More specifically, the solar power system's angle is actively adjusted in response to the load applied to the solar panel by strong wind pressure or a large amount of snow. This relates to a solar power system that actively changes the angle according to snow load and wind pressure to prevent damage and to easily adjust the inclination angle of the solar panel to ensure the best solar power generation depending on the season.

It is composed of an optical panel.

이와 같이 태양광패널프레임이 고정된 각도로 설치된 경우 계절의 변화에 따른 태양광의 입사각에 대응하지 못하여 태양광발전 효율이 저하되는 문제가 제기되었다.In this way, when the solar panel frame is installed at a fixed angle, a problem has been raised that solar power generation efficiency is reduced because it cannot respond to the angle of incidence of sunlight according to seasonal changes.

그러나, 태양광모듈의 각도를 조절하기 위해서는 태양광모듈을 고정하고 있는 고정볼트를 풀어 태양광모듈의 기울어진 각도를 조절하고 다시 고정볼트를 조여야 하는 어려움으로 인해 대단위 태양광 단지의 경우 계절에 따른 발전효율이 변화하는 것을 인지하고 있으나 이를 변경하지 않고 있어 발전효율이 저하되는 문제점이 있다.However, in order to adjust the angle of the solar module, it is difficult to loosen the fixing bolt that secures the solar module, adjust the tilt angle of the solar module, and then tighten the fixing bolt again. In the case of large-scale solar power complexes, seasonal Although we are aware that power generation efficiency is changing, we are not changing it, so there is a problem that power generation efficiency is decreasing.

또한, 최근 이상 기후 현상으로 인해 자주 발생하는 강풍과 폭설로 인해 태양광패널에 가해지는 하중에 대해 태양광시스템이 능동적인 대응을 하지 못하여 쉽게 파손되는 문제가 발생하고 있다.In addition, due to the strong winds and heavy snow that frequently occur due to recent abnormal weather phenomena, solar power systems are unable to actively respond to the load applied to solar panels, causing the problem that they are easily damaged.

The solar panel consists of a load buffering means that elastically supports the panel frame 21 and an angle adjusting means that adjusts the inclination angle of the solar panel frame 21 according to the incident angle of the sun. In addition to buffering the load applied to the frame, it is laid down at a gentle angle to prevent damage to the sun and the system. Additionally, the angle adjustment means is wound on the winding reel 41 and one end is exposed to the sun. It consists of a wire 42 fixed to the optical panel frame 21 and a tension maintaining part 43 provided on the fixing frame 12 to maintain the tension of the wire 42, by adjusting the length of the wire 42.

한편 본 발명은 태양광패널프레임(21)을 하중완충수단 및 각도조절수단을 통해 태양광패널프레임(21)의 태양빛 입사각이 변경되게 설정함으로써 발전효율이 극대화 되게 실시할 수 있는 것이다.Meanwhile, the present invention can be implemented to maximize power generation efficiency by setting the solar panel frame 21 to change the angle of incidence of sunlight through a load buffering means and an angle adjusting means.

첨부된 도 6은 기상청 국가기후자료관리시스템에서 발표한 월별 태양광 패널의 기울기를 고정 경사각 12˚, 21˚, 30˚로 설정하여 월별 발전량의 표현한 도면으로 이를 참조하면 태양광 패널의 경사각은 1월 ~ 3월은 경사각을 30˚로 설정하였을 때 평균 발전량이 약 3.93KW로 발전효율이 가장 높고, 4월 ~ 9월은 경삭각을 12˚로 설정하였을 때 평균 발전량이 약 4.49KW로 가장 높으며, 10월 ~ 12월은 경사각을 30˚로 하였을 때 평균 발전량이 약 3.66KW로 가장 높은 것을 알 수 있습니다.The attached Figure 6 is a drawing expressing the monthly power generation by setting the monthly solar panel inclination announced by the Korea Meteorological Administration's National Climate Data Management System to fixed inclination angles of 12˚, 21˚, and 30˚. Referring to this, the inclination angle of the solar panel is 1. From March to March, when the inclination angle is set to 30°, the average power generation efficiency is the highest at about 3.93KW, and from April to September, when the inclination angle is set at 12°, the average power generation is the highest at about 4.49KW. , it can be seen that the average power generation is the highest at about 3.66KW from October to December when the inclination angle is set to 30 degrees.

따라서, 태양광패널의 발전 효율이 변화되는 3월과 4월 사이 및 9월과 10월 사이에 태양광모듈의 각도 변화가 이루어져야 발전량을 극대화 할 수 있어 각도조절수단을 통해 와이어(42)를 최대치로 감았을 때 최저 12˚ 및 와이어(42)를 최대치로 풀었을 때 태양광패널의 경사각 최고 고정 경사각 30˚를 설정하게 되면 태양광 발전이 최적으로 이루어지는 것입니다.Therefore, the angle of the solar module must be changed between March and April and September and October, when the power generation efficiency of the solar panel changes, to maximize power generation, so the wire 42 is adjusted to the maximum through the angle adjustment means. Optimal solar power generation is achieved by setting a minimum of 12˚ when wound and a maximum fixed tilt angle of 30˚ when the wire (42) is unwound to its maximum.

이때, 상기 태양광패널의 기울기 조절은 각도조절수단인 지주프레임(10)에 구비되어 길이조절을 위한 와이어(42)가 권취되는 권취릴(41)을 최대치로 풀어놓게 되면 하중완충수단을 구성하는 스프링(S)에 의해 태양광패널프레임(21)이 탄성에 의해 승강되어 태양광패널프레임(21)의 각도를 30˚로 조절하게 되는 것이다.At this time, the tilt adjustment of the solar panel is provided on the support frame 10, which is an angle adjustment means, and when the winding reel 41, on which the wire 42 for length adjustment is wound, is released to the maximum, it constitutes a load buffering means. The solar panel frame 21 is lifted and lowered by elasticity by the spring S, thereby adjusting the angle of the solar panel frame 21 to 30°.

또한, 상기 와이어(41)를 권취릴(41)에 최대한 권취하게 되면 하중완충수단을 구성하는 스프링(S)이 압축되며 완충간격조절봉(31)이 승강유도축부(33)를 통해 하강되어 태양광패널프레임(21)을 15˚로 하강시키게 되는 것이다.In addition, when the wire 41 is wound on the winding reel 41 as much as possible, the spring S constituting the load buffering means is compressed, and the buffer gap adjustment rod 31 is lowered through the lifting guide shaft portion 33. The optical panel frame 21 is lowered to 15°.

한편, 상기 하중완충수단은 강풍에 따른 풍압과 많은 적설량으로 하중이 가해질 경우 승강유도축부(33)에 삽입된 완충간격조절봉(31)이 스프링을 압축하며 하강하게 되어 태양광패널에 가해지는 압력에 대해 충격과 압력을 완화 할 수 있게 되는 것이다.Meanwhile, in the load buffering means, when a load is applied due to wind pressure caused by strong winds and a large amount of snow, the buffer gap adjustment rod 31 inserted into the lifting guide shaft portion 33 compresses the spring and lowers, thereby reducing the pressure applied to the solar panel. It is possible to relieve shock and pressure.

한편, 상기 하중완충수단이 풍압이나 적설에 의해 하강할 때 각도조절수단에 구비된 텐션유지부(43)는 탄성조절봉(43c)이 스프링(S)의 탄성으로 와이어(42)를 지지하게 되어 하중완충수단과 더불어 태양광패널프레임(21)을 견고히 지지할 수 있게 되는 것이다.On the other hand, when the load buffering means is lowered by wind pressure or snow, the tension holding part 43 provided in the angle adjusting means supports the wire 42 with the elasticity of the spring S by the elastic adjusting rod 43c. In addition to the load buffering means, the solar panel frame 21 can be firmly supported.

또한, 본 발명의 실시에 있어서, 고정프레임(12)에 형성된 가이드공(12a), 상기 가이드공(12a)의 상부측에 일정 간격으로 천공된 고정공(12b), 상기 고정공(12b)을 통해 회전지지구(33a)를 고정하는 고정핀(14) 및 상기 회전지지구(33a)는 일측으로 돌출된 체결바(33a-1)와, 상기 체결바(33a-1)에 천공되어 고정핀(14)이 끼워지는 체결공(33a-2)로 구성된 완충텐션조절부(34)를 더 구비하여 실시하게 되면 하중완충수단에 구비되는 텐션 강도를 이중으로 조절할 수 있게 되어 계절 변화에 따른 텐션조절 폭을 넓게 가질 수 있게 되어 풍압 및 적설량에 따른 완충효과가 증대되는 것이다.In addition, in the practice of the present invention, a guide hole (12a) formed in the fixing frame 12, a fixing hole (12b) drilled at regular intervals on the upper side of the guide hole (12a), and the fixing hole (12b) A fixing pin 14 that secures the rotation support member 33a through a fastening bar 33a-1 protruding to one side, and a fixing pin 14 perforated in the fastening bar 33a-1. If (14) is further provided with a buffer tension control unit (34) consisting of a fastening hole (33a-2) into which the load buffering means is inserted, the tension strength provided in the load buffer means can be double adjusted, allowing tension adjustment according to seasonal changes. By being able to have a wider width, the buffering effect due to wind pressure and snowfall is increased.
