Fact sheet: Plug-in solar for apartments

Plug-in solar, or balcony solar as it is often called, has become a hot topic.
It’s likely to be an issue that moves quickly, with new tech and new regulation.
Here’s where it stands, and what it means for apartment owners, renters and owners corporations as at October 2026.
What is it?
Plug-in solar is a small kit: one or two panels, a micro-inverter and, increasingly, a battery. It plugs into a standard power point and offsets the electricity your appliances are using at the time. Overseas systems typically produce 600–800 watts and cost up to about $1,300.
At the time of writing, you can buy these kits in Australia (from overseas), but you can’t legally plug them in.
What’s changed?
On Friday 11 September 2026, federal, state and territory energy ministers agreed to explore pathways for the safe use of plug-in solar and batteries, and to report back on next steps by the end of the year.
They’re following a well-trodden path. Around one in ten German households has a system. The UK legalised plug-in solar in August. New Zealand has flagged it will do the same within 12 months.
What does it mean for apartment communities?
Apartment residents and renters have been largely locked out of the solar boom. Research from Energy Consumers Australia shows 50% of owner occupier homes in Australia have solar but only 11% of rental homes and between 3 and 6% of apartments nationally.
Anything that gives people living in apartments a direct way to generate their own power, and take it with them when they move, is a step toward rebalancing the scales.
But that’s not the full story.
Plug-in solar is likely to be a small step forward because it won’t suit every apartment home.
A plug-in system generates only a small fraction of the power of a typical rooftop system. It could work well on a sunny, north-facing balcony. However, on the south side of the building, or in the shadow of the tower next door, the savings shrink fast. It’s a good option for some residents, not a solution for every apartment. In fact it is likely to suit renters in stand-alone homes better than apartments. As Glen Morris from SolarQuip said at an RMIT event: “It’s an answer. Not the answer.”
Safety is central. Strata expert Julie McLean pointed out, “Renewable adoption shouldn’t come at the expense of community safety.” Safety standards need collaborative work. State and federal regulators, along with Standards Australia, need to work together to build a framework that protects the grid, people living in apartments and those on the street below. As an appliance, plug-in solar is no more exotic than the e-bikes, scooters and other battery devices already in our buildings. Germany has made it work, and Australia doesn’t need to start from scratch. Good product and installation standards with clear consumer information will matter — especially for batteries.
Owners corporations will need help to navigate this. Panels mounted on balconies and cabling to power points raise practical questions for OCs, including fixings and wind loading, trip hazards, fire safety, facade appearance, and responsibility if something is damaged or falls. Balconies and facades are often covered by OC rules, and committees may receive requests from residents before national rules are settled. Regulation and clear guidance will help residents and committees work through these questions consistently.
Don’t lose sight of the bigger picture
Plug-in solar is attractive because it’s quick and personal. It scratches an itch for control of our energy use that so many Australians have been locked out of. That’s a strength, and a risk. If it’s treated as the answer for apartments, it could draw attention and effort away from the changes that make the biggest difference over time:
Shared solar and batteries on common property, which can power common areas and share benefits across every lot, whichever way your balcony faces.
Electrifying common systems — central hot water, heating and cooling — where the largest emissions and cost savings usually sit.
Electrifying apartments — moving from gas to efficient electric cooktops, heating and hot water.
EV charging that’s planned for the whole building, not added one bay at a time.
These need decisions by owners corporations, funding and patience but they’re where the big gains are.
What needs to happen
A clear national timeline from energy ministers, with states, territories and Standards Australia working to the same plan.
Borrowing what works: adopting German and UK standards and lessons wherever they fit Australian conditions.
Practical guidance for owners corporations, covering fixings, cabling, fire safety, insurance and by-laws — so committees aren’t left to work it out alone.
Education and guidance for consumers so potential buyers can more easily understand if it’s the right solution for them and their home.
Continued, stronger support for whole-of-building upgrades, so plug-in solar adds to apartment decarbonisation rather than replaces it.
Make sure your committee has current information about plug-in solar so it’s easier to respond when residents ask.
