Glint and Glare assessments

Why assess Glint and Glare effects?

Solar PV panels, glass buildings and large metal structures can cause significant solar reflections that can cause a distraction or nuisance.  Airport, rail, highways and planning authorities therefore often require developers provide glint and glare assessments that accurately describe the likely glint and glare impacts of a proposed development.

What are the benefits of a Pager Power Glint and Glare Assessment?

Planning authorities, airports, rail operators and other organisations sometimes require a glint and glare assessment to be provided. Obtaining a glint and glare assessment can therefore be an important step in obtaining planning permission for a development.

Developments close to airports, railways, roads and dwellings can be refused due to predicted glint and glare impacts. Glint and glare assessments can help identify and resolve potential issues early enabling the development process to be de-risked and progressed efficiently.   

What does a Pager Power Glint and Glare Assessment cover?

Overview

Solar Glint and Glare analysis is undertaken to predict the times and dates when direct solar reflections will occur at specific receptor locations. Charts are produced to show these times and dates as well as (sometimes) the specific parts of the development that will cause the reflections.

Analysis is also often undertaken to determine the likely impact of reflections on the eye. Considerations include the intensity of light at the eye’s retina as well as the apparent size of the solar reflection.

Guidance

Pager Power has produced its own glint and glare guidance in consultation with government and solar trade bodies in the United Kingdom and Ireland. United States Federal Aviation Administration guidance is also often taken into account. Pager Power also has in-house software for assessing reflections from single axis-tracker solar schemes.

Aviation

For aviation assessments receptors typically include runway approaches and air traffic control towers. In some cases additional receptor locations include circling aircraft, aircraft on runways, aircraft on taxiways, vehicles on the aerodrome and fire stations.

Rail

For railway assessments receptors typically include track neighbouring the development, signals locations and pedestrian crossings.

Roads and dwellings

For road/highway assessments receptors typically include sections of highway neighbouring the development and dwellings assessments are often undertaken for dwellings within 1 kilometre of the proposed development.

 

Next Steps

If you have a solar or building development that has reflective surfaces in the vicinity of airports, railways, highways or housing please get in touch – we can advise whether a glint and glare assessment may be able to help your development progress.
