If you’re already enjoying the benefits of solar energy in Brisbane, you’re on the right track. But did you know you could boost your savings even more by adding a 10kWh battery to your existing or new solar system?
Whether you’ve installed a 6.6kW, 10.5kW, or 13kW solar system, integrating a battery can dramatically increase your return on investment, reduce your electricity bills, and provide energy independence.
In this blog , we’ll explore how a 10kWh battery can work with different system sizes and why it might be the smartest addition to your energy setup.
Why Add a Battery to Your Existing or New Solar System?
Many Brisbane households with solar systems find themselves exporting excess power to the grid during the day—only to buy it back at much higher prices during peak hours. This mismatch can limit the real value of your solar investment.
A 10kWh battery helps solve this problem.
The Problem: Selling Cheap, Buying Expensive
- Feed-in tariffs in Queensland are lower than peak electricity rates
- During the day, you often send power to the grid for 5–10 cents per kWh
- At night, you’re paying 25–35 cents per kWh to use electricity from the grid
The Solution: Store and Use Your Own Power
By adding a battery, you can store surplus solar energy during the day and use it in the evening, avoiding costly electricity rates. This not only cuts your bills but also boosts your self-sufficiency.
Benefits of Battery Integration
- Use more of your own solar energy
- Minimise reliance on the grid
- Save more during peak rate periods
- Gain blackout protection with a hybrid inverter
- Monitor and manage energy in real-time via apps like iSolarCloud
6.6kW Solar System + 10kWh Battery: Small Setup, Big Impact
This setup is ideal for smaller households or those with lower energy usage who still want to maximise their savings.
Why It Works
- A 6.6kW solar system can generate enough energy on a typical Brisbane day to fully charge a 10kWh battery
- That stored energy can then be used to power evening lighting, appliances, or even air conditioning
- You reduce how much energy you buy from the grid—saving money every month
This system is popular for couples, retirees, or energy-efficient homes.

10.5kW Solar System + 10kWh Battery: Balance of Power
Mid-sized families or people working from home often find that this setup strikes the perfect balance between production and storage.
Key Benefits
- Charges your 10kWh battery quickly
- Leaves room for appliance use during the day (washer, dryer, AC, etc.)
- Better electricity bill reduction due to greater solar coverage
If your home has higher daytime and night-time energy needs, this configuration provides both flexibility and savings.

13kW Solar System + 10kWh Battery: Built for Bigger Homes
Have a large family, pool, home office, or electric vehicle? A 13kW solar system with a 10kWh battery delivers serious power.
Perfect For
- Families with high energy usage
- Homes with multiple air conditioners or large appliances
- EV charging during the day with leftover solar energy
- Battery upgrades in the future—scalable and flexible
In Brisbane’s sunshine-rich environment, this setup often means the battery is charged before midday, and the remaining power runs the house or EV.

Common Benefits Across All Sizes
No matter which solar system size you choose, pairing it with a 10kWh battery unlocks a range of benefits.
Across All Configurations
- Night-time grid independence
- Blackout protection with hybrid inverter systems
- Smart energy use equals faster return on investment
- Remote monitoring with solar tracking apps
- Future readiness with EV support or battery scaling
These benefits are especially useful during Brisbane’s summer months when air conditioning can spike energy costs.
What About Rebates & Incentives?
The Queensland and federal governments offer various incentives that can reduce the upfront cost of battery systems.
Available Support May Include
- Small-scale Technology Certificates (STCs) for eligible systems
- Battery-specific rebate programs (when available in QLD)
- Feed-in tariff opportunities with certain retailers
Your solar installer should help you claim these incentives. Quick Solar supports Brisbane households through the process—from application to approval—so you don’t miss out.
Real Savings You Can Expect
Let’s look at some estimated savings you could enjoy by pairing your solar system with a 10kWh battery:
| System Size | Average Daily Usage Offset | Monthly Savings (Est.) | Estimated Payback Period |
| 6.6kW + 10kWh | 60–70% | $180–$220 | 6–7 years |
| 10.5kW + 10kWh | 75–85% | $250–$320 | 5–6 years |
| 13kW + 10kWh | 85–95% | $320–$400 | 5 years |
Actual figures will vary based on usage patterns, electricity rates, and your location in Brisbane. But in most cases, you’ll see a noticeable drop in your power bill within the first month.
Is a 10kWh Battery Right for You?
Adding a battery isn’t always necessary—but for many Brisbane households, it makes financial and practical sense.

- You export more solar than you use during the day
- You consume most electricity after sunset
- You’re planning to buy an EV or heat pump system
- You want energy independence and backup power
- You live in an area prone to blackouts or grid issues
Quick Battery Readiness Checklist
- You already have a solar system (or are planning to install one)
- You want to reduce your power bills further
- You use electricity in the evenings
- You’re thinking long-term about home energy use
