Description

{Photovoltaic Generator Using Building Structure}

The present invention relates to a photovoltaic power generation apparatus using a building structure, and more particularly, to a photovoltaic power generation apparatus using a building structure, Generating device.

Generally, energy is limited to fossil energy such as petroleum, coal and natural gas, and there is a problem that pollutants are discharged.

Therefore, it is important to develop alternative energy that can be used instead. Among them, solar power is the most attracted technology.

Power generation technology using such solar light is a principle that can easily obtain electric power by receiving light and converting it into electric energy. Therefore, it is a clean power generation technology that can convert pollution-free sunlight into electric energy indefinitely and pollution such as air pollution, noise, heat and vibration.

In addition, fuel transportation and maintenance of power generation facilities can have a semi-permanent lifetime which is almost unnecessary.

Technologies for using solar energy include solar cell technology, which converts solar energy into electrical energy through solar cells, mainly solar cells, and solar thermal technology, which uses solar heat directly through a collector.

A solar cell is a semiconductor compound device that converts solar energy directly into electricity, and is manufactured to a thickness of 0.2 to 0.5 mm. The structure of a solar cell is a p-n junction structure made of a p-type semiconductor impregnated with phosphorus such as phosphorus, arsenic, and antimony, in the case of a monocrystalline silicon solar cell.

When sunlight having an energy larger than the forbidden bandwidth of the p-n junction is incident on a solar cell constituted by the pn junction, an electromotive force is generated by a photoelectric effect, and a current flows when an external load is connected. Using this principle, solar cells can be connected in series and parallel to produce the electricity needed for industry.

A solar cell refers to a semiconductor unit device that converts solar energy into electricity. A solar panel refers to a power unit that is manufactured in a minimum area unit manufactured by considering the durability environment by electrically connecting a plurality of solar cells.

Since a solar cell does not have enough power for one cell, each cell must be connected in series or parallel. This state is referred to as a 'solar panel'.

Solar panels consist of back sheet, solar cell, ribbon and EVA glass. TPT (Tedlar / PET / Tedlar) type is widely used for the back sheet, and the ribbon is used as a flow path for the current. Therefore, the material coated with silver or tin lead is used for the copper.

Since the photovoltaic device often has a solar tracking function in order to efficiently receive sunlight and the solar tracking device has to rotate a large solar panel, it takes a lot of cost to manufacture a driving device for driving the solar panel There is a problem.

In addition, since it is required to maintain robustness against an external natural environment such as a typhoon, there is a problem that a large amount of electric power is consumed to drive a motor because the inertia of the structure is naturally.

In addition, solar power generation has a problem that a relatively large area is required because the energy conversion efficiency is low. That is, since a planar solar cell module having a structure in which solar cells are arranged in a matrix (rows and columns) on a plane is used, a large area is necessarily required to produce a large amount of electric power.

However, such an increase in area may limit installation sites and increase costs. In addition, the planar solar cell module may be easily damaged by rain, hail or wind, and there is also a problem that power efficiency varies greatly depending on the direction in which sunlight is irradiated.

On the other hand, a tracking type solar power generation apparatus that collects and collects sunlight can be divided into a uniaxial type and a biaxial type.

This is determined according to the driving axis of the motor to be used. The uniaxial type is a simple type that does not track the altitude of the sun by arranging the solar panels on the left and right sides of the central axis and rotating left and right about the central axis using a motor including a speed reducer Respectively.

This unilateral formula has the effect of reducing initial installation cost instead of giving up about 10% surplus power generated by tracing the low and high ground.

Of course, although it is possible to track the altitude manually by changing the altitude if necessary, it is difficult to improve the efficiency by manually adjusting the heavy equipment manually.

The twin screw shaft is installed on the shaft connected to the rotating motor or the decelerating device, and the motor is mounted on the rear part of the tracking device, It is composed of a structure that adjusts the altitude by pulling the solar cell fixing device.

These biaxial equations consist of a regulator under the shaft and an upper solar tracking sensor

However, in the above-described related arts, the proposed system and apparatus for using solar energy are complicated in various means for collecting light, and the manufacturing cost thereof is also excessive, requiring periodic maintenance, The reflector does not immediately respond to the phase change of the sun, and the output of the heat collecting device is reduced or the efficiency is low.

For example, the following Patent Document 1 discloses a 'photovoltaic power convergence assisting device'.

The solar photovoltaic power convergence assisting device according to the following patent document 1 includes a solar power generation unit including a support, a solar power generation module installed in the support and generating power using solar light, And an auxiliary condensing unit provided with a reflection plate for reflecting incident solar light to the solar cell module.

The following Patent Document 2 discloses a reflector for photovoltaic power generation and a photovoltaic power generation system having the same.

The reflector for solar power generation according to the following Patent Document 2 and the solar power generation system having the reflector for solar power generation according to Patent Document 2 are reflector plates used in a solar power generation system having a plurality of solar cell plates installed at an angle to each other, And at least one surface of the reflection plate is provided with a reflection surface for reflection of sunlight.
