    3. 3. ABSTRACT  Extracting useable electricity from the sun was made possible by the discovery of the photoelectric mechanism and subsequent development of the solar cell.  Light gathering is dependent on the angle of incidence of the light source providing power (i.e. the sun) to the solar cell’s surface and the closer to perpendicular, the greater the power.  we see the need to maintain the maximum power output from the panel by maintaining an angle of incidence as close to 0 as possible.
    4. 4. “SOLAR TRACKING SYSTEM” - Used to control and set the moment of solar panels. This system uses DC motor to control the angle of rotation of the panels. Rotation of DC motor through the desired angle is achieved by using Kiel cross compiler. INTRODUCTION
    5. 5. PROJECT BACKGROUND Why should the solar panel face the most illuminating source of light?  TO Increase Solar Panel Output  Maximize Power per unit Area
    6. 6. Main Objectives  Position the Solar Panels so that they will acquire maximum energy from a light source.  Store the acquired energy into batteries, and use the batteries to control the rest of the system when the solar energy is absent.  In no-light or low-light conditions design the system to go into sleep mode so that energy is not wasted.

    15. 15. LIGHT Dependent RESISTOR  Light sensors are among the most common sensor type.  The sun tracker uses a cadmium sulfide photo cell for light sensing .  To utilize photo cell, it is placed with a resistor.
    16. 16. ANALOG TO DIGITAL CONVERTER [ADC] Features of ADC Key Specifications 0809ADC  Hi-speed  High accuracy  Easy interface to all microprocessors  Resolution 8-bits  Single supply 5v DC  Low power 15mW
    17. 17. MOTOR DRIVER CIRCUIT
    18. 18. DC SERIES MOTOR WHAT DOES DC SERIES MOTOR DO Like any other motor, series motors convert electrical energy to mechanical energy. Its operation is based on simple electromagnetic principle by which when the magnetic field created around a current carrying conductor interacts with an external magnetic field, a rotational motion is generated. A typical DC motor layout is given in the following diagram:
    19. 19. FEATURES:  Rpm : 300 at 12v  DC supply: 3 to 12V  Output shaft: Centre.  Motor diameter: 38 mm.  No-load current = 60 mA, Load current = 300 mA
    20. 20. LCD DISPLAY  Interface with 4-bit/8-bit microprocessor. Display data ram [80 characters].  Character generator rom [160 characters]. .
    21. 21. APPLICATIONS  Used in water heaters. Used in inverters[AC-DC]. ADVANTAGES  The solar tracker system provides numerous applications in the field of industrial.  Its main application lies in the industrial processes like energy stations and powerhouses for the production of electricity. DRAWBACKS  Tracker is effected by temporal variation in atmospheric refraction caused by rain, cloud.  It leads to wrong positioning of solar panel.
    22. 22. CONCLUSION To collect greatest amount of energy from sun, solar panels must be aligned orthogonally to sun. For this purpose a new solar tracking technique based on micro- controller was implemented and tested in this study.
