Send your estimate and a few details — we prepare a real, itemised quote for your property. Free, no obligation.

Estimates only, for planning — your actual result depends on your tariff, roof, usage and the products chosen. Rebate and tariff figures are current as of August 2026: the federal Cheaper Home Batteries Program (tiered per-kWh via STCs), the NSW PDRS battery incentive and the STC discount on new solar all step down on a set schedule, and we confirm the exact value at quote. Verify current values with the Clean Energy Regulator and NSW Government.
