9,118 solar installations registered with the Clean Energy Regulator · ranked top 10% in Queensland · data current as at 2026-06-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Toowoomba's 9,118 solar systems typically avoid around 56.50 tonnes of CO₂ every hour during peak generation.

Toowoomba is one of Queensland's strongest solar communities, ranking 29th in the state — ahead of 94% of all Queensland postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (565 systems, 11% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Toowoomba's solar community avoids an estimated 90,253 tonnes of CO₂ every year — equivalent to taking 42,978 cars off the road or powering around 18,051 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.
