Rooftop solar. Wall-mounted batteries. Homeowner rebates. The clean energy movement in Australia has always been tied to place.
For years, the energy transition has been built on the assumption that independence is something you can bolt down. However, something is brewing that may redefine what it means to “own” your power.
A new generation of technology is emerging that detaches clean energy from fixed infrastructure. Portable batteries like Smartizer and digital solar ownership platforms such as Solarcloud signal the beginning of what could be called nomadic energy: power that follows the person, not the property. In this model, autonomy isn’t reserved for homeowners with north-facing roofs, but extended to anyone with a plug socket or a smartphone.
The implications are profound. Mobility, once energy’s greatest limitation, is fast becoming its defining feature. These systems hint at a future where Australians can carry, trade, or subscribe to power on their own terms, turning clean energy from a household upgrade into a personal asset.
The problem that shaped innovation
For decades, Australia’s clean energy success story has been told through the lens of homeownership. Panels on rooftops became symbols of independence, and by extension, privilege. Yet a third of households rent, and millions more live in apartments where strata rules or limited roof space make solar practically impossible. The clean energy transition, for all its momentum, quietly left a large share of the population watching from the sidelines.
The barrier wasn’t just technical. It was structural. Rebates and incentives were designed for fixed assets—solar systems attached to a property, batteries hardwired into a wall. Portability had no place in policy. Even the national battery rebate, with its 5 kWh minimum capacity, excluded smaller or modular systems that would suit renters or small dwellings. The result was a transition that rewarded ownership, permanence, and space, the very conditions most urban Aussies lack.
This gap created conditions for innovation. As grid costs rise and storage technology matures, the idea of clean energy as something personal has become logical and inevitable. The energy revolution that began on rooftops is now starting to move.
The first generation of nomadic energy systems
Two emerging technologies now show what this new mobility looks like in practice.
The first, Smartizer, offers a plug-in battery designed for renters and apartment dwellers. Compact, stackable, and roughly the size of a suitcase, it stores around 3.5 kWh of power, enough to offset a typical household’s evening load. Instead of seeing an electricity or a permanent installation, users simply connect it to a standard outlet. When they move, the battery moves with them. For the first time, energy storage becomes a possession rather than a fixture.
The second, Solarcloud, redefines ownership in an entirely different way. It allows consumers to buy “blocks” of remote solar generation hosted on commercial rooftops across the country and overseas. Those who invest receive credits on their electricity bills based on the power produced, effectively renting sunlight from afar. It’s solar without the rooftop, a dematerialised model that turns generation into a service rather than a construction project.
Together, these two ideas point to a deeper transformation. Clean energy is no longer anchored to property boundaries or postcode. It’s beginning to detach from geography altogether, favouring use over the grid.
What’s driving the shift
The rise in mobile and virtual energy reflects broader social and economic changes in how Australians live and consume power. Flexibility now defines the modern household. People rent longer, relocate more often, and work remotely. In this context, the traditional model of permanent installations tied to a single address feels increasingly outdated. The technology is simply catching up to the way people already move.
At the same time, the grid itself is evolving toward decentralisation. Power no longer flows neatly from a generator to a socket. Between virtual power plants (VPPs), community batteries, and smart inverters, electricity is becoming a networked ecosystem rather than a one-way service. Portable and off-site systems fit naturally within this distributed logic as they blur the boundaries between producer, consumer, and participant.
Economics play their part too. Battery prices are falling, tariffs are more dynamic, and energy markets are starting to reward flexibility. Charging a portable unit at midday and discharging during peak demand isn’t just convenient, it’s profitable. The shift toward nomadic energy is, at its core, a convergence of lifestyle, technology, and incentive, a sign that autonomy is no longer a luxury reserved for homeowners, but a function of choice.
From fixed systems to fluid networks
As these technologies mature, the idea of the grid itself begins to change. Instead of static infrastructure built around fixed assets, the energy landscape is inching toward a model defined by movement and connection. Portable batteries like Smartizer could act as tiny, flexible nodes within a larger web of storage—thousands of personal devices responding to grid signals, charging when solar output is high and releasing power when demand surges. In aggregate, they could form a distributed stabilising force that complements large-scale batteries and renewable generation.
The same principle applies to virtual ownership. Platforms such as Solarcloud could evolve into digital extensions of community energy networks, where individuals buy into remote generation or pooled resources that feed their local grid. The technology allows participation without proximity as consumers influence supply and demand dynamics from anywhere.
These developments create a picture of fluid energy, which is systems designed to move, adapt, and interact rather than remain tethered to one home or one purpose. They align naturally with hybrid renewable models as one responsive ecosystem. The grid of the future may not be a static structure at all, but a living network shaped by the mobility of its users.
Rethinking policy for a mobile energy future
The current energy policies are built for fixed systems. Rebates, safety standards, and installation rules still assume that batteries are wired into walls and solar panels sit on owned rooftops. As a result, portable batteries and virtual solar platforms fall into regulatory grey zones.
The national battery rebate illustrates the issue clearly. With its 5 kWh minimum capacity, it excludes smaller, modular systems designed for renters or apartment dwellers. Portable units like Smarter, which could make storage accessible to millions, receive no support. Virtual models such as Solarcloud face a similar gap; their users don’t technically “own” a generation system, so they miss out on the same credits and protections offered to traditional installations.
Without policy reform, the transition risks repeating old patterns: rewarding those with property and sidelining those without. Future frameworks will need to follow the consumer rather than the address, recognising that energy participation is shifting from infrastructure ownership to user engagement. Clean energy access will depend on flexibility, and policy must evolve to match it.
Australia’s energy transition is no longer confined to rooftops or property lines. Portable storage and virtual solar ownership mark a quiet but decisive turn toward flexibility. The next wave of independence won’t come from owning infrastructure — it will come from the ability to move with it.
