2,603 solar installations registered with the Clean Energy Regulator · ranked top 10% 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 2,603 solar systems typically avoid around 12.74 tonnes of CO₂ every hour during peak generation.

Darwin is one of Northern Territory's strongest solar communities, ranking 4th in the state — ahead of 91% of all Northern Territory postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (89 systems, 16% 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 20,358 tonnes of CO₂ every year — equivalent to taking 9,694 cars off the road or powering around 4,072 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.
