solar tracker device

1. Dual Axis Solar Tracker

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

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

6. • Dual axis solar trackers have
both horizontal and a vertical
axle and so can track the
Sun's apparent motion
exactly anywhere in the
world.
DUAL AXIS SOLAR TRACKER :
•Dual axis trackers track the sun
both East to West and North to
South for added power output
(approx 40% gain) and
convenience.
