Solar tracking system

  1. 1. N.Cibiraj D.Shanmugakani S.Surulirajan
  2. 2.  Solar (or photovoltaic) cells convert the sun’s energy into electricity.  When photons strike a PV cell, they may be reflected or absorbed, or they may pass right through.  Only the absorbed photons generate electricity.
  3. 3.  A solar cell is a solidstate electrical device (p-n junction) that converts the energy of light directly into electricity (DC) using the photovoltaic effect.
  4. 4. RTC Geared motor Driver +5 V Battery Controller Solar Panel Mechanical arrangement LCD Display
  5. 5.  Totally nonvolatile with over 10 years of operation in the absence of power  Self–contained subsystem includes lithium, quartz, and support circuitry  Counts seconds, minutes, hours, days, day of the week, date, month, and year with leap year compensation valid up to 2100  Binary or BCD representation of time, calendar, and alarm  12– or 24–hour clock with AM and PM in 12–hour mode  Daylight Savings Time option
  6. 6.  Motor's position can then be commanded to move and hold at one of these steps without any feedback sensor.
  7. 7. Applications  Street light applications with out using normal power supplies.  In Remote areas implementing a small power systems units at each home.  Using this system to getting hot water
  8. 8. Advantages  The advantage of this unit is that to run the system it does not need computer.  Solar cells directly convert the solar radiation into electricity using photovoltaic effect without going through a thermal process.  During the winter the sun has a low position, tracking angle from sunrise to sunset is shortened.
  9. 9. Limitations  Using this system at a time we can control only one solar panel.  Higher hardware expenditure.  Weather condition can affect the system.
  10. 10. Future Scope  By Using controller microcontroller we can implement the intelligent system in future.  In Future the conventional energy is not sufficient for use so there is need of use non conventional energy sources
