SINGLE AXIS SOLAR PANEL CONTROLLER AND POWER OPTIMIZATION

 

INTRODUCTION

            Usually ordinary solar panel is always faces only in one direction. Because of this reason the solar panel may not get sufficient sun rays to work. The project SOLAR PANEL CONTROLLER AND POWER OPTIMIZATION is done in order to overcome this defect. Here the panel will rotate according to the readings read by the LDR. So it will utilize the full sun light to work & power optimization is also done by using the LDR.  

 

DISCRIPTION

This project is mainly designed to control the solar panel automatically, maintains face of the solar panel towards the sun. This is done by controlling the mechanical movement of the solar panel. Usually sun rises at east and sets at west. In ordinary system, if it faces towards east then it cannot change the direction towards sun during sunset. Because of this reasons solar panel may not get sufficient sun rays to work.

These problems are overcome by using this project. In this project we also build a very good micro controller based solar charger. The mechanical movement of the solar controlled through the stepper motor. 5 LDR’s will be placed on arch. So according to the sun movement LDR intensity will be varied where the sun light intensity is more LDR intensity will be less and depending upon LDR intensities stepper motor will be rotated to the side where the LDR intensity is found to be less so that solar panel is also rotates.

          Power optimization is done by using LDR. If the surrounding light is less then LDR reads maximum. According to the value of LDR the ADC shows the reading. The ADC will send this value to microcontroller. According to the value sent by the ADC the microcontroller glows the LED through relay. If the intensity of the light is more means all the LED array will be OFF. Depending upon the intensity of the light LED array’s will be switched ON or OFF

          8051 architecture based P89V51RD2 microcontroller from NxP is used to implement this project. Microcontroller acts as the heart of the project, which controls the whole system. It contains 1k RAM, 64k Flash, 3 Timers, 2 external interrupts, 1 UART, 32 GPIO’s, ISP programming support etc. KEIL IDE is used to program the microcontroller and the coding will be done using Embedded C.
