Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0044] Unless otherwise defined, all technical and scientific ter...

Abstract

The invention relates to a photovoltaic imbrication assembly. The photovoltaic imbrication assembly comprises at least two battery strings which are connected in series or in parallel; each battery string comprises at least two sequentially stitch-welded multi-main grid battery pieces; a lengthways main grid is arranged at one side of the front side of each multi-main grid battery piece; a lengthways back electrode is arranged at one side of the backside; the lengthways main grids and the lengthways back electrodes are located at different sides of the multi-main grid battery pieces; multiple first transverse main grids and multiple second transverse main grids are arranged at the front sides of the multi-main grid battery pieces, and first multi-main grid welding strip is welded at each first transverse main grid; and multiple transverse back electrodes in pairs are also arranged at the backsides of the multi-main grid battery pieces, and each pair of the transverse back electrodes is respectively located at the two sides of the backside of each multi-main grid battery piece and is welded through each second multi-main grid welding strip. According to the photovoltaic imbrication assembly, disconnection of the battery strings cannot be resulted even one multi-main grid battery piece is subjected to subfissure or breakage.

Description

technical field [0001] The invention relates to the field of photovoltaic components, in particular to a photovoltaic shingled component. Background technique [0002] As a green new energy, solar energy has many advantages such as inexhaustible, clean and environmental protection. The size of the traditional monolithic photovoltaic cells is relatively large, generally polycrystalline 175.75mm x 175.75mm and single crystal 125mm x125mm. The collection current density of photovoltaic modules using this photovoltaic cell series connection method is not uniform, and the power loss of photoelectric conversion Large, power generation efficiency is affected. To this end, the traditional photovoltaic cells are cut into several small cells of small width, the front busbars and the back electrodes of two adjacent cell units are overlapped, and are welded through a conductive medium to form two adjacent cell units A plurality of battery cells are welded and shingled to form a batter...
