Hallett Cove sits in the top third of South Australia for solar uptake, ranking 85th in the state out of 347 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (120 systems, 27% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Hallett Cove's 2,080 solar systems avoid an estimated 9,405 tonnes of CO₂ per year — the equivalent of removing 4,479 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.
