2. • Introduction
• Dual axis tracker
• Block diagram
• Circuit diagram
• Advantages
• Disadvantages
• 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. •Solar power ,the best alternative
for a renewable source.
•Cost effective.
•Improved operating efficiency.
•Unlimited reserve because
source is sun .
Solar panels ,modern
technology of solar
energy absorption
Solar panels absorbs
maximum sunlight and
converts it to electricity

5. • For orienting panel
towards the sun
• Have light sensors and
mechanical arrangement
• Tracks maximum
intensity

6. DUAL AXIS SOLAR TRACKER :
• 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.

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

12. • Two geared motors in X and Y direction
•Used to transmit torque to the panel arrangement
GEARED MOTOR

13. •Standard switching diode
•Low cost, long life and dependable
•Used in switching application up
to
100 MHz

14. • More efficient compared to normal
arrangement.
• Energy output increases up to 30-
40% than normal stationary.
arrangement.
• High degree of accuracy.
• Eco friendly.

15. • Solar trackers are slightly more expensive
than their stationary counterparts .
• Generally more maintenance required
• Extent of cloud cover.
• Damages in storm.

16. • 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.
