The document discusses a project seminar on a solar panel system equipped with a dual-axis sun position tracking mechanism. It highlights the advantages of solar energy as a renewable and cost-effective power source, emphasizing its potential to mitigate energy crises through improved efficiency. The dual-axis tracker is noted for its ability to increase energy output by approximately 30-40%, though it may require more maintenance and has a higher initial cost compared to stationary systems.

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.
