    Solar PV & Reflective Building Surfaces Support

    Glint & Glare

    Reflective Experts You Can Count On

    Arthian provides Glint and Glare Assessments to support planning applications for solar PV developments, including solar farms, roof-mounted panels and solar car ports. In addition, Arthian can assess reflective building facades such as glazed surfaces and metal cladding. These assessments identify potential visual hazards to light-sensitive receptors, helping developers meet planning and safeguarding requirements and avoid objections from aviation, transport and residential stakeholders.
     

    We commonly assess impacts on:

     

    • Aviation receptors – airports, aerodromes, helipads, air traffic control
    • Road users – road vehicle drivers on the Strategic Road Network, highways and local roads
    • Rail infrastructure – train drivers, signals and trackside assets
    • Residential dwellings – amenity impact for nearby properties

    Glint & Glare – The Highlights

    What is a Glint & Glare Assessment, why does your business need one, and how can our experts support? We answer all your questions below.

    What Is Glint and Glare?
    When Is a Glint & Glare Assessment Required?
    Our Assessment Approach
    What Is Glint and Glare?

    What Is Glint and Glare?

    Glint and glare are effects caused by sunlight reflecting off surfaces like solar panels:
     

    • Glint – a brief, momentary flash of bright light
    • Glare – a sustained, intense reflection that can cause visual discomfort or distraction


    These reflections can pose safety risks or reduce amenity for receptors such as pilots, drivers, train operators and residents.

    Glint & Glare Assessment

    When Is a Glint & Glare Assessment Required?

    Planning authorities and consultees may request an assessment when:


       

    • Solar PV development or a reflective building facade is proposed near airfields, roads, railways or dwellings
    • There is potential for visual hazard or amenity impact
    • Failure to assess glint and glare can lead to planning refusal or delays in approval.
    Glint & Glare Assessment Approach

    Our Assessment Approach

    Our process includes:
     

    • Receptor identification – aviation, transport, residential
    • Modelling of solar reflections – dates, times, durations
    • Sun path and panel orientation analysis
    • Mitigation strategy design – layout changes, screening, panel angle adjustment
    • Planning-ready reporting – clear, defensible and regulator-aligned

     
    We use specialist modelling tools and GIS-based analysis to quantify risk and recommend mitigation.

    Frequently Asked Questions

    What is a Glint and Glare Assessment?

    It is a technical study that evaluates whether solar reflections from PV panels or reflective building surfaces could affect nearby receptors such as pilots, drivers or residents.

    What is solar glare?

    Solar glare is a continuous reflection of sunlight from a surface that can cause visual discomfort or safety risks.

    Do I need an assessment for roof-mounted panels?

    Sometimes. Arthian are happy to review and advise where a Glint & Glare Modelling Assessment is required.

    Can you help with mitigation?

    Absolutely. We design layout changes, screening and panel adjustments to reduce or eliminate impacts.
