Solar Resource Assesment

Solar Resource Assessment (SRA) refers to the systematic collection of site-specific meteorological data for the purpose of accurately estimating a prospective solar farm’s annual energy production (AEP).

System Features

  • Field-proven, integrated components measure all relevant meteorological conditions including solar radiation, wind speed and direction, temperature, and precipitation
  • Comprehensive reference data can be used to provide an accurate estimate of your solar project’s potential to improve your project risk profile
  • Adjustable plane-of-array (POA) booms allow pyranometers to measure the solar resource at the angle of the prospective PV array
  • Reliable and proven SymphoniePLUS®3 data logger stores up to two years of data on a non-volatile SD Flash memory card
  • Guyed steel tube tower construction
  • Remote data transfer options using NRG Systems iPackGPS communication modules
  • Easy to transport, assemble, install, and redeploy to other locations
