본 발명은 다수의 판상(板狀) 태양전지모듈(solar cell module)이 조합되어 구성되는 태양광 발전시설에 관한 것으로, 발전시설을 구성하는 각각의 태양전지모듈을 소정거리 이격하여 인접한 태양전지모듈 사이에 통기구를 형성하도록 설치하고 이들 통기구의 배후에 유도판을 설치함으로써, 태양전지모듈 전면의 기류가 통기구를 통과한 후 유도판에 의하여 태양전지모듈 배면측으로 유입되도록 하여 태양전지모듈의 전면 뿐 아니라 배면이 동시에 냉각될 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic power generation facility in which a plurality of plate-shaped solar cell modules are combined, and each solar cell module constituting the power generation facility is adjacent to each other by a predetermined distance. By installing vents between them and installing guide plates behind these vents, the airflow in front of the solar cell module passes through the vents and flows into the solar cell backside by the guide plate.

화석연료의 고갈 및 환경오염 문제로 인하여 자연상태에서 만들어진 청정 에너지인 신재생에너지에 대한 관심 및 수요가 증가하고 있다.Due to the depletion of fossil fuels and environmental pollution, there is a growing interest and demand for renewable energy, which is a clean energy made in the natural state.

태양에너지는 대표적인 신재생에너지로서, 태양전지를 이용한 태양광 발전의 경우 대용량 및 소용량의 발전 모두에 적합한 특성이 있을 뿐 아니라, 설치 및 유지관리가 용이한 장점이 있어, 다양한 분야에 적용되고 있다.Solar energy is a typical renewable energy, and in the case of photovoltaic power generation using solar cells, the solar energy is not only suitable for both large capacity and small capacity power generation, but also has an advantage of easy installation and maintenance.

태양광 발전시설을 구성하는 태양전지는 일종의 광전소자(光電素子)로서, 온도가 상승함에 따라 발전효율이 저하되는 특성을 가진다.The solar cell constituting the photovoltaic power generation facility is a kind of photoelectric device, and has a characteristic of decreasing power generation efficiency as the temperature increases.

따라서, 태양광 발전시설의 설치에 있어서 설치지점의 태양광 입사량 및 입사각 뿐 아니라 풍향 또한 고려하여 설치위치 및 설치각도를 결정하게 되는데, 통상 태양광 발전시설의 전면이 바람이 불어오는 쪽을 향하도록 설치함으로써, 바람에 의하여 태양전지모듈의 전면(前面)이 냉각될 수 있도록 설치하는 것이 일반적이다.Therefore, in the installation of the photovoltaic power generation facility, the installation location and the installation angle are determined in consideration of the wind incidence as well as the amount of incidence and the incident angle of the installation point. It is generally installed to allow the front surface of the solar cell module to be cooled by wind.

태양전지모듈이 태양광을 수광하여 발전을 개시하면, 발전과정에서 태양전지모듈에 열이 발생될 뿐 아니라, 태양의 복사에너지에 의하여 태양전지모듈의 온도가 상승하게 되는데, 이는 태양전지모듈의 발전효율 저하로 이어진다.When the solar cell module starts to generate power by receiving sunlight, not only heat is generated in the solar cell module during the power generation process, but also the temperature of the solar cell module is increased by the radiant energy of the sun. Leads to a decrease in efficiency.

종래의 자연 풍냉식 태양광 발전시설의 경우, 태양전지모듈 전면(前面)의 냉각에만 역점을 두고 있는 바, 사실상 태양전지모듈 배면의 직접 냉각효과는 기대할 수 없었다.In the conventional natural air-cooled photovoltaic power generation facilities, the emphasis is only on the cooling of the front surface of the solar cell module, and in fact, the direct cooling effect on the rear of the solar cell module could not be expected.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 다수의 판상(板狀) 태양전지모듈(solar cell module)(10)이 조합되어 구성되는 태양광 발전시설에 있어서, 각 태양전지모듈(10)은 소정거리 이격되어 인접한 태양전지모듈(10) 사이에 통기구(11)를 형성하도록 설치되고, 통기구(11)의 배후에는 통기구(11)의 폭보다 넓은 폭을 가지는 유도판(20)이 태양전지모듈(10)의 배면에서 소정거리 이격되도록 설치됨을 특징으로 하는 배면 풍냉식 고효율 신재생에너지 태양광 발전시설이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and each solar cell module (10) in a solar power generation facility comprising a plurality of solar cell module (10) in combination. Is installed to form a vent 11 between adjacent solar cell modules 10 spaced apart by a predetermined distance, and the induction plate 20 having a width larger than the width of the vent 11 is provided behind the vent 11. It is a rear wind-cooled high efficiency new renewable energy photovoltaic power generation facilities, characterized in that the rear space of the module 10 is installed to be spaced apart.

또한, 상기 유도판(20)에는 중심부에서 양 측단부 방향의 경사가 대칭으로 형성되어, 유도판(20)의 중심부보다 양 측단부가 태양전지모듈(10)의 배면에 근접하도록 설치됨을 특징으로 하는 배면 풍냉식 고효율 신재생에너지 태양광 발전시설이다.In addition, the induction plate 20 is inclined in both directions of the side end portion in the center is formed symmetrically, characterized in that both side ends than the center of the guide plate 20 is installed so as to be closer to the back surface of the solar cell module 10. It is a rear wind-cooled high efficiency renewable energy photovoltaic power generation facility.

본 발명을 통하여 태양광 발전시설의 냉각효과를 향상시킬 수 있으며, 이로써 각 태양전지모듈의 발전효율을 제고하여, 태양광 발전시설의 전력생산성 및 경제성을 확보함으로써 무공해 청정에너지인 태양광 발전의 보급을 확대하는 효과를 얻을 수 있다.Through the present invention, it is possible to improve the cooling effect of the photovoltaic power generation facilities, thereby improving the power generation efficiency of each solar cell module, and to secure the power productivity and economic efficiency of the photovoltaic power generation facilities to disseminate solar power generation of clean energy. The effect of enlarging can be obtained.
