Self-consumed kWh = min(production, consumption). Excess is exported; shortfall is imported. Bill with solar = imported × retail − exported × export rate.
Practical Example
Utilities differ on credit rates and time-of-use. Some regions use net billing at wholesale export rates—enter your actual export $/kWh.
