Description

Field type salt-resistant solar power system {Sea resistant photovoltaic power system}

An embodiment according to the concept of the present invention relates to an open-field salt damage-resistant photovoltaic power generation system, and in particular, it is possible to increase the number of bolts used if necessary, so that the screw pile and bonding work can be easily performed, and thereby It relates to an open-field salt damage-resistant solar power generation system that can contribute to increasing structural strength due to the high wind speed due to the characteristics of the region.

Solar power generation is a technology that directly converts sunlight (light) into electrical energy using solar cells without the aid of a conventional generator. A device (or system) for such photovoltaic 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, 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.

The advantage of solar power generation devices is that there is no pollution, can generate only as much power as needed in the necessary places, and it is easy to maintain.

On the other hand, there is a disadvantage that the installation site may be limited and the initial investment cost is high. In particular, when installing a photovoltaic device, a structure (or structure) that can support the photovoltaic device should be appropriately adopted and used.

This will be explained in more detail. The support structure (or structure) of the photovoltaic device must have a structure that can withstand the load of the solar panel and the external air conditions such as the snow pressure or wind pressure that the solar panel receives, as well as being strong in the foundation. must be strongly supported.

In particular, since the solar panel has a large area, the tongue pressure or wind pressure is very large in the front-rear direction toward the solar panel. Therefore, it is common that a pole or frame constituting the support structure of the photovoltaic device supporting the photovoltaic device is made of a metal such as a steel frame or an iron frame so as to have a large design load. In fact, all of the supporting structures of the existing photovoltaic devices are made of iron and metal.

However, such ferrous metals are expensive and inevitably difficult to manufacture because they have to go through a galvanizing process after processing a hole or the like to prevent corrosion.

In addition, the weight of ferrous metal made of steel frame or iron frame is heavy, which inevitably increases the logistics cost of transporting it from the manufacturing plant to the site, and also causes many difficulties in construction work. Considering that the solar power generation device is installed on a large scale, if the parts are heavy, there will inevitably be many difficulties in transportation and construction.

Accordingly, in order to solve this problem, the present applicant does not have to go through a galvanizing process for corrosion prevention and is made of an aluminum material that is light in weight and easy to handle, such as a pillar or frame, and is reinforced if necessary. A technology has been proposed and a patent has been applied for, and is currently under review.

However, in the case of a salt sea area or an area with an agricultural photovoltaic power generation system (solar power plant), due to the nature of the area, the wind speed is high. In the sense that a suitable structure has not been developed, research and development for this is necessary.
