Government solar panel rebate in Australia (2026)

The 30-second take

• There is no cheque and no application. The federal rebate is assigned to your installer, who takes it off the price before you ever see a quote.
• On a 6.6 kW system in Sydney it is worth roughly $1,350–$1,700, depending on the certificate price on the day.
• It shrinks every year by design, and the deeming period dropped to 5 years on 1 January 2026 — so the same system is worth less this year than last.
• Your state may add its own money on top. That part does usually involve an application, and it is separate from the federal rebate.
• The batteries scheme is a different rebate with different rules. If your quote covers panels and a battery, two schemes are in play.

Why you can’t find the “solar panel rebate”

Search for it and you land on government pages talking about the Small-scale Renewable Energy Scheme and small-scale technology certificates. Neither phrase appears in any conversation a homeowner has ever had. The thing people mean by "the solar panel rebate" is real, it is federal, and it has a different official name.

Here is the whole shape of it. When a system is installed, it generates certificates based on how much clean electricity it is expected to produce over a set period. Those certificates have a market value. You assign them to your installer, who sells them and takes the value off your price. The rebate arrives as a smaller number on the quote, not as money in your account.

“You do not apply for it, receive it, or see it. You get quoted a price that already has it taken out.”

How much comes off

For the most common Australian residential system — 6.6 kW — the federal rebate is worth roughly $1,650 to $1,750 in Sydney on a 2026 install, at recent certificate prices. Install the same system from January 2027 and it is worth about $1,350: the deeming period drops from five years to four, so the system earns a year fewer certificates. Certificate prices also float on a market, which moves the number again.

Three things move your number: how big the system is, where in Australia it is (the country is split into zones by how much sun they get), and what certificates are trading at that week. The arithmetic behind all three is set out in our STC guide, which is the page to read if you want to check your installer's figure rather than take it on trust.

• Bigger system, bigger rebate. It scales with capacity, so it is not a flat amount per household.
• Sunnier zone, bigger rebate. A system in Darwin earns more certificates than the identical system in Hobart.
• Market price moves it. Certificates are traded, so the value is not fixed by legislation.

It gets smaller every January

This is the part most quotes never mention, and it is the only genuinely time-sensitive thing on this page.

The rebate is calculated over a "deeming period" — the number of years of future generation you get credited for up front. That period steps down each year on the way to the scheme ending, and on 1 January 2026 it dropped to 5 years. Fewer years means fewer certificates means a smaller discount, for exactly the same system on exactly the same roof.

What that does and does not justify: it is a real reason not to leave a decision sitting for eighteen months. It is not a reason to accept a bad quote this week. The difference one step makes is a few hundred dollars on a typical system; a poor installation costs multiples of that.

What your state adds on top

The federal rebate applies everywhere in Australia. Some states then run their own programs, and those genuinely are separate — different eligibility, usually an actual application, sometimes an income test, and frequently a queue or a funding cap.

Two things worth knowing before you go looking. State programs change far more often than the federal one, and several states run no solar-panel program at all and are federal-only. Rather than repeat figures here that would be stale within a month, each state has its own page with the current position.

• Check your state page for what is open right now, what it is worth, and whether there is an income or property-value test.
• Ask whether your installer handles the state application as well as the federal certificates. Many do not.
• Do not assume they stack automatically. Some state programs exclude households that have taken other assistance.

Are you eligible?

For the federal rebate the bar is deliberately low, and it is mostly about the installation rather than about you.

• The system must use approved components and be installed by an accredited installer. This is not a formality — it is the single condition most likely to void the rebate, and it is entirely in your installer's hands.
• There is no income test on the federal rebate. State programs are a different matter.
• It applies to new installations, and there are limits on claiming again for the same premises.
• You need to own the system. Some rent-to-own and power-purchase arrangements assign the certificates elsewhere — worth asking outright if you are offered one.

The “free solar” trap

Because the rebate is invisible and substantial, it is the easiest thing in the industry to sell you twice.

An advertisement offering "free solar" or "government-funded solar" is almost always describing the rebate you were going to get anyway, presented as a gift from the advertiser. The rebate is not the company's to give. Where this gets expensive is when the "free" system is priced so that the rebate covers the discount and the quality comes out of the hardware and the install.

The Clean Energy Regulator inspected 1,278 home battery installations between July 2025 and April 2026 and classified more than 60% as substandard and 1.2% as unsafe — overwhelmingly installation faults on reputable hardware. A rebate-funded discount that arrives with a rushed install is not a saving.

• Ask for the price before and after the rebate. Any decent installer will show you both.
• Compare after-rebate totals only against other after-rebate totals. Mixing the two makes one quote look thousands cheaper than it is.
• Treat "government approved" as meaningless. Accreditation applies to installers and equipment, not to sales claims.

The rebate is the same wherever you buy. The installer is the variable. Get matched with 2-3 vetted solar installers — typically 2+ years in business, with a track record of decent reviews — and ask each of them to show the rebate as its own line.
