• SOLAR ENERGY
• Solar energy has several advantages as
  compared to other RES.

  – Solar energy is plenty and endless.
  – It has no waste product.
  – It is possible to use solar energy whereever
   required.
                                             This project is funded by the European Union




  materials, methods and technologies used in the
  solar energy applications:
• Thermal Solar Technologies :
  Heat produced from solar energy in these systems
  can be used directly as well as for electricity
  production.
• Solar Cells:
  These materials, which can be classified as semi-
  conductors and called as photovoltaic cells change
  solar radiation to electricity directly.
                                                  This project is funded by the European Union




• Thermal Solar Energy Technologies
• Solar energy applications can be divided into two as
  heat and electricity production.
• Heat production can be classified into low, medium
  and high heat applications.

   – Low heat application, flat plate collectors
   – Medium heat application, systems that make linear
    condensation (parabolic trough systems)
   – High heat application, sytems that make point
      condensation (parabolic dish and centeral type)
                                              This project is funded by the European Union




• Solar Collectors
• Flat plate solar collectors can be thougth as major
  and widespread usage area for solar energy
  applications.
• Plate type solar collectors are used widely in Turkey
  for the purpose of hot water production.
• These systems can heat the liquid inside up to
  80°C.
• Besides hot water requirements of buildings, they
  can be used for supplying hot water to swimming
  pools and industrial facilities.
                                              This project is funded by the European Union




• According to data in 2003, total solar collector
  (with or without glass+ with air), constructed
  in the world, is about 150 million m2.
                                      m2
   –The country having the most number of solar
    collectors is USA with 30 million m2.
   –The second is Japan with 12,5 million m2 .
   –The third one is Turkey with 11 million (8 million
    in 2003) m2.

• On the basis of survey results conducted by EİE for
  production companies and State Institute of Statistics (SIS)
  for consumers;

   – Turkey utilizes 11 million m² solar collectors in 2006 and this value
     increases by 700 000-1 million m² in each year.
   – Producer solar collector companies are about 50.
   – Solar energy production is equivalent to 400 000 TOE in 2006.
   – Considering these figures, Turkey is the one of the leader country in
     the world,
   – however,
     however
   – in the case of solar collector area per capita
   – (0.14 m²/capita), there exist countries being in the better situation than
     Turkey.
                                          This project is funded by the European Union




• Currently, solar collectors are used in Agean
  and Mediterrenian regions of Turkey in
  residential buildings and touristics facilities.
• However, there is a great potential of solar
  energy in the other regions of Turkey as well.
• In this respect, utilization of SWH is expected
  to increase in the South East region of Turkey
  which is currently very low.
                                              This project is funded by the European Union




• Thermal Solar Energy Plants
• The second biggest group in the application of
  thermal solar energy is plants used for production of
  electricity.
• They can be either parabolic channel, parabolic
  bowl or centered reciever collector types.
• These kind of systems can reach higher
  temperatures as they can make condensation.
• Plants with parabolic channel type collectors was
  entered in the commercial market, the most famous
  and the biggest one of these plants is USA LUZ
  International with 350 MW power.
                                        This project is funded by the European Union




• Solar Cell Applications in Turkey:
• It is known that there exist solar cells with
  about 500 kW capacity in;
• forest observation towers of Ministry of
  Environment and Forestry,
• transmission stations of Turk Telekom,
• highway emergency phones and traffic signs,
• demonstration applications of EİE,
• various research institutes.
                                       This project is funded by the European Union




• In recent years, there is a tendency in the
  world to use PV systems connected to the
  network.
• EİE constructed solar cell systems connected
  to the network in Ankara having an
  installed capacity of 5 kW .
• Daily produced energy in Ankara is 15 kWh
                                             This project is funded by the European Union




• Cost Comparison
• The initial cost of solar cells is high. The cost of
  these cells is about 4-5 $/W
• Unit energy cost of them is changing about 25-
  40 cent/kWh.
     cent/kWh
• It can be economical in the places where
  photovoltaic electric network does not reach.
• Solar Water Heaters are cost effective
  compared to other fuels.
