Selling solar back to the grid currently 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 right now, the federal government is covering roughly 30% 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. For a typical Gold Coast home, that discount currently sits between $3,300 and $4,600 depending on the system size.
There’s a timing element worth knowing about. The rebate structure changes on 1 May 2026. From that date, the discount steps down, and larger battery systems face a tiered reduction that significantly erodes the value. If adding battery storage has been on your list, now is the most favourable point in the program’s history to act.
Here’s everything you need to know.
Key Points
- The federal Cheaper Home Batteries Program delivers a ~30% upfront discount on eligible home batteries — applied directly on your invoice, no paperwork required
- Gold Coast homeowners can currently save $3,300–$4,600 on a 10–13.5 kWh battery before the rebate structure changes on 1 May 2026
- No means testing — open to all homeowners; retrofits on existing solar fully eligible; one rebate per property
- From 1 May, the rebate steps down and a tiered structure kicks in for batteries over 14 kWh — acting before then saves an extra $600–$700+ depending on system size
- With the rebate applied, payback periods have dropped to 5–7 years for most Gold Coast homes with existing solar — within the 10-year battery warranty for the first time
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). At current rates, you receive roughly $330–$340 per usable kWh as an upfront discount — applied before you pay a cent.
Installed costs are indicative and vary by property, existing system, and brand. Get a tailored quote for accurate figures.
The rebate is applied by your installer as a point-of-sale discount. What you see on your quote is what you pay — there’s nothing to claim back later.
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 Small-scale Technology Certificates (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’re 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.
Since launching in July 2025, more than 250,000 Australian households have installed batteries under the program. Queensland has been one of 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 don’t 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 don’t need new panels. Your existing system just needs to be compatible with the battery being installed.
What Changes on 1 May 2026?
Two changes happen simultaneously on 1 May.
The base rebate rate drops. The STC factor reduces from 8.4 to 6.8 STCs per kWh of battery capacity. In dollar terms, that’s roughly $600–$700 less on a standard 10 kWh battery.
A tiered structure kicks in for larger systems. Under the new rules:
- Batteries up to 14 kWh: full (new lower) rate
- 14–28 kWh: 60% of the base rate
- 28–50 kWh: 15% of the base rate
For a household installing a 13.5 kWh battery, that’s a difference of around $800 compared to installing before May. For a 20 kWh system designed for higher overnight usage, the gap is considerably wider.
The reason for the restructure: the program proved far more popular than projected. Average installed battery sizes jumped to 23 kWh — nearly double what the government anticipated. The tiering is designed to extend the program’s $7.2 billion funding through to 2030. The rebate continues to step down every six months after May.

The Self-Consumption Advantage: Why Storing Beats Selling Right Now
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’s 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 to a 10 kWh battery, payback periods for most Gold Coast homes with existing solar have come down to 5–7 years — within the 10-year battery warranty for the first time. That’s the combination of cheaper hardware, the STC discount, and genuinely unfavourable export rates that make self-consumption compelling.
There’s 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.

Should You Act Before May — An Honest Answer
The deadline is real and the savings are meaningful. But the best reason to install a battery is because it makes financial sense for your household — not purely to chase a rebate.
A battery is likely a good fit if: you have an existing solar system generating more power than you use during the day, you’re home in the evenings to actually consume the stored energy, and you’re 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’re planning to sell the property in the near term.
If you’re unsure, a free assessment costs nothing and gives you the actual numbers for your situation.

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’ve seen websites still referencing the Battery Booster, that information is out of date.
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 being 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. Solar Set has just received the latest Lynx F G2 stock on the Gold Coast. Read our overview of what the Lynx F G2 offers →
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’re under no obligation to actually join a VPP program. It’s 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 much less will the rebate be after 1 May 2026?
For a standard 10 kWh battery, approximately $600–$700 less. For a 13.5 kWh battery, approximately $800 less. For systems over 14 kWh, the new tiered structure reduces the rebate more significantly — the larger the battery, the wider the gap. The rebate continues to step down every six months after May through to 2030.
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.
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’ve seen websites still referencing the Battery Booster, that information is out of date.
