Seminar on AUTOMATIC SOLAR TRACKING SYSTEM
- 1. “ ” Seminar on automatic solar tracking system Presenting by: Rakesh kumar Branch: Electrical & electronics Under the guidance of Assist . Proff: Mr Sunil sir Department of EN 1
- 2. INTRODUCTION A solar tracking system can be used as a power generating method from sun light. This tracking system play important role for power generation by setting the equipment to get maximum intensity sunlight automatically. When there is decrease in intensity of light , this system automatically changes its directional to gets maximum intensity of light 4/9/2019 2

- 4. What is a solar tracker ? A solar tracker is a device that track of the sun. it follows the path of sun through out daytime with the help of sensors The sun position in the sky changes with the time and altitude angle and azimuth angle various continuously , Solar tracker are used for solar panels in solar power plants where energy generation is describable up to maximum limit 4/9/2019 4
- 5. TYPES OF SOLAR TRACKER Solar tracking system is classified by its degree of rotation. According to degrees of rotation trackers can be grouped in two primary categories. Single Axis Solar Tracker Dual Axis Solar Tracker 4/9/2019 5
- 6. Single Axis Tracker A single axis solar tracker follows the movements of sun either horizontally or vertically. This type of tracker has only one axis for rotation The horizontal type solar tracker is used in tropical regions where the sun gets very high at noon , but the day are short. On the other hand The vertically type solar tracker is used In areas with high altitude where the sun does not get very high , but summer days can be very long In concentrated solar power application single axis solar tracker are used with parabolic and linear fresnel mirror designs 4/9/2019 6
- 7. DUAL AXIS SOLAR TRACKER A dual axis solar tracker has two degrees of rotation . It can track sun both horizontal and vertical This type of solar tracker can be used any where in the world and achive maximum efficiency in gaining solar energy Concentrated solar power application using dual axis tracking is extremely important in solar power tower application Design for dual axis tracking system is complex than single axis tracking and operation is more energy consuming 4/9/2019 7

- 9. Need for a sun tracking system Global warming has increased the demand and request for green produced by renewal sources as solar power. Solar energy has been the power supply of choice for industrial application where power is required at remote location. Solar tracking is increases applied as a effective power generation. 4/9/2019 9
- 11. Condition for maximum output The difference between the incident ray and reflected ray should be equal to zero, i.e the ray should be perpendicular to each other The altitude is directly proportional to the efficiency of the system up to the certain limit Very clear sky and clean atmosphere contributes a bit more to the efficiency of the system. 4/9/2019 11

- 13. Working Of Solar Tracker There are two different driver that dictate the motion of the tracker :passive and active. Passive trackers depend solely on solar heat to guide and move the tracker . Active tracker used a controller that monitors the position of the sun movements in order to direct motors that’s moves the tracker In most solar trackers LDRs are used as sensor ,there different in output is generat error signal. In these system 4/9/2019 13
- 15. The Input The various positions of the sun over a year for a particular geographical location is given as the primary input to the microcontroller. The irradiance of the sun for a particular geographical location over a year is the input of microcontroller The real time clocking is enabled in the microcontroller 4/9/2019 15
- 16. Advantage Solar tracking system continually orient photovoltaic panels towards the sun and can maximize your investment in your pv system One time investment, which provided maximum efficiency and provided flexibility on dependency over other sources. Bulk implementation of tracking system help reduced consumption of power by other sources. Tracking system can help reducing emission and can contribute against warming It enhances the clean and emission free power production 4/9/2019 16
- 17. Disadvantage Initial investment is high on solar panel , motor and any other devices . Moving parts and gears which will require regular maintenance. May require or repair or replacement of broken parts over a long run. 4/9/2019 17
- 18. Application Can be used for small & medium scale power generation . For power generation at remote places where power lines are not assessable For domestic backup power system. 184/9/2019
- 19. Conclusion On one hand we can see the worlds energy resources depletion to be a major problem On the other hand global warming , which is major concern . Switching to solar power , which is clean and green and enchancing its efficiency by using sun tracker is a great option in the near future. 4/9/2019 19
