The Challenge

The project team needed a solar solution that could sit on a Bauder green roof without compromising the vegetation layer, and that could also feed solar energy fairly and compliantly to all individual flats. The roof had limited space and structure, requiring careful coordination between PV, roofing, and electrical design.

Our Solution

We installed a 20kW Bauder BioSolar system using high-efficiency Aiko 455W panels and a Solis 20kW inverter, mounted without penetrating the waterproofing. To distribute solar energy across the 14 dwellings, we integrated an Allume SolShare unit—a game-changing technology that enables equitable sharing of PV electricity in multi-occupancy buildings without the need for battery storage.

The Result

The system now generates clean energy for all residents, reducing grid demand and energy costs while maintaining the integrity and biodiversity of the green roof. The project was recognised at the 2024 Energy Efficiency Awards, winning Small Scale Project of the Year for its innovation, collaboration, and carbon-saving impact.

Why PV Plus

As an approved Bauder solar installer with expertise in biosolar systems, PV Plus was trusted to deliver a compliant, coordinated solution alongside Clarke Roofing. Our team managed the solar design, DNO application, and SolShare integration, ensuring everything met MCS, RC62, and GRO best practice standards.
