Net Metering Savings Calculator
Net Metering Savings Calculator — quick estimate
Solar savings are really two numbers: units you self-consume at your full tariff, and units you export at whatever your DISCOM's settlement pays. Split them honestly here — it is the difference between a projection and a surprise.
Your plant & settlement
Assumes 1,500 units/kWp/yr. Set export credit to 100% for true net metering; lower it to model net billing or a feed-in rate. Your state's regime and caps come from the current DISCOM order.

Our team will verify your state's current net-metering position, size the plant to your sanctioned load and send a proposal with the export fine print actually read.

Thanks! Our solar team will verify your DISCOM's current settlement rules and send your working within one business day.
Indicative — settlement regimes, caps and credit carry-over rules are state- and DISCOM-specific and change by order. An engineered proposal reads them from the current regulations for your connection.
Questions engineers and CFOs ask
What is the difference between net metering and net billing?
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.
Why does the self-consumption share matter so much?
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.
Is there a size limit on net metering for my connection?
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.
What happens to unused export credits at year end?
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.
Need an exact BOQ, rate analysis or measurement sheet?
This is a quick engineering estimate. For tendering, billing or audit, our QS & estimation team prepares an item-wise BOQ, rate analysis and a verified measurement sheet to IS / CPWD norms — backed by 15+ years and ISO 9001:2015 quality processes.
