Glint & Glare: Aviation and Solar PV

Managing the effect of Glint & Glare from Solar PV farms on aviation is crucial for ensuring safe airfield operations.

Solar photovoltaic (PV) farms, with their expansive arrays of solar panels, are increasingly prominent in our landscapes as we transition to renewable energy sources.

While these farms are lauded for their environmental benefits, they pose challenges for aviation due to glint & glare effects.

Understanding Glint & Glare

Glint refers to the sunlight that reflects off the surface of solar panels. Bright spots can be created causing visual distraction for pilots.

Glare, on the other hand, occurs when the intensity of reflected sunlight exceeds that of the surrounding environment. This can potentially cause temporary blindness or visual discomfort for pilots.

These effects are particularly critical for pilots flying at lower altitudes during take-off or landing, as they can impede visibility and navigation.

Mitigation Strategies for Glint & Glare

To mitigate these challenges, careful planning and placement of solar PV farms are essential.

Factors such as the orientation of the panels, their tilt angle, and the proximity of flight paths must be considered to minimize glint and glare effects on aviation routes.

Technological solutions, such as anti-reflective coatings on solar panels and advanced monitoring systems to predict and manage glare, can enhance aviation safety around solar PV installations.

Our Expertise in Managing Glint & Glare

We offer expert advice to developers and airfield stakeholders regarding the effects of solar PV farms on aviation, focusing on glint and glare.

Our advanced analysis software helps assess the risks and propose mitigation strategies for glint and glare effects on approaching aircraft.

Case Study: Helicopter Approach Path Assessment

In a recent case study, we used our advanced analysis techniques to assess 360-degree approach path vectors for helicopters across a solar PV farm on behalf of airfield stakeholders.
