Pennington ranks 128th 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 87 new systems installed in the past 12 months — a 24% increase on the previous year, making Pennington one of South Australia's faster-growing solar postcodes.
Collectively, Pennington's 1,288 solar systems avoid an estimated 5,824 tonnes of CO₂ per year — the equivalent of removing 2,773 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.
