How It Works

How Does Solar Rebate Work?

The rebate amount depends on three things: your system size, location zone, and the current STC market price. Newcastle falls in STC Zone 3, generating approximately 1.185 certificates per kilowatt of installed capacity per year.
With five years remaining in the deeming period (2026 through 2030), the formula yields a meaningful upfront saving.
The STC rate is capped at $40 if sold through the clearing house, though in practice, most installers apply a market price between $38 and $40.
Here's what that looks like across common system sizes:

System Size	STCs Generated	Rebate at $38/STC	Rebate at $40/STC
5kW	34	$1,292	$1,360
6.6kW	45	$1,710	$1,800
7kW	48	$1,824	$1,920
8kW	55	$2,090	$2,200
10kW	69	$2,622	$2,760

Rebates

NSW Battery Rebates and Incentives in 2026

The landscape of the federal government solar battery rebate in NSW changed significantly in July 2025
when the federal government launched the Cheaper Home Batteries Program, and the hardware rebate shifted to a VPP connection incentive.

Federal

Cheaper Home Batteries Program

30% of battery Cost

The Australian Government is funding around a 30% discount on eligible small-scale battery systems connected to new or existing rooftop solar, delivered through the Small-scale Renewable Energy Scheme. The solar battery NSW rebate is applied the same way as the solar panel rebate – straight off your invoice.

NSW

Virtual Power Plant (VPP) Incentive

Up to $1,500

There's also the NSW VPP incentive for households that connect their battery to an approved Virtual Power Plant. The NSW Government updated the Peak Demand Reduction Scheme to complement the Australian Government's Cheaper Home Batteries Program, increasing the incentive available for connecting a battery to a Virtual Power Plant. This VPP incentive can be combined with the federal battery discount.

Federal + NSW

Combined

Up to $5000

Adding battery storage to your solar system unlocks two separate incentives that can be stacked together.

Important Note for 2026

New tiered framework on battery STCs

From 1 May 2026, a new tiered framework applies.

0–14 kWh

100% STC rate

14–28 kWh

60% STC rate

28+ kWh

15% STC rate

For most Newcastle households installing a standard 10–13kWh battery, this has no impact; you stay in the full-rate tier.

The solar power NSW rebate reduces what you pay upfront. Feed-in tariffs (FiTs) reduce what you pay on an ongoing basis by crediting you for excess energy exported to the grid.

What It Means

NSW doesn't mandate a minimum FiT — IPART publishes benchmarks.

NSW doesn't mandate a minimum feed-in tariff. Instead, the Independent Pricing and Regulatory Tribunal (IPART) publishes benchmark ranges to guide what rates households can expect from retailers.
The honest take on feed-in tariffs in 2026: they've dropped significantly from the early days of solar, and the real value of solar is now in self-consumption. When you use your own solar power, you avoid buying grid electricity at roughly 30 cents per kWh. If you export the same kilowatt-hour instead, you might earn around 5 cents. A battery that stores your excess generation for evening use is worth considerably more per kilowatt-hour than exporting it.

Newcastle Typical

A Newcastle home exporting 10–15kWh of surplus daily can add another $400–$700 in annual bill credits through feed-in payments.

Price comparison . Per kWh

A self-consumed kWh is worth ~6× more than one you export.

For the 2025–26 financial year, the IPART all-day benchmark is 4.8 to 7.3 cents per kWh. Some retailers offer higher rates (Origin's Solar Partner Plus plan was offering 12c/kWh up to an export cap as of early 2026), though plans with headline FiT rates often come with higher consumption charges elsewhere.

System capacity

Up to 100 kW. Anything larger falls under the separate Large-scale Generation Certificate (LGC) scheme.

Accredited installer

Must be installed by a Clean Energy Council-accredited installer

Approved equipment

Solar panels and inverter must appear on the CEC's approved products list

One rebate per premises

The rebate applies once per property address

For the solar battery NSW rebate specifically, the battery must be paired with rooftop solar panels, either new or existing. A battery installed without solar is not eligible. The installer must also hold SAA (Solar Accreditation Australia) accreditation.

‍Commercial solar Newcastle businesses are also eligible. Systems under 100kW access the same STC scheme as residential installs, making the rebate equally available for small businesses, offices, and light commercial premises.

Step 1

Get Quotes From CEC-Accredited Installers

All quotes should already show the post-rebate system price. If a quote shows a full price and then deducts the "rebate" separately, that's normal, just confirm the STC calculation is based on your postcode and current deeming period.

Step 2

Sign Your Installation Agreement

When you sign up, you'll assign your STCs to the installer as part of the contract. This is standard practice and gives them the authority to create and sell the certificates on your behalf.

Step 3

Installation Day

Your CEC-accredited installer completes the solar panel installation, signs off on compliance, and submits the STC registration through the REC Registry. You don't need to do anything on this front.

Step 4

Certificate Creation & Sale

The installer creates the STCs through the Clean Energy Regulator's system and sells them, typically to large energy retailers who are legally required to purchase them. The value is already baked into the discount you received

Step 5

Grid Connection

Your network distributor connects your system, you register for a feed-in tariff with your chosen retailer, and your solar starts generating savings from day one.

That's the entire process. There's no government portal, no rebate application form, and no waiting for a payment. The home solar power Newcastle process at Sine Wave Solar follows exactly these steps. We handle all paperwork, including STC registration and network applications, as part of the installation.

How Sinewave Helps

How Does Sine Wave Solar Help You Maximise Your NSW Solar Rebate?

The NSW solar panel rebate in 2026 is worth more when your system is properly sized. An undersized system leaves potential certificate value on the table; an oversized one generates excess you can't use cost-effectively without storage. We've been doing solar and battery installations in Newcastle for over 15 years, and getting the sizing right is the first conversation we have with every client.Here's what we handle on your behalf:

STC Calculation & Registration

We calculate your exact certificate entitlement based on your Newcastle postcode and system size, then register the STCs through the Clean Energy Regulator

Rebate on Battery Storage

If you're adding a battery, we apply both the federal Cheaper Home Batteries Program discount and advise you on the NSW VPP incentive

Network Applications

Grid connection paperwork submitted, so your system can export from day one

$0 Upfront Options

Through our finance partner Brighte, you can install for $0 upfront and offset the repayments with immediate bill savings

Every system we install is CEC-accredited and backed by a 20-year workmanship warranty. We don't use subcontractors – every installation is carried out by our own team.If you want to see what the rebate for solar panels in NSW looks like applied to your specific property, we'll do a free site assessment and bring the numbers to you.

When The Rebate Ends

When Does the Solar Rebate in NSW End?

Year	Deeming Period	STCs (6.6kW)	Rebate ($38/STC)	Lost vs 2026
2025	6 years	54	$2,052	+$342
2026	5 years	45	$1,710	Baseline
2027	4 years	36	$1,368	-$342
2028	3 years	27	$1,026	-$684
2029	2 years	18	$684	-$1,026
2030	1 year	9	$342	-$1,368
2031+	0 years	0	$0	Scheme closed

Waiting a year costs around $342 on a standard 6.6kW system. If you're planning to go solar in the next one to two years, there's a genuine financial reason to move sooner rather than later.

Newcastle Output & Payback

Solar Savings & Payback Period in Newcastle

4.7 peak sun hr/day

Newcastle systems generate more than comparable installations in Sydney's outer suburbs.

28 kWh/day

A typical 6.6kW system in Newcastle generates around 28kWh per day

$1.2–2k/year

Annual bill savings on a solar-only 6.6 kW residential system.

3–5 yrpayback

Solar-only residential payback. 4–7 years with a battery.

Residential

After payback, savings are effectively profit — 20+ more years of free generation, backed by 25-year product warranties on the panels we install.

Commercial

Faster payback, plus tax depreciation.

Commercial solar Newcastle systems also qualify for immediate tax depreciation under the instant asset write-off provisions, a separate financial benefit worth discussing with your accountant.

Looking Ahead

What Happens When Solar Rebates in NSW End?

When the SRES winds up at the end of 2030, new solar installations won't receive an STC discount.
System prices will likely be higher in real terms for buyers who wait.
That said, solar will still be worth installing after 2030;
it's the reduction in up-front cost that disappears, not the ongoing savings from self-consumption and feed-in credits.

Solar STC scheme

The SRES winds up at the end of 2030

Cheaper Home Batteries

The Cheaper Home Batteries Program also runs to 2030, with the discount stepping down every six months from May 2026 onwards

Federal program funding

The Australian Government has expanded program funding to an estimated $7.2 billion

Households supported

Expected to support more than two million Australians installing a battery by 2030. The funding is committed, but the per-unit discount shrinks with each passing period.

For Newcastle homeowners sitting on the fence, the current window (rebate on solar, rebate on battery, NSW VPP incentive on top) is the best combination of incentives available. That combination narrows over the next four years.

Frequently Asked Questions About Solar Rebates in NSW

Is there a $7,000 solar rebate in NSW?

There's no single $7,000 rebate available to NSW homeowners in 2026. The $7,000 figure circulating online typically refers to a combined estimate of the solar STC rebate and battery incentives added together.

Can I get a solar rebate if I already have solar panels?

The STC rebate applies to new installations only. If you already have solar, you won't be able to claim it again for the same system. However, if you're adding a battery to an existing solar system, the Cheaper Home Batteries Program battery rebate is available, provided you use an SAA-accredited installer and the system meets eligibility requirements.

Do I need to apply for the rebate myself?

No. Your accredited installer creates and assigns the STCs on your behalf as part of the installation process. The discount comes straight off your invoice.

Is solar worth it in Newcastle without the rebate?

Yes. The STC rebate reduces your upfront cost, but the ongoing savings from self-consumption of your solar generation are independent of the rebate scheme. At current Newcastle electricity rates, a properly sized system still delivers a strong return over its 25+ year lifespan even after 2030 when the scheme closes.

Are commercial businesses eligible for the solar rebate?

Yes. Systems up to 100kW in capacity qualify for the small-scale scheme. Larger commercial installations participate in the separate Large-scale Generation Certificate scheme. For most small and medium Newcastle businesses, the STC rebate on solar panels in NSW applies the same way it does for residential installs. Our commercial solar Newcastle team can walk through the specific numbers for your premises.

What solar panels qualify for the NSW rebate?

Solar panels and inverters must appear on the Clean Energy Council-approved products list, and installation must be carried out by a CEC-accredited installer. Virtually all quality panels from established manufacturers meet these requirements. At Sine Wave Solar, we only specify Tier 1 panels from manufacturers with a verified track record in Australian conditions and a 25-year product warranty.
