Solar power is a technology that generates electricity by converting the light energy of the sun. Since solar power is the primary condition for securing sunlight, it is advantageous to use geographical conditions such as desert or grassland.

Photovoltaic power generation system using water surface has the advantage that there are no obstacles to the environmental conditions of the water surface by installing a floating body on the idle water surface such as rivers, reservoirs, ponds. In addition, when the solar power system is installed on the water surface, the solar panel has a cooling effect due to the natural convection phenomenon occurring on the water surface, and thus there is an advantage in that power generation efficiency is increased. Ground photovoltaic power generation is required to be additional land construction, such as site construction, foundation work when installed on land, and has the disadvantage of causing deforestation, etc. in the process of developing outback or forest. On the other hand, sleep photovoltaic power generation is a very suitable power generation method for Korea, which has a narrow territory by utilizing idle sleep.

There is a problem that the oxygen dissolved in the water decreases due to the green algae phenomena and eutrophication in which the phytoplankton grows in large quantities due to the stagnant summer water. The surface solar system can solve green algae removal and fish breeding by blocking sunlight from the water surface, and can be expected to reduce greenhouse gases and reduce fine dust by replacing old nuclear power plants with eco-friendly energy production. Water photovoltaic power generation system convergence technology that applies renewable energy sources to water facilities is a versatile value-added technology using water resources. It is a field that can be developed as a future reservoir demonstration model that combines renewable energy, IT, and BT technologies by escaping the existing limited use of water resources. If this technology is commercialized, it will be a future growth engine for eco-friendly water resources.

Recently, a system that can adjust the angle of the photovoltaic module by tracking the position of the solar cell according to the movement of the sun has been proposed, but there are problems that the production cost increases and maintenance is difficult because there are many necessary components such as the length adjusting module and the rotating module. .

In addition, the solar floating system is exposed directly to rivers and reservoirs when the worker climbs to the floating part for maintenance, and thus accidents may occur due to moisture, and components may be caused by bacteria growing in a humid environment. There is a problem that they are easy to corrode and the expiration date is shortened.

Experimental Example 3

In order to confirm the antimicrobial effect of the antimicrobial coating layer according to the present invention, the bacteria detection experiment of the antimicrobial coating layer composition (Example, Comparative Example 1, Comparative Example 2, Comparative Example 3) prepared by the above process was performed. The bacteria detection test was performed on a sterile workbench, and a dry film medium for Staphylococcus aureus was used.

First, 9 mL of sterile water was added to 1 g of the antimicrobial coating layer composition to make a 10-fold dilution solution evenly mixed using a homogenizer. Transfer the sample dilution solution to the sterile test tube and inoculate S. aureus to 3.0 × 10 ² CFU / mL concentration and mix using Voltex Mixer. Inoculate 1 mL of the finished sample solution into the dry film medium, transfer to an incubator, and incubate at 35 ° C. for 48 hours. After 48 hours, the number of colonies formed on the dry film medium was read to calculate the rate of change of the number of bacteria. The results are shown in Table 4 below.

As described above, in Comparative Example 1, although the concentration was lower than the inoculated bacterial concentration, Staphylococcus aureus remained, and in Example, Comparative Example 2 and Comparative Example 3, the bacteria were almost removed. However, in the case of Comparative Example 2, the amount of the antimicrobial material added during the film production was not uniformly mixed and the surface of the film was roughly prepared, and thus it was not suitable for application. There is a problem that is not uniformly melted during the processing of some of the antimicrobial coating layer. Therefore, the antimicrobial coating layer according to the present invention is suitable for application to the buoyancy body and exhibits an antimicrobial effect.
