Commercial Solar Rebates, Grants & Incentives

Commercial Solar Rebates, Grants & Incentives

Solar for businesses in Australia has never been easier, with access to various commercial solar rebates, business solar grants and commercial solar incentives to install solar and energy efficient components. These benefits vary from state to state and are dependent on the size and type of systems installed and your business’s eligibility. This page covers the most common types of benefits available. We recommend speaking with the relevant governing bodies in your state for more information as needed. You can also get free solar quotes here at Energy Matters.

Federal commercial incentives

The following commercial solar incentives are available to all Australian businesses, irrespective of which state they are located in. Conditions may apply.

Commercial solar systems and Small-Scale Technology Certificates (STCs)

It is a common misconception that STCs are only available to residential customers. All eligible renewable energy systems under 100kW can access this federal incentive.

What are STCs and how can I access them for my commercial system?

Your system, whether a Solar PV System, Wind Turbine or Hydro System, will be assigned a designated number of STCs. These STCs are equivalent to 1MWh (megawatt hour) of energy displaced or generated by the renewable energy system. The amount of STCs assigned to your system will be dependent on the expected MWh of energy displaced or generated over the course of 5 years or a single maximum deeming period.


If you were to install a system with an expected generation capacity of 100MWh over 5 years, you would be assigned 100 STCs for your system.

Each STC has a value that is determined by the market. The current value of 1 x STC (as of December 2022) is $37. If your system has 100 x STCs, you could expect that your total STC value is $3,700.

The combined value of these STCs is usually deducted from the purchase cost of your system. Your installer will provide a point-of-sale discount and sell the STCs themselves. You can sell the STCs, via the STC Clearing House, but you will take on the risk of the fluctuating STC market.


If you purchase a $10,000 solar PV system, with a total of 100 STCs assigned to the system, you could expect the final price of your system to be $6,300 after the discount on the value of the STCs.

Commercial systems and Large-Scale Generation Certificates (LGCs)

When a system of 100kW + is installed, STCs no longer apply. Instead, your system will be eligible to produce LGCs. Your business would be classified as an ‘Accredited power station’.

What are LGCs and how can I access them for my commercial system?

Each year, your business can make a claim for the energy generated by your system. 1MWh (megawatt hour) is equivalent to 1 x LGC. These LGCs can be sold to entities required to offset their emissions in accordance with the Renewable Energy Target.

Unlike STCs, the process of application, claiming, and selling can be a complicated process. The following steps must be followed to generate LGCs:

  1. Apply to become a ‘registered person’ via the REC Registry. A registration fee is required. Only one person in the organisation can be a registered person and this person is responsible for generating LGCs. The application assessment process can take 6 weeks. If successful, your business will become an ‘accredited power station’.
  2. Use the LGC general formula to calculate the LGCs generated in a reporting period.
  3. Update the REC Registry with power station generation data
  4. Create LGCs. This process requires assessment and validation via the REC Registry.
  5. Register the LGCs and pay the LGC creation fee

As you can see, the process is far more laborious than that of STCs but the value of LGCs is greater than STCs. The current value (as of December 2022) for 1 x LGC is $65.

Upgrading an existing commercial solar system

Suppose you upgrade an existing solar system and wish to register as an accredited power station. In that case, the Clean Energy Regulator (CER) will not consider any part of the system that has already received STCs.

For example, if you had an existing 50kW system and claimed STCs, and upgraded to a 150kW system, you would not be able to generate LGCs for 50kW of the 150kW system. You must demonstrate to the CER that you can correctly monitor the output of the separate components to accurately determine the solar generation.

Commercial solar Feed-in Tariff (FiT)

The excess energy generated by your solar system can either be exported to the electricity grid or your business’s solar battery storage. When the energy is exported to the grid, you will receive a financial credit in the form of a FiT. Every kWh exported to the grid will receive a set amount as designated by your solar retailer.

The rate can vary depending on several factors:

  • The rate set by your retailer
  • Whether you are a small, medium, or large business
  • Contracts between your business and a retailer – you may be subject to a higher FiT if you have a special agreement with your retailer


If your business has a rate set at 7 cents/kWh, and you export 20kW in a day, you can expect a credit to your account to the value of $1.40.

Northern Territory

Home and Business Battery Scheme

Eligible Northern Territory businesses can access commercial solar grants of $400 per kilowatt hour of useable battery system capacity, up to a maximum grant of $5,000. The business solar grant can be used for funding to buy and install:

  • a solar photovoltaic (PV) with an eligible battery and inverter
  • an eligible battery and inverter only, if you already have solar PV installed.

You can’t use the funding to buy and install solar PV panels and inverters where they are not being installed simultaneously with a battery.

To receive the business solar grants, businesses must meet the following criteria:

  • Is a Territory Enterprise; and
  • holds a valid Australian Business Number (ABN) which was issued in respect of the business at least 6 months prior to submitting an application.
  • Battery systems to be installed at a property to which a basic connection service is offered by an electricity network provider must be on the HBBS Approved Battery List.
  • Battery systems to be installed at a property to which a basic connection service is not offered by an electricity network provider are not required to be on the HBBS Approved Battery List but must meet all the other requirements at clause 3.2 (see website).
