Compare Solar Panels in Cairns

The solar panels your solar installer selects will be chosen based on your personal preference, energy needs, and budget. Most solar installers will use their preferred solar panel manufacturer, which is why getting multiple quotes is important if the brand of solar panel is an important factor for you.

Energy Matters recommends that you select Tier 1 solar panel manufacturers for your solar panels. Tier 1 manufacturers produce solar panels of a higher quality and they will be more likely to honour their manufacturer’s warranty compared to lower-tiered manufacturers. Every year, Bloomberg New Energy Finance releases their Tier 1 PV Module Manufacturer list.

In addition, Energy Matters has partnered with trusted solar panel manufacturers that we are proud to recommend to our customers. These recommended manufacturers are:

REC Solar
LONGi Solar
Powerwave solar
Hyundai Energy Solutions
Jinko Solar
Axitec Solar
Suntech
SunPower Maxeon

Whether you know which panels you want to install on your home or business, or you’d rather discuss your options, we recommend that you begin your solar journey by getting up to 3 FREE, no-obligation quotes. Our network of trusted, local installers will provide personalised quotes for a system that will meet your current and future needs.

The good news is that solar panel prices have reduced significantly over the last 10 years. When determining the number of solar panels you need to install for your Cairns property, you should consider your roof and the amount your local electricity network will allow you to install. 

For most homes in QLD, the solar system size is 6.6 kW of panels with a 5 kW inverter. You can install up to 33 per cent more panels than the inverter is rated at. 

Additionally, if you use a lot of electricity, or you are thinking of adding an electric vehicle or battery to the property in the coming years, consider installing a bigger solar system. 

As previously stated, your solar installer will factor in your current and future needs. We also recommend sizing up, where possible. Your future electricity needs will undoubtedly increase with electrification and a move to Electric Vehicles. Adding solar panels, or completely upgrading your solar PV system in the future, are expenses you wish to avoid. For this reason, sizing up is recommended.

Solar Rebates and Incentives in Cairns

With more sunshine than many other places in Australia, you can get up-front discounts thanks to the federal government. In Cairns, QLD, homeowners can expect a discount on the cost of solar system via the Federal Government’s STC program

Small-Scale Technology Certificates (STCs

The discount comes from the Small-Scale Technology Certificates (STCs). When a homeowner installs a solar power system, they will be entitled to get a specific number of STCs based on the size and location of solar installation. 

Every STC has monetary value, and these certificates’ total value will equate to your deduction. In turn, the more solar panels you have, the bigger the deduction will be. 

Your solar installer in Cairns will handle the application for the STCs on your behalf and apply the STC’s value as a discount at the point of sale. 

For example, if you have a 6.6 kW system size, you will get approximately $3,600 of STCs. 

Feed-in Tariff (FiT)

Feed-in Tariff (FiT) is another solar incentive available to homeowners connected to the grid The FiT is the amount you get paid by your energy retailer in Cairns for the excess energy your solar panels export back into the grid. 

During the day, it’s common for a solar panel system to generate more power than what is being used in the home. So, if your system is connected to the grid, the energy that you don’t use will be sent back to the grid, and your energy retailer will pay you a fixed amount per kWh of energy. You can find the most current FiTs available here



The Right Solar System in Cairns

To find the right solar system for your Cairns property, you need to consider several factors: 

  • The amount of power you use during the day
  • The roof orientation
  • Shading
  • Roof space

For example, if you have a 5kW solar system in Cairns, your average daily output will be around 21 kWh, with an expected return on investment in three to five years.
