Finding the best solar installers in Brisbane: Reviews and recommendations

The single most important decision you’ll make is choosing a quality installer. A great system installed poorly will only lead to headaches. Here’s what I look for:

• Solar Accreditation Australia (SAA) approval: This is non-negotiable. SAA accreditation has superseded the old Clean Energy Council (CEC) scheme for installers. Always check your chosen installer is SAA accredited. This ensures they are up-to-date with the latest safety standards and industry best practices.
• Strong local reputation: Look for companies with a long history in Brisbane and positive, detailed customer reviews. Companies like MC Electrical, G-Solar & Electrical, and Reef Solar & Electrical have received positive feedback for their service and quality workmanship. Many top-tier local installers, such as Optimum Solar Energy and Sunlogics Solar & Electrical, are owner-operated, meaning the person quoting the job often has a direct stake in its quality.
• In-house teams vs. subcontractors: Ask if the company uses its own dedicated team of installers or if they subcontract the work. In-house teams often provide more consistent quality and accountability.
• Transparent and educational approach: A good installer will take the time to explain your options without high-pressure sales tactics. They should assess your energy consumption and design a system tailored to your needs.

Gigi’s pro tip: Be wary of “too good to be true” offers. Extremely low prices often hide subpar components, inexperienced installers, or poor after-sales support. Longevity in the business is a good sign that a company will be around to honour its warranties.

Average cost of solar panels in Brisbane for 2025

Solar prices have thankfully become more affordable over the last decade. In Brisbane, the final price of your system will depend on the quality of the components and the complexity of the installation.

Here’s a realistic breakdown of what you can expect to pay for a quality installation in 2025, after the federal rebate has been applied:

• For a 6.6kW solar system: This is the most popular size for Australian homes and typically costs between $5,000 and $8,500 in Brisbane. On average, you might see prices around $5,280 to $6,378.
• For a 10kW solar system: Ideal for larger homes with higher energy usage, a 10kW system generally costs between $8,000 and $12,500. The average price in Brisbane sits around $8,190 to $9,610.

These prices are a guide for good quality systems. Premium panels and inverters can increase the cost by 20-30%.

Understanding Queensland’s government solar rebates in 2025

The main financial incentive available to Brisbane residents is the federal government’s Small-scale Renewable Energy Scheme (SRES).

• How it works: Often called the “solar rebate,” this scheme provides a point-of-sale discount on the upfront cost of your system. Your installer handles all the paperwork for this. The discount comes from creating Small-scale Technology Certificates (STCs), and the total value depends on your system size and location (Brisbane is in Zone 3). For a 6.6kW system, this rebate can be worth over $2,100.
• Is it ending? The SRES is being phased out, with the value of STCs reducing slightly each year until the scheme ends in 2030.

Cost reality check: Advertised prices for solar systems almost always have the STC rebate already factored in.

Additionally, while Queensland’s Battery Booster program has closed, a new federal solar battery rebate is expected to be introduced in July 2025, offering further savings for those wanting to add storage. Keep an eye out for details on eligibility and how to apply.

What to look for in a solar quote: A detailed checklist

A good solar quote is more than just a price. It’s a comprehensive document that should give you complete clarity on what you’re buying. When you compare solar quotes, make sure they are “apples-for-apples” and include the following:

• System components: The quote must list the exact brand, model, and quantity of the solar panels and the inverter. It should also specify the brand of the mounting system (racking).
• Warranties: Panel Product Warranty: This covers defects in the panel itself. Look for a minimum of 10-15 years.
• Warranties: Panel Performance Warranty: This guarantees a certain level of output over 25 years.
• Warranties: Inverter Warranty: A good inverter should have a warranty of at least 10 years.
• Installation warranty: This is crucial. It covers the workmanship of the installation itself. Do not accept less than a 5-year warranty from the installation company (not a subcontractor).
• Itemised costs: The quote should clearly show the gross price, the STC rebate discount, and the final, total price including GST. Any extra charges for things like a difficult roof, a two-storey house, or a switchboard upgrade must be listed.
• Performance estimate: The installer should provide a realistic estimate of how much energy (in kWh) the system is expected to produce annually. This helps you calculate your potential savings.
• Company details: The quote should include the installer’s SAA accreditation details, ABN, and contact information.
