Solar Rebate Perth

Information last reviewed: 27 August 2026

Rebate programs, certificate values and eligibility rules can change. Confirm the current position with the relevant government authority and an approved retailer before signing a contract.

Solar rebate Perth explained

For rooftop solar, “rebate” usually means the value of STCs

Eligible small-scale solar systems can create Small-scale Technology Certificates under the Australian Government Small-scale Renewable Energy Scheme. In a typical retail transaction, the customer assigns the certificates and their value is shown as an upfront discount in the quote.

Certificate quantity

The number of certificates depends on factors including eligible system capacity, installation date, location and the remaining deeming period under the scheme.

Certificate value

STCs are tradable certificates, so the dollar value applied by a retailer may vary. The written quote should show the assumed discount clearly.

Eligibility conditions

Installer accreditation, approved panels and inverter, installation standards, documentation and timing requirements apply. The retailer should explain customer obligations.

Do not compare headline prices without checking the rebate assumption.

Ask whether the price is before or after STCs, what happens if eligibility is not met, and whether any electrical or site work is excluded.

Australian Government battery support

The federal Cheaper Home Batteries Program may reduce eligible battery costs

The national program operates through the Small-scale Renewable Energy Scheme. The available discount depends on eligible battery capacity, installation date and current program settings. It is generally applied through the retailer or installer rather than paid to the customer after installation.

Questions to ask before relying on the discount

Is the exact battery model and usable capacity eligible on the proposed installation date?
Does the battery need to be connected to new or existing rooftop solar?
What certificate quantity and value are assumed in the quote?
Are backup equipment, switchboard work and communications included separately?

Read the current official program page in the sources below, then discuss the result with the battery installation in Perth team.

Eligible households may also be able to apply for a WA no-interest loan under separate criteria. Finance and rebate eligibility are not guaranteed by a website quote enquiry.

Before signing

Solar rebate Perth quote checklist

Confirm the incentive lines

Ask the quote to separate equipment and installation price, STC or battery certificate discount, WA rebate assumption, optional finance and customer payments.

Confirm exact equipment

Check model numbers, usable battery capacity, inverter arrangement, approved-product status, backup scope and warranty provider.

Confirm site assumptions

Switchboard upgrades, roof access, trenching, metering, communications, wall construction and network requirements can change the final scope.

Confirm what happens if eligibility changes

The contract should explain who carries the risk if program rules, installation timing or eligibility differ from the assumptions used in the price.
