Australia solar guide
Solar panel cost calculator Australia
Estimate Australian solar panel system cost, output, bill savings, feed-in tariff value, payback period and number of panels needed.
Use the main calculator with Australian inputs: AUD, your electricity import rate, your feed-in tariff, local peak sun hours and your installed cost after any rebates or incentives you want included.
Open the solar panel cost calculatorAustralia assumptions to check
- Electricity price: enter your household import rate per kWh.
- Feed-in tariff: use your retailer or network export rate for excess solar.
- Installed cost: include the final price after rebates if you want payback based on your real out-of-pocket cost.
- Solar output: Australian generation varies by state, climate, roof orientation and shading.
- Self-consumption: homes using more electricity during daylight hours may get more value from solar.
Why Australian solar payback varies
Australian solar returns depend strongly on the gap between the electricity import price and the feed-in tariff. Self-used solar normally saves more than exported solar earns, so usage timing, hot water, pool pumps, EV charging and batteries can materially change the result. Use the solar output calculator, solar savings calculator, solar payback calculator and methodology page to test the inputs.
