태양전지가 가장 효율적으로 발전이 되는 때는 면에 수직으로 태양광선이 입사될 때임을 감안하여, 동일한 모양과 사양을 가진 태양전지들을 반구형의 형태로 배열시킴으로써, 햇빛이 언제 어디서 비취더라도 가장 성능이 좋은 전지를 선출할 수 있게 한다. 선택된 전지의 표면에 수직으로 햇빛이 입사된다고 판단할 수 있다.Considering that solar cells are the most efficient power generation when the solar light is incident perpendicularly to the plane, the solar cells having the same shape and specifications are arranged in a hemispherical shape, so that the best performance is possible even when the sunlight shines. Allow the battery to be elected. It may be determined that sunlight is incident perpendicularly to the surface of the selected cell.

태양전지들을 반구형의 형태로 배열시킴으로써, 즉 태양전지의 기울기가 상하좌우 전 방향으로 배치되므로 햇빛을 이용하는 기기의 기울기는 상하좌우 전 방향으로 태양전지의 기울기를 따를 수 있게 한다.By arranging the solar cells in a hemispherical form, that is, since the inclination of the solar cells is arranged in all directions up, down, left and right, the inclination of the device using sunlight enables the solar cells to follow the inclination of the solar cells in all directions.

햇빛의 조사각도를 전기신호로 변환한 정보를 보내면 햇빛을 이용하는 기기를 최적의 상태로 운용하기 위한 조종에 유용하게 이용할 수 있다.Sending information that converts the irradiation angle of sunlight into an electric signal can be useful for manipulating the device that uses sunlight.

'햇빛추적기'로는 간단하고 싼 비용으로 최적의 햇빛 방향을 실시간으로 결정할 수 있고 그 결정된 정보를 이용하여 햇빛을 이용하는 기기들의 효율을 높일 수 있다.With 'Sunlight Tracker', it is possible to determine the optimal sunlight direction in real time at a simple and low cost, and use the determined information to increase the efficiency of sunlight-using devices.

즉, 실시간으로 추적된 햇빛의 조사각도는 햇빛을 이용하는 기기를 최적의 상태로 운용하는데 유용하게 이용될 수 있다.That is, the irradiation angle of sunlight tracked in real time may be usefully used to optimally operate a device using sunlight.

첨부된 도면을 참조하여 '햇빛추적기'에 대해서 설명한다.A sunlight tracker will be described with reference to the accompanying drawings.

이 발명의 목적은 간단하고 싼 비용으로 최적의 햇빛의 조사각도를 추적하는 것으로, 실시간으로 추적된 햇빛의 조사각도는 햇빛을 이용하는 기기를 최적의 상태로 운용하는데 유용하게 이용될 수 있다.An object of the present invention is to track the optimal irradiation angle of sunlight at a simple and low cost, and the irradiation angle of sunlight tracked in real time may be usefully used to optimally operate a device using sunlight.

햇빛추적기의 작동원리는, 현재의 햇빛의 조사각도는 현재의 출력이 최대인 태양전지(3)를 내장한 태양전지판(2)에 수직일 것이므로 이 각도를 추적하는 것이다. 언제 어디서 햇빛이 비추더라도 가장 출력이 큰 전지를 추출하여 햇빛의 조사각도를 실시간으로 추적하기 위하여, 동일한 모양과 사양을 가진 태양전지가 내장된 태양전지판들을 반구형의 조형물의 외면에 접하는 형태로 배열하고, 컨트롤러로 각 태양전지의 출력을 연속으로 검출하고 비교하여 가장 출력이 큰 전지를 추출하여서, 그 태양전지를 내장한 태양전지판의 기울기를 콘트롤러에 기억되어 있는 각 태양전지판들의 기울기를 추적한다.The principle of operation of the sunlight tracker is to track this angle since the irradiation angle of the current sunlight will be perpendicular to the solar panel 2 containing the solar cell 3 with the maximum current output. Whenever and where sunlight shines, in order to extract the largest output battery and track the irradiation angle of sunlight in real time, the solar panels with the same shape and specification are arranged in contact with the outer surface of the hemispherical sculpture. The controller continuously detects and compares the output of each solar cell, extracts the largest output cell, and tracks the slope of each solar panel stored in the controller.

도 1은 햇빛추적기의 입면도와 평면도의 예시도이다.1 is an exemplary view of an elevation and a plan view of a sunlight tracker.

그림에서와 같이 태양전지(3)를 내장한 태양전지판(2)들을 수평한 베이스(1)에 반구형에 접면(원구에 접하는 면이 원구의 중심점에서 원구에 접하는 점을 연결하는 선에 대해 수직인 면)의 형태로 배열시키면 태양전지판의 기울기가 상하좌우 전 방향으로 배치된다.As shown in the figure, the solar panels (2) incorporating the solar cells (3) are in contact with the hemispherical shape on the horizontal base (1) (the surface of the sphere is perpendicular to the line connecting the point of contact with the sphere at the center of the sphere. In the form of a plane), the inclination of the solar panel is arranged in all directions up, down, left and right.

이 상태에서 최대의 출력을 내는 태양전지를 추출하면 그 태양전지가 장착된 태양전지판의 기울기가 햇빛방향의 수직에 가장 근접한 각도임을 알 수 있다.Extracting the solar cell with the maximum output in this state, it can be seen that the inclination of the solar panel on which the solar cell is mounted is the angle closest to the perpendicular to the sunlight direction.

설치시에 기준선(4)을 동서남북 중의 한 방향으로 정확하게 일치시켜야 운용하기가 쉽다.At the time of installation, it is easy to operate when the baseline 4 is exactly aligned in one direction of east, west, north and south.

'햇빛추적기'에 내장된 컨트롤러는 동일한 모양과 사양을 가진 태양전지들을 반구형의 형태로 배열시킨 각 태양전지의 출력을 연속으로 검출하고 시시각각으로 비교하여 가장 출력이 큰 전지를 선출하면, 이미 알고 있는 그 전지의 상하 및 좌우의 기울기에 따라 현재의 장소와 시간에서의 햇빛이 쪼이는 방향을 감지할 수 있다. 즉 태양전지에서 발전되는 전기를 모니터하여, 햇빛을 이용하는 기기가 최적상태를 유지하도록 햇빛의 조사방향을 실시간으로 추적하는 기술이다.The controller embedded in the 'Sunlight Tracker' continuously detects the output of each solar cell arranged in a hemispherical shape with the same shape and specifications, and compares them at every instant. According to the tilt of the battery up, down, left and right, it is possible to detect the direction of sunlight from the current place and time. In other words, by monitoring the electricity generated from the solar cell, the technology that tracks the direction of sunlight irradiation in real time to maintain the optimum state of the device using the sunlight.
