Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an economical solar cell module fixing unit,

The present invention relates to an economical solar cell module fixing unit capable of reducing manufacturing cost, and more particularly, to a solar cell module fixing unit which is manufactured from a buoyancy member capable of floating on a water surface for fixing a solar cell module, And more particularly, to an economical solar cell module fixing unit that can easily and rigidly fix an installation structure and greatly reduce manufacturing cost and production cost.

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 that can float on a surface of a water surface such as a lake, and Korean Patent No. 10-1170777 Reference 2) discloses a solar power generator in which a power generating support is buoyant on the surface of a river, a lake, a reservoir, a sea, a dam and the like, and the power generating support is provided with power generating means for converting and storing light energy irradiated from the sun into electric energy, Power generation device.

However, conventional solar cell module fixtures including the Patent Documents 1 and 2 have a structure in which a plurality of solar cell modules are installed in one fixture, so that they are difficult to manufacture due to their large volume, are expensive, and are limited in handling and transportation However, there is a problem that it is difficult to process electric wiring, and there is no room for a person to move for maintenance, which makes it difficult to work.

In addition, the inventor of the present invention proposed a module-integrated buoyant body module for a solar photovoltaic module in which one solar cell module is installed in one buoyancy body as in Korean Patent No. 10-1339358 (Patent Document 3).

However, if the size of the solar cell module is large, the size of the buoyant body also increases. If the size of the buoyant body is large, the size of the mold for molding the bulky body becomes enormous and the manufacturing cost is high. There are a lot of restrictions and there is a problem that the material cost of the production is also large and the manufacturing cost is high and the handling is not easy.
