Marion ranks 168th in South Australia for solar installations — in the middle tier of 347 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 37 new systems installed in the past 12 months — a 42% increase on the previous year, making Marion one of South Australia's faster-growing solar postcodes.
Collectively, Marion's 610 solar systems avoid an estimated 2,758 tonnes of CO₂ per year — the equivalent of removing 1,313 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.
