Abstract
Description
The present invention relates to a facility for improving the efficiency of a photovoltaic power generation facility, and more particularly, to a facility for improving efficiency of a photovoltaic power generation facility for condensing moisture in air to form water droplets and collecting water droplets to collect cooling water.
Generally, the method of using solar energy is divided into a method using solar heat and a method using sunlight. The method of using solar heat is a method of heating and generating electricity by using water heated by the sun, and a method of using sunlight is a method of generating electricity by using sunlight, It is called solar power generation.
Among the above-mentioned methods, photovoltaic power generation is a photovoltaic effect in which a photovoltaic panel having n-type doping on a silicon crystal and pn-junction is irradiated with sunlight to generate an electromotive force due to the photovoltaic energy, To generate electricity.
For this purpose, a solar cell for collecting sunlight, a photovoltaic module as an aggregate of solar cells, and a solar array for uniformly arranging solar cells are required.
For example, when light is incident on the solar module from the outside, electrons in the conduction band of the p-type semiconductor are excited to the valence band by the incident light energy. One electron-hole pair (EHP) is formed inside the p-type semiconductor, and electrons in the electron-hole pair generated are transferred to the n-type semiconductor by an electric field existing between the pn junctions. It passes over and supplies current to the outside.
Unlike existing energy sources such as fossil raw materials, sunlight is a clean energy source that does not have the danger of global warming, such as greenhouse gas emissions, noise, environmental destruction, etc., and there is no fear of depletion. Unlike other types of wind and seawater, solar power generation facilities are free from installation and maintenance costs.
However, in the case of the most widely used silicon solar cell, when the temperature of the photovoltaic module is increased, a power reduction of 0.5% per 1 ° C occurs. According to these characteristics, the output of photovoltaic power is highest in spring and autumn, not the longest summer. Such a temperature rise is a major cause of deteriorating the power generation efficiency of the photovoltaic power generation.
In addition, such a solar module has disadvantages that dust can be easily accumulated on the solar panel due to weather phenomenon such as yellow dust and bad weather. When dirt accumulates on the solar module, the solar module's light absorption rate is significantly lowered, and therefore the power generation efficiency may also be lowered.
In addition, when rain or snow falls on the solar panel in winter, the power generation efficiency may decrease.
In order to prevent such deterioration of power generation efficiency due to dirt, snow, and rain, the efficiency improvement equipment (maintenance equipment) of photovoltaic power generation facilities is used.
In order to improve the efficiency of solar power generation facilities, the cooling module which cools the temperature of the solar module and the cleaning and snow removal of the dirt, snow, rain etc. accumulated on the solar panel, It functions to maintain the solar power generation facilities.
In the efficiency improvement facility of the above-described solar power generation facility, sufficient cooling water must be secured in order to maintain cooling and cleaning efficiency.

Here, the condensed portion may have a through-hole formed in the bottom surface of the punch bowl to discharge the water droplet to the drain portion.
In addition, the water collecting module may include: a condensation portion in which the base portion formed with the hydrophilic surface forms a valley, the protrusion formed with the hydrophobic surface forms an acid following the valley, and the valley and the mountain are repeatedly formed in one direction; And a drain portion installed at a lower portion of the condensation portion and guided to the hydrophilic surface of the condensation portion to collect the droplets flowing into the cavity and to drain the condensed water to the storage tank.

Due to the nature of the water that is difficult to combine with the water molecules, the water flows down from the surface well and the water surface is collected by the property that the hydrophilic surface bonds well with water.
The water droplets formed on the minor water surface are formed such that the inclination angle A1 of the minor water surface and the surface of the water droplet exceeds 90 degrees and the water droplets formed on the hydrophilic surface are formed such that the inclination angle A2 of the water surface and the water droplet surface is less than 90 degrees.
Therefore, when water droplets are formed on the hydrophobic surface of the protruding
Here, the hydrophilic surface may be formed by coating a hydrophilic material on the base or by surface treatment, and the hydrophobic surface may be formed by coating or surface-treating a hydrophobic material on the protrusions.
The hydrophilic material may include a polymer material including amine functional groups such as acrylic acid, acrylamide, maleic anhydride, ethyleneimine, oxazoline, and arylamine, The hydrophobic material may include ether, styrene, vinyl acid, vinyl alcohol, and the like.
