  1. 1. Presentation OnPresentation On Capstone Project (Part –I)Capstone Project (Part –I) (Closed Loop Solar Tracker)(Closed Loop Solar Tracker) Prepared By: Vinayak Kumar Manpreet Kaur Kunal Paul Shiv Yadav Manoj Kumar
  2. 2. IntroductionIntroduction   • Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. • One of the most popular renewable energy sources is solar energy. • Many researches were conducted to develop some methods to increase the efficiency of Photo Voltaic systems (solar panels). • This project deals with a microcontroller based solar panel tracking system. • Solar tracking enables more energy to be generated because the solar panel is always able to maintain a perpendicular profile to the sun’s rays.
  3. 3. Project ObjectivesProject Objectives Some of the objectives to meet are:  To design an effective sensor array to provide directional information to guide a major drive system to track the movement of the sun across the sky.  The drive will have to position a photo-voltaic panel to the best angle of exposure to sunlight for collection of solar energy. To present and run the Solar Tracker during the end- of-the course presentation.
  4. 4. Solar PanelsSolar Panels Solar panels are devices that convert light into electricity. Solar cells or PV cells rely on the photovoltaic effect to absorb the energy of the sun and cause current to flow between two oppositely charge layers. A solar panel is a collection of solar cells. Crystalline silicon and gallium arsenide are typical choices of materials for solar panels.
  5. 5. Solar TrackerSolar Tracker A solar tracker is a device onto which solar panels are fitted which tracks the motion of the sun across the sky ensuring that the maximum amount of sunlight strikes the panels throughout the day.
  6. 6. Need Of Solar TrackerNeed Of Solar Tracker Commercial purpose  Increase Solar Panel Output Maximum efficiency of the panel  Maximize Power per unit Area Able to grab the energy throughout the day .
  7. 7. Types of solar trackersTypes of solar trackers Single Axis Solar Tracker Dual axis solar Tracker
  8. 8. Methods of DriverMethods of Driver  Active Trackers :Active Trackers use motors and gear trains to direct the tracker as commanded by a controller responding to the solar direction.  Passive Trackers :Passive Trackers use a low boiling point compressed gas fluid that is driven to one side or the other (by solar heat creating gas pressure) to cause the tracker to move.  Chronological Tracker :Chronological Tracker counteracts the earth's rotation by turning at an equal rate as the earth, but in the opposite direction.

  11. 11. LDRLDR  Light Dependent Resistor (LDR) is made of a high- resistance semiconductor.  It can also be referred to as a photoconductor.  If light falling on the device is of the high enough frequency, photons absorbed by the semiconductor give bound electrons enough energy to jump into the conduction band.  The resulting free electron (and its hole partner) conduct electricity, thereby lowering resistance.
  12. 12. DC MotorDC Motor • A DC motor is a mechanically commutated electric motor powered from direct current(DC). • DC motors are cheaper to buy. • Simple to drive but they need feed- back sensors to allow control of the speed. • It is necessary to detect the rotation of the wheels by means of sensors.
  13. 13. L293DL293D • L293D is a dual H-bridge motor driver integrated circuit (IC). •Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. • This higher current signal is used to drive the motors. •When an enable input is high, the associated driver gets enabled. •when the enable input is low, that driver is disabled.

  17. 17. Pros And Cons Of SolarPros And Cons Of Solar Tracking SystemTracking System PROS: • Produces no pollution. • Solar power produces electricity very silently. • Chance to harness electricity in remote locations that are not associated with a national power grid. • Installing solar power panels in remote locations is generally much less expensive. •High efficiency.
  18. 18. Cons:Cons: • High initial price of solar panels. • Repairs and maintenance • Damage in a storm • Moving parts and gears require regular maintainance
  19. 19. ConclusionConclusion As we know that our country (India) have one of the great problem of electricity now a day, specially in ruler areas .electricity is a pillar of any country ,we just want our project becomes ray of hope of those People which really deserved it. Here,Our main aim is to find low cost and accurate closed loop solar tracker which is fully Automatic .
