NOVELTY - The apparatus has a first unit (100a) that includes upper portion support profile that is positioned at the outermost area (A). A second unit (100b) includes lower portion support profile that is positioned at the inter-space (B) through solar panels. Multiple solar panels are installed at the lower side of the profile assembly, for supporting buoyancy element with profile assembly, so that the solar panels positioned on the sleep is supported. The weight and volume of the second unit and specific profile are different.    USE - Aquatic solar energy generating apparatus for generating electricity using fossil fuel such as petroleum by using sunlight, atomic power, hydraulic power and wind force.    ADVANTAGE - The stability of the solar energy generating apparatus is improved and the structural declination provided between units positioned in outside and inter space can be reduced. The installation fee can be decreased. The structural safety about the rear surface with the configuration of arranging the empty space with the interspace furnace can be secured. The service life reduction due to corrosion can be suppressed at the damp environment of the low water surface in which the melting zinc aluminum magnesium alloy plating steel tape is used as the material of the profile included in two units, so that the installation and maintenance management cost can be drastically reduced in the long term. The generation efficiency can be improved by delivering the heat generated in the back side of the solar panel in the environment of the high temperature, so that the damage on the solar panel with the simple facility using aluminum foil can be prevented. The heat through two column delivery plates can be delivered under the sleep, so that the heat generated in the back side of the solar panel can be widely diffused and the ambient temperature can be reduced effectively.
