Description

[0001] The present invention relates to a photovoltaic device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an aquarium photovoltaic power generation apparatus, and more particularly, to an aquatic photovoltaic power generation apparatus that can be installed in water such as rivers, lakes, reservoirs and dams.

A photovoltaic power generation apparatus is a device for converting solar light directly into electric energy, and is implemented by fixing a plurality of solar cell modules, each having a plurality of battery cells in series and in parallel, to a support. Such a photovoltaic power generation device is not considered to be a pollutant in the power generation process and is not considered to be exhausted.

Particularly, as the electricity production efficiency of the solar cell module has recently increased and the manufacturing cost has decreased, many commercial solar power generation complexes capable of generating power in the megawatt unit using hundreds to thousands of solar cell modules have been developed .

This solar power generation is proportional to the installation area of the power generation facility under the same sunshine condition, so it is important that the construction site of the power generation facility is very important. However, it is difficult to secure the sunshine, In order to solve the problems such as the controversy and the rising cost of construction due to land compensation costs, there have been increasing cases of building solar power generation facilities in water ponds, lakes, rivers and dams.

By installing a photovoltaic power generation facility on the water surface, which is an idle site, the solar PV power generation facility can effectively utilize the land by effectively utilizing the installation space. In terms of domestic water resources, the area of the top 10 rivers is 74,697 km2, of which 1% is used for photovoltaic power generation, there is a potential to build a capacity of 74GW. The 31 dams operated by the Korea Water Resources Corporation, Sihwa Lake, It is a field rich in development potential to be able to construct 4,170 MW photovoltaic power generation facility even if only 5% of shared water surface such as construction reservoir and municipal sludge is used.

In addition, since the reservoir water surface has a lower radiant heat than the ground, it is possible to prevent the conversion efficiency from being lowered due to the temperature rise of the solar cell module, which has an advantage of relatively higher power generation efficiency. There is an effect of purifying water which reduces eutrophication.

However, there is a risk that the facilities will not be fixed compared to land-based power generation facilities, and there is a risk of flooding due to waves or wagging, a threat of drifting by winds, Therefore, it is necessary to measure the weather conditions that cause flooding or drift, and to check the status of the power generation system based on the conventional land-based photovoltaic power generation monitoring and control system, and accordingly, a proper response system is needed.

Therefore, it is possible to easily and easily assemble and install the modules without affecting the reservoir environment, maintaining the stable state of the module assemblies even in a severe sleeping state, reducing the construction cost and shortening the construction period. There is a need for technology development that can save lives and solve the shortcomings.
