Solar Powered Water Pumps
What is a Solar Powered Water Pump
A Solar water pump is an electrical pump in which electricity is generated by Solar PV systems. Solar water pumps are environmentally friendly because they are powered by the sun.
Application
Solar Water Pumps meet a broad range of needs including crop irrigation, livestock watering, and domestic use.
Types of Solar Water Pumps
There are two types of Solar Water pumps namely the Submersible water pumps and Surface water pumps
Submersible Solar/DC Pumps
Lift to 650 feet and fit in a 4″ or larger well casing. Submersible solar pumps are used when the water supply is more than 20 feet from the surface. They can operate directly off solar panels, batteries, or in some cases an AC power source.
Surface Solar/DC Pumps
Good for applications with shallow wells, ponds, streams, or storage tanks. Best if the water supply is 20 feet or less from the surface. Used primarily for solar water heating applications. These solar pumps run directly from a small solar panel. No battery is required.
Sizing and designing a Solar Water Pumping System
This depends on many factors including;
- How much water do you need
- When you need the water
- Is your water source a stream, pond spring, or well?
- Water available in gallons per minute
- Depth of the well
- How far the water needs to be pumped and with what elevation gain
- Water quality problems like silt or high mineral content that may damage the pump
- How much volume is available in storage tanks and how the tanks are arranged
Advantages of Solar Water Pumps
- Solar water pumps are environmentally friendly since they are powered by the sun
- Because they are powered by the sun, they work perfectly in remote areas where there’s no access to the national grid
- You don’t need to pay a ton of money each time you use your solar water pump. There are no cumulative electricity bills since the system is powered by the sun
- Solar water pumps as easier to maintain compared to conventional pumps.
- Solar water pumps work efficiently while saving you a ton of money.
Which Type of Solar Water Pump is suitable for me?
The type of solar water pumping system you need will depend on the water source. If the source is a borehole (proposed or existing) or deep well, then a submersible pump that fits the borehole or well will be suitable. If the water source is a river, then a surface pump is recommended. If the water resource is a shallow well, pond, or lake, then either a surface or floating pump may be selected.
