Solar water pump sizing calculator.
Screen pump power and solar array from daily water requirement and total head.
Solar water pump sizing inputs
Planning calculation only. Confirm water source, pump curve, elevation, filters, pipe material, emitter uniformity, solar resource, electrical protection and local water rules with a qualified irrigation professional.
Method: The calculator applies entered dimensions, flows and efficiencies as a transparent farm-planning estimate.
Inputs used: Daily water requirement = 50,000 L/day; Total dynamic head = 30 m; Daily pumping time = 6 hours; Pump efficiency = 0.5; Solar-system efficiency = 0.75
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: Planning calculation only. Confirm water source, pump curve, elevation, filters, pipe material, emitter uniformity, solar resource, electrical protection and local water rules with a qualified irrigation professional. Rounding and excluded real-world terms can make an external result differ.
How this solar water pump sizing calculator works
The calculator applies entered dimensions, flows and efficiencies as a transparent farm-planning estimate.
A worked example
Use measured site values to explore a realistic irrigation or harvesting scenario.
Is this a final hydraulic design?
No. Site elevations, equipment curves, pipe data, water quality and local rules require qualified design.
Calculations run on your device. Review your results before exporting or sharing them.
Include the full dynamic head
Lift, pipe friction and delivery pressure affect pump power beyond static depth.
Select final pump and array from manufacturer curves and site data.
