Overview

A solar pumping procurement workflow that starts with water demand, lift, borehole or surface-water conditions, and irrigation timing. It coordinates PV modules, mounting, electrical protection, and a project-matched pump controller or drive. Pump model selection and hydraulic design must be confirmed with the local pump specialist and installer.

Solar Water Pumping + Agriculture equipment configuration

Common Challenges

Farmers need water at the right time, but fuel delivery, grid availability, and battery cost can make conventional approaches difficult.
A pump cannot be selected responsibly without head, flow, source conditions, and pipe information.
Field equipment must be maintainable and protected from dry-run, low-water, and weather exposure.

Our Approach

Treat water storage as the primary buffer where the irrigation schedule permits, rather than adding batteries by default.

Collect the pump curve and site data before matching PV array, controller, protection, cable, and mounting scope.

Separate the supply package from hydraulic installation and borehole assessment responsibilities.

Key Benefits

Water-first sizing
The system starts with required flow and lift, avoiding an arbitrary PV size.
Avoid unnecessary storage
For daytime irrigation, a water tank can often be the appropriate energy buffer.
Field-serviceable scope
Documentation and spare recommendations can be organized for routine local maintenance.

Typical Configuration

PV array
Modules and ground structure sized for the selected pump drive and local solar resource assessment.
Solar pump controller / drive
Project-matched controller with required protection features, confirmed against the final pump.
Pump and hydraulic package
Pump model, pipework, and water storage selected by the responsible pump specialist using site data.
Field protection and cabling
DC isolators, surge protection, cable, enclosures, and labels suitable for the installation environment.

What we need for a useful RFQ

Water requirement
State daily water volume, required flow, irrigation schedule, and storage capacity.
Hydraulic site data
Share water source, total dynamic head, borehole or surface-water details, pipe length, and pipe diameter.
Site conditions
Confirm roof or ground area, electrical supply, installation environment, and available equipment space.
Destination requirements
Provide destination country, grid code or permit requirements where known, requested documents, and delivery target.

Where this package fits

Malawi
Smallholder irrigation and productive-use systems fit markets where off-grid access and agricultural livelihoods are both important.
Nigeria
Farms and rural enterprises can use solar pumping to reduce dependence on fuel logistics.
Philippines
Agricultural sites need pump and weather conditions evaluated locally before equipment selection.

Procurement and delivery notes

An RFQ needs flow rate, total dynamic head, water source, pipe route, irrigation schedule, and pump preference if known.
Pump, hydraulic, civil, and borehole works must be verified by the responsible local specialists.
