태양광발전분야Solar power generation field

태양광발전은 신재생에너지의 일종으로 인류가 선택한 가장 확실한 미래 에너지원 중의 하나이다. 그러나 발전효율이 낮은 것이 단점이라서 효율 향상에 많은 기술개발이 이루어지고 있다. 출원번호 10-2013-0003199[양면수광형 태양전지의 제조방법] 등에 의해 태양광전지패널의 양면에서 태양광을 수광하여 발전을 할 수 있는 태양전지가 개발되어 사용중이다. 본 출원인은 출원번호 10-2017-0161175[발전단지 바닥구조를 개선하여 성능을 향상시킨 태양광발전시스템]을 통하여 태양광발전단지에 형성되는 태양광전지패널(11)들 사이에 유지보수를 위해 사람들이 다닐 수 있는 통로/여유공간(14)에 조사되는 태양광을 태양광전지패널(11) 위로 반사시켜 발전효율을 향상시키도록 다각도평면반사체조합을 설치하는 발명을 한 바 있다. 그러나 이 발명은 태양광전지패널(11) 상부면에서만 발전이 가능한 경우에만 적용이 가능하다. Photovoltaic power generation is one of the most reliable sources of future energy chosen by mankind as a type of renewable energy. However, the low power generation efficiency is a disadvantage, so many technologies are being developed to improve the efficiency. A solar cell capable of generating power by receiving sunlight from both sides of a solar cell panel has been developed and in use by application number 10-2013-0003199 [Method of manufacturing double-sided light-receiving solar cell]. The applicant of the present invention is for maintenance between the photovoltaic panels 11 formed in the photovoltaic power generation complex through the application number 10-2017-0161175 [solar power generation system with improved performance by improving the power generation complex floor structure]. There has been an invention of installing a multi-angle planar reflector combination to improve power generation efficiency by reflecting sunlight irradiated on the passage/free space 14 through which it can travel onto the solar cell panel 11. However, this invention is applicable only when power generation is possible only on the upper surface of the solar cell panel 11.

따라서 양면에서 태양광을 수광하여 태양광발전을 할 수 있는 양면수광형태양광전지패널(22)이 사용되는 태양광발전시스템에는 이에 맞는 다른 형태의 반사체가 필요하다. 그러나 양면수광형태양광전지패널(22)의 하부면에 태양광을 반사시켜 발전효율을 향상시키는 기술은 아직 개발되지 않고 있다.Therefore, a photovoltaic power generation system in which the double-sided light-receiving type photovoltaic cell panel 22 capable of generating photovoltaic power by receiving sunlight from both sides requires another type of reflector suitable for this. However, a technology for improving power generation efficiency by reflecting sunlight on the lower surface of the double-sided light-receiving type photovoltaic panel 22 has not yet been developed.

본 발명에서는 양면수광형태양광전지패널(22)의 하부면으로 태양광을 많이 조사시키는 반사체 구성을 제시한다. 양면수광형태양광전지패널(22)의 경우 상부면에 조사된 태양광이 양면수광형태양광전지를 통과하여 하부면으로 투과하는 성질이 있으므로 투과한 태양광을 다시 양면수광형태양광전지 하부면에 효과적으로 조사될 수 있는 방안을 제안한다. 그리고 주변에 조사되는 태양광을 양면수광형태양광전지패널(22) 하부면에 조사될 수 있도록 양면수광형태양광전지패널(22)의 직하를 벗어난 여유공간에까지도 설치될 수 있는 보조하는 반사체를 추가로 설치하는 방안도 강구한다. 태양광발전을 위한 설치입지가 부족한 점을 감안하여, 하부는 다른 용도로 공간을 사용하고 상부는 태양광발전설비를 설치하는 공중부양형태양광발전시스템에도 효율적으로 적용할 수 있는 방법도 강구한다. 특히 주차장 지붕에 설치되는 공중부양형태양광발전시스템 또는 논이나 밭에 설치되는 공중부양형태양광발전시스템에 반사되는 태양광의 량을 극대화시키는 효과적인 방법을 강구한다.In the present invention, a reflector configuration that irradiates a lot of sunlight to the lower surface of the double-sided light-receiving type photovoltaic cell panel 22 is proposed. In the case of the double-sided light-receiving type photovoltaic cell panel 22, since the solar light irradiated on the upper surface passes through the double-sided light-receiving type photovoltaic cell and transmits to the lower surface, the transmitted sunlight is effectively transferred back to the lower side of the double-sided light-receiving type photovoltaic cell. Suggest a way to be investigated. In addition, an auxiliary reflector that can be installed even in the free space outside of directly under the double-sided light-receiving type photovoltaic cell panel 22 is added so that the surrounding sunlight can be irradiated to the lower surface of the double-sided light-receiving type photovoltaic cell panel 22. Also devised a plan to install it. Considering the lack of installation location for photovoltaic power generation, a method that can be efficiently applied to a levitation type photovoltaic power generation system where the lower part uses space for other purposes and the upper part installs photovoltaic power generation facilities is also devised. In particular, an effective method of maximizing the amount of sunlight reflected by a levitation type photovoltaic power generation system installed on the roof of a parking lot or a levitation type photovoltaic power generation system installed in a rice field or field is devised.

수상 또는 지상에 설치되는 양면수광형태양광전지패널(22)에 있어서, 양면수광형태양광전지패널(22)을 투과한 태양광이나 주변에 조사되는 태양광을 양면수광형태양광전지패널(22) 하부면 위에 효과적으로 반사되도록 양면수광형태양광전지패널(22) 하부에 다양한 형태의 반사체를 설치하여 과제를 해결한다. 특히 주차장 지붕에 설치되는 공중부양형 태양광발전시스템이나 논이나 밭에 설치되는 공중부양형 영농형태양광발전시스템에도 양면수광형태양광전지패널(22)을 설치하고 동일한 방법을 적용하여 과제를 해결한다.In the double-sided light-receiving type photovoltaic cell panel 22 installed on the water or the ground, sunlight transmitted through the double-sided light-receiving type photovoltaic cell panel 22 or the sunlight irradiated to the surroundings is transmitted under the double-sided light-receiving type photovoltaic cell panel 22 Various types of reflectors are installed under the double-sided light-receiving type positive photovoltaic cell panel 22 so as to be effectively reflected on the surface to solve the problem. In particular, the problem is solved by installing a double-sided photovoltaic cell panel 22 in the levitation type photovoltaic power generation system installed on the roof of the parking lot or the levitation farming type photovoltaic power generation system installed in the rice field or field and applying the same method. .

양면수광형태양광전지패널(22)는 현재 개발되어 사용되고 있으며 양쪽 면에서 태양광을 수광할 수 있으므로 보통 수직으로 세워서 설치하는 방음벽 대용 등의 경우에 적용하여 사용된다. 그리고 일반적인 태양광전지패널(11)과 같이 경사지게 설치하는 경우 양면수광형태양광전지패널(22)을 투과한 태양광 이외에 하부면에는 태양광이 거의 조사되지 않아서 발전효율이 낮은 편이다. The double-sided light-receiving type double-sided photovoltaic panel 22 is currently developed and used, and can receive sunlight from both sides, so it is applied and used in the case of a soundproof wall that is usually installed vertically. In addition, when the solar cell panel 11 is installed in an inclined manner, the lower surface is hardly irradiated with sunlight other than the sunlight that has passed through the double-sided light-receiving type photovoltaic cell panel 22, resulting in low power generation efficiency.

본 발명에서는 양면수광형태양광전지패널(22)을 일반적인 태양광전지패널(11)과 같이 경사지게 설치하는 경우 하부면에도 태양광이 더 많이 조사될 수 있도록 설치된 양면수광형태양광전지패널(22)의 하부면에 하부면반사체(21)를 추가로 설치하였다. 여기에 더하여 하부면반사체(21)에 연접하여 상부면으로 유입되는 반사광을 늘리기 상부광유입반사체(31)를 추가로 설치하거나 하부면으로 유입되는 반사광을 늘리기 하부광유입반사체(41)를 추가로 설치하여 발전효율을 대폭 향상시켰다. 특히 주차장지붕에 설치되는 공중부양형 태양광발전시스템이나 논이나 밭에 설치되는 공중부양형 태양광발전시스템에도 동일한 방법으로 반사체를 설치하여 발전효율을 대폭 향상시켰다. 실험결과 발전효율이 약40% 내외로 향상되는 결과를 실증하였다. 특히 양면수광형태양광전지패널(22)의 하부면에 반사판(23)을 직접 부착시킨 반사체일체형패널(80)을 적용하여 공사시공의 편리성과 구조물 구성을 단순화시키는 획기적인 결과를 확인하였다.In the present invention, when the double-sided light-receiving type photovoltaic panel 22 is installed in an inclined manner like a general solar photovoltaic panel 11, the lower part of the double-sided light-receiving type photovoltaic panel 22 is installed so that more sunlight can be irradiated to the lower surface. A lower surface reflector 21 was additionally installed on the surface. In addition to this, increase the reflected light flowing into the upper surface by connecting to the lower surface reflector 21 Additional installation of the upper light inflow reflector 31 or increase the reflected light flowing into the lower surface Add the lower light inflow reflector 41 Installed, greatly improved the power generation efficiency. In particular, the levitation type solar power generation system installed on the roof of the parking lot and the levitation type solar power generation system installed in the paddy field or field were installed in the same way, and the power generation efficiency was greatly improved. As a result of the experiment, it was verified that the power generation efficiency was improved by about 40%. In particular, by applying the reflector integrated panel 80 in which the reflector 23 is directly attached to the lower surface of the double-sided light-receiving type photovoltaic cell panel 22, the remarkable result of simplifying the construction and construction of the structure was confirmed.

도 1은 기존 발전단지 바닥에 설치된 다각도평면반사체조합 설명도이다. 지상 또는 수상 태양광발전단지에는 태양광을 조사받는 태양광전지패널(11)들이 바닥(13)에 기초한 지지대(12)에 의해 설치되며 태양광전지패널(11)들 사이에는 태양광전지패널(11)들 간의 태양광조사 간섭을 피하고 유지보수를 위해 사람들이 다닐 수 있는 통로/여유공간(14)이 형성되는 것이 일반적이다. 통로/여유공간(14)에 도달하는 태양광을 뒤편에 설치된 태양광전지패널(11) 위로 반사시켜 발전효율을 높이기 위하여 통로/여유공간(14)의 바닥(13) 위에 고각도평면반사체(15), 중각도평면반사체(16), 저각도평면반사체(17)의 조합인 다각도평면반사체조합(10)을 설치하는 발명은 이미 본 출원인이 출원한 바 있다. 태양광전지패널(11)의 일종으로 패널 양쪽면에 태양광전지가 형성된 양면수광형태양광전지패널(22)의 경우 양쪽 면에서 태양광발전을 할 수 있다. 이 경우에는 양면수광형태양광전지패널(22)의 하부면에 설치된 태양광전지에 많은 태양광이 조사되도록 강구하는 노력이 필요하며, 기존의 반사체와 다른 구성을 형성해야 한다. 1 is an explanatory diagram of a combination of a multi-angle plane reflector installed on the floor of an existing power generation complex. Photovoltaic panels (11) to be irradiated with sunlight are installed in the above-ground or floating photovoltaic power generation complex by a support (12) based on the floor (13), and between the photovoltaic panels (11), photovoltaic panels (11) are In general, a passage/free space 14 that people can carry around is formed for maintenance and avoiding interference with sunlight irradiation between the liver. A high-angle plane reflector 15 on the floor 13 of the passage/free space 14 to increase power generation efficiency by reflecting the sunlight reaching the passage/free space 14 onto the solar panel 11 installed at the rear. , The invention of installing the multi-angle planar reflector combination 10, which is a combination of the mid-angle plane reflector 16 and the low-angle plane reflector 17, has already been filed by the present applicant. As a type of solar cell panel 11, in the case of a double-sided light-receiving type photovoltaic cell panel 22 in which solar cells are formed on both sides of the panel, solar power can be generated from both sides. In this case, it is necessary to make an effort to irradiate a lot of sunlight to the solar cell installed on the lower surface of the double-sided light-receiving type photovoltaic cell panel 22, and a configuration different from the existing reflector must be formed.

도 2는 양면수광형태양전지패널에 하부면반사체가 설치된 사례 설명도이다. 태양광전지패널(11)의 일종으로 패널 양쪽면에서 태양광을 수광하여 발전하는 양면수광형태양광전지패널(22)가 개발되어 사용되고 있다. 태양과 마주치는 상부면은 발전효율이 높지만 하부면은 직접 태양광이 조사되지 않고 양면수광형태양광전지패널(22)을 투과한 태양광 또는 주변에 확산되는 태양광으로 발전하므로 발전효율이 낮은 편이다. 따라서 양면수광형태양광전지패널(22)의 하부면 발전효율을 높이기 위하여 양면수광형태양광전지패널(22)의 하부면에 태양광을 반사시키도록 구성하는 것이 본 발명의 핵심요소이다. 패널 양쪽면에서 태양광을 수광하여 태양광발전을 하는 양면수광형태양광전지패널(22)이 바닥(13)에 기초한 지지대(12)에 의해 설치되는 수상 또는 지상 태양광발전장치에 있어서, 양면수광태양광전지패널(22)을 투과한 태양광이나 주변에 직접 조사되거나 확산되는 태양광을 양면수광태양광전지패널(22) 하부면 위로 반사시키기 위하여 양면수광태양광전지패널(22) 하부면과 임의의 간격을 두고 마주보도록 하부면반사체(21)를 설치하되, 하부면반사체(21)가 양면수광태양광전지패널(22) 하부면 바닥(13) 일측에 설치되는데 반사된 태양광이 양면수광태양광전지패널(22) 하부면에 효과적으로 조사될 수 있도록 양면수광태양광전지패널(22) 하부면과 하부면반사체(21)의 반사면이 동일한 경사방향을 유지하면서 수평면과 임의의 각도로 경사를 이루도록 반사판받침대(24) 위에 반사판(23)을 고정시켜 만들어지도록 하부면반사체(21)를 구성하는 것이 특징이다. 설치를 편리하게 하고 풍압을 줄이기 위하여 반사판받침대(24)는 그림과 같이 밀폐된 통형상이 아니라 바람이 잘 통하는 다수의 지지대들의 결합(미도시)으로 만들 수도 있는데 간단하게는 반사판(23) 상하를 지지하는 2개의 지지대로 대신 할 수도 있다. 양면수광태양광전지패널(22)의 하부면 발전효율은 약20% 내외이나 본 발명에 따라 반사체를 설치하면 버려지는 태양광을 반사시켜 활용함으로써 발전효율이 매우 올라간다. 하부면반사체(21)는 풍압이나 외력에 견디도록 바닥(13)에 고정시키도록 한다. 2 is a diagram illustrating a case in which a lower surface reflector is installed on a double-sided light-receiving type positive battery panel. As a kind of solar cell panel 11, a double-sided light-receiving type photovoltaic cell panel 22 that receives sunlight from both sides of the panel to generate electricity has been developed and used. The upper surface facing the sun has high power generation efficiency, but the lower surface is not directly irradiated with sunlight, but the power generation efficiency is low because it is generated by sunlight transmitted through the double-sided photovoltaic cell panel 22 or diffused around to be. Therefore, in order to increase the power generation efficiency of the lower surface of the double-sided light-receiving type photovoltaic cell panel 22, it is a core element of the present invention to reflect sunlight on the lower surface of the double-sided light-receiving type photovoltaic panel 22. In the floating or terrestrial photovoltaic power generation device in which the double-sided light-receiving type photovoltaic cell panel 22 for photovoltaic power generation by receiving sunlight from both sides of the panel is installed by a support 12 based on the floor 13, double-sided light receiving Arbitrary distance from the lower surface of the double-sided photovoltaic panel 22 to reflect the sunlight transmitted through the photovoltaic panel 22 or sunlight directly irradiated or diffused to the surroundings onto the lower surface of the double-sided photovoltaic panel 22 The lower surface reflector 21 is installed so as to face each other, but the lower surface reflector 21 is installed on one side of the double-sided photovoltaic panel 22 and the bottom 13 of the lower surface. 22) Reflective plate support 24 so that the reflective surface of the lower surface of the double-sided photovoltaic cell panel 22 and the lower surface reflector 21 are inclined at an arbitrary angle with the horizontal surface while maintaining the same inclination direction so that the lower surface can be effectively irradiated. ) It is characterized by configuring the lower surface reflector 21 to be made by fixing the reflector 23 on the top. In order to facilitate installation and reduce wind pressure, the reflector support 24 may be made of a combination (not shown) of a number of supporters that pass through the air well, rather than a closed tubular shape as shown in the figure. It can also be replaced with two supporting supports. The power generation efficiency of the lower surface of the double-sided photovoltaic cell panel 22 is about 20%, but when a reflector is installed according to the present invention, the power generation efficiency is greatly increased by reflecting and utilizing the discarded sunlight. The lower surface reflector 21 is fixed to the floor 13 to withstand wind pressure or external force.

도 3은 상부광유입반사체가 추가된 사례 설명도이다. 통로/여유공간(14)으로 입사되는 태양광을 도2에서 보다 양면수광태양광전지패널(22) 하부면 위로 더 많이 반사시키기 위하여 경사를 이루고 설치되어 있는 하부면반사체(21)의 높은 측면에 연접하여 하부면반사체(21) 보다 수평면과 반사판이 이루는 각도가 더 크도록 만들어지는 상부광유입반사체(31)를 양면수광태양광전지패널(22) 하부면을 벗어나서 통로/여유공간(14) 일측에 추가로 설치하여 구성하는 것이 특징이다. 상부광유입반사체(31)는 양면수광태양광전지패널(22) 하부면을 벗어나는 통로/여유공간(14) 일측에 설치됨으로써 상부광유입반사체(31)와 양면수광태양광전지패널(22) 사이에 형성된 상부공간을 통하여 통로/여유공간(14)에 유입되는 더 많은 태양광을 양면수광태양광전지패널(22) 하부면으로 반사시킬 수 있다. 3 is an explanatory diagram of a case in which an upper light inflow reflector is added. In order to reflect more sunlight incident on the passage/free space 14 above the lower surface of the double-sided photovoltaic panel 22 than in FIG. 2, it is connected to the high side of the lower surface reflector 21 installed in an inclined manner. Thus, the upper light inflow reflector 31, which is made to have a larger angle between the horizontal surface and the reflector than the lower reflector 21, is added to one side of the passage/free space 14 outside the lower surface of the double-sided photovoltaic panel 22 It is characterized by installing and configuring it. The upper light inflow reflector 31 is formed between the upper light inflow reflector 31 and the double-sided photovoltaic cell panel 22 by being installed on one side of the passage/free space 14 outside the lower surface of the double-sided photovoltaic panel 22. More sunlight flowing into the passage/free space 14 through the upper space may be reflected to the lower surface of the double-sided photovoltaic panel 22.

도 5는 발전단지 전체에 반사체가 설치된 사례 설명도이다. 양면수광태양광전지패널(22)의 경우 양쪽면에서 모두 발전이 가능하므로 통로/여유공간(14)으로 입사되는 태양광을 양면수광태양광전지패널(22)의 상부면과 하부면에 나누어 일부씩 반사시켜 양쪽면의 발전효율을 동시에 높일 수 있다. 따라서 도5에서는 고각도평면반사체(15)와 중각도평면반사체(16)는 통로/여유공간(14)에 유입된 태양광 일부를 양면수광태양광전지패널(22)의 상부면으로 반사시키고, 하부면반사체(21)와 상부광유입반사체(31)는 통로/여유공간(14)에 유입된 태양광 일부를 양면수광태양광전지패널(22)의 하부면으로 반사시키는 사례를 도시하였다. 그 외에도 다양한 반사체들의 조합으로 목적에 맞는 구성을 할 수 있다. 상부면이나 하부면에 반사작용을 하는 반사판(23) 구조를 도10 내지 도12에서 도시한 바와 같이 하여 적용하는 것도 본 발명의 범위에 포함된다. 5 is a diagram illustrating a case in which a reflector is installed in the entire power generation complex. In the case of the double-sided photovoltaic panel 22, since power generation is possible on both sides, the sunlight incident on the passage/free space 14 is divided into the upper and lower surfaces of the double-sided photovoltaic panel 22 and partially reflected. So that the power generation efficiency of both sides can be increased at the same time. Therefore, in FIG. 5, the high-angle plane reflector 15 and the medium-angle plane reflector 16 reflect some of the sunlight flowing into the passage/free space 14 to the upper surface of the double-sided photovoltaic panel 22, and The surface reflector 21 and the upper light inflow reflector 31 show an example of reflecting some of the sunlight that has flowed into the passage/free space 14 to the lower surface of the double-sided photovoltaic panel 22.

In this way, since the upper part of the pillar 61 can generate photovoltaic power and the lower space can be used for other purposes, the utilization of the land 62 can be increased and residents' acceptance of photovoltaic power generation can be greatly increased. It is also possible to interconnect the floor 13 installed on the upper part so that the column 61 can withstand wind pressure or external force well.

The reflective plate 23 is directly attached to the lower surface of the light-receiving photovoltaic panel 22 to form the integrated reflector panel 80. In this case, other sunlight can no longer be irradiated to the lower surface of the double-sided photovoltaic solar panel 22, but all the sunlight that has passed through the double-sided photovoltaic solar panel 22 is lower than the double-sided photovoltaic panel 22 without loss. There is an advantage that the cotton can be re-examined. In addition, since only one reflector-integrated panel 80 is installed without the need to separately install the reflector 23, the installation structure of the structure is simplified.

As shown in Fig. 8, among the sunlight irradiated on the upper surface of the double-sided photovoltaic solar panel 22, the sunlight passing through the double-sided photovoltaic panel 22 is lower than the double-sided photovoltaic panel 22. It is shown to construct a reflector integrated panel 80 by directly attaching the reflector 23 to the lower surface of the double-sided photovoltaic panel 22 so that it can be reflected back to the lower surface after passing through the surface. To form a holding gap 94 of an arbitrary scale between the photovoltaic panel 22 and the reflecting plate 23, a gap holding step 93 is added between the double-sided photovoltaic panel 22 and the reflecting plate 23. It is a feature. In this configuration, the angles of the incident light 91 and the reflected light 92 are diversified by the holding interval 94, and the solar light diffused and irradiated by the holding interval 94 exists, so that the double-sided photovoltaic panel 22 is more efficient. ) The lower surface can be irradiated with sunlight.

The reflector 23 applied to FIGS. 2 to 9 may be formed of the reflector 101 alone. The reflector 101 is made of a metal body that reflects well, a thin metal film, a silver-deposited mirror sheet, a mirror, or the like. However, in order to protect the reflector 101 or increase durability, it is proposed to add a protection device at the top or bottom. When snow accumulates on the reflector 101 constituting the reflector 23 or an object falls from the outside, such as hail, a protector 103 is added under the reflector 101 to increase durability, and the reflector is used as the combination 104 A characteristic feature is that the lower surface reflector 21 is formed by combining 101 and the protective body 103 to form a reflector 23. The protective body 103 is made of a material capable of withstanding an external force applied because it is to increase durability. In addition, in order to protect the upper surface of the reflector 101 that serves as a reflection in the reflector 23, a light-transmitting protective body 102 for transmitting sunlight is added to the top of the reflector 101 to form a light-transmitting protective body ( 102), the reflector 101, and the protector 103 are stacked in order and combined to be included in the scope of the present invention.

When the reflective plate 23 is configured as shown in FIGS. 8 to 11, sunlight cannot pass through the reflective plate 23. In FIG. 10, a partial light-transmitting reflector 121 in which a plurality of light-transmitting parts 122, which are portions of the reflector 101, are partially removed, so that some sunlight passes through the reflector 23, instead of the reflector 101 so that some sunlight passes through the reflector 23. It is characterized by replacing and configuring it. In this case, since sunlight can pass through the light transmitting part 122, solar light distribution in the upper and lower parts is smooth, and a more effective solar power generation facility configuration can be achieved. In particular, it can play a very effective role when applied to a levitation type photovoltaic power generation facility where solar irradiation is required under the reflector 23.
