Birch Grove

Tim Nicoll from Marley explains: “The development at Birch Grove has transformed previously derelict land into highly attractive and sustainable housing solutions that enhance the locality. The desire to utilise renewable technologies such as solar PV on the roofscape was central to the creation of these stand-out eco homes.”

Following initial discussions with the development team, Marley set out to make the case for the Marley SolarTile®. As a fully integrated solar PV panel, it generates renewable energy while also contributing to a building's aesthetic. Unlike traditional solar panels that are mounted above the roof surface, SolarTile® sits flush with the roof covering, providing both functionality and a streamlined design.

Although the client was worried about the potential for water tightness and achieving the required power output, these concerns were allayed through Marley’s comprehensive roof and fixing specification.

Tim explains: “The site needed to generate around 30 to 40 kilowatts of power, and through our calculations, we established that 110 solar panels across the three property roofs would create enough sustainable energy for the entire development. The ability of Marley SolarTile® to be fully integrated into the roofing system also added to the benefits.”

“We had to think outside of the box”, says Tim, “to create a seamless and high-performing design that combined the Marley SolarTile®, metal sheeting and clay tiles. Our technical team produced a robust roofing and fixing specification, including working around dormers, windows and roof lights.

“This included addressing specific concerns about water tightness between the SolarTile® and the metal sheeting. We were able to demonstrate how both products would work together perfectly, addressing any concerns. I know the client is delighted with the roofing finish and performance of the solar panels.”

Supporting solar panel installation with on-site training

The technical specification and sample services underpinned the planning and pre-build processes. But Marley also invested time and resources into supporting the Marley SolarTile® installation phase.

This included training prior to installation, as well as an on-site visit to provide in-person training. This gave contractors a thorough understanding of the methodology behind the Marley SolarTile® installation – including the easy-to-follow colour coding for all components in the system.

Tim Nicoll says: “As well as the pre-installation training for roofers who had not worked with solar PV before, we also made sure we were present on site as the solar panels were installed on the first roof at the development.”

He continues: “In addition to offering guidance and a reassuring presence, we were able to support with challenges such as marrying the flashing with the edge of the integrated solar panel to produce a watertight seal. We also re-visited the site later in the installation phase to double-check that the fitting standards were being maintained. We were delighted to see that they were.”

Solar panels contributing to an award-winning development

The success of the Birch Grove development has been recognised with the Best House award at the National Building and Construction Awards. The award recognised both the project's striking design and its sustainable ethos, with Marley's SolarTile® playing a key role by delivering energy efficiency to the homes.

Paul Higgs, founder of The Millbank Group, comments: “We are extremely proud of the three stunning eco farmhouses we have developed at Birch Grove. We had a strong sustainability vision for the project. Marley’s technical expertise, and ongoing specification and installation support across the build were invaluable. The integrated Marley SolarTile® panels on the roof not only look good, but they were also easy to install. They’re now delivering the renewable and cost-effective energy generation solution we were seeking.”

Building energy-efficient homes with Marley SolarTile®

Birch Grove’s three eco homes were designed for sustainability and to mitigate their impact on the environment. The seamless specification and installation of Marley’s SolarTile® – as part of a holistic renewable system – has been central to the eye-catching development’s success, meaning it has attracted climate-aware buyers.
