Yes — Brisbane is one of the best places in Australia for solar. It gets ~4.2 peak-sun hours a day, sits in the federal STC rebate’s Zone 3, and runs hard on summer air-con — right when your panels are producing. In 2026 a quality 6.6kW system costs about $4,500–$7,500 after the rebate and usually pays for itself in around 3 years.
Are solar panels worth it in Brisbane?
For most Brisbane homes, solar is a standout investment. You’ve got abundant sun, retail power around 30c/kWh, and a climate that runs the air-con hard in summer — so you use a lot of your own solar during the day, which is exactly where the savings now live. Payback is commonly under three and a half years, and a quality system keeps saving for 20+ years.
The catch hasn’t changed: a good installer on a solid mid-range panel beats a cheap install on a premium one. The installer is the single biggest factor in whether your system performs.
How much do solar panels cost in Brisbane in 2026?
Typical fully-installed Brisbane prices after the federal STC rebate:
| System size | Panels | Price after rebate | Best for |
|---|---|---|---|
| 6.6 kW | 15–16 | $4,500 – $7,500 | Average home (avg ~$5,600) |
| 10 kW | 22–24 | $8,000 – $13,000 | Ducted air-con, pool, EV |
| 13 kW | 30–32 | $10,000 – $15,000 | All-electric / high-use, + battery |
The federal STC discount (~$2,400–$2,800 on a 6.6kW in Brisbane) is already included. Full breakdowns in our system size & price guides.
The QLD Solar Bonus Scheme — then vs now
Queensland’s 44c feed-in scheme drove a huge early-2010s boom. It’s long closed to new applicants (legacy 44c customers are paid until 30 June 2028), and there’s no state feed-in tariff today — but as an investment, solar still stacks up just as well, because system prices have collapsed.
5kW system for ~$12,500, earning a 50c feed-in tariff. Payback ≈ 5 years.
6.6kW system for ~$5,600, earning through bill savings. Payback ≈ 3 years.
Feed-in tariffs in Queensland (2026)
QLD has no single state-wide scheme — it depends on your network:
South-East QLD Energex
No mandated minimum. Feed-in is a voluntary retailer contribution, so rates are competitive and vary by plan — commonly ~5–12c/kWh, with some conditional offers higher.
Regional QLD Ergon
QCA-set mandatory rate: 8.66c/kWh in 2025-26, dropping to 6.006c/kWh from 1 July 2026.
Rebates for solar in Brisbane (2026)
- Federal STC discount — the main rebate on the panels, ~$2,400–$2,800 on a 6.6kW Brisbane system, applied upfront. (Brisbane is STC Zone 3.)
- Federal Cheaper Home Batteries Program — ~30% off an eligible battery, about $3,500 on a 10kWh unit.
- QLD Battery Booster — the state battery rebate is now closed, so the federal battery rebate is the one to use.
Should you add a battery?
Increasingly, yes. With feed-in tariffs low and power ~30c/kWh, storing daytime solar to run the evening air-con is worth far more than exporting it. The federal rebate cuts ~30% off an eligible battery (~$3,500 on 10kWh). A 10–13kWh battery suits most homes.
What size system should you get?
The old 5kW default is long gone. With cheap panels, low feed-in and Brisbane’s love of air-con, pools and EVs, many homes now install 10kW or more. Size it to your usage so you self-consume as much as possible.
Is Brisbane’s climate good for solar?
Mostly excellent — with a twist. Panels produce less on extremely hot days than on mild sunny ones, because heat raises cell temperature and reduces efficiency. Brisbane’s heat, hail and the odd cyclonic blow up north make panel choice and install quality matter more here than in milder cities. Quality panels are built to ride out hail and storms, and your installer should use racking rated for Brisbane’s wind zone.
Types of solar panels for Brisbane
This has flipped since the early 2010s: poly is effectively obsolete, and today almost every residential panel is monocrystalline. Your real choice is good mono vs premium mono — not mono vs poly.
Mono (N-type / TOPCon)
The 2026 standard. High efficiency, better performance in heat and low light, strong warranties. The right choice for most Brisbane homes.
Premium mono
Top-tier efficiency and build (e.g. for small or premium roofs). Real-world yield isn’t dramatically higher, but you fit more capacity in less space.
Thin film
Niche. Uniform black and good-looking, but expensive and rarely worth it for homes. Polycrystalline has been phased out entirely.
Solar inverters — what’s used in Brisbane
String inverter
The default for most homes (single-phase, or three-phase for larger/3-phase homes). Cost-effective and reliable on simple roofs.
Micro & optimisers
Panel-level performance and monitoring — worth it on roofs with shading or multiple orientations.
Hybrid (battery-ready)
Increasingly the default for anyone adding storage now or later. Saves a swap-out when you add a battery.
Best panels for Brisbane — what to look for
- Low temperature coefficient (~−0.30%/°C or better on N-type) so you lose less output in the heat.
- Strong, claimable warranty from a manufacturer with an Australian presence.
- Hail & load ratings suited to QLD conditions (most quality panels are well-rated).
- Cyclone-rated racking & fixtures if you’re in an exposed or northern location.
- A reputable, accredited installer — the best panel installed poorly will underperform.

Frequently asked questions
Are solar panels worth it in Brisbane?
Yes. Strong sun, ~30c/kWh power and heavy summer air-con use mean a well-sized system typically pays for itself in under 3.5 years and saves money for 20+ years.
How much does a solar system cost in Brisbane in 2026?
After the federal rebate, expect roughly $4,500–$7,500 for 6.6kW (average ~$5,600) and $8,000–$13,000 for 10kW, depending on brand and roof.
What is the solar feed-in tariff in Brisbane?
South-East QLD (Energex) has no mandated rate — retailers set their own, commonly ~5–12c/kWh. Regional QLD (Ergon) is QCA-set at 8.66c in 2025-26, dropping to 6.006c from 1 July 2026.
Are mono or poly panels better for Brisbane?
Almost all panels today are monocrystalline — poly is effectively obsolete. Choose a quality mono (ideally N-type/TOPCon) with a low temperature coefficient so you lose less output in the heat.
Is it worth getting a battery in Brisbane?
Increasingly, yes — daytime exports earn little while power costs ~30c/kWh, and the federal Cheaper Home Batteries rebate takes ~$3,500 off a 10kWh battery. Storage lets you run evening air-con on your own solar.
