Climate in Brisbane - does solar make sense?
The short answer is YES; solar absolutely makes sense in Brisbane! Brisbane's climate is gorgeous. Summers are hot with an average high of 29°, while our sunny winters are warm, with an average low of 21.3°. The level of solar irradiation in Brisbane is 4.81kWh/sq m/day, meaning that the sun is beaming 4.81kWh of power per square metre onto solar panels you install in Brisbane every single day!
Solar power installations in Brisbane
As of August 2019, roughly 30% of Brisbane's homes are covered in solar panels!
Average solar system size in Brisbane
Based on current installations in Brisbane, the average solar system size is 6.6kW. During the early years of solar power in Australia (when installing solar was about 5X as expensive as it is now), smaller systems were very popular and energy retailers would sell solar systems to their customers that were too small to completely reduce their electricity bills (surprise, surprise).
We receive a lot of enquiries from homeowners who would like to add panels to an existing solar system they installed a few years ago (which can be a costly exercise), so in general, we recommend installing as many panels as your budget and roof space allows. The 6.6kW solar system is a great system that will ‘future proof’ you against continually rising electricity prices and will enable you to take full advantage of the generous government solar rebate as it stands.
6.6kW solar system Brisbane
A 6.6kW solar power system is perfect for Brisbane homes. 6.6kW solar systems typically come with 20 x 330W solar panels, and a 5kW inverter - allowing you to claim 33% more solar rebate than a 5kW system, and also help you to produce more power during low light conditions. Residential solar panels are roughly 1.7m long by 1m wide - so installing a 6.6kW system on your home will require at least 34m2 of roof area.
The average daily output of a high-quality 6.6kW system installed in Brisbane is 27.7kWh of clean, renewable energy. The high daily production means you'll be generating roughly 10,110 kWh per year, saving you $2000+ per year on electricity costs!
At the time of writing (January 2020), a good quality 6.6kW solar power system installed in Brisbane will cost you between $5200 - $9500. The higher end of this price bracket is for premium panels (LG, Kyocera, Sunpower) installed with panel-level optimisation (micro-inverters or power optimisers). The best way to compare solar power systems prices is to click 'Get Quotes' at the top of the screen and our 3 highest rated solar installers will provide you with quotes specific to your home in Brisbane.
A 6.6kW solar system installed in Brisbane will pay for itself within 3-5 years, making it an attractive investment!
Solar panel tilt angle in Brisbane
The slope of your roof is usually the best angle at which to install your solar panels. If you have a flat roof, your chosen solar company will fit tilt frames, to ensure that your solar panels are at the ideal angle for maximum energy production. In Brisbane, the perfect solar panel tilt angle is 27.4°.
Ideal solar panel direction in Brisbane
The direction that your solar panels face can have a huge impact on the overall amount of energy produced by your system. In Australia, a north-facing solar system will produce the most energy - with peak production during the middle of the day when the sun is at its highest point.
However, solar systems installed on the North-East or North-West aspects of the roof will produce only slightly less power than North facing installations (see image below for the difference in energy production for different roof aspects).
As solar panel prices and feed-in tariff rates have fallen, East-West facing installations are becoming increasingly popular because they start generating power earlier in the day and finish later in the afternoon - which follows most families’ energy usage patterns more closely. This means that even though the system is producing less energy overall, more of the energy is being self-consumed making East-West installations an attractive prospect.
When deciding which aspect of your roof best suits your energy requirements, you need to take into consideration how you use power in your home. If you have kids at school and are away from the house for the majority of the day then it could be beneficial to install an east-west solar array.
Maximising value from your solar system in Brisbane
We recommend cleaning your solar system at least once per year and always self-consuming as much of your solar energy as possible to maximise the return from your solar investment in Brisbane! For households where trees might cause shading on the roof, we recommend the use of power optimisers or mirco-inverters to maximise the output of your system and make sure only the shaded panel is losing efficiency (not the entire string of panels) as explained in our solar tips guide.

Latest info on solar rebates in QLD
Homeowners installing solar panels in sunny Queensland are entitled to the Federal Government's STC 'rebate'. This financial incentive comes in the form of Small-Scale Technology Certificates, commonly referred to as STCs. When you install a solar power system, a certain number of STCs are created based on the size and the location of your solar installation. Each STC carries a monetary value, and the total value of these certificates equates to your 'solar rebate.'
Your chosen solar company will handle the application for the rebate on your behalf and apply the value of this rebate as a discount at the point of sale. You can read more in-depth about the STC rebate in our recent blog post on the subject. To make life easy, we have calculated the value of the STC rebate you are entitled to for common solar system sizes here in Queensland below:
|System Size||Federal Government Rebate (STC's)||State Government Rebate|
|2 kW||$1080||Solar for renters (trial)|
|3 kW||$1620||Solar for renters (trial)|
|4 kW||$2160||Solar for renters (trial)|
|5 kW||$2736||Solar for renters (trial)|
|6.6 kW||$3600||Solar for renters (trial)|
|10 kW||$5472||Solar for renters (trial)|
*Please note that the STC rebate calculations are based on solar panels installed in Brisbane, QLD (Zone 3) using an STC price of $36.00.
In addition to the Federal Government STC rebate, you may be eligible for the following Queensland State Government rebate:
Solar for Renters (trial) - rebates of up to $3500 are available to landlords that install a solar system on their rental property. During the trial phase, the rental property must be in the Bundaberg, Gladstone, or Townsville local government areas. There are 1000 rebates available during the trial of this scheme.
Feed-in tariff rates offered by retailers in QLD
Solar feed-in tariffs (FITs) are the amount you get paid by your energy retailer for the excess energy your solar system exports back into the grid. During the day, it’s typical for your solar power system to generate more power than is being used in your home. This excess means that if you have a grid-connected solar system, the energy you don't use feeds back into the grid, and your energy retailer will pay you a fixed amount per kWh of energy that you send to them. The retailer-provided solar FITs listed here do not include any bonus feed-in tariff that may be provided by the QLD State Government.
|Energy Retailer||Min rate (per kWh)||Max rate (per kWh)|
|DC Power Co||15.0c||15.0c|
|Locality Planning Energy||10.0c||10.0c|
|Future X Power||7.0c||7.0c|
*The feed-in tariff rates you are entitled to vary depending on the energy plan you choose with the retailer. Feed-in tariff rates displayed are correct as of October 2019.
Simple guide to sizing your solar system in QLD
Choosing the right system size depends on many factors, including how much power you use during daylight hours, your roof orientation, whether shading will be an issue, and how much roof space you have at your home or business. In general, if you can afford to pay your power bills, then you can afford to invest in solar because the system will pay for itself in energy savings. As a rough guide, you can compare the average daily power usage on your power bill to the average daily output of common system sizes we have calculated in the table below:
|System Size||Avg daily output||Return on Investment|
|2 kW||8.4 kWh||3 - 5 years|
|3 kW||12.6 kWh||3 - 5 years|
|4 kW||16.8 kWh||3 - 5 years|
|5 kW||21.0 kWh||3 - 5 years|
|6.6 kW||27.7 kWh||3 - 5 years|
|10 kW||42.0 kWh||3 - 5 years|
*Please note that the location used for above the daily output calculations is Brisbane, QLD - based on the Clean Energy Council GC Design Guidelines.
