Oonnati is an affordable, Pay-Per-Use solar irrigation service that provides reliable water access to smallholder farmers without the need for upfront investment. Operated by Oorja, the service deploys solar-powered BLDC and AC submersible pumps capable of irrigating up to 25 acres each. After paying a nominal membership fee, farmers with land near a pump can purchase water on demand at fixed tariffs, paying only for the amount they use. Water is accurately metered using flowmeters and billed on a volumetric basis (per cubic meter), ensuring fair and transparent pricing. Each pump typically serves 15–20 neighboring farmers, offering year-round access to sustainable irrigation.

The Oorja team surveys and selects a suitable site within farmland so nearby farmers can access the pump to irrigate their land, in consultation with the community.
Interested customers sign up by paying a one-time non-refundable membership fee of INR 1,000 per person.
At each prospective site, groups of 15-20 members per pump are formed, and 45 m2 of land is leased at the centre of the farmland for installation of the solar irrigation system.
Oorja constructs borewells and procures, installs, tests and commissions the solar equipment.
A flowmeter is installed at each system to measure the quantity of water dispensed. The pumps are operated between 9 am and 5 pm by a locally hired Pump Operator.
Customers are charged on the day of service by the Pump Operator, based on their individual water consumption, with payment accepted in both cash and online modes.
Oonnati removes the upfront cost burden from farmers, making solar irrigation accessible to the poorest farmers. With year-round access to reliable irrigation, farmers can diversify their crops, adopt high-value crops, expand to a third season, and boost their livelihoods.
Oonnati is priced at least 20% cheaper than diesel-based pumping. It helps farmers save on input costs while guaranteeing year-round water availability, notably during the summer (zayed) season when diesel powered irrigation pumps are often not able to draw groundwater.
