How it works

Self-use and export value ledger

Value self-consumed solar separately from exported energy using actual period or time-band rates. Count only the portion of export credits expected to be usable or paid, and subtract actual additional charges. This is a supplied-value ledger, not a utility billing engine.

Value = Σ(self-used kWh × avoided import rate + exported kWh × export rate × realizable credit fraction) − additional charges.
