INVESTIGATION OF PEAK POWER AND TECHNOLOGY OF PHOTOVOLTAIC IN ENERGY OUTPUT ACCORDING TO SYSTEM LOSS

Abstract

The aim of this study is to evaluate the effects of peak power and technology of photovoltaic (PV) in energy output from fix-angle PV system according to system loss. The maximum efficiency tests were conducted using L8 orthogonal array with three control factors including two levels based on Taguchi method. Control factors consist of Peak PV power, PV technology, and system loss. In order to organize the optimum levels and effects of the control factors in the energy output, signal-to-noise (S/N) ratio analysis was implemented. The most effective control factors in the energy output were found by analysis of variance (ANOVA). According to results obtained, , the most control factors in energy output were detected as peak PV power with 65.60 % contribution, PV technology with 19.37 % contribution, and system loss with 14.94 % contribution, respectively. The increase of levels of peak PV power and PV technology leads to the increase of energy output data while increase of level of system loss causes the decrease of energy output.
