3㎾ 태양광발전시스템의 효율분석에 관한 연구

Utility interactive photovoltaic systems is one of the most promising applications of photovoltaic systems. These systems are employed in applications where utility service is already available. In this case, there is no need for battery storage because utility power may be used to supplement photovoltaic systems when the load exceeds available PV generation. The load receives electricity from both the photovoltaic array and the utility inter-tied. In this paper, Principle and operating characteristic of Utility Interconnected Photovoltaic System is presented. For the purpose of optimal utility inter-tied photovoltaic system design and installation. It is that demonstrate throughout the installed 3 PV system respectively, 3 ㎾ utility interconnected residential system.
