Description

태양전지 모듈Solar cell module
본 발명은 태양전지 모듈에 관한 것으로, 보다 상세하게는 설치가 간편하고, 이송을 하거나 사용하지 않을 때 쉽게 분리할 수 있는 태양전지 모듈에 관한 것이다.The present invention relates to a solar cell module, and more particularly, to a solar cell module that is easy to install and can be easily separated when transported or not in use.
일반적으로 태양전지 모듈은 셀과 셀의 전극 배선을 구리 리본으로 연결하고 백시트, EVA(Ethylene-Vinyl Acetate), 태양전지 셀, EVA(Ethylene-Vinyl Acetate), 커버 유리(cover glass)의 순서로 적층하여 압착시키는 단계와, 압착된 적층체의 가장자리를 알루미늄 프레임으로 마감하는 단계와, 뒷면에 상기 구리 리본을 출력 케이블에 결선하기 위한 접속함(junction box)을 설치하는 단계를 통해 완성된다.In general, a solar cell module connects the cell and the electrode wiring of the cell with a copper ribbon, in the order of a back sheet, EVA (Ethylene-Vinyl Acetate), solar cell, EVA (Ethylene-Vinyl Acetate), and cover glass. It is completed through the steps of laminating and crimping, finishing the edge of the crimped laminate with an aluminum frame, and installing a junction box for connecting the copper ribbon to the output cable on the back side.
이러한 방법으로 제작되는 태양전지 모듈은 접속함을 사용하기 때문에 배선과 출력 케이블의 길이가 길어지는 문제점이 있다. 또한, 정해진 프레임 내에 셀이 설치되기 때문에 출력 용량을 조절하기 어려운 문제점도 있고, 태양전지 모듈에 포함되는 각 부품의 분리가 용이하지 않아 태양전지 모듈을 사용하지 않거나 이송 시에 취급하기 불편한 문제점도 있다.Since the solar cell module manufactured in this way uses a junction box, there is a problem that the lengths of wiring and output cables are lengthened. In addition, there is a problem in that it is difficult to adjust the output capacity because the cells are installed in a predetermined frame, and there is a problem that the solar cell module is not used or is inconvenient to handle during transport because it is not easy to separate each component included in the solar cell module. .

상기 가이드(220) 내부에 형성된 배선(223)에 의해, 인접한 태양전지 모듈의 가이드(220)에 고정된 태양전지 셀(210)의 제 1 전극(213)과 전기적으로 상호 연결된다.The first electrode 213 of the solar cell 210 fixed to the guide 220 of the adjacent solar cell module is electrically interconnected by the wiring 223 formed inside the guide 220.
이상과 같이, 본 발명의 제 2 실시형태에 따른 태양전지 모듈(200)은, 태양전지 셀(210)의 제 1 전극(213)과 가이드(220)의 제 2 전극(222)을 단순히 플러그 인 방식으로 체결하는 공정을 통해 조립되고 분해되므로, 조립이 매우 간편하다. 또한, 설치된 태양전지 모듈(200)을 분해하여 이송하거나 보관하고자 할 경우, 단순히 제 1 전극(213)을 가이드(220)의 제 2 전극(222)으로부터 분해하면 되므로, 이송 및 보관도 종래 구조의 태양전지 모듈에 비해 현저하게 간소해진다.As described above, in the solar cell module 200 according to the second embodiment of the present invention, the first electrode 213 of the solar cell 210 and the second electrode 222 of the guide 220 are simply plugged in. As it is assembled and disassembled through the process of fastening in a manner, it is very easy to assemble. In addition, in the case of disassembling the installed solar cell module 200 to be transported or stored, simply disassemble the first electrode 213 from the second electrode 222 of the guide 220, so that transport and storage are also of a conventional structure. Compared to the solar cell module, it is remarkably simpler.
