Solar Borehole Pumps run directly from solar panels through a controller, pumping water during the day into storage. They suit off-grid farms and smallholdings, and homes that want water through load-shedding without batteries.
- Give the borehole depth, water level and tested yield.
- Say how much water you need per day and where the tank is.
- Say whether you are replacing a mains pump.

Compare Borehole QuotesHow Solar Pumping Works
- Panels produce DC power that a controller feeds to the pump.
- Flow rises and falls with sunlight, so pumping happens mostly in the middle of the day.
- Storage tanks hold the day's water for night and cloudy days.
- Most systems run without batteries. Some hybrid controllers can also run from mains or a generator.
Sizing a Solar System
- Daily volume. Litres needed per day, using winter sun hours.
- Total head. Depth to pumping level plus lift to the tank.
- Yield. The pump must not exceed the borehole's sustainable rate.
- Panels. Enough panel capacity for the pump, with a margin for winter and dust.
- Storage. At least a day's demand, more for livestock.
Equipment Options
| Item | Notes |
|---|---|
| DC solar pump | Efficient, runs directly from panels |
| AC pump with solar inverter or hybrid controller | Can retrofit an existing pump in some cases |
| Panel frame or tracker | Fixed frames are common; anti-theft fixings matter |
| Controller | Dry-run and tank-full cut-off |
Retrofitting a Mains Pump
Some existing AC pumps can be run through a solar pump inverter. Others are better replaced with a DC solar pump. The installer should check the pump's size and condition and the cable run before recommending either.
The Solar Borehole Pumps Process
- Assess. Depth, yield, demand and panel position.
- Design. Pump, controller, panels and storage are matched.
- Install. Panels, frame, controller and pump are fitted.
- Commission. Flow is measured at different sun levels.

Solar Borehole Pumps FAQs
Do solar borehole pumps need batteries?
Usually not. They pump to a tank during the day, and the tank supplies water at night.
Will a solar pump work in winter?
Yes, with less water per day. Systems should be sized for winter sun.
Can I keep my existing pump?
Sometimes, with a solar pump inverter. It depends on the pump and its condition.
Are solar pumps suitable for deep boreholes?
Many are, but deep, high-volume pumping needs more panels and a larger pump.
Will solar save money?
It removes or reduces the pump's electricity use, but savings depend on your tariff, use and system cost. No saving is guaranteed.
