ABSTRACT

• Cost effective solar power can be theanswer for all our energy needs. Solarpowered smart irrigation systems are theanswer to the Indian farmer. This systemconsists of solar powered water pumpalong with an automatic water flow controlusing a moisture sensor. It is the proposedsolution for the present energy crisis for theIndian farmers. This system conserveselectricity by reducing the usage of gridpower and conserves water by reducingwater losses.

Block Diagram of Smart Irrigation System

• 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.

• A valve is controlled using intelligent algorithm in which it regulates the flow of water into the field depending upon the moisture requirement of the land. In this system we use a soil moisture sensor that detects the amount of moisture present in the soil and depending upon the requirement of level of moisture content required for the crop the water flow is regulated thus, conserving the water by avoiding over flooding of crops.

LITERATURE REVIEWEnergy Use in India For Irrigation

• According to the survey conducted by theBureau of Electrical Energy in India in 2011 thereare around 18 million agricultural pump sets andaround 0.5 million new connections per year isinstalled with average capacity 5HP.

• Total annual consumption in agriculture sector is131.96 billion KWh (19% of total electricityconsumption).

• So solar powered smart irrigation technique isthe future for the farmers and a solution forenergy crisis.

RESEARCH AND WORK

Improve Efficiency of solar panel

• An organic solar cell or plastic(Polymer Based) solar cell is a type of polymer solar cell that uses organic electronics.

• For photovoltaic devices to compete with fossil fuels for energy collection, they must convert sunlight to energy at a very efficient level. Solar cell conversion depends on excitons, which are electron pairs that are energized by sunlight. These excitons must get to the interface of the donor and acceptor domains as quickly as possible to avoid losing energy as heat.

• The efficiency of polymer-based organic photovoltaic cells depends on the purity of the donor and acceptor domains. So by finding out how pure and large the acceptor domain is and what the interface of the donor domain looks like, efficiency can be increased.

Using Organic and plastic cell Technology we can improve efficiency (42%)of system

Organic solar cell

COST ANALYSIS

• With over nine hundred thousand tube wells being used in every state ofIndia, around Rs.18 Million of energy is used for pumping water forirrigation. This amount of money used for electricity can be saved with thehelp of solar water pump. Annually the cost of nearly five million kilo watthour of energy can be spared. That is around Rs.27 Million per annum can

be redeemed which comes around 40% of the total amount of investment.• Even though the initial investment is high, it can be earned back in 2 and a

half years’ time. If we assume the cost of power is Rs. 1.5 Million per kilowatt hour, Rs.18 Million is used for pumping water alone in a year. By usingthe solar water pump, we can save up to 4.8 million KWh of energyannually which saves a lot of energy. The excess energy can also be givento the grid with small modifications and investments in the circuit, whichcan add to the revenue of the farmer.

Cost AnalysisComponent Unit Cost Quantity Total Cost

Solar Panel (1.4m2) 24000 4 Rs.96000

Converter Circuit 400 1 Rs.400

Battery 24V,100Ah 8250 1 Rs.8250

Overall cost Rs.104650

Result Compare to Normal system

• 1. Low operating cost: One of the important advantages is thenegligible operating cost of the pump. No fuel required

• 2.Low maintenance: A well-designed solar system requireslittle maintenance beyond cleaning of the panels once a week.

• 3.Harmonious with nature: Another important advantage isthat it gives maximum water output when it is most neededi.e. in hot and dry months. Slow solar pumping allows us toutilize low-yield water sources .

• 4.Flexibility: The panels need not be right beside the well.They can be anywhere up to 20 meters

limitations

• 1. Low yield: Solar pumping is not suitable where the requirement is very high.

• 2.Variable yield: The water yield of the solar pump changes according to the sunlight. It is highest around noon and least in the early morning and evening. This variability should be taken into consideration while planning the irrigation.

• 3.Water quality: As with any other pump, solar pumps work best if the water is clean, devoid of sand or mud. However, if the water is not so clean, it is advisable to clean the well before installation or use a good filter at the end of the immersed pipe.

• 4.Theft: Theft of solar panels can be a problem in some areas. So the farmers need to take necessary precautions. Ideally, the solar system should insured against theft as well as natural hazards like lightning.

Conclusion

• By implementing the proposed system there are various benefits forthe government and the farmers. For the government a solution forenergy crisis is proposed. By using the automatic irrigation system itoptimizes the usage of water by reducing wastage and reduce thehuman intervention for farmers.

• To further enhance the daily pumping rates tracking arrays can beimplemented. This system demonstrates the feasibility andapplication of using solar PV to provide energy for the pumpingrequirements for sprinkler irrigation. Even though there is a highcapital investment required for this system to be implemented, theoverall benefits are high and in long run this system is economical.
