Airports are among the largest consumers of energy due to their extensive operations, including lighting, heating, cooling, and powering various electrical systems. “The aviation industry is responsible for roughly 2% of the world’s carbon emissions, of which 5% come from airports.” Source. As the aviation industry continues to grow, the environmental footprint of airports also increases, making the need for renewable energy solutions more pressing than ever.
In response to global climate change and increased regulatory pressures, many airports are setting ambitious sustainability targets. Renewable energy, particularly solar power, presents a viable solution to help airports reduce their carbon emissions and achieve their environmental goals.
Traditional solar installations often pose significant challenges for airports. One primary concern is the weight of conventional solar panels, which many airport rooftops, such as hangars and terminals, are not structurally equipped to support, as is the case with an estimated 45% of commercial rooftops in the UK.

Additionally, the architectural design of airport buildings, which often include curved surfaces and unique structures makes the installation of rigid solar panels difficult. Often, it is a requirement for panels to be installed without rooftop penetration. Safety concerns, such as glint and glare which could interfere with air traffic, also pose significant hurdles.
Innovative lightweight solar solutions are transforming the way airports harness renewable energy. This cutting-edge technology provides a practical and efficient alternative to traditional solar panels, overcoming many of the challenges associated with weight and structural compatibility.
Lightweight solar panels offer competitive performance. Lightweight panels can be fitted to a variety of roof surfaces with minimal structural impact and without penetrating the roof itself. Furthermore, these panels tend to have lower glare characteristics of up to 97% than traditional glass panels, making them ideal for aviation environments where safety is paramount.
Farnborough Airport in Hampshire, UK, serves as a leading example of how lightweight solar technology can be successfully implemented in aviation. Partnering with Solivus, a pioneer in lightweight solar installations, Farnborough Airport undertook a £2m solar project, contributing to their goals of achieving net zero emissions by 2030. Source.
Due to operational and environmental restrictions, ground-mounted solar installations were not feasible, making rooftop solar the only viable option. However, the iconic architectural curves of the airport buildings and the inability of rooftops to support traditional solar panels posed significant challenges.
Solivus' lightweight solar system provided an effective solution. Over 4,000 lightweight solar panels were installed across various airport structures, including hangars, the terminal, control tower, and hotel. The completed installation is set to power up to 25% of the airport's annual electricity needs, supports the charging of electric vehicles, and contributes significantly to the airport's carbon neutrality goals.
The success of Farnborough Airport's solar transformation highlights the potential for other airports to follow suit. By embracing lightweight solar technology, airports can significantly reduce their carbon footprints to meet Net Zero goals, lower energy costs, and demonstrate leadership in sustainability.
Governments and regulatory bodies are increasingly supporting the deployment of rooftop solar on commercial properties, with policies such as the Solar Action Plan and the London Growth Plan, further incentivizing airports to adopt these solutions. As technology continues to advance, the feasibility and benefits of lightweight solar installations will only grow, making them an essential component of the aviation industry's journey towards a sustainable future.
