Melbourne-based cleantech company Allume Energy announced on April 23, 2026, a significant milestone: its proprietary SolShare technology has now connected 10,000 apartments to rooftop solar energy across Australia, the UK, USA, and Germany. This achievement marks a critical step forward in addressing the long-standing challenge of solar access for residents in multi-unit dwellings (MUDs), a segment of the housing market traditionally excluded from the benefits of rooftop solar.
The inability for apartment residents to directly benefit from solar power due to shared roof space, complex metering arrangements, and landlord-tenant dynamics has been a persistent barrier to broader renewable energy adoption. Allume Energy’s SolShare system offers a pragmatic solution, enabling a single rooftop solar installation to be shared among multiple apartments within the same building. This development is particularly pertinent for Australia, where a significant portion of the population resides in apartments, and the demand for clean, affordable energy continues to rise.
The SolShare Solution: Democratising Rooftop Solar
At its core, the SolShare technology acts as a smart energy management system, dynamically distributing solar power from a single rooftop array to individual apartments. Unlike traditional setups where solar energy is typically tied to a single meter, SolShare intelligently allocates electricity based on real-time demand, ensuring each connected apartment receives a share of the generated solar power. This innovative approach means that residents can directly offset their electricity consumption with solar energy, leading to tangible reductions in their power bills without needing to install individual solar systems or navigate complex strata body approvals.
“These projects show the opportunities for First Nations-led design and co-development of local energy solutions, improving reliability, lowering costs and reducing reliance on diesel,” Miller said.
The system’s ability to overcome the technical and administrative hurdles of MUDs has positioned it as a key enabler for equitable solar access. For many apartment dwellers, the promise of solar savings has remained out of reach. With SolShare, the benefits of renewable energy, previously exclusive to detached homes, are becoming a reality for a wider demographic.
Impact on Australian Apartment Living in 2026
Australia’s residential solar market is among the most advanced globally, with over 4.3 million households now boasting rooftop solar panels. However, this impressive uptake has largely been concentrated in detached homes. The multi-unit dwelling sector, encompassing apartments, townhouses, and strata complexes, represents a significant untapped resource for solar generation. Allume Energy’s milestone directly addresses this gap, offering a proven pathway for urban density to contribute to the nation’s renewable energy targets.
For residents, the primary benefit is access to cheaper, cleaner electricity. With rising electricity costs a constant concern, the ability to reduce reliance on grid power, particularly during peak daytime hours, translates into meaningful savings. While specific AUD savings vary based on system size, consumption patterns, and local tariffs, the principle of direct solar consumption offers a stable hedge against market volatility. For instance, a typical apartment might see reductions on the ‘supply’ component of their bill or a lower per-kilowatt-hour rate for solar-sourced electricity.
Furthermore, the integration of solar into apartment buildings enhances their environmental credentials, contributing to lower carbon footprints and improving building energy ratings. This can increase the attractiveness of properties for environmentally conscious tenants and owners.
The Broader Grid and Policy Implications
Beyond individual bill savings, the widespread adoption of shared solar solutions in MUDs can have positive implications for the broader electricity grid. By increasing distributed generation within urban areas, it can help reduce strain on network infrastructure and minimise the need for costly grid upgrades. It also supports the national transition towards a higher penetration of renewable energy. As Australia aims for an 82% share of renewables in the National Electricity Market (NEM) by 2030, technologies like SolShare play a crucial role in diversifying generation sources and integrating more clean energy into the urban fabric.
While the federal government’s Small-scale Renewable Energy Scheme (SRES) primarily supports individual rooftop solar installations through Small-scale Technology Certificates (STCs), the indirect benefits of technologies enabling MUD solar contribute to the scheme’s overall objectives. State-level initiatives or future policy adjustments could further incentivise such shared solar models, recognising their unique value proposition in complex urban environments.
For those considering the financial aspects of solar and battery integration, understanding various funding mechanisms is key.

What’s Next for Shared Solar?
Allume Energy’s achievement of 10,000 connected apartments underscores the growing viability and demand for shared solar solutions. The company’s international expansion demonstrates the global applicability of its technology, with lessons learned from diverse markets potentially accelerating adoption within Australia. As more apartment buildings across New South Wales, Victoria, and Queensland look to embrace renewable energy, systems like SolShare offer a blueprint for overcoming traditional barriers, ensuring that the benefits of solar power are accessible to all Australians, regardless of their housing type.
This milestone highlights a shift towards more inclusive energy solutions, paving the way for a future where apartment dwellers are active participants in Australia’s clean energy transition. The focus will likely continue to be on streamlining installation processes, optimising energy distribution, and demonstrating clear financial returns for both residents and building owners.
