Description

Technical Field

[0001] The utility model relates to a photovoltaic power generation device, in particular to a photovoltaic power generation device installed on a wall or a facade. Background Art

[0002] Photovoltaic power generation systems convert sunlight energy into electricity through photovoltaic modules. To achieve ideal power generation efficiency, the light-receiving surface of the photovoltaic module must be tilted at a certain angle to the horizontal, so that the light-receiving surface of the photovoltaic module is as perpendicular to the sunlight as possible. Building roofs are the most common locations for distributed photovoltaic power generation systems. With the development of the photovoltaic industry, the number of rooftops suitable for photovoltaic power generation systems has gradually decreased. Numerous building walls facing the sun, especially factory walls, have come into view. However, on building walls, photovoltaic modules installed at an angle will protrude too far from the wall. This not only affects the aesthetics but also brings installation difficulties, heavy wall loads, and many other problems. Therefore, it is difficult to achieve an ideal installation angle for photovoltaic modules. Most photovoltaic modules are installed vertically, close to the wall. This creates a large angle between the sunlight and the light-receiving surface of the photovoltaic module, resulting in low power generation efficiency. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a lightweight component wall photovoltaic power generation device, which can enable the photovoltaic components to be installed on the wall at a certain angle to improve the power generation efficiency, and the components protrude from the wall a small amount and are easy to install.

[0004] In order to solve the above technical problems, the utility model provides a lightweight component wall photovoltaic power generation device, including several photovoltaic components, wherein the photovoltaic components are long and lightweight components, and a support strip is adhered to the back of the lightweight component, and the two ends of the support strip extend out of the corresponding ends of the photovoltaic component respectively. Component support seats are provided at both ends of each photovoltaic component, and the two ends of the support strip on the photovoltaic component are respectively inserted into the corresponding component support seats. An angle α is provided between the light-receiving surface of the photovoltaic component and the horizontal plane. The component support seat is inserted into the corresponding vertical rail, and several photovoltaic components are arranged at intervals on the vertical rail along the up and down directions through the corresponding component support seats.

[0005] After adopting the above technical solution, the photovoltaic module has a lighter weight and is in the shape of an elongated strip. After being installed on the wall at a certain inclination angle α, the distance extending from the wall can be shorter. After being installed in intervals in the vertical direction, it will not cause a major change to the appearance of the wall and the building, and it is also more beautiful. The lighter photovoltaic module also reduces the labor intensity of the installation process. At the same time, since the photovoltaic module is installed on the wall at a certain inclination angle, it can achieve the optimal inclination angle of the installation site, maximize the comprehensive power generation, and greatly improve the power generation efficiency of the photovoltaic module. The lightweight module is supported by the support bar to ensure the rigidity of the photovoltaic module. During the installation process, after the vertical rails are installed on the wall, the photovoltaic module between the two vertical rails is inserted into the corresponding module support seat through the two ends of the support bar, and the two module support seats are then connected to the corresponding vertical rails. The installation process is convenient and quick.

[0006] In a preferred embodiment of the present invention, the aspect ratio a:b of the elongated lightweight module is 4:1 to 15:1. This embodiment allows for the arrangement of cells in one to two rows across the width of the lightweight module, compared to six rows across the width of conventional modules, ensuring a shorter extension from the wall.

[0007] In another preferred embodiment of the present invention, the lightweight module is a photovoltaic power generation module comprising a flexible panel, an upper EVA layer, crystalline silicon cells, a lower EVA layer, and a backsheet laminated and encapsulated. This embodiment eliminates the glass panel and frame found in conventional modules, resulting in an extremely light weight, minimal building load, and easy installation.

[0008] In another preferred embodiment of the present invention, the angle α between the light-receiving surface of the photovoltaic module and the horizontal plane is 40° to 70°. With this embodiment, the light-receiving surface of the photovoltaic module can have an ideal installation inclination angle. Selecting an appropriate inclination angle based on the installation site allows the light-receiving surface of the photovoltaic module to achieve optimal overall power generation efficiency throughout the year and throughout the day as the sun's position changes from morning to night.

[0009] In a further preferred embodiment of the present invention, two support strips are bonded to the back of the lightweight component, and the two support strips are spaced apart along the width direction of the lightweight component. With this embodiment, the lightweight component can be supported reliably and stably, ensuring its rigidity.

[0010] In another preferred embodiment of the present invention, the support bar is an aluminum alloy profile member with a square or rectangular tubular cross section. In this embodiment, the support bar with a square or rectangular tubular cross section has high bending resistance, and the aluminum alloy support bar is lightweight and relatively strong.

[0011] In another preferred embodiment of the present invention, the side of the module support base is triangular, and is provided with support bar clip grooves corresponding to the cross-sectional shape and size of the support bar. The number of support bar clip grooves is the same as the number of support bars on the photovoltaic module, and the ends of the support bars on the photovoltaic module are respectively inserted into the corresponding support bar clip grooves on the module support base. With this embodiment, the connection between the photovoltaic module and the module support base is convenient, and when the module support bases at both ends are stably installed, the photovoltaic module can be installed reliably.

[0012] In a further preferred embodiment of the present invention, the vertical rail comprises a mounting base, a front wall parallel to the mounting base, and side walls located to the left and right of the front wall. The front wall is provided with a plurality of T-shaped card slots spaced along its length, with the width of the upper portion of the T-shaped card slots corresponding to the spacing between the left and right side walls. In this embodiment, the vertical rail is hollow, and the T-shaped card slots facilitate the installation and connection of the component support base.

[0013] In another further preferred embodiment of the present invention, a card block is provided on the component support seat, the card block protruding from the mounting surface of the component support seat that contacts the vertical rail, the card block is connected to the mounting surface via a connecting portion, the width and height of the card block correspond to the width and height of the upper portion of the T-shaped card socket, the width of the connecting portion corresponds to the width of the lower portion of the T-shaped card socket, and the thickness of the connecting portion corresponds to the thickness of the front wall of the vertical rail. With this embodiment, the card block can pass through the upper portion of the T-shaped card socket on the vertical rail and enter the inner cavity of the vertical rail, and then the connecting portion of the component support seat is inserted into the lower portion of the T-shaped card socket. In this way, the component support seat is inserted into the lower portion of the T-shaped card socket on the vertical rail through the card block and the connecting portion and relies on its own weight. It is effectively limited in the upper and lower, left and right, and front and back directions.
