How much do solar panels cost?

Most people invest in solar panels to lower their electricity bill, gain energy independence or support a more sustainable future. It’s important to be clear on your objectives before you talk to a retailer or installer because this will inform the cost and payback of your solar PV system. Make sure you ask the right questions of your retailer and installer to help you save time and money, and so you get the full benefits of your investment in the long run.

The total cost of your solar PV system is made up of the system size, the quality of components, government rebates, the state you live in and your retailer. There are initial costs and rebates to consider as well as ongoing maintenance costs and feed-in tariffs.

Keeping this in mind, we can provide you with a rough guide that you can use when researching solar companies.

Typically solar PV systems are made up of:

  • solar panels
  • an inverter
  • a customer interface (online portal or platform)

The cost of installing a solar power system will vary depending on the number of panels and the toal electricity output required. The quality of components (panels and inverter) being installed will also impact the pricing of solar panels.

A small solar set up with PV system made up of 12 solar panels and a 3kW output will start around $3,500. A larger setup, between 28-40 panels producing 10kW can cost up to $15,000.

When it comes to solar power, there’s no one size fits all. To ensure you get the right solar system for your property we recommend getting a quote from at least 3 solar installers. This way you can ensure you get the best price possible.



Both federal and state governments have incentives to help bring down the cost of your solar installation.

The small-scale renewabel energy scheme (STCs) is an Australian government incentive as part of the Renewable Energy Target scheme to reduce the cost associated with installing solar power and other renewable energy sources
