4,415 solar installations registered with the Clean Energy Regulator · ranked top 25% in Queensland · data current as at 2026-06-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Hawthorne's 4,415 solar systems typically avoid around 27.36 tonnes of CO₂ every hour during peak generation.

Hawthorne sits in the top third of Queensland for solar uptake, ranking 93rd in the state out of 449 postcodes in the Clean Energy Regulator dataset. 313 new systems were installed in the past 12 months, a 15% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Hawthorne's solar community avoids an estimated 43,701 tonnes of CO₂ every year — equivalent to taking 20,810 cars off the road or powering around 8,740 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.
