This paper presents a study of the solar radiation data measured in Osmaniye (37.04 E, 36.22 N) during September 2022 - August 2023. Measurements were carried out using total six different solar Photovoltaic (PV) systems, which five oriented towards the south (=30°, 37°, 45°, 60° and 90°) and one towards the zenith direction (=0°). Data measured in minutes were analyzed hourly, daily, monthly, seasonally and annually in in W/m2. The monthly averages of daily total solar radiation measured at =0°, 30°, 37°, 45°, 60° and 90° directions were determined to be 327.92 W/m2, 400.05 W/m2, 406.20 W/m2, 401.37 W/m2, 374.80 W/m2 and 279.37 W/m2, respectively. The average annual solar energy measured in all directions ( =0°, 30°, 37°, 45°, 60° and 90°) was 310.99 W/m2, 355.93 W/m2, 359.23 W/m2, 351.60 W/m2, 317.57 W/m2, and 221.99 W/m2, respectively. When the daily, monthly and annual variations are examined, it is seen that higher solar energy is obtained from PV solar panels in the = 30°, 37° and 45° directions, which are close to the latitude angle of Osmaniye (37°.04). The results showed that the average solar radiation measured in the "=37°" direction was 0.93%, 2.17%, 13.12%, 15.51% and 61.82% higher than those measured in the =30°, 45°, 60°, 0° and 90° directions.

Osmaniye’de Güney Yönünde Altı Farklı Eğim Açısında (0°, 30°, 37°, 45°, 60° ve 90°) Fotovoltaik Kolektörler Kullanılarak Toplam Güneş Radyasyonun Ölçülmesi

Bu çalışma, Eylül 2022 - Ağustos 2023 döneminde Osmaniye’de (37°.04 D, 36°.22 K) ölçülen güneş radyasyonu verilerinin bir incelemesini sunmaktadır. Ölçümler, beşi güneye (=30°, 37°, 45°, 60° and 90°) ve biri başucu doğrultusuna (=0°) doğru yönlendirilmiş toplam altı farklı PV güneş sistemi kullanılarak gerçekleştirilmiştir. Dakikalık olarak ölçülen veriler in W/m2 biriminde saatlik, günlük, aylık, mevsimlik ve yıllık olarak analiz edilmiştir. =0°, 30°, 37°, 45°, 60° ve 90° yönlerinde ölçülen günlük toplam güneş ışınımının aylık ortalamaları sırasıyla 327.92 W/m2, 400.05 W/m2, 406.20 W/m2, 401.37 W/m2, 374.80 W/m2 ve 279.37 W/m2 olarak belirlenmiştir. Tüm yönlerde (=0°, 30°, 37°, 45°, 60° ve 90°) ölçülen yıllık ortalama güneş enerjisi sırasıyla 310.99 W/m2, 355.93 W/m2, 359.23 W/m2, 351.60 W/m2, 317.57 W/m2 ve 221.99 W/m2olduğunu görülmüştür. Günlük, aylık ve yıllık değişimleri incelendiğinde, Osmaniye’nin enlem açısına (37°.04) yakın olan =30°, 37° ve 45° yönlerindeki FV güneş panellerden daha yüksek güneş enerjisinin elde edildiği görülmektedir. Sonuçlar, "=37°" yönünde ölçülen ortalama güneş radyasyonunun, =30°, 45°, 60°, 0° ve 90° yönlerinde ölçülenlerden sırasıyla %0.93, %2.17, %13.12, %15.51 ve %61.82 daha yüksek olduğunu göstermiştir.
