Australian Solar Feed-in Tariffs by State in 2026: NSW, VIC, QLD Compared

Australia's federal STC rebate lowers install cost everywhere — but your feed-in tariff (FiT) depends on state rules and which retailer you choose. In 2026, the spread between best and worst FiT plans can mean hundreds of dollars per year.

Key takeaway: Shop your electricity retailer for FiT the same way you shop installers. A cheap system with a poor FiT underperforms for a decade.

National vs state incentives

Layer	What it does
STCs (federal)	Upfront discount on system cost by zone/size
State rebates	VIC Solar Homes, NSW battery incentives, etc. — check eligibility
FiT (retailer)	¢/kWh paid for exports — not uniform

NSW (2026 snapshot)

• Competitive retail market — FiTs often 5–12 c/kWh depending on plan
• Battery incentive programs may apply — verify current NSW Climate and Energy Authority guidance
• Time-of-use plans reward self-consumption in evening peaks

Victoria (2026 snapshot)

• Solar Homes program history affects eligibility — new applicants should confirm current rebate/battery loan status
• Minimum retailer FiT set by regulation — compare above-minimum offers
• Winter yield lower than QLD — size for annual bill, not summer peak only

Queensland (2026 snapshot)

• Strong sun = high production; FiT offers vary widely
• Regional networks (Ergon vs Energex) affect connection rules
• Air-conditioning-heavy homes: prioritize west roof or larger array

Typical installed costs (AUD, indicative)

System	Range	Payback driver
6.6 kW	$5,500–$9,000	Self-use + FiT
10 kW	$8,500–$13,000	Large family / pool
+ battery 10 kWh	+$9,000–$14,000	Evening load, backup

Questions for Australian installers

1. What FiT did you assume — and can I switch retailers later?
2. Is the inverter export-limit compliant with my DNSP?
3. STC assignment — am I signing STCs to you (standard)?
4. Warranty: product vs installer workmanship
