Generally, the method of using solar energy is a method of using solar heat for heating and power generation by using water heated by the sun and a method of using solar light for operating various machines and apparatus by generating electricity using solar light .

Solar power generation is called solar power generation, and solar power generation facilities are classified into stand-alone solar power generation facilities and grid-connected solar power generation facilities.

The stand-alone photovoltaic power generation facility includes a solar cell array (solar panel) composed of a plurality of solar cell modules composed of solar cells that generate electricity using solar light, a storage battery for storing electricity generated from the solar panel, An electric power regulating device for allowing the electricity generated by the battery board to be stored in a battery at a predetermined level or supplied to an external load, and an inverter and an auxiliary power generator for converting the direct current supplied from the capacitor and the power regulating device into AC.

Such solar power generation requires a wide installation area due to low energy density, and since the installation site is limited, securing a space for installing solar panels is a difficult problem of solar power generation.

In order to secure the installation area of the solar module, it is possible to consider installing it on the surface of a river, a lake, a reservoir, a dam, etc. which can provide a large amount of sunshine and a wide open area easily. 10-0936597 (Patent Document 1) proposes an in-situ solar ceiling panel device in which a solar cell panel is installed on a solar cell frame floating on a water surface such as a lake, and Korean Patent No. 10-1170777 Patent Document 2) discloses a solar power generation system in which a power generation supporting body is buoyant on the surface of a river, a lake, a reservoir, a sea, a dam and the like, and the power generation supporting body is provided with a power generating means for converting and storing light energy irradiated from the sun into electric energy. A photovoltaic device has been proposed.

However, since the buoyancy means of Patent Documents 1 and 2 is composed of a single body, the manufacturing cost is very expensive compared to the mold for manufacturing (molding) the same, and the production capacity is limited due to the large size of the molding machine. And a large amount of molding material is consumed, which leads to waste of materials, which leads to a problem of low price competitiveness.
