3.  Solar cells are becoming extremely popular for
utilizing energy .
 So many solar panels have been installed all over
the world and most of them are stable.
 Many researches were conducted to
develop some methods to increase the efficiency of
PV system.

4.  Now the problem arises that the sun
moves.
 Solar panels are stationary and do
not follow the movement of the sun
and hence cannot obtain maximum
sun light throughout the day

5.  The objective of this project is to control the
position of a solar panel in accordance with
the motion of sun.
 The main objective of this project is to catch
maximum solar radiation from the sun, and
increase the efficiency solar panel.

6.  A Solar tracker is a device used for
orienting asolar PV panel by using
LDR sensors connected with the
panel.
 By this PV panel get maximum
intensity of sun light

7.  SOLAR PANEL
 LDR SENSORS
 DC MOTOR
 CONTROL UNIT

8.  Convert solar energy to electricity.
 Its made up of a number of solar cells
connected in series internally.
 Based on photo voltaic effect.
 Specification : 0.7Watt
Length - 7CM
Width- 5CM
Cell material – silicon crystal

9.  LDR sensor are used for detect the
intensity of light.
 In our project two LDR sensor are
used.

10. 3. DC MOTOR
 Its an electromechanical device which converts
electrical pulse in to mechanical shaft rotation.
 It can drive one rotation in many steps.
 In our project two stepper motors are
used.
 Specification :
6V DC moter

11.  It is a brain of the system
 A control unit handles all
processor control signals
 Relay circuit are used as a
control unit.
 Cost of control unit

12.  In this project we are used wiper for cleaning
solar plate automatically.
 By this system we make the life of this plate
longer then other plates.
 Increase efficiency of solar plate approx 20%
 Requirement :
 Stepper motor 12v
 foam
 switch

15. The system focuses on the controller design where the
system is able to track the maximum intensity of Sunlight.
When the intensity of Sunlight is decreasing, this system
automatically changes its direction to get maximum
intensity of Sunlight.
 LDR sensor is used to track the sunlight by detecting
brightness level of Sunlight.
While to rotate the appropriate position of the panel, a
DC motor is used.

18.  Maximum utilization of solar energy.
 Max. solar energy saving
 It is clean and emission free power production.
 External power supply is not required.
 Increase 40% efficiency of solar power plant.

19.  Street lights
 International space station
 Solar cars
 These can be used in home to power the appliances
using solar power.
 These can be used in industries as more energy can be
saved by rotating the panel.
