Background Solar Convergence occurs when multiple reflective glass panels simultaneously reflect the sun to one point with an intensity greater than that of direct sunlight. In July 2017 the City [...]

Yes they do. Strong (Photovoltaic) PV glare may be caused by reflections from a low sun. Whilst panels are designed to efficiently absorb direct and diffuse light they are often [...]

Requirements for glare intensity modelling Glare intensity modelling is a common planning requirement for solar photovoltaic developments. Increasingly, it is becoming a requirement for other development types as well, for [...]

In this article we consider forms of radar interference; causes; mitigation options and management for various types of radar. Radar Interference Principles Radars transmit and receive radio signals – analysing [...]

Overview Pager Power recently conducted a consultation process with Network Rail to better understand their assessment requirements when it comes to glint, glare and their operations. The following article presents [...]

Introduction Wind turbine shadow flicker is the effect caused when a spinning turbine rotor causes brightness levels to vary within an affected room (although the precise definition can depend on [...]

Overview NATS are a key UK aviation stakeholder and their main role is to aid the safe navigation of en-route aircraft, and in some instances, with the safeguarding of civil [...]

SGHAT (Solar Glare Hazard Analysis Tool) is no longer freely available – as of November 2017. SGHAT is used for predicting solar panel glare, also referred to as PV glare, [...]

Wind farms and radar Wind farm developments around the world face objections from radar operators. This is because large wind turbines can interact with radar signals, causing interference. Figure 1: [...]

Previous articles: Radar concerns have rendered two turbines motionless Aveillant technology to mitigate the effects of two wind turbines at East Midlands Airport Overview Three years in the making, the [...]
