See what solar and battery rebates your home qualifies for

Solar and battery rebates, explained

Rebates, battery sizes and quotes can feel like a different language. Here is how it all fits together for a Queensland home, without the jargon.

How the federal Cheaper Home Batteries Program works

The Cheaper Home Batteries Program is a federal scheme that lowers the upfront cost of a home battery. It works through small-scale technology certificates. In practice that means your installer applies the discount on your quote, so you are not filling in forms or waiting on a payment later.

To qualify, the battery has to be an approved model and the installer has to be accredited. The battery is normally installed with solar, either a system you already have or one fitted at the same time. The amount depends on the usable size of the battery, and it can step down for larger batteries and change over time. That is why the exact figure always comes from your installer's written quote and the official program rules, not from a website headline.

How battery sizing works

A good battery is sized around your evenings and nights, not your roof. The question is simple: how much power does your home use once the sun has gone down? Air conditioning, cooking, lights, the pool pump and the TV all add up between about 5pm and 7am.

Your power bill shows your total use and, on many bills, a split between daytime and the rest. From that we estimate your overnight use, add a margin so the battery is not run flat every night, and round up to the nearest standard size. A bigger battery is not always better. One that never fills, or never empties, is money sitting idle. That is what the calculator and the bill check on this site show, using your own numbers.

What to check in a quote

• Approved battery. The exact make and model should be written on the quote and be on the approved list.
• Accredited installer. Ask who will do the work and whether they are accredited for batteries.
• Sizes in writing. Solar in kW, battery in usable kWh, and the inverter size.
• How the rebate is applied. It should be shown as a separate line, so you can see what it does.
• Warranty. Years, what is covered, and who you call if something goes wrong.
• Backup power. Whether the battery runs the house in a blackout, and which circuits it covers.
• What is left out. Switchboard upgrades, meter changes and extra cabling can sit outside a short quote.

Comparing two quotes? Make sure they describe the same size and the same equipment before you compare anything else.

Sigenergy, Sungrow and GoodWe

Sigenergy, Sungrow and GoodWe are three battery and inverter brands that installers in Australia commonly quote. They differ in things that matter at home: whether they suit single-phase or three-phase supply, how they behave in a blackout, how far the battery can be expanded later, and the warranty terms. We do not rank brands here. The right one depends on your roof, your switchboard and the way you use power, and we will talk you through the options for your home.
