Description

각도조절이 가능한 반사판을 구비한 태양광 발전장치{Photovoltaic apparatus comprising angle-adjustable reflecting plate} Photovoltaic apparatus comprising angle-adjustable reflecting plate

본 발명은 태양광 발전장치에 관한 것으로서, 구체적으로는 태양전지판의 단부에 반사판을 장착함으로써 발전효율을 획기적으로 향상시킨 발전장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic device, and more particularly, to a power generation device that dramatically improves power generation efficiency by attaching a reflector to an end portion of a solar panel.

최근 화석 자원의 고갈에 대비하여 태양광, 풍력, 조력 등의 대체에너지에 대한 연구가 활발하게 진행되고 있다. 이 중에서도 태양광을 이용하여 전기를 생산하는 태양광 발전장치나 온수 등을 생산하는 태양광 집열장치 등은 이미 광범위하게 사용되고 있다.In preparation for the depletion of fossil resources, research on alternative energy such as solar light, wind power, and tidal power has been actively conducted. Among these, photovoltaic devices that generate electricity using solar light and solar heat collecting devices that produce hot water are already widely used.

태양광 발전에는 PN접합구조를 가지는 반도체소자인 전지셀(cell)이 사용되며, 전지셀은 태양광에 의해 반도체의 내부에서 여기된 소수 캐리어가 확산함으로써 기전력을 발생시킨다. 전지셀은 단결정 실리콘, 다결정 실리콘, 비정질 실리콘, 화합물 반도체 등으로 제조되며, 통상 다수의 전지셀을 소정 크기의 프레임에 장착하여 모듈화한 태양전지판이 많이 사용되고 있다.In solar power generation, a battery cell, which is a semiconductor device having a PN junction structure, is used. The battery cell generates electromotive force by diffusion of a small number of carriers excited inside the semiconductor by sunlight. Battery cells are made of monocrystalline silicon, polycrystalline silicon, amorphous silicon, compound semiconductors, and the like, and a large number of solar cells that are modularized by mounting a plurality of battery cells in a predetermined size frame are commonly used.

태양광 발전장치는 고정식과 추적식으로 구분될 수 있다. 고정식은 연중 일조시간이 긴 지역을 선정하여 태양전지판을 대규모로 설치하는 경우와, 주택 등의 지붕에 태양전지판을 소규모로 설치하는 경우가 있다. 추적식은 제한된 크기의 태양전지판에서 최대한의 발전효율을 얻을 수 있도록 고도와 방위각을 변화시켜 태양전지판이 항상 태양을 향하도록 설치하는 방식이다. 추적식에는 고도를 일정하게 유지한 채 방위각만을 변화시키는 방식도 있다.Photovoltaic devices can be divided into fixed and tracked. In the fixed type, solar panels are installed on a large scale by selecting an area with long sunshine hours throughout the year, and a small number of solar panels are installed on a roof of a house. The tracking type is a method in which the solar panels are always facing the sun by changing the altitude and azimuth angle to obtain the maximum power generation efficiency from the limited size solar panels. There is also a tracking method that changes only the azimuth angle while keeping the altitude constant.

추적식 태양광 발전장치(10)는 도 1의 개략도에 나타낸 바와 같이, 태양전지판(12)과, 태양전지판(12)이 태양을 향한 채 소정 각도를 유지하도록 지지하는 지지대(14), 지지대(14)의 상단부에 설치되어 태양전지판(12)의 고도각과 방위각을 조절하는 구동부(16)를 포함한다.As shown in the schematic diagram of FIG. 1, the tracking photovoltaic device 10 includes a solar panel 12 and a support 14 for supporting the solar panel 12 to maintain a predetermined angle toward the sun. It is installed on the upper end of 14) includes a drive unit 16 for adjusting the altitude and azimuth of the solar panel 12.

그런데 태양전지판(12)을 고정식으로 설치하든 추적식으로 설치하든 종래의 태양광 발전장치(10)는 태양전지판(12)에 직접 조사(照射)된 태양광만을 이용하므로 단위 태양전지판(12)의 발전량을 높이는 데는 근본적인 한계를 갖고 있다.However, whether the solar panel 12 is fixedly installed or tracked, the conventional photovoltaic device 10 uses only the sunlight directly irradiated to the solar panel 12, so that the unit solar panel 12 is There is a fundamental limit to increasing power generation.

본 발명은 이러한 문제점을 해결하기 위한 것으로서, 태양전지판에 직접 조사되는 태양광뿐만 아니라 태양전지판의 영역을 벗어난 태양광까지도 발전에 이용함으로써 단위 태양전지판의 발전량을 높이는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and its purpose is to increase the amount of generation of a unit solar panel by using not only sunlight directly irradiated to the solar panel but also solar light outside the region of the solar panel.

본 발명은 전술한 목적을 달성하기 위하여, 태양광을 이용하여 기전력을 발생시키는 전지셀이 장착된 태양전지판; 상기 태양전지판의 적어도 일측에 회전 가능하게 장착되어 태양광을 상기 태양전지판의 전체면으로 반사시키는 반사판; 상기 반사판을 상기 태양전지판에 대하여 회전시키는 반사판구동부를 포함하는 태양광 발전장치를 제공한다.The present invention in order to achieve the above object, a solar cell panel equipped with a battery cell for generating an electromotive force using sunlight; A reflection plate rotatably mounted on at least one side of the solar panel to reflect sunlight to the entire surface of the solar panel; It provides a photovoltaic device including a reflector plate driving unit for rotating the reflector with respect to the solar panel.

상기 태양광 발전장치에서 상기 반사판은 상기 태양전지판의 수광영역과 동일한 크기를 가지며, 상기 태양전지판의 일단에 장착된 제1 반사판과 상기 태양전지판의 상기 일단과 대향하는 타단에 장착된 제2 반사판을 포함하는 것을 특징으로 할 수 있다.In the photovoltaic device, the reflecting plate has the same size as the light receiving area of the solar panel, and includes a first reflecting plate mounted on one end of the solar panel and a second reflecting plate mounted on the other end opposite to the one end of the solar panel. It may be characterized by including.

또한 상기 태양전지판은, 상기 전지셀이 장착되는 히트싱크; 상기 히트싱크의 표면에 형성된 홈에 매설된 냉매관; 상기 히트싱크의 상기 표면에 부착되어 상기 냉매관을 커버하는 덮개를 포함하는 것을 특징으로 할 수 있다.In addition, the solar panel, the heat sink is mounted to the battery cell; A refrigerant pipe embedded in a groove formed on a surface of the heat sink; It may be characterized in that it comprises a cover attached to the surface of the heat sink to cover the refrigerant pipe.

본 발명에 따르면 태양전지판의 단부에 장착된 반사판에서 반사된 빛이 태양전지판의 전체면으로 조사되므로 종래에 비해 태양전지판에 조사되는 광량이 크게 증가하며 이에 따라 발전량이 크게 증대될 수 있다. 따라서 설치면적이 상대적으로 제한된 가로등, 주택 등에 설치되는 소규모 태양광 발전장치의 활용성이 크게 증대될 수 있다.According to the present invention, since the light reflected from the reflecting plate mounted at the end of the solar panel is irradiated to the entire surface of the solar panel, the amount of light irradiated to the solar panel is greatly increased compared to the prior art, and thus the amount of power generation can be greatly increased. Therefore, the utility of the small solar photovoltaic device installed in a streetlight, house, etc., the installation area is relatively limited can be greatly increased.

도 2는 본 발명의 실시예에 따른 태양전지모듈(100)을 나타낸 것이다. 본 발명에 따른 태양전지모듈(100)은 태양광을 이용하여 기전력을 발생시키는 태양전지판(110), 태양전지판(110)의 상단과 하단에 각각 결합된 제1 반사판(121)과 제2 반사판(122)을 구비한다.2 shows a solar cell module 100 according to an embodiment of the present invention. The solar cell module 100 according to the present invention includes a solar panel 110 that generates electromotive force using sunlight, a first reflecting plate 121 and a second reflecting plate coupled to upper and lower ends of the solar panel 110, respectively. 122).

태양전지판(110)은 소정 프레임에 다수의 전지셀(cell)이 장착된 것으로서 전지셀은 공지된 제품을 사용하므로 이에 대한 설명은 생략하기로 한다.Since the solar panel 110 is provided with a plurality of battery cells in a predetermined frame, the battery cell uses a known product, and thus description thereof will be omitted.

제1 반사판(121)과 제2 반사판(122)은 태양전지판(110)의 수광영역을 벗어난 태양광을 태양전지판(110)의 전체 표면으로 반사시키기 위한 것으로서 반사율이 높은 금속재질일 수도 있고, 그 표면에 거울이 부착된 것일 수도 있다.The first reflecting plate 121 and the second reflecting plate 122 are for reflecting the sunlight out of the light receiving region of the solar panel 110 to the entire surface of the solar panel 110 may be a metal material having a high reflectance. The mirror may be attached to the surface.

제1 반사판(121)은 제1 힌지(131)를 이용하여 태양전지판(110)의 상단에 회전 가능하게 결합되고, 제2 반사판(122)은 제2 힌지(132)를 이용하여 태양전지판(110)의 하단에 회전 가능하게 결합되는 것이 바람직하다. The first reflecting plate 121 is rotatably coupled to the upper end of the solar panel 110 using the first hinge 131, and the second reflecting plate 122 is the solar panel 110 using the second hinge 132. It is preferable to be rotatably coupled to the bottom of the).

또한 제1 반사판(121)과 제2 반사판(122)은 각각 태양전지판(110)의 수광영역과 동일한 크기를 가지는 것이 바람직하다. 수광영역은 전지셀이 장착된 영역으로 정의한다. 즉, 제1 반사판(121)과 제2 반사판(122)의 세로 및 가로의 길이는 각각 태양전지판(110)의 수광영역의 세로 및 가로의 길이와 동일한 것이 바람직하다. In addition, the first reflecting plate 121 and the second reflecting plate 122 may each have the same size as the light receiving region of the solar panel 110. The light receiving area is defined as an area in which a battery cell is mounted. That is, the lengths of the first and second reflecting plates 121 and 122 are equal to the lengths of the vertical and horizontal lengths of the light receiving regions of the solar panel 110, respectively.

제1 반사판(121)과 제2 반사판(122)의 각각에서 반사된 빛은 태양전지판(110)의 전체면에 조사될 수 있어야 하므로 제1 반사판(121)과 제2 반사판(122)은 태양전지판(110)의 표면에 대해 적절한 각도를 유지해야 한다.Since the light reflected from each of the first reflecting plate 121 and the second reflecting plate 122 should be irradiated to the entire surface of the solar panel 110, the first reflecting plate 121 and the second reflecting plate 122 may be a solar panel. An appropriate angle should be maintained with respect to the surface of (110).

제1 반사판(121)과 제2 반사판(122)의 각도를 적절히 유지하기 위해서는 도 3에 도시된 바와 같이 제1 반사판(121)과 제2 반사판(122)을 각각 회전시키기 위한 제1 반사판구동부(141)와 제2 반사판구동부(142)를 설치하는 것이 바람직하다. In order to properly maintain the angles of the first reflecting plate 121 and the second reflecting plate 122, as shown in FIG. 3, the first reflecting plate driver for rotating the first reflecting plate 121 and the second reflecting plate 122 ( 141 and the second reflector plate driver 142 are preferably provided.

제1 및 제2 반사판구동부(141,142)는 스텝모터 등을 사용할 수 있으나, 이에 한정되는 것이 아니므로 다양한 형태의 구동수단이 사용될 수 있다. 예를 들어 일단은 지지대(도 4의 도면부호 14) 또는 태양전지판(110)에 연결되고 타단은 반사판(121,122)에 연결되어 신장 또는 수축하는 신축구동부를 이용하여 각 반사판(121,122)을 회전시킬 수도 있을 것이다.The first and second reflector driving parts 141 and 142 may use a step motor, but are not limited thereto. Various driving means may be used. For example, one end may be connected to a support (14 in FIG. 4) or the solar panel 110, and the other end may be connected to the reflector plates 121 and 122 to rotate each reflector plate 121 and 122 by using an expansion and contraction unit that extends or contracts. There will be.

본 발명에 따른 태양전지모듈(100)은 고정식 발전장치나 추적식 발전장치에 모두 사용될 수 있다. The solar cell module 100 according to the present invention can be used both in a stationary generator or a tracking generator.

도 4는 본 발명에 따른 태양전지모듈(100)을 추적식 발전장치에 사용한 모습을 나타낸 것으로서, 태양전지모듈(100)을 지지하는 지지대(14)와, 태양전지모듈(100)의 고도각과 방위각을 조절하는 구동부(16)를 구비한다.4 is a view showing a state in which the solar cell module 100 according to the present invention is used for the tracking type generator, the support 14 supporting the solar cell module 100, and the elevation angle and the azimuth angle of the solar cell module 100. It is provided with a driving unit 16 to adjust.

태양광 발전장치의 제어부(도시하지 않았음)는 태양의 위치를 감지하여 구동부(16)를 동작시킬 때는 필요에 따라서 태양전지모듈(100)의 제1 반사판구동부(141) 및/또는 제2 반사판구동부(142)를 제어하여 제1 반사판(121) 및/또는 제2 반사판(122)의 각도를 적절히 조절할 수 있다.The control unit (not shown) of the photovoltaic device senses the position of the sun to operate the driving unit 16 as necessary, when necessary, the first reflecting plate driver 141 and / or the second reflecting plate of the solar cell module 100. The driver 142 may be controlled to appropriately adjust the angles of the first reflector 121 and / or the second reflector 122.

고정식 발전장치에서도 제1 반사판구동부(141) 및/또는 제2 반사판구동부(142)를 적절히 제어하여 제1 반사판(121) 및/또는 제2 반사판(122)의 각도를 조절할 수 있음은 물론이다.In the stationary power generator, the first reflector plate 141 and / or the second reflector plate 142 may be properly controlled to adjust the angle of the first reflector 121 and / or the second reflector 122.

한편 전술한 바와 같이 태양전지모듈(100)의 상단과 하단에 반사판(121,122)이 장착된 경우에는 도 5에 도시된 바와 같이 태양전지모듈(100)을 일렬로 배열하여 한정된 공간에서도 발전효율을 극대화시킬 수 있을 것이다.Meanwhile, when the reflecting plates 121 and 122 are mounted on the top and bottom of the solar cell module 100 as described above, the solar cell module 100 is arranged in a line as shown in FIG. 5 to maximize power generation efficiency even in a limited space. You can do it.

이하에서는 도 6 및 도 7을 참조하여 본 발명의 실시예에 따른 태양전지모듈(100)의 동작을 설명한다.Hereinafter, the operation of the solar cell module 100 according to the embodiment of the present invention will be described with reference to FIGS. 6 and 7.

도 6은 태양전지판(110)이 태양광에 대해 수직방향으로 설치된 경우를 나타낸 것으로서, 이를 통해 태양전지판(110)에 직접 도달하는 태양광의 광폭은 D1 이지만, 제1 및 제2 반사판(121,122)에서 반사되어 태양전지판(110)에 도달하는 태양광을 포함하는 전체 광폭은 D2 이고, D2가 D1보다 훨씬 큰 것을 알 수 있다.FIG. 6 illustrates a case in which the solar panel 110 is installed in the vertical direction with respect to sunlight, and the width of sunlight directly reaching the solar panel 110 is D1, but the first and second reflectors 121 and 122 may be used. It can be seen that the total width including the sunlight reflected and reaching the solar panel 110 is D2, and D2 is much larger than D1.

한편 고정식 발전장치나 방위각만을 조절하는 추적식 발전장치에서는 태양전지판(110)이 태양광에 대해 항상 수직을 유지하지는 않으므로 이 경우에도 제1 및 제2 반사판(121,122)의 각도를 적절히 조절해 줄 필요가 있다. 도 7은 이러한 경우를 나타낸 것으로서 태양전지판(110)이 태양광에 대해 수직이 아닌 경우에도 제1 및 제2 반사판(121,122)의 각도를 적절히 조절하여 반사광을 태양전지판(110)의 전체면으로 조사할 수 있음을 알 수 있다. 또한 이 경우에도 태양전지판(110)에 직접 도달하는 태양광의 광폭은 D3 이지만, 제1 및 제2 반사판(121,122)에서 반사되어 태양전지판(110)에 도달하는 태양광을 포함하는 전체 광폭은 D4 이고, D4가 D3보다 훨씬 큰 것을 알 수 있다.On the other hand, since the solar panel 110 does not always maintain perpendicularity to sunlight in the fixed power generator or the tracking power generator that adjusts only the azimuth angle, the angles of the first and second reflectors 121 and 122 need to be properly adjusted. There is. 7 illustrates such a case, even when the solar panel 110 is not perpendicular to the sunlight, the reflected light is irradiated to the entire surface of the solar panel 110 by appropriately adjusting the angles of the first and second reflecting plates 121 and 122. It can be seen that. In this case, the width of sunlight directly reaching the solar panel 110 is D3, but the total width including sunlight reflected from the first and second reflectors 121 and 122 to reach the solar panel 110 is D4. We can see that D4 is much larger than D3.

이와 같이 본 발명의 실시예에 따른 태양전지모듈(100)은 태양전지판(110)의 본래의 수광면적보다 훨씬 넓은 면적의 태양광을 수광할 수 있으므로 발전량을 크게 늘릴 수 있다. 특히 이러한 장점으로 인해 설치면적이 상대적으로 제한된 가로등, 주택 등에 설치되는 소규모 태양광 발전장치의 활용성이 크게 증대될 것으로 기대된다.As described above, the solar cell module 100 according to the embodiment of the present invention can receive sunlight having a much larger area than the original light receiving area of the solar panel 110, and thus can greatly increase the amount of power generated. In particular, due to these advantages, it is expected that the utility of small-scale photovoltaic devices installed in street lamps and houses with relatively limited installation area will be greatly increased.

한편 본 발명의 실시예에 따르면 태양전지판(110)이 일반적인 경우보다 훨씬 많은 태양광을 수광하므로 과열로 인한 발전효율저하를 막기 위해서는 태양전지판(110)을 적절히 냉각시킬 필요가 있다.Meanwhile, according to the embodiment of the present invention, since the solar panel 110 receives much more sunlight than the general case, it is necessary to cool the solar panel 110 appropriately in order to prevent power generation efficiency degradation due to overheating.

이를 위해서는 도 8의 평면도에 도시된 바와 같이 다수의 전지셀(111)을 히트싱크(113)의 상면에 부착하고, 히트싱크(113)의 내부에 냉매가 유동하는 냉매관(117)을 매설하는 것이 바람직하다. 히트싱크(113)는 열전도율이 높은 알루미늄 등의 금속재질인 것이 바람직하고, 냉매관(117)은 구리 재질의 관인 것이 바람직하다.To this end, as illustrated in the plan view of FIG. 8, a plurality of battery cells 111 are attached to an upper surface of the heat sink 113, and a refrigerant pipe 117 through which refrigerant flows is embedded in the heat sink 113. It is preferable. The heat sink 113 is preferably made of metal such as aluminum having high thermal conductivity, and the refrigerant tube 117 is preferably made of copper.

전지셀(111)이 태양광을 수광하여 고온으로 가열되면 히트싱크(113)도 따라서 가열된다. 이때 입구(118)로부터 냉매를 주입하면 냉매관(117)을 따라 유동하는 냉매가 히트싱크(113)의 열을 전달받아 가열된 후 출구(119)로 배출된다. 만일 물을 냉매로 사용하면 출구(119)에서 배출된 온수를 축열탱크에 저장하여 욕실용 또는 난방용 온수로 사용할 수 있다.When the battery cell 111 receives the sunlight and is heated to a high temperature, the heat sink 113 is also heated accordingly. In this case, when the refrigerant is injected from the inlet 118, the refrigerant flowing along the refrigerant pipe 117 is heated by receiving heat from the heat sink 113 and then discharged to the outlet 119. If water is used as the refrigerant, hot water discharged from the outlet 119 may be stored in the heat storage tank and used as hot water for bathroom or heating.

도 9는 냉매관(117)의 매설방법을 나타내기 위하여 도 8의 A-A'선에 따른 단면을 나타낸 것이다. 구체적으로 살펴보면, 히트싱크(113)의 표면에 전체면을 왕복하는 연속된 홈(114)을 형성하고, 홈(114)을 따라 냉매관(117)을 삽입한 상태에서 덮개(115)를 장착함으로써 간단히 냉매관(117)을 설치할 수 있다.9 is a cross-sectional view taken along line AA ′ of FIG. 8 to illustrate a method of embedding the refrigerant pipe 117. Looking specifically, by forming a continuous groove 114 to reciprocate the entire surface on the surface of the heat sink 113, by mounting the cover 115 in the state in which the refrigerant pipe 117 is inserted along the groove 114 The refrigerant pipe 117 can be simply installed.

한편 이상에서는 태양전지판(110)의 상단과 하단에 제1 반사판(121)과 제2 반사판(122)이 서로 대향하도록 설치되는 경우를 설명하였으나 이것은 도 5에 도시된 바와 같이 태양전지판(110)을 가로로 연속 배열하는 경우에 적합한 것이다.Meanwhile, in the above description, a case in which the first reflecting plate 121 and the second reflecting plate 122 are installed on the top and bottom of the solar panel 110 to face each other is described, but this is illustrated in FIG. 5. It is suitable for the case of horizontal arrangement.

따라서 설치면적이 세로로 좁게 형성되는 경우에는 태양전지판의 좌측단과 우측단에 각각 반사판을 설치하는 것도 가능하다.Therefore, when the installation area is formed to be narrow vertically, it is also possible to provide a reflecting plate on the left end and the right end of the solar panel, respectively.

또한 설치면적 등을 고려하여 반사판 1개만을 태양전지판(110)의 일단에 설치하는 것도 가능하다. 또한 하나의 태양전지판(110)만을 사용하는 경우에는 각 변에 반사판을 각각 설치하는 것도 가능할 것이다.In addition, in consideration of the installation area, only one reflector may be installed at one end of the solar panel 110. In addition, when only one solar panel 110 is used, it may be possible to install reflecting plates on each side.

이 밖에도 본 발명은 전술한 실시예에 한정되지 않고 다양한 형태로 변형 또는 수정될 수 있으며, 변형 또는 수정된 실시예도 후술하는 특허청구범위에 포함된 본 발명의 기술적 사상을 포함한다면 본 발명의 권리범위에 포함됨은 당연하다 할 것이다.In addition, the present invention is not limited to the above-described embodiment may be modified or modified in various forms, and the modified or modified embodiment also includes the technical scope of the present invention included in the claims to be described later the scope of the present invention Included in would be natural.
