Rajasthan Solar Water Pumping Programme
Distributed solar pumping systems replacing diesel pumps across smallholder farms in an arid district with deep borewells.
Overview
Solar-powered pumping systems for irrigation, drinking water and livestock, engineered for remote sites with no grid or diesel dependency.
A solar water pumping system converts sunlight directly into the energy needed to lift and move water. A photovoltaic array feeds a controller that drives a submersible or surface pump, so water is delivered whenever the sun is shining, with no fuel, no grid connection and very little maintenance.
ARK designs each system around the site: the water source, the total dynamic head, the daily water requirement and the local solar resource. The result is a correctly sized array, controller and pump that deliver the required flow through the year rather than a one-size-fits-all kit.
Systems are built with MPPT controllers that extract maximum power in low light, brushless motors for long service life, and protections against dry-run, overload and reverse polarity. Optional remote monitoring reports flow and system health to a phone or dashboard.

Key benefits
Why customers choose it.
Zero fuel cost
Replace diesel pumps and eliminate recurring fuel and transport expenses.
Daytime irrigation
Water availability follows the sun, matching crop irrigation windows.
Low maintenance
Brushless DC motors and solid-state controllers with no daily servicing.
Grid independent
Works on remote farms and villages with no grid or unreliable supply.
Long service life
Panels typically carry 25-year performance warranties from manufacturers.
Remote monitoring
Optional IoT reporting of flow, power and faults from any location.
Applications
Where it is used.
Agricultural irrigation
Flood, sprinkler and drip irrigation for smallholder and commercial farms.
Drinking water supply
Community and institutional water schemes with overhead storage.
Livestock and dairy
Reliable troughs and washing water for cattle sheds and dairies.
Horticulture
Orchards, nurseries and polyhouses needing precise, scheduled watering.
Aquaculture
Water exchange and aeration support for fish and shrimp ponds.
Institutional campuses
Schools, hostels and health centres in off-grid locations.
How it works
From sunlight to output.
- 01
Sunlight to DC power
The PV array converts sunlight into DC electricity throughout the day.
- 02
Controller optimises
An MPPT controller or VFD tracks maximum power and protects the motor.
- 03
Pump lifts water
A submersible or surface pump draws water from a borewell, well or canal.
- 04
Storage and distribution
Water flows to a tank, canal or drip network sized for the daily requirement.

FAQs
Common questions.
Not answered here? Ask our engineers.
Does a solar pump work on cloudy days?
Yes, at reduced flow. MPPT controllers extract usable power in diffuse light, and systems are sized on annual solar data so seasonal variation is accounted for. Storage tanks bridge low-light periods.
Do I need batteries?
Usually not. Storing water in a tank is far cheaper than storing electricity in batteries. Batteries are only recommended where night-time pumping is essential.
What maintenance is required?
Periodic panel cleaning and an annual inspection of cables, structure and controller. Brushless motors have no brushes or carbon to replace.
Can an existing pump be converted to solar?
In many cases, yes. AC pumps can be driven by a solar VFD. We assess the motor rating, head and daily requirement before recommending conversion or replacement.
Are government subsidies available?
Subsidy schemes for solar pumps vary by state and change over time. Our team can advise on the schemes applicable at your location at the time of enquiry.
