FAQ

19 kW solar, answered.

How much can a 19 kW system save me?

Up to $6,870* per year under optimal conditions — 100% utilisation, Synergy Home Plan A1 at 30 c/kWh (2025), north-facing at 25° pitch.

What rebate applies?

A 19.8 kW installation attracts roughly $6,239 of STC rebate value for 2025, applied as a point-of-sale discount.

Will I still receive a feed-in tariff at this size?

Systems above 10 kVA inverter capacity per phase may be export-limited or DEBS-exempt. Three-phase properties have more headroom — PSW confirms your network terms before you commit.

Why pair 19 kW with a battery?

At this scale, midday generation far exceeds household load. Storage (and V2X-ready hardware) converts surplus into evening self-consumption instead of low-value exports.
