Glint and Glare Studies for Commercial and Industrial Solar Sites

February 16, 2016

What is Solar Glint and Glare?

Glint is also known as a specular reflection, produced as a direct reflection of the sun in the surface of the PV solar panel. This is the potential source of the visual issues regarding  viewer distraction. Glare is a continuous source of brightness, relative to diffused lighting. This is not a direct reflection of the sun, but rather a reflection of the bright sky around the sun. Glare is significantly less intense than glint but can be more sustained over time.

The issue of glint and glare, as it pertains to photovoltaic systems, has been studied by the Federal Aviation Administration (FAA), the US Air Force and Sandia National Labs extensively. Sandia National Labs has developed the Solar Glare Hazard Analysis Tool (SGHAT), which has been used to run simulations for different observation points around a proposed photovoltaic solar array.

The most important aspect of the glare analysis study for commercial and utility solar projects is to ensure that the glare does not cause travel hazards and impair the quality of life of the surrounding residences or buildings. Some locations of solar arrays or any glass surface for that matter will create visual impacts on the surrounding environment. A glint and glare study will be important to determine the amount of time and intensity that glint and glare occurs.When is a Solar Array Glint and Glare study important?

A solar array glint and glare study is performed by studying the spectral reflectivity of the solar array from several surrounding points from the solar array. The glint and glare hazard is studied in great detail to look at the intensity of glint or glare from various perspectives.

Solar arrays are designed to absorb light and produce electricity. The anti-reflective coatings or treatments on glass and solar cells significantly reduce glint and glare to increase a solar module’s light absorption properties. However, as with any glass or metal object, light reflection can be created. Blue Oak Energy performs glint and glare studies for commercial solar, industrial solar and utility scale solar generation facilities. It is important to properly plan commercial and industrial solar projects so no surprises are encountered post-construction. If you’re in need of a glint and glare study for planning your solar development or solar array, we’re here to help!
