Highbury is one of South Australia's strongest solar communities, ranking 17th in the state — ahead of 95% of all South Australia postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 298 new systems installed in the past 12 months — a 26% increase on the previous year, making Highbury one of South Australia's faster-growing solar postcodes.
The combined impact is substantial: Highbury's solar community avoids an estimated 20,966 tonnes of CO₂ every year — equivalent to taking 9,984 cars off the road or powering around 4,193 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.
