Solar pump demand in Africa is driven by farmers and projects that lack grid power, face costly diesel supply or want to cut running costs. Pumps for solar irrigation need a matched pump, controller and array, and the buyers who succeed specify the whole system, not only the pump.
We do not quote market sizes here. Published figures vary by source and change often, so check a recent report from a development agency or industry body before using any number in a business plan.
What drives demand?
Three factors recur. First, many farms are far from the grid, and extending it is slow. Second, diesel must be trucked in, and its supply and cost swing. Third, solar panels have become widely available, and a solar pump has no fuel to buy once installed.
Programmes by governments, NGOs and development banks also support irrigation, which creates tenders for pumps. These often have written technical requirements, covered in our guide to machinery for NGO and government tenders.
What does a solar pump system include?
A complete system has more than a pump. Buyers should ask for each item to be named in the quotation:
- The pump and motor, either submersible or surface, matched to the head and flow.
- A controller, often a solar pump drive that tracks the panel's maximum power point.
- The solar array, sized to the pump's power and the sun at your site.
- Cables, mounting structures, protection devices and a dry-run or float switch.
- A storage tank where the farm needs water outside sunny hours.
What should a buyer check?
Pump output depends on the sun, so ask the supplier for a performance table showing flow at different heads and different panel power. Read this with the pump curve rather than relying on a single rated figure.
Look at the motor type. Some systems use DC motors, others use AC motors with a drive. Ask how each is protected from dry running, over-voltage and lightning, and how easily the controller can be repaired. Our note on VFDs with pumps explains the role of the drive.
Also check how the pump copes with sand and with a changing water level, since both are common on African boreholes.
Ask for a test report for the exact model, with flow measured at several heads. A catalogue curve for a related model is not proof that your pump will deliver the water your crop needs.
What about supply and service?
A system that stops after one season is worse than none. Ask for a stock of controllers and a set of pump spares, a manual in your working language and a clear warranty with a process for claims. Train a local installer, or have the supplier do it, because poor installation causes many early failures.
Panels are often supplied by a different maker than the pump. Decide who is responsible for the complete system, and name that party in the contract. See solar pumps made in Gujarat for what Indian makers offer.
