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 farms 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 projects 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 SymphoniePLUS3 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

SENSORS
The NRG SRA System comes in four different sensor configurations, each built around a pair of pyranometers that provide redundant measurements of Global Horizontal Irradiance (GHI). In the standard configuration both pyranometers are secured to a horizontal mounting platform located on top of the tower. Adjustable plane-of-array (POA) booms that enable you to gather data at the angle of your prospective PV arrays are also available asan optional feature.Each pyranometer model integrates seamlessly with theSymphoniePRO Data Loggervia a Signal Conditioning Module (P-SCM).
OurSecondary Standard (SS) SRA Systemconfiguration is recommended for finance-grade resource assessment campaigns and solar monitoring applications when measurement accuracy is the top priority. This configuration includes twoHukseflux SR20 Pyranometers that deliver accurate solar radiation measurements traceable to the highest category in the ISO 9060 standard: secondary standard.
OurFirst Class (FC) SRA Systemconfiguration is recommended for finance-grade resource assessment campaigns. This configuration includes twoHukseflux SR11 Pyranometers that deliver accurate solar radiation measurements traceable to ISO 9060 first class criteria.
OurSecond Class (SC) SRA Systemconfiguration is recommended for resource assessment campaigns. This configuration includes twoHukseflux LP02 Pyranometers that deliver accurate solar radiation measurements traceable to ISO 9060 second class criteria.
OurLi-Cor Photodiode SRA Systemconfiguration is recommended for early stage solar resource prospecting. This configuration includes twoLi-Cor LI-200R photodiode pyranometersthat deliver solar radiation measurements via a small current signal.
Note: The NRG SRA System can accommodate all industry-standard thermopile pyranometers in place of one of our pre-configured sensor kits, and these kits can be easily customized to meet your projects needs. Customers looking to collect multiple radiation components (e.g., diffuse radiation in addition to GHI) can optionally add theSPN1 Sunshine Pyranometerfrom Delta-T to their system. Pleasecontact our sales teamfor pricing on the SPN1 or to discuss other sensor substitutions.
