Queensland Battery Boom: 93% of QVolt Homes Add a Battery

On 11 November 2026, Queensland installer QVolt Solar released its inaugural QVolt Rooftop Report 2026, built from every residential installation the company has completed across 57 council areas in Queensland and northern New South Wales. The headline finding is blunt: 93% of the home solar installs QVolt carried out in 2026 include a battery, up from 63% in 2025 and just 14% in 2024. In two years, the battery has gone from a rare add-on to the default choice on QVolt's roofs.

This is one installer's data, and it should be read that way. QVolt's sample is weighted to south-east Queensland, its northern New South Wales figures are indicative, and commercial jobs are excluded from the report. The figures are shares, averages and indices — install volumes and prices are not disclosed. So the 93% figure is not the Queensland-wide battery rate, and it is not national data. But as a window into what Queensland families are actually deciding when a quote lands on the kitchen table, it is a striking one — and it lines up with the national picture, where the Clean Energy Council reports a record 276,011 home batteries installed across Australia in the first half of 2026, and 153 batteries installed for every 100 rooftop solar systems in that period.

This blog goes deep on the one story: what the QVolt Rooftop Report 2026 found, why the change happened so fast, and what it means for Queensland homeowners, buyers and businesses. The full report, charts and a suburb explorer covering 275 suburbs are available at qvoltsolar.com.au/rooftop-report, and the figures are free to quote with attribution to the "QVolt Rooftop Report 2026".

What happened

QVolt Solar, a Queensland installer, published its first Rooftop Report on 11 November 2026 in Brisbane. The report draws on every residential installation QVolt has completed, across 57 council areas in Queensland and northern New South Wales. It tracks how home solar has changed over 2023 to 2026 — not just how many systems went in, but what was fitted with them: batteries, inverters, panels, hot-water timers and, for the first time, EV chargers.

The central finding is the speed of the battery switch. In 2024, only 14% of QVolt's home solar installs included a battery. In 2025 that rose to 63%. In 2026 it reached 93%. QVolt's Managing Director, Daniel Quinn, put it plainly: "For years a battery was a nice-to-have on roughly one install in ten. Then in July 2025 it became the default, and it hasn't looked back."

The switch happened almost overnight. In June 2025, 54% of QVolt installs included a battery. In July 2025, the figure jumped to 92% — the first month of the federal Cheaper Home Batteries Program. The rate has stayed above 87% every month since. The timing lines up with the federal program starting on 1 July 2025, and the program is the most obvious driver of the jump, but correlation is not proof of sole cause: cheaper cells and bigger units were also landing at the same time, and the report does not claim the program alone caused the change.

The batteries themselves have also grown. The average battery fitted in 2026 holds 23.1 kWh of usable storage, roughly double the 11.4 kWh average of 2024, and 57% of this year's batteries are 20 kWh or larger. Quinn said: "Cheaper cells, bigger units and the federal discount have all landed at once. A 20 kWh battery used to be something you'd see on a big rural property. Now it's a normal choice in Ormeau or Narangba."

Out-of-pocket cost per usable kilowatt-hour of storage, after federal and state rebates and including installation, is 30% lower than in 2023, according to the report. That cost fall, combined with the federal discount, is the other half of the story behind the 93% figure.

The numbers at a glance

The table below brings together the report's headline findings across 2024, 2025 and 2026. Where a figure is only given for some years, that is shown honestly rather than filled in.

Finding	2024	2025	2026
Share of home solar installs including a battery	14%	63%	93%
Average usable battery storage fitted	11.4 kWh	Not stated	23.1 kWh
Share of batteries 20 kWh or larger	Not stated	Not stated	57%
Jobs at homes that already had solar	34%	Not stated	76%
Jobs that are a battery added to an existing system	6%	35%	44%
New solar systems sold with a battery from day one	9%	42%	88%
Average panel wattage	438 W	Not stated	475 W
New systems using a battery-ready hybrid inverter	80%	Not stated	96%
Jobs fitted with a hot-water timer	Not stated	Not stated	4% (52% in 2023)
Installs bundling an EV charger	Not stated	Not stated	1.7%

Two rows in that table deserve a closer look, because they describe a market that has changed its shape, not just its size. First, the second-time solar shift: in 2024, 66% of QVolt jobs were a home's first solar system. In 2026, 76% of jobs are at homes that already had solar. Second, the battery retrofit wave: 44% of all 2026 jobs are a battery added to an existing system, up from 35% in 2025 and just 6% in 2024. Many of the remaining jobs replace small early-2010s arrays. And of the genuinely new solar systems sold in 2026, 88% were sold with a battery from day one, up from 42% in 2025 and 9% in 2024.

In other words, the typical QVolt job in 2026 is no longer a first-time solar install. It is a household that went solar years ago and is now coming back — usually to add a battery, sometimes to replace an ageing array — or a new solar buyer who expects storage from the start.

The panels, inverters and timers behind the shift

The battery boom has reshaped the rest of the system too. Average panel wattage has risen from 438 W in 2024 to 475 W in 2026, so a typical system now uses 19 panels instead of 23 for similar output. Fewer, more powerful panels mean less roof space used for the same generation — useful on Queensland roofs where space, shade and orientation all compete.

Almost every new system is now built ready for storage. In 2026, 96% of new systems use a battery-ready hybrid inverter, up from 80% in 2024. A hybrid inverter is the piece that lets a battery charge from solar and discharge into the home in the evening; fitting one from day one means a battery can be added later without replacing the inverter. The 96% figure suggests installers and buyers alike now treat future storage as a matter of when, not if.

One old solar habit is fading fast. Hot-water timers, fitted on 52% of QVolt jobs in 2023, now appear on just 4% of jobs. The reason is straightforward: timers were a way to soak up daytime solar by heating water while the sun shone. A battery does the same job more flexibly, storing that energy for the evening instead of locking it into hot water. As batteries take over soaking up daytime solar, the timer is becoming redundant.

And a new add-on is appearing for the first time. EV chargers were bundled into 1.7% of 2026 installs. That is a small share, but it is the first time the report records chargers as a bundled item at all, and it points to where the next wave of home-energy spending may go: solar, battery and EV charging bought as one package rather than three separate decisions.

Where the boom is happening

Battery take-up is strongest outside the Brisbane CBD, in the growth corridors and regional centres. Toowoomba leads, with 91% of installs in 2025–26 including a battery, followed by Somerset at 82%, Brisbane City and Moreton Bay at 81% each, and Ipswich at 80%.

The largest share of installs, however, sits in the south-east corner's growth belt. Gold Coast City accounts for the largest share of installs at 22.9%, followed by Brisbane City at 15.6%, Moreton Bay at 13.8% and Logan at 13.6%. The busiest suburbs in 2026 tell the same story: Ormeau, Morayfield, Narangba, Pimpama and Flagstone — growth corridors between Brisbane and the Gold Coast and north to Caboolture, where new estates and young families are moving in. The report's suburb explorer covers 275 suburbs, so a buyer can look up their own area rather than relying on the statewide average.

That geography matters for anyone reading the 93% figure. QVolt's sample is weighted to south-east Queensland, and the busiest suburbs are precisely the places where new homes, new estates and second-time solar buyers cluster. The report describes QVolt's roofs, not every roof in Queensland. A buyer in regional Queensland or in an older Brisbane suburb may face a different mix of installers, roof types and network conditions — which is why local verification matters more than a statewide headline.

Why it happened

Three forces arrived at once, and the report's own numbers point to all three.

• The federal discount: the Cheaper Home Batteries Program began on 1 July 2025, and QVolt's battery share jumped from 54% in June 2025 to 92% in July 2025, the program's first month. The rate has stayed above 87% every month since. The timing lines up, and the program is the most obvious driver — but the report does not prove it was the sole cause, and neither should anyone reading it. Cheaper cells and bigger units were landing at the same time, and buyers were already primed by years of falling battery prices.

• Falling costs: out-of-pocket cost per usable kilowatt-hour of storage, after federal and state rebates and including installation, is 30% lower than in 2023. A battery that cost a household a given amount per kilowatt-hour three years ago now costs materially less for the same usable storage — and the storage itself has doubled, with the average battery rising from 11.4 kWh of usable storage in 2024 to 23.1 kWh in 2026.

• A huge base of existing solar: Queensland has a large stock of homes that went solar a decade ago and are now exporting most of their power for a few cents. Quinn said: "There's a huge base of Queensland roofs that went solar a decade ago and are now exporting most of their power for a few cents. A battery lets them keep that energy for the evening, and that's where most calls are coming from." That explains the retrofit wave: 44% of 2026 jobs are batteries added to existing systems, and 76% of jobs are at homes that already had solar.

There is a fourth factor worth noting, even though the report does not quantify it: expectations have flipped. Quinn said: "Families aren't asking us whether they should get a battery any more. They're asking how big." When buyers stop debating whether to buy and start debating size, the sales conversation changes — and the 57% share of batteries at 20 kWh or larger shows that the size question is being answered with bigger units.

What it changes

The report's findings change the questions a Queensland household should ask before signing a solar or battery quote — and they change the risks of getting the answer wrong.

• Sizing is now the central decision: with 57% of 2026 batteries at 20 kWh or larger, the risk is no longer buying a battery at all, but buying the wrong size. A battery that is too small leaves evening solar unused and savings on the table; a battery that is too large ties up money in storage that rarely cycles fully. Either mistake is harder to fix after installation than before it.

• Retrofits need compatibility checks: adding a battery to an existing system is now the single most common QVolt job type. A retrofit is not the same as a new install: the existing inverter, the age and condition of the panels, the switchboard, the export limit on the connection and the metering all have to work with the new battery. A quote that treats a retrofit like a fresh install can miss those constraints.

• Export limits still apply: a battery reduces how much solar is exported, but it does not remove the network's export limit. Households in south-east Queensland on the Energex network and households in regional Queensland on the Ergon Energy network face different connection arrangements, and the federal program's own settings interact with those limits. Verify the export arrangement on your connection before assuming a battery solves an export problem.

• Timing matters more than it used to: the battery STC factor falls from 6.8 to 5.7 on 1 January 2027, and solar deeming falls from 5 to 4 years on the same date. That changes the value of the federal discount for batteries installed after the change, and it makes the timing of a decision a real cost factor rather than a detail. Verify the current STC settings for your installation date before signing.

• The mid-scale market is opening: the Clean Energy Regulator expanded the Small-scale Renewable Energy Scheme to mid-scale systems of 100 kW to 1 MW from 1 October 2026, with applications opening in mid-to-late November 2026. That is a commercial-scale change rather than a household one, but it sits in the same policy current as the household battery boom, and commercial buyers should be aware of it when planning larger projects.

On the national picture, the Clean Energy Council's figure of 276,011 home batteries installed across Australia in the first half of 2026 — 153 batteries for every 100 rooftop solar systems — confirms that QVolt's experience is not an isolated one. And AEMO's 2026 Integrated System Plan forecasts that two-thirds of solar homes will have a battery by 2050. QVolt's Quinn framed the direction of travel this way: "National numbers tell you how many megawatts went onto the grid. They don't tell you what a family decides at the kitchen table when a quote lands. On our roofs, the battery is already standard on nine installs in ten. That's where the rest of the country is heading." That is a prediction about direction, not a guarantee — and it should be read as one installer's view, not a forecast.

What this means for you

Homeowners who already have solar

• You are the market now: 76% of QVolt's 2026 jobs are at homes that already had solar, and 44% of all jobs are a battery added to an existing system. If your system is from the early 2010s and you are exporting most of your power for a few cents, a battery is the option most Queensland households in your position are now choosing.

• Check retrofit compatibility first: your existing inverter may not be battery-ready, your panels may be nearing the end of their strong-output years, and your switchboard and metering may need work before a battery can be added. A quote that prices only the battery and not the enabling work is incomplete.

• Size against your evening load, not your daytime generation: a battery earns its keep in the evening, when the sun is down and the household load is up. The right size follows your evening usage pattern, not the size of your solar array. Verify your evening load from your bills or your smart meter data before accepting a size recommendation.

• Check your export and feed-in settings: in regional Queensland on the Ergon network, the feed-in tariff is 6.006c/kWh from 1 July 2026. In south-east Queensland on the Energex network, connection summaries are hedged with "confirm your connection approval" wording — verify your connection approval rather than assuming the figure on a quote matches your connection.

Homeowners buying new solar

• Expect a battery in the quote: 88% of new solar systems sold by QVolt in 2026 were sold with a battery from day one, and 96% of new systems use a battery-ready hybrid inverter. If a quote offers solar without storage, or a non-hybrid inverter, ask why — it is now the exception rather than the norm.

• Fewer, bigger panels: with average panel wattage at 475 W, a typical system now uses 19 panels instead of 23 for similar output. Check that the panel count and wattage on your quote match the output promised, and that the roof layout uses the space sensibly rather than simply filling it.

• Ask about the EV charger question now: chargers were bundled into 1.7% of 2026 installs — small, but the first sign of a trend. If you expect to buy an electric vehicle in the next few years, ask whether the system is ready for a charger, even if you are not buying one today.

• Mind the January 2027 change: the battery STC factor falls from 6.8 to 5.7 on 1 January 2027, and solar deeming falls from 5 to 4 years. Verify how the timing of your installation affects the discount you receive.

Commercial and industrial buyers

• The household boom is a signal, not a blueprint: the QVolt report covers residential installs only, and commercial jobs are excluded. Do not apply the 93% household figure to a commercial project. Commercial systems face different export limits, demand profiles, network connection processes and payback logic.

• Watch the mid-scale opening: the Clean Energy Regulator's expansion of the Small-scale Renewable Energy Scheme to mid-scale systems of 100 kW to 1 MW from 1 October 2026, with applications opening in mid-to-late November 2026, is directly relevant to commercial-scale projects. Verify the current application status and eligibility before planning around it.

• Storage sizing is a business case, not a household habit: a commercial battery is sized against tariff structure, demand charges and load profile, not against a neighbour's choice. An independent feasibility assessment is the right step before committing to a commercial-scale battery.

Investors and developers

• The demand signal is real but local: more than 600,000 batteries have been installed under the federal Cheaper Home Batteries Program, as announced on 9 November 2026, and the Clean Energy Council's national figure of 276,011 home batteries in the first half of 2026 confirms strong national demand. But QVolt's 93% figure is one installer's south-east Queensland-weighted sample. Treat it as evidence of direction in one market, not as a statewide or national rate.

• Growth corridors are where the work is: the busiest suburbs in 2026 — Ormeau, Morayfield, Narangba, Pimpama and Flagstone — are growth corridors between Brisbane and the Gold Coast and north to Caboolture. For developers and suppliers, that geography is where residential solar and battery demand is concentrating.

• Policy timing is a risk factor: the STC changes on 1 January 2027 and the mid-scale scheme opening in November 2026 both affect the value and timing of projects. Verify the current settings rather than assuming the conditions of mid-2025 still apply.

What EServices4U would check independently

A headline figure is a starting point, not a decision. Before signing a solar or battery quote in Queensland, EServices4U would check the following independently — and a fixed-fee review exists for each stage of the decision.

• Battery sizing against evening load: is the battery sized to your actual evening usage, or to a round number? A review of your bills and load pattern can show whether a 20 kWh unit, or something smaller or larger, fits your home. This is core to a solar and battery feasibility assessment from $299.

• Retrofit compatibility: will the proposed battery work with your existing inverter, panels, switchboard and metering, or does the quote hide enabling work? A residential solar quote review from $149 checks the quote against your existing system and your connection.

• Export limits and connection approval: what is the export limit on your connection, and does the proposed system respect it? In south-east Queensland, Energex connection summaries are hedged with "confirm your connection approval" wording — verify your approval rather than taking a quote's word for it.

• Panel and inverter specifications: do the panel wattage, panel count and inverter type on the quote match the output and storage-ready claims being made? A 475 W average panel and a 96% hybrid-inverter share are market context, not a guarantee about any single quote.

• Warranty and performance claims: what do the battery, panel and inverter warranties actually cover, for how long, and under what conditions? A quote review checks the warranty wording rather than the sales summary.

• Timing and rebate settings: does the installation date fall before or after the 1 January 2027 STC change, and has the quote applied the right factor? Verify the STC factor and the federal program settings that apply on your installation date.

• For larger projects: commercial and industrial buyers should have the system, the connection and the documentation checked before committing. A Commercial Infrastructure Assessment / RPEQ & RPEV SLD Sign-Off from $495 covers that stage, and Home Owner's Engineer services from $599 support homeowners through a build or a larger residential project.

None of these checks promises a saving or a payback period. They are about making sure the system on the quote is the system you need, at a price that reflects what is actually being supplied.

Frequently asked questions

Does the QVolt report mean 93% of all Queensland homes with solar now have a battery?

No. The 93% figure is the share of home solar installs QVolt carried out in 2026 that included a battery. QVolt is one installer, its sample is weighted to south-east Queensland, and its northern New South Wales figures are indicative. It is not a statewide census and not national data. The national context — 276,011 home batteries installed across Australia in the first half of 2026, according to the Clean Energy Council — supports the direction of the trend, but the Queensland-wide rate is not stated in the report.

Why did battery take-up jump so suddenly in July 2025?

QVolt's battery share rose from 54% of installs in June 2025 to 92% in July 2025, the first month of the federal Cheaper Home Batteries Program, which began on 1 July 2025. The timing lines up and the program is the most obvious driver, but the report does not prove the program was the sole cause — cheaper cells and bigger units were also arriving at the same time. The rate has stayed above 87% every month since July 2025.

How big is the average battery being fitted now?

The average battery fitted by QVolt in 2026 holds 23.1 kWh of usable storage, roughly double the 11.4 kWh average of 2024. More than half of this year's batteries — 57% — are 20 kWh or larger. As QVolt's Daniel Quinn said: "Families aren't asking us whether they should get a battery any more. They're asking how big."

I already have solar. Is adding a battery the right move?

It is the most common move QVolt customers are making: 44% of all 2026 jobs are a battery added to an existing system, and 76% of jobs are at homes that already had solar. Whether it is right for your home depends on your evening load, your existing inverter and panels, your export limit and your feed-in tariff. Verify those four things before deciding, and consider a quote review or feasibility assessment rather than deciding from a single sales quote.

What is the federal Cheaper Home Batteries Program, and is it still running?

The program began on 1 July 2025 and provides a federal discount on home batteries. More than 600,000 batteries have been installed under the program, as announced on 9 November 2026. The battery STC factor falls from 6.8 to 5.7 on 1 January 2027, which changes the value of the discount for later installations. Verify the current settings and your eligibility before signing.

Where are batteries being taken up fastest in Queensland?

Toowoomba leads QVolt's figures, with 91% of installs in 2025–26 including a battery, followed by Somerset at 82%, Brisbane City and Moreton Bay at 81% each, and Ipswich at 80%. The largest share of installs is in Gold Coast City at 22.9%, followed by Brisbane City at 15.6%, Moreton Bay at 13.8% and Logan at 13.6%. The busiest suburbs in 2026 are Ormeau, Morayfield, Narangba, Pimpama and Flagstone.

Do I still need a hot-water timer if I have a battery?

Probably not for the same reason you once did. Hot-water timers were fitted on 52% of QVolt jobs in 2023 and now appear on just 4%, because batteries take over soaking up daytime solar. A timer still has uses in some homes, but it is no longer the default way to use excess daytime solar.
