Nearly 2.5GW of PV capacity had been installed on just over one million domestic and business rooftops in Australia as of the end of March 2013, according to the country's Clean Energy Regulator.
Australia's Clean Energy Council ascribes the five-year boom (the country had just 20,000 PV systems in 2008) to government incentives and falling system costs.
Indeed, Queensland, the state with one of the more generous feed-in-tariff schemes, continues to have the lion’s share of installed capacity with approximately 771MW of PV power. New South Wales comes second with approximately 536MW.
According to figures from the CEC, 1,000,643 rooftop PV systems have been registered under the country’s Renewable Energy Target (RET) scheme. The Clean Energy Council’s CEO David Green said this translates to about 2.5 million Australians living in homes with solar panels.
