Getting quotes for solar panels and a battery can feel like you’re suddenly drowning in kilowatts, warranties, and brand names you’ve never heard of. I get it. When I first started this journey, the quotes felt confusing, and I was worried about choosing the wrong system or, worse, the wrong installer.

This guide is here to change that. We’re going to walk through how to compare solar and battery quotes in Brisbane, breaking down the costs, decoding the jargon, and flagging exactly what you need to look for to make a confident choice for your home.

How to compare solar and battery quotes in Brisbane

When the quotes land in your inbox, it’s tempting to just scan for the lowest number. But value in the solar world isn’t just about the upfront price; it’s about performance, safety, and support over the next 10 to 25 years.

A quality quote is more than a price; it’s a detailed proposal. It should be computer-generated and show exactly where the panels will go on your roof, along with an estimate of how much energy the system will produce. It needs a clear breakdown of all costs, from the panels and battery down to the mounting brackets and any potential switchboard upgrades.

Here’s a simple checklist to use when you have multiple quotes side-by-side:

• System components: Does the quote clearly list the brand and exact model number for the solar panels, the inverter, and the battery? This is non-negotiable. Without it, you can’t verify the quality or the warranty terms.
• Warranties: Check for three key warranties: a product warranty (minimum 10-15 years for panels, 5-10 for inverters, and 10 for batteries), a performance warranty for the panels (usually 25 years), and a workmanship warranty from the installer (at least 5 years).
• Accreditation: The quote should confirm the installer is SAA (Solar Accreditation Australia) accredited. Don’t be shy about asking for their accreditation number. This is your proof that they are up-to-date with Australian standards and that your system will be eligible for rebates.
• The fine print: Look for details on who is responsible for each part of the process and whether there are any hidden costs, like equipment hire.

The average cost of a 10kW solar system with a battery in Brisbane

Okay, let’s talk numbers. For a large household in Brisbane with high energy usage, a 10kW solar system is a popular choice. When you pair this with a battery, you’re setting yourself up for some serious energy independence.

As of October 2025, you can expect the following price ranges in Brisbane:

• A 10kW solar system (panels and inverter only): This typically costs between $8,000 and $12,000 after the federal STC rebate is applied.
• A 10kWh battery (added to a system): A quality 10kWh battery, like a Sungrow or BYD, will cost between $9,000 and $14,000 fully installed. A premium option like the Tesla Powerwall 3 (13.5kWh) sits higher, around $13,000 to $17,500.
• A combined 10kW solar system with a 10-13kWh battery: For a complete package deal, expect a price range of $17,000 to $25,000+. A good quality, professionally installed 10kW system with a mid-size battery is often quoted between $17,500 and $22,000 before any new rebates.

These prices include the federal Small-scale Technology Certificate (STC) rebate, which is an upfront discount applied by your installer.

The ultimate solar quotes battery comparison: Tesla Powerwall vs Sungrow SBR

Two of the most common names you’ll see on battery quotes are Tesla and Sungrow. They are both excellent choices, but they cater to slightly different priorities.

• Tesla Powerwall 3: Think of it as the premium, all-in-one solution. The Powerwall 3 has a usable capacity of 13.5kWh and includes an integrated solar inverter, which is perfect for new installations. It’s known for its sleek design and powerful software. In Brisbane, expect a fully installed Powerwall 3 to cost between $13,000 and $17,500.
• Sungrow SBR Battery: Sungrow has become a favourite among installers for its reliability and excellent value. It’s a modular system, meaning you can stack batteries to get the capacity you need (from 9.6kWh to 25.6kWh). This makes it flexible. For a comparable size, a 12.8kWh Sungrow SBR system typically costs around $9,500 to $10,200 installed in Brisbane, making it a significantly more affordable option.

Gigi’s pro tip: If you already have solar panels and are adding a battery, the Sungrow can be a very cost-effective choice. If you’re starting from scratch and want a seamless, integrated system with top-tier software, the Powerwall 3 is a strong contender.

Finding the best solar and battery installers in Brisbane

The person who installs your system is just as important as the system itself. A great installer ensures safety, compliance, and performance, and will be there to support you for years to come. Based on consistently high customer reviews and industry recognition for 2025, here are a few Brisbane-based installers that homeowners speak highly of:

• Halcol Energy: As one of the largest and longest-running installers in South-East Queensland, Halcol has a strong reputation backed by thousands of installations. Customers frequently praise their professionalism, from the sales process through to the installation crew. They are noted for handling complex jobs and having expertise across a wide range of top brands like Sungrow, Tesla, and Fronius.
• Symons Energy: Often praised for their exceptional, personalised customer service, led by owner Kosta. Reviews consistently highlight their competitive pricing, honesty, and high-quality workmanship. Many customers mention Kosta’s deep knowledge and willingness to answer every question, making them feel confident in their investment.
• MC Electrical: Based in Eagle Farm, MC Electrical is known for its focus on premium products and high-end technical expertise. The founder, Mark Cavanagh, is well-respected in the industry for his technical blog where he tests and reviews solar equipment, giving customers extra peace of mind. They are often recommended for those seeking a top-quality, long-lasting system.

Watch-out: Always choose an installer who uses their own in-house, SAA-accredited team rather than unknown subcontractors. This ensures accountability for the quality of the installation.

Queensland government solar and battery rebates in 2025

Navigating rebates can be tricky, but in Queensland, the incentives are designed to make solar and batteries more affordable. As of October 2025, here’s what you need to know:

• Federal STC Scheme: This is the main financial incentive. It’s not a cash rebate but an upfront discount on the cost of your system, which can reduce the price by thousands. Every quote you receive from a legitimate installer will already have the STC discount included.
• Federal Cheaper Home Batteries Program: Starting from July 1, 2025, this program is a game-changer. It offers a significant rebate on new battery installations. The rebate is calculated per kilowatt-hour (kWh) of battery capacity and could slash the upfront cost by around $3,000 to $4,000 for a typical 10-13kWh battery.
• Queensland State Rebates: The popular Queensland Government “Battery Booster Program” is currently closed to new applicants. However, it’s worth checking for new rounds, as the state government often introduces new programs. A new “Supercharged Solar for Renters Program” has also been introduced to help landlords install solar, providing rebates of up to $3,500.

Solar panel and battery package deals in Brisbane

Many installers offer bundled packages, which can be a convenient and cost-effective way to go solar. These deals typically pair a popular system size, like 6.6kW of panels, with a 10kWh battery.

For example, you might see offers like:

• A 6.6kW solar system with a 10kWh battery fully installed from around $9,990.
• An 11kW solar system with a 10kWh iStore battery starting from $14,990.

These packages often feature quality Tier 1 panels (like Jinko, Risen or Trina) and a reliable hybrid inverter from a brand like Sungrow. The key is to ensure the package includes quality components with strong warranties and is installed by a trusted, SAA-accredited professional.

Getting solar and a battery is a big decision, but it doesn’t have to be a stressful one. By focusing on quality components, comprehensive warranties, and a highly-rated installer, you can be confident you’re making a smart investment in your home’s energy future.
