With electricity prices continuing to rise, more Australian households are looking for smarter ways to take control of their energy costs. While rooftop solar has helped thousands of families reduce their reliance on the grid, adding a home battery takes those savings even further by allowing you to store excess solar energy and use it when you need it most.
To make battery storage more affordable, the Australian Government has introduced the Cheaper Home Batteries Program, giving eligible households and small businesses a significant discount on the upfront cost of installing an approved battery system.
If you’ve been considering battery storage, now is one of the best times to invest. Here’s everything you need to know about the program, who is eligible, how much you could save, and why acting sooner could help you maximise your rebate.
The Cheaper Home Batteries Program is a Federal Government initiative designed to reduce the upfront cost of installing eligible home battery systems across Australia.
Rather than providing a cash rebate after installation, the program delivers its benefit through Small-scale Technology Certificates (STCs). These certificates create an upfront discount that is applied directly to the purchase price of an eligible battery installation.
The objective is simple—help more Australians store renewable energy, reduce pressure on the electricity grid, improve energy independence and accelerate Australia’s transition towards cleaner energy.
Whether you already own solar panels or are planning a complete solar and battery installation, the program makes battery storage significantly more affordable.
One of the biggest attractions of the program is the potential upfront saving.
Eligible homeowners can currently receive a discount of around 30% on the cost of an approved home battery.
For example:
The actual discount depends on:
The sooner you install, the greater your potential savings, as the STC value reduces over time.
Unlike limited grant programs that run out of funding, the Cheaper Home Batteries Program is designed to continue over several years.
However, there is one important difference.
The rebate gradually reduces over time.
This means homeowners who install earlier can secure a larger incentive than those who delay their decision.
Waiting another year may mean paying more for exactly the same battery system.
If you’ve already been thinking about battery storage, acting sooner allows you to maximise today’s available rebate while enjoying lower electricity bills sooner.
The program has been designed to support a wide range of Australian households and businesses.
To qualify, your battery system must meet several eligibility requirements.
Eligible battery systems must have:
Battery systems with a total capacity of up to 100kWh may still be installed, however incentives are only available on the first 50kWh of usable storage.
This makes the program suitable for both residential homes and many small commercial properties.
The battery must:
Installation must be completed by a suitably accredited installer using eligible products.
Working with an experienced installation company ensures your system is compliant while maximising available incentives.
Many solar households still purchase electricity from the grid every evening.
Without battery storage, excess solar generated during the day is typically exported back to the grid for a relatively low feed-in tariff.
A battery changes that equation.
Instead of exporting all your excess solar, you can store it and use it later when electricity prices are generally at their highest.
Benefits include:
For many households, battery storage is the final step towards maximising the value of their rooftop solar system.
Every household uses electricity differently.
A battery that’s too small may not provide enough evening power, while one that’s too large may not deliver the best financial return.
Factors to consider include:
An experienced energy consultant can analyse your consumption patterns and recommend the most suitable battery capacity for your home.
While reducing electricity bills is often the primary motivation, battery storage offers additional long-term benefits.
Store your own electricity and rely less on fluctuating electricity prices.
Use more of the renewable energy your solar system generates instead of exporting it.
Battery systems are becoming an important part of Australia’s future energy network, helping create a smarter and more resilient electricity grid.
Greater self-consumption of renewable energy means reduced dependence on fossil fuel-generated electricity, lowering your household’s carbon footprint.
For many Australian homeowners, the answer is yes.
The combination of:
makes this one of the strongest opportunities yet to invest in home energy storage.
Combined with an existing solar system, battery storage can significantly improve long-term savings while increasing energy independence.
