Rebates and incentives
Federal and state incentives can cut the upfront cost of solar panels and home batteries. We explain what usually applies in Perth and Fremantle, then show the net price on your quote using current figures.
Based in Hamilton Hill, serving Fremantle and Perth metro
Last reviewed: August 2026. Schemes and amounts change. Your quote uses the rates that apply at that time.
STCs and battery rebates reduce the upfront price, but the amount depends on the product, capacity, installation date and eligibility rules. Compare the final installed price and system specification rather than choosing a quote because its advertised rebate looks larger.
Under the Small-scale Renewable Energy Scheme, eligible rooftop solar systems create Small-scale Technology Certificates (STCs). For most homes the installer assigns those certificates and passes the value through as a point-of-sale discount on the system price.

Eligible heat pump water heaters can also create federal STCs. The number depends on the approved model, installation postcode and current scheme settings. The certificate value is commonly applied as an upfront discount, so your quote should show the current net price rather than relying on an old rebate headline. See our heat pump hot water page for the practical installation factors.

From 1 July 2025 the Australian Government’s Cheaper Home Batteries Program has supported eligible small-scale batteries with a large upfront discount (commonly described as around 30% of eligible battery cost). The saving is meant to go to the customer.

Western Australia also runs a state scheme for residential batteries. It sits on top of federal battery support when you qualify for both. Official WA guidance (updated May 2026) describes:
Most homes across Perth metro are connected through Synergy. We confirm your electricity retailer and eligibility when we quote.

Often yes, when the battery, installer and household meet both programs’ rules. The WA scheme requires an approved product and vendor plus participation in an eligible Virtual Power Plant. Federal eligibility is separate, so both need to be checked against the installation date and proposed equipment.
Rebates cut the upfront cost. Ongoing savings also depend on how much solar you use at home and your retailer’s export rates (for example Synergy DEBS rates by time of day). Feed-in rates are not the same as STC or battery rebates.

Most new rooftop solar systems create federal Small-scale Technology Certificates (STCs). The value is normally applied as a point-of-sale discount on your quote. The amount depends on system size, location zone and the certificate market, and it steps down over time. Your personal quote shows the discount at that date.

Yes, subject to eligibility. The federal Cheaper Home Batteries Program provides a substantial upfront discount on many eligible small batteries (often described as around 30%, with rates reviewed and adjusted over time). Separately, the WA Residential Battery Scheme offers a state rebate for eligible homes: up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers (based on usable capacity, with a typical cap described around 10 kWh). Federal and WA battery support can often be combined when you meet both programs’ rules. We confirm what applies on your quote.
For most residential jobs, the approved retailer or installer manages the STC or rebate application and applies the value to the quote. You still need to meet the property, product and program rules, and the quote should identify each discount separately.
Yes. STC market values move, and the federal battery STC factor now steps down more frequently following the May 2026 changes. WA scheme rules can also be revised. The installation date and current program settings determine the amount used on a quote.
Federal STC and federal battery programs are national. For the WA battery rebate, most metro homes are on Synergy (up to $1,300 under the current state scheme settings). Horizon Power rates apply in Horizon network areas. We check your retailer and eligibility when we quote.
