Carillion has installed a 50kWp solar array at Nationwide Building Society’s headquarters in Swindon. The installation is the first in the UK to utilise Conergy’s SolarFamulus Air mounting system.

The 50kWp system is expected to generate over 45,000kWh of electricity, negating the release of over 20 tonnes of CO2 into the atmosphere a year.

Support services company Carillion, which provides facilities management for Nationwide, selected the mounting system because it is designed specifically for commercial flat-roofs that are unable to support heavy loads. The under-construction uses a vacuum to secure the frame against the roof without the need for screws.

Robert Goss, Managing Director of Conergy UK, said: “The Solar Famulus Air system is not only very practical, but its wave-like design is very attractive in its own right. It’s great to show it off on such a high profile building. At Conergy we believe aesthetics and innovative design will be a big driver for low carbon technology in the coming years.”

Chris Rhodes, Nationwide’s Product and Marketing Director, said: “This is the first time that solar panels have been installed at Nationwide to generate electricity and we are delighted with the result.  The mounting design allows the panels to fit neatly against the profile of our head office building and the energy generated will help the Society to further reduce its carbon emissions and environmental impact.”

Tom Robinson, Carillion’s Chief Sustainability Officer, said: “This is a great example of how we can work in collaboration with our partners to help reduce their energy costs, bring benefits to the environment and local communities and drive the low carbon economy.”
