Selecting the correct solar pump is essential for efficient irrigation and long-term satisfaction. This guide walks you through the key factors to consider when choosing a solar pump system.

Assess Your Water Source

The type of water source determines the pump category:

Surface Sources (Rivers, Lakes, Ponds)

• Use surface pumps
• Consider suction lift limits (typically 7 meters maximum)
• Account for seasonal water level changes

Wells and Boreholes

• Use submersible pumps
• Know your well depth and water level
• Consider well diameter for pump fit

Calculate Your Water Needs

Determine daily water requirements:

• Crop needs: 20-50 liters per square meter per week depending on crop
• Livestock: 30-50 liters per animal per day for cattle
• Household: Additional needs for domestic use

Understand Total Dynamic Head (TDH)

TDH is the total height water must be lifted plus friction losses:

• Vertical lift from water source to discharge point
• Pressure required at discharge
• Friction losses in pipes (typically 10-20% added)

Match Pump to Solar Panels

Solar array sizing depends on:

• Pump power requirements
• Daily operating hours needed
• Local solar insolation (average sun hours)
• Seasonal variations in sunlight
