Devonport ranks 39th in Tasmania for solar installations — in the middle tier of 119 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (32 systems, 53% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Devonport's 641 solar systems avoid an estimated 1,332 tonnes of CO₂ per year — the equivalent of removing 634 cars from the road. This is estimated using Tasmania's average grid emissions intensity of 170 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
