Smart energy harvesing by solar tracking system

  1. 1. SMART ENERGY HARVESTING BY SOLAR TRACKING SYSTEM PRESENTED BY: GURUSHA NAHAR STUDENT (GITS)
  2. 2.  INTRODUCTION  WHY SOLAR ENERGY?  HIGHLIGHTED FEATURES OF SOLAR ENERGY  SOLAR CELL, ITS TYPE  SOLAR TRACKING SYSTEM FOR MAXIMUM POWER  WORKING OF PROTOTYPE  APPLICATION  FUTURE SCOPE AND CONCLUSION  REFERENCE OUTLINE
  3. 3. INTRODUCTION Energy is the biggest issue of this era that is causing the most controversial concern. Fossil fuel resources are limited and using them is known to cause global warming. Alternative options such as using renewable energy sources. Energy harvesting is the capture and conversion of small amounts of readily available energy in the environment into usable electrical energy. cont…
  4. 4. Hence, harvesting energy from nonconventional sources in the environment has received increased interest over the past few years. This paper concludes with the use of Smart energy harvesting device i.e.; SOLAR TRACKING SYSTEM.
  5. 5. Available in abundance It’s clean It’s infinitely renewable It can reduce your utility costs It increases self-reliance energy It comes with incentives Low maintenance and cost It’s extremely reliable ?
  6. 6. HOW CAN WE MOST EFFECTIVELY CAPTURE, CONVERT AND STORE THIS TREMENDOUS NATURAL RESOURCE? Solar cells are used for the mentioned purpose. Solar cells also known as Solar Photovoltaic cells or Photoelectric cells. These cells convert the solar radiation into D.C electricity ,which can be either used as it is or stored in the battery for use at night.
  7. 7. TYPES OF SOLAR CELLS
  8. 8. INTRODUCTION TO SOLAR TRACKING SYSTEM  Solar panel indeed provide sufficient energy to store, which is maximum 24.5% efficient.  Stationary panels used, are capable of getting maximum input source only when sun is on the head.  The alternative approach for providing better efficiency and rotation according to sun’s positioning led to the designing of tracking system.
  9. 9. What is solar tracking system?  A solar tracker is a device used for orienting solar panel or for concentrating solar reflector or lens toward the sun by using solar or light sensors connected with the machine (ex: stepper motor, servo motor, etc).  Hence, the sun tracking system collects more energy than what a fixed panel system collects increasing efficiencies up to 40-60%.  These devices change their orientation throughout the day to follow the sun’s path to maximize energy capture to the full extent.
  10. 10. COMPONENTS  Light dependent resistor (LDR)  Microcontroller  Motor (servo, stepper, etc)  Display unit (optional)  Solar panel
  11. 11. THE WORKING  Interfacing between hardware and microcontroller  Inputs to microcontroller  Controlling constraints

  14. 14. 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.
  15. 15. CONCLUSION AND FUTURE SCOPE  Automatic solar tracking system offers a prototype for implementing a large array type solar tracker.  It has been proven that solar tracking system with single axis freedom can increase energy output by approximately 40%. Further mechanical enhancement can be done to the prototype, to implement dual axis tracker.  Larger solar panel must be integrated with the system to prepare better result, cost analysis and use of renewable energy to cope up with the demand.
