Model different options to see how much you could save on your energy bills
Upload a bill and we'll suggest three scenarios tailored to your usage pattern, peak hours, and household setup.

Forecasts use Perth solar yield (4.25 kWh/kW/day net — Perth 5 PSH × 85% system derate (inverter losses, wiring, soiling)), 2026 published Synergy SWIS tariffs (A1 / Midday Saver / EV Add-On), and the rate-inflation slider you choose for forward years. Self-consumption % is your input; export credits use DEBS (10c peak / 2c off-peak, for new systems) or REBS (7.135c/kWh flat, grandfathered pre-Oct 2020). All figures inc. GST and exclude one-off install costs — those go in the ROI calculator.
