Solar Battery Rebate on the Gold Coast: What You Get and What a Battery Costs After It

Ask around the Gold Coast and plenty of people will tell you the battery rebate is finished. They are thinking of Queensland’s Battery Booster program, which closed in May 2024. What replaced it is a federal discount that is worth more for most homes, has no income test, and comes straight off the installer’s invoice. Here is what it is worth, what a battery costs after it, and why the next few weeks matter.

Is there still a battery rebate in Queensland?

Yes. It is the federal Cheaper Home Batteries discount, and it applies in every Gold Coast postcode. It is worth about $250 for each usable kilowatt hour on the first 14 kWh of battery capacity. In round figures:

• A 10 kWh battery attracts about $2,500.
• A 13.5 kWh battery attracts about $3,400.
• A 20 kWh battery attracts about $4,400, because the rate reduces above 14 kWh.

There is no application form. Your installer claims the discount and takes it off the price. Queensland does not add a state amount on top, so this is the whole upfront rebate.

What a battery costs on the Gold Coast, before and after

Most South East Queensland quotes for a 10 kWh battery fall around $9,000 to $11,000 installed. After the discount that comes to around $6,500 to $8,500. A 13.5 kWh battery, the size many family homes choose, typically lands around $8,600 to $10,600 after the discount.

Three things move the price most: the brand of battery, whether your switchboard needs work, and whether you want backup power when the grid goes down.

Who can claim it

The battery has to be paired with rooftop solar, either new or existing. That means if you already have panels, you can add a battery to them and still receive the discount. The battery must be on the Clean Energy Regulator’s approved list and be installed by an accredited installer. Homes, small businesses and community sites all qualify, and renters can install with the owner’s permission.

Why Gold Coast homes are adding them

Many Gold Coast homes send solar power to the grid during the day for a few cents, then buy it back in the evening at several times the price. A battery keeps that power for the 4pm to 9pm peak, which is when most households use the most.

Energex also limits how much power many newer solar systems can export. Solar you cannot export is worth nothing unless you store it.

Then there are the storms. After the long outages that followed ex-Tropical Cyclone Alfred in March 2025, backup power moved up the list for a lot of households. Backup usually needs extra equipment at the switchboard, so ask for it to be quoted as its own line.

Why timing matters this summer

The federal rate steps down on 1 January 2027, then again every six months until the program ends in 2030. The discount is set by the date the battery is installed, not the date you sign.

Install lead times on the Coast commonly run four to eight weeks in the lead-up to summer. A contract signed by early November is the realistic way to be installed at the current rate.

What to check on a quote

1. Usable capacity. The discount is calculated on usable kilowatt hours, so make sure the quote states that figure.
2. The discount as its own line. You should be able to see the full price, the federal discount and what you pay.
3. Backup. Check whether it is included, and what it covers during an outage.
4. Switchboard work. Ask whether any upgrade is needed and what it costs.
5. The installer. Only an accredited installer can apply the discount.

The short version

If you have solar on the roof and a power bill that peaks in the evening, a battery is worth pricing before the rate drops. Energy Rebate Check has a full guide to the solar battery rebate in Queensland, with worked examples by battery size and a postcode check.
