Solar Generation SE Queensland
A solar panel system in Brisbane, which is installed with good access to the sun, can get up to 4.45 kWh of solar energy per kW installed on average per day throughout the year.
Average daily solar output estimate*
This data assumes an optimal 28° pitch for Brisbane, see next section for details on optimal panel angles.
As you would expect from the capital of our sunshine state, Brisbane receives very even sun throughout the year. Whilst the sunshine does drop a little over the winter and the end of autumn months, the rest of the year is quite consistent.
From September right through to February/March you can expect about 4.5-5 kWh of solar energy per day on average with an optimally installed system.
Per kW installed
Full year average: 4.45 kWh
Summer (Jan): 4.97 kWh
Winter (Jul): 3.78 kWh
For a 5kW system
Full year average: 22.25 kWh
Summer (Jan): 24.85 kWh
Winter (Jul): 18.9 kWh
Estimated Daily Solar Production | Per kW installed
Optimal panel angle
The optimal panel angle in Brisbane for year round solar production is 28° from the horizontal, and facing due North (0° azimuth). This allows for the most total production throughout the year. However, depending on when you use the most electricity, you may want to consider optimising your installation for different times in the year.
Bear in mind that roofs typically have a pitch of between 15 - 30°, and it usually makes sense if you are installing on a house, to simply lie the panels flat on the roof without changing the angle. This is due to cost, fixing and aesthetics. Installs look nicer when they are flat against the roof, they are more secure, and there is extra costs involved in changing the angle, both in parts and labour.
If you are looking for consistent solar production throughout the year, a system optimised for winter in Brisbane will nearly as much in winter as it does in summer.
Here is a guide to the different production you will get throughout the year with different panel angles:
Winter optimised production | 43° pitch*
Per kW installed
Full year average: 4.29 kWh
Summer (Jan): 4.38 kWh
Winter (Jul): 4.02 kWh
Summer optimised production | 13° pitch*
Per kW installed
Full year average: 4.39 kWh
Summer (Jan): 5.33 kWh
Winter (Jul): 3.33 kWh
* This data is purely theoretical, based on solar irradiance and a 12% derating, every installation is different and should expect different outputs.
Example solar generation
Below is a chart of actual energy generation from an example system in Brisbane. This should help illustrate how a real world system performs in both summer and winter. The graph shows the energy output in 15 min intervals.
2.4 kW system facing north, with a 25° panel angle
Winter solar production - July
Sunny day: 10.8 kWh (4.5 kWh per kW installed). Random day: 6.84 kWh (2.85 kWh per kW installed)
Summer solar production - January
Sunny day: 13.8 kWh (5.7 kWh per kW installed). Random day: 11.33 kWh (4.72 kWh per kW installed)
Cost of Solar in SE Queensland
Brisbane is in zone 3 for the federal STC rebate scheme. This means that for a 5kW system, in 2019 you are eligible for 96 certificates, which at the current price of around $30, you will receive a very handy $2880 off the upfront cost of your system. See our Solar Price Calculator for up to date calculations of STCs on your specific system size, and for a quote on the total cost of a system.
