Common Questions
How much does solar save per year in Australia?
The average Australian household saves $1,200 to $2,800 per year with solar, depending on system size, electricity rates, and how much solar energy you use directly. Homes in South Australia and NSW typically save the most due to higher electricity prices.
What is the payback period for solar in 2026?
Most solar systems pay for themselves in 3 to 5 years in Australia after the federal STC rebate. South Australia averages under 3 years, while Victoria and Tasmania average 4 to 6 years. After payback, your solar system generates free electricity for another 20+ years.
