Allume Energy’s SolShare technology is the winner of the Most Innovative Product (Hardware) at the Housing Digital Innovation Awards 2023 in Birmingham.
The SolShare technology was selected as the world’s only solution for connecting multiple flats to a single rooftop solar PV system.
Without the SolShare, solar energy for flats is technically and financially infeasible; it allows people who live in flats to finally access clean, affordable electricity.
A SolShare PV system typically adds between 5-15 SAP points to a flat for a total cost of just £2,000-£4,000 per flat. It saves an estimated 25% in installation costs as compared to a typical solar system and typically reduces the energy bills of apartment residents by 40%.
Allume Energy extends thanks to Housing Digital for creating the opportunity to celebrate the dedication and drive of everyone striving for innovation and excellence in UK housing.
