How much does solar save per year in Australia?
A typical 6.6kW system saves $1,500 to $2,100 a year, depending on your electricity rates and how much of the solar you use directly. Homes with dearer power and daytime use save the most.
How long does solar take to pay for itself?
On our price and savings bands a 6.6kW system pays for itself in about 2 to 4 years after the federal STC rebate, depending on your zone and how much power you use in the day. For your own figures, use the payback calculator.
