Özet:

 PV systems are very important to ensure the efficient operation of photovoltaic PV systems in electricity generation. However, environmental conditions or degradation of the panels affect this production. In this paper, in order to investigate the factors affecting the efficiency, the surface temperature under full irradiation and partial shading conditions is measured with a thermal camera and analyses are performed. According to pollution levels, the panels are classified as defective and healthy in two different conditions and characteristic curves of PV panels are generated. According to the experimental results, it is observed that in both full irradiation and partial shading conditions, the clean panel washed with water produces more power than the other panels and the surface temperatures are at the optimum level. This study shows that regular cleaning of PV panels and detection of panel defects by thermal imaging camera are beneficial to increase the efficiency.

 Elektrik üretiminde fotovoltaik PV sistemlerin verimli çalışmasını sağlamak çok önemlidir. Ancak çevresel koşullar veya panellerin bozulması bu üretimi etkilemektedir. Bu makalede, verimliliği etkileyen faktörleri incelemek için tam ışınım ve kısmi gölgelenme koşulları altında yüzey sıcaklığı da termal kamera ile ölçülerek analizler gerçekleştirilmiştir. Farklı kirlilik seviyelerine göre paneller iki farklı koşulda arızalı ve sağlıklı olarak sınıflandırılarak PV panellerin karakteristik eğrileri oluşturulmuştur. Deneysel sonuçlara göre hem tam ışınım hem de kısmi gölgeleme koşullarında su ile yıkanmış temiz panelin diğer panellere göre daha fazla güç ürettiği ve yüzey sıcaklıklarının optimum seviyede olduğu gözlemlenmiştir. Bu çalışma, PV panellerin düzenli olarak temizlenmesi ve panel kusurlarının termal kamera ile tespit edilmesinin verimliliği arttırmak için faydalı olduğunu göstermektedir.
