Government Grants & Rebates for Solar and Battery Systems in WAMaximise your savings with clean energy incentives
Government incentives continue to play a major role in reducing the upfront cost of solar panels and battery storage in Western Australia. These incentives are delivered through a combination of federal and state programs and are designed to support the transition to cleaner, more reliable energy systems.
Below is an overview of the current solar and battery rebates available to eligible households and businesses in WA, including key dates, eligibility requirements, and how each incentive works.

What incentives are available?
Federal Incentives
Federal Battery Rebate – Cheaper Home Batteries Program
The federal Cheaper Home Batteries Program commenced on 1 July 2025 and provides an upfront discount of around 30% on the cost of installing eligible battery storage systems.
The program is administered by the Clean Energy Regulator and delivered through Small-scale Technology Certificates (STCs) – the same mechanism used for solar under the SRES. The battery must be installed alongside a new or existing solar PV system.
Key points
- Available for batteries between 5 kWh and 100 kWh usable capacity
- Discount delivered via STCs and applied upfront by your installer
- Battery product must be accredited by the Clean Energy Council and installed by an accredited Solar Accreditation Australia installer
- Battery must be connected to a new or existing solar PV system
- The discount tapers for larger systems and declines over time until 2030
Changes from 1 May 2026
Following amendments to the Renewable Energy (Electricity) Regulations 2001, two important changes took effect on 1 May 2026:
- The STC Factor (which determines how many STCs are created per kWh of usable capacity) now declines every six months rather than annually – from 6.8 (May–Dec 2026) stepping down to 2.1 by the second half of 2030.
- The discount now tapers by battery size: 100% of the STC Factor applies to the first 14 kWh of usable capacity, 60% for capacity between 14 kWh and 28 kWh, and 15% for capacity between 28 kWh and 50 kWh.
These changes are designed to maintain an approximate 30% discount across a range of battery sizes as battery prices continue to fall.
Federal Solar Rebate (Small-scale Renewable Energy Scheme – SRES)
The federal government provides an upfront discount on eligible solar panel systems through the Small-scale Renewable Energy Scheme (SRES), administered by the Clean Energy Regulator.
The discount is applied at the time of installation and is delivered through Small-scale Technology Certificates (STCs). The value of the rebate depends on system size, location, and the year of installation.
Key points
- Applies to residential and small business solar systems up to 100 kW
- Rebate is applied upfront by the installer
- STC values reduce each year until the scheme ends in 2030
- Earlier installation means a higher rebate
- From 2025, the SRES was expanded to also include eligible battery systems via the Cheaper Home Batteries Program
This means households installing solar sooner generally receive a larger discount than those who wait.
State Incentives (Western Australia)
WA Residential Battery Scheme
The WA Residential Battery Scheme provides additional support for Western Australian households installing home battery systems. The scheme is delivered in addition to the federal Cheaper Home Batteries Program and includes both rebates and no-interest loans.
Battery rebates
Eligible households may receive:
- Synergy customers: a rebate of up to $1,300 ($130 per kWh of usable battery capacity)
- Horizon Power customers: a rebate of up to $3,800 ($380 per kWh of usable battery capacity)
The maximum rebate amounts are based on a usable battery capacity of 10 kWh. Batteries with capacity larger than 10 kWh can still participate in the scheme and will receive the applicable maximum rebate amount.
Rebates are applied after installation and are subject to eligibility criteria and program availability.
No-interest loans
Eligible households may also access:
- No-interest loans of up to $10,000
- Loan terms of up to 10 years
- Available to households meeting income and property eligibility requirements
No-interest loans will also be available for up to $10,000 to households with a combined annual income of less than $210,000. Loan repayment periods will be up to 10 years.
To receive a battery rebate and/or no-interest loan through the scheme, eligibility requirements apply, including participation in a Virtual Power Plant (VPP).
Loan availability is limited and subject to assessment and approval.

Combining Federal and State Incentives
In many cases, households may be eligible to combine the federal battery rebate with the WA Residential Battery Scheme, significantly reducing the total installed cost of a battery system.
Eligibility depends on:
- Location
- Electricity retailer (Synergy or Horizon Power)
- Battery size and model
- Household income (for loans)
- Installation timing
Not all systems or households will qualify for every incentive, and program rules may change over time.
Important Notes on Eligibility and Timing
- Incentive values change over time and may be subject to funding caps
- Solar STC rebates decline each year until 2030
- Battery rebate values also reduce gradually over the life of the programs
- Installations must meet current Australian Standards and program requirements
- Only approved products and installers are eligible
For this reason, it is important to assess incentives at the time of quoting rather than relying on general estimates.
Understanding What Applies to Your Home
Government incentives can be complex and vary depending on your circumstances. Battery size, solar system capacity, location, and energy retailer all play a role in determining eligibility and rebate values.
Our team stays across current federal and Western Australian energy policies and can explain how available incentives apply to your property and energy goals.

5 Reasons to Convert to Solar Energy
Unlike conventional power, solar power produces no emissions that harm the environment. It’s a clean, renewable process that uses the most natural of all resources: The Sun.
One of the many myths about solar power involves perceived limitations on the energy-generating potential of solar panels. Solar energy is generated from daylight, not sunlight. So even on cloudy, rainy days, your panels will be working to produce energy. All that energy accumulates in the morning and afternoon hours, the whole time that the sun is up, producing more electricity than you can use.
Many home improvements that you will make won’t add quite the equal value to your house as the money that you put into them. Solar energy, on the other hand, will deliver huge savings on your energy bills each month.
In addition, the investment that you make in solar, will add its exact property value–or more–to your home.
We only install premium quality panels and accessories which carry a 25 year guarantee providing you with peace of mind on your investment.
Solar gets it energy from the Sun which provides ample free energy and is abundant in supply.
