Rebate on Solar Panels: Understand What Support May Apply

Yes. Eligible small-scale rooftop solar installations can continue to receive support through the Australian Government Small-scale Renewable Energy Scheme. The incentive is delivered through Small-scale Technology Certificates rather than a standard government cash payment. In a typical installation, the homeowner assigns the right to create the STCs to a registered agent and receives their value as an upfront reduction in the solar system price. The amount varies depending on the eligible system, location, installation date and certificate value, so there is no single rebate amount that applies to every Australian household.

There is no fixed dollar amount for every installation. The value depends on the number of STCs an eligible solar system can create and the value assigned to those certificates. Important factors include solar system capacity, installation location, installation date, the remaining SRES deeming period and certificate market value. The SRES is scheduled to run until 2030 and certificate entitlement reduces over time, so Decarby calculates the applicable support against the proposed system rather than relying on a generic advertised rebate figure.

Usually not. For most installations, the value of eligible STCs is applied as an upfront reduction in the solar system price after the customer assigns the right to create those certificates to a registered agent. Consumers can potentially create and sell eligible certificates themselves, but that is different from the more common installer-led arrangement. Your solar proposal should clearly show how the applicable incentive has been treated.

Yes. Decarby can review the current federal, ACT and NSW programs relevant to the proposed project and help you understand which incentives may apply. That can include solar STCs, federal battery support, targeted ACT programs and relevant NSW battery incentives. Eligibility still depends on the rules of each government program, the property and the equipment being installed, so we do not treat an advertised incentive as guaranteed before the relevant requirements have been checked.

Eligible ACT concession-card homeowners may qualify for the ACT Home Energy Support Program. The program can provide a rebate equal to 50% of the eligible supply and installation cost of rooftop solar, up to $2,500. Eligible households may also receive another rebate of up to $2,500 for qualifying upgrades such as heating and cooling, heat pump hot water, electric cooking and insulation. This is targeted support rather than a universal ACT rebate available to every Canberra homeowner.

General rooftop solar is no longer a standard eligible product for new applicants under the ACT Sustainable Household Scheme. The scheme continues to provide low-interest finance for eligible batteries and other home-electrification technologies. From 1 July 2026, new eligible applicants can access loans of up to $20,000 with a current standard household interest rate of 3%. Eligible Home Energy Support Program participants may have access to separate finance arrangements for eligible remaining solar costs.

The Australian Government Cheaper Home Batteries Program provides an upfront discount of around 30% on eligible battery systems connected to new or existing solar. Eligible battery systems generally need a nominal capacity between 5 kWh and 100 kWh, while STCs are provided for up to the first 50 kWh of usable capacity. The support calculation changed on 1 May 2026 and now tapers as battery capacity increases. The battery and inverter also need to meet applicable product requirements, and the installation must meet the program’s accreditation and compliance rules.

Sometimes. For example, the NSW Virtual Power Plant incentive can be combined with the Australian Government Cheaper Home Batteries Program when the requirements of both schemes are met. The NSW business battery incentive also allows eligible projects to combine NSW support with applicable federal solar and battery discounts when all conditions are satisfied. Incentive stacking should always be checked for the specific project, because similar-sounding programs can have very different rules around eligibility and double claiming.

BESS1 is an activity within the NSW Peak Demand Reduction Scheme relating to qualifying behind-the-meter battery installations. From 1 July 2026, the activity generally covers batteries from 2 kWh to 28 kWh of usable capacity for specified building and implementation types. It should not be interpreted as a universal additional battery discount for every NSW household, because the previous broad NSW installation incentive was suspended following the launch of the federal Cheaper Home Batteries Program. BESS1 eligibility therefore needs to be checked against the current PDRS rules for the particular project.

BESS2 is the NSW Virtual Power Plant activity. Eligible households and small businesses can receive an incentive for connecting a qualifying battery to a participating VPP. From 1 July 2026, eligible battery systems can be up to 50 kWh, although the capacity used to determine the available incentive is subject to the program’s calculation rules. VPP provider offers and contracts vary, so Decarby recommends considering both the upfront benefit and the longer-term conditions attached to VPP participation.

BESS3 is a NSW Peak Demand Reduction Scheme activity for eligible apartment buildings, available from 1 September 2026. It applies to qualifying apartment buildings with at least four dwellings and generally covers combined usable battery capacity above 20 kWh and up to 200 kWh. NSW Government guidance indicates that eligible apartment projects may receive approximately 30% to 40% off battery installation when the battery is installed together with new or additional solar. Technical, equipment, installation, network and planning requirements also apply.

BESS4 supports eligible battery installations for small and medium businesses and is available from 1 September 2026. The PDRS activity generally covers eligible systems above 20 kWh and up to 200 kWh of usable battery capacity. Businesses may receive a larger incentive when the battery is installed with new or additional solar, subject to program requirements. Before recommending storage, Decarby also looks at the business’s actual energy use, peak demand, operating hours, tariffs and available solar production.

BESS5 is the NSW PDRS activity aimed at larger commercial and industrial battery installations, available from 1 September 2026. Eligible systems are generally above 200 kWh and up to 30,000 kWh of combined usable battery capacity, with incentives applying to the first 10,000 kWh of eligible capacity. Additional technical and connection requirements apply. At this scale, battery storage needs to be assessed against commercial load profiles, tariffs, peak demand, operating schedules and the intended battery-control strategy.

The NSW Virtual Power Plant incentive rewards eligible battery owners for connecting a qualifying system to a participating VPP. The VPP can coordinate participating batteries and make stored electricity available during periods of higher grid demand. Eligible households and small businesses may receive an upfront incentive as well as whatever ongoing arrangements are offered by their chosen VPP provider. The NSW Government states that this incentive can be combined with the federal Cheaper Home Batteries Program where eligibility requirements are satisfied.

Yes. Eligible businesses can potentially access federal STCs for qualifying solar installations and the federal Cheaper Home Batteries Program for qualifying battery systems. NSW businesses may also have access to BESS4 or BESS5 from 1 September 2026, depending on the property, business type, battery capacity and other eligibility conditions. The incentive should still be assessed against the commercial case, because operating hours, interval data, tariffs, peak demand, solar production and expected battery utilisation can have a greater impact on long-term performance than the upfront discount alone.

Potentially. Some federal and state programs can be combined when all eligibility requirements are satisfied, while others contain restrictions designed to prevent two schemes rewarding the same outcome. The correct answer depends on what is being installed, where it is installed, the property type, system capacity, installation date, equipment eligibility, installer requirements and whether another incentive has already been claimed. Decarby reviews the current program settings before multiple incentives are included in project calculations.

No. A rebate on solar panels should not determine solar system size by itself. Solar should be designed around available roof area, shading, electricity consumption, export constraints and future electrical loads. A battery should similarly be designed around available solar surplus, consumption outside daylight hours, tariffs, backup requirements and how the battery will actually operate. The current federal battery program reinforces this principle because the level of support per kWh reduces as battery capacity increases. An incentive can reduce upfront cost, but unnecessary capacity can still represent poor value.

Yes. Government programs are time-sensitive, and eligibility rules, certificate calculations, interest rates, approved products and available incentive levels can change. Recent examples include Cheaper Home Batteries Program changes on 1 May 2026, Sustainable Household Scheme changes on 1 July 2026, NSW PDRS changes on 1 July 2026, and BESS3, BESS4 and BESS5 commencing on 1 September 2026. That is why Decarby checks current official program information when assessing a new project rather than relying on an older rebate article or advertisement.

It can be. Long-term solar value is primarily created by generating electricity your home or business can use and reducing the amount of higher-cost energy purchased from the grid. Government support can improve the upfront economics, but it does not determine whether a solar system is well designed. The same applies to battery storage. Decarby assesses the underlying energy case first and then considers how current incentives improve the project.
