Australia’s new federal solar battery rebate has had an immediate impact, with thousands of households taking up the incentive in its very first month.
From 1 July 2025, Australians became eligible to claim a rebate worth around 30% off the cost of a new solar battery when paired with rooftop solar. Early figures from the Clean Energy Regulator (CER) show a surge in demand, with almost 20,000 solar batteries installed in July 2025 alone.
If you’re still weighing up whether a solar battery is right for you, these numbers suggest many Australians are already moving quickly to secure the new rebate.
National Figures
- 19,592 solar batteries installed in July
- 356.6 MWh of new storage capacity added
- Average battery size: 18.2 kWh
This means Australians are choosing medium-to-large batteries, which are typically enough to power households well into the night.

Analysis: New South Wales and Queensland are leading in total installations, while the Northern Territory recorded the largest average system size at 22.4 kWh.
What This Means for Homeowners
The strong uptake highlights three key trends:
- Confidence in larger batteries – most new systems are well above 15 kWh, suggesting households want meaningful night-time coverage.
- Growing trust in rebates – with federal support now available, more Australians see batteries as financially viable.
- Momentum across all states – even in smaller markets like Tasmania and the ACT, uptake is visible.
If you’re considering a system, it’s worth exploring how the rebate applies in your state. Many households may also be able to stack the federal rebate with state-based programs such as the WA Battery Rebate or NT Battery Grant.
What Happens Next
The CER has confirmed that postcode-level battery installation data will be published from mid-August 2025, offering more detail about where uptake is strongest.
With nearly 20,000 batteries installed in month one, the rebate is already reshaping Australia’s energy landscape and momentum is expected to keep building.
