Borehole Solar Water Pump Prices in Kenya.
What Are The Borehole Solar Water Pump Prices in Kenya?
The prices of borehole solar water pumps in Kenya can vary depending on several factors such as the borehole depth and yield. Generally, the prices of borehole solar water pumps in Kenya range from KES 38,000 to KES 2,500,000.
For example, a 1″ solar pump with a float switch can cost around KES 22,500. However, it’s worth noting that this price is exclusive of a 3% service charge, which may be added to the final cost.
Another significant factor that influences the price of a borehole solar water pump is the submersible water pump type, which can either be electric or solar-powered. Additionally, the specifications of each model also play a significant role in determining its price.
It’s important to note that the cost of installing a borehole is typically provided separately from the cost of procuring the water pump.
When planning to install a borehole solar water pump, it’s essential to consult with a professional supplier or installer to determine the most appropriate pump model and ensure that the installation is done correctly.
How to Select the Best Borehole Pumps?
When selecting the best borehole pump, there are several factors to consider. Here are some of the key factors to keep in mind:
- Pump head: This is the maximum height that the submersible water pump can push water against gravity. It’s measured in meters and determines the pump’s pressure rating. For example, if a pump has a 90-meter head, it can push fluid vertically up to a maximum of 90 meters.
- Discharge rate or flow rate: This is the amount of water that the pump can move in a given time, usually measured in liters per hour.
It’s important to ensure that the pump’s discharge rate at the borehole’s depth matches the recharge rate recommended in the borehole’s test pumping report. If the pump’s rate is too low, you may receive less water, and if it’s too high, you risk pumping the borehole dry.
- Mode of power: The type of pump you choose, whether it’s a submersible electric, solar, or hybrid pump, will impact the borehole pump price. Solar pumps have a higher initial purchase and installation cost but have near-zero running costs.
Electric pumps are cheaper to buy and install but incur monthly electricity charges. Hybrid pumps combine electric and solar power and are ideal for off-grid locations.
- Motor size: Each submersible water pump has a motor that powers the pump. It’s measured in kilowatts (kW) or horsepower (Hp), and the larger the motor, the bigger the pump, and vice versa. The motor size will impact the specific borehole pump cost.
By considering these factors and working with a reputable supplier or installer, you can select the best borehole pump for your needs and ensure that it’s installed correctly for optimal performance.
Steps to Choosing a Solar Panel to Run a Water Pump.
When selecting a solar panel to run a water pump, follow these steps:
- Multiply the required kW by 1.5 for poly-crystalline solar panels or by 1.25 for mono-crystalline solar panels to account for power losses during transmission.
- Look for solar panels with wattage closest to the calculated value.
- Divide the total required power by the wattage of the selected panel to determine the number of panels needed.
For example, if the required power is 12,000 watts and a 545-watt panel is selected, 22 panels would be needed. For a small pump that needs only 300 watts, a single 300-watt panel would be sufficient.
There are various types of solar water pumps available for boreholes in Kenya, suitable for shallow and deep wells.
Borehole Water Pump FAQs.
I. How Do You Size A Borehole Pump?
The size of the borehole pump is determined by considering the static water level, dynamic head, recharge rate of the borehole, and pumping height.
Ii. Which Is The Best Borehole Water Pump?
The best borehole water pump is one that meets your pressure and water volume needs and has a stainless steel motor instead of a plastic one.
Iii. How Long Can A Borehole Pump Run Continuously?
An ordinary borehole pump should ideally run for 7 to 8 hours a day. Running for prolonged periods frequently can damage the motor and increase your electric bills.
Iv. What Type Of Pump Is Used For Boreholes?
An electric submersible or solar-powered submersible water pump is used for boreholes. They are centrifugal pumps driven by a submersible stainless steel motor, and they must always remain submerged during operation.
V. How Long Should A Borehole Pump Last?
A correctly installed, stainless steel borehole water pump can last for many decades with proper usage and timely servicing.
Vi. How Often Should A Borehole Pump Be Serviced?
It is recommended to have a borehole pump serviced annually or after every 5,000 hours of operation. However, if you notice any changes in the water pressure or flow rate, it is important to have the pump serviced immediately.
Vii. Can A Borehole Pump Be Used To Pump Other Fluids Besides Water?
No, borehole pumps are specifically designed to pump water and should not be used to pump other fluids as this can damage the pump and compromise its functionality.
Viii. Can A Borehole Pump Be Used In A Well That Has Limited Water Supply?
It is not recommended to use a borehole pump in a well that has a limited water supply as this can cause the pump to overwork and potentially damage it. It is important to ensure that the well has sufficient water supply before installing a borehole pump.
Ix. What Is The Warranty Period For Borehole Pumps?
The warranty period for borehole pumps varies depending on the manufacturer and the model of the pump. Typically, warranties range from 1 year to 5 years. It is important to check the warranty details before purchasing a borehole pump.
X. Can A Borehole Pump Be Installed By The User Or Should A Professional Be Hired?
Borehole pumps require professional installation to ensure that they are properly installed and function correctly. It is not recommended for users to install borehole pumps themselves, as this can result in improper installation and potentially damage the pump.
