Solar Rebates Perth WA 2026: How Much Can You Save?

solar rebates perth wa

In 2026, Perth homeowners can access a solar rebate WA through federal incentives for eligible solar and battery systems, while the WA Residential Battery Scheme adds support for qualifying batteries. Your actual savings depend on the system, battery size, installation date, and eligibility, so compare the final price you pay.

What solar rebates are available in Perth in 2026?

The main incentives are federal support for eligible solar and battery systems and the WA Residential Battery Scheme for qualifying home batteries. There is no single fixed payment that every Perth homeowner receives, which is why rebate estimates can look different from one quote to another.

If you’re researching a solar rebate WA option, first separate solar panels from battery storage. They don’t follow the same incentive rules.

Eligible rooftop solar can receive Small-scale Technology Certificates (STCs), which can generally be used as an upfront discount through a registered agent. Battery systems can also qualify for federal support, while eligible WA households may receive an additional state rebate.

So, rather than asking, “How much is the rebate?” it’s more useful to ask, “How much will my system cost after all eligible incentives?”

How much is the solar battery rebate WA?

The WA Residential Battery Scheme provides a state rebate of up to $1,300 for Synergy customers and $3,800 for Horizon Power customers. The WA rebate is calculated according to usable battery capacity and is capped at 10kWh.  

Federal support can be added to the state amount. For example, the Western Australian Government states that an eligible 10kWh battery can receive combined support of around $5,000 for a Synergy customer. Horizon Power customers can potentially receive more because the WA component is higher. 

These figures shouldn’t be treated as guaranteed savings for every household. Your battery must meet the program requirements, and federal incentives changed during 2026.

Does the WA solar rebate cover solar panels?

No. The WA Residential Battery Scheme is primarily a battery incentive, not a standalone state rebate for rooftop solar panels. Eligible solar installations may still receive federal STC support. 

This is where searches for a solar panel rebate WA can become confusing. Some advertisements use “rebate” as a broad term for several different incentives.

If you’re getting quotes, ask the installer to show:

  • System price: The cost before incentives.
  • Federal incentive: The STC amount being applied.
  • WA incentive: Any state battery support you’re eligible for.
  • Final price: What you will actually pay.

That simple breakdown makes competing quotes much easier to understand.

How does the solar power rebate WA work?

The solar power rebate WA isn’t one universal cash payment. Federal STCs are generally calculated according to the eligible system and installation circumstances, while battery incentives depend on usable battery capacity and the applicable program rules.

For batteries, the federal incentive changed on May 1, 2026. The STC factor became tiered according to battery capacity, with the full factor applying up to 14kWh and lower factors applying to capacity above that threshold. 

That means a larger battery doesn’t automatically produce a proportionally larger incentive.

For homeowners, the practical lesson is simple: don’t choose your battery size based on the rebate alone. Choose it around how much electricity your household actually uses.

What can WA solar rebates save you?

The upfront incentive is only one part of the potential financial benefit. A well-designed solar and battery system can also reduce the amount of electricity your household needs to purchase from the grid.

During sunny hours, your panels can generate electricity for immediate use. Extra energy can be stored in a battery and used later, such as in the evening when household demand increases.

This can make the system more valuable than simply looking at the initial discount.

The right setup depends on your home’s energy habits, not simply the biggest available rebate.

What should you know about the solar panels rebate WA in 2026?

One of the biggest changes this year affects batteries. From May 2026, federal battery STCs began using a tiered structure based on usable capacity. The federal STC factor for May to December 2026 is 6.8, compared with 8.4 for January to April. 

So, if you’ve been reading an older article about battery incentives, its figures may no longer reflect the current calculation.

The Clean Energy Regulator also makes clear that the applicable rebate is determined by the installation date, not simply the date you signed a contract.

Who qualifies for WA solar rebates?

The WA battery scheme is available to eligible Synergy and Horizon Power customers who meet the program requirements. Applicants generally need to be Australian permanent residents and at least 18 years old. The battery must also meet approved product and capacity requirements.

The battery needs at least 5kWh of usable capacity and must be an approved product. Participation in an eligible Virtual Power Plant is also required. This matters because not every battery advertised in Perth will automatically qualify.

How to claim solar rebate WA support?

The process is easier when you use an approved provider and confirm eligibility before installation.

1. Check your eligibility

Confirm your electricity retailer, property circumstances, and whether the battery or solar equipment meets the relevant requirements.

2. Compare installers

Get several written quotes instead of choosing the first company offering a large advertised discount.

3. Check the equipment

For battery support, make sure the proposed battery and associated equipment appear on the relevant approved lists.

4. Review the rebate calculation

Ask when the system will be installed and which federal and WA incentives are included in your quote.

5. Let the provider handle the application

For the WA scheme, the approved battery vendor submits the application on your behalf, with the rebate generally applied as an upfront discount. 

6. Compare the final price

The number that matters most is what comes out of your bank account after eligible incentives, not the biggest rebate figure printed at the top of the quote.

Are solar rebates Perth WA still available?

Yes. The WA Residential Battery Scheme remains available until its planned allocation of 100,000 rebates has been distributed. The WA Government currently expects the scheme to remain available until 2027, although availability depends on the remaining allocation.

That gives homeowners some breathing room, but it doesn’t mean every future installation will receive the same incentive. Federal battery support is already changing over time, so current quotes are more useful than old rebate advertisements.

FAQs

Can I get a rebate for solar panels in Perth?

Eligible rooftop solar can receive federal STC support, which may reduce the upfront installation price. The WA state battery rebate is a separate incentive designed specifically around qualifying battery systems.

What determines the solar battery rebate WA amount?

The solar battery rebate WA amount depends mainly on your electricity provider, usable battery capacity, and whether your system meets the scheme’s eligibility requirements. Eligible Synergy customers can receive a different maximum from Horizon Power customers, with the WA rebate calculated according to usable battery capacity.

Can I combine solar and battery incentives?

Yes, eligible solar and battery systems can potentially receive different forms of federal and state support. However, each component must satisfy the relevant program requirements.

Does a larger battery mean a bigger rebate?

Not necessarily. The WA rebate is capped at 10kWh, while federal battery support uses a tiered calculation for larger systems. A bigger battery should therefore be selected for energy needs rather than rebate size alone.

Can I claim the WA battery rebate myself?

Usually, you don’t submit the WA rebate application directly. An approved battery vendor handles the application on your behalf and applies the eligible rebate as part of the installation process. 

Who is eligible for a solar rebate WA?

Eligibility for a solar rebate WA depends on the type of system, equipment, installation requirements, and the specific government incentive involved. Homeowners should confirm their eligibility with an approved installer before purchasing to understand which rebates or discounts may apply.
