Role of solar energy in agriculture




Role of solar energy in agriculture:

1) Solar Powered Pumps:


              A switch from conventional diesel  and electric-powered irrigation pumps to solar-powered, one can help the country achieve 38 per cent of its envisaged 175 GW renewable energy target by 2022.

            Farmer to pay only 10% cost of solar pumps under KUSUM Budget scheme

            The Indian farmer will effectively bear only 10 per cent of cost for solarising his agricultural pump under a scheme unveiled in the Budget 2018-19.

              The government will spend Rs 48,000 crore over 10 years as central financial assistance (CFA) on the KUSUM scheme which aims to encourage the use of barren land for setting up solar power plants.

               Government is  proposing to solarise every agricultural pump and they will be connecting all the grid connected pumps with solar power


2) Solar Fencing in Agriculture:

               It plays a vital role in farming, from being attacked by domestic and wild animals. In Karnataka they are giving 50% subsidy for farmers. 
              
           Solar fencing is an alternative to conventional methods of fencing to protect your crops & property. Electric Fence is an effective way to reducing losses caused by animals.                                  

                                                                                                    
  
a). How is works:

                 When an animal or human being comes into contact with the electric Fence, they receive a sharp, short, painful but safe electric shock. The shock does not cause any physical damage. The electric fence acts as a strong psychological barrier as any intruder avoid coming into contact with the electric Fence once they experience the shock. After a period of conditioning, the mere presence of the fence acts as an effective barrier even if it is not powered 'ON'.
Electric fence can be made to detect a fault on the fence like shorting or cutting of the wire due to tampering on the fence with the Alarm system. 


b). Special Features of the Solar Electric Fence System:

    Electric Fence can be built alongside existing fences except in case of barbed wire fences.
  •  Existing posts can be made use of provided the corner / end poles are strong.
  • The shock does not physically harm animals or human beings.
  • The Solar Electric Fence System conforms to National and international Standards.
  • The Solar Energizers are tested by ETDC, Govt. of India.
c). Advantages over conventional fences:

The major advantages of Electric Fences over traditional fences are:
  • Fence posts are erected 6 - 8 mts apart depending upon the terrain.
  • No barbed wires are used. Only plain High tensile (Strong) wire is used.
  • A long life as the fence is not subjected to physical pressures of wear and tear.
  • Selective barriers possible. For example, Elephant barriers can be designed to allow smaller animals like cattle to move in and or out.
  • It is used in more than 165 countries all over the world.
  • It is the most effective method of fencing, and is safe to all kinds of animals and to human beings.
  • It is easily constructed and maintained.
  • It is long lasting and can be modified, extended, shifted and re-erected from one place to another, without loss of materials and waste of labour.
  • This is the only method of fencing, which can effectively keep all kinds of wild animals out.
  • It is not dependent on regular electricity supply as it operates on battery.
    d). Maintainance of Electric Fence:
    Solar Electric Fence system requires very little maintenance. The following tips help you in proper maintenance of the fence:
    • Ensure that your solar electric fence is a complete electric fence system with all the correct accessories.
    • Make sure that the Energizer I Control unit is protected from rain and housed inside a secured area.
    • Clean the top surface of the solar panel regularly to remove accumulated dust if any.
    • Ensure that the solar panel mounting is proper in the North – South direction at an angle of 15 degree.
    • During heavy storm and lightning, disconnect the energizer from the fence. This will prevent severe damages to the energizer.
    • Earthing is very important for good performance. Use good number of Super   Earth Kits. Do not install the earth kit near mains earthling.
    • Check for vegetation growths regularly. Keep the fence line clean.

    e). Battery Maintenance:

    • Ensure that the terminals are clean. Use petroleum jelly periodically.
    • The specific gravity of the battery should be maintained between 1150 - 1250.
    • Add distilled water to maintain the level of electrolyte in each cell of the battery.
    • Keep the battery in an upright position on a wooden plank.
    • Never add acid to the battery.
    • Ensure that the initial charging of the battery is done properly. Do not keep the battery unused for more than one month.

Net Metering

   Net Metering    is   a   new   concept   where   an instrument  which  has  a  special  metering  and billing  agreement  between  utilities  and  their customers,  facilitates  the  connection  of  small,renewable energy-generating systems to the power grid. This new  programme  is  being  developed  to  encourage  small-scale  renewable  energy  systems  to  ensure  that  customers always  have  a  reliable  source  of  energy  even  when  their renewable  generators  are  not  producing  energy,  and  to provide substantial benefits to the electric power-generating system as well as the environment. When  a  net  metering  client’s  renewable  generator  is producing more power than is being consumed, the electric meter runs backward generating credits. Whenever the net metering customer uses more power than is being produced, the meter runs forward normally. Net metering customers are charged only for the net power that they consume from the electricity service provider t

Solar Rotation Hanger

Image
In cities, usually we will be little worried about drying clothes in our balcony. During winter and rainy, we try a lot to dry our clothes, turning them, changing to sunlight, fading out colour, if receives too much sunlight. Here we got a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health. An Innovation different way from traditional clothes drying method. It is a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health.   The hanger rack can rotate 360 ° to sunlight the laundry in all directions. Derived by rigorous calculation, It can reach 6 rotations per minute moderate rotation speed. Th
