Mount Gambier sits in the top third of South Australia for solar uptake, ranking 83rd in the state out of 347 postcodes in the Clean Energy Regulator dataset. 130 new systems were added in the past 12 months, with growth of 1% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Mount Gambier's 2,159 solar systems avoid an estimated 9,762 tonnes of CO₂ per year — the equivalent of removing 4,649 cars from the road. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
