Solar Rebate WA
WA Solar Rebates and Solar Incentives
Solar systems provide clean energy while helping you save on electricity bills. Beyond these benefits, you can also take advantage of government incentives to reduce the upfront cost of installation.
Although solar prices have dropped significantly over the years, the initial investment remains a concern for many households and businesses. While WA does not offer direct solar rebates like the Northern Territory’s Home and Business Battery Scheme or Victoria’s Solar Panel PV Incentive, there are still financial incentives available.
Western Australians can benefit from Small-Scale Technology Certificates (STCs) under the federal Small-scale Renewable Energy Scheme (SRES), which can significantly reduce the cost of installing a solar system. Additionally, the Distributed Energy Buyback Scheme (DEBS) allows eligible households to earn credits for excess energy exported back to the grid. And don’t forget the long-term electricity savings—Perth enjoys an average of over 8 hours of sunlight per day, helping you achieve a faster return on investment.
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 rebates in WA can vary depending on several factors, including the size of your solar system, the energy you produce and consume, and the amount of excess electricity you export to the grid. Rebate amounts can range from $2,000 to $3,500 for a 6.6kW system, with larger systems typically attracting a higher rebate. Market prices also influence rebate values.
Solar panel financial incentives are provided through Small-Scale Technology Certificates (STCs). Each STC has a fluctuating monetary value, generally between $34 and $40. For a more precise estimate of your rebate, contact our customer support team.
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?
Given rising electricity costs, investing in solar is a smart move. Government incentives in WA help reduce installation costs, and you can also earn money by selling excess energy back to the grid through the Distributed Energy Buyback Scheme (DEBS).
From July 1, 2025, the WA Government plans to introduce a 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 help with upfront battery costs.
These incentives make solar and battery storage more affordable, allowing homeowners to store excess solar power and reduce reliance on the grid.
By investing in solar, you can save in three key ways:
- Small-Scale Renewable Energy Scheme (SRES): Reduces upfront costs based on system size and WA’s high solar generation potential.
- DEBS: Earn credits for exporting excess electricity back to the grid.
- Residential Battery Scheme: Additional support for battery installations, improving energy independence.
With Perth enjoying over 8 hours of sunlight daily, these incentives help you maximise savings and achieve a faster return on investment.
Given the rising costs of electric bills, solar is indeed a smart move. And thanks to government rebates in WA, installing solar has become more attractive than ever. The goal is to help homeowners afford the costs of panels and installation. In addition, you could earn money when you sell your excess energy back to the grid.
By investing in solar, you can save money in three different ways. The first is through the Small-Scale Renewable Energy Scheme (SRES). It is true that solar rebates in WA are not as abundant as in other states and territories. But you can actually get bigger incentives than other locations. That’s because the more power your solar generates, the higher the rebate. With WA receiving more sunshine hours, you can enjoy a larger debate than, say, Victoria.

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.
