Solar Pump System Components and Head Pressure
Solar sprinkler pumping systems integrate a photovoltaic solar array, a variable frequency drive (VFD) solar pump controller, and a high-head pump motor.
Unlike flood irrigation pumps requiring only high flow volume, operating sprinkler nozzles demands pumps capable of generating steady working head pressure (two to three kilograms per square centimeter).
- Photovoltaic array: Monocrystalline or polycrystalline solar modules mounted on manual or seasonal tracking structures
- VFD solar inverter controller: Converts variable DC solar voltage into regulated AC power to maintain steady water pressure
- Pump configuration: Multi-stage submersible or high-head surface centrifugal pump tailored for pressurized nozzle operation
- System sizing: Common capacities range from 3 HP, 5 HP, to 7.5 HP solar pumping units
PM-KUSUM Scheme Subsidies and Financial Assistance
Under Component B of the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM), individual farmers receive up to sixty percent capital subsidies on standalone solar pump installations.
State renewable energy development agencies (such as MEDA, HAREDA, RREC) administer online beneficiary applications and empanelled vendor installations.
- Central & state subsidy: Government provides thirty percent central assistance plus thirty percent state subsidy (sixty percent total subsidy)
- Farmer contribution: Farmers pay only ten percent upfront, with remaining thirty percent financed through bank loans
- Target beneficiaries: Small and marginal farmers with existing borewells, open wells, or farm ponds lacking electrical grid connection
Online Application Process and Maintenance Tips
Farmers can apply online through their designated state renewable energy agency portal or state agriculture DBT portal.
Routine cleaning of solar panel glass surfaces with clean water every ten to fifteen days prevents dust accumulation from reducing power output.
- Application portal: Register on official state nodal agency portals under PM-KUSUM Component B
- Required documents: Land revenue records (7/12, RoR), Aadhaar card, bank passbook, and water source certificate
- Panel cleaning: Clean PV panel surfaces in the early morning to maintain maximum solar generation efficiency

Common questions
What subsidy is available for solar water pumps under PM-KUSUM?
Under PM-KUSUM Component B, farmers receive up to 60 percent subsidy (30% central + 30% state) on standalone solar pumps.
Can a solar water pump operate an agricultural sprinkler system?
Yes, solar pumps equipped with multi-stage high-head impellers generate sufficient pressure to run agricultural sprinkler lines smoothly.
Where can farmers apply for subsidized solar pumps?
Farmers can register and apply online through their state renewable energy agency portal (such as MEDA in Maharashtra or HAREDA in Haryana).
