Overview

About This System

At an international airport in the West Midlands, near Birmingham, our team delivered the design, manufacture and installation of the ground-mounted solar mounting system for this 6.9 MW solar project. We supplied our HTR System 4.1 – 4-in-Landscape mounting system with driven pile foundations, engineered to meet the project's specific site requirements.

The site presented a number of engineering and installation challenges. We installed 578 solar tables across more than 220 rows on both sides of a separation bund extending approximately 1.2 miles in each direction. Our mounting system had to work with the changing ground profile, where slopes varied between approximately 15° and 20° in two directions. 

Our team designed the structure to suit these variable slopes while maintaining a consistent 23° solar table angle, helping the project meet the required aircraft glint and glare considerations.

Working alongside a live runway and taxiway added further complexity, with the project delivered in accordance with applicable Civil Aviation Authority (CAA) requirements and conditions. Close coordination between our team, our customer, the airport operator and the CAA was essential throughout the project.

The project demonstrates how we can adapt our solar mounting systems, structural engineering and installation approach to suit challenging site conditions while keeping the system practical to manufacture, install and deliver.

The Site

Key Engineering Challenges

  • Complex sloping ground – The solar mounting system had to accommodate bund slopes varying between approximately 15° and 20° in two different directions. 

  • Maintaining the required table angle – Despite the changing ground profile, we needed to maintain a consistent 23° solar table angle to address aircraft glint and glare requirements. 

  • Long and challenging installation area – Our team installed 578 tables across more than 220 rows, positioned on both sides of a separation bund extending approximately 1.2 miles in each direction. 

  • Working alongside an operational airport – The project was delivered next to a live runway and taxiway, requiring us to work within applicable CAA requirements and conditions. 

  • Challenging site conditions during installation – Weather conditions added further difficulty, particularly when our installation team was working on the inclined sections of the bund.
