Below are the indicative figures for kilowatt-hours of energy a north-facing 10kW solar system will generate per day (on an average throughout the year) in Australian capital cities.

The average payback period of a good quality 10kW Solar Panel system in Sydney is 3 to 5 years. However, the results depend upon your location and energy consumption habits. If you consume more than 30kWh of electricity each day, you can expect your 10 kilowatt system to pay you back within five years.

Example Calculation

Daily Energy Production: 40 kWh
Daily Energy Consumption: 20 kWh
Electricity Rate: $0.25 per kWh
Feed-in Tariff: $0.10 per kWh

Savings from Consumption
20 kWh * $0.25 = $5 per day

Earnings from Export:
20 kWh * $0.10 = $2 per day

Total Daily Savings:
$5 (consumption savings) + $2 (feed-in earnings) = $7 per day

Annual Savings:
$7 per day * 365 days = $2,555 per year

To make optimum use of the power generated by a 10kW solar panel system, you can also add a battery to your system. The battery will save the excess, unused power in the daytime to be used at night. If you choose to get a battery, the average cost of the package will fall between $15,000 to $26,000.
