3. INTRODUCTION
Energy is the biggest issue of this era that is causing the most
controversial concern.
Fossil fuel resources are limited and using them is known to cause
global warming.
Alternative options such as using renewable energy sources.
Energy harvesting is the capture and conversion of small amounts of
readily available energy in the environment into usable electrical
energy.

4. Hence, harvesting energy from nonconventional sources in the
environment has received increased interest over the past few years.
This paper concludes with the use of Smart energy harvesting device i.e.;
SOLAR TRACKING SYSTEM.

7. HOW CAN WE MOST EFFECTIVELY CAPTURE,
CONVERT AND STORE THIS TREMENDOUS
NATURAL RESOURCE?
Solar cells are used for the mentioned purpose.
Solar cells also known as Solar Photovoltaic cells or
Photoelectric cells.
These cells convert the solar radiation into D.C electricity ,which
can be either used as it is or stored in the
battery for use at night.

9. INTRODUCTION TO SOLAR TRACKING
SYSTEM
 Solar panel indeed provide sufficient energy to store, which is
maximum 24.5% efficient.
 Stationary panels used, are capable of getting maximum input source
only when sun is on the head.
 The alternative approach for providing better efficiency and rotation
according to sun’s positioning led to the designing of tracking system.

10. What is solar tracking system?
 A solar tracker is a device used for orienting solar panel or for
concentrating solar reflector or lens toward the sun by using solar or light
sensors connected with the machine (ex: stepper motor, servo motor, etc).
 Hence, the sun tracking system collects more energy than what a fixed
panel system collects increasing efficiencies up to 40-60%.
 These devices change their orientation throughout the day to follow the
sun’s path to maximize energy capture to the full extent.

11. COMPONENTS
 Light dependent resistor (LDR)
 Microcontroller
 Motor (servo, stepper, etc)
 Display unit (optional)
 Solar panel

12. THE WORKING
 Interfacing between hardware and
microcontroller
 Inputs to microcontroller
 Controlling constraints

15. APPLICATIONS
 Can be used for small & medium scale power generations.
 For power generation at remote places where power lines are not
accessible.
 For domestic backup power systems.

16. CONCLUSION AND FUTURE
SCOPE
 Automatic solar tracking system offers a prototype for implementing a
large array type solar tracker.
 It has been proven that solar tracking system with single axis freedom
can increase energy output by approximately 40%.
Further mechanical enhancement can be done to the prototype, to
implement dual axis tracker.
 Larger solar panel must be integrated with the system to prepare better
result, cost analysis and use of renewable energy to cope up with the
demand.
