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
