Solar Tracking System

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

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.

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

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

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

+ outpu t input Vref

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

L293D

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

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

 More efficient compared to normal arrangement.  Energy output increases up to % than normal stationary. arrangement.  High degree of accuracy.  Eco friendly.

 Extent of cloud cover.  Damages in storm.

 For solar photovoltaic (PV) panel applications  For solar thermal dish/engine applications PV PANEL DISH PANEL

 Solar tracking system is more efficient than ordinary panels.  Able to reduce energy crisis to a great extent with effective use of solar energy by means of tracking.
