The Best Solar Panels and Installers in Brisbane

Updated 22 March 2023


  • Installing solar panels can boost your property value and make your home more attractive to environmentally-conscious buyers. However, you’ll need a north-facing roof with little to no shade to ensure maximum efficiency.
  • Regulation is relaxed; you’ll only need a building permit to install a solar system if your home or building is a registered heritage building.
  • Government data suggests 10% of Australian energy, with solar making up around 25% of the share. However, in mid 2022 the Queensland Government ended its solar rebate and loans program meaning there is no financial support currently on offer for anyone looking to install solar panels.
  • Our guide looks at the costs involved, how effective solar panels are, questions to ask upfront, frequently asked questions and a list of trusted Brisbane solar panel retailers and installers.

Solar Panels Brisbane Costs

How Much do Solar Panels Cost?

Several factors can impact the price of a solar panel system for your home. One of the primary considerations is the number of panels required, which depends on your energy consumption and the desired system capacity. The efficiency of your solar panels is also crucial, as it can influence the amount of electricity generated in relation to the available sunlight.

The desired kilowatts per hour (kWh) output of your system is another factor that will affect the price. A larger system with higher kWh output will generally be more expensive but may provide greater long-term savings on electricity bills.

Investing in additional components, such as a solar battery, solar optimiser, or solar inverter, can also influence the overall cost. Solar batteries store excess energy for use when the sun isn’t shining, while solar optimisers and inverters help maximise your solar system’s efficiency and performance. The type and quality of the inverter you choose can also impact the cost.

In some cases, you may need to install a new meter to measure the electricity generated by your solar panels; the cost of this will be factored into the overall price.

Know This: The amount of sunlight your location receives will influence the system’s efficiency and, ultimately, its cost-effectiveness.

How much do solar panels save in electricity costs?

Investing in solar panels is an environmentally conscious upgrade that will pay itself back within 4 to 8 years on average. One of your first decisions is how many kilowatts per hour your panels will be. The more kWh, the more your panels will cost upfront. 

A general guideline is as follows, but this varies greatly on your individual and time-of-day energy usage: 

  • 5–10kWh will save 30% on energy costs
  • 11–15kWh will save 48%
  • 21–25kWh will save 66%
  • 31–40kWh will save up to 82%

Panel and installation prices

Keep in mind that due to the fluctuating global market prices for solar panels, the prices below fluctuate $1,000 more per installation. The prices below are for a family of four (or fewer) living in a home of up to 230 square metres with average energy usage. The more panels you install, the more kilowatts per hour. Most homeowners install systems that are between 4 and 6 kilowatts per hour. 

Ensure the price you are quoted includes installation. 

  • 4kW and approximately 11 panels—$4,000 to $6,000
  • 5kW and approximately 14 panels—$4,500 to $8,000
  • 6kW and approximately 18 panels—$5,500 to $9,000
  • 7kW and approximately 19 panels—$6,500 to $10,000
  • 8kW and approximately 22 panels—$7,500 to $11,000
  • 10kW and approximately 27 panels—$8,000 to $13,000
  • Solar meter installation—$65 to $650 

Solar battery, optimiser, and inverter prices

You may want to invest in a battery, inverter, dual battery-inverter, and optimiser to maximise your panels. This will add at least 20% to your quoted price. However, the larger your battery’s storage capacity, the more you pay. Expect to pay $2,000 for a simple battery and $10,000+ for multi-functionality. Inverters last between 15 and 20 years. Most solar loans include the entire solar system, or you can apply for a secondary battery/inverter/optimiser loan later. 

  • A solar battery stores excess energy you can use as needed or when the sun isn’t shining as bright. 
  • Smart solar optimisers increase energy output by tracking each module’s maximum power point (MPPT). 
  • Standalone solar panel inverters provide extra power during times of heavy electricity usage. 
  • Synchronous inverters feed excess electricity into the grid so you can get paid your Feed-in-Tariffs. 
  • Multi-function inverters can provide extra power during times of heavy electricity usage and send excess electricity back to the grid as needed. 

Ongoing maintenance

Solar systems require maintenance every five years, costing between $600 and $800. If damaged, most solar systems are covered by your homeowner’s insurance, but be sure to double-check. 

How can I get the best price?

  1. Compare quotes from local installers. 
  2. Ask if panel prices are higher than usual, and have the company call you when prices drop.
  3. Keep your eye out for installer sales and discounts. 
  4. Do the math to calculate the short and long-term benefits of FiTs (selling power into the grid) and rebates. 
  5. If you are a business owner with commercial panels, let your accountant know, as you may qualify for a tax deduction.

Can I get government rebates?

Queensland’s Small-Scale Renewable Energy Scheme (SRES) offers some financial incentives but the criteria is strict:

  1. All systems must be less than 100kW in size.
  2. Clean Energy Council-accredited installer must install them 
  3. Your panels and inverters must be approved for use in Australia by the Clean Energy Council. 

The rebate is referred to as the Small-Scale Technology Certificates (STCs). It’s not a traditional rebate, as you aren’t reimbursed – a qualified subsidy directly pays the installer the difference. 

The STC discount is typically between 20% to 33% of the quoted price and varies by factors such as:

  • Panel size
  • Panel location
  • Initial price
  • Market conditions 
  • Deeming period
  • State/zone STC rate 

What can I earn from selling solar power into the grid? 

Queensland law allows you to be credited, and how much you receive depends on the power company you’re with. This guide has the latest Feed-in Tariffs.Are Solar Panels Cost-Effective in Brisbane?

Are Solar Panels Cost-Effective in Brisbane?

In most installations there is a positive return on investment. Brisbane has abundant sunshine and supportive government policies for renewable energy. However, determining the cost-effectiveness of solar panels for a specific situation depends on several factors which must be considered:

  1. Sunshine hours: Brisbane receives an average of around 5.2 peak sun hours per day, which is favourable for solar power generation and some of the highest in metro Australia.
  2. Solar system size: The size of your solar system will affect both the upfront cost and the amount of energy produced. Common residential solar systems in Australia range from 3kW to 10kW, depending on your energy needs and budget.
  3. Solar panel efficiency: Higher efficiency panels produce more electricity per unit area but can also be more expensive. For this reason, you’ll need to find a balance between panel efficiency and cost.
  4. Installation costs: The cost of installing solar panels can vary depending on factors such as the type of roof, system size, and installer fees. However, installation costs have generally decreased as the solar market has matured.
  5. Feed-in tariffs: When your solar system generates more electricity than you consume, you can return the excess power to the grid. The rate you receive, called a feed-in tariff, varies by electricity retailer. A higher feed-in tariff can improve the cost-effectiveness of your solar system.
  6. Electricity prices: Higher electricity prices make solar panels more cost-effective because they offset a significant portion of your electricity bill. In Brisbane, electricity prices tend to be relatively high, which can make solar panels more attractive.
  7. Maintenance and lifespan: Solar panels typically have a long lifespan (25+ years) but may require occasional maintenance or replacement of components like inverters. Consider these costs when evaluating cost-effectiveness.

Overall, these factors will influence the payback period (the time it takes for the energy savings to equal the system’s upfront cost). Solar panels are generally considered cost-effective if the payback period is reasonable (e.g., within 5-10 years).Solar Panels Brisbane Questions to Ask Upfront

Questions to Ask Before Hiring a Solar Panel Installer 

Do they have a solar calculator to help you determine your energy needs and loan qualifications?

A solar calculator can help estimate the size of the solar system required based on your energy consumption, location, and other factors. Ensure the installer provides a solar calculator or can assist you in determining your energy needs.

Financing a solar system can be a significant investment; ask if the installer provides a calculator or resources to help you determine your eligibility for loans or financing options.

Do they have a structural engineer they can refer you to?

Installing solar panels may require structural modifications or assessments of your property. Ensuring your roof or installation site can support the solar system is essential. Ask if the installer can refer you to a structural engineer or if they have one on their team.

Do they have a roofing company they can refer you to?

Solar panel installation may require working with your roof, including repairs, upgrades, or reinforcements. Check if the installer partners with a reputable roofing company or can refer you to one.

What is their experience with local permitting and regulations?

Solar panel installation often involves obtaining permits and complying with local regulations. Ensure the installer is familiar with these processes in your area.

What warranties do they offer for their products and workmanship?

Inquire about the warranties provided for the solar panels, inverters, and other components and their workmanship. A reputable installer should offer warranties that protect your investment.

Do they provide ongoing support and maintenance services?

Regular maintenance and monitoring are crucial to ensure your solar system’s optimal performance. Ask if the installer offers support and maintenance services after the installation.Solar Panels Brisbane Frequently Asked Questions

Frequently Asked Questions

How quickly will my solar panels pay for themselves?

The payback period is essential to understand to measure the return on your investment, e.g. upfront costs installing solar panels. How long the payback period is depends on various factors, including how many kilowatts per hour your system generates, your energy usage if you have a solar battery, and if you are utilising the net Feed-in-Tariff (FiT) which is the standard for Queensland .Expect to break even between 4 and 8 years.

How many solar panels do I need?

You will unlikely need ten or less panels to power your home. This will provide 4kW for a standard-sized home. However, most homeowners opt for 5kW or 6kW, which is between 14 and 18 panels.

How much does a solar panel system cost in Brisbane?

The cost of a solar panel system in Brisbane varies depending on the system size, panel quality, and installation expenses. On average, a 5kW to 6kW solar system may cost between $5,000 and $9,000, including installation. However, government incentives, when available, can help reduce the upfront cost.

How do I choose a solar panel installer?

Select a solar panel installer with Clean Energy Council accreditation, experience in the industry, and a good reputation for customer service. Ask for references and testimonials, inquire about warranties, and discuss their experience with local permitting and regulations. Ensure they can help you with solar calculations and support any necessary structural engineering or roofing work.

What maintenance is required for solar panels?

Solar panels require minimal maintenance, but regular cleaning and inspections are essential to ensure optimal performance. Remove debris and dirt from the panels and check for damage or wear. The system’s inverter may also need replacement after 10-15 years. Consider engaging a professional solar maintenance service for thorough inspections and cleaning.

Is it worth installing a solar battery?

Solar batteries store excess solar energy generated during the day for use during the night or when solar production is low. Installing a solar battery may improve your energy independence and help reduce your reliance on grid electricity. However, solar batteries can be expensive, and their cost-effectiveness depends on factors such as electricity prices, battery capacity, and the available Feed-in-Tariff. Consider your energy consumption patterns and potential savings before investing in a solar battery.
