New technologies could make the switch to solar more affordable for renters and apartment dwellers.
Although Australia boasts high rates of rooftop solar adoption globally, roughly one-third of the population—including renters, apartment dwellers, and individuals on private energy networks—remains largely excluded. These groups encounter obstacles including limited roof availability, expensive switchboard modifications, complex approval timelines, and landlord hesitation since electricity bill reductions favor tenants directly.
Plug-in solar systems, often termed balcony solar because they can be suspended from balcony railings, provide an alternative path for households to handle energy usage. These miniature systems consist of one or two photovoltaic panels connected to a micro-inverter to convert solar energy into electricity, plugging straight into standard wall sockets. Requiring no professional electrical installation, they can be readily set up and taken down, with many models featuring built-in batteries to store surplus power.
Germany spearheads global implementation with over 1.2 million functioning installations, alongside legal adoption in France, Austria, the United Kingdom, and multiple United States regions. Data from the Nationwide Home Energy Rating Scheme Whole of Home tool shows that a vertical, unshaded, north-facing one-kilowatt plug-in setup could lower yearly power bills by Australian $226 in Canberra and $372 in Adelaide, achieving an approximate 13% drop in standard annual energy expenses.
Even with rising attention from policymakers and advocates, operating plug-in solar is currently prohibited in Australia. Resolving this issue involves clearing technical roadblocks, given the absence of certified domestic systems and the need for additional analysis regarding safety, grid consequences, export functions, and household wiring codes.
Additional regulatory challenges arise from Australian tenancy and strata laws that provide landlords and body corporates wide control over building alterations. In contrast, Germany forbids landlords and body corporates from unreasonably denying approval for balcony solar setups solely on aesthetic grounds.
Social barriers further impact vulnerable demographics and renters who seek sustainable housing but encounter information gaps or doubt regarding new technologies. Resolving these challenges necessitates customized approaches developed in collaboration with neighborhood communities.
Meanwhile, Australians have the option to use portable power stations, which are indoor battery devices charged through standard wall sockets that need no clearance from landlords, strata boards, or electricians. These systems store daytime power to run appliances, lighting, and electronic devices.
Initiatives such as the federal Solar Sharer Offer and Victoria's Midday Power Saver supply free midday electricity rates for qualified consumers, aiding those with adaptable daytime energy consumption. For residents with less flexibility, portable power stations make it possible to save this free midday energy for subsequent use, presenting a practical solution for high-rise inhabitants given they receive adequate backing to acquire and run the technology.
