2,341 solar installations registered with the Clean Energy Regulator · ranked top 50% in Queensland · data current as at 2026-08-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Mareeba's 2,341 solar systems typically avoid around 14.51 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. 205 new systems were added in the past 12 months, with growth of 1% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Mareeba's solar community avoids an estimated 23,172 tonnes of CO₂ every year — equivalent to taking 11,034 cars off the road or powering around 4,634 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.
