  • Please have a look at your average annual consumption number in kWh which you wrote down from the previous page. Increase the system size in the calculator above to see how big your system would need to be to create an annual amount of kWh solar energy similar to or bigger to the amount of kWh you consume. Write down how big your solar system would need to be in kW.

Disclaimer: These output calculations use sunlight data supplied by the Australian Bureau of Meteorology from most Australian weather stations from 1990 to now – as an average. The output calculations are estimates only. The calculations allow for a 14% loss of the sunlight for inverter and cable loss, slight dust on the panels and for the fact that panels will not always be pointing True North. If panels point straight West or East, are tilted to low or to high, a further reduction in output of up to 15% can occur. For site specific rather than general solar system outputs please request a site inspection and discuss the matter with your LG solar dealer.
