The power consumption of any equipment is an important to reduce the cost of production. In this project, the overall power consumption rate will be reduced by using the components such as moisture sensor, water pump which is solar powered, float switch controlled water tank, and an automatic water flow control system. Thus, the implementation of the system reducing the usage of grid power and conserves electricity and reducing water losses and conserves water.

This solar radiation strike the earth surface the amount of solar radiation received by the earth surface is around 1367 watt per square meter. These solar radiation can be used for several purposes like heating, power production solar heating can be by using flat plate collectors which absorbs and transfers heat to a fluid (water or air).solar power production involves the use of photovoltaic cells to convert solar radiation into electricity for further utilization. Solar energy is also a renewable source of energy which is cost free and excessively available in nature and most importantly it is eco-friendly. Our system makes uses of this solar radiation to produce power which runs a agricultural water pump. Thus the power required to run the pump is eliminated which removes the dependency of farmers on grid power. 1.1 Literature review Concept of conventional irrigation: The conventional irrigation methods are controlling the flow direction of water by using paths and sand barriers manually by farmers. By using these method a larger amount of water is needed for irrigation and also wastage of water is also high and a lot of manual work is to be done by the farmers. Concept of sprinkler irrigation: Sprinkler irrigation involves the use sprinklers which is placed at various places of the agricultural field. Water pump delivers pressurized water to the sprinkler. Water is sprayed into the air through sprinklers so that it breaks into small water drops that falls down on the agricultural field. The total energy consumption of agricultural sector 132.1 billion Kwh which is 19.4% of total energy consumption. There are around 18 million agricultural water pump sets in India along with 0.5 million new pump connections every year.by implementation of the proposed solution energy consumed by agricultural pump sets can be reduced. [2] 2. Methodology This irrigation system has two main modules- Solar pumping module and automatic irrigation module. Solar pumping module: Solar pumping module has the following components solar panel, control circuit, battery and a water pump powered by solar energy. solar panels of required capacity is used to generate electrical energy that is used to drive the water pump. convertor circuit is used to convert the direct current produced from the solar panel into alternating current. battery is used to store the direct current produced from the solar panel. Automatic irrigation module: An automatic irrigation module has the following components stepper motor, moisture sensor and a control circuit for stepper motor. stepper motor controls the outlet of the water tank. stepper motor is driven by the control circuit which gets signal form the moisture sensor according to the moisture level in the field. if moisture level is low on the field the signal received by the control circuit actuates the stepper motor to open outlet of the water tank. If the moisture level in the field is sufficient by using the signal from the moisture sensor the driver circuit controls the stepper motor to close the outlet of the water tank. Components Used: Solar Panel Battery Convertor Circuit Water Tank with float switch Moisture Sensor Automatic valve regulation A. Solar panel: Solar panel is a electrical device that generates electrical energy when exposed to solar radiation. The amount of solar power produced depends upon the intensity of solar radiation, size of the solar panel and the efficiency of the solar panel. The most commonly used material for
