2. INTRODUCTION
A solar tracking system can be used as a power generating
method from sun light.
This tracking system play important role for power
generation by setting the equipment to get maximum
intensity sunlight automatically.
When there is decrease in intensity of light , this system
automatically changes its directional to gets maximum
intensity of light

4. What is a solar tracker ?
A solar tracker is a device that track of the sun. it follows
the path of sun through out daytime with the help of sensors
The sun position in the sky changes with the time and
altitude angle and azimuth angle various continuously ,
Solar tracker are used for solar panels in solar power plants
where energy generation is describable up to maximum limit

5. TYPES OF SOLAR TRACKER
Solar tracking system is classified by its degree of
rotation. According to degrees of rotation trackers can be
grouped in two primary categories.
Single Axis Solar Tracker
Dual Axis Solar Tracker

6. Single Axis Tracker
A single axis solar tracker follows the movements of sun
either horizontally or vertically. This type of tracker has
only one axis for rotation
The horizontal type solar tracker is used in tropical
regions where the sun gets very high at noon , but the day
are short. On the other hand
The vertically type solar tracker is used In areas with high
altitude where the sun does not get very high , but
summer days can be very long
In concentrated solar power application single axis solar
tracker are used with parabolic and linear fresnel mirror
designs

7. DUAL AXIS SOLAR TRACKER
A dual axis solar tracker has two degrees of rotation . It
can track sun both horizontal and vertical
This type of solar tracker can be used any where in the
world and achive maximum efficiency in gaining solar
energy
Concentrated solar power application using dual axis
tracking is extremely important in solar power tower
application
Design for dual axis tracking system is complex than single
axis tracking and operation is more energy consuming

9. Need for a sun tracking system
Global warming has increased the demand and request
for green produced by renewal sources as solar power.
Solar energy has been the power supply of choice for
industrial application where power is required at remote
location.
Solar tracking is increases applied as a effective power
generation.

11. Condition for maximum output
The difference between the incident ray and reflected ray
should be equal to zero, i.e the ray should be
perpendicular to each other
The altitude is directly proportional to the efficiency of
the system up to the certain limit
Very clear sky and clean atmosphere contributes a bit
more to the efficiency of the system.

13. Working Of Solar Tracker
There are two different driver that dictate the motion of
the tracker :passive and active.
Passive trackers depend solely on solar heat to guide and
move the tracker .
Active tracker used a controller that monitors the position
of the sun movements in order to direct motors that’s
moves the tracker
In most solar trackers LDRs are used as sensor ,there
different in output is generat error signal. In these
system

15. The Input
The various positions of the sun over a year for a
particular geographical location is given as the primary
input to the microcontroller.
The irradiance of the sun for a particular geographical
location over a year is the input of microcontroller
The real time clocking is enabled in the microcontroller

16. Advantage
Solar tracking system continually orient photovoltaic panels towards the sun
and can maximize your investment in your pv system
One time investment, which provided maximum efficiency and provided
flexibility on dependency over other sources.
Bulk implementation of tracking system help reduced consumption of power
by other sources.
Tracking system can help reducing emission and can contribute against
warming
It enhances the clean and emission free power production

17. Disadvantage
Initial investment is high on solar panel , motor and any
other devices .
Moving parts and gears which will require regular
maintenance.
May require or repair or replacement of broken parts over
a long run.

18. Application
Can be used for small & medium scale power generation .
For power generation at remote places where power lines
are not assessable
For domestic backup power system.

19. Conclusion
On one hand we can see the worlds energy resources
depletion to be a major problem
On the other hand global warming , which is major
concern .
Switching to solar power , which is clean and green and
enchancing its efficiency by using sun tracker is a great
option in the near future.
