Solar rebates and support in WA
A clear guide to the financial support available when you install solar in Western Australia: the federal scheme that lowers the upfront cost, the WA battery rebate, and the feed-in scheme that credits your exported power.

The short answer
Solar support in WA comes from two levels of government. A federal scheme reduces the upfront cost of solar panels. For home batteries, WA runs its own rebate on top of a separate federal battery scheme, and the two can be combined, which makes WA one of the better states for battery support. WA does not run its own rebate for solar panels. On top of all this, a feed-in scheme credits you for surplus power exported to the grid. Figures are reviewed regularly, so a quote is the best way to know what applies to your system.
The federal scheme for solar panels
The main support that lowers the upfront cost of a solar panel system in WA is a national scheme run by the Australian Government. It applies in WA exactly as it does in every other state.
The scheme works through small-scale technology certificates. When an eligible system is installed, it creates a number of certificates based on the system's size and its expected generation. Those certificates have a market value, and in practice your installer claims them and applies that value as a discount on the price you pay. You do not apply separately, the saving comes off the upfront price at the point of sale.
WA's strong sunshine means systems here generate well, which affects the certificate calculation. The value of the certificates moves with the market, and the scheme reduces over time on a set schedule, so the exact discount on a given system changes. Your installer's quote reflects the rate that applies when you buy.
Support for home batteries in WA
Batteries are where WA stands out. There are two schemes, a national one and a WA one, and they can be claimed together.
The federal battery scheme
The Australian Government runs a national scheme that reduces the upfront cost of an eligible home battery. It uses the same certificate mechanism as the solar panel scheme, your installer claims the certificates and applies the value as a discount. It applies in WA as it does nationally, and the value per unit of storage steps down over time.
The WA battery rebate
On top of the federal scheme, WA runs its own residential battery rebate. It pays a set amount per kilowatt-hour of battery capacity, and the amount depends on whether your electricity provider is Synergy or Horizon Power. To receive it, the battery must join an approved Virtual Power Plant. The detail is in the date-stamped block below.
The WA feed-in scheme
A feed-in scheme credits you for surplus solar power your home exports to the grid. When your panels generate more than your home is using, the excess flows to the grid and you are credited for it on your power bill.
WA's feed-in scheme works differently from a simple flat rate. It uses a time-of-export structure, which means the credit you receive depends on the time of day you export. Power exported during the evening peak, broadly the late afternoon and evening, is credited at a higher rate. Power exported in the middle of the day, when the grid already has plenty of solar, is credited at a lower rate.
The reason this matters is simple. Because midday exports earn relatively little, the better financial move is usually to use your own solar during the day, or store it in a battery for the evening, rather than export it cheaply. This is a large part of why a battery stacks up well in WA. The feed-in scheme is a useful addition on top of self-consumption, not the main benefit.
WA solar support at a glance
The summary below reflects the position as at the date shown. Solar support is reviewed regularly. Always confirm the current detail with your installer when you request a quote.
Last checked: May 2026. The WA Residential Battery Scheme launched on 1 July 2025 and runs until a set number of rebates is reached. Figures, the federal scheme value, feed-in rates and eligibility rules are reviewed and can change. If you are reading this later, confirm the current support before relying on it.

A few practical points help you get genuine value from the schemes rather than just assuming a headline figure.
Use a quote, not a headline
The schemes are applied by your installer at the current rate. A quote shows the real discount, a general figure online may be out of date.
Know your provider
The WA battery rebate differs for Synergy and Horizon Power customers. Your power bill names your provider.
Check the timing
The federal schemes step down over time, and the WA battery scheme runs while funding lasts, so when you buy matters.
Lean on self-consumption
Because WA's feed-in scheme pays less for midday exports, using or storing your own solar usually beats exporting it.
WA solar rebates FAQ
Is there a solar rebate in WA?
The main support for solar panels is a federal scheme that reduces the upfront cost, applied by your installer as a discount. WA does not run its own standalone rebate for solar panels. For home batteries, WA does have its own rebate, the WA Residential Battery Scheme, on top of a federal battery scheme.
How much is the WA battery rebate?
The WA Residential Battery Scheme pays a set amount per kWh of battery capacity. As at May 2026 that is $130 per kWh up to a maximum of $1,300 for Synergy customers, and $380 per kWh up to a maximum of $3,800 for Horizon Power customers. It is capped at 10kWh and applies to approved systems of 5kWh and above, and it can be claimed on top of the federal battery scheme.
Do I have to join a Virtual Power Plant for the WA rebate?
Yes. To receive the WA Residential Battery Scheme rebate, your battery must join an approved Virtual Power Plant, a network that can draw on your battery at times of high demand. The agreement runs for two years, after which you can opt out. An interest-free loan is also available to help cover the remaining cost.
What feed-in tariff will I get in WA?
WA has a time-of-export feed-in scheme. The credit depends on when you export: power sent to the grid during the evening peak earns a higher rate, while power exported in the middle of the day earns less. This rewards using or storing your own solar during the day rather than exporting it cheaply.
Do solar rebates change over time?
Yes. The federal schemes for both solar panels and batteries step down over time on a set schedule. The WA battery scheme runs while its funding lasts, and feed-in rates are reviewed. Because of this, a current quote is the most reliable guide to the support that applies when you buy.
