640 solar installations registered with the Clean Energy Regulator · ranked top 25% in Northern Territory · data current as at 2026-04-03
Based on last week's Northern Territory grid mix (avg 640 gCO₂/kWh), Darwin's 640 solar systems typically avoid around 3.13 tonnes of CO₂ every hour during peak generation.

Darwin sits in the top third of Northern Territory for solar uptake, ranking 10th in the state out of 46 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (29 systems, 3% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Darwin's 640 solar systems avoid an estimated 5,005 tonnes of CO₂ per year — the equivalent of removing 2,383 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.
