South Australia, the Australian state with the largest number of installed rooftop solar photovoltaic systems, saw a significant rise in on-site solar installations in 2013.
According to reports from utility infrastructure fund and power provider Spark Infrastructure, the state ended the year with 548 MW of rooftop solar on 157,000 rooftops, after beginning the year at 366 MW. Around 21% of Spark’s 750,000 residential customers now have on-site solar systems, the company said.
In addition, the state’s installation rate for rooftop solar doubled in the second half of the year, with 61 MW installed in the first and second quarters of 2013 and 121 MW installed in the third and fourth quarters.
In an interview with Australian renewable energy news site ReNew Economy, Rob Stobbe, CEO of Spark’s South Australian branch SA Power Networks, said the average size of the state’s rooftop solar PV systems has increased from 2 MWh to 4 MWh, and uptake by commercial users is growing.
