Here's everything you need to know about installing solar power in Cairns:
How much power does solar produce in Cairns?
Cairns experiences higher solar energy exposure, during the summer months. It is due to extended daylight hours. While winter production naturally decreases, South Australia's overall sunshine hours still enable significant solar power generation throughout the year.
As a reference point, a typical 5kW north-facing system in a clear area can generate an average of 21kWh per day, translating to approximately 8,238kWh annually. Similarly, a 10kW system could produce around 43kWh daily and achieve an annual output of 16,477kWh.
How much do solar systems cost in Cairns?
The cost of solar systems varies based on your energy needs, usage, and roof size. Fortunately, high-quality panels are now more affordable, offering a solid return on investment over time.
Here’s what affects the cost:
Panels: High-quality panels may cost more but provide superior performance and longevity.
Inverters: These convert solar power into usable electricity. Reliable inverters last longer and can save on replacement costs.
Monitoring: Advanced systems allow detailed tracking of your energy production and usage.
A typical 5kW system in Cairns ranges from $5,000 to $8,000 and can save about $1,800 per year. A 10kW system may cost $7,000 to $13,000 and could save approximately $3,000 annually. Additional costs may apply for complex installations or challenging roof conditions.
What direction should my solar panels face in Cairns?
The direction of your solar panels affects their energy output. Panels facing north typically capture the most sunlight throughout the year, which is especially beneficial in winter. For roofs that don’t face north, east-facing panels generate power earlier in the day, while west-facing panels are better for afternoon energy needs. Adjusting the tilt of solar panels on flat roofs can improve energy capture and prevent water pooling, but panels on angled roofs can follow the existing angle of the roof.
Enphase microinverters can be another efficiency booster. Splitting your arrays into smaller sections can ensure consistent power output throughout the day and avoid midday surges. This strategic placement based on your usage patterns (e.g., east for mornings) lets you use most solar power during peak hours, increasing your savings, particularly if your electricity rates fluctuate.
How many solar panels do I need in Cairns?
The size of your solar system depends on your goals. Are you looking for a fast payback on your system? Or do you want to reduce your energy bills? If you’re looking for a quick return on investment, your system should cover your daytime energy use.
Panels ideally should face north or northwest to capture the most sunlight and increase savings during high electricity rate periods. Consider your local weather, roof orientation, and available space when deciding on the system size and placement. This approach ensures you get the most from your solar investment.

What are the warranties available for solar in Cairns?
Unfortunately, hundreds of solar companies have gone out of business since 2011, leaving homeowners with inoperable systems and worthless warranties. To avoid future issues, look for panels with a 25-year performance and 10-12-year product warranty. Choosing a reputable installer with a proven track record ensures long-term benefits and reduces the risk of complications if your installer goes out of business.
What is the rooftop solar application process in Cairns?
Before your solar panels are installed, we'll ensure that all local council regulations are met. Don’t worry—we’ll help with permits and approvals. After installation, an inspector may verify that everything is working safely.
Once everything is approved, we’ll also handle coordinating with your electricity provider to set up your meter and manage all the necessary paperwork, ensuring your system is legal, safe, and ready to generate clean energy.
Are there risks with installing cheap solar in Cairns?
Yes, cheap solar systems are too risky. Opting for cheaper solar panels can lead to problems like poor performance or premature failure, resulting in repair costs and lost savings. Low-quality panels often suffer from issues like hotspots and browning, which can affect performance and safety. Investing in high-quality panels is more reliable and cost-effective in the long run.
Who are the electricity network operators in Cairns?
In Cairns, Ergon Energy is likely your electricity network operator. Queensland has two main zones: Energex for the southeast and Ergon Energy for regional areas, which includes Cairns.
What are the battery storage options for Cairns?
Battery storage has revolutionised the solar industry, changing the way we use renewable energy to power our daily lives. Installing a battery is particularly beneficial to homes in more rural or remote areas as your reliance on the grid is reduced, this increased energy independence not only saves you money but if your solar battery also has a blackout protection mode configured, then you can remain self-sufficient during outages.
But what are the options for Cairns? Today, there are a number of solar storage solutions available on the market. A reputable solar installer like 1KOMMA5° will help you to choose a battery that matches your energy needs, taking into consideration the elements of battery storage that are most valuable to your property or personal situation.
Is solar power worth it in Cairns?
In short, absolutely! The location of Cairns makes it the ideal place to install solar power. Due to the subtropical climate, on average this region experiences higher sunshine hours throughout the day, making Cairns one of the best places to install solar. Making the most of this locational advantage is a smart investment in your future and your home.
