Brisbane enjoys around 5.2 peak sun hours per day on average — one of the highest solar exposure rates of any major Australian city. That translates directly into electricity production, and electricity production translates into savings. But how much exactly?
At East West Solar and Electrical, we've helped hundreds of households across South East Queensland go solar. Here's what the numbers actually look like.
Average Brisbane Solar Savings by System Size
The savings you achieve depend on your system size, your daytime energy consumption habits, and your electricity tariff. Here's a general guide based on SE Queensland conditions and current electricity rates:
| System Size | Daily Production | Payback Period |
|---|---|---|
| 6.6kW | ~27 kWh | 3–4 years |
| 10kW | ~40 kWh | 3.5–5 years |
| 13.2kW | ~54 kWh | 4–5.5 years |
Estimates based on 28c/kWh consumption rate, 8c/kWh feed-in tariff, and 30% self-consumption. Actual results vary by household.
Understanding Your Solar Bill Credits
Your solar savings come from two sources:
- Self-consumption savings: Power you generate and use directly avoids paying grid electricity (currently ~28–34c/kWh in SEQ). This is where the bulk of savings occur.
- Feed-in tariff credits: Excess power exported to the grid earns a credit (typically 6–10c/kWh from most retailers in Queensland). This is lower than consumption savings, which is why maximising self-consumption matters.
How to Maximise Your Solar Return
Getting the most from your solar investment isn't just about panel count — it's about smart usage:
- Run appliances during the day: Dishwasher, washing machine, pool pump — set timers to run between 9am and 3pm when production peaks.
- Add battery storage: A home battery lets you store excess daytime generation and use it in the evening instead of drawing expensive grid power.
- Choose the right retailer: Feed-in tariffs vary significantly. Use a comparison site like Energy Made Easy to find the best rate.
- Monitor your system: Good inverters like Fronius and Sungrow come with monitoring apps so you can track production and spot issues early.
The STCs (Small-scale Technology Certificates) Discount
Under the Australian Government's Small-scale Renewable Energy Scheme, solar systems receive an upfront discount based on Small-scale Technology Certificates (STCs). This discount is applied at point of sale — you don't need to apply separately.
This incentive is set to phase down incrementally until 2030, so installing now locks in a higher discount.
Is Solar Right for Your Home?
Solar suits most Queensland homes, but ideal candidates typically:
- Have a north, north-east, or north-west facing roof with minimal shading
- Consume more than 15 kWh/day on average
- Have daytime power usage (work from home, family at home during the day)
- Have quarterly bills over $400

A well-sized solar system in Brisbane typically pays for itself in 3–5 years, then generates free electricity for the remaining 20+ years of its life. With electricity prices only moving in one direction, the financial case for solar has never been stronger.
