Adana is located in a very suitable area due to solar energy (Long=35o 18 'E, Lat=36o 59' N, Alt=130 m). Due to the fact that the atmospheric conditions are not always constant for the investments to be made in the region, there is a need for regular measurements of solar energy and meteorological measurements.
In this study, instant data obtained with pyranometer in Cukurova University Space Sciences and Solar Energy Application and Research Center (UZAYMER) were analyzed with the program prepared with FORTRAN 77 program language. Hourly and daily data sets are created from data taken in seconds. Monthly, yearly and percentile radiation values are calculated from these data sets. With the nonatmospheric radiation energy values, the clearness values of Adana were obtained from the daily data.
The study consisted of two parts. The first part is the analysis of the data taken between 1978-1982 and the second is the analysis of the data taken in 2017 for comparison. Between the years of 1978-1982 in Adana, the average annual solar energy value was 5745,1 MJ/m2 and the average daily total radiation was 15.74 MJ/m2-day. The minimum energy is 6.84 MJ/m2-day in January and the maximum solar energy is 25.42 MJ /m2-day in June. As a result of the data obtained in 2017, the average annual solar energy is 17.75 MJ/m2-day and the annual average solar energy is 6479.99 MJ/m2. Maximum solar energy is 29.25 MJ/m2-day with July and at least 6.24 MJ/m2-day in December.
In addition, in the study, the statistics of 1978-1982 and 2017 were determined and compared. According to this result, for the value of Kt <0.34, it was assumed that the region was cloudy, Kt value 0.34≤ Kt≤ 0.64 between the partially cloudy and Kt> 0.64 value for the air is assumed to be open. The most cloudy month for the period 1978-1982 is February and the most open month is September. According to 2017 data, the most cloudy month is February and the clearest month is July and October. These values are guiding for the investments to be made.
