EVALUATION OF EFFECTS OF ORIENTATION ANGLE AND MOUNTING POSITION OF PV MODULES IN ENERGY OUTPUT FOR DIFFERENT LONGITUDES

Abstract

This study focuses on influences of orientation angle and mounting position of PV modules on energy output for different longitudes in August. Analyses were carried out using L8 orthogonal array, which have three control factors with two levels, according to Taguchi technique. Orientation angle and mounting position of PV modules and longitude were considered as control factors. Effects and the optimum levels of control factors on PV energy output were evaluated using analysis of Signal-to-Noise (S/N) ratio whereas importance and percentage contribution rates of control factors on PV energy output were determined using analysis of variance (ANOVA) at 95 % confidence level. According to results, the optimum energy output was obtained using the second levels of PV orientation angle, PV modules mounting position, and longitudes. Also, PV orientation angle, PV mounting position, and longitudes are significant control factors due to P < 0.05 value. Also, the most effective control factors are found to be PV mounting position with 95.23 %, PV orientation angle with 2.98 %, and longitudes with 1.67 %, respectively.
