Solar Powered Auto Irrigation System

• Introduction
• Solar energy is the most abundant source of
  energy in the World. Solar Power is not only an
  answer to todays energy crisis but also an
  environmental friendly form of energy.
• Photovoltaic generation is an efficient approach
  for using the solar energy. Solar powered
  irrigation system can be a suitable alternative
  for farmers in the present state of energy crisis
  automatic irrigation system using solar power
  which drives water pumps to pump water from bore
  well to a tank and the outlet valve of tank is
  automatically regulated using controller and
  moisture sensor to control the flow rate of water
  from the tank to the irrigation field which
  optimizes the use of water.

• Automatic Solar Submersible Pump Control For
  Irrigation
•  
• These systems work in the sunlight. When sun
  shines the water pumping process is a sensible
  way of solar electric power utilization
  throughout the summer, as the water necessity is
  the highest. These pumps provide a reliable water
  source for plantation.
• For any solar based pumping system, the capacity
  to drive water is a function of three variable
  such as power, flow and pressure.

• Solar Panel
• These panels are designed with solar cells
  composed of semiconductor materials.
• The main function of Solar panels is to convert
  solar energy into DC electrical energy generally
  of 12V, which is further used for the rest of the
  circuit. The number of cells required and their
  size depends on the rating of the load.
• The collection of solar cells can produce maximum
  electricity. But, the solar panel must place
  exactly at right angles to the sun rays.

• The Source
•  
• Water sources are available in the form of
  springs, drilled wells, rivers, ponds, etc.

• Submersible Pump
• This solar system contains a submersible pump, a
  water tank, an irrigation pump, associated water
  pumps.
• This system is designed with 450W of power, which
  is capable of pumping 2000 liters of water within
  60 minutes.
• This power capacity takes into account the height
  difference between the water tank and the solar
  submersible pump.

• Charge Controller
•  
• A solar charge controller is very important
  device in any solar-power system.
• It is used to maintain proper charging voltages
  of the batteries.
• The charge controller controls current and
  voltage from the solar panel and charges the
  battery, and also stops the charging of the
  battery from over and undercharging conditions.

• Battery
• The Battery is an electric device that is used to
  store current which is produced from the solar
  panel and supplied to the corresponding loads.
  The number of batteries required depends on the
  load requirement.

• Inverter
•  
• The main function of the inverter is that it
  converts the batterys voltage to AC voltage in
  order to activate then loads. Therefore, it helps
  us to run many electronic devices, home
  appliances and computers.
• There are numerous types of inverters available
  in the market today.
• The characteristics of typical inverters include
  high switching frequency, high conversion
  frequency and less harmonic content, and so on.

• Applications
• Agriculture livestock watering / crop irrigation,
  home gardens and drip irrigation systems.
• Domestic portable water for remote homes,
  campgrounds.
• Pond water management and water transfer.
• Water supply for villages in developing world.
• equivalent voltage this is given to a sensing
  circuit which has a reference voltage that can be
  adjusted by the farmer for setting different
  moisture levels for different crops.

• Conclusion
• By using the automatic irrigation system it
  optimizes the usage of water by reducing wastage
  and reduce the human intervention for farmers
• The excess energy produced using solar panels can
  also be given to the grid with small
  modifications in the system circuit which can be
  a source of the revenue of the farmer, thus
  encouraging farming in India and same time giving
  a solution for energy crisis.
• Solar pumps also offer clean solutions with no
  danger of borehole contamination.
• Solar Powered Auto Irrigation System is very
  helpful to Engineering Students.
