Description

A solar photoelectric glass curtain wall assembly

technical field

The utility model belongs to the field of solar photovoltaic and building materials, in particular to a solar photoelectric glass curtain wall component used for building curtain walls.

Background technique

Building-integrated photovoltaic (BIPV) is a dual-purpose product that combines the functions of solar power generation and building exterior walls, and integrates, designs and installs solar cell modules or component arrays on buildings. Solar photovoltaic glass curtain wall is a new type of photovoltaic glass curtain wall building material made by combining solar photovoltaic technology with architectural glass curtain wall materials by using the principle of solar photoelectric conversion. It is an integration of photovoltaic power generation and building materials, and is an advanced form of BIPV. The combination of photoelectric glass curtain wall, controller, battery and inverter can form an independent photovoltaic power generation system, which can supply power to building owners, and can also directly supply power to the grid through inverter; not only is the structure firm, soundproof, and beautify the building, but it is also energy-saving, environmentally friendly, and sustainable. Reduce work and management costs, can create direct economic benefits.

In the prior art, the solar photoelectric glass curtain wall assembly used for building curtain walls is mainly composed of a panel, an intermediate layer and a bottom plate. Photovoltaic panel; the photovoltaic panel is a battery array formed by combining several solar cells in series and in parallel. In order to meet the strength requirements of engineering design standards, the overall thickness of the photoelectric glass curtain wall assembly must reach more than 23mm. Due to the limitation of glass thickness and cost, the photoelectric glass curtain wall assembly in the prior art usually uses 10mm glass, 1.52mm sealant and Double-layer glass structure with 10mm glass; however, the thickness of the glass panel of this structure is 10mm. During use, the sunlight will be refracted by the glass panel and then irradiated on the solar cells, and part of the light will be reflected and refracted many times. Therefore, when the thickness of the glass panel is large, the refraction path of light is longer, so its actual light transmittance is difficult to reach more than 85%, which will greatly affect the power generation efficiency of the photovoltaic panel, resulting in poor use of the product.

Contents of the invention

The purpose of the utility model is to provide a solar photoelectric glass curtain wall assembly, which has good power generation efficiency.

In order to achieve the above object, the technical solution adopted by the utility model is: a solar photoelectric glass curtain wall assembly, including a panel, an intermediate layer and a bottom plate, the panel is high light transmittance glass, and the intermediate layer is a solar panel packaged with a photovoltaic panel.

In the above, the panel adopts high transmittance glass with a thickness less than or equal to 6mm, which greatly shortens the refraction and reflection path of light in the glass, reduces the loss of light, thereby improving the transmittance, thereby improving the power generation of the photovoltaic panel efficiency; in addition, in order to meet the strength requirements of the photoelectric glass curtain wall assembly, the base plate adopts a composite structure, which is composed of two layers of high light transmittance glass, so that the overall thickness is greater than or equal to 23mm; the high light transmittance glass can be low Iron tempered glass, ultra-clear glass or other high-transmittance glass with certain strength; the sealant can be ethylene-vinyl acetate polymer or fluorine-containing plastic film or other sealants.

The preferred technical solution is that the panel has a thickness of 6mm, and the bottom plate is composited with high-transmittance glass with a thickness of 8mm and 6mm respectively, and the two layers of high-transmittance glass are fixedly connected by a sealant, and the sealant layer The thickness of the middle layer and the middle layer are both 1.52mm.

In the above technical solution, the four corners of the solar photovoltaic glass curtain wall assembly are provided with positioning holes. This is designed to facilitate its installation.

Due to the use of the above technical solutions, the utility model has the following advantages compared with the prior art:

1. Since the panel of the present invention adopts high light transmittance glass with a thickness less than or equal to 6mm, the refraction and reflection paths of light in the glass are greatly shortened, the loss of light is reduced, and the light transmittance can be increased to more than 90%. Compared with the 10mm high light transmittance glass used in the prior art, the power generation efficiency of the solar photoelectric glass curtain wall assembly is increased by 5% to 10%.
