Commercial solar rebates Australia businesses can access can significantly change the financial case for investing in onsite renewable energy. Solar already gives organisations an opportunity to reduce grid electricity consumption, manage long-term energy costs and work towards emissions targets. However, government-backed incentives can further reduce the cost of making that transition.
Importantly, there is no single nationwide commercial solar rebate that applies equally to every Australian business. Instead, businesses may benefit from certificate-based federal incentives, battery support, state schemes and targeted grants.
The available benefit depends on factors such as system capacity, installation date, location and technology. Therefore, businesses should understand the current incentive landscape before making an investment decision.
Commercial solar incentives generally reduce either the initial capital cost of installing renewable technology or improve its financial return over time.
Australia's Renewable Energy Target includes two important certificate mechanisms: the Small-scale Renewable Energy Scheme and Large-scale Renewable Energy Target. Eligible renewable systems can participate in the appropriate scheme and create certificates with a financial value.
Consequently, businesses should not think of every incentive as a cash payment from the government. In many cases, the financial benefit comes from certificates that have a market value and can effectively reduce the project's cost.
| Incentive | Typical Application | Main Benefit |
| Small-scale Technology Certificates | Eligible smaller solar PV systems | Reduces effective upfront installation cost |
| Large-scale Generation Certificates | Accredited large renewable power stations | Ongoing certificates based on eligible generation |
| Solar battery STCs | Eligible battery systems | Reduces battery installation cost |
| State-based incentives | Varies by state and program | Additional discounts, certificates or grants |
| Business decarbonisation grants | Selected eligible businesses and projects | Supports planning or specific clean-energy activities |
Small-scale Technology Certificates, commonly known as STCs, are one of the most important federal incentives for smaller commercial solar projects.
Under the current Small-scale Renewable Energy Scheme rules, eligible solar PV systems can receive STCs. The Clean Energy Regulator states that solar PV eligibility under the existing small-scale arrangements is limited to systems with a rating of no more than 100 kW and annual electricity output of no more than 250 MWh.
STCs have a financial value and are commonly assigned in return for an upfront discount on an installation. Therefore, the business may not need to manage the certificate trading process itself.
The number of certificates depends on factors including geographical location, installation date and the amount of renewable electricity expected to be generated or displaced.
The solar PV deeming period also continues to decline as the scheme approaches 2030. For installations in 2026, the applicable deeming period is five years, falling to four years in 2027.
As a result, installation timing can affect the number of STCs available.
A significant development announced in August 2026 could make the STC mechanism relevant to considerably larger commercial projects.
The Australian Government announced plans to expand SRES solar PV eligibility to systems with total onsite capacity between 100 kW and 1 MW. The government intends the new arrangements to apply to eligible mid-scale solar installed from 1 October 2026, subject to the necessary regulations being in place.
This proposed change is particularly relevant to commercial, industrial and agricultural facilities that require substantially more solar capacity than smaller businesses.
However, businesses planning projects around the new threshold should verify that the regulations have commenced and confirm all technical and compliance requirements before relying on an expected STC benefit.
Large-scale Generation Certificates, or LGCs, operate differently from STCs.
Under the Large-scale Renewable Energy Target, accredited large-scale renewable power stations can create LGCs based on the renewable electricity they actually generate. One LGC represents one megawatt-hour of eligible renewable electricity generated or displaced.
Unlike the upfront nature of many STC arrangements, LGCs are created as eligible electricity is generated. They can then be traded or sold.
For commercial organisations considering larger solar projects, the distinction between STCs and LGCs is important because it affects project administration, accreditation and the timing of financial benefits.
Furthermore, the announced SRES expansion for 100 kW to 1 MW projects could change which mechanism is most appropriate for some new commercial installations from October 2026. Existing accredited large-scale systems will remain under current LRET arrangements.
Solar batteries can increase onsite use of renewable electricity by storing surplus generation for later consumption. They can also help some businesses manage peak demand and reduce exposure to expensive grid periods.
The federal Small-scale Renewable Energy Scheme now provides STCs for eligible solar batteries. Following changes from 1 May 2026, the certificate factors are designed to maintain an upfront discount of around 30 per cent while progressively declining as battery costs fall.
The incentive tapers according to usable battery capacity. Therefore, businesses considering larger commercial batteries should model the available certificate benefit carefully rather than assuming the same percentage support applies to every kilowatt-hour of capacity.
NSW businesses have an additional opportunity.
From 1 September 2026, eligible commercial and industrial businesses can access an upfront battery discount through accredited suppliers under the state's Peak Demand Reduction Scheme. The NSW Government says the program can reduce battery costs by approximately 20 to 40 per cent, depending on circumstances.
Eligible business battery installations can range from 20 kWh to 30,000 kWh. Moreover, businesses without existing solar may still qualify, although the NSW Government notes that a larger discount may apply when solar and a battery are installed within 90 days of each other.
This makes combined solar and storage analysis increasingly important for NSW businesses.
State programs change regularly and may target technologies beyond solar panels themselves.
For example, NSW operates the Energy Savings Scheme, which provides financial incentives to households and businesses for eligible energy-efficient equipment and activities. The state also operates the Peak Demand Reduction Scheme, which supports technologies including business batteries.
NSW businesses undertaking broader decarbonisation planning may also be eligible for the current Net Zero Planning Grant. As at September 2026, eligible businesses can receive up to $25,000 covering up to 50 per cent of eligible project costs, with applications scheduled to close on 30 November 2026 or earlier if funding is exhausted.
However, these programs should not automatically be treated as direct solar panel rebates. Eligibility, technologies and funding conditions differ between schemes.
Therefore, businesses should confirm current state and territory programs immediately before approving a project.
There is no universal rebate amount because commercial solar projects vary considerably.
The financial outcome can depend on:
For example, a daytime-intensive operation may consume a high proportion of its solar generation directly. Consequently, its electricity bill savings could become more important to the investment case than the rebate itself.
A business that exports substantial amounts of electricity may have a different financial outcome.
Therefore, the best assessment combines incentives with expected generation, consumption, tariffs, demand charges, maintenance costs and financing.
Not every business wants to purchase a solar system outright. A solar Power Purchase Agreement can provide another route to renewable electricity.
Under a solar PPA, a third-party provider typically installs, owns and operates the solar system. The business then purchases the electricity generated under agreed contract terms. This structure can reduce or remove the need for the business to fund the full installation upfront.
However, rebate and certificate ownership must be understood before signing. The party funding and owning the system may receive certain certificate benefits rather than the electricity customer.
Businesses should therefore compare outright ownership, financed solar and PPA arrangements on a whole-of-life basis.
The largest advertised rebate does not necessarily produce the best investment.
Before proceeding, businesses should assess their interval electricity data, roof or land availability, expected future electricity demand and operating hours. They should also model the appropriate system size rather than automatically installing the maximum capacity available.
Additionally, organisations should establish who receives STCs or LGCs, determine whether state incentives can be combined with federal support and understand how battery storage affects the economics.
Finally, businesses should compare the solar investment with their existing electricity procurement strategy. Solar, batteries, retail electricity contracts and renewable PPAs can interact, so assessing them together can produce a more effective long-term energy strategy.
Commercial solar rebates Australia businesses can access in 2026 can reduce the cost of transitioning to renewable energy, but the available support depends heavily on project size, technology, location and installation timing.
STCs remain particularly important for eligible smaller systems, while LGCs support accredited large-scale renewable generation. Meanwhile, the announced expansion of the SRES to eligible 100 kW to 1 MW solar installations could create a significant new opportunity for mid-scale commercial projects from 1 October 2026, subject to regulations commencing. Battery and state-based incentives can add further value.
However, incentives should form only one part of the investment decision. System sizing, electricity consumption, procurement arrangements and long-term savings are equally important.

Commercial solar rebates Australia businesses can access primarily include federal certificate-based incentives such as STCs for eligible small-scale systems and LGCs for accredited large-scale renewable generation. Depending on location and technology, businesses may also have access to state-based energy, battery or decarbonisation programs. Because programs and eligibility requirements change, businesses should verify current conditions before committing to an installation.
Yes. Businesses can receive STCs for eligible commercial solar systems that satisfy Small-scale Renewable Energy Scheme requirements. Under current arrangements, eligible solar PV systems are limited to no more than 100 kW, although the Australian Government intends to expand eligibility to qualifying systems between 100 kW and 1 MW from 1 October 2026, subject to regulations being in place.
Traditionally, systems above 100 kW have generally fallen outside the SRES solar PV threshold and may instead participate in the Large-scale Renewable Energy Target when properly accredited. However, the government announced in August 2026 that eligible 100 kW to 1 MW systems are intended to gain STC access from 1 October 2026. Businesses considering projects in this range should confirm commencement and eligibility before relying on the proposed incentive.
Yes, eligible batteries can receive federal STCs under the Small-scale Renewable Energy Scheme. Furthermore, NSW introduced additional upfront battery discounts for eligible businesses from September 2026. Battery economics depend on usable capacity, load profile, solar generation and peak electricity demand, so businesses should calculate total savings rather than considering the rebate alone.
Commercial solar can provide substantial long-term value when a business has suitable premises and a strong daytime electricity load. Rebates and certificates can improve the financial case, while onsite generation may reduce grid purchases and exposure to electricity costs. Nevertheless, every site differs, so businesses should model system output, self-consumption, electricity tariffs, financing, maintenance and available incentives before making an investment decision.
