NSW Solar Rebates 2026: Every Incentive Explained

In 2026, NSW homeowners can access two primary solar incentives: the federal Small-scale Technology Certificate (STC) scheme, which reduces the upfront cost of solar panels by $2,800–$5,500 depending on system size, and the NSW Government's Cheaper Home Batteries Program, which provides a point-of-sale discount of up to $2,200 on eligible home battery installations. Together, these incentives can reduce the combined cost of a solar-plus-battery system by $5,000–$7,000.

Rebate #1: The Federal STC Scheme — Australia's Core Solar Incentive

The Small-scale Technology Certificate scheme is administered by the Clean Energy Regulator under the Renewable Energy (Electricity) Act 2000. It is the cornerstone of solar affordability in Australia and has been responsible for driving solar uptake to over 4 million rooftop systems nationally.

How it works: When a CEC-accredited installer installs an eligible solar system on your home, that system is entitled to generate a number of STCs. These certificates represent the amount of clean electricity the system is expected to generate between its installation date and 31 December 2030. They are sold to electricity retailers — who are legally required to purchase them under the Renewable Energy Target framework — and the proceeds are passed to you as a discount on your installation price.

How much you get: The number of STCs your system generates depends on three factors: system size (kW), your location's solar zone rating, and the number of full years remaining in the scheme. Wollongong and the Illawarra sit in Zone 3 — one of the better zones in NSW. As of 2026, a 6.6kW system in Wollongong generates approximately 82–88 STCs worth around $3,100–$3,400. A 10kW system generates around 125–135 STCs worth approximately $4,700–$5,100.

The phase-out schedule: The STC multiplier reduces by one-fifteenth each year on 1 January. In 2026, you're in "deeming period year 5 of 15." When it reaches year 15 (31 December 2030), the scheme ends and the rebate disappears entirely. Waiting until 2027 to install costs a typical Wollongong household $350–$500 in reduced rebate value. Waiting until 2028 costs more again.

Rebate #2: The NSW Cheaper Home Batteries Program

Launched in mid-2025 by the NSW Government, the Cheaper Home Batteries Program is Australia's most significant state-level battery incentive. It's designed to accelerate battery storage adoption in NSW — both to reduce household electricity costs and to support grid stability as renewable energy penetration increases.

What it offers: A point-of-sale discount of up to $2,200 on the installed cost of an eligible home battery system. Like the STC rebate, the discount is applied upfront by your installer — you pay the net price and the installer claims the subsidy from the Clean Energy Finance Corporation (CEFC) through an accredited retailer program.

Eligibility criteria:

• The property must be a residential dwelling in NSW
• The battery system must be installed by an approved installer under the program
• The battery must meet minimum capacity requirements (typically 2 kWh usable capacity or more)
• The battery can be installed alongside a new solar system or added to an existing one
• There is no income test for the standard subsidy — all eligible homeowners can access it

Additional support for concession holders: Households holding a NSW Pensioner Concession Card or Commonwealth Seniors Health Card may be eligible for additional support under the program. Contact Service NSW or speak to an accredited installer for the most current details on extended eligibility.

Battery brands covered: The program covers a range of CEC-approved battery systems including Tesla Powerwall, BYD Battery Box, Sonnen, Sungrow SBR, and several others. Not all batteries are eligible — verify with your installer that the specific model they're recommending qualifies under the program.

Feed-in Tariffs in NSW: Not a Rebate, But Still Worth Understanding

Feed-in tariffs are not a government rebate — they're a payment from your electricity retailer for excess solar power you export to the grid. However, they're a critical part of the financial picture for any NSW solar owner, so it's worth understanding how they work in 2026.

In the Endeavour Energy network (which covers Wollongong and the Illawarra), voluntary feed-in tariffs are set by individual retailers and currently range from 5–8 cents per kilowatt-hour. The NSW Government abolished the mandatory minimum feed-in tariff for new connections in 2018, so there is no guaranteed floor on what retailers must pay.

Some retailers now offer time-varying feed-in tariffs that pay higher rates during afternoon peak periods (typically 3–9pm) and lower rates at other times. If you're on a standard string inverter setup where you can't control when you export, a flat-rate feed-in tariff may be simpler to manage. If you have a battery and can choose when to export, a time-varying tariff can add meaningful value.

The most important point about feed-in tariffs in 2026: at 5–8¢/kWh, the value of self-consuming your solar generation (at 30–34¢/kWh saved) is four to six times greater than exporting it. Design your system and consumption habits around maximising self-use, not maximising export.

Virtual Power Plants: An Emerging Revenue Stream for Battery Owners

Virtual Power Plants (VPPs) are a relatively new way for households with solar and battery storage to earn additional revenue. In a VPP arrangement, your battery is connected to an aggregator's network, and during high-demand grid events, your stored energy is drawn down and sold into the wholesale electricity market. In return, you receive a share of the revenue — either as bill credits, direct payments, or preferential feed-in tariff rates.

Several VPP programs operate in NSW, including those run by Amber Electric, AGL, and Origin Energy. Participation is voluntary and you can typically withdraw from the program without penalty. The revenue earned through VPP participation varies significantly based on grid conditions, but some households report $200–$600 per year in additional VPP income on top of their regular solar savings.

VPP participation is not a rebate and carries some trade-offs — your battery may be drawn down at times that don't optimise your personal consumption. It's worth understanding the terms before committing, and ensuring your battery always retains a backup reserve for power outages if that capability is important to you.

What Rebates Are NOT Available in NSW in 2026?

It's worth being clear about what doesn't exist, because misleading claims about NSW solar incentives are common in online advertising:

• There is no separate NSW state solar panel rebate in 2026. Some older schemes (like the NSW Government's former solar bonus scheme) are long closed. The NSW Government's current solar-related initiative is the Cheaper Home Batteries Program, which applies to batteries — not panels.
• There is no "emergency" or "limited-time" NSW Government rebate on solar panels. If you see advertising claiming a special NSW rebate is ending imminently and you must call now, it is misleading — likely a high-pressure sales tactic misrepresenting the STC phase-down.
• Council rebates are not available from either Wollongong City Council or Shoalhaven City Council in 2026 for residential solar. Both councils do support solar installations through streamlined approval processes, but there is no direct financial subsidy at the local government level.

How to Claim Solar Rebates in NSW: The Simple Process

For most Wollongong homeowners, claiming rebates is not a separate task you need to manage. Here's how it works in practice:

1. Get quotes from CEC-accredited installers. The STC rebate will already be deducted in the "after rebate" price they quote you.
2. Sign the contract and confirm the installer will handle STC assignment on your behalf (virtually all reputable installers do this as standard).
3. Your system is installed by a CEC-accredited installer using CEC-approved equipment.
4. The installer submits the STC paperwork to the Clean Energy Regulator within 12 months of installation (usually done immediately).
5. You pay the net (after-rebate) price. The rebate value never passes through your hands.

For the Cheaper Home Batteries Program, the same principle applies — the point-of-sale discount is applied by the installer, who is registered as an approved retailer under the program. You do not submit a separate application to the NSW Government.

Frequently Asked Questions

How much is the solar rebate in NSW in 2026?

The federal STC rebate is worth approximately $3,100–$3,400 on a 6.6kW system and $4,700–$5,100 on a 10kW system for Wollongong homeowners in 2026. The NSW Cheaper Home Batteries Program adds up to $2,200 for eligible battery installations. There is no additional NSW-specific rebate for solar panels themselves in 2026.

Is the STC rebate still available in 2026?

Yes — the STC scheme is fully operational in 2026. It phases down by one-fifteenth on 1 January each year and ends on 31 December 2030. The rebate is available to any eligible system installed before that date by a CEC-accredited installer. There is no waitlist, no application, and no limit on numbers.

Do I need to apply for the STC rebate myself?

No. Your CEC-accredited installer handles the STC paperwork and assignment as part of the installation process. You simply pay the net (after-rebate) price shown on your quote. You don't interact with the Clean Energy Regulator or submit any forms yourself.

Who qualifies for the NSW Cheaper Home Batteries Program?

The Cheaper Home Batteries Program is open to NSW residential homeowners installing an eligible battery system through an approved installer. There is no income test for the standard $2,200 discount. Concession card holders may be eligible for additional support. The battery can be added to an existing solar system or installed alongside a new one.

Will I lose the solar rebate if I wait until next year?

Not completely, but you'll receive less. The STC rebate reduces by approximately one-fifteenth on 1 January each year. For a 6.6kW system in Wollongong, waiting until 2027 to install typically costs $350–$500 in lost rebate value. Waiting until 2028 reduces the rebate further. The scheme ends entirely on 31 December 2030.

Can renters or tenants access solar rebates in NSW?

The STC rebate is claimed by the system owner — typically the property owner who pays for the installation. If you rent, you are generally not eligible to claim the rebate yourself unless you have specific arrangements with your landlord. Some advocacy groups are pushing for reforms to allow tenant-initiated solar, and the NSW Government has indicated interest in this area, but no formal scheme existed as of early 2026. Speak to your landlord or property manager if you're interested in solar as a tenant.
