Australia's solar revolution has left many apartment dwellers in the shade, with a significant gap in renewable energy access. This article delves into the challenges and opportunities for bridging this solar divide.
The Solar Gap
Australia leads the world in household solar adoption, yet a large portion of its population, residing in apartments or units, remains disconnected from this green energy source. Research reveals a stark contrast: 39% of detached or semi-detached homes boast solar panels, compared to a mere 6% of apartments. This disparity extends to battery storage, with a 7% installation rate in houses versus 3% in apartments.
Ashley Bradshaw, Executive Manager at Energy Consumers Australia, highlights the issue: "Most solar installations are on stand-alone homes." The reasons are multifaceted, ranging from shared roof space and common area usage to body corporate rules and electricity metering complexities.
Navigating Apartment Solar
Installing solar on an apartment building is a unique challenge, as Kate Nicolazzo from Let Me Be Frank agency explains. It involves governance, group decision-making, and potential barriers like rental status or lower incomes. However, with new technologies and incentives, now is an opportune time to explore solar options.
Solar System Designs for Apartments
There are two primary solar system setups for apartment buildings. The first involves multiple solar systems with separate inverters wired to individual flats. The second is a shared system where the electricity generated from a single installation is distributed equitably among dwellings or used for common areas.
Allume Energy, a Melbourne-based company, has developed a solution called SolShare. This technology acts as a "traffic controller" for solar, allocating energy to maximize savings while ensuring a fair share for each apartment. It simplifies the process by eliminating the need for multiple installations and individual inverters.
Benefits and Challenges
While it may seem complicated, there are advantages to apartment solar. Lower-rise buildings often have ample roof space for solar panels, and their height reduces shading issues. However, installation can be complex, and other technologies like balcony solar face hurdles due to safety and metering rules.
Overcoming Administrative Hurdles
A significant challenge for apartment residents is the decision-making process within strata associations or body corporates. Owners corporations and property managers can introduce barriers, from voting thresholds to bylaws, making agreement difficult. Some states, like Victoria, require a 75% owner agreement for certain decisions, which can be a lonely and time-consuming process.
Resources and Support
Fortunately, there are resources available to guide apartment residents through the process, including how-to guides from organizations like Yarra Energy Foundation, Port Phillip city council, High Life Living, and the Victorian government. These resources provide a step-by-step approach to navigating the complexities of solar installation in apartments.
Alternative Energy-Saving Options
Apart from solar, there are numerous ways for apartment dwellers to save on energy costs. Switching to different electricity plans, adopting electric appliances, and implementing smaller, low-cost energy-saving measures can all contribute to reduced energy bills. As Bradshaw notes, "There are lots of ways to save money on electricity bills; it's about finding what works best for your circumstances."
Conclusion
While Australia's solar success story has primarily benefited detached homes, the potential for apartment solar is significant. With innovative technologies, generous incentives, and a growing awareness of the benefits, the future looks brighter for apartment dwellers looking to join the renewable energy revolution. It's a complex journey, but with the right support and resources, the solar gap can be bridged, ensuring a more sustainable and equitable energy landscape for all.
