집광추적형 PV발전 시스템의 설계에 관한 연구

Abstract

Photovoltaic Power Generation system occupies an important position as an alternative energy source, converting directly sunlight into electricity using photovoltaic cells.

The overall objective of this study is to present and confirm the effectiveness of a concentrating and tracking photovoltaic power generation. For this, comparative experiments were carried out with two rating 75 watt solar modules in 25℃ under different rate of a concentrating and tracking system and a normally fixed system as measuring generated voltages, current and temperature of back sheet of modules by a internet monitoring system to find out which is better in economic sense. The experiments show that the output power of the concentrating and tracking photovoltaic power generation is over 180% more than that of the fixed system and concentrating ratio which the system can be operated without a cooling system.
