BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a solar-

[0001] The present invention relates to a solar-powered photovoltaic device capable of adjusting the angle of a solar power module according to the altitude of the sun. More specifically, the solar- The present invention relates to a solar-powered photovoltaic power generator capable of improving the light-collecting efficiency of sunlight and capable of adjusting the angle in the vertical direction according to the altitude of the sun,

In general, solar battery is a photovoltaic cell that converts solar energy into electric energy. Its applications are electric clocks, radios, unmanned lighthouses, unmanned repeaters, buoys, .

In addition, houses for solar heating, fog alarms that alert the driver when fog is on the road, and airborne obstacles on structures such as power towers are also being used as solar cell applications.

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, a technique for installing a device for photovoltaic power generation in a waterfront has been developed. Such a photovoltaic power generation device can not stably float on the water by adapting to the change of the water level. Therefore, it was necessary to develop a device capable of supporting stable development even when the water level changes.

Even if the PV system is floated on the water surface, it is important to fix the position and fix it so that it does not drift away with the flow of water, and development of such supporting technology has been a priority. Photovoltaic devices installed on the water surface should be fixed in position, but it was difficult to stably install them in domestic rivers or reservoirs where the height of the water changes remarkably according to the season.

When the solar power generator is installed on the water surface, it is difficult to control the angle of the solar panel according to the trajectory of the sun due to the situation where it is installed on the water.
