This guide supports solar borehole pumping projects in Kenya. Use it to prepare the information needed for a site-specific discussion and to compare proposed work on a consistent basis.
Turn assumptions into an itemised scope
Include the pump if needed, array, mounting, controller, electrical protection, cabling, installation, tank controls and storage changes.
The information to collect
Use solar energy to pump water into a well-planned storage system. The array, controller and pump must work together at the required head while respecting the tested operating limits of the borehole.
- Pumping-test results and the required total dynamic head
- Daily water demand and usable storage volume
- A shading-free array location with mounting options
- Any grid or generator backup requirement
A practical review process
First, name the intended outcome and the person responsible for approving the design or scope. Gather the existing site records and mark anything that is an estimate. Ask the provider to explain which missing measurements could change the recommended equipment or work.
Next, compare the proposed deliverables with the actual requirement. Keep the quotation, specification and acceptance criteria together. If the design changes after assessment or testing, record what changed and approve the revised scope before proceeding.
Avoid a misleading comparison
Panel wattage alone cannot predict daily water delivery. Pump efficiency, head, solar conditions, shading, controller limits and borehole yield all matter. Water storage can be more appropriate than adding batteries to a pumping-only system.
Include the pump if needed, array, mounting, controller, electrical protection, cabling, installation, tank controls and storage changes.
Check the result at handover
Request the electrical layout, component ratings, controller parameters, measured commissioning conditions, dry-run protection checks and a maintenance schedule.
Adapt the brief to your site and audience
A household may prioritise simple operation and reserve supply. A school or NGO may need operator training, beneficiary or occupancy information and procurement records. A farm needs its irrigation or livestock demand defined. A diaspora-funded project also needs clear local access and remote approval responsibilities.
Continue with solar borehole pumping, county planning guidance and a project enquiry.
Does this guide replace a site assessment?
No. It is a planning checklist. Final engineering, water-use decisions and equipment selection depend on measured conditions and the responsible professionals’ assessment.
What should I send when requesting a quote?
Start with your Kenyan site location, intended use and existing records. For this service, prioritise pumping-test results and the required total dynamic head and daily water demand and usable storage volume.
