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. •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. Commercial purpose •Increase solar panel output •Maximize power per unit area •Able to grab energy throughout the day
- 7. • 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 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.
