BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water photovoltaic power generation structure, and more particularly, to a water photovoltaic power generation structure capable of facilitating installation and repair while securing structural safety.

In recent years, renewable energy has attracted much attention as an alternative to solve the problems of energy depletion and environmental pollution, along with the issue of renewable nuclear power plants. Typical examples are solar power generation and wind power generation.

In the case of wind power generation, there are not many places suitable for wind conditions, so solar power generation is attracting more attention than wind power generation. Solar power generation is a power generation system that converts solar light directly into electric energy using solar cells without the aid of generators. It consists of solar cells, batteries, and power conversion devices. When sunlight is supplied to a solar cell that is a junction of a p-type semiconductor and an n-type semiconductor, holes and electrons are generated in the solar cell due to the energy of the sun light. Is collected toward the N-type semiconductor, and the current flows when the entire position is generated.

Solar power is advantageous in that it can be developed only in the places where there is no pollution, but it is necessary to install solar power on the ground as well as on the rooftop of the building, Lt; / RTI >

As a result, aquatic solar power generation, which is constructed by installing photovoltaic power generation facilities on water such as reservoirs, freshwater lakes, and the sea, has emerged. Water solar power generation can utilize idle sites, and water is more efficient than installed on land because water lowers the temperature around the solar cell.
