Photovoltaic Systems Installed at Chosun University in Korea

Recently, Photovoltaic system is spotlighted technology of environmental friendly energy- system in the worldwide. Because conventional methods of generating electricity (e.g. burning coal and other fossil fuels) produce pollutions such as carbon dioxide, the main gas responsible for global warming. Furthermore, fossil fuels and uranium are non-renewable resources. But the only resource needed to power a solar cell is sunlight. Solar energy is clean, quiet, abundant and a renewable energy source, which produces no pollution to the environment. With the growing concern over green-house gas emissions and other environmental issues, renewable energy sources are being increasingly adapted in many applications. Utility interconnected photovoltaic systems is one of the most promising applications of photovoltaic systems. A photovoltaic panel is a device that, through the photovoltaic effect, converts luminous energy into electric energy. This paper presents a utility interactive photovoltaic generation systems of 3kW, lOkW, 20kW and 50kW installed at Chosun University in Korea.
