More Information
Summary:An objective of the present invention is to provide a photovoltaic power generation system which can minimize the effect of temperature between solar cells while the solar cells are separated only by minimum spaces in a solar cell panel to be arranged, and efficiently cool the solar cells included in the solar cell panel to prevent degradation of the photoelectric conversion efficiency and life of the solar cells. The photovoltaic power generation system comprises a solar cell panel, a storage battery, a cooling device, a temperature measurement device, and a controller. The solar cell panel includes first to n^th solar cell strings each consisting of two or more solar cells. The storage battery stores power generated by the solar cell panel. The cooling device cools the solar cell panel. The temperature measurement device measures the temperature of the solar cell panel. The controller divides the first to n^th solar cell strings into first to m^th photoelectric conversion groups each consisting of nonadjacent solar cell strings which are not adjacent to each other, and determines the operating status of the first to m^th photoelectric conversion groups based on the temperature of the solar cell panel. 태양광 발전 시스템은 태양 전지 패널, 축전지, 냉각 장치, 온도 측정 장치 및 컨트롤러를 포함한다. 태양 전지 패널은 2개 이상의 태양 전지들로 각각 구성된 제1 내지 제n 태양 전지 스트링들을 포함한다. 축전지는 태양 전지 패널에서 생성된 전력을 저장한다. 냉각 장치는 태양 전지 패널을 냉각시킨다. 온도 측정 장치는 태양 전지 패널의 온도를 측정한다. 컨트롤러는 제1 내지 제n 태양 전지 스트링들을 서로 인접하지 않는 비인접 태양 전지 스트링들로 각각 구성된 제1 내지 제m 광전 변환 그룹들로 구분하고, 태양 전지 패널의 온도에 기초하여 제1 내지 제m 광전 변환 그룹들 각각의 동작 여부를 결정한다.
