Every solar and battery rebate available in Perth in 2026

Perth households installing solar in 2026 have access to two primary financial incentives — the federal STC program and the WA Battery Scheme — plus a state-backed low-interest loan option. Here's every current program, what it covers, and how to access it.

1 — Small-scale Technology Certificates (federal)

What it is: The main federal solar rebate. Your installer creates and sells STCs on your behalf, reducing the quoted price you pay for the system.

What it covers: Solar panels, eligible inverters, and small wind systems. Does not cover battery storage unless the battery is part of an integrated solar storage system.

How it works: The rebate is already factored into most installer quotes as a "STC discount" — you see a line item reducing the price. You assign your STCs to the installer in exchange for the upfront price reduction.

2026 value:

• Zone 3 (Perth), deeming period: 4 years
• 6.6kW system: approximately 37 STCs × ~$38 = approximately $1,400 rebate
• 10kW system: approximately 56 STCs × ~$38 = approximately $2,130 rebate

STC price fluctuation: STCs trade on a market and the spot price varies (typically $35–$40). Your quoted "STC discount" reflects the price at time of quote.

Who is eligible: Any owner-occupier or investment property owner installing CEC-accredited solar from a CEC-accredited installer. Rental properties are eligible if the landlord installs (they keep the STCs, not the tenant).

Deeming step-down: 4 years in 2026 → 3 years in 2027 → 2 years in 2028 → 1 year in 2029 → scheme ends 1 January 2031.

How to access: Automatically applied by your solar installer in the quote. No application required from you.

2 — WA Battery Scheme (state government)

What it is: A WA state government rebate for adding a battery storage system to a solar installation.

Current terms (2026):

• Amount: $130 per kWh of installed battery capacity
• Maximum rebate: $1,300 (capped at 10kWh of battery capacity)
• Applies to: Batteries installed by Synergy-accredited retailers on premises with a Synergy connection

Eligibility requirements:

• Property must be in Synergy's network area (SWIS — most of the Perth metropolitan area and much of the south-west)
• Must be a residential customer (not commercial)
• Battery must be on Synergy's approved battery list (Small-scale Storage Scheme List — SSL)
• Battery must be installed by an approved retailer

Tesla Powerwall 3 note: The Powerwall 3's integrated inverter-battery design means it is not currently on the Synergy SSL, and is therefore NOT eligible for the WA Battery Scheme rebate. Confirm SSL status for any battery before purchase.

How to access: Your installer (if Synergy-accredited) handles the application. The rebate typically reduces your upfront price or is paid after installation.

Scheme continuation: No scheduled end date as at 2026. Synergy may modify or end the scheme at any time — check synergy.net.au for current status.

3 — Synergy Home Energy Loan (HEEL)

What it is: A Synergy-backed low-interest or interest-free loan for eligible energy efficiency and solar purchases, repaid via your electricity bill.

What it covers (as at 2026): Solar panels, battery storage, heat pump hot water, insulation, and other eligible efficiency upgrades.

Key features:

• Repayments added to your electricity bill — no separate bank loan
• Interest rates are subsidised (verify current rate at synergy.net.au — terms change)
• Available to eligible Synergy residential customers

Practical use: HEEL is best suited for households who want to install solar or battery without a large upfront payment and prefer repaying via their electricity bill. The monthly repayment offsets some of the bill savings from solar.

Limitations: Loan amounts and eligibility criteria are set by Synergy and may change. HEEL may not always be available — check current availability directly with Synergy.

4 — Commonwealth Energy Bill Relief Fund

The federal government's Energy Bill Relief Fund provided direct electricity bill credits to eligible households in 2023–2025. For 2026, check with Synergy whether any continuation of federal bill relief credits applies to your account — credits are typically applied automatically if eligible.

This is a bill credit, not a solar/battery rebate, but it reduces the immediate cost burden while you install solar.

5 — Concessions for low-income and concession card holders

Western Australian electricity concessions (via the Energy Assistance Payment and Hardship Utility Grant Scheme) are income-tested supports for households struggling with energy costs. They are not directly linked to solar installation but can be combined:

• If you're eligible for concessions, you may also be eligible for HEEL on more favourable terms
• Some community energy programs in WA target low-income households for subsidised solar installations — check with Energy Policy WA or Community Services WA for current programs

Stacking the incentives

| Incentive | Maximum value | Can be combined? | |---|---|---| | STCs | ~$1,400 (6.6kW, 2026) | Yes — with all others | | WA Battery Scheme | $1,300 max | Yes — with STCs and HEEL | | Synergy HEEL | Varies | Yes — covers post-rebate cost |

A household installing 6.6kW solar + 10kWh battery in 2026 can receive approximately $2,700 in direct incentives (STCs + battery rebate), then finance the remainder via HEEL if desired.

Rebate amounts, eligibility, and scheme availability as at June 2026. Verify current terms directly with the Clean Energy Regulator (STCs), Synergy (WA Battery Scheme + HEEL), and Energy Policy WA before installation. Rebates may change without notice.
