Description

Assembled Floating Barge System for Photovoltaic Power Generating System

The present invention relates to a prefabricated floating structure for installing a photovoltaic generator on the surface of the water, and more particularly, to adapt to various environmental conditions, such as changes in the water level of the installation surface, wind, waves, etc. It is about a prefabricated floating structure that supports to maintain and maximizes photovoltaic power generation efficiency.

Recently, due to the implementation of environmental regulations such as the declaration of eco-friendly policies such as GHG reduction of countries around the world, and the global oil shock and the nuclear accident in Japan, the necessity of renewable energy from the existing energy supply system that depends on fossil fuel and nuclear power is needed. The emphasis on solar power is increasing.

Photovoltaic power generation requires a certain area of installation site that can receive sunlight, and it is easy to secure an installation site due to increased regulations due to indiscriminate forest damage, except when using existing buildings and other facilities. Alternatively, water-based photovoltaic power plants are alternatively installed in reservoirs or dam surfaces. The water-based solar power plant not only saves the site purchase cost because it uses idle water, but also has an excellent cooling effect compared to the above-mentioned photovoltaic facilities.

The conventional water-based photovoltaic device is, as shown in Patent Literature 1, the top plate on which the solar cell integrated the solar cell array is arranged in order to improve the photovoltaic power generation efficiency while overcoming environmental conditions such as region, season, time and sunshine In order to face this sun, a technique for adjusting the direction of the floating structure is proposed by installing a screw on the lower surface of the floating structure on which the upper plate is installed.

However, the conventional method of directly moving the floating structure to face the sun not only consumes a lot of power to operate the screw due to the large weight of the floating structure and the resistance of the floating structure portion under the water surface, but also the underwater floats interfere with the normal operation of the screw. There is a concern. In addition, there is no consideration of the means of coping with changes in the height of the water and the shaking of the floating structure due to the waves generated by the wind or the ship operation near the floating structure.
