  1. 1. AUTOMATIC SOLAR TRACKING SYSTEM USING INTERFACING IC AND GEARED MOTOR PROJECT GUIDE: PROF. K.UMADEVI /HOD,EEE PROJECT MEMBERS: R.GOVINDARAJU (110406625013) GOVINDARAJU.R (110406625013) LOGU .M (110406625021) NITHYAKUMAR.R (110406625025) PALANISAMY.M (110406625027) ELECTRICAL AND ELECTRONICS ENGINEERING EXCEL COLLEGE OF ENGINEERING AND TECHNOLOGY ANNA UNIVERSITY: CHENNAI 600 025
  2. 2. ABSTRACT  Solar tracking systems are the most appropriate and proven technology to increase the efficiency of solar panels by keeping the panels aligned with suns position with the help of interfacing IC and Geared motor. In this project an interfacing IC is used to make the system as automatic solar tracker. Geared motor helps to adjust the axis of the solar panel both vertical (X) and horizontal (Y) position without any sensor and programmable IC unit.

  4. 4. EXISTING SYSTEM  Only automatic control  Memory used , cost wise high  Stepper motor used, less load applications only
  5. 5. PROPOSED SYSTEM  Both automatic and manual  Maintenance is less  Geared motor used , large load applications

  8. 8. Dual Axis Trackers  Double axis solar trackers have both a horizontal and a vertical axle and so can track the Sun's apparent motion exactly anywhere in the world.  Dual axis trackers track the sun both East to West and North to South for added power output (approx 40% gain) and convenience
  9. 9. LIGHT DEPENDENT RESISTOR  Used to sense or detect light  Resistor whose resistance decreases with increase in intensity of light  Made of high resistance semiconductor
  10. 10. COMPARATOR A comparator is a device that compares two voltages or current and outputs a digital signal indicating which is larger. It has two analog input terminals -v and +v and one binary digital output v0
  11. 11. MOTOR DRIVING CIRCUIT L293D L16-pin IC which can control a set of two DC motors simultaneously in any direction. It means that you can control two DC motor with a single L293D IC. Dual H-bridge 293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a Motor Driver integrated circuit (IC).

  13. 13. GEARED MOTOR  Two geared motors in X and Y direction  Used to transmit torque to the panel arrangement
  14. 14. ADVANTAGES  More efficient compared to normal arrangement.  Energy output increases up to 30-40% than normal stationary. arrangement.  High degree of accuracy.  Eco friendly.
  15. 15. USES  For solar photovoltaic (PV) panel applications  For solar thermal dish/engine applications
  16. 16.  From our project, it helps to increase the efficiency of output power up to 30 to 45% without using sensor and programmable IC unit. This project can able to use illiterate people also.  There is no requirement of technician for solving problem occurring in the project reinstallation after updating the advancement process in solar energy conversion system. Here we can easily upgrading the project for future enhancement also
