Description

Solar cell module fixture

The present invention relates to a photovoltaic cell module fixture, and more particularly, to manufacture a fixture for fixing a photovoltaic cell module as a buoyancy body that can rise from the surface, while minimizing the material required during molding of the cell module The installation structure is simple and can be fixed firmly, and can significantly reduce the manufacturing cost and production cost and at the same time to prevent the sinking of the solar cell module even when the buoyant body breaks.

In general, the method of using solar energy uses solar heat for heating and generating power using water warmed by the sun, and solar power for operating various machines and apparatuses with electricity by generating electricity using solar light. Separated by.

The method of using solar is called solar power generation. Solar power generation facilities are divided into independent solar power generation facilities and grid-connected solar power generation facilities.

Stand-alone photovoltaic facilities have a solar cell array (solar panel) composed of a plurality of solar cell modules composed of solar cells that generate power using solar light, a storage battery that stores electricity generated from the solar panel, and the sun. It consists of a power regulator that allows electricity generated in the panel to be stored in the battery or supplied to an external load at a constant level, and an inverter and an auxiliary generator for converting direct current supplied from the capacitor and the power regulator into alternating current.

Such solar power generation has a low energy density and requires a large installation area, and since installation places are limited, securing a space for installing solar panels may be a challenge of solar power generation.

As a method for securing the solar module installation area, it is possible to consider installing it on the surface of rivers, lakes, reservoirs, dams, etc., where the amount of sunshine is rich and the open area can be easily secured. 10-0936597 (Patent Document 1) has proposed a water-resistant solar stop panel device in which a solar cell panel is installed on an upper part of a solar cell frame that can float on an inner water surface such as a lake, and the like. Also, Korean Patent No. 10-1170777 (Patent) In Document 2), a power generation support is buoyant on the surface of a river, a lake, a reservoir, an ocean, a dam, and the like, and the power generation support is equipped with a power generation means for converting and storing light energy emitted from the sun into electrical energy. The generator was proposed.

However, the conventional sleep floating solar cell module fixtures, including Patent Documents 1 and 2, are structured by installing a plurality of solar cell modules in a single fixture, and thus are difficult to manufacture due to their large volume, and are expensive and have limitations in handling or transportation. In addition, there is a problem such as difficult to process the electrical wiring and difficult to work because there is no space for a person to move for maintenance.

In addition, the present inventor has proposed a water-based solar module integrated buoyancy body in which one solar cell module is installed in one buoyancy body as in Korean Patent Registration No. 10-1339358 (Patent Document 3).

However, when the photovoltaic cell module is large, the size of the buoyancy body is increased accordingly. If the buoyancy body size is large, the size of the mold for forming the mold is enormous, so that the manufacturing cost is high and the injection molding apparatus is also expensive. There is a problem that a device is required, there are many restrictions, and because a lot of materials for injection molding are required, the manufacturing cost is expensive and the handling is not easy.
