Many farmers in Kenya pump water by using petrol pumps, hand or carry it in buckets from a village water collection point to their crops. Not only is this a slow and physically grueling task, but often times the shallow wells and seasonal rains mean farmers can’t grow crops in the dry season. If you are starting out in farming the costs incurred of running petrol pumps can make you give up almost immediately if you combine this challenge with other beginner setbacks that affect new farmers.
Farmers need a reliable, low-cost water pumping system to grow the extra food they need to make a poverty-busting profit.
Such a pump is the GF1 Submersible Solar Pump designed to be the perfect water pump solution.
The GF1 Submersible Solar Pump
GF1 Submersible Solar Pump is a 12v/24v DC pump which helps solve your remote farm pumping requirements. The pump has a lift of 100m and can pump 720 liters per hour under continuous flow. It is rugged, durable and long service life.
Its unique waterproof power connector can prevent water wicking and prevent potential condensation problems.
Complete Package: KES 48,000
- 100m PE pipe with fittings
- Battery + Charge Controller (Lasts for 12 hours when fully charged)
- 120 watt Solar Panel
- 50m Electrical Cable
NB: The solar pump is “direct current” which means you can use the pump directly with the solar panels without the battery and it starts working. The battery is only included when you need to pump at night or when there is no sunlight.
Minimal Package: KES 35,000
- 120 watt Solar Panel
- 100m PE pipe with fittings
- 10m Electrical Cable
- Suitable for well or larger-sized wells
- Anti-corrosion housing, stainless steel fasteners
- Can run dry for a short time when there is no water in the well.
- Pump power is 120 watt can also can use battery or charge controller to run

Frequently Asked Questions
What is a solar photovoltaic (SPV) water pump?
A solar PV Water Pump consists of a Photovoltaic array mounted on a stand, and motor pump set compatible with the photovoltaic array: As the sun’s rays falls on the solar module D.C electricity is generated and is used to run a D.C motor pump set or an A.C motor pump set. AC motor requires an inverter.
How does a solar water pump work?
As mentioned earlier, it works like any other pump set with the only difference being the solar energy used instead of nonrenewable energy for its operation. When sunlight falls on the solar panels it produces direct current (DC) which then feeds the motor to pump out the water.
What is the use of solar water pumps?
A solar water pump is used for extracting water from ponds, rivers, bore-wells or other sources of water which are then used to meet the water requirements for irrigation, community water supply, livestock and other purposes.
What are the advantages of solar pumps?
Solar pumps operate on solar energy available free with nature, and thus save expenditure on diesel or electricity.
- The cost of operation and maintenance of solar pumps is negligible
- Useful for water pumping in remote areas without grid power.
Are there any criteria for selecting where to install the solar water pump sets?
Yes, there are certain criteria for selecting the location for both the solar panels and the pump. In the case of the solar panels, they should be installed in an area which is shade free and has no dust or dirt, has a low incidence of bird droppings and which can provide space for unrestricted tracking movement (keeping the orientation of the solar panels in the direction of maximum solar irradiation). Also, the surface where the panels are mounted should be even. Panels should be easily accessible for cleaning and should be as close as possible to the pump and water source.
Does a solar water pump work during cloudy and foggy days?
No. Lack of sunlight affects the working of solar water pumps. On such days, you could add a battery and solar charge controller to act as a backup system.
Can hail storm lead to the damage of the panels? What precautions should be taken during storms to save the panels?
The modern day solar panels have adequate safety features and are very unlikely to be damaged by a hail storm.
What maintenance is required for a solar powered pump? Does the performance of the solar water pumps get affected over the years of use?
The system needs very minimal maintenance which includes cleaning of the panels on a regular basis. Cleaning maintains the efficiency of the panel without which the panel’s surface gets reduced exposure to irradiation from the dust and dirt on it.
In comparison to diesel pumps, solar water pumps have a significantly longer life expectancy and continue to produce electricity for even longer than 25 years.
Can I “pull” water out of a Well, River, Dam, Pond?
Yes, you can.
