Solar Rebate WA
WA Solar Rebates and Solar Incentives
Solar systems provide clean energy while reducing electricity bills—and in WA, there are financial incentives that help lower the upfront cost of installation.
While WA doesn’t offer traditional panel rebates like some other states, residents can still benefit from the federal Small-scale Renewable Energy Scheme (SRES), which provides Small-scale Technology Certificates (STCs) that reduce the cost of solar systems. Households can also earn credits through the Distributed Energy Buyback Scheme (DEBS) for excess energy exported to the grid.
From 1 July 2025, the WA Government is introducing a Residential Battery Scheme with rebates of up to $5,000 for Synergy customers and $7,500 for Horizon Power customers, plus interest-free loans up to $10,000. On top of this, the federal Cheaper Home Batteries Program will offer a 30% discount on battery system costs, saving eligible households up to $4,000.
With Perth’s high solar potential—over 8 hours of sunlight per day—these combined incentives make now an ideal time to invest in solar and battery storage.
Eligible customers may also be qualified for the Distributed Energy Buyback Scheme (DEBS). This program offers export payment for electricity exported to the grid from rooftop solar, solar batteries, and even electric vehicles.
How Much is the Solar Rebate in Western Australia?
Solar rebate values in WA vary based on your system size, energy usage, and how much power you export to the grid. For a typical 6.6kW system, incentives through STCs can reduce upfront costs by approximately $2,000 to $3,500, with larger systems attracting greater savings.
These rebates are delivered via Small-Scale Technology Certificates (STCs), which fluctuate in value—usually between $34 and $40 each. For an accurate estimate based on your location and system, contact our team today.
Small-scale Technology Certificates (STCs) are one of the most significant incentives for WA residents to go solar. However, the rebate decreases each year as the program gradually phases out, scheduled to end by 2030. To maximise your rebate savings and enjoy lower upfront costs, now is the perfect time to invest in solar power. Don’t miss the opportunity to make the most of these incentives—start your solar journey today!
What are Solar STCs?
Small-Scale Technology Certificates, better known as STCs, are one of Australia’s two federal government incentives. STCs are awarded to individuals who have chosen to install solar panels for their homes.
Before you can get STCs, you must first follow a few guidelines, such as:
- Your solar system should be installed a year before you apply and claim your STCs.
- Parts and accessories of your solar system must be Clean Energy Council-approved.
- All parts should meet strict Australian standards.
- Installation should comply with electrical safety requirements as dictated by the local, state, and federal governments.
- Ensure that you only hire a Clean Energy Council-accredited designer, retailer, and installer.
- Your solar system size should be at most 100kW.
- Your annual electrical output should not go beyond 250MWh for you to claim STCs.
So, how much can you claim? It depends on the supply and demand in the market, but the value will stay under $41 for every certificate.
What Solar Rebates Are Available In Perth?
With rising electricity costs, investing in solar is a smart way to reduce long-term energy bills. In WA, government incentives help lower installation costs and allow you to earn money by selling excess energy back to the grid through the Distributed Energy Buyback Scheme (DEBS).
From 1 July 2025, the WA Government will introduce a new Residential Battery Scheme, offering:
- Rebates of up to $5,000 for Synergy customers and $7,500 for Horizon Power customers
- Interest-free loans of up to $10,000 to assist with upfront battery costs
These incentives make solar and battery storage more accessible, enabling homeowners to store surplus solar power and reduce dependence on the grid.
You can save in three key ways:
- Small-Scale Renewable Energy Scheme (SRES) – Lowers upfront system costs through STCs, based on system size and WA’s strong solar potential
- DEBS – Provides credits for exporting unused electricity back to the grid
- Residential Battery Scheme – Offers added financial support for battery storage, increasing your energy independence
With Perth enjoying over 8 hours of sunlight daily, these combined incentives help you maximise savings and achieve a faster return on your solar investment
Given the rising cost of electricity, solar power continues to be a smart financial decision. Thanks to available government incentives in WA, the cost of installing solar panels is more accessible than ever. These rebates are designed to ease the upfront investment and reward households that generate and export clean energy back to the grid.
You can save in three key ways—through the Small-Scale Renewable Energy Scheme (SRES), the Distributed Energy Buyback Scheme (DEBS), and the upcoming Residential Battery Scheme. While WA may not offer as many direct rebates as some other states, its high solar exposure means you can actually receive greater incentives. The more energy your system generates, the more STCs you can claim. With WA enjoying more sunlight than states like Victoria, this can translate into a larger overall rebate.

What Is The Distributed Energy Buyback Scheme (DEBS)?
What Are the DEBS rates in WA?
The Distributed Energy Buyback Scheme (DEBS) offers time-of-export payments, reflecting electricity costs at different times of the day. Higher rates are paid for electricity exported during late afternoon and evening when demand and wholesale costs are higher.
DEBS rates as of 1 July 2024:
For Synergy customers:
- Peak (3pm to 9pm): 10 cents/kWh
- Off-peak (9pm to 3pm): 2 cents/kWh
These rates encourage using solar energy during the day and installing west-facing panels to generate more energy when demand is high. This helps integrate renewable energy into the grid while maintaining reliability and security.
Who is eligible for DEBS?
Eligible customers include:
- Residential customers consuming no more than 50MWh of electricity annually.
- Schools, universities, and other educational institutions.
- Non-profit organisations.
Eligibility for renewable energy systems:
- Generating capacity between 500W and 5kW.
- A 6.6kW solar PV system with a 5kVa inverter is considered to have a 5kW capacity.
There is no size limit on home or electric vehicle batteries. However, retailers are only required to provide buyback payments for up to 50 kWh per day per premises, exceeding what a 5kW solar PV system typically generates daily.
What Is A
Feed-in Tariffs?
Feed-in Tariffs (FiTs) are tariffs paid to you if you export your excess power to the grid. Like most energy providers, Synergy pays a few cents for each kilowatt-hour (kWh) you give back to the network. This payment comes in the form of a credit on your electricity bill.
The government once offered a FiT up to 60c per kWh. Unfortunately, this program no longer exists for new installations. It is now replaced by a FiT that you negotiate with your energy provider.
In order for you to know how much your FiTs are worth, you need to talk to your electricity retailer. The rate also depends on the wholesale electricity price. If you live in Perth or the southeast metropolitan area, the current FiT is between 2.75c to 10c per kWh. Regional areas with Horizon Energy as their electricity retailer have tariffs worth 3c to 10c per kWh. Also, note that the best time to export is between 3 PM and 9 PM.
If you are not considering getting solar batteries, make sure you benefit from feed-in tariffs to gain passive income from your solar system.
