Australia is preparing to lift its ban on plug-in solar and batteries, potentially unlocking the technology for millions of households that currently miss out on rooftop solar.
Energy ministers from across the country met and agreed to explore pathways to support the "safe deployment" of plug-in solar systems. The systems, also known as balcony solar, were legalised in the United Kingdom last month, and New Zealand has flagged plans to do the same within 12 months. Germany leads the world in plug-in solar adoption, with an estimated one in ten households having a system installed.
Currently, plug-in solar can be sold in Australia but cannot legally be plugged in and used. Energy Minister Chris Bowen said a third of Australians already have solar on their roof, making the technology "more popular than the backyard pool."
"Now we're taking the next step, by looking at how even more Australians can take advantage of free, abundant sunshine to cut their energy bills — even if they don't have a roof," Mr Bowen said. "All state and territory ministers are on board and will work with the Commonwealth to look at how plug-in solar and batteries can work in Australia to give apartment dwellers more control over their energy bills."
Plug-in solar systems and batteries can be plugged into regular power points and do not require installation by an electrician. The power generated is fed into the home network via an inverter and a standard plug, offsetting electricity used by appliances. Overseas, they are commonly attached to apartment balconies or installed in backyards, producing between 600 and 800 watts of power at a typical cost of up to $1,300.
Heidi Lee Douglas, CEO of Solar Citizens, a community organisation that has campaigned for legalisation, welcomed the progress. "This commitment to make plug-in solar and plug-in batteries legal in Australia is great news for more than a third of Australians who rent or live in apartments, and also for low-income households so they can access some of the bill-busting benefits that cheap clean solar home owners enjoy," she said. She called for a firm timeline and deadline by the next energy ministers meeting in December.
