Estimate Your Solar Savings
Enter your address and a few details about your electricity usage to estimate system size, solar generation, installation cost and long-term savings.
Select your address from the dropdown to check rooftop solar data.
Recommended solar system size
Add an address to check available rooftop solar data.
This is an indicative estimate only. Actual solar savings vary based on your roof, location, usage patterns, electricity plan, installer pricing and available incentives. Solar rebate estimates are based on Small-scale Technology Certificates and are usually applied as an upfront discount by the installer.
What your solar estimate includes
Your result combines your address, electricity bill, household size and available rooftop solar data to create a practical solar estimate.
Recommended system size
A suggested solar system size based on your electricity use, household details and available rooftop potential.
Annual generation
An estimate of how much electricity your solar system may generate across a typical year.
Install cost
A broad installed cost range to help you understand what a system of this size may cost.
Estimated rebate
An indicative rebate estimate based on common Australian solar incentive assumptions.
Yearly savings
A savings estimate based on solar self-consumption, exported energy and electricity rate assumptions.
Payback period
An estimate of how long it may take for your solar savings to offset the upfront system cost.
How your solar savings are calculated
Your estimated savings are based on how much solar electricity your system may generate, how much your household uses directly, and how much excess solar is exported back to the grid.
Solar power used directly in your home usually saves more than exported solar.
Excess solar sent to the grid may earn a smaller credit on your bill.
A battery may increase how much of your solar energy you can use at home.
