The purpose of this project is to design and construct a solar tracker system that follows the sun direction for producing maximum out for solar powered applications using arduino. Achieving balance between power consumption and power production is a bigger challenge today. The best way to solve this imbalanced equation is to use solar energy as efficiently as possible. The problem in the usage of solar energy is with solar cell panel should be exposed maximum to the sun light. If the solar panel is fixed in a particular direction then the sun light intensity varies from morning to evening. Moving the solar cell panel in the direction of sun can increase the solar energy generated from the solar cell. This project consists of few sun light sensors and a motorized mechanism for rotating the panel in the direction of sun. Arduino based control system takes care of sensing sunlight and controlling the motorized mechanism. This system works continuously without any interruption. The main controlling device of the project is Aduino uno microcontroller which LDR’s and servo motor with panel setup is interfaced. The Microcontroller gets input from LDR sensors regarding the direction of sun and controller process this information and controls the movement of solar panel attached to servo motor. This solar energy is stored into the battery. This system runs with battery power. The Microcontroller is programmed using powerful Embedded C language.    

The main object of this project:

• Design a single axis solar tracker.
• Conservation of Non Renewable energy sources.
• Maximum output can be obtained.
• Using of arduino to archive this task.
