Laboratory: Sandia National Laboratories

Technology: Solar Glare Hazard Analysis Tool (SGHAT) version 3.0

Opportunity: Sandia’s SGHAT v. 3.0 technology has completed all of its technology readiness stages and is available for collaborative partners.

Details: Winner of a 2013 R&D 100 Award, the SGHAT technology is a web-based tool and methodology to evaluate glint and glare hazards that are associated with solar energy installations. The 3.0 version of SGHAT has been updated to automatically select the optimal tilt and orientation configurations of solar installations that can reduce glare and maximize overall energy production.

Benefits: Given the increase in solar energy systems being installed across the country, SGHAT v. 3.0 has the ability to positively impact the hazards that can occur from radiation of solar reflection from solar power plants, as well as reduce the distractions that can occur for pilots, air traffic controllers, motorists, and others by quantifying glare intensity, and when and where glare will occur throughout the year, among other benefits.

Potential Applications: SGHAT v. 3.0 can be applied in the following areas:

  • Glint and glare sight hazard analysis for future and currently established solar installations
  • Determine optimal solar installation designs to maximize energy production and reduce glare.
