Solar Water Pump Solutions
SUN ENERGY GENERATION PRIVATE LIMITED is Chennai’s fastest-growing Solar EPC (Engineering, Procurement, and Construction) company.
A solar water pumping system powered by solar energy directly converts sunlight into electrical power to draw water from wells, boreholes, rivers, or storage tanks. These standalone systems replace grid dependence and diesel generators for agricultural irrigation, livestock watering, and off-grid residential water supply.
By Motor & Power Drive
BLDC (Brushless DC) Systems: Highly efficient (85–95%) for small-to-medium systems (0.5 HP to 5 HP). Connects to solar panels via a specialized DC pump controller, requiring no inverter.
AC Induction Systems: Driven by Variable Frequency Drives (VFDs) or solar pump inverters that convert DC panel output to 3-phase AC electricity. Preferred for heavy-duty industrial or large agricultural applications (5 HP to 20+ HP).
Direct-Drive vs. Battery-Backed: Most agricultural solar pumps run direct-drive without batteries (storing water in an elevated storage tank instead of storing electricity in chemical batteries).
Key Sizing Factors
When selecting a solar pump system, consider three essential parameters:
Total Dynamic Head (TDH): The vertical distance water must be lifted from the dynamic water level in the well to the discharge tank, plus pipe friction losses.
Daily Water Demand ($Q$): Expressed in liters or gallons per day required for crops, livestock, or household use.
Peak Sun Hours (PSH): Average daily effective solar radiation available at your geographic location (typically 4.5 to 6 hours/day).
