BBC Wales toasts new broadcast HQ with 120kW rooftop solar array

BBC Wales toasts new broadcast HQ with 120kW rooftop solar array

Leading renewable energy developer and consultancy, Dulas, has completed the installation of a 120kWp rooftop solar array at BBC Wales’ new broadcast centre utilising a new inverter technology in the development. The project builds on Dulas’ strong track record in the delivery of rooftop-mounted PV arrays, which has seen it deliver over 11MW of projects across the UK.

As part of their commitment to the new premises being built to BREEAM standards, the BBC sought to incorporate the installation of solar panels at the 150,000 sq. ft. facility. Following a competitive bidding process, Dulas was commissioned to carry out the design and installation by mechanical and electrical firm Evans Electrical.

However, configuration of the solar array was made more difficult by the available roof space for PV panels, which was split across several distinct and separate areas, presenting a number of technical challenges. With significant experience in bespoke solar array installation – particularly for the new build sector – Dulas’ expertise in PV array design resulted in a complex but efficient layout that maximised energy generation from the available roof-space.

Working over the course of four weeks, Dulas’ team of solar engineers completed installation of the panels as well as laying the on-roof cables. Two engineers then returned to the site in January to finalise the necessary electrical work, including the installation of inverters, meters and isolators. Dulas carried out a range of final tests of the array prior to the scheme’s commissioning.

Significantly, Dulas oversaw the installation of a brand new type of inverter, designed to provide maximum efficiency within a particularly compact unit. These are some of the first of their type to be installed in the UK.

“Rooftop solar is becoming an increasingly common and financially attractive option for both public and private institutions looking to reduce energy costs and meet high sustainability and building standards,” said Claire Toland, Project Manager for UK solar at Dulas.

“Our team has a wealth of experience in the planning and delivery of customised solar PV arrays like that at the BBC Wales broadcast centre, and were able to design and implement a scheme that will deliver real value for this flagship new build.”

“Dulas’ reputation for rooftop solar is second to none within the industry, and we worked closely with their team of specialists to incorporate the new inverter and deliver a scheme that meets the highest mark of BREEAM standards,” added Matt Davies, Project Engineer at Evans Electrical.
