Charter House
In-roof solar PV integrated into a refurbished serviced-office building at Links Business Park, St Mellons.
Improving sustainability without compromising the building's design
Following the refurbishment of Charter House, the objective was to reduce the building's carbon footprint and improve environmental performance. The challenge was to introduce renewable energy generation in a way that complemented the building's appearance while maximising the potential of the available roof space.

A bespoke in-roof solar PV system
Nuvolt designed and installed a bespoke in-roof solar PV system integrated directly into the building's roof structure. The system was tailored to the building's dimensions, creating a seamless finish while generating renewable electricity on-site and reducing reliance on grid energy.
- Bespoke in-roof solar PV design
- Seamlessly integrated into the roof structure
- Maximised use of available roof space
- Reduced dependence on traditional energy sources
Lower emissions. Improved performance. A more sustainable building.
The completed installation helps Charter House generate renewable energy on-site while supporting its wider sustainability objectives. The project contributes to an annual reduction of approximately 1.82 tonnes of CO₂e and supports the building's achievement of an EPC A-rating, demonstrating the role renewable energy can play in improving both environmental and operational performance.
