Solar Power Packages in QLD: Compare Prices

Solar power packages QLD prices

Navigating the world of solar power packages in Queensland can feel overwhelming, but I’m here to break it down for you. The final price you pay depends on the system size, the quality of the components (panels and inverter), and the complexity of the installation.

For most households, solar power packages are bundled by their power output, measured in kilowatts (kW). Here’s a snapshot of what you can expect to pay for a quality, fully installed grid-connect system in Queensland, after the federal government rebate has been applied:

• 3kW System: Typically costs between $3,900 – $4,500. Suitable for smaller households with lower energy consumption.

• 6.6kW System: This is the sweet spot for the average Queensland family. Expect prices to range from $5,200 to $7,300.

• 10kW System: For larger homes with high energy usage (or those planning for an electric vehicle), prices generally fall between $8,000 and $12,000.

If you’re considering going completely off-grid, the prices for off grid solar power packages are substantially higher because they require a much larger solar array and significant battery storage. These systems are highly customised and can start from $25,000 and go well beyond $50,000.

Gigi’s Pro Tip: Don’t just focus on the lowest price for solar panels. The quality of the inverter is just as crucial, as it’s the component most likely to fail. A good quality inverter from a brand like Fronius or Sungrow will ensure your system performs reliably for years.

Compare solar panel prices Queensland

When you start getting quotes, you’ll see a variety of solar panels and prices. I’ve found it helpful to categorise them into tiers based on performance, warranty, and price.

Panel Tier	Brands	Price Guide (per panel)	Best For
Premium	REC, SunPower	$350 – $450+	Homeowners seeking the highest efficiency and longest warranties, especially with limited roof space.
Great Value	Trina, Jinko, Canadian Solar	$230 – $395	The majority of households, offering a fantastic balance of performance, reliability, and cost.
Budget	Various smaller brands	$180 – $250	Those on a very tight budget, but be sure to check warranties and installer reputation carefully.

A common mistake I see homeowners make is getting fixated on the solar power panel prices alone. The installer’s experience and accreditation are paramount. Always choose an installer accredited by Solar Accreditation Australia (SAA) to ensure your system is safe, compliant, and eligible for rebates.

6.6kW solar system cost QLD 2025

The 6.6kW solar system is the most popular size in Queensland for a good reason. It hits the perfect balance for most family homes, generating enough power to significantly reduce bills while being the largest system size you can install with a 5kW inverter, which is often the limit for single-phase grid connections to receive full feed-in tariffs.

In 2025, the average cost of a good quality 6.6kW solar system in Brisbane is around $5,200 to $5,800. With higher-end panels and inverters, this price can climb towards $7,500 or more. This price includes the panels, inverter, mounting equipment, and professional installation, with the federal STC rebate already deducted by the installer.

For those wanting to maximise their solar usage, pairing a 6.6kW system with a battery is a popular option. A full package with a 10kWh to 13.5kWh battery can range from $9,500 to $14,000.

Case Study: A Family in Toowoomba The O’Brien family was hit with a shocking $700 quarterly power bill and decided to act. They installed a 6.6kW Jinko solar panel system and a 10kWh Sungrow battery. The total cost was $16,000, but after the new federal battery rebate, their out-of-pocket expense was around $12,000. Their annual savings are now projected to be over $2,400, giving them a payback period of just 5 years. Now, they mostly just pay the daily grid connection fee.

10kW solar system price Brisbane

For households with larger energy needs—think ducted air conditioning, a pool pump, and maybe an EV charger—a 10kW solar system is an excellent investment. In Brisbane, the average price for a 10kW system in 2025 ranges from approximately $8,000 to $12,000 after the federal rebate.

Key factors influencing the price include:

• Component Quality: Premium panels and inverters will place you at the higher end of that range.

• Installation Complexity: A multi-storey home or a roof with difficult access can increase labour costs.

• Adding a Battery: To become more self-sufficient, adding a battery to a 10kW system is common. A 10-15kWh battery adds another $7,000 to $12,000 to the total cost.

A 10kW system will typically require between 25 to 30 panels, depending on their wattage, so you’ll need a good amount of north-facing roof space to make the most of it.

Best solar companies in Queensland reviews

Choosing the right installer is arguably the most critical step. A great system installed poorly will lead to nothing but headaches. From my research and analysis of customer feedback, here are some of the consistently well-regarded solar companies in Queensland:

• MC Electrical (Brisbane): Known for their high-quality installations and technical expertise. They have a strong reputation for not subcontracting and for their thorough approach to system design.

• Reef Solar & Electrical (Gladstone Region): Praised for their customer-centric approach, focusing on education and transparency. They handle all installations with their own local team.

• Sunlogics Solar & Electrical (Brisbane): A family-owned business with over 15 years of experience. They are highly rated for not using subcontractors and having a perfect 5-star Google Review record from a large customer base.

• Queensland Solar & Lighting (Brisbane): A smaller, tight-knit team that has been operating since 2012. They are noted for looking after their staff, which translates into high-quality workmanship.

When checking reviews, I recommend looking for patterns. Are customers praising the communication, the neatness of the installation, and the after-sales support? These are the hallmarks of a trustworthy company.

Queensland government solar rebates and incentives 2025

The main financial incentive for installing solar in Queensland is the federal government’s Small-scale Renewable Energy Scheme (SRES). This isn’t a direct cash rebate but an upfront discount on your system.

Here’s how it works:

• The scheme provides Small-scale Technology Certificates (STCs) based on your system’s size and your location.

• Your SAA-accredited installer will claim these certificates on your behalf and apply the discount directly to your quote. You only pay the final, lower price.

• For a 6.6kW system in Queensland, this discount is typically between $2,000 and $2,500 in 2025.

Exciting News for Batteries: While the Queensland state battery rebate program has ended, the new federal Cheaper Home Batteries Program starts from July 2025. This scheme is expected to offer a rebate of up to 30% off the cost of a new home battery system. For a Tesla Powerwall 3, this could mean a discount of over $4,700.

Average cost of solar panel installation QLD

It’s important to understand that the prices I’ve quoted for systems above already include the cost of installation. However, if we break it down, the installation and associated electrical work typically account for about 20-30% of the total system cost.

For a standard 6.6kW system, the installation component of the price might be around $1,500 to $2,500. This covers:

• Mounting the panels on your roof.

• Installing the inverter.

• All electrical wiring to connect the system safely to your switchboard and the grid.

• System testing and commissioning.

• Handling the necessary paperwork with your electricity retailer and network provider.

Costs can be higher for non-standard installations, such as those on terracotta tile roofs, multi-storey buildings, or properties requiring significant switchboard upgrades.

Solar feed-in tariffs QLD 2025 comparison

A feed-in tariff (FiT) is the credit you receive from your electricity retailer for any unused solar power you export to the grid.

In Queensland, the situation is split:

• Regional Queensland (Ergon Energy network): There is a regulated minimum FiT, which for the 2025-2026 financial year is set at 8.66 cents per kWh.

• South East Queensland (Energex network): Retailers are free to set their own competitive rates. There is no mandatory minimum.

In SEQ, rates can vary significantly. As of late 2025, some of the best offers from retailers like AGL, Origin, and ENGIE are between 10c and 15c per kWh, but often this higher rate is capped to the first 10-14 kWh exported per day.

Gigi’s Pro Tip: Don’t be lured by a high feed-in tariff alone. Some retailers offer a great FiT but charge much higher rates for the electricity you import from the grid. Always compare the entire plan—usage rates, daily supply charges, and the FiT—to find the best deal for your circumstances.
