Performance Results and Analysis of Large Scale PV System

This paper presents performance result and analysis of large scale photovoltaic system (PV) supported by general dissemination & regional energy program in government polices for renewable energy sources in Korea. The total nominal capacity of PV systems installed at sincheon sewage disposal plant (SSDP) in Daegu City is 479 kW. The one of those, to evaluate and analyze performance of early installed 80 kW PV system, PV monitoring system is constructed and monitored performance results of PV system to observe the overall effect of environmental conditions on their operation characteristics. The PV system performance has been evaluated and analyzed for component perspective (PV array and power conditioning unit) and global perspective (system efficiency, capacity factor, and electrical power energy and power quality etc.) for six month monitoring periods
