How Much Electricity does a Solar System produce in Australia?
The answer depends on a few factors, and these can include.
The Size of the system.
The Location.
The Roof Direction.
Any trees causing shade.
I can give an example of a 3.24kWh system in SE Queensland, with Panels facing North, and no shade.

This was installed in September 2018, so the chart starts at September.

September and November seem to be the best months for solar generation, while June and July are the worst.
May, June and July produced 21.6% of the solar produced in these three years, at an average of 13.0 kWh per day.
September, October and November produced 27.8% of the solar produced in these three years, at an average of 16.7 kWh per day.
But take note of the fact that some months can vary a lot, while others are quite standard.
December, for example, varied between 16.81 and 13.55, a 24.1% difference between the years, while November varied between 17.43 and 17.2, only a 1.3% difference.
The term kWh stands for KiloWatt-Hour, a unit of energy that measures how much electricity you use, or supply, and is used by Electricity providers to calculate their charge for your Electricity consumption.
