Concentrated solar power2

  1. 1. SOLAR THERMAL ENERGY C.KARUN KUMAR Swarnandhra Engineering College
  2. 2. INTRODUCTION• Solar energy is most efficient , harmless and renewable energy source• Solar energy is very economical• Solar energy is available everywhere
  3. 3. BACKDROPS OF SOLAR ENERGY• Involves high initial costs• Unavailability at all times
  4. 4. CSP• CSP stands for Concentrated Solar Power• Concentrated Solar Power (CSP) is a process of concentrating heat in one point
  5. 5. HELIOSTAT• A Heliostat (from Helios, the Greek word for sun, and stat, as in stationary)• Heliostat is a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target
  6. 6. • Reflective surface of mirror is kept perpendicular to the bisector of the angle between the directions of the sun and target
  7. 7. GEMASOLAR POWER PLANT• Installed capacity – 20 MW• Annual generation – 110 GWh• Heliostats – 2,650
  8. 8. WORKING• The concentrated solar power used to heat fluid deposit• Working fluid is heated upto 250–1000°C• This fluid is used to run steam turbine
  9. 9. TYPES OF SOLAR CONCENTRATERS• Heliostats• Parabolic trough collectors• Stirling dish• Fresnal concentrator
  10. 10. PARABOLIC TROUGH COLLECTORS
  11. 11. STIRLING DISH
  12. 12. FRESNAL CONCENTRATOR
  13. 13. ADVANTAGES OF STP• Capable of supplying power continuously• High potential under the Renewable energy sources• Solar collectors absorb the energy from the sun 3- 4 times more efficiently than solar cells.• The price of solar collectors is about 3 times less than the price of solar cells.• A solar collector also generates energy on cloudy days
