Frequently asked questions
How much does a 6.6 kW solar system cost?
A$5,000 to A$9,500 installed in August 2026 after the STC rebate: budget tier-1 panels with a value inverter at the low end, back-contact flagships with a premium European inverter at the top.
What rebates apply to solar panels in 2026?
The federal STC scheme discounts roughly A$1,800-2,500 off a 6.6 kW system at the point of sale. Some states add loans or extra incentives; see our state rebate pages.
Why do quotes for the same system vary so much?
Installer quality, racking and roof complexity, inverter brand, and sales-channel margin. A door-knocked quote routinely costs A$2,000+ more than the same hardware from a direct local installer.
