Complete Guide to Solar Rebates in Queensland (2026)

Queensland offers some of the best solar incentives in Australia. Understanding the available rebates and incentives can significantly reduce your upfront costs and improve your return on investment. Here's everything you need to know.

Small-scale Technology Certificates (STCs)

STCs are the primary federal incentive for residential solar. When you install a solar system, you're entitled to a number of STCs based on your system size and location. These certificates have a monetary value and are typically traded by your installer, who applies the discount to your purchase price.

For a 6.6kW system in Brisbane, you can expect STCs worth approximately $2,500-$3,500. The exact value fluctuates based on the STC market price and the number of years remaining until 2030 (when the scheme is scheduled to end).

Feed-in Tariffs

When your solar system produces more electricity than you're using, the excess is exported to the grid. Your energy retailer pays you a feed-in tariff for this exported energy. In Queensland, feed-in tariff rates vary by retailer but typically range from 5-12 cents per kWh.

While feed-in tariffs have decreased over the years, they still provide a meaningful return. The key is to maximise self-consumption (using your solar energy directly) rather than relying heavily on feed-in tariffs.

Battery Incentives

While there's no specific Queensland state battery rebate currently, the federal STC scheme does apply to battery storage when installed with a new solar system. Some local councils also offer sustainability incentives that may apply to battery installations.

How to Maximise Your Rebates

To get the most from available incentives:

• Install sooner rather than later: STC values decrease each year as the scheme approaches its 2030 end date.
• Choose a CEC-accredited installer: This is mandatory to qualify for STCs.
• Use CEC-approved products: Both panels and inverters must be on the Clean Energy Council's approved product list.
• Compare feed-in tariff rates: Shop around for the best feed-in tariff from energy retailers.
