Description

[0001] Solar power generator [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation device, and more particularly, to a solar power generation device capable of continuously and stably adjusting the angle of the solar power generation modules.

Since the amount of fossil energy that is widely used is limited, it is depleted and some pollutants are emitted sometime. Therefore, most countries are developing alternate energy that can be used instead.

There are many types of energy that can replace fossil energy, such as an aid to generate energy using a tide-only car, a wave to generate energy using waves, a wind force to generate energy using wind power, And geothermal energy that generates energy using the heat of the ground. There is solar energy that is the source of these energy.

Many of these alternative energy methods are being put to practical use, and solar energy is used for power generation and heating. The method of using solar energy is classified into a method using solar heat and a method using sunlight.

The method of using the solar heat is a method of heating and generating electricity by using water heated by the sun, and the method of using the sunlight is to generate electricity by using the sunlight, It is called photovoltaic power generation.

Such solar power generation uses infinite, pollution-free solar energy, so there is no need for fuel cost, no air pollution or waste generation, no mechanical vibration and no noise since the power generation part is a semiconductor device and the control part is an electronic part.

In addition, the solar cell has a life span of at least 20 years, easy to automate the power generation system, and can minimize the cost of operation and maintenance.

The minimum unit of such a solar cell is referred to as a cell. Actually, a solar cell is rarely used as a cell. The voltage required for practical use is several tens of volts (V) to several hundreds of volts (V) or more, whereas the voltage output from one cell is very small, about 0.5 volts (V) Capacity or in series or parallel connection.

In addition, when the solar cell is used outdoors, it is subjected to various environments. Therefore, in order to protect a large number of cells connected with a necessary unit capacity in a harsh environment, a solar cell module .

Since the solar cell module must be used in a large amount in order to obtain a certain electric power, there is a limitation in the installation place. In other words, there is no problem when the solar cell module is installed on the roof of a building or an outdoor facility, but when the solar cell module is installed in a multi-family house occupying a considerable number of houses, it is difficult to individually install the solar cell module. In addition, due to the characteristics of the solar power generation system, the solar cell module needs to be installed on the rooftop of a building, a roof, or a separate stand.

However, according to the structure of the solar light structure according to the related art, when the strong wind blows or a large impact is applied, the screw fixing the bracket is loosened or the bracket is bent, There is a problem that the frame structure is twisted and the frame is severely broken and the solar cell module is damaged.

In addition, although the power generation efficiency varies according to the angle of the sunlight, since the solar power generation system is of a fixed type, there is a problem in that the four seasons are distinct and the surrounding environment with high altitude difference can not be effectively treated.

In order to solve the above problems, Korean Patent Laid-Open No. 10-2010-0032501 discloses a solar cell module plate angle adjusting device, Korean Patent Laid-Open No. 10-2013-0006778 discloses a solar cell module holder, , Korean Patent No. 10-1035388 discloses a photovoltaic structure capable of adjusting the angle.

However, the solar cell module holder of Korean Patent Laid-open No. 10-2013-0006778 and Korean Patent No. 10-1035388 have the problem that the angle of the solar cell module must be manually operated by the operator.

Korean Patent Laid-Open No. 10-2010-0032501 discloses an apparatus for adjusting the angle of the solar cell module plate. The apparatus includes a motor and is capable of automatically rotating the base horizontal axis by a motor. However, There is a problem in that it is necessary to directly operate the worker as described above.

As described above, the solar track position tracking apparatus for tracking the position of the sunlight has a relatively complicated structure, and the angle or position fixing is not accurately performed.
