Australia reaches 4.59 GW of small-scale solar PV

Australia continues to lead the world in deployment of rooftop solar PV. As of December 1 the nation had reached 1.49 million small-scale PV installations, according to data released by the nation’s Clean Energy Regulator.

With an average system size of 3.08 kilowatts (kW) this means 4.59 GW of small-scale PV. Clean Energy Finance Corporation estimates that the nation will have another 300 MW of large-scale PV by the end of the year. With a population of 24 million, this means 203 watts of solar PV per resident – well below that of Germany, which has more large-scale solar, but well above the global average.

During 2015 119,000 small-scale PV systems were installed in Australia, roughly 1/3 of the market volume in 2011 and 2012. Since 2012, Australia’s solar PV market has declined steadily.Queensland has led deployment of small-scale PV in 2015 with 34,500 new installations, followed by New South Wales with 27,900 and Victoria with 25,500.

In September, the Energy Supply Association of Australia published a report which finds that 15% of residential buildings in the nation have rooftop solar PV – by far the highest portion in the world.
