碩士 === 健行科技大學 === 電機工程系碩士班 === 106 === This paper aims to investigate the actual power generation of two high-efficiency photovoltaic systems built on the top floor of the Chien Hsin University of Science and Technology college of electrical engineering and computer science by monitoring data and simulation software analysis. The modules adopt high-efficiency Passivated Emitter Rear Contact Solar Cell(PERC) technology and Heterojunction with Intrinsic Thin Layer Solar Cell(HJT) technology and the photovoltaic power generation system capacity is 1.55kWp, respectively. Analyze and compare the power generation performance and power generation efficiency of the two systems in the same irradiation environment, and make a detailed analysis and discussion on the characteristics of the two solar modules technologies. In this paper, PVsyst software package is used to analyze the power generation, economic cost, power generation system performance and the shading model of passivated emitter back contact solar module array and heterojunction intrinsic thin solar module array. To more accurately simulate the actual power generation situation and compare the simulation results with the actual monitoring data. According to statistics, the total power generation of HJT photovoltaic power generation system is 5.37% more than that of PERC photovoltaic power generation system in one year. The HJT and PERC photovoltaic power generation systems have their own advantages and disadvantages under high and low irradiation condition. The results of this study can be used as a reference for photovoltaic system setup and performance evaluation.
