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. 73 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, Pennington's 1,261 solar systems avoid an estimated 5,702 tonnes of CO₂ per year — the equivalent of removing 2,715 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.
