Embodiment Construction

[0027] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0028] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a photovoltaic module, comprising a plurality of battery sheets and a plurality of welding strips, wherein each battery sheet is provided with a main grid line and an installation hole, the installation hole is communicated with the main grid line, and the installation hole is positioned at the end of the main grid line; each welding strip comprises a first connecting beltand a second connecting belt, and a bending part is formed between the first connecting belt and the second connecting belt; the first connecting belt and the second connecting belt are respectively positioned in the main grid lines of the adjacent battery sheets, and the bending part is accommodated in the installation holes. Therefore, the occurrence of height difference between the adjacent battery sheets can be avoided, and the compression of the welding strips on the battery sheets under the action of external force can be further avoided, so that the generation of hidden cracks of the battery sheets is reduced, and the processing is facilitated. The invention also discloses a photovoltaic module processing method.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a photovoltaic module. Background technique [0002] At present, the cells of existing ordinary photovoltaic modules are welded into strings by a stringer. During the welding process, a gap of about 2mm will be maintained between the cells, and the welding ribbon connecting the cells is between the gaps. There will be a bend similar to a "Z" shape, which ensures that the cells are basically on the same plane. If the cells are too close to each other, the ribbon will not be easy to bend, and due to the existence of the ribbon, there is a certain height difference between the two cells. In the later stacking and lamination process, due to the external force Under the action, the edge between the two battery pieces will cause hidden cracks or even cracks due to the existence of the welding ribbon, which is inconvenient to process and has hidden dangers in use.
