Solar Energy

  1. 1. Solar Energy Solar energy, here today, here tomorrow
  2. 2. Solar Energy <ul><li>What is solar energy? </li></ul>
  3. 3. Solar Energy <ul><li>Sunlight is composed of photons, or particles of energy. </li></ul><ul><li>These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. </li></ul><ul><li>We use this energy directly and indirectly. </li></ul>
  4. 4. Solar Energy <ul><li>Direct – </li></ul><ul><li>Indirect – </li></ul>The photons are absorbed by a surface, creating heat or electricity. The heat produce could be changed into steam energy to do work (steam turbines).
  5. 5. Solar Energy <ul><li>When was solar energy first used to do work? </li></ul>In 1860, Auguste Mouchout, used direct conversion of solar radiation into mechanical power.
  6. 6. Solar Energy <ul><li>Mouchout's Solar collector. </li></ul>
  7. 7. Solar Energy <ul><li>Other prominent inventors include: </li></ul><ul><li>William Adams </li></ul><ul><li>Charles Tellier </li></ul><ul><li>John Ericsson </li></ul><ul><li>Aubrey Eneas </li></ul><ul><li>Henry E. Willsie </li></ul><ul><li>Frank Shuman </li></ul>
  8. 8. Solar Energy <ul><ul><li>All of the inventions produce gas under pressure, like steam, to do work. </li></ul></ul><ul><ul><li>The work that we are most interested in, </li></ul></ul><ul><ul><li>is the generation of electricity. </li></ul></ul>
  9. 9. Solar Energy <ul><li>Parabolic Trough </li></ul>
  10. 10. Solar Energy <ul><li>Solar Tower </li></ul>
  11. 11. Solar Energy <ul><li>Heliostats </li></ul>
  12. 12. Solar Energy <ul><li>Solar Tower </li></ul><ul><li>http://www.enviromission.com.au/project/video/video.htm </li></ul>
  13. 13. Solar Energy <ul><li>Photovoltaic Cells – PV cells </li></ul><ul><li>Photovoltaic energy is the conversion of sunlight into electricity through a photovoltaic (PV) cell, commonly called a solar cell. </li></ul><ul><li>This is the photoelectric effect. </li></ul>
  14. 14. Solar Energy <ul><li>PV cells are commonly made from silicone. </li></ul><ul><li>CIGS (Copper Indium Gallium Diselenide) and CdTe (Cadmium Telluride) solar cell materials </li></ul>
  15. 15. Solar Energy <ul><li>President Bush on tour. </li></ul><ul><li>http://mfile.akamai.com/5913/wmv/whitehouse.download.akamai.com/5913/2006/02/20060220-2.v.asx </li></ul>
  16. 16. Solar Energy <ul><li>From the discovery of the photoelectric effect in 1839, to the first module in 1954, the efficiency continues to increase. </li></ul><ul><li>The industry efficiency has grown from 3-6% to 33% and beyond. </li></ul><ul><li>NASA uses arrays that are 40% efficient. </li></ul>
  17. 17. Solar Energy <ul><li>Multiple Exciton Generation Process </li></ul><ul><li>N anotechnology </li></ul><ul><li>Quantum dots </li></ul>Researchers are predicting 65% efficiency.
  18. 18. Solar Energy <ul><li>Spray-On Solar-Power </li></ul>Again, nanotechnology is being used to produce a composite that can be sprayed onto other materials.
  19. 19. Solar Energy <ul><li>Members of the International Solar Agency </li></ul><ul><li>Australia Austria Belgium </li></ul><ul><li>Canada Denmark Finland </li></ul><ul><li>France Germany Italy </li></ul><ul><li>Mexico Netherlands New Zealand </li></ul><ul><li>Norway Portugal Spain </li></ul><ul><li>Sweden Switzerland USA </li></ul>
  20. 20. Solar Energy Solar Energy <ul><li>Solar PV Use Is Growing Rapidly </li></ul><ul><li>• 2006: 5,600 MW Worldwide </li></ul><ul><li>• $20+ Billion </li></ul><ul><li>• Major Markets </li></ul><ul><ul><ul><li>Germany 750+ MW/yr </li></ul></ul></ul><ul><ul><ul><li>Japan 350 MW/yr </li></ul></ul></ul><ul><ul><ul><li>Spain 25 MW/yr? </li></ul></ul></ul><ul><ul><ul><li>California 50-75 MW/yr </li></ul></ul></ul>
  21. 21. Solar Energy <ul><li>Off Grid </li></ul><ul><li>Grid Connected </li></ul><ul><li>Grid Connected Distributed </li></ul><ul><li>Grid Connected Centralized </li></ul>
  22. 22. Solar Energy
  23. 23. Solar Energy
  24. 24. Solar Energy
  25. 25. Solar Energy
  26. 26. Solar Energy <ul><li>Not all the countries that have a solar implementation plan, are on the same footing. Some are doing better then others. </li></ul><ul><li>Governments are providing large sums of money for incentives, R&D, and to help create receptive markets. </li></ul>
  27. 27. Solar Energy <ul><li>The success or failure of these plans depend on many factors. </li></ul>Cost Efficiency Available Technologies Government Support Public Perception
  28. 28. Solar Energy <ul><li>The problem with solar power has never been its appeal. It has just cost too much. </li></ul><ul><li>This concludes the solar energy presentation. </li></ul><ul><li>Thank You! </li></ul>
