Australian Solar Batteries Installations on the Rise
The data, collected by the Clean Energy Regulator and analyzed by SunWiz, reveals a substantial increase in solar battery installations across Australia. July 2025 saw Australians install 2,766 solar batteries, surpassing the previous monthly record set in March 2023 and significantly exceeding June 2025’s total of 1,962 new batteries. This surge reflects a growing national interest in residential battery storage, likely driven by increasing electricity prices and a desire for energy independence. Despite these impressive national figures, the uptake of battery installations varies considerably across different regions. Victoria leads the charge with 1,049 new batteries installed in July, followed by New South Wales (572), Western Australia (375), and Queensland (347). South Australia and the Australian Capital Territory contributed 160 and 155 new batteries, respectively, while Tasmania and the Northern Territory recorded more modest installations with 77 and 31, respectively.
Exploring the Factors Behind the Surge in Australian Solar Batteries
Several factors may be contributing to the recent surge in solar battery installations. The increasing popularity of Virtual Power Plant (VPP) programs, offering financial incentives and advanced energy management features, is undoubtedly a key driver. Furthermore, the average capacity of newly installed batteries has increased to 10.8 kWh, compared to 9.4 kWh in 2024. This suggests a growing need for more robust energy storage solutions to power larger homes and increasingly energy-hungry appliances. However, the precise influence of VPPs on this upward trend requires further investigation. SunWiz Managing Director Warwick Johnston notes that while VPPs are gaining traction, the direct correlation between rising battery installations and VPP membership isn’t definitive. The battery market remains volatile, influenced by fluctuating factors such as pricing, consumer demand, and the rate of solar panel installations.

Impact of Feed-in Tariffs on Australian Solar Batteries
Feed-in tariffs (FiTs), payments to solar panel owners for excess electricity fed back into the grid, have historically influenced solar adoption rates. Currently, the relatively low FiT rate of around 4 cents per kWh may not sufficiently offset the high upfront costs of battery installation for many households. At this rate, it could take over 20 years to recoup the battery investment through FiT payments alone. Despite this, the continued decrease in battery prices, coupled with potential government incentives and rebates, could encourage more homeowners to invest in solar energy storage. The rising popularity of home batteries also fuels interest in VPPs, allowing homeowners to store and sell excess energy back to the grid, generating additional income. This development, alongside the news of cancelled federal programs like “Solar for All” [2], highlights the shifting landscape of solar incentives and the increasing role of private initiatives.
The Future of Australian Solar Batteries Installations
As battery technology continues to advance and costs decline further, the growth trajectory of solar battery installations in Australia is expected to remain strong. More affordable and efficient batteries empower homeowners to reduce grid reliance, lower energy bills, and contribute to a more sustainable energy future. The shift towards energy independence is also driving global trends, as seen in the Philippines securing financing for large-scale solar projects [1]. Looking ahead, the convergence of decreasing battery costs, government support, and the increasing desire for energy autonomy is poised to further accelerate the adoption of solar battery systems, reshaping Australia’s energy landscape and contributing significantly to national renewable energy targets.
