In Brisbane, the push towards solar energy isn't just about tapping into our abundant sunshine; it's also supported by Australian Government incentives that make going solar an attractive proposition. The solar and battery rebate schemes are key players in this shift, aimed at making solar installations more affordable for homeowners. Let's break it down, sifting through all the details and keeping it straightforward.
At its heart, the solar rebate, part of the Small-scale Renewable Energy Scheme (SRES), is designed to encourage Australians to generate their own clean energy. By installing solar panels, you earn Small-scale Technology Certificates (STCs) - think of them as discount coupons that reduce the upfront cost of going solar.
STCs are essentially a pat on the back for contributing to a cleaner environment. The number of STCs you can claim depends on how much energy your system is projected to produce up until 2030. So, the size of your system is a factor and where you live matters, too, as Australia is divided into zones based on solar exposure. Larger system + more sun = more STCs.
Curious about the discount you might get? For a typical 6.6kW solar system in Brisbane, you could see a reduction of about $1,700 - $1,900 thanks to STCs, depending on factors such as installation date and STC market value.
But here's the catch: the rebate value decreases each year until the scheme concludes in 2030. So sooner rather than later is the mantra if you want to maximise your savings.
As the rebate value diminishes annually, delaying your solar installation could mean less savings. In previous years, when the redeeming period was longer, the same 6.6kW system could have attracted rebates of over $2,600. But, as the scheme gradually phases down, fewer STCs are available each year.
Plus, installers get really busy towards the end of the year, trying to lock in the current year's STC prices for their customers. Getting ahead of the end-of-year rush not only ensures you get a better deal but also dodges the installation backlog.
The perks of installing solar extend beyond the initial rebate. There's also the feed-in tariff, rewarding you for any surplus power your solar system feeds back into the grid. These rates vary by electricity retailer, so it’s worth comparing your options.
In most cases, storing and using more of the solar power you generate will save more than exporting it, which is why many homeowners consider adding a battery. Even so, feed-in-tariffs remain an ongoing benefit that can help lower your future energy bills, making your investment in solar even more rewarding over time.
Since 1 July 2025, eligible home batteries can receive support through the Cheaper Home Batteries Program, a part of the Australian Government’s Small-scale Renewable Energy Scheme (SRES). Like solar panels, this is delivered as an upfront discount when you assign your STCs to your installer.
However, while batteries use the same STC framework as solar, the way incentives are calculated is slightly different, with additional factors based on battery size and installation timing.
A battery lets you store excess solar energy and use it later, helping reduce how much electricity you buy from the grid. It can also improve your savings depending on your tariff and usage patterns.
The battery must be new and installed with new or existing solar panels. Eligible systems are generally between 5kWh and 100kWh, and systems installed before 1 July 2025 don’t qualify.
STCs are only available for the first 50kWh of usable battery capacity. Larger systems can still qualify, but the rebate is capped at this level. Also, the general rule is that only one battery per premises can receive STCs.
Like the solar panel incentive, the battery incentive also reduces over time. This reduction is separate from the size-based tiers above, and affects the overall value of the STC rebate each year. The schedule has been set up for the STC factor to be lowered every six months, beginning May 2026 – so earlier installation can mean a bigger benefit.
The table below shows how STC values will change in the remaining years of the scheme:
For Queensland homeowners, leveraging the solar and battery rebate schemes is a smart move towards reducing energy costs and embracing a sustainable lifestyle. With both schemes winding down each year, acting quickly can secure you greater savings. Plus, the ongoing advantages of feed-in tariffs mean your solar panels continue to offer financial benefits long after they're installed. Whether it's the immediate cost reduction or the long-term savings, solar remains a worthwhile investment for Brisbane homeowners.
