Solar Water Pumps For Agriculture

Grekkon Limited’s solar water pumps for agriculture have different specifications in pressure rating (head), flow rate, and the motor size (Megawatts). Our solar water pumps for irrigation in Kenya range from small portable to large immobile units. The choice of a farmer’s solar water pump is a factor of acreage because, the area under irrigation determines the water use Our solar water pumps prices are tailored to the well’s depth, yield and head. These solar pump’s costs range from as low as Kes 37,000 to over Kes 1,500,000. For instance, a farmer with a 6M shallow well yielding 0.5 cubic litres an hour will work with a basic solar water pump. Another grower with a deep well of 280M, and a yield of 15 cubic litres per hour will have a large pump installed  

 

Types Of Solar Water Pumps For Agriculture

1. Submersible water pumps

These are the most common ones with farmers installing them in deep or shallow wells. They are also done in rivers and pools. They work when fully immersed in water. Stainless steel submersible solar water pumps are common in every well. There is a more efficient and affordable plastic version. This is for rivers, pools, and water tanks. It works with the same principle as the stainless steel one

Submersible solar water pumps for agriculture prices

Our solar water pumps prices range from as low as Kes 38,000 for small portable units, to over Kes 2,000,000 for large types. The former have a low head, and low water flow rate. The latter is for very deep wells and with lots of water  

 

To recommend and price your right submersible solar water pump, a test pumping report is required. It will show; the well depth, the dynamic head, the static water level, and the pump placement level is necessary. Where such is lacking, then a float switch attached to the water pump is necessary. It ensures that it only works when submerged in water. The motor is damaged when the water pump runs ‘dry’  

2. Surface solar water pumps

These solar surface water pumps work without any external contact with water unlike their submersible type counterparts. They are easily portable unless it’s too large to move about.  

 

3. Direct current (DC) water pumps

These are purely solar water pumps that work under a DC current. They will not require an inverter, unless a farmer chooses to install one. This is to modify it to use an alternating current (AC)  

4. Alternating current water pumps

These are purely electric water pumps that work under an AC current. To convert it to a solar water pump, an inverter converts the DC to AC. The DC is from the solar panels

Solar-powered water pumps FAQs

X. What are the disadvantages of solar water pumping?

• The initial set up cost is expensive
• If placed in an insecure location, the risk of theft is high
• It does not pump at night or when it gets very cloudy

XI. Can I connect a pump directly to a solar panel?

No you cannot because all connections origination from the panel or the pump has to go through the control unit

Water Pumps In Kenya

Water pumps in Kenya by Grekkon Limited are varied for different purposes. This provides a wide choice to select from for growers according to irrigation use. Below are water pumps by Grekkon Limited

Water pumps in Kenya

Categorisation

1. By displacement

1.1. Centrifugal pumps work through centrifugal force to drive water that enters the impeller. They use the rotational energy from the spinning impeller to produce hydrodynamic energy

1.2. Positive displacement water pumps use a piston, a diaphragm, or a rotating cog or gear to mechanically move a fixed volume of water through the pump chamber

 

 

2. By Location

2.1. Surface pumps suck water through an inlet pipe, then pump it out from an outlet pipe. They are set horizontally on dry surface. Theses are; electric surface pumps including booster pumps, solar surface pumps, diesel and petrol generator water pumps

 

 

2.2. Submersible water pumps work under water in wells. The size and power depends on the well depth, and discharge rate. They are either solar or electric powered

3. By power output

3.1. Electric motor powered pumps are either electric (AC current), or solar (DC current) water pumps

 

 

3.2. Generator powered water pumps are either diesel or petrol types. These are available as high pressure, high volume, low pressure and low volume

What To Consider When Buying Your Water Pump

1. The head/ pressure rating

This is the vertical pumping distance in meters or bars. The higher it is, the higher the pressure needed, and the more powerful is the engine or motor. Fuel engine (generator) or electric motor power is horse power (Hp), or in Kilowatts (kW) for the latter

2. The flow rate

This is the amount of water pumped evacuated per unit time. It is in litres per minute or per hour. The higher it is, the larger the water pump inlet and outlet size

For agricultural use, PVC or HDPE water pipes are connected to these pumps. The pipes evacuate water to the crops

3. The power rating

The motor or engine size provided in kilowatts (kW) for the former, and in horse power (Hp) for the latter determines the water pump’s efficiency. The larger the flow rate and the discharge, so will the engine or motor be

Solar Water Pump Prices

Solar water pump prices in Kenya by Grekkon Limited are provided based on the pump specs. Our submersible solar water pumps for sale in Kenya are categorised as;

1. Motor size. This is given in kilo watts (kW) or horse power (Hp). The motor operates on direct current (DC) generated by the solar panels, or from a battery. The larger the motor size, the more the power a motor consumes, and provides to the pump
2. Head. This is the pressure rating provided in meters (M) or bar. It determines how far vertically that pump will push water. The higher the pressure rating, the higher the push. Deep wells use higher pressure rated submersible solar pumps than shallow wells
3. Flow rate. It is the volume of water evacuated over a given time unit. This is given as litres per second, or per minute, or as cubic litres per hour. This determines the size of the outlet pipe. A pump that evacuates more water has a larger outlet

Smaller domestic water pumps are portable solar water pumps. It is easy to move them from one shallow well to another. This is not the case for large, permanent, deep well solar water pumps
