​​More than 2M Australians, 15M Americans, and 300M Europeans live in low and medium rise apartment buildings, with the roof space for solar, but no way of accessing it. We developed SolShare™ to bridge this gap. SolShare enables solar for apartments by sharing energy from a single rooftop solar system between multiple dwellings within the same building. This breaks down the technical and ownership barriers that have historically prevented apartment residents from accessing cheaper and cleaner energy from the sun. With an established market in Australia, Allume is now rapidly growing in the UK and the US.
