Özet:

 

Turkey is becoming more dependent on imported primary energy  to meet its increasing energy demand.  The ratio of indigenous primary  energy production to primary energy consumption is decreasing  noticeably.  Therefore, it is of great importance for Turkey to make  use of its indigenous energy resources more effectively, including its  solar energy potential.  Solar energy is one of the most abundant  energy resources in the country and should be utilized at the maximum  level possible.  The global solar radiation incident on a horizontal  surface and daily sunshine hours are measured in Turkey by many  recording stations of the Turkish State Meteorological Service (DME).   According to these measurements, the yearly average daily solar  radiation was 3.6 kWh/m2, with a yearly total radiation period of  over 2640 h.  However, in recent years it has widely been acknowledged  that the actual solar energy potential of Turkey is more than was  previously thought.    In the present article, the solar radiation data on Ankara (lat 39.95  °N, long 32.88 °E; elevation: 891 m) are analyzed based on 6 years of  global solar radiation data measured on a horizontal surface by the  DME. The distributional solar radiation parameters are derived from  the available data and analyzed.  The available solar radiation data  on a horizontal surface are converted to that of various tilt angles  and the yearly and monthly optimum tilt angles are determined.
