  3. 3. A solar tracker is a generic term used to describe devices that orient or align various payloads toward the sun. Example for payloads are photovoltaic panels, reflectors, Collectors, lenses or other optical devices. The system focuses on the optimization of the electric energy produced by photovoltaic cells through the development of a sun-tracking system. SOLAR TRACKER
  4. 4. AIM OF THE PROJECT To follow the sun from dawn, throughout the day, till evening and again from dawn next day. The driver will have to position a photo-voltaic panel to the best angle of exposure to sunlight for collection of maximum solar energy.

  10. 10. ULN2003  ULN is Relay driver application.  The ULN2003 is a high voltage and high current Darlington transistor arrays.  It consists of seven NPN Darlington pairs that features high-voltage output with common- cathode clamp diode for switching inductive loads.  The collector-current rating of a single Darlington pair is 500mA.  The Darlington pairs may be paralleled for higher current capability.
  11. 11. ADVANTAGES Solar tracking systems continually orient photovoltaic panels towards the sun and can help maximize your investment in your PV system. One time investment, which provides higher efficiency & flexibility on dependency over other sources. Tracking systems can help reducing emissions and can contribute against global warming. Bulk implementations of tracking systems help reduced consumption of power by other sources. It enhances the clean and emission free power production.
  12. 12. DISADVANTAGES Initial investment is high on solar panels. It’s a bit of difficult for servicing, as the tracking systems are not quite popular regionally. Moving parts and gears which will require regular maintenance. May require repair or replacement of broken parts over a long run.
  13. 13. APPLICATIONS Can be used for small & medium scale power generations. For power generation at remote places where power lines are not accessible. For domestic backup power systems.
