In several regions around Cairns solar panel pentration has exceeded 30% as can be seen in above image and data sourced from the Australian Photovoltaic Institute. This article helps to explain why so many people are taking advantage of solar power.
Why is Cairns a good place for solar power?
Lots of sunshine means lots of potential for Cairns homes and businesses to harness solar power
Cairns receives an an average of around 5.3 hours of full sun per day, making it one Australia’s sunnier cities, as well as one of the best places to install solar PV. To calculate how much a solar system will produce you need to multiply the peak sun hours by the system DC (solar panel) capacity and reduce by a efficiency factor typically around 80%. We have done the calulations for you below with some popular system sizes:
|Solar System Size||Average Output (slightly higher in summer, lower in winter)|
|3kW Solar System||12.7kWh per day|
|5kW Solar System||21.2kWh per day|
|6.6kW Solar System||30.0kWh per day|
|10kW Solar System||42.4kWh per day|
This means that with a 5kW solar system will cover an average home’s energy use. Whether it would best to go smaller or larger than 5kW for your home will depend on:
- How much of the solar power can you self-consume during the day
- What your budget is for a solar project
- Whether you want a good return on investment, or want to cover your entire energy bill with the assistance of a solar battery

More sunshine means more up-front Federal Government Solar Rebates
The federal government offers what are effectively up-front discounts on solar PV system installation costs under the small-scale portion of Australia’s Renewable Energy Target (RET). This ‘discount’ is usually applied directly to the price of your system by your installer. The amount of the incentive depends on your location – sunnier locales receive a bigger discount. The Gold Coast is technically in the second sunniest ‘zone’ under the scheme, the same one as Brisbane. As an example see the below system sizes and estimates of the rebate they would receive as of 2020:
|Solar System Size||STC Rebate*|
|1.5kW Solar System||$803|
|3kW Solar System||$1643|
|5kW Solar System||$2774|
|10kW Solar System||$5548|
