Borehole solar water pump cost in Kenya
Our borehole solar water pump prices in Kenya range from Kes 38,000, to Kes Kes 2,500,000 depending on the borehole depth and yield. This borehole pump price also a factor of the submersible water pump type; electric or solar, and the specifications of each model. The cost of installing a borehole is provided when procuring the water pump.

How to select the best borehole pumps
1. Pump head
This is the maximum height the submersible water pump will push water against gravity. It is in meters, and defines the water pump's pressure rating. For instance if the pump reads 90M head, then it will push fluid vertically to a maximum of 90M
The distance from the highest point of the water pipe to the depth of the water pump is the head
2. Discharge rate or flow rate
This is the amount of water that the water pump will do per given time- usually given in hours. This will be to the borehole's test pumping report recommendation which provides the recharge rate of the borehole. If the water pump's discharge rate at that depth is lower than the test pumping report recommendation, then the user receives less water. If the water pump's rate is higher, then they run the risk of pumping the borehole dry
3. Mode of power
The borehole pump price for a submersible electric, a solar water pump or a hybrid of both is different. Solar water pumps have a high initial purchase and installation cost, and near zero running costs. This is because of support accessories such as the solar panels, the solar panels support structure, and the inverter. They are great in off-grid electricity locations. Electric submersible pumps are cheaper to buy and install, but incur monthly electricity charges. There are hybrid submersible water pumps from manufacturers. An inverter will convert an electric or solar water pump to a hybrid water pump. Electric submersible borehole water pumps have either a single or three phase motor according to the pump size
This is to allow switching to either mode. A hybrid water pump will use solar power on a sunny day, and electricity when the sun is absent. They will be in on-grid electricity locations. Your choice of water pump will there for depend on your budget, and location; is it an on or off-grid electricity area?
Both the electric and solar submersible water pumps have the same lifespan, which is in decades. Borehole solar water pump prices in Kenya depend on the
4. Motor size
Each submersible water pump has a motor which powers the water pump. in kilowatts (kW) or horsepower (Hp). The larger it is, the bigger the pump and vice versa which determines the specific borehole water pump cost
Steps to choosing a solar panel to run a water pump
Understand the motor power rating in kW or Hp
Multiply the kW by a factor 1.5 for poly-crystalline solar panels, and by 1.25 for mono-crystalline solar panels. This is to cater for power losses during transmission
Check the solar panels that have the closest watts per panel. For example if the total required power is 12,000 watts, then divide this by a 545 watts panel. This gives 22 solar panels. If it is a small pump powered by 300 watts, then 1 panel of 300 watts is sufficient
We have various types of solar water pumps for boreholes; from shallow to deep wells. These borehole solar water pumps in Kenya are available in our offices countrywide
Borehole Solar Water Pump FAQs
I. How do you size a borehole pump?
Your borehole test pumping results provide you with the static water level, the dynamic head, and the recharge rate of the borehole. When we factor in your pumping height, then we arrive at the right sized borehole water pump
II. Which is the best borehole solar water pump?
One that meets your pressure and water volume needs, and runs on a stainless steel, not plastic motor
III. How long can a borehole pump run continuously?
An ordinary borehole should ideally run for 7 to 8 hours in a day. Running for pro-longed periods frequently will damage the motor, and if you're using electricity, your electric bills will soar
IV. What type of pump is used for boreholes?
An electric submersible or solar powered submersible water pump. They are centrifugal pumps driven by a submersible stainless steel motor. The water pumps must always remain submerged during operation
V. How long should a borehole pump last?
Our correctly installed, stainless steel borehole water pumps last for many decades in use with timely servicing, and proper usage
