Selling solar back to the grid earns you somewhere between 5 and 12 cents per kilowatt-hour. Buying it back from the grid in the evening costs you 30 cents or more. A home battery closes that gap — and the federal government still covers a meaningful share of the cost to install one.
The Cheaper Home Batteries Program has been running since July 2025. It applies a direct upfront discount to the cost of an eligible battery installation — no applications, no waiting, no paperwork on your end. On 1 May 2026 the rebate stepped down to a lower rate, and a size-based tiered structure came into effect. It remains one of the most significant incentives available to Gold Coast homeowners — it is simply less generous than it was in the program’s opening months.
Here is what you can claim now, and how to work out whether a battery makes sense for your home.
Key Points
- The federal Cheaper Home Batteries Program gives an upfront discount on eligible home batteries, applied directly on your invoice — no paperwork required
- Since 1 May 2026 the rebate is worth roughly $250 per usable kWh (down from about $330 before the step-down) — around $2,500 on a typical 10 kWh battery
- A size-based tier now applies: capacity up to 14 kWh earns the full rate, 14–28 kWh earns 60%, and 28–50 kWh earns 15%
- No means testing — open to all homeowners; retrofits onto existing solar are fully eligible; one rebate per property
- The rate is scheduled to keep stepping down in future years, so installing sooner still captures more value — but the hard 1 May deadline has now passed
How Much Is the Rebate Worth on the Gold Coast?
The rebate is calculated on your battery’s usable storage capacity in kilowatt-hours (kWh). Since 1 May 2026, eligible batteries earn 6.8 Small-scale Technology Certificates (STCs) per usable kWh, down from 8.4 before the step-down. In dollar terms that works out to roughly $250 per usable kWh as an upfront discount, applied before you pay a cent.
Figures are indicative, updated June 2026 to reflect the 1 May step-down, and vary by property, existing system, and brand. The rebate is applied by your installer as a point-of-sale discount — what you see on your quote is what you pay, with nothing to claim back later. Get a tailored quote for accurate figures.
What Is the Cheaper Home Batteries Program?
The Cheaper Home Batteries Program is a federal initiative that launched on 1 July 2025. It uses the same Small-scale Renewable Energy Scheme that has reduced solar panel costs in Australia for over a decade.
When an accredited installer fits an eligible battery, they generate STCs based on the system’s usable capacity. Those certificates are assigned back to you as a discount on your invoice. You never see the certificates — you just see a lower price.
The program replaced the Queensland Battery Booster Program, which closed to new applications in 2024. If you are still seeing references to the Battery Booster online, those pages are out of date.
The federal Cheaper Home Batteries Program is the only battery rebate currently available to Gold Coast homeowners. Hundreds of thousands of Australian households have taken up the program since it launched, with Queensland among the strongest-responding states.
Who Is Eligible?
Eligibility is broader than most people expect. There is no means testing — the program is open to all homeowners, small businesses, and community organisations regardless of income.
To qualify, you need:
- An eligible battery on the CEC approved product list, with usable capacity between 5 kWh and 100 kWh — GoodWe’s Lynx F G2 range (9.6–25.6 kWh), Tesla Powerwall, and Sungrow all qualify
- Installation by a CEC-accredited solar retailer
- An existing or new rooftop solar system connected to the battery
- A battery that is VPP-capable (able to technically connect to a Virtual Power Plant — you do not have to actually join one)
- One rebate per property (per NMI/electricity meter)
Retrofitting a battery onto existing solar is fully eligible. Around 30% of Gold Coast homes already have rooftop solar — if yours is one of them, you do not need new panels. Your existing system just needs to be compatible with the battery being installed.
How the Rebate Works Now (From 1 May 2026)
Two things changed on 1 May 2026, and both are now in effect.
The base rebate rate dropped. The STC factor reduced from 8.4 to 6.8 STCs per usable kWh of battery capacity. In dollar terms, that is roughly $250 per usable kWh — around $600–$700 less on a standard 10 kWh battery than in the program’s opening months.
A size-based tiered structure applies. The rebate is no longer flat across all battery sizes:
- Capacity up to 14 kWh: full (current) rate
- 14–28 kWh: 60% of the base rate
- 28–50 kWh: 15% of the base rate
- Above 50 kWh: no further rebate support
For most Gold Coast homes installing a 10–13.5 kWh battery, the full rate still applies to the whole system, because that capacity sits under the 14 kWh threshold. The tiering mainly affects larger systems designed for high overnight usage.
The restructure happened because the program proved far more popular than projected — average installed battery sizes had climbed to around 23 kWh, nearly double what the government anticipated. The tiering is designed to extend the program’s funding through to 2030, and the rate is reviewed at least annually with further step-downs scheduled. The practical takeaway: the rebate will keep reducing over time, so installing sooner still captures more value — but the urgency is now a gradual one, not a hard deadline.

The Self-Consumption Advantage: Why Storing Beats Selling
The rebate reduces what you pay upfront. But the reason a battery makes long-term financial sense on the Gold Coast comes down to a basic energy economics problem.
Feed-in tariffs in South East Queensland — what your electricity retailer pays for surplus solar you export to the grid — currently sit between 5 and 12 cents per kWh. The rate you pay to import power from the grid runs at 30 cents or more. The gap has never been wider.
Here is what that means in practice for a Gold Coast home with a 6.6 kW solar system that currently exports 3,000 kWh per year:
With the federal rebate applied, payback periods for most Gold Coast homes with existing solar are typically in the range of 6–8 years — indicative, and within the battery’s 10-year warranty for households that use most of their stored energy. That is the combination of a still-meaningful STC discount, cheaper hardware than a few years ago, and genuinely unfavourable export rates that make self-consumption compelling.
There is also a non-financial benefit worth naming. South East Queensland sits in a severe storm corridor. The disruption caused by Cyclone Alfred in 2025 was a reminder that grid outages on the Gold Coast are not rare events. A battery-backed solar system keeps essential circuits running when the street goes dark — no generator required.

Is a Battery Still Worth It Now? — An Honest Answer
The rebate is smaller than it was, but the underlying case for a battery on the Gold Coast has not changed much: the gap between what you are paid to export and what you pay to import is what really drives the return, and that gap is still wide.
A battery is likely a good fit if: you have an existing solar system generating more power than you use during the day, you are home in the evenings to actually consume the stored energy, and you are planning to stay in your home for at least five years.
It may be worth waiting or reconsidering if: your solar system is ageing and due for replacement, your overall electricity usage is very low, or you are planning to sell the property in the near term.
If you are unsure, a free assessment costs nothing and gives you the actual numbers for your situation.
Rebate values and STC rates are indicative as at March 2026 and subject to change. Installed costs vary by property and system. Contact Solar Set for a quote specific to your home.

Frequently Asked Questions
Is the QLD Battery Booster Program still available?
No. The Queensland Battery Booster Program closed to new applications in 2024. The only battery rebate currently available to Gold Coast homeowners is the federal Cheaper Home Batteries Program. If you have seen websites still referencing the Battery Booster, that information is out of date.
How much is the federal battery rebate worth now?
Since 1 May 2026, the rebate is worth roughly $250 per usable kWh of battery capacity (based on 6.8 STCs per kWh), applied as an upfront discount on your invoice. That is around $2,500 on a typical 10 kWh battery. The exact figure depends on the battery’s usable capacity and the prevailing STC price, so your quote is the accurate number.
How does the size-based tier work for bigger batteries?
Capacity up to 14 kWh earns the full rate. Capacity between 14 and 28 kWh earns 60% of the rate, and between 28 and 50 kWh earns 15%. Capacity above 50 kWh receives no further rebate. For most homes installing a 10–13.5 kWh battery, the full rate applies to the whole system because it sits under the 14 kWh threshold.
What size battery does a Gold Coast home typically need?
For a home with a 6.6 kW solar system and average overnight usage, a 10–13.5 kWh battery covers most households comfortably. Larger systems (19–26 kWh) suit households with higher overnight consumption — electric vehicles charged at home, home offices running through the evening, or large families. Solar Set will size the battery to your actual usage patterns, not a generic recommendation.
Is the GoodWe Lynx F G2 eligible for the rebate?
Yes. GoodWe’s Lynx F G2 range — available in 9.6, 12.8, 19.6, and 25.6 kWh configurations — is fully CEC-approved and eligible under the Cheaper Home Batteries Program.
Do I need to join a Virtual Power Plant?
No. Your battery must be technically capable of VPP connection — meaning it has the hardware and software to participate — but you are under no obligation to actually join a VPP program. It is a hardware specification requirement, not a participation requirement.
I already have solar panels. Can I still claim the rebate for adding a battery?
Yes, retrofitting a battery onto an existing solar system is fully eligible. Roughly 30% of Gold Coast homes already have rooftop solar — the program was specifically designed to include retrofit installations, not just new combined solar-and-battery setups.
How does Solar Set apply the rebate — do I need to do anything?
Nothing. The rebate is applied directly to your invoice by Solar Set as a point-of-sale discount. You never fill in a form, lodge a claim, or wait for a payment to arrive. Solar Set handles all STC registration and CEC compliance paperwork on your behalf. Your only decision is whether to proceed with the installation.
Can I get the rebate without solar panels?
No. The battery must be connected to an existing or new rooftop solar system. A standalone battery with no solar does not qualify under the Cheaper Home Batteries Program.
