FAQ

13 kW solar, answered.

How much can a 13 kW system save me?

Up to $4,599* per year at 100% daytime utilisation (Synergy Home Plan A1, 30 c/kWh, 2025). A 13 kW array is the sweet spot for charging a sizeable battery and an EV from the roof.

What rebate applies?

A 13.2 kW installation attracts roughly $4,159 in STC rebate value for 2025 ($3,466 for 2026), applied at point of sale.

Is 13 kW enough to charge an EV?

Typically yes — average EV home charging adds around 10 kWh per day, which a 60 kWh* daily yield comfortably covers alongside household usage.

Do I need a battery with a system this size?

Not strictly, but exports above self-consumption earn far less than energy you store and reuse — most 13 kW buyers add storage now or pre-wire for it.
