Abstract

The solar radiation incident on the surface of photovoltaic (PV) panels, dependent on the inclination
angle, and the temperature of the panels are the most significant parameters affecting power
generation. These two parameters are necessary to accurately evaluate the electrical performance by
enabling the calculation of cell and module temperatures. In this study, the efficiencies and electrical
power behaviors of PV panels positioned towards the sun at a 37° inclination angle in Hakkari province
were examined under real solar radiation and ambient temperature values. In addition, the effect of
wind speed parameters was also considered, and the impact on panel efficiency and PV panel output
power was evaluated. When the results were evaluated, it was confirmed that the effect of wind
increases the efficiency of PV panels, resulting in an increasing in PV output power.

Anlık Güneş Işınımı ve Meteorolojik Parametrelere Bağlı Olarak Fotovoltaik Panel Güç Üretiminin Değerlendirilmesi

Abstract

Fotovoltaik (PV) panel yüzeyine eğim açısına bağlı olarak düşen güneş ışınımı ve panellerin sıcaklığı güç
üretimini etkileyen en önemli parametrelerdir. Bu iki parametre hücre ve modül sıcaklık
hesaplamalarının yapılmasını sağlayarak elektrik performansını doğru bir şekilde değerlendirmek için
gereklidir. Bu çalışmada, Hakkâri ilinde 37° eğim açısı ile güneşe doğru konumlandırılmış PV panellerin
gerçek güneş ışınımı ve ortam sıcaklığı değerleri altındaki verimleri ve elektriksel güç davranışları
incelenmiştir. Bunun yanı sıra, rüzgâr hızı parametresinin etkisi de dikkate alınarak panel verimleri ve
PV panel çıkış gücü üzerindeki etkisi değerlendirilmiştir. Sonuçlar değerlendirildiğinde, rüzgârın etkisinin
PV panellerin verimlerini yükselttiği ve buna bağlı olarak PV çıkış gücünün arttığı doğrulanmıştır.
