Campbelltown sits in the top third of South Australia for solar uptake, ranking 38th in the state out of 347 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 257 new systems installed in the past 12 months — a 22% increase on the previous year, making Campbelltown one of South Australia's faster-growing solar postcodes.
The combined impact is substantial: Campbelltown's solar community avoids an estimated 15,463 tonnes of CO₂ every year — equivalent to taking 7,363 cars off the road or powering around 3,093 average Australian homes with clean electricity. 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.
