Solar water pumping systems for farms, institutions and industry
Envotech Energy supplies and installs solar water pumping systems and pump controllers across West Bengal. Solar pumps replace diesel and grid power for irrigation, drinking-water supply and process water, cutting running costs and keeping water flowing where grid supply is unreliable.
- Applications
- Irrigation, drinking & process water
- Configurations
- Surface & submersible
- Supply
- Off-grid or grid-interactive
- Also offered
- Solar water heaters & heat pumps
How a solar pumping system works
Solar modules power the pump directly through a dedicated controller that tracks the available sunlight and adjusts motor speed. Water is pumped during daylight and stored in a tank or delivered straight to the field, so no batteries are needed for most applications.
Where solar pumps work best
Solar pumping is ideal wherever water is needed during the day and grid power is costly, distant or unreliable.
- Agricultural irrigation and farm ponds
- Drinking-water supply for villages and institutions
- Tea gardens, plantations and fisheries
- Process and utility water for industry
Sized for your water requirement
We size the pump, controller and solar array from the daily water requirement, total head, borewell or source depth and seasonal sunlight, so the system delivers the volume you need through the year, not just at peak summer.
Water heating and heat pumps
Alongside pumping, Envotech Energy supplies solar water heaters and heat pumps for hospitals, hotels, hostels and industrial processes that need hot water every day.
Frequently asked questions
Does a solar water pump need batteries?
Usually not. A solar water pump runs directly from the solar modules through a pump controller during daylight hours, and water is stored in a tank or reservoir for use when the sun is not shining.
Can a solar pump replace a diesel pump for irrigation in West Bengal?
Yes. A correctly sized solar pump can replace a diesel pump for daytime irrigation, eliminating fuel costs and reducing maintenance. Farmers may also be eligible for government support schemes such as PM-KUSUM, subject to state implementation and eligibility.
What information is needed to size a solar water pump?
Envotech Energy needs the daily water requirement, the water source (open well, borewell, pond or river), its depth and the total head, the delivery distance, and how the water will be used or stored.
