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.}, number={2}, publisher={Çukurova Üniversitesi}, organization={Mersin University}
