Solar-Powered Water Pumping Solutions
(PV) Photovoltaic Solar - Simplest, Affordable & Cost-effective Systems

Working Principle of Solar Water Pump

A solar pump works on the base of the photovoltaic principle. During the working of a solar pump, PV (photovoltaic) systems absorb radiant solar energy and transform it into electricity. This produced electricity supplies to the entire system.

The inverter of the pump converts the direct current output of the PV system into alternating current, which drives the pump. These inverters also adjust the output frequency and voltage in real-time, corresponding to variations in the sunlight intensity to attains the highest power point tracking.

Severe shortages of both energy and water create a challenging environment for farmers in Lebanon, posing a threat to the country’s food security.

Irrigation systems that run on solar power are increasingly being recognized as an effective solution for Lebanese farmers, a reliable and clean energy supply to power highly efficient irrigation techniques. The system is also affordable, with upfront costs between $4,000-11,000, and minimal operating costs.

Irrigation with solar pumps is a new method, which requires neither electricity nor any fuel. It consists of a motor that draws water from the ground and has solar panels to run it, which generate energy from the sun's rays and run the machine from it.

Micro-Irrigation in Lebanon

Lebanon is facing a harsh water crisis, lack of proper government planning, industrial and human waste. The agriculture industry is also the major cause of the crisis. Outdated irrigation techniques used in the country led to wastage of water.

Micro-irrigation is the modern method of irrigation which helps to save water and increases the water use efficiency. It makes use of drippers, sprinklers and foggers. Micro-irrigation can increase yields and decrease water, fertilizers and labor requirements. It can also help to bring the degraded, uncultivable land under cultivation.

Advantages of Micro-Irrigation

• Will help farmers to achieve better results.

• provides a clear solution that not only drastically curbs water usage

• delivers other benefits to farmers like improved yields, cost savings, and higher profits.

• A process of slow water application via discrete or continuous drips, tiny streams, or miniature sprays on.

• Above, or below the soil by surface drip, subsurface drip, bubbler, or micro-sprinkler systems.

• This technique proved successful been in developed countries like India, Pakistan and other Fareast countries in turning around their national water crisis.

Techniques of Micro-irrigation System

Basic components include a pump and power unit, a backflow prevention device if chemicals are used with water, a filter, a water distribution system, and some devices for controlling the volume of water and pressure in the system. If the water source is from a city/municipal/rural water supply, a direct connection is possible.
