When Australians say “solar rebate,” they usually mean the STC point-of-sale discount — your installer reduces the invoice in exchange for the Small-scale Technology Certificates your system creates. It is not a cheque from the Tax Office. Understanding that mechanism prevents double-counting discounts and clarifies how state rebates and battery subsidies stack in 2026.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.

Gross system price minus STC assignment value equals the net price you pay (before state programs). Demand the STC dollar amount, assumed $/STC and certificate count. Opaque “government rebate applied” lines hide errors.
Using MrSolar reference data (spot about $39.85 as of 5 August 2026, four deeming years), a 6.6kW Zone 3 system is roughly a $1,435 federal discount; Zone 4 about $1,235; higher zones more. Exact figures round per CER methods.
Assignment at sale is the default. Self-creation is possible but administrative. Most homeowners prefer the certainty of an upfront discount from a CEC-accredited retailer who clears certificates professionally.
Victoria's Solar Homes program can add an upfront solar discount for eligible households on top of STCs. NSW and Tasmania currently lean on federal STCs alone for panels. Never assume every state pays a second panel rebate.
Cheaper Home Batteries (~$372/kWh usable since 1 July 2025), QLD Battery Booster, SA Home Battery Scheme support and VIC battery pathways are not STCs for panels. Keep them itemised so you can audit eligibility.
If a price looks impossibly low, check whether STCs are included, whether CEC accreditation is current, and whether DNSP fees are excluded. Compare three clear net prices via MrSolar.
