These are approximate figures based on a standardized household consumption of 5,000 kWh/year and an estimated electricity rate of A$0.386/kWh in Australia. Local incentives may reduce the upfront cost — check current subsidy, tax-credit, or VAT programs in Australia, as these can meaningfully shorten the payback period.
Figures are estimates based on typical system assumptions and the latest available electricity-price and billing data for Australia. Actual costs, tariffs, net-metering rules, and incentives vary by utility and change over time — confirm with a local installer or energy authority before making decisions.
How solar billing works in Australia
Exports and imports are priced separately, usually at different rates.
In Australia, rooftop solar appears to fall under a net-billing-style approach, where the energy you export and the energy you import are typically valued separately rather than simply cancelling out. Exports are often credited at a rate that may be lower than the retail price you pay for imported power, which generally rewards using your own generation as it is produced. The precise export and import prices vary by region and utility and change over time, so they should be confirmed locally.
Solar incentives in Australia
Small-scale Renewable Energy Scheme (SRES) — STCs
rebateEstimateEligible small-scale solar systems can create Small-scale Technology Certificates (STCs), which are typically assigned to the installer and discounted off the upfront purchase price. The number of certificates and their value vary and the scheme is scheduled to phase down over time.
State feed-in tariffs
