Solar City Daegu Project(SCDP) represents a comprehensive model for shaping the future of Daegu city of 2.5 million residents with a mixed industrial and services economic base. Its specific aims are as follow: realization of a carbon footprint consistent with standards of global sustainability and equity; the development of renewable energy based urban community and economy; and the pursuit of economic development that meets the needs of Daegu's citizens in a manner that is culturally and ecologically sound. We evaluated specifically the photovoltaic(PV) systems among various concrete SCDP. We conducted the economic-environmental analysis for 8 separate PV systems which have been connected to the monitoring system at the Research Institute for Energy, Environment and Economy, and accumulated real generation data on web-based database system. We show that the economics of the PV projects can be improved if 70% of the investment would be charged by the system owners and the full cost rate(for the below 30kW, 711.25 won/kWh; for the above 30kW, 677.38 won/kWh) would be warranted for the life span of the system. And it is suggested that the environmental impacts such as greenhouse gas reductions be considered in the economic analysis of PV systems.
