It gives an indicative estimate based on Australia regional solar output and average power prices — good for a ballpark. Your exact saving depends on your roof, shading, usage pattern and power plan, which a vetted local installer confirms at a free on-site assessment.
Most Australian homes save around $1,000–$2,500 a year, and payback is fast (typically 3–6 years) thanks to the rebate and high power prices. Use the calculator above for a state estimate.
Australian system prices are quoted after the federal STC rebate, so the payback shown already reflects the rebate-reduced cost. Battery rebates apply on top if you add storage.
As a rough guide, match the system to your power bill: smaller bills suit a 3–5 kW system, average homes a 6.6 kW system, and larger homes or those with EVs a 9–10 kW system. The calculator suggests a size from your bill; your installer confirms it.
For most Australian homes, yes — payback is typically 3–6 years, one of the fastest in the world. See our full is-solar-worth-it guide.
