Abstract

The present invention relates to a floating photovoltaic apparatus which is easy to assemble and maintain by using multiple unit buoyancy bodies, and which has a mooring structure that is easy to maintain tension of anchor wires extended from the bottom of the water when moving up and down according to levels of water. Since the floating photovoltaic apparatus of the present invention has a simple connection-type structure in which multiple unit buoyancy bodies are combined via a buoyancy body connecting means, the floating photovoltaic apparatus can be easily assembled in an all-in-one form on the land abutting the water, thus shortening an installation and construction period. Also, the apparatus has the advantage of easy maintenance because it is easy to replace a broken buoyancy body. A floating unit of the floating photovoltaic apparatus is allowed to be deformed according to the coupling direction and number of multiple unit buoyancy bodies, so it is easy to expand and reduce a required water surface reflection space depending on surrounding environments. Moreover, as the mutual coupling force between multiple unit buoyancy bodies is improved in first and second directions by first and second reinforcing beams, the resistance to external forces such as strong winds or waves is increased, thereby enhancing durability.
