Almost 4 million UK households live in medium and low rise apartment buildings, with the roof space for solar but, until recently, no way of accessing energy generated from it.

We didn’t think this was fair, so we developed a world-first technology, SolShare, which enables fair sharing of solar energy from a single rooftop solar PV system amongst multiple dwellings within the same building.

This breaks down the technical and ownership barriers that have historically prevented apartment residents from accessing free, clean energy from the sun. Born in Australia in 2015, Allume is now rapidly growing across three continents.
