If you are planning to install solar panels in Australia in 2026, understanding the full rebate landscape before you sign a contract is one of the most valuable things you can do. The federal Small-scale Technology Certificate scheme provides a significant upfront discount regardless of where you live, while state and territory governments offer additional incentives that vary considerably in their structure, eligibility, and value. This guide maps out every solar rebate available by state right now.

How the federal solar rebate works across Australia

The Small-scale Technology Certificate (STC) programme is the foundation of Australia's solar rebate system and applies in every state and territory. Your accredited installer generates STCs on your behalf based on your system's capacity and your location's solar zone, then surrenders them to the solar market in exchange for an upfront discount applied directly to your installation invoice.

In 2026, STCs are trading near $39 to $40 per certificate on the spot market. A standard 6.6kW system in Zone 3 (which covers Sydney, Brisbane, Adelaide, and Perth) generates approximately 100 to 105 STCs, translating to an upfront discount of around $3,900 to $4,200. A 10kW system generates approximately 153 STCs, worth approximately $5,900 to $6,100.

The STC scheme steps down by one year's worth of certificates each January. In 2026, systems generate certificates calculated on 14 remaining years of the programme. By 2030, this will be 10 years, and the scheme ends on 31 December 2030. Installing sooner means a larger rebate.

Solar panel rebates by state and territory in 2026

New South Wales solar rebate 2026

NSW does not currently offer a standalone state solar panel rebate. The federal STC programme is the primary support mechanism for NSW households. However, the NSW Peak Demand Reduction Scheme may provide additional rebate value for eligible systems that include battery storage. Confirm current PDRS eligibility before committing to a battery-ready installation.

Victoria solar rebate 2026

Victoria's Solar Homes Programme remains Australia's most substantial state-level solar incentive. In 2026, eligible Victorian households can receive a rebate of up to $1,400 on solar panel installation, subject to household income limits and property value caps. The programme also offers an interest-free loan of up to $1,400 for eligible households who do not qualify for or use the full rebate. Rounds open periodically, and availability can vary throughout the year. The Solar Homes Programme rebate is stacked on top of the federal STC discount.

Queensland solar rebate 2026

Queensland has no dedicated state solar panel rebate in 2026. The federal STC programme is the primary incentive for Queensland residents. However, some network distribution businesses and local councils have run targeted subsidy programmes, so checking with your installer about any current local incentives is worthwhile.

South Australia solar rebate 2026

South Australia relies on the federal STC rebate for solar panels. The state's primary battery-focused incentive, the Home Battery Scheme, has a separate application process and focuses on battery storage rather than panels. If you are installing both panels and a battery, both the STC rebate and any applicable battery incentive may apply to their respective components.

Western Australia solar rebate 2026

WA Synergy customers in the South West Interconnected System (SWIS) area can access the federal STC rebate through their accredited installer in the same way as other states. Additionally, the Distributed Energy Buyback Scheme (DEBS) provides ongoing export payments for solar generation, which is a separate financial benefit rather than an installation rebate.

Tasmania solar rebate 2026

Tasmanian households access the federal STC rebate for solar installations. Tasmania falls in a lower solar irradiance zone than mainland states, which reduces STC generation slightly compared to mainland locations. The Tasmanian government has not announced a dedicated state solar rebate as of mid-2026.

Australian Capital Territory solar rebate 2026

The ACT's Sustainable Household Scheme offers interest-free loans of up to $15,000 for eligible ACT residents installing solar panels, batteries, or other sustainable home upgrades. This loan is stacked on top of the federal STC rebate. The ACT scheme covers both solar panels and battery storage under the one loan facility, making it one of Australia's most generous state-level support packages for residential energy upgrades.

Northern Territory solar rebate 2026

The NT government offers a direct rebate of $400 per kilowatt of solar installed, up to a maximum of $2,000 for a 5kW system. This NT rebate stacks with the federal STC programme, giving NT residents a combined rebate that can significantly reduce their upfront cost. The rebate is available for eligible households and small businesses.

How to claim solar panel rebates in Australia

In all states and territories, the STC federal rebate is processed automatically by your accredited installer. You do not apply for it separately. State rebates have varying application processes: some require a pre-approval before installation, others are claimed after installation, and some are delivered as loans rather than grants. Your installer should advise on the relevant process in your state.

Frequently asked questions

Is there a solar rebate for everyone in Australia?

Yes. The federal STC rebate applies to all Australian households installing eligible solar systems through an accredited installer, with no income test. State and territory incentives have varying eligibility requirements.

Can I combine multiple solar rebates?

Yes, in most cases. The federal STC rebate can be combined with state government incentives in all states that offer them. Confirm stackability with your installer and any relevant state programme before applying.

Does the solar rebate cover battery storage?

No. The STC rebate applies only to solar panels and inverters, not to battery storage. Battery storage has a separate federal rebate through the Cheaper Home Batteries Programme. Some state battery incentives also exist independently of the solar panel rebate.

Do I need to apply for the STC rebate myself?

No. Your accredited installer applies the STC rebate on your behalf and deducts it from your installation invoice upfront. You receive the benefit immediately without any separate application.

When does the solar rebate end in Australia?

The federal STC scheme is legislated to end on 31 December 2030. Each year until then, the value of the rebate reduces by one year's worth of certificates. State programmes have their own timelines, which can change with government budgets.
