Baulkham Hills ranks 298th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (71 systems, 23% below the previous year), a natural slowdown after earlier periods of stronger uptake.

Collectively, Baulkham Hills's 1,019 solar systems avoid an estimated 9,837 tonnes of CO₂ per year — the equivalent of removing 4,684 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.
