- Net metering: imports and exports are netted kWh-for-kWh each month, and non-nettable charges apply to every imported kWh. Net billing: exports earn a money credit that offsets energy charges only, not fixed fees. Feed-in: you pay full price for imports and get the feed-in price for exports.
- Monthly solar shape: SE Europe / US Midwest (≈ 44°). Self-consumption is fixed at 30% of production each month (capped at that month’s use). For an hourly self-consumption estimate, use the solar battery calculator.
- Rules differ by utility and country (netting interval, rollover, minimum bills, taxes on credits). Check your tariff sheet and enter its numbers.
