Solar Generation & Return on investment
A solar panel system in Adelaide, which is installed with good access to the sun, can get up to a massive 4.42 kWh of solar energy per kW installed on average per day throughout the year.
See our Adelaide solar case study for one Adelaide family’s thoughts on their solar investment.
Average daily solar output estimate*
This data assumes an optimal 35° pitch for Adelaide, see next section for details on optimal panel angles.
Adelaide receives a lot of sun throughout the year, however the winter months and the shoulder seasons do see a considerable drop in sunshine, with May to June receiving only a little over 3 kWh.
The best months for solar production in Adelaide are November, December, January and February, all of which should produce over 5 kWh on average with an optimally installed system.
Per kW installed
Full year average: 4.42 kWh
Summer (Jan): 5.41 kWh
Winter (Jul): 3.40 kWh
For a 5kW system
Full year average: 22.1 kWh
Summer (Jan): 27.05 kWh
Winter (Jul): 17.0 kWh
Estimated Daily Solar Production | Per kW installed
Optimal panel angle
The optimal panel angle in Adelaide for year round solar production is 35° 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.
Here is a guide to the different production you will get throughout the year with different panel angles:
Winter optimised production | 50° pitch*
Per kW installed
Full year average: 4.23 kWh
Summer (Jan): 4.72 kWh
Winter (Jul): 3.63 kWh
Summer optimised production | 20° pitch*
Per kW installed
Full year average: 4.39 kWh
Summer (Jan): 5.85 kWh
Winter (Jul): 2.98 kWh
* This data is purely theoretical, based on solar irradiance and a 12% derating, every installation is different and should expect different outputs.

Cost of Solar in Adelaide
Adelaide 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.
