154 solar installations registered with the Clean Energy Regulator · ranked top 50% in Northern Territory · data current as at 2026-08-15
Based on last week's Northern Territory grid mix (avg 640 gCO₂/kWh), Darwin's 154 solar systems typically avoid around 0.75 tonnes of CO₂ every hour during peak generation.

Darwin ranks 20th in Northern Territory for solar installations — in the middle tier of 46 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (5 systems, 62% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Darwin's 154 solar systems avoid an estimated 1,204 tonnes of CO₂ per year — the equivalent of removing 573 cars from the road. This is estimated using Northern Territory's average grid emissions intensity of 640 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
