Circuit Schematic Solar Tracking Solar Panel Based on ATMEGA8 Micro controller

Eltronicschool. - There are many circuit schematic designed using solar panel for many application. One application is for solar tracking based on ATMEGA8 microcontroller. In here we will give you specific circuit schematic using solar panel is Circuit Schematic Solar Tracking Solar Panel Based on ATMEGA8 Micro controller like in figure 1 below.

Circuit schematic

Component Parts

  • Solar panel
  • ATmega8 micro controller
  • Light Dependent Resistor.
  • Motor driver I
  • Stepper Motor.
Description

Circuit schematic like in Figure 1 above is Circuit Schematic Solar Tracking Solar Panel Based on ATMEGA8 Micro controller. According Electronicshub site describe that the Sun tracking solar panel consists of two LDRs, solar panel and stepper motor and ATMEGA8 Micro controller.

Two light dependent resistors are arranged on the edges of the solar panel. Light dependent resistors produce low resistance when light falls on them. The stepper motor connected to the panel rotates the panel in the direction of Sun. Panel is arranged in such a way that light on two LDRs is compared and panel is rotated towards LDR which have high intensity i.e. low resistance compared to other. Stepper motor rotates the panel at certain angle.

When the intensity of the light falling on right LDR is more, panel slowly moves towards right and if intensity on the left LDR is more, panel slowly moves towards left. In the noon time, Sun is ahead and intensity of light on both the panels is same. In such cases, panel is constant and there is no rotation.

How Sun Tracking Solar Panel Works?

  • Initially power the circuit.
  • Place the set up in dark
  • When the two LDRs are in dark, there is no movement in the panel.
  • Now place a torch in front of the left LDR. Panels slowly move towards its left.
  • Now move light from left to right. You can observe the panel moving slowly with the torch towards right.
  • In the middle, when intensity on both LDRs is equal, panel will not move until there is difference between the light intensity falling on the LDRs. Read more here.
