HOW SOLAR PUMPING MACHINE IMPROVE IRRIGATION OPTIONS FOR FARMERS

Agriculture in developing nations isn’t as efficient as it really should be. One of the main problems of agriculture is water management. Even developing nations which receive a good amount of water through rainfall fail to be efficient in the field of agriculture.

The initial investment of solar energy is high. Buts lets put it in a developing nation’s agriculturists/farmers perspective.Rain-fed agriculture can be a high-risk venture, particularly with changing rainfall patterns and high-value crops such as fruits and vegetables. Irrigated cropland is twice as productive as rain-fed agriculture (World Development Report 2008), but many farmers do not have access to irrigation infrastructure, including a nearby water source and power to move the water to and through their fields. Combining drip irrigation kits, newly affordable photovoltaic panels and off-the-shelf, 12-volt pumps can result in a cost-effective system for supplying water for irrigation. Solar-powered irrigation has the potential to increase incomes dramatically, particularly for the most remote producers.Solar water pumps can replace the current pump systems and result in both socio-economic benefits as well as climate related benefits. The water supplied by the solar water pump can be used to irrigate crops, water livestock or provide potable drinking water

BENEFITS OF USING SOLAR PUMING MACHINE FOR IRRIGATION

  • Cost effective, environment-friendly

Another important aspect of solar water pumps usage is that the irrigation water is accessible at a reasonable cost to poor and marginal farmers who have to buy water from water sellers at prohibitive prices. Irrigation is a major input cost in agriculture amounting to about 70 percent of the total cost. The use of solar-powered pumps can decrease the input cost to 25 percent. For a small and marginal farmer, this is considerable and can be a game changer in making small and marginal farming more remunerative. Solar pumps are an attractive alternative technology for irrigation, which serves as a cost effective mode of irrigation with low maintenance requirements.

In addition, solar water pumps operate with zero carbon footprint. The environmental impact caused by the use of diesel pump is often not known to people producers

  • Solar irrigation can increase incomes dramatically, particularly for remote producers with inconsistent access to electricity or fuel.
  • Pump irrigation reduces labor for water delivery.
  • By targeting water at a crop’s roots, drip irrigation can reduce weed and disease pressures, and increase efficiency of chemical applications.
  • Drip irrigation significantly increases water use efficiency

HOW THE SOLAR PUMP SYSTEM WORKS

A 50-watt photovoltaic solar panel can power a 12-volt pump, which can move 1,300–2,600 liters per hour (or 350– 700 gallons). Standard plastic fittings and half-inch piping connect these elements to a water saving tank of 500–1,000 liters. A sturdy stand should be built for the water tank to provide gravity flow, and a frame should also be constructed to provide the best angle for the solar panels. Multiple filters are needed to protect the life of the pump and minimize clogging in sprinkler emitters and tubes. A solar pump combined with affordable drip irrigation kits can be used with a wide variety of high-value crops to increase water efficiency, minimize fertilizer loss, and irrigate hilly terrains.
