Short answer: no energy retailer in Australia gives you a solar rebate. The real rebate is federal — the Small-scale Renewable Energy Scheme (STCs) for panels, and the Cheaper Home Batteries Program for storage. Your installer claims both on your behalf and discounts the price upfront. Retailers (Origin, AGL, Energy Locals, Amber, etc.) compete on feed-in tariffs, not rebates.

This guide cuts through the marketing language Brisbane homeowners get hit with in 2026 — what the real rebates are worth this year, how the STC step-down affects your timing, what the Cheaper Home Batteries Program actually pays, and how to spot installers who quote "before rebate" prices to look cheap.

The "rebate" you actually get in Brisbane (2026)

There are exactly two rebates available to a Brisbane homeowner installing solar in 2026:

Federal STC rebate (panels) — Small-scale Technology Certificates under the SRES, administered by the Clean Energy Regulator.
Federal Cheaper Home Batteries Program (battery) — launched 1 July 2025, runs to 2030.

That's it. Queensland has no current state-level panel rebate — the QLD Battery Booster scheme closed in 2024, and the federal program replaced it. The 44c Solar Bonus Scheme closed to new applicants in 2012 (existing customers keep it until June 2028). Retailers don't give rebates; they pay you a feed-in tariff for exported energy.

1. The STC rebate explained (the panel one)

Every solar system under 100kW generates STCs based on system size, location (Brisbane is Zone 3), and how many years of generation remain until the scheme ends on 31 December 2030. Each STC trades on an open market — in June 2026 the clearing price is around $36 per STC (it floats between $35–$39.40).

What it's worth on a typical Brisbane install

System size	STCs (Zone 3, 2026)	Approx rebate @ $36
6.6 kW	~67 STCs	~$2,400
10 kW	~101 STCs	~$3,640
13.2 kW	~134 STCs	~$4,820
20 kW (commercial threshold)	~203 STCs	~$7,300

The step-down — why timing matters

The "deeming period" — the number of years of future generation you get credited for upfront — drops by one year every 1 January until 2030. Installed in 2026 you get 5 years of deeming; install the same system in January 2027 and you get 4 years. That's roughly an $480 drop on a 6.6kW system and ~$730 on a 10kW. It is not a discretionary policy — it is hard-coded in the SRES regulations.

Install year	Deeming years	6.6kW rebate	10kW rebate
2026	5	~$2,400	~$3,640
2027	4	~$1,920	~$2,910
2028	3	~$1,440	~$2,180
2029	2	~$960	~$1,460
2030	1	~$480	~$730
2031+	0	Scheme closed	Scheme closed

How you actually receive it

You don't fill in a form. Your CEC-accredited installer assigns the STCs to an STC trader, the trader pays them cash, and the installer passes the discount through on your invoice. A legitimate Brisbane quote in 2026 should read something like: "10kW system $9,800 — less STC rebate $3,640 — $6,160 payable." If a quote just says "$6,160" without showing the rebate line, ask for the breakdown. Some operators quote the after-rebate price to look cheap, then add the STC value back if your roof is shaded or you cancel.

2. The Cheaper Home Batteries Program (the new one)

From 1 July 2025, the federal government extended the SRES to cover home batteries. It's the same STC mechanism, just for storage. The discount works out to roughly $330 per kWh of usable capacity in 2026, with the same annual step-down to 2030.

Eligible batteries: 5 kWh to 100 kWh nominal, one rebate per property.
Must be installed by a CEC-accredited installer and on the CEC-approved product list.
Must be VPP-capable (does not need to be enrolled — just capable).
Can be claimed at the same time as your panel STCs, or retrofitted later.

Battery (usable kWh)	Common products	Approx 2026 rebate
5 kWh	Sungrow SBR064 (partial)	~$1,650
10 kWh	Tesla Powerwall 3, Sungrow SBR096	~$3,300
13.5 kWh	Tesla Powerwall 2/3	~$4,450
16 kWh	Sungrow SBR160, BYD HVM 16.6	~$5,280
20 kWh	Stacked Sungrow / BYD	~$6,600

See our battery cost breakdown for what a Powerwall actually lands at after this rebate in Brisbane.

What energy retailers actually offer (it's not a rebate)

The confusion is understandable — every retailer's marketing copy uses the word "solar" alongside "best deal" — but here's what they actually compete on:

Feed-in tariff (FiT) — cents per kWh exported, often capped at 5–14 kWh/day.
Usage rate — what you pay for imported energy (more important than FiT for most households).
Daily supply charge — fixed daily fee regardless of usage.
Sign-up credits — sometimes $50–$200 bill credit; this is the closest thing to a "rebate" any retailer offers.

None of that money comes from a government scheme. It's the retailer's pricing. For a full Brisbane breakdown including 2026 FiT caps and the Origin/Energy Locals/Amber/AGL math, see our best energy provider for solar guide.

State and council programs in Queensland (2026)

QLD Battery Booster — closed February 2024. The federal program replaced it.
QLD interest-free solar loan — discontinued.
Solar Bonus 44c FiT — closed to new entries July 2012, current holders locked in until 30 June 2028. You cannot inherit it by buying the house — it transfers only to the same NMI under the same owner.
Brisbane City Council — no panel or battery rebate. Some sustainability workshops, that's it.
Energex connection — no charge for standard solar approval (single-phase ≤5kW inverter, three-phase ≤15kW). See our panel sizing guide for inverter limits.

If a QLD-based salesperson tells you about a "Queensland Government rebate" in 2026, they are either confused or misrepresenting the federal STC scheme. Ask them to point to the program on a government website.

The "best rebate" trap — three sales tricks to watch

1. "Free solar with the government rebate" — There is no rebate large enough to make a quality 6.6kW install free in 2026. $2,400 covers maybe 25% of an installed price. Free solar usually means tier-3 panels, no-name inverter, and a finance trap with 15%+ interest dressed up as "interest free for 12 months".

2. "Limited-time bonus rebate from [retailer]" — Retailers don't issue solar rebates. They might offer a sign-up bill credit. Different thing, smaller money, and you usually lose it if you switch within 12 months.

3. "Rebate guaranteed for the next 5 years" — The STC rebate cannot be guaranteed. STC market prices float, and the deeming period drops every January 1. Anyone "guaranteeing" your future rebate value is selling fiction.

How to read a Brisbane solar quote in 2026

A clean, honest quote should show all five lines:

Hardware cost (panels + inverter + mounting + cabling)
Installation labour
STC rebate (number of STCs × $ per STC) — itemised
If applicable: Battery STC rebate (kWh × $ per kWh) — itemised
GST treatment (most residential systems are GST-inclusive on the net figure)

If the rebate line isn't itemised, the installer either doesn't want you to compare on hardware, or is going to claim a different rebate at the back end than they showed at the front.

Frequently Asked Questions

Which energy retailer gives the best solar rebate?

None of them. Retailers don't administer solar rebates — that's the federal Clean Energy Regulator. What retailers offer is a feed-in tariff (paid per kWh exported) plus occasional sign-up bill credits. In Brisbane in 2026, Origin's 22c headline FiT (capped at 14 kWh/day) and Energy Locals' uncapped 5c+ are the most competitive, but the best total outcome depends on your usage rate, not just the FiT.

How much is the federal solar rebate in 2026?

For a Brisbane (Zone 3) install in 2026: roughly $2,400 on a 6.6kW system, $3,640 on a 10kW system, $4,820 on a 13.2kW. Calculated at $36 per STC. The exact figure floats with the STC market price.

Is the solar rebate ending?

Yes — the STC scheme phases out completely on 31 December 2030, and the value drops by roughly 20% every 1 January between now and then. The Cheaper Home Batteries Program also ends in 2030 with a similar step-down.

Does Queensland have its own solar rebate in 2026?

No. The QLD Battery Booster closed in 2024 and was replaced by the federal Cheaper Home Batteries Program. There is no Queensland state-level panel rebate. Anyone claiming a "QLD Government rebate" in 2026 is misrepresenting the federal STC scheme.

How much is the battery rebate in 2026?

Roughly $330 per kWh of usable capacity. A 13.5 kWh Tesla Powerwall 3 lands around $4,450 in rebate; a 16 kWh Sungrow/BYD around $5,280. Battery must be CEC-listed and VPP-capable (does not need to be enrolled in a VPP).

Can I claim both the panel and battery rebate?

Yes — they're separate STC pools under the same SRES umbrella. You can claim both on the same install, or claim the panel rebate now and retrofit a battery later and claim that separately. One battery rebate per property, ever.

Do I lose the rebate if I get a small system?

No — any size from 1kW to 100kW qualifies for STCs proportionally. A 3.3kW system gets roughly half the dollar rebate of a 6.6kW. Below 5kW for batteries you don't qualify for the battery program.

Is the 44c feed-in tariff still available?

Only for QLD customers who signed up before 10 July 2012 and have remained on the same NMI under the same name. It is locked until 30 June 2028. You cannot transfer it by selling the house, upgrading the system above the original kW rating, or moving meters. New installs in 2026 get whatever FiT their retailer offers — typically 4c to 22c.

Why does my quote look more expensive than my neighbour's from last year?

Because the STC deeming period dropped one year on 1 January 2026, reducing the rebate by roughly 20%. A 6.6kW system that cost $4,200 net in 2025 costs ~$4,680 net in 2026 for the same hardware. By 2027 it'll be ~$5,160.

What's the catch with "free solar with the rebate"?

The rebate covers about 25% of an honest install in 2026 — not 100%. "Free solar" deals usually bundle a high-interest finance product (often 13–18% effective) presented as "interest-free for 12 months", with low-tier hardware. You pay 2–3× the cash price over the loan term. See our devil in the detail breakdown.
