The Australian solar rebate 2026 landscape continues to evolve. The federal scheme is still in place but has stepped down again; several state battery programs have closed, and Victoria is tightening eligibility mid-year. For homeowners considering solar, understanding exactly what’s on offer right now — and what’s changed — is essential before making any decisions. This guide covers the current state of solar rebates, how uptake is tracking, where government support is now focused, and what to expect in the months ahead.
Australian Solar Rebates in 2026: State by State
The Federal STC Scheme
The cornerstone of the Australian solar rebate 2026 system remains the federal Small-scale Renewable Energy Scheme (SRES). It delivers an upfront discount through Small-scale Technology Certificates (STCs), valued at approximately $38–$40 each. Your installer applies the discount directly to your quote — no separate application is needed.
From 1 January 2026, the deeming period dropped from 6 years to 5 years. This reduced the STC count for a typical 6.6kW system by around 9 certificates. A standard 6.6kW system in Zone 3 (Victoria, ACT) now generates approximately 46 STCs, equating to a rebate of around $1,840 — roughly $340–$500 less than in 2025. The scheme steps down each year and closes entirely at the end of 2030.
Victoria
Victoria’s Solar Homes Program continues in 2026, offering up to $1,400 for eligible households installing solar panels, plus a matching interest-free loan. The rebate amount is unchanged. However, a significant eligibility change is taking effect: from 1 July 2026, the combined household income cap drops from $210,000 to $150,000 per year. Households earning between $150,000 and $210,000 must submit a complete application by 5pm on 30 June 2026 to secure access under the current rules. For households earning under $150,000, nothing changes.
Victoria’s standalone state battery rebate closed in late 2024. Victorian residents can still access the federal Cheaper Home Batteries Program, but no additional state battery rebate exists in 2026.
New South Wales
NSW does not currently offer a standalone state solar panel rebate. The federal STC scheme is the primary incentive for solar-only installations. For batteries, the Peak Demand Reduction Scheme (PDRS) provides an upfront incentive for households that connect their battery to an approved Virtual Power Plant (VPP). The amount varies depending on battery size and the VPP contract agreed to — larger batteries up to 28kWh attract a higher incentive. Homeowners can stack this with the federal Cheaper Home Batteries Program, making NSW one of the better states for combined battery savings. The Empowering Homes Program — which previously offered interest-free loans for solar-battery systems — has closed.
Western Australia
WA’s Residential Battery Scheme continues to deliver meaningful support in 2026. Synergy customers can claim up to $1,300 ($130 per usable kWh, capped at 10kWh). Horizon Power customers in regional WA can claim up to $3,800 ($380 per kWh). VPP participation is mandatory. Homeowners can stack this with the federal Cheaper Home Batteries Program, unlocking combined savings of up to $4,000–$6,500 depending on retailer and battery size.
Australian Capital Territory
The ACT’s Sustainable Household Scheme offers low-interest loans of up to $15,000 for energy-efficient upgrades. Eligible products include household batteries, heat pumps, EV charging infrastructure, electric vehicles, and ceiling insulation. Solar panels no longer qualify for standard applicants following changes in July 2025. Concession card holders can still access zero-interest loans and solar loans through the separate Home Energy Support Program. From 1 July 2026, the loan cap rises to $20,000, the EV price threshold moves to $60,000, and electric cargo bikes join the eligible products list from September 2026.
South Australia and Queensland
South Australia relies on the federal STC scheme for solar support, with no standalone state rebate. Queensland’s Battery Booster program closed in 2024. In both states, the federal Cheaper Home Batteries Program is now the main battery rebate available. Feed-in tariffs in SA and QLD currently range from 5–12 cents per kWh depending on retailer and plan.
How the Australian Solar Rebate 2026 Compares to 2025
The most significant changes between 2025 and 2026 are:
- Federal STC rebate reduced from 1 January 2026 — the deeming period step-down cut the value of a typical 6.6kW system rebate by approximately $340–$500
- Federal battery rebate restructured from 1 May 2026 — the STC factor dropped from 8.4 to 6.8, and a tapering structure now applies to batteries above 14kWh
- Victoria Solar Homes income cap drops from $210,000 to $150,000 from 1 July 2026
- Victoria’s state battery rebate remains closed following its 2024 closure
- Queensland’s Battery Booster remains closed following its 2024 closure
- NSW Empowering Homes Program has closed — the PDRS VPP incentive is now the primary state battery support, with the amount varying by battery size and VPP contract
- ACT Sustainable Household Scheme moved to a 3% interest rate from July 2025, dropped solar panel eligibility for standard applicants, and lifts its loan cap to $20,000 from 1 July 2026
The federal STC scheme will step down again from 1 January 2027, and the battery rebate will also reduce further at that point. Installing sooner delivers better rebate outcomes than waiting.
Australian Solar Rebate 2026: Uptake in 2025 and Outlook
Australia’s rooftop solar market reached a notable milestone in 2025. Rooftop solar now accounts for 28.3 GW of installed capacity across more than 4.2 million homes and small businesses, according to the Clean Energy Council. In the second half of 2025, rooftop solar contributed 14.2% of Australia’s total electricity generation — nearly double its 2020 contribution.
However, 2025 brought the first dip in installation volumes after ten consecutive years of growth. The Clean Energy Regulator’s December Quarter 2025 report recorded 269,000 systems installed in 2025, down from 319,000 in 2024. That’s a 16% drop in installation numbers and a capacity reduction from 3.2 GW to 2.8 GW. The CER links this primarily to installers shifting capacity toward battery retrofit work after the Cheaper Home Batteries Program launched — not a structural decline in demand.
The 2026 outlook is more positive. Understanding the Australian solar rebate 2026 picture helps explain why: the Clean Energy Regulator projects rooftop solar to rebound to 3.0–3.7 GW this year. Battery uptake looks particularly strong, with the CER forecasting 350,000–520,000 residential battery installations in 2026 — representing 8–12 GWh of new storage capacity.
Is the Market Near Saturation?
With more than 4.2 million rooftop solar systems now installed, saturation is a fair question for the Australian solar rebate 2026 market. Nevertheless, meaningful demand continues across several segments.
Older systems installed before 2015 are increasingly reaching the end of their effective inverter lifespan, driving a growing replacement and upgrade market. Apartments and rental properties remain significantly underserved, though programs like NSW’s Solar and Energy Efficiency Grant for Apartments are starting to address this. Households adding batteries to existing solar — rather than installing new panels — also represent a growing share of 2026 activity.
South Australia leads the country in household solar penetration. Tasmania and the Northern Territory remain below the national average, leaving room for continued growth in those regions.
Where Is Government Support Focused?
Government policy in 2026 has clearly shifted toward battery storage and grid stability, rather than expanding solar panel uptake alone.
The reason is straightforward: rooftop solar is now so widespread that daytime electricity prices and feed-in tariffs have fallen sharply. Feed-in tariffs in most states now sit at just 5–8 cents per kWh. Storing solar energy and using it at night or during peak tariff periods delivers far more value than exporting it to the grid.
The federal Cheaper Home Batteries Program, the NSW PDRS VPP incentive, and the WA Residential Battery Scheme all reflect this direction. VPP participation requirements in NSW and WA also mean batteries are increasingly functioning as grid assets — not just household tools. That said, the federal STC scheme remains the single largest financial incentive for Australian homeowners going solar in 2026.
What the Australian Solar Rebate 2026 Means for Homeowners
For most Australian households, the Australian solar rebate 2026 still makes solar a strong financial investment. Electricity prices rose by up to 9.7% for residential customers in 2025-26 under the Australian Energy Regulator’s Default Market Offer. Further increases loom as coal plants retire and infrastructure costs rise. The bill savings from solar keep growing stronger as a result.
The key points for homeowners to take away are:
- The federal STC rebate is still available but smaller than last year — and it reduces again on 1 January 2027
- Victorian households earning between $150,000 and $210,000 need to act before 30 June 2026 to access current rebate settings
- Battery rebates are strongest in NSW and WA when homeowners stack state and federal programs
- Installing solar and battery together in 2026 delivers better combined rebate outcomes than adding a battery later
Always use a Solar Accreditation Australia (SAA)-accredited installer and confirm eligibility for available rebates before signing a contract.
Final Thoughts
The Australian solar rebate 2026 landscape is more complex than it was a year ago — but the opportunity for homeowners remains strong. The federal STC scheme keeps reducing costs for solar installations. The Cheaper Home Batteries Program exceeded all expectations in its first year. State programs in Victoria, NSW, and WA continue to add support on top. What’s changed is that the detail matters more than ever. Several programs have closed, eligibility rules have tightened, and rebate values follow a known step-down schedule. Homeowners who understand what’s available now — and act before further reductions take effect — are best placed to maximise their savings and lock in long-term energy independence.
