Galston ranks 318th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. 72 new systems were added in the past 12 months, with growth of 3% on the previous year — typical of a maturing market where most interested households have already installed.

Collectively, Galston's 887 solar systems avoid an estimated 8,563 tonnes of CO₂ per year — the equivalent of removing 4,078 cars from the road. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
