Your 2026 Guide to ACT & NSW Solar and Battery Rebates

If you're a homeowner in Canberra, Queanbeyan or across the ACT and southern NSW, 2026 is shaping up as one of the more interesting years to go solar or add a battery. Between a federal rebate that's actively shrinking every six months, an ACT loan scheme that just crossed 25,000 households, and NSW incentives that stack on top of the federal support, there's a lot of moving parts — and a lot of money on the table if you time it right. Here's what's actually available right now, and how the numbers stack up.

The Federal Solar Panel Rebate (STCs) Hasn't Gone Anywhere

Most people don't realise Australia still has a national solar panel rebate — it's just built into your quote rather than paid out separately. Under the Small-scale Renewable Energy Scheme (SRES), your installer claims Small-scale Technology Certificates (STCs) on your behalf and passes the value straight on as an upfront discount. In 2026 that's worth roughly $248 per kilowatt of panels installed, which works out to around $1,600 off a typical 6.6kW system, or close to $2,500 off a 10kW system. The catch is that this rebate reduces every 1 January until the scheme winds down completely on 1 January 2031 — so the earlier in any given year you install, the more it's worth.

The Cheaper Home Batteries Program — the Big One for 2026

This is the rebate driving most of the interest we're seeing right now. The federal Cheaper Home Batteries Program launched in July 2025 and gives a straight, tiered discount on the cost of a home battery, applied by your installer at point of sale — no separate claim, no waiting for a cheque. As of today it works like this: the first 14kWh of usable storage attracts the full rate (currently around $271 per kWh), the next 14–28kWh is discounted at roughly 60% of that rate (about $162/kWh), and 28–50kWh attracts a smaller 15% rate (about $40/kWh). Batteries up to 100kWh are eligible, but only the first 50kWh of capacity receives any discount.

In dollar terms: a 10kWh battery currently attracts around $2,710 off, a 13.5kWh Tesla Powerwall 3 around $3,660, a 20kWh system around $4,760, and a 30kWh system around $6,140.

Worth knowing: this rebate is deliberately stepping down every six months (not annually, as originally planned) to stretch the federal government's now-expanded $7.2 billion budget out to 2030. Rates were higher in 2025 and again in the first four months of 2026 than they are right now, and they'll step down again before the end of the year. If a battery is on your radar, the rebate you get locked in today is generally better than the one you'll get in six months.

ACT Sustainable Household Scheme — Low-Interest Loans on Top

For ACT residents, the Sustainable Household Scheme (SHS) is the other half of the equation. It's an ACT Government loan — not a grant — but a genuinely useful one: as of July 2026, new applicants can borrow between $2,000 and $20,000 at a flat 3% interest rate, repayable over up to 10 years, to cover batteries, solar hot water and heat pumps, reverse-cycle heating and cooling, electric vehicles and chargers, ceiling insulation, and more. There's no upfront cost, and the loan is arranged through the scheme's finance partner, Brighte, after a short (free) eligibility workshop.

The scheme has clearly found its audience: as of March 2026 it had settled more than 25,000 loans worth over $276 million, and saved Canberra households over $100 million on energy bills between them. Batteries are now the single biggest use of the scheme — just over half of all SHS loans this financial year have gone toward battery systems, up from around 10% before the federal battery rebate landed in July 2025. In practice, most ACT customers we see are using an SHS loan to cover whatever's left after the federal battery rebate and solar STC discount are applied, spreading the balance over several years at a low fixed rate rather than paying it all upfront.

What's Available Across the Border in NSW

If you're just over the border in Queanbeyan or the NSW side of the region, the federal STC and battery rebates apply exactly the same way — but the state-level top-up looks different. NSW doesn't offer a state battery rebate as such; instead, eligible households can earn ongoing incentive payments by connecting a battery (2–28kWh) to a Virtual Power Plant (VPP) under the Peak Demand Reduction Scheme. This generates Peak Reduction Certificates currently worth around $60 per kWh of capacity, which translates to a maximum potential value of around $1,680 for a fully eligible system — though in practice, after your VPP provider and installer take their share, most households end up with somewhere closer to $1,000. It's smaller than the ACT's loan offer, but it stacks on top of the federal battery and solar rebates rather than replacing them, and it keeps paying out over time rather than as a single upfront discount.

Putting the Numbers Together

Here's roughly what it looks like combined. An ACT household installing a 6.6kW solar system with a 10kWh battery today could see around $1,637 off the panels (STC) and around $2,710 off the battery (federal battery rebate) — a combined upfront discount of around $4,350 — with an SHS loan available at 3% to cover the remainder over up to 10 years if needed. A NSW household doing the same install would see the same $4,350 in upfront federal discounts, plus the option to sign the battery up to a VPP for up to roughly $1,000 more in incentive payments over time.

These figures move — the battery rebate steps down again in the coming months, and STC values fall every January — so the numbers above reflect where things stand as of September 2026, not a fixed guarantee.

Getting Started

Because most of these rebates are applied automatically by your installer at the point of sale, the easiest way to find out exactly what you're eligible for is to get a personalised quote that already has the current discounts built in, rather than trying to calculate it all yourself. Our team keeps track of the federal, ACT and NSW settings as they change so your quote always reflects the rebate rates in effect on the day you sign — not last year's numbers, and not next year's reduced ones either.
