Marne Barracks, North Yorkshire

photon energy has installed 267.33kWp of solar pv at marne barracks, north yorkshire for lorne stewart.

Photon Energy won the tender from mechanical and electrical contractor, Lorne Stewart, to install 267.33kWp of solar PV at the new £29 million Marne Barracks development in Richmond, Yorkshire, built by Caledonian.

Defence Estates who commissioned the new building, had a requirement for it to be highly energy efficient and producing a considerable quantity of renewable energy.

 Over 1,000 Trina Solar modules were mounted on two separate Kalzip standing seam roof areas. The PV system will consist of a total of 800 x 270Wp PV modules to be installed on the roofs of buildings B432 and B8 providing a total energy output of 224,730kWh/year.

The Marne Barracks development was a £29 million build project undertaken by Caledonian, a specialist in modular construction who partially built the campus-style buildings off-site. The accommodation was comprised of 10, three story buildings that were completed in 25 weeks, a far quicker time than a traditional building project.

This new accommodation supplied by Defence Estates was required to meet high standards of energy efficiency and this was achieved by incorporating insulated metal cladding as well as mounting the sizeable solar PV array.

Abu Luswata, Senior Engineer of Photon Energy said: 

“This was an interesting project for Photon Energy to get involved in. The brown roof and pebbled areas created obstacles that had to be worked around and in addition, we had to coordinate with many other tradesman working in the roof areas. Nevertheless this was a successful installation.”

Jerry Denny, Senior Project Manager at Lorne Stewart said:

“Photon Energy successfully rose to the challenge of designing the solar PV arrays and installing them on the limited roof space. The installation was carried out to a high standard across the development.”
