All Energy Australia fills MCEC each October. What the trade show is, what its 2025 floor said about batteries and panels, and how to read the launches.

All Energy Australia is the country's biggest clean energy trade show, held each October at the Melbourne Convention and Exhibition Centre, and it is the best single place to see which products the industry is betting on for the next two years. In 2025 it drew more than 460 exhibitors, grew its floor space by 30% on the year before, and the loudest message on that floor was home batteries. Our crew goes each year, and we have photos from the 2024 and 2025 shows. This article explains what the show is, what the 2025 floor said, and how a homeowner should read the launch news that comes out of it.

What the show is

All Energy Australia is run by RX Global, part of RELX, in partnership with the Clean Energy Council. The 2026 show ran on Wednesday 28 and Thursday 29 October 2026, 9 am to 5 pm, and general admission was free, with a two day VIP pass at $308. It is a trade event: the people on the floor are installers, electricians, engineers, developers, network businesses, investors and policy people, not the public.

The organiser lists more than 490 suppliers, around 500 speakers and more than 100 conference sessions. The floor is split into zones, including EV technology and infrastructure, energy management and efficiency, and grid and network. The exhibition covers solar, wind, storage, hydrogen, bioenergy and electric transport.

How big it has become

The organiser reports 16,012 unique visitors in 2025, audited and excluding exhibitor staff, up 10% on 2024. pv magazine's report from the floor put total attendance above 17,000, up about 2%, which likely counts differently. Either way it is a big room. The organiser also reports that 29% of attendees hold purchasing authority of $2 million or more, which tells you who the exhibitors are there to meet: wholesalers and installers placing next year's orders.

Results for the 2026 show had not been published when we wrote this, three days after it closed.

What the 2025 floor said: batteries everywhere

The federal Cheaper Home Batteries Program started on 1 July 2025, cutting about 30% off the cost of an eligible home battery. By the time the show opened at the end of October, roughly 100,000 home batteries had been installed under it in under four months, against about a decade for the first 100,000. pv magazine reported the strong interest in battery storage was plain on the floor, in the same year the floor space grew by 30%.

One line from the conference stuck with us. Engie's Ryan Wavish said the "belly of the duck" was already moving later in the day. In plain terms: with so many batteries soaking up midday solar, the cheap middle of the day is stretching into the afternoon, which changes when a battery should charge and which plans suit you. That is the reason we built our energy plan finder, and why the free daytime window plans now matter.

What the 2025 floor said: panels pushing efficiency

The panel makers came to Melbourne to launch, not just to exhibit.

AIKO first unveiled its 500 W Neostar 3P54 at the 2025 show, 25% efficient in the standard residential size. It reached Australian distributors in 2026.
Tongwei, the world's largest solar cell maker, brought its TNC 2.0 range, including a 475 W residential module up to 23.8% efficient.
TW Solar showed a 510 W commercial panel beside its new full black 470 W rooftop panel.

The pattern: more watts from the same 1762 by 1134 mm panel size, and full black, dual glass designs aimed at Australian roofs and hail. Our AIKO field notes and our TW Solar review look at what that means on a real roof.

What the floor says about EV charging, VPPs and heat pumps

The show gives EV technology and infrastructure its own zone, and the energy management zone is where home energy systems, chargers and controllers meet. Virtual power plants and heat pumps sit across the floor rather than in one place.

We would rather not summarise those parts of the floor from memory. What we can say from the products themselves is in our 2026 watchlist, which covers bidirectional chargers and what is and is not available here yet.

How to read the launch news from the show

Every October brings a run of announcements datelined Melbourne. Three rules help sort them.

A launch at the show is not stock in the shed. AIKO's 500 W panel was shown in October 2025 and reached distributors in 2026. Ask when, not whether.
Check the Clean Energy Council listing. A battery that is not on the approved list cannot get the federal discount, whatever the stand says.
Ask who answers the phone. The show floor is full of brands with no Australian office yet. A 25 year warranty is only as good as the local team behind it.

We go to the show to see the gear in person, talk to the engineers rather than the brochures, and come back knowing what to watch. What we fit on your roof still comes down to what is approved, supported locally and right for your site.

If you want to know whether something you read about from the show suits your home or farm, send us a recent bill and your address through our contact page and we will come back to you.

Questions

Can the public go to All Energy Australia?

It is a trade event aimed at industry professionals, though general admission registration has been free. Most homeowners will get more from asking their installer what they saw than from a day on the floor.

When is All Energy Australia?

It is held each October at the Melbourne Convention and Exhibition Centre. The 2026 show ran on 28 and 29 October, and the organiser's site lists 27 and 28 October 2027 for the next one.

How big is All Energy Australia?

The organiser reports 16,012 audited unique visitors in 2025 and more than 490 suppliers listed for 2026. pv magazine counted more than 460 exhibitors and over 17,000 attendees at the 2025 show.

Why do installers go to trade shows?

To see new products before they reach wholesalers, meet the manufacturers' engineers, check build quality in person and hear where the market is heading. It is also where installers learn which brands have real Australian support.
