The Australian Bureau of Statistic (ABS) reports that its latest figures show that 19% of households nationally now currently boast either rooftop solar panels or solar powered hot water systems up from about 5% back in 2011, when the ABS first started publishing statistics on solar.
Of the 19%, 14% of these households have rooftop PV, according to the ABS’s Karen Connaughton.
"Add in solar hot water heating and were up to 19%, so one in five households are now using some form of solar power."
Unsurprisingly, South Australia scored highest for rooftop solar installations, with a huge 24 per cent of households there tapping electricity from the sun.
Queensland is second highest, with 20% rooftop solar penetration, followed by Western Australia with 16%, Victoria with 11%, Australia Capital Territory and New South Wales (NSW) both on 10%, Tasmania at 7% and Northern Territory (NT) at 6%.
The ABS statistics also found that almost all households in Australia (99.7%) used mains electricity as a source of energy, while half used mains gas.
