithersburg, Maryland USA. The arrays are built from monocrystalline silicon modules and range from 73 kW to 217 kW. Each array has a different tilt, orientation, and configuration. Irradiance, temperature, wind, and electrical measurements are recorded at each array. One-minute average data and one-second instantaneous data from a nearby weather station and images of the sky and arrays at one-hour and five-minute intervals are also included.
