The federal government’s new solar battery rebate, announced as part of the 2025 budget, is an important piece of the puzzle that is Australia’s energy transition and quest for net-zero by 2050.

While one in three Australian homes has solar panels, shockingly, only one in 40 is equipped with a battery. That’s about to change.

From July 1, eligible households across Australia will be able to get a 30 per cent upfront discount on solar batteries, unlocking long-term power bill savings, helping to reduce grid pressure, and supporting the country’s carbon-neutral mission.

But, what does the rebate really mean for Australian homeowners and how does the scheme fit into the bigger picture?

How much could you save?

The scheme “is a win for family budgets and for the country’s energy transition”, Solar Battery Group chief executive James Hetherington said.

“The savings are significant. A family with a five-kilowatt solar system and a 10-kilowatt battery can trim grid usage by about 60-80 per cent. At today’s tariffs, that’s roughly $2300 a year.”

Importantly, the benefit appears from the very first bill – provided usage habits remain consistent.

And the savings go beyond reduced power bills. Lower energy costs translate into an increase in disposable income, which is always a good thing in today’s economy. An LBL report found that even a $100 drop in annual energy costs leads to a 2.3 per cent drop in mortgage default odds.

How does the rebate work?

Unlike state schemes, the federal rebate applies at the point of sale.

“From July 1, 2025, the accredited installer applies the 30 per cent federal discount; you see the price reduction on your invoice and the installer later redeems the value,” Hetherington said.

This makes it simpler and more immediate than many state incentives, which typically provide fixed rebates or interest-free loans after installation.

The federal solar scheme is national, uncapped, and percentage-based, with a one-battery-per-household limit. Importantly, it is not means-tested.

Can I combine it with state incentives?

The short answer that we all want to hear is yes!

“The Commonwealth has designed the new rebate to be ‘stackable’,” Hetherington said.

“In Victoria, NSW or Western Australia, for example, you may add the 30 per cent discount to your state rebate or loan, provided the combined support does not exceed the installed cost.”

It’s important to note that while the battery rebate scheme is “stackable”, other available incentives and schemes vary by state. Check your relevant state government website for more details.

Who’s eligible – and what are the traps?

Eligibility is broad, with owner-occupiers, landlords and small businesses connected to the grid all able to access the rebate, as long as they install an approved battery of five-100 kilowatts through a Clean Energy Council-accredited installer.

As with any new government scheme, there are some early misconceptions.

“Retrospective claims on existing batteries are not allowed,” Hetherington said.

He also pointed out that “taking the federal rebate does not cancel your state incentive”.

What are people asking – and what should they ask?

Since the government announcement, inquired have tripled at Solar Battery Group – Australia’s largest supplier of solar batteries.

Most people want to know how cheap a battery can be.

But Hetherington said better questions were: “What is my evening usage profile? What is the warranty of batteries? Can the system join a virtual power plant?”

For those new to the solar conversation, a virtual power plant (VPP) probably sounds more like science fiction than reality. However, there are many across Australia.

In Victoria, for example, more than 700,000 households use solar energy.

Essentially, a VPP creates a microgrid. By connecting individual household batteries in an energy-sharing network, small amounts of surplus energy can be fed back for use by others in the community.

This helps balance supply and demand on the electricity grid, and also reduces individual power bills as you can even be paid for your contribution.

Asking the questions Hetherington suggested, as well as finding out if your community has a VPP, will help to determine the real-world performance and revenue potential of your solar energy system.

What kind of system does a typical home need?

Size depends on your night-time energy use and the capacity of your solar panels.

It is most important that your chosen battery can store every kilowatt of precious energy generated by your solar panels so that none is lost.

“Most families would require a 10-kilowatt unit, which after the rebate, allows us to bring our prices down to $5000,” Hetherington said.

When will I break even?

As with anything to do with property, return on investment is always top of mind. Thanks to the rebate, payback periods have shrunk dramatically.

“Most households can expect a return on investment in three to four years,” Hetherington said. “Well within the 10-year product warranty and well before the battery’s 15-year expected lifespan.”

How can I check I’m not being misled?

“Make sure you do your research,” Hetherington said.

“Start by understanding your power consumption and current solar generation. Then check the Clean Energy Council-approved suppliers and products list and speak to a certified installer.”

Once again, energy.gov.au has excellent guides and resources to help with the switch to solar – from installation, maintenance, figuring out what size system you need, to estimating savings.

Beyond bills: What else can a battery do for me?

The benefits of a solar battery storage system go beyond cutting costs.

“[They include] blackout resilience, the ability to join virtual power plants and earn credits, readiness for EV charging, higher property value, and a lower carbon footprint,” Hetherington said.

“It also eases peak-demand pressure on the grid.”

Energy-efficient homes also command premium sale prices, which is music to any property owner’s ears.

But there are far greater benefits to owning and living in an energy efficient, sustainable home. Prefab modular home website Ecolive notes: “A sustainable energy-efficient home provides lifestyle benefits, such as cross-ventilation, north-facing orientation, heat-recovery ventilation, and solar panels.”

Is now the right time to act?

On a macro level Australia has a goal of net-zero carbon emissions by 2050.

“A strong Australian contribution to emissions reduction helps in the global effort to reduce major environmental, health and economic risks from the dangerous effects of climate change,” the Department of Climate Change, Energy, the Environment and Water says.

“This global effort is essential to protecting Australia from the worst climate impacts.”

You might be thinking “I’m all for playing my part, but what impact will transitioning to solar really have in the grand scheme of things?”. You’d be surprised.

On a micro level, individual household choices also have a significant role.

“Residential buildings are responsible for around 24 per cent of overall electricity use and more than 10 per cent of total carbon emissions in Australia,” the department says.

The time to act is now, and there is no time like the present – especially when it comes to climate change and taking full advantage of government incentives.

“Early adopters capture the full 30 per cent discount; the percentage tapers down each year to 2030,” Hetherington said.

With 2050 just 25 years away, winter bills looming and installer demand set to spike, getting your ducks in a row – including working out energy needs and doing due diligence on installers – will put you in the perfect position to maximise savings and realise the benefits when July 1 arrives.
