Everything we offer for solar and battery storage in one place — what's included, the kind of work we do, and an instant system size estimate.

Instant Estimate

Size your system in under a minute.

Enter your usage or bill amount for an instant solar and battery size recommendation — then send it straight to us to arrange a site inspection.

1. Tell us your usage

Defaults to a typical SEQ rate — adjust to match your bill.

Include battery storage?

Guide only — assumes 4.5 peak sun hours/day (South East QLD average) and a 18% system derating for inverter and wiring losses. Final sizing depends on your roof, orientation and shading — confirmed at site inspection.

2. Your recommendation

Estimated usage
23.8 kWh/day
Recommended solar system
