2,244 solar installations registered with the Clean Energy Regulator · ranked top 50% in Queensland · data current as at 2026-04-03
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Mareeba's 2,244 solar systems typically avoid around 13.90 tonnes of CO₂ every hour during peak generation.

Mareeba ranks 150th in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (195 systems, 6% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Mareeba's solar community avoids an estimated 22,212 tonnes of CO₂ every year — equivalent to taking 10,577 cars off the road or powering around 4,442 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
