This document summarizes a project report on developing a dual-axis solar tracking system using an Arduino. The system uses light dependent resistors and servo motors controlled by an Arduino to position a solar panel to always face the direction that receives the maximum sunlight. This allows the system to maximize the amount of solar energy collected. The project aims to develop an efficient solar tracking system to help address energy issues. It provides advantages like increased flexibility and accuracy in positioning compared to fixed panels. The system has applications for power generation in remote areas, street lighting, vehicle charging and more.

3. INTRODUCTION
Solar energy is rapidly advancing as an important means of
renewable source of energy.
In verge of a major energy crisis, as energy consumption is
increasing day by day and energy sources are depleting.
Solar energy is universally accepted renewable energy
source, which can used to avoid the energy crisis.
An eco-friendly method of utilizing solar energy for
maximum energy consumption is dual axis solar tracker.

4. What is Solar Tracker?
 Solar tracker tracks
maximum solar energy.
 This energy can used b
y
converting it into other
forms.



5. IMPROVEMENTS
 We can able to collect the maximum solar energy since it
is Dual axis tracker.
 The speed of the servo motor and the movement of the
solar panel is controlled by using the arduino
 Thistracker will be more efficient than the above
mentioned trackers.

6. AIM OF THE PROJECT
 To utilize the maximum solar energy by using solar
panel.
 And hence to develop a arduino based dual axis solar
tracker.

7. COMPONENTS
 Solar Panel
 Servo Motor
 Light Depend Resistors
 Arduino system

9. WORKING
 When sunlight incident on the solar tracker, it starts
calculating and comparing that from which direction
the maximum intensity sunlight is coming.
 After comparing the panel above the system start to
move toward the maximum intensity so that the
solar panel has the maximum intensity and makes
the maximum power.
 “The maximum intensity of light directly
proportional to the maximum power convert ”.

10.  There we are using the LDR which is known as the
Light dependent resistor when the sunlight incident the
LDR the resistor value of the LDR will decrease.
 It means it only controls the resistance by using light.
so, we are using this method. which LDR decreases the
maximum resistor the dual-axis solar tracking
system will move in that direction.
 This is the principle of this project there we are using
two servo motors which help to move the panel in all
directions. Arduino, help to make all processing.
calculation etc.
WORKING

11. APPLICATIONS
 Street light applications with out using normal power
supplies.
 In Remote areas implementing a small power systems
units at each home.
 Using this system to getting hot water.
 It can be used in Vehicles for Battery charging.

12. ADVANTAGES
 High degree of flexibility since it moves in two directions.
 Its flexibility allowing for higher energy output
during Sunny days.
 Higher degree of accuracy in directional point.
 Eco-Friendly.

13. CONCLUSION
 We presented a means of tracking the sun’s position with
the help of arduino. Specially, it demonstrates a working
solar tracker for maximizing solar cell output by
positioning a solar panel at the point of maximum light
intensity i.e., when Panel is Perpendicular to the Solar
energy.
 Solar tracking system is more efficient than any other
ordinary panel.
 It is possible to reduce the energy crisis to some large
extent.
