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

One-minute averaged values for 2015 and 2016 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 from a nearby weather station and images of the sky and arrays at one-hour intervals are also included. Higher frequency one-second data and images at five-minute intervals are available upon request.
