Generally, photovoltaic power generation is a power generation method that uses the principle that electricity flows through the movement of electrons generated when light energy is injected into a solar cell made of a semiconductor.

Such solar power generation uses solar energy provided for an infinite amount of time, so it does not incur fuel costs and does not cause pollution such as air pollution or waste generation.

However, it is pointed out that such solar power generation is limited by the fact that the initial investment cost and the power generation unit cost are high, and a wide installation area is required.

Accordingly, in recent years, a method of installing a photovoltaic device in a river or a lake has been attracting attention in order to solve the installation area problem.
