Australian solar rooftop energy storage

Are rooftop solar and behind-the-meter energy storage systems working in Australia?

This is the first edition of a new half-yearly report, monitoring the progress of the deployment of rooftop solar and behind-the-meter energy storage systems in Australia.

Is rooftop solar the fourth-largest source of electricity in Australia?

The Rooftop Solar and Storage Report, developed with data provided by solar consultancy SunWiz, shows rooftop solar is now the fourth-largest source of electricity generation in Australia, providing about 11.2% of the country’s power supply in 2023, eclipsing the 10% mark for the first time.

How many rooftop solar installations are there in Australia?

The growth in rooftop solar has been repeated across Australia, in urban and rural areas, small and large, over the past two decades. There are now 3.5 million rooftop installations across Australia, generating 20,000 gigawatt hours of electricity every year. That's about 8 per cent of all generation in Australia — enough for about 2 million of us.

Where do rooftop solar and battery installation data come from?

The rooftop solar and battery installation data featured in this report is sourced from our data partner for these Rooftop Solar and Storage reports, SunWiz, with supplementary data from Green Energy Markets – the Clean Energy Council’s data partner for our annual Clean Energy Australia report – referenced in some instances.

Why should Australia roll out more rooftop solar and storage?

Rolling out more rooftop solar and storage will help Australia ramp up our renewable energy capacity as our coal-fired power stations continue to close over the coming years. Cutting climate pollution further and faster this decade will help us stem the rapid rise of dangerous global warming and secure a safer future for our kids.

Why is rooftop solar so important in Australia?

Solar — along with wind — is projected to be one of Australia’s most important resources in the quest to generate 82 per cent of the country's electricity using renewables by 2030, and eventually 100 per cent. And as large-scale renewable projects stall, rooftop solar is more important than ever to keep that target on track.
