집광추적형 PV발전의 특성에 관한 연구

Photovoltaic Power Generation system occupies an important position as an alternative energy source, converting directly sunlight into electricity, using a photovoltaic cell.The Purpose of this research is to present and confirm the effectiveness of concentration and tracking of sun in photovoltaic power generation. Comparative experiments were carried out with two rating 75 watt solar modules in 25℃ under condition of various times concentration, tracking and plain normal measuring generated voltages, currents and temperatures of back sheet of modules by internet monitoring system to find out which is best in economic sense. The experiments show that output power of concentration and tracking photovoltaic power generation is over180% more then that of plain normal system.
