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 is the device
which orients solar panel
towards the Sun.
 The orientation is due to
Light Detecting resistors.
 Solar tracker tracks
maximum solar energy.
 This energy can used by
converting it into other
forms.

6. IMPROVEMENTS
 We can able to collect the maximum solar energy since it
is Dual axis tracker.
 The speed of the stepper motor and the movement of the
solar panel is controlled by using the microcontroller.
 This tracker will be more efficient than the above
mentioned trackers.

7. AIM OF THE PROJECT

10. 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.

11. 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.

12. DIS-ADVANTAGES
 Higher mechanical complexity.
 More expensive than Single axis tracker.

13. CONCLUSION
 We presented a means of tracking the sun’s position
with the help of microcontroller. 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.
system is more efficient than ordinary panels.
