Your share of a PM-KUSUM solar pump, after subsidy.
Against your own share, not the full project cost.
Diesel avoided less what you pay, in year one.
Sized for a 5 HP pump.
Fuel you no longer have to buy, carry and store.
The subsidy split is indicative.
Central and state subsidy shares under PM-KUSUM are set by scheme guidelines and state orders that change. The share shown here is indicative. Your sanctioned amount is confirmed by NREDCAP when your application is processed.
This is an estimate, not a quote.
This is an estimated range based on average conditions in your area. Your actual numbers depend on site-specific factors we verify before quoting.

- Your pump’s actual fuel consumption, which varies by make and condition
- Borewell depth and discharge, which decide the array you need
- The state subsidy share, confirmed by the nodal agency at sanction
A cost you already pay, every season
Diesel is the clearest case in solar, because the money is already going out. A farmer running a 5 HP pump through an irrigation season is spending a figure they can recognise, and the comparison is against that rather than against an abstract return.
The payback here is measured against your own share after the PM-KUSUM subsidy, not the full project cost. That subsidy split is indicative until the nodal agency confirms it, which is stated on the result and explained in more detail on the pump subsidy calculator.
Questions about this estimate
Is the payback against the full system cost?
No, and deliberately so. It is against your own share after the PM-KUSUM subsidy, because that is the money that actually leaves your hand. Quoting payback on the gross project cost would understate the case considerably for no good reason.
Why do I have to enter the diesel price?
Because it moves constantly, and a price baked into the calculator would quietly falsify every result the week after it was written. Entering today’s price at your nearest pump keeps the comparison honest.
Will a solar pump run as long as my diesel pump?
On an average day, usually yes for the hours that matter. But solar follows the sun: you get more pumping in summer and less in monsoon, and nothing at night. If you irrigate on a fixed schedule regardless of weather, that difference matters and we should talk it through.
What about maintenance?
A solar pump has no fuel to buy, carry or store, and far fewer moving parts than a diesel set. The trade is that the array needs cleaning and the controller is an electronic component that can fail. Over a season the running cost difference is large; over twenty years the maintenance profile is simply different.
