INTRODUCTION

• Subsequent development of the solar cell, which is a semi-conductive material that converts visible light into a direct current.

• A Solar tracker is a device used for orienting a solar photovoltaic panel or lens towards the sun by using the solar or light sensors connected with the machine.

WHAT IS A SOLAR TRACKER ?

• A solar tracker is a generic term used to describe devices that orient or align various payloads toward the sun.

• The system focuses on the optimization of the electric energy produced by photovoltaic

cells

WHY USE SUN TRACKER ?• Global warming has increased the demand and request for green

energy produced by renewable sources such as solar power.

• To increase efficiency up to 40% by using of tracker as compare to fixed solar panel.

• We see a performance gain of 25-35% by using single axis tracker

& double-axis solar trackers, performance goes up additionally 5-10%.

BASIC COMPONENT

• The Solar Panel• Stepper Motor• Actuator • Microcontroller• A Display Unit (Optional)• Interfacing Cables

STEPPER MOTOR

• A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements.

ACTUATOR

• An actuator is a type of motor that is responsible for moving or controlling a mechanism or system.

• It is operated by a source of energy, typically electric current, pneumatic pressure, and converts that energy into motion.

MICROCONTROLLER

• A microcontroller is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.

CONDITION FOR MAXIMUM OUTPUT

• The difference between the incident ray and the reflected ray should be equal to zero, i.e. the rays should be perpendicular to the panel.

• The altitude is directly proportional to the efficiency of the system up to a certain limit.

• Very clear sky and clean atmosphere contributes a bit more to the efficiency of the system.

APPLICATION OF SOLAR TRACKER SYSTEM

• 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.

ADVANTAGE OF SOLAR POWER• Solar tracking systems continually orient photovoltaic

panels towards the sun and can help maximize your investment in your PV system.

• One time investment, which provides higher efficiency & flexibility on dependency over other sources.

• Tracking systems can help reducing emissions and can contribute against global warming.

• Bulk implementations of tracking systems help reduced consumption of power by other sources.

• It enhances the clean and emission free power production.

DISADVANTAGE OF SOLAR POWER

• Initial investment is high on solar panels.• It’s a bit of difficult for servicing, as the

tracking systems are not quite popular regionally.

• Moving parts and gears which will require regular maintenance.

• May require repair or replacement of broken parts over a long run.

CONCLUTION

• On one hand we can see the worlds energy resources depletion to be a major problem.

• On the other hand global warming, which is a major concern.

• Switching to solar power, which is clean and green and enhancing its efficiency by using sun trackers is a great option in the near future
