3. INTRODUCTION The supply of electricity is not reached up to some villages Solar and wind energy is most abundant sources of energy in the world. This type of irrigation system is suitable for farmers in the present state of energy crisis in India. Provides free energy after an initial investment is made. It is an eco-friendly and green way for energy production. First goal is to satisfy agriculture needs during irrigation season (spring and summer) and the second goal is to sell back excess electricity to the utility. 3

4. OBJECTIVES Independence against the difficult weather conditions that induce anxiety in the population. Establishment of a competitive and diversified agriculture because of the weight of this sector in the national economy. Independence against the increasing price of oil and gas. Protect our environment from pollution cause by burning oil and gas. 4

5. LITERATURE REVIEW Ajith kumar singh ,” developing hybrid wind and solar powered irrigation system, Harcourt butler technological institute” April 2016 The projection for irrigation water demand basically depends on irrigated area, cropping pattern, effective rainfall, water quality and availability of energy. Providing adequate and quality power to farmers for irrigation purpose remains one of the major challenges before the country due to their remote location hinders any access to a grid . Leon lylesand Edward l skidmore , “ application of wind and solar energy to great plainsirrigation pumping,US department of agriculture” January 1980 Here he investigated application of dedicated wind energy systems without energy storage for irrigation in the Great Plains. Major uses of irrigation energy were identified as pumping for surface distribution systems, which could be supplied by variable flow, and pumping for sprinkler systems using constant flow. 5

7. Working process The fact that DC power is used in solar water pumps as opposed to AC powered devices gives the advantage of the solar pumps being able to function under circumstances of imperfect sunlight conditions. AC power on the other hand needs relatively unchanging voltage as well as frequency to run smoothly. This DC use in solar water pumps allows the device to operate on varying voltage and current. 7

9. PREDICTION OF REQUIREMENT Suppose we have to run 2HP motor for irrigation. For that the energy required is: 2HP=1.5 Kw 1.5 Kw=1500 watt power=volt*current V=240 v so, current(I)=1500/240 =6.25A Requirement for rechargeable batteries of 120v: power=volt*current 1500=N*volt*current(N=number of require batteries ) 1500=N*240*6.25 N=2 (2 batteries required ) 9

10. Requirement for solar panels : 1 solar panel of 72 cells generates 200 watts Required power is 1500 watts 1500/200=7.5 nearly 8 solar panels are required Cost calculation 10 Components Unit cost ₹ quantity Total cost ₹ Solar size 24,000 8 192000 Water pumps 15,000 1 15,000 Battery(120v) 20,000 2 40,000 Converter circuit 1000 1 1000 Overall cost 2,48,000

11. 11 CASE STUDY SOLAR POWERED IRRIGATION SYSTEM COUNTRY CASE STUDY LALPUR The local NGO VASFA started solar powered irrigation system in Bihar state,vaishali dist Lalpur which is semiarid climatic condition .and facing the frequent load shedding and voltage fluctuation. PV pumping system: 6,410 EUR No specific investment into irrigation system Initial funding by Indo-German Energy Program (IGEP) Farmers pay 0.60 EUR/hour for PV pump usage as compared to 1.10 EUR for former diesel pump operation (pool system)

12. APPLICATIONS There is increasing demand for the use of alternate or renewable energy sources to achieve clean and low-cost electricity for agricultural water pumping requirements This system may be proved beneficial for advanced and precision irrigation systems like sprinkler as well as drip irrigation system for small scale farming condition requiring less water requirement . These techniques is especially suitable for region with less water availability and good wind speed like Rajasthan in India.  The major advantage of wind – solar hybrid energy system is that when used together, 12

13. ADVANTAGES Solar and wind energy are pollution free and causes no greenhouse gases to be emitted after installation . Reduced dependence on foreign oil and fossil fuels. Renewable clean power that is available every day of the year even cloudy days produce some power . Return on investment unlike paying for utility bills. Excess power can b sold to the neighbor farmers. Wind turbines have a relatively small land footprint. 13

14. DISADVANTAGES High initial costs for materials and installation. No solar power at night so there is a need for a large battery bank. Cloudy days do not produce much energy . We often hear that wind turbines pose threat to wildlife-primarily birds and bats. Wind energy mainly high only on JUNE, JULY and AUGUST. 14

15. CONCLUSION Easy to implement system and environment friendly solution for irrigation fields Found long successful for bore holes as they can pump over the whole day In run this system is economical. system has an attractive usage for irrigation due to the lowest cost, the highest percent of the sell energy and the highest reduction of Carbon dioxide emission 15
