Net Metering Savings Calculator

Under net metering, exported units are credited against imported units one-for-one, so an exported unit is effectively worth your retail tariff. Under net billing (or gross settlement), exports are paid at a separate — usually lower — feed-in rate while imports are billed at retail. Which regime applies, and up to what capacity, is set by your state commission and DISCOM, and it changes the economics materially.

Because a self-consumed unit always earns your full landed tariff — it is a unit you did not buy — regardless of settlement regime. Exported units earn the full tariff only under true net metering. A factory running six days a week self-consumes most of its generation; a weekend-heavy or seasonal operation exports more and is more exposed to how the DISCOM settles exports.

Most states cap net-metering eligibility by system size relative to your sanctioned load or contract demand, and several cap it in absolute kW terms too. The caps differ by state and get revised, so we deliberately don't hardcode them here — check your state's current position on our solar policy pages or ask us to verify against the latest DISCOM order.

That depends on your DISCOM's settlement rules: some carry credits monthly and settle annually at a nominal rate, some lapse them, and some pay a defined feed-in tariff. This is exactly the fine print an engineered proposal must read from the current order — assuming credits roll over forever is the most common mistake in vendor projections.
