Where do you charge? (must total 100%)
Solar charging isn't free — it costs you the feed-in credit you would've earned (default 5c/kWh). That's the honest number, and it's still absurdly cheap.

Consumption presets are realistic mixed-driving figures — highway running at 110 uses 20–30% more. AC charging losses (charger + battery, typically ~10%) are applied to home charging; DC fast-charge billing already includes losses. Doesn't include rego, servicing or battery degradation.
