The average power output for a 15 kW solar power system in Brisbane is 60 to 80 kWh thanks to Queensland's sunny weather. But this number may vary depending on many factors such as location, climate, orientations and tilt angle of the panel, operating temperature of the panels.
With these panels, obviously one can generate a serious amount of solar energy. For most houses, this could be too much. It is appropriate for families using over 40 kWh energy per day. It is more common for a business than a home.
