Configuration Options

NRG Systems’ SRA System is a complete and integrated measurement solution for the prospecting and formal resource assessment of utility-scale photovoltaic projects. All relevant meteorological conditions are captured, including solar irradiance, wind speed and direction, ambient temperature, relative humidity, barometric pressure, and precipitation.

Each SRA System is made up of three components and includes everything necessary for your measurement campaign: tower, logger, and sensors—pre-configured and ready to ship within days of order placement. This standardized hardware foundation supports a variety of different sensor configurations to meet your measurement needs.

  • NRG’s lean manufacturing and global supply chain capabilities enable professional, repeatable measurement results across your fleet of projects
  • Integrated system approach translates to simplified procurement, shorter lead times, and more efficient installations and O&M services
  • Backed by global Technical Services Partner Network
  • Technically sophisticated yet easy to use, this industry-standard system automatically delivers accurate data via cellular or satellite communications
  • The SRA System can easily be re-used from one campaign to the next OR transition from pre- to post-construction solar resource monitoring with just a few component updates

"The best thing in the field is predictability, and I think that NRG Systems is really shining when it comes to that. With NRG's SRA System, I know exactly what I’m going to get, I know exactly how the equipment is going to work together, and I don’t feel like I have to be prepared for every possible sequence of events."
