You'll cut around 14.2 tonnes of CO₂ every year.

Equivalent to planting roughly 640 trees annually.

Estimates use QLD averages: $0.33/kWh grid rate, $0.06/kWh feed-in, 5 peak sun hrs/day. Your real numbers may vary.

The maths behind your savings

No black box — here's exactly how a Good Frequency system shifts every dollar away from the grid and back into your pocket.

Free fuel from the sun

Every kWh your panels generate is a kWh you don't buy at 33¢. A 10 kW system makes ~1,500 kWh/month in QLD.

Battery shifts day to night

Storing midday surplus and using it after sunset replaces your most expensive grid hours — when rates peak.

Feed-in earns credit

Whatever you don't use gets exported and credited on your bill, further cancelling out your supply charge.
