Abstract - As we can see now effect of the global warming
earth became a hot s here we can take an advantage from the effect of the global warming we can use energy as an electrical energy to operate an electrical appliance. The problem that we can see now is the most of the solar panel that had been used by a user just only in a one direction. If the solar panel located at east and the sun is located at west. The solar panel cannot be charged so the project that want to develop here is called solar tracking system. Solar tracking system is the project that used AVR microcontroller (atmega16) as a brain to control the whole system. The LDR (Light Dependent Resistor) had been used to sense the intensity of light at 30 degree each or 180 degree total and send a data to the AVR microcontroller. This AVR microcontroller will compare the data and rotate the servomotor in right/middle / left direction. The servomotor rotate the solar panel based on the highest intensity of light and display the output voltage on the LCD. This system is suitable to be used in home or small factories that want to save their budget for long term. Key Words: LDR, microcontroller.
Solar
panel,
servomotor,
This project use 3 sensors in a three direction to sense the direction of maximum intensity of light. Its sensor will face 30 degree so the total angle that the system can sense is 180 degree. This system will use AVR microcontroller as a brain to operate this system and servomotor to rotate the solar panel. And the angle/direction of solar panel will be shown on the LCD. Sun light emits sun rays. Then LDR sensor detects the sun rays. And give the information to AVR microcontroller. Then AVR microcontroller compares the intensity of light. As if the {LDR1 > LDR2} then it rotates to right direction. And if {LDR2>LDR1} then it rotates to left direction. And it gives the command to servomotor. And as per the instructions servomotor moves the panel to left or right. The project output voltage is displayed on the LCD.

1. INTRODUCTION Sun is the essential source of energy. It is the renewable source of energy and it is free of cost. Now a days fossil fuels are limited. Fossil fuel are costly and they causes lots of pollution as compared to sun energy. As we know that sun energy is free of cost and does not cause any kind of pollution. To avoid this drawbacks of fossil fuel we use solar energy. Solar energy is becoming an important energy source as petroleum based resources become more expensive. Solar energy is now abundant and solar technology is growing as more and more people put solar energy to work. Previous type of solar tracking system was fixed system. Solar panel which are used in this systems are only in one way direction. And this system generates low power at the output. As we can see there are many problem that occurs in the previous solar system. To overcome these drawbacks solar tracking system is used. Solar tracking system can detect a 180 degree of rotation so panel can generate high power at the output. It can store more energy. Š 2017, IRJET

1.2 Objective of Project: The main objective of project is to rotate solar panel through the LDR by using servo motor. We have proposed solar panel to control the panel that it should face the sun till it is present in a day.
2. Analogy Table below shows the parameter of solar tracking system & previous type of solar system.
