Solar Tracking for Automation of Irrigation System

Abstract

Solar energy is considered the most important form of renewable energy resource, as the sun is the main source of energy for our planet Earth. Solar tracking makes sure the sun’s rays are always projected at an angle perpendicular to the solar panel. The main aim of our project is to increase the quantity of energy generated from the solar panel by using an automated Solar tracking system to capture the maximum radiation of the sun i.e., the maximum intensity of the sun’s rays. Our proposed system consists of the development of an automated water pumping system with the help of solar tracking. The proposed method increases efficiency. The power generated from a solar panel is stored in a battery and the power is sent to the water pump only when the soil is dry, this happens with the help of a soil moisture sensor. The solar panel rotates with the help of a DC motor and light-dependent resistor sensors. This is a low-cost project with the embedded system to produce electrical energy from the solar panels by using a microcontroller and sensors light-dependent resistors, where the power required for the automation of the tracking system and the working of the microcontroller is given by the electrical energy which is produced from the sun itself. In rural areas where there are several power cuts, this project can be very useful for the supply of water where the required power is given to the motor from the battery which is charged by the solar panel from its maximum intensity of light which can be tracked by the tracking system.
