Every federal and state incentive explained in plain English. STCs, battery rebates, feed-in tariffs—know exactly what you're entitled to.
Check My EligibilityThe federal battery rebate changed significantly on 1 May 2026. Larger batteries now receive reduced support through a tiered discount system. If you're considering a battery over 14 kWh, install before May 2026 to maximize your rebate.
The Small-scale Renewable Energy Scheme (SRES) is Australia's main solar incentive, available nationwide. It reduces your upfront cost by hundreds—or thousands—of dollars [^7^].
| System Size | Typical STCs | Rebate Value (~$40/STC) |
|---|---|---|
| 6.6 kW | ~54 | ~$2,160 |
| 8 kW | ~65 | ~$2,600 |
| 10 kW | ~82 | ~$3,280 |
| 13 kW | ~106 | ~$4,240 |
The STC scheme reduces by approximately 4-5% each year and ends completely on 31 December 2030. Each year you wait, the rebate gets smaller. A 6.6 kW system that gets ~$2,160 in 2025 will only receive ~$360 in 2030 [^15^].
From 1 July 2025, home batteries are included in the federal STC scheme through the Cheaper Home Batteries Program. This is a game-changer for battery affordability [^6^][^12^].
The rebate now uses a tiered system that reduces support for larger batteries [^12^]:
Example: A 40 kWh battery installed before May 2026 gets ~$6,464 off. After May 2026, it drops to ~$2,400 off.
| Period | Rate per kWh | 10 kWh Battery Discount |
|---|---|---|
| Rest of 2025 | $372 | ~$3,720 |
| Jan–Apr 2026 | $336 | ~$3,360 |
| May–Dec 2026 | $272 | ~$2,720 |
| 2027 | $208–$228 | ~$2,080–$2,280 |
| 2030 (final year) | $84 | ~$840 |

When your solar exports excess energy to the grid, your retailer pays you a feed-in tariff. Rates vary dramatically by state and retailer [^8^][^10^].
| State | Minimum Rate | Typical Range | Notes |
|---|---|---|---|
| VIC | 0c/kWh | 0c – 11c | Deregulated from July 2025. Shop around for best rates. |
| NSW | None | 4c – 10c | No minimum. AGL, Origin, EnergyAustralia offer ~8c. |
| QLD (SEQ) | None | 3c – 10c | Brisbane/Gold Coast retailer-set. Regional (Ergon) has 8.66c minimum. |
| SA | None | 2c – 10c | No minimum. Engie offers up to 10c. |
| WA | 2c (off-peak) | 2c – 10c | Distributed Energy Buyback Scheme (DEBS). Peak exports earn more. |
| TAS | 8.782c | 8.782c | Regulated by Tasmanian Economic Regulator. Reviewed annually. |
| ACT | None | 4c – 10c | Retailer-set rates. |
| NT | 9.33c | 9.33c – 18.66c | Highest rates in Australia. Jacana Energy offers time-of-use up to 18.66c. |

With minimum rates dropping to 0c in some states (like Victoria from July 2025), exporting during off-peak may earn nothing. Consider:
Solar Homes Program offers up to $1,400 rebate + optional $1,400 interest-free loan for solar panels. Battery loans closed June 2025, but federal battery rebate applies. Hot water rebates up to $1,400 for locally made products [^9^].
Previous battery installation rebate ended June 2025. New VPP incentive offers up to $1,500 for connecting batteries to Virtual Power Plants (from July 2025). Can stack with federal battery rebate for new installations [^13^].
No state-specific solar or battery rebates currently. Regional Queensland households on Ergon network receive regulated 8.66c/kWh minimum feed-in tariff. South East Queensland rates are retailer-set [^8^].
No state rebates for solar or batteries. Home battery scheme closed. Retailers offer competitive feed-in tariffs (up to 10c). Consider VPP programs for additional battery income [^8^].
Residential Battery Scheme offers combined rebate up to $5,000 (Synergy) or $7,500 (Horizon Power) plus no-interest loans up to $10,000. Can stack with federal rebate. Must join VPP [^12^].
No state-specific rebates. Regulated feed-in tariff of 8.782c/kWh (July 2025–June 2026). Aurora Energy is main retailer. Battery storage less critical due to high hydroelectric base [^8^].
To claim any solar or battery rebate, you generally need to meet these requirements:
You cannot receive STCs for the same system twice. If you're upgrading an existing solar system, only the new components (additional panels, new inverter, battery) are eligible for certificates.
| Date | Change | Impact |
|---|---|---|
| Now – Apr 2026 | Federal battery rebate at $336/kWh | Good time to install batteries |
| 1 May 2026 | Battery rebate drops to $272/kWh + tiered system begins | Larger batteries (14+ kWh) get significantly less support |
| 1 Jan 2027 | Battery rebate drops to $228/kWh | Continuing gradual decline |
| 31 Dec 2030 | STC scheme ends completely | No more federal solar or battery rebates |
If you're considering solar, sooner is better. The STC rebate drops every year and ends in 2030. For batteries, install before May 2026 if you want a system larger than 14 kWh to avoid the tiered reduction.
