1. Solar Tracking System

2.  Introduction  Need for solar tracker  Dual axis tracker  Block diagram  Circuit diagram  Advantages  Disadvantages  Uses  Conclusion 

3. In the verge of a major energy crisis as energy consumption is increasing day by day and energy sources are depleting. Solar energy is a renewable source of energy which can avoid this crisis to an extent. SOLAR ENERGY :  Major Eco-friendly & Pollution less method of producing the electricity today.

4. Commercial purpose Increase solar panel output Maximize power per unit area Able to grab energy throughout the day

5. X DIRECTION MOTOR LIGHT DECTECTOR (X DIRECTION) LIGHT DECTECTOR (X DIRECTION) LIGHT DECTECTOR (Y DIRECTION) LIGHT DECTECTOR (Y DIRECTION) COMPARAT OR MOTOR DRIVING CIRCUIT Y DIRECTION MOTOR SUNLIGH T SOLAR PANEL

6. Used to sense or detect light Resistor whose resistance decreases with increase in intensity of light Made of high resistance semiconductor

7. + outpu t input Vref

8. Have four digital comparators in one IC Output will be either high or low Uses single supply unlike other comparators

9. L293D

10. H bridge motor driving circuit Controls two motors in both direction Takes digital input

11. Two geared motors in X and Y direction Used to transmit torque to the panel arrangement
