When figuring out how much power your solar system should be producing, there are two main things you'll need to determine - the size of your system and the amount of average sunlight hours where you live.
On average Tasmania gets under 5 sunlight hours a day.
Based on that here is a table of what your solar system should be generating per day on average (note that this is your total generated solar, not what you export back to the grid. Find out more about what that means here)
|System size||Expected solar production per day|
|10 kW Solar System||28.7 - 33 kWh|
|7 kW Solar System||22 - 23 kWh|
|5 kW Solar System||14.4 - 16.5 kWh|
|4 kW Solar System||11.5 - 13.2 kWh|
|3 kW Solar System||8.6 - 10 kWh|
|2 kW Solar System||5.7 - 6.6 kWh|
