Navigating the world of solar and battery storage can feel overwhelming, especially when it comes to the bottom line. I’m often asked, “What’s the real cost of a full solar and battery system in Brisbane?” It’s a great question, because the answer isn’t just a single number; it’s a mix of system size, component quality, installation complexity, and available government rebates.

My goal here is to break it down for you, providing clear, current pricing for Brisbane so you can make a confident decision for your home. We’ll look at the cost of solar panels on their own, the price of popular batteries, and what you can expect to pay for a complete, installed package.

How much do solar systems cost in Brisbane? (panels and inverter only)

First, let’s look at the cost of just the solar panel system—the panels on your roof and the inverter that converts the sun’s energy into usable electricity. The prices you see advertised will almost always have the federal government’s STC incentive already deducted.

Here are the typical price ranges for quality solar systems in Brisbane:

These prices are influenced by the quality of the components. Premium panels from brands like REC or high-end inverters will be at the upper end of the scale, while great value brands like Trina or Jinko panels paired with a Sungrow inverter will be more towards the lower end. From my analysis of dozens of system quotes, both are excellent choices for Brisbane homes.

What is the cost of a solar battery in Brisbane?

Adding a battery allows you to store your excess solar energy generated during the day for use at night, which is the key to slashing your power bills. Battery prices vary by brand and capacity, which is measured in kilowatt-hours (kWh).

For a medium-sized 10-13.5kWh battery, you can expect to pay between $9,000 and $14,000 fully installed. Small batteries around 5kWh might cost between $5,500 and $8,000. Gigi’s Pro Tip: When comparing battery warranties, look for both the ‘cycle life’ rating and the ‘throughput’ (total energy the battery is warranted to deliver). A 10-year warranty is standard, but the cycle and throughput figures tell you how much work the battery is guaranteed to do over that time.

Tesla Powerwall, Sungrow & BYD: a price comparison

These are three of the most popular and trusted battery brands on the Australian market. I’ve broken down their typical installed costs in Brisbane to give you a clearer picture. Note that the new Tesla Powerwall 3 includes an integrated inverter, which can simplify new installations.

Are there any solar battery rebates in Queensland?

Yes, there are significant incentives available that can dramatically reduce the cost of solar and battery systems in Brisbane.

• Federal Government STC Incentive: This is the main “rebate” for solar panels. It’s not a cash-back offer but an upfront discount that is handled by your installer. For a 6.6kW system in Brisbane, this can be worth around $2,000.

• Federal Government Cheaper Home Batteries Program: This is a game-changer for battery affordability. Starting from July 2025, this program provides a rebate of about 30% off the upfront cost of an eligible battery. For a 10kWh battery, this translates to a saving of approximately $3,440.

• Queensland Government Rebates: The popular Queensland Battery Booster Program is currently closed to new applicants as of late 2025. However, the state government has a history of supporting renewables, so it’s always worth checking for new programs.

What are the “hidden” costs of solar and battery installation?

One of the most common unexpected costs is a switchboard upgrade. Modern solar and battery systems require up-to-date switchboards with modern safety switches. If your home is older, your board may need an upgrade to be compliant and safe.

In Brisbane, a standard switchboard upgrade typically costs between $800 and $1,500. In more complex cases, particularly for larger homes or those needing significant rewiring, the cost can range from $1,400 to $2,400. It’s crucial that this work is done by a licensed electrician and that your installer inspects your switchboard as part of the initial quote.

Putting it all together: fully installed solar and battery system prices in Brisbane

Now, let’s combine these costs to see the total price for a full solar and battery package. These prices factor in panels, an inverter, a battery, and standard installation, but before the new federal battery rebate is applied.

• 6.6kW Solar and 10kWh Battery Package: Expect to pay between $12,500 and $21,500. A package deal with an iStore 10kWh battery can be found from around $11,500.

• 10kW Solar and 13.5kWh Battery System: This larger setup will typically cost between $19,000 and $22,000.

Case Study: A Family in Chermside The O’Brien family was hit with quarterly power bills often exceeding $700 due to air conditioning and a pool pump. They installed a 6.6kW system with Trina panels and a 10kWh Sungrow battery for a total of $14,500. After applying the new federal battery rebate, their upfront cost was closer to $11,000. Their annual savings are now projected to be over $2,400, giving them a payback period of under 5 years, and their last summer bill was just the daily grid connection fee.

What is the average cost of a full solar and battery system in Brisbane after rebates?

After factoring in all available rebates, a Brisbane homeowner can get a high-quality, fully installed solar and battery system for a significantly reduced price.

For the most common setup—a 6.6kW solar system with a 10kWh battery—the average cost after the STC incentive and the new federal battery rebate would fall into the $9,000 to $15,000 range. This makes investing in energy independence more accessible than ever.

Choosing the right system is a big decision, but with the right information, it doesn’t have to be a stressful one. By understanding the costs and the fantastic rebates available, you can find a solution that fits your budget and sets your family up for years of energy savings.
