Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a photovoltaic component with high light transmittance and a component installation system. Background Art

[0002] BIPV (Biopter Photovoltaic) technology combines solar power generation with building materials. By integrating photovoltaic modules into buildings, they achieve the integration of architecture and energy. These BIPV modules not only generate photovoltaic power but also meet the architectural aesthetic, decorative, and energy-saving requirements. BIPV technology will play an increasingly important role in future architectural design and energy utilization, making a significant contribution to sustainable development.

[0003] In order to meet the demand for aesthetics in buildings, the use of colored BIPV photovoltaic modules has gradually become widespread. However, a single color on the entire surface often cannot meet all the needs of architectural shape and aesthetics. The colored BIPV photovoltaic modules currently on the market mainly use different colors to paint the module pattern splicing patterns, which are realized by glass printing. Although this solves the problem of architectural aesthetics, new problems have emerged: (1) There are many types of existing colored BIPV photovoltaic modules, and the production and installation costs are high and implementation is difficult; (2) The patterns on the existing colored BIPV photovoltaic modules are inconsistent with the battery positions in the module, which will cause partial shading of the battery. Because the module battery is a series structure, it will affect the overall power generation efficiency of a single module. There is also a hot spot safety problem. The output current of each module in the entire system is also inconsistent, which will cause current mismatch and module efficiency loss. Utility Model Content

[0004] The purpose of this utility model is to design a photovoltaic module with high light transmittance to address the problem of low power generation efficiency of existing color BIPV photovoltaic modules, which easily causes current mismatch and module efficiency loss. The photovoltaic module can enrich the color of the module and improve the aesthetics of the module without affecting the power generation efficiency of the module.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] The utility model designs a photovoltaic module with high light transmittance, which comprises: high light transmittance glass, upper packaging film, battery layer, lower packaging film and back glass stacked in sequence from top to bottom; the battery layer is composed of a number of battery cells connected in series;

[0007] A plurality of linear color patterns are provided on the light incident surface and / or light exit surface of the high-transmittance glass, and the plurality of color patterns may be connected or not connected, the color patterns are provided corresponding to the gaps between the battery cells, the width of the color patterns is not greater than the gaps between the battery cells, and the color and transmittance of the positions on the high-transmittance glass corresponding to the battery cells remain consistent.

[0008] Specifically, the substrate of the high light transmittance glass in the present invention can be made of ultra-white glass or single color light transmittance glass.

[0009] Furthermore, in a photovoltaic module with high light transmittance, some of the color-rendering patterns can be configured as continuous linear structures or discontinuous linear structures.

[0010] Furthermore, in a photovoltaic module with high light transmittance, the colors of several of the color-rendering patterns can be set to be the same or different.

[0011] Furthermore, in a photovoltaic module with high light transmittance, the color pattern is set by silk screen printing or printing.

[0012] Furthermore, a photovoltaic module with high light transmittance: the upper packaging film is a high light transmittance film.

[0013] Furthermore, a photovoltaic module with high light transmittance: the lower packaging film is made of black color-developing film, and the back glass is made of black color-developing glass.

[0014] Furthermore, a photovoltaic module with high light transmittance is provided: the lower packaging film is made of black color-developing film, and the back glass is made of high-transmittance glass.

[0015] Furthermore, a photovoltaic module with high light transmittance is provided: the lower packaging film is made of a high light transmittance film, and the back glass is made of black color-developing glass.

[0016] The utility model also provides a photovoltaic module installation system with high light transmittance, which includes several photovoltaic modules mentioned above;

[0017] A plurality of the photovoltaic modules are spliced ​​and installed in different directions, angles and quantities to form a photovoltaic module installation system, so that the photovoltaic module installation system as a whole displays different pattern effects, thereby enriching the diversity of the building.

[0018] Beneficial effects of the utility model:

[0019] (1) The photovoltaic module of the present invention is simple to install and easy to implement. At the same time, the high-transmittance glass of the present invention can be easily realized on a glass substrate by screen printing or printing, and its production cost is low. The high-transmittance photovoltaic module of the present invention utilizes the color-developing pattern at the gap between the cells to achieve a decorative effect without affecting the power generation efficiency of the module.

[0020] (2) The utility model proposes a high-transmittance photovoltaic module installation system, which is formed by splicing and installing high-transmittance photovoltaic modules in different directions, angles and quantities, so that the system can display different pattern effects, enriching the diversity of buildings, and the installation process is simple to operate and the investment cost is low.

[0021] (3) The high-transmittance glass of the present invention has the same color and transmittance as the battery power generation unit (cell), and a linear color pattern is set at the corresponding gap between the cells. The present invention meets the architectural design requirements without affecting the transmittance and electrical performance parameters of the battery power generation unit by setting a linear color pattern at the non-power generation position (cell gap), thereby ensuring the color pattern requirements while maximizing the power generation efficiency of the components, and contributing to the construction of zero-carbon buildings.
