The utility model relates to an asymmetric high mechanical strength dual glass assembly, including positive glass, go up glued membrane, battery cluster, lower glued membrane and back of the body glass, positive glass with the thickness of back of the body glass is different, positive glass with the length width homogeneous phase of back of the body glass. The utility model increases the light transmittance of the positive glass by thinning the positive glass, thereby increasing the overall power of the assembly; the thickness of the thinned positive glass reduces the overall weight of the dual-glass assembly, so that the dual-glass assembly is easier to transport and install; the thickness that has attenuate positive glass has practiced thrift the cost promptly for dual glass assembly cost reduction makes the product more competitive, through inconsistent positive glass of thickness and back of the body glass combination strengthened dual glass assembly's mechanical strength, makes it can be applicable to more abominable environment.

Description

Asymmetric high mechanical strength dual glass assembly

Technical Field

The invention relates to the field of photovoltaics, in particular to an asymmetric high-mechanical-strength dual-glass assembly.

Background

Along with the development of photovoltaic industry, traditional backplate subassembly is replaced gradually to dual glass assembly's excellent performance, and excellent vapor permeation prevention and anti latent crack ability let dual glass become the new favorite in photovoltaic market, and for practicing thrift the cost dual glass mainstream version type now is positive glass 2mm + back of the body glass 2 mm.

As the size of the battery cells increases, the size of the module increases, resulting in higher and higher requirements on the mechanical strength of the module. However, the mechanical strength of the solar cell panel made of the glaze-coated ceramic glass which brings high power gain is obviously insufficient; or the frame needs to be additionally arranged, so that the cost is increased, and the competitiveness of the double-glazing glass is obviously reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the obvious not enough problem of mechanical strength of solar cell panel of glaze-plated ceramic glass preparation, the utility model provides an asymmetric high mechanical strength dual glass assembly, including positive glass, go up glued membrane, battery cluster, lower glued membrane and back of the body glass, its characterized in that: the front glass is different from the back glass in thickness, and the length and the width of the front glass are the same as those of the back glass.

Preferably, the thickness of the front glass is smaller than that of the back glass.

Further, the thickness of front glass is 1.6mm, the thickness of back glass is 2 mm.

Preferably, a glaze plating layer is arranged on one surface, facing the front glass, of the back glass. If the back glass is plated on the outer surface of the back glass, a series of problems such as scratch, falling and the like can occur.

Further, the front glass is embossed glass or float glass.

Preferably, the back glass is embossed glass or float glass.

Has the advantages that: the utility model increases the light transmittance of the positive glass by thinning the positive glass, thereby increasing the overall power of the assembly; the thickness of the thinned positive glass reduces the overall weight of the dual-glass assembly, so that the dual-glass assembly is easier to transport and install; the thickness that has attenuate positive glass has practiced thrift the cost promptly for dual glass assembly cost reduction makes the product more competitive, through inconsistent positive glass of thickness and back of the body glass combination strengthened dual glass assembly's mechanical strength, makes it can be applicable to more abominable environment.

Example 1

The utility model provides an asymmetric high mechanical strength dual glass assembly, includes positive glass 1, goes up glued membrane, battery cluster, lower glued membrane and back of the body glass 2, positive glass 1 with back of the body glass 2's thickness is different, positive glass 1 with back of the body glass 2's length width is all the same.

The thickness of the front glass 1 is smaller than that of the back glass 2. The thickness of front glass 1 is 1.6mm, the thickness of back glass 2 is 2 mm.

The back glass 2 is equipped with plating glaze layer 3 towards the one side of positive glass 1. If the back glass 2 is plated on the outer surface, a series of problems such as scratch, falling and the like can occur.

The front glass 1 is embossed glass or float glass.

The back glass 2 is embossed glass or float glass.

The experimental demonstration is as follows: 1. the dual-glass assembly mainly comprises the following materials: battery, encapsulation glued membrane, interconnection strip, busbar, terminal box, silica gel, 1.6 mm's positive glass 1, 2.0 mm's back glass 2.

2. Traditional symmetry dual glass assembly: battery, encapsulation glued membrane, interconnection strip, busbar, terminal box, silica gel, 2.0 mm's positive glass 1, 2.0 mm's back glass 2.

The front glass 1 with the thickness of 1.6mm and the back glass 2 with the thickness of 2mm in the invention are proved by experiments with the front glass 1 with the thickness of 2mm and the back glass 2 with the thickness of 2mm in the traditional symmetrical double-glass assembly:

the invention is obviously lighter than the traditional symmetrical double-glass assembly in terms of weight;

in terms of power, the light transmittance is increased due to the fact that the front glass 1 is thinned, and therefore the overall power of the assembly is improved;

from the mechanical strength, the invention improves the overall assembly mechanical strength due to the combination of the front glass 1 and the back glass 2 with inconsistent thickness.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
