How we calculated this

  • The rebate is the certificates (STCs) the battery earns, times the certificate price.
  • The certificates come from the usable capacity that counts and the factor for the install date.
  • Payback divides the cost after the rebate by the first-year saving at the electricity rates on this page.

Full method, tables and sources: Battery rebate calculator

  1. Check the battery qualifies

    13.5 kWh qualifiesdoes not qualify

  2. Find the STC factor

    May – Dec 2026: 6.8

  3. Weight the capacity

    13.5 kWh

  4. Count the certificates

    91 STCs(not eligible)

  5. Value the certificates

    91 × $37 = $3,367

  6. Work out payback

    $8,783 ÷ $881 = 10.0 years

This version starts with our default Queensland rates. The feed-in rate it starts with is our own pick for south-east Queensland. Regional Queensland has a regulated feed-in tariff, shown further down.

What else matters for a battery in Queensland

Queensland Solar Bonus Scheme (44c)

It pays 44c/kWh until its expiry date on 1 July 2028. You lose it if a battery runs while the solar system on the 44c is operating, unless the battery has a separate connection to the network. Check with your distributor before adding a battery.

For a home still on this scheme, the Add a battery to solar calculator works out a battery’s payback with the 44c payments counted.

Feed-in tariff in regional Queensland

In regional Queensland, on the Ergon Energy network, the regulated feed-in tariff is 6.006c/kWh.

The calculator on this page starts with 5c/kWh for Queensland. That is our own pick for the Energex network (Brisbane, south-east Queensland), so type the feed-in rate from your own bill.

Each row is for a battery installed between 1 May and 31 December 2026, at our default price of $900 per usable kWh before the rebate. Each row assumes 0.8 cycles a day, 90% round-trip efficiency and 2% battery wear a year: the defaults of the calculator on this page. Our default QLD rates are 27.9c/kWh to buy power (Dated third-party source: Canstar market average, 4 Sep 2026) and 5c/kWh for the solar you export (Estimate: WattMaths rounded pick. EnergyPlans (July 2026) lists retailer feed-in rates, not one state figure). Queensland has the sixth highest first-year saving of the 7 states and territories in our calculator, each at its default rates.
