1,542 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 1,542 solar systems typically avoid around 7.55 tonnes of CO₂ every hour during peak generation.

Darwin sits in the top third of Northern Territory for solar uptake, ranking 7th in the state out of 46 postcodes in the Clean Energy Regulator dataset. New installations eased in the past 12 months (53 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Darwin's solar community avoids an estimated 12,060 tonnes of CO₂ every year — equivalent to taking 5,743 cars off the road or powering around 2,412 average Australian homes with clean electricity. 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.
