Embodiment 1

[0022] Such as Figure 1-2 As shown, the double-glass photovoltaic module corner protector of the present invention includes two side walls 1 used to cover the two sides of the corner of the module, and a flat top wall 2 extends along the top edges 11 of the two side walls , the outer edge of the top wall 2 is inwardly concave arc; the bottom edge 12 of the two side walls forms an open free end, on the top wall 2, a glue overflow groove 3 is arranged along the top edge, the overflow glue groove The outer side of 3 is provided with glue-resisting ribs 4, and vent holes 5 are respectively provided on the two side walls. The included angle between the two side walls 1 is 85-90 degrees. In this embodiment, 89 degrees is selected. An included angle smaller than 90 degrees can form a certain clamping angle of the component. On the two side walls 1, respectively, Ribs 6 are provided.

Embodiment 2

[0024] Another aspect of the present invention provides a method for installing corner protectors for double-glass photovoltaic modules, including the following steps:

[0025] S1: Stack each layer of the double-glass module in order, which are cover glass, packaging material, battery string, packaging material, and back glass;

[0026] S2: Place the above-mentioned corner protectors on the four corners of the module. The top wall of the corner protectors is located above the back glass of the module. Use adhesive tape to fix the corner protectors on the module. The fixed tape avoids the row on the corner protectors. stomata 5;

[0027] S3: Each layer is laminated under the conventional process. During lamination, the packaging material layer (such as EVA layer) melts and flows to the gap between the corner protector and the glass and fills the overflow groove 3. After cooling, the corner protector is glued on On the four corners of the component, that is: the lamination proc...

Abstract

A dual-glass protection corner for a photovoltaic assembly comprises two side walls (1) wrapping two edges of an assembly corner. A flat top wall (2) extends out along the top edges (11) of the two side walls (1). An opening free end is formed at the bottom edges (12) of the two side walls (1). An excessive glue groove (3) is disposed on a top wall (2) along the top edge (11). A glue blocking arris (4) is disposed outside the excessive glue groove. An exhaust hole (5) is formed in each of the two side walls. In the dual-glass protection corner for a photovoltaic assembly, the mounting of the protection corner is completed when the assembly is laminated, and accordingly the photovoltaic assembly can be effectively protected and is prevented from being damaged due to collision, and the scrap rate of the assembly is reduced; the mounting process of the protection corner is simplified, and production costs are reduced.

Description

technical field [0001] The invention relates to a corner protector for a photovoltaic module, in particular to a method for installing a corner protector for a double-glass photovoltaic module, and belongs to the technical field of solar photovoltaic modules. Background technique [0002] As the name suggests, double-glass photovoltaic modules are made of glass for both the cover and the back, which can be directly used as building materials, and have higher safety performance such as impact resistance than ordinary photovoltaic modules. They are one of the common types of photovoltaic modules. The structure of a double-glass photovoltaic module generally includes sequentially stacked cover glass, encapsulation material, battery string, encapsulation material, and back glass. The above-mentioned layers of materials are laminated and other processes to form a double-glass photovoltaic module. Since the double-glass module has no frame and uses tempered glass, if the corner of...
