Forecasts use Perth solar yield (4.5 kWh/day per kW installed) with a 85% system derate (inverter losses, wiring, soiling), 2025 published WA tariffs (Synergy A1 / Midday Saver / EV Add-On, Horizon R1 / TOU), and the rate-inflation slider you choose for forward years. Self-consumption % is your input; export credits use REBS (7.1c/kWh flat) or DEBS (10c peak / 2c off-peak). All figures inc. GST and exclude one-off install costs — those go in the ROI calculator.
