Measurement of reflected solar irradiance is receiving significant attention by industry, military, and government agencies to assess potential impacts of glint and glare from growing numbers of solar power installations around the world. This website contains tools to evaluate solar glare and receiver irradiance.
The Principal Investigator of this work is Dr. Clifford K. Ho (email@example.com).
The Solar Glare Hazard Analysis Tool (SGHAT) analysis functionality is now restricted to military and federal government users only. Additional restrictions for ALL external users may be imposed in 2018 as we migrate to new servers and as tighter cybersecurity policies are enforced at Sandia. The glare tool source code and algorithms are available for licensing from Sandia Laboratories. Interested parties can contact the licensing department.
The following licensed SGHAT applications are available for public use:

This tool determines when and where solar glare can occur throughout the year from a user-specified PV array as viewed from user-prescribed observation points. The potential ocular impact from the observed glare is also determined, along with a prediction of the annual energy production. Configurations can be quickly modified (e.g., tilt, orientation, shape, location) to identify a design that mitigates glare while maximizing energy production.
Meets FAA glare analysis requirements (78 FR 63276).

The Tower Illuminance Model ("TIM") is a real-time interactive concentrating solar field simulation. TIM models a concentrating tower (receiver), heliostat field, and potential reflected glare based on user-specified parameters such as field capacity, tower height and location. TIM provides a navigable 3D interface, allowing the user to “fly” around the field to determine the potential glare hazard from off-target heliostats. Various heliostat aiming strategies are available for specifying how heliostats behave when in standby mode. Strategies include annulus, point-per-group, up-aiming and single-point-focus. Additionally, TIM includes an avian path feature for approximating the irradiance and feather temperature of a bird flying through the field airspace.
