Description
In this project, LDR’s are working as light detectors. Before we go into detail, we will have to understand how the LDR’s work. LDR (Light Dependent Resistor) also known as photo resistor is the light sensitive device. Its resistance decrease when the light falls on it and that’s why it is frequently used in Dark or Light Detector Circuit. Check the various circuits based on LDR here.
The two LDR’s are placed at the two sides of solar panel and the Servo Motor is used to rotate the solar panel. The servo will move the solar panel towards the LDR whose resistance will be low, mean towards the LDR on which light is falling, that way it will keep following the light. And if there is same amount of light falling on both the LDR, then servo will not rotate. The servo will try to move the solar panel in the position where both LDR’s will have the same resistance means where same amount of light will fall on both the resistors and if resistance of one of the LDR will change then it rotates towards lower resistance LDR. Check the Demonstration Video at the end of this Article.
HIGHLIGHTS
- When sun rays fall on Photo voltaic panel, Panel converts it in to electrical energy
- If we mount solar panel at single angle & position we will be unable to utilize 100% solar energy.
- To achieve the above target we need to rotate solar panel as sun moves from east to west.
- Servo Motor

I needed a electrical project for final year so I went for this project, the project was well tested also it is in plug and play condition. And it’s impressive as it gives almost accurate results.
