Solar Surface Water Pump System

Solar Surface Pump Overview

Solar surface pump is a water extraction device powered by solar energy. Solar panels convert solar energy into direct current (DC) electricity, while the controller regulates the current and voltage to ensure stable system operation. Typically equipped with Maximum Power Point Tracking (MPPT) functionality, it optimizes the output of the solar panels. This type of pump is primarily used to draw water from surface water sources such as rivers, lakes, shallow wells, or ponds. It is suitable for a variety of applications including agricultural irrigation, household water supply, and livestock watering. The solar surface pump transforms solar energy into electrical energy to drive the pump, achieving efficient and environmentally friendly water extraction.

Applications for Solar Powered Surface Water Pump

Agricultural Irrigation, Farming / Crop Cultivation

Solar surface water pumps are ideal for agricultural irrigation in remote areas with limited access to electricity. They provide a sustainable and cost-effective solution to deliver water to crops, fields, and orchards using solar energy. Those solar surface pumps are commonly used to draw water from surface or reservoirs for farming. They support consistent water supply for rice fields, vegetable plots, and greenhouses, helping farmers increase yields sustainably.

Livestock Watering

Solar surface water pumps are an excellent solution for providing consistent and reliable water sources to livestock in remote areas where grid power is unavailable or unstable. Solar-powered livestock watering systems can reduce manual labor, eliminate fuel costs, and require minimal maintenance. Many ranchers use solar surface pumps  to draw water from surface or lake directly to troughs or storage tanks.

Domestic Water Supply

In off-grid rural homes or remote villages, solar powered surface water pumps offer a sustainable and dependable solution for everyday water needs. Whether it's drawing water from a deep well for drinking, showering, laundry, or gardening, solar submersible pumps and well pumps can be installed with minimal infrastructure. These systems are especially beneficial in areas with limited or unreliable electricity, empowering families with access to safe and consistent water.

Solar surface pumps are ideal for driving fountains, offering a sustainable and low-maintenance solution for water circulation. They harness solar energy to power water features, reducing electricity costs and environmental impact.

Solar motor surface pumps are excellent for pond aeration, promoting healthy aquatic ecosystems. By oxygenating the water, they support fish and plant life, improving overall pond health and water quality.

Solar Panels Calculation for Solar Powered Surface Water Pump

It's recommended that the solar panel has a power rating 1.3 -1.5 times greater than the water pump's power. Additionally, ensure the voltage of the solar array matches the voltage requirements of the water pump.
For example:
VEICHI DC Solar Water Pump
Power: 750W
Optimum input voltage: 90-120V
Maximum open circuit voltage: 160V
Recommended solar panel power ≥1.3*750w (power≥975w)
VMP(voltage at max) voltage >90v
VOC voltage <160v
Solar panels

• Power 330 watts

• VMP voltage 37.26v

• VOC voltage 45.64v

3 solar panels connected in series

• Power 330w*3=990w

• VMP voltage 37.26v*3=111.78v

• VOC voltage 45.64v*3=136.92v

In this case, the power and voltage requirements of the water pump can be met, so this solar PV panel array solution is acceptable.
