Description

Functional support structure of solar power generation device {STRUCTURE FOR SUPPORTING SOLAR PHOTOVOLTAIC DEVICE}

An embodiment according to the concept of the present invention relates to a functional support structure of a photovoltaic device, and in particular, it is capable of selectively providing strong stiffness that is not inferior in strength at all even when compared to conventional ferrous metals, while carrying a much lighter weight. It relates to a functional support structure of a photovoltaic power generation device that can increase the convenience of construction while reducing the logistics cost according to.

Photovoltaic power generation is a technology that directly converts sunlight (light) into electric energy using solar cells without the help of ordinary generators. The device (or system) for solar power generation is generally composed of a solar cell, a storage battery, and a power converter. When sunlight is irradiated to a solar cell in which a P-type semiconductor and an N-type semiconductor are bonded together, holes and electrons are generated in the solar cell by the energy of the sunlight. At this time, holes gather toward the P-type semiconductor and electrons toward the N-type semiconductor, so when a potential difference occurs, current flows.

The advantage of the solar power generation device is that there is no pollution, it can generate electricity only as needed in the required place, and maintenance is easy. On the other hand, the installation site may be limited, and the initial investment cost is high. In particular, when installing a photovoltaic device, a structure (or structure) capable of supporting the photovoltaic device must be properly adopted and used.

This will be explained a little more. The supporting structure (or structure) of the solar power generation device must have a structure that can withstand the external conditions such as the load of the solar panel and the snow pressure or wind pressure that the solar panel receives, as well as a solid foundation. Must be supported. In particular, since the solar panel has a large area, snow pressure or wind pressure acts very large in the front-rear direction toward which the solar panel faces. Therefore, it is common that the pillars or frames constituting the supporting structure of the solar power generation device supporting the photovoltaic power generation device are made of metal, such as a steel frame or an iron frame, so as to have a large design load. In fact, all support structures of existing photovoltaic devices are made of metal. However, such ferrous metals are not only expensive in material cost, but also have to undergo a galvanizing process after processing such as holes to prevent corrosion, which inevitably is cumbersome to manufacture. In addition, ferrous metals made of steel frames or steel frames are heavy in weight, which inevitably increases the cost of logistics transported from the manufacturing plant to the site, and also poses many difficulties in construction work. Considering the fact that solar power generation devices are installed on a large scale, if the parts are heavy, there will be many difficulties in transportation and construction.

Therefore, in order to solve this problem, the applicant does not have to go through a galvanizing process to prevent corrosion, and manufactures a supporting structure such as a column or frame made of aluminum material that is easy to handle due to its light weight and reinforcement as necessary. I would like to propose a technology.

Therefore, the weight is much lighter than that of the previous structure, and it can provide strengths for transportation and handling.

At this time, the post 120, the rail unit girder 130a of the rail girder 130, and the aluminum alloy steel that is the material of the loose 170 of the solar panel mounting portion 160 is carbon (C) as shown in FIG. 0.05 to 0.06 parts by weight, silicon (Si) 0.38 to 0.40 parts by weight, manganese (Mn) 1.05 to 1.10 parts by weight, phosphorus (P) 0.03 to 0.04 parts by weight, sulfur (S) 0.004 to 0.005 parts by weight, chromium (Cr) ) 18.16 to 18.20 parts by weight, nickel (Ni) 8.06 to 8.07 parts by weight may contain components.

1 and 7, the brace 150 serves to reinforce the strength of the post 120 and the rail girder 130 by connecting both ends of the brace 150 to the post 120 and the rail girder 130. This is not necessarily the case, but the brace 150 may also be made of aluminum alloy steel. The brace 150 may be a b-shaped structure. Of course, there is no relationship even if the brace 150 is a U-shaped structure. Therefore, the scope of the present invention is not limited to the shape of the drawings.

The solar panel mounting unit 160 is connected to the rail girder 130 and serves to mount the solar panel 10 for solar power generation.
