[0001] DESCRIPTION [0002] Sunlight power generation apparatus [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic power generation apparatus using an internal surface of a fresh water lake such as a soot dam. More particularly, the present invention relates to a photovoltaic power generation apparatus using a compressor, a pump, The present invention relates to a freshwater photovoltaic power generation system for constructing a solar photovoltaic power generating plant having an independent island structure by concentrically forming a main buoyant body and continuously mounting a solar module thereon.

Generally, solar battery is a photovoltaic cell that converts solar energy into electric energy. Its application fields are electric clock, radio, unmanned lighthouse, unmanned repeater, buoy, satellite, rocket, etc. It is used as a circle.

In addition, houses for solar heating, fog warning lights that alert the driver when fog is fogged on the road, and aircraft obstacles installed in structures such as power transmission towers are also being used as fields for the use of solar cells.

A solar cell used in such a field of application connects a cell (a cell, meaning one solar cell) and a cell to a necessary number of series-parallel connection, and a solar cell panel is manufactured. .

However, since the power can not be generated at night, it is necessary to construct a circuit to charge the battery once during the day to obtain the power continuously. Should be used.

In the conventional photovoltaic device, a solar cell panel in which solar cells are connected in series and in parallel as needed is fixed at an angle of about 35 degrees toward the south-east. This is to produce the maximum power by making the angle of incidence of sunlight and the solar panel perpendicular to the fixed state.

However, in Korea, solar altitude varies from 12 ° C to 58 ° C for each season, so that when the solar panel is fixed, the power efficiency is low and the efficiency is low compared to the investment cost.

In general, in order to generate solar power, a large number of solar panels are installed on a ground of several kilometers. However, there is not enough ground for installing a large number of solar panels.

The large, smooth earth has a high land price, which is difficult to buy for solar power generation, and it is difficult to find a sunny place.

Therefore, there is an attempt to install a photovoltaic device in the waterfront, but a device capable of generating photovoltaic power by varying the flow and height of the water surface is required, and the direction of the solar panel is changed along the trajectory of the sunlight, A method and structure were needed to increase the efficiency of photovoltaic power generation.

Therefore, conventionally, there is a purpose of using an empty water surface by installing a solar panel on a water pond without requiring a large site as in the case of Registration No. 10-1013339 (Announcement 2011.02.10), and the efficiency of solar power generation The solar panel can be rotated according to the sun's trajectory in order to increase the temperature of the water. In addition, when the solar panel is installed on the water table, not only does the solar photovoltaic device on the surface of the water drift away, In particular, in order to obtain a driving force that can be easily rotated about a column, it is necessary to provide a buoy fixing frame having a solar panel fixed thereon, A rotary type solar photovoltaic device is disclosed.

However, in the above-mentioned prior art, a shaft column is installed at the center and the assembly is rotatably installed around the shaft column. In this method, the shaft column is severely shaken by external environmental factors (e.g. wind, typhoon, etc.) And there was a problem that it was damaged in severe cases.

In addition, the prior art as described above has disadvantages in that it is difficult to expand the solar panel because the assembled product is rotatable on one shaft column.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a method of installing a compressor, a pump, and a high-voltage substation in a central plate member, In order to stabilize the solar power plant regardless of the external environmental factors by constructing the independent solar island power plant with the concentric circle, the main buoyant body is installed continuously and the solar modules are regularly placed thereon And it is an object of the present invention to provide a freshwater photovoltaic power generation apparatus capable of expanding a solar panel through extension of a base frame to increase the power generation capacity of the power plant as needed.
