Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a trapezoidal box cover type glazed photovoltaic component. Background Art

[0002] Photovoltaic double-glass modules are currently encapsulated by film, and the film and cells are protected by glass. Generally, the back glass is grid-glazed glass to increase the reflection of light and improve the power of the module. Glass encapsulation also creates new problems, because the light is obliquely incident on the module. After the light enters the module, some of the light is emitted from the module through the side glass, reducing the utilization rate of the light. Therefore, we must find ways to improve the utilization rate of light. In order to maximize the power, the front glass of the module should minimize the obstruction of the cell and reduce the reflection of light. Therefore, it is difficult to make changes to the front glass to increase the power, so other methods must be sought. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1 The utility model provides a trapezoidal box cover type glazed photovoltaic module, comprising:

[0024] Back glass 1;

[0025] The front glass 2, the peripheral surface of the front glass 2 is set as an inclined surface 3, and the four inclined surfaces 3 of the front glass 2 have the same slope, so that the cross-sectional area of ​​the front glass 2 gradually decreases from top to bottom;

[0026] A number of cells are arranged between the front glass 2 and the back glass 1;

[0027] Among them, a grid glaze layer is arranged on each of the four inclined surfaces 3 .

[0028] The glazed trapezoidal box-covered glass structure has a box-covered front glass 2 whose side is not vertical but inclined relative to the back glass 1, which can effectively reflect the light emitted from the side, improve the light utilization rate, and increase the component power.

[0029] The inclined surface 3 of the front glass 2 can be smaller than 12 mm, which is smaller than the distance between the components. The size of the front glass 2 can also be enlarged to be larger than the size of the back glass, leaving a distance for the oblique side.

[0030] Further,

[0031] A plurality of battery cells are arranged between the front glass 2 and the back glass 1 through film packaging;.

[0032] Furthermore, a grid glaze layer is provided on the back glass 1 .

[0033] Furthermore, it also includes:

[0034] A positioning frame 4, on which a plurality of partitions for loading battery cells are provided;

[0035] The positioning frame 4 is located between the front glass 2 and the back glass 1 .

[0036] Furthermore, a plurality of light-transmitting holes 5 are formed on the positioning frame 4 .

[0037] The light passes through the light-transmitting holes 5 and the grid glaze layer on the back glass 1 to reflect the sunlight onto the battery sheet, thereby improving the sunlight utilization rate of the photovoltaic module and increasing the power output of the photovoltaic module.

[0038] Furthermore, a plurality of parabolic curved grooves 6 are formed at equal intervals on the top surface of the front glass 2 .

[0039] Equally spaced raised parabolic grooves 6 are provided on the surface of the front glass 2 at positions corresponding to the silicon cells. When the weather conditions are bad and the light intensity is weak, the light incident on the front glass 2 can be focused by the parabolic grooves 6. After the light is focused at the focus of the parabolic grooves 6, it acts on the silicon cells to generate electricity, thereby enhancing the intensity of the incident light and increasing the amount of power generated.
