The first edition of Pager Power’s Solar Photovoltaic (PV) Glint and Glare Guidance was released in the second quarter of 2017. The second edition is currently out for consultation with key stakeholders however edition 2.0 can now be downloaded at the link above[1].

The guidance document was developed to assist the industry by providing a standard methodology for assessing glint and glare for key receptors. The aim was to reduce uncertainty and risk through the planning process by providing a standardised methodology for assessment.

The methodology produced is now routinely accepted by stakeholders in the UK, Ireland and internationally.

Guidance Contents

Developers, planners and stakeholders may be unsure of the assessment requirements when it comes to glint and glare and this can subsequently lead to delays in the planning process. Pager Power is an industry leading specialist in this area having completed over 300 glint and glare assessments. We have used the knowledge gained during this time to produce a guidance document which considers the most common glint and glare concerns. Within the guidance, four separate receptor categories are considered, these are:

  • Dwellings (residential amenity);
  • Roads (safety);
  • Rail (safety);
  • Aviation (safety).

In total there are ten chapters which are titled as follows:

  1. Chapter 1: Overview
  2. Chapter 2: Consultation
  3. Chapter 3: Literature Review
  4. Chapter 4: Modelling Parameter Requirements
  5. Chapter 5: Glint and Glare Impact Significance
  6. Chapter 6: Assessing the Impact upon Surrounding Dwellings
  7. Chapter 7: Assessing the Impact upon Road Users
  8. Chapter 8: Assessing the Impact upon Railway Operations
  9. Chapter 9: Assessing the Impact upon Aviation Operations
  10. Chapter 10: Overall Conclusions

The second edition of the guidance can now be downloaded at the top of the page. If you have any questions, please get in contact.

Definitions: Glint and Glare Terminology

The Solar Photovoltaic Glint and Glare Guidance covers the methodology for assessment of glint and glare however there are many terms used to describe glint and glare assessments – with all having roughly the same meaning. For reference, the main terms which may be used are presented below:

  1. Glint and Glare Assessment
  2. Solar Photovoltaic Glint and Glare Study
  3. Glint and Glare Study
  4. Solar Glare Hazard Analysis
  5. Glint and Glare Analysis
  6. Solar Glare Assessment
  7. Glare and Glint Analysis
  8. Solar Glare Study
  9. Solar Panel Glare Study

At Pager Power we use the terms Glint and Glare Assessment and Solar Photovoltaic Glint and Glare Study.
