Description

The automatic cleaning equipment of solar panel}

The present invention relates to an automatic solar panel washer, and more particularly, to an automatic solar panel washer that is installed on a solar panel and configured to perform cleaning while moving, thereby eliminating the need for separate cleaning personnel and thus reducing labor. .

In general, methods using solar energy are largely divided into methods using solar heat and methods using sunlight. The method of using solar heat is to heat and generate power using water heated by the sun, and the method of using sunlight is to generate electricity using the light of the sun and to operate various machines or instruments with the generated electricity. Therefore, the latter is commonly referred to as photovoltaic power generation.

Among the above-mentioned methods of using solar energy, photovoltaic power generation generates electricity by using the photovoltaic effect. When solar light is irradiated on a photovoltaic panel, electromotive force is generated by electron-holes by light energy.

To this end, a solar cell for concentrating sunlight, a photovoltaic module that is an assembly of solar cells, and a solar array in which solar cells are regularly arranged are required. For example, when light is incident on a solar module from the outside, electrons in the conduction band of a p-type semiconductor are excited to the valence band by the incident light energy, and the electrons thus excited are One electron-hole pair (EHP) is formed inside the p-type semiconductor, and among the electron-hole pairs generated in this way, electrons are transferred to the n-type semiconductor by the electron field between the p-n junction. It goes over and supplies current to the outside.

On the other hand, unlike existing energy sources such as fossil fuels, photovoltaic power generation is a clean energy source that has no risk of greenhouse gas emissions, noise, environmental destruction, etc. that cause global warming, and there is no concern about depletion. In addition, unlike other wind power or seawater power generation facilities, photovoltaic power generation facilities have the advantage of being free to install and having low maintenance costs.

However, in the case of the most widely used silicon solar cell, when the temperature of the solar module rises, a 05% reduction in output occurs per 1°C. According to these characteristics, the output of solar power records the highest in spring and autumn, not in summer when the sun is the longest.

This temperature rise is a major cause of lowering the power generation efficiency of photovoltaic power generation.

In addition, such a photovoltaic module has a disadvantage that dirt can be easily accumulated on the solar panel due to meteorological phenomena such as yellow dust and bad weather. When dirt accumulates on the solar module, the light absorption rate of the solar module is significantly lowered, and as a result, 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 be lowered. In order to prevent deterioration in power generation efficiency due to such dirt, snow, rain, etc., it is necessary to periodically clean the solar module.

Accordingly, in recent years, there is a trend in which a lot of cleaning devices for solar panels are being developed to solve these problems. As a prior art, Korean Patent Publication No. 10-2021-0052140 'solar panel cleaner' is disclosed as a conventional cleaning device for solar panels, and the patent relates to a rod, a motor connected to the rear end of the rod, and the motor. Disclosed is a technology including a water supply hose including a brush connected and rotated by the motor, an inlet provided at a front end and into which a cleaning solution is injected, and a nozzle portion provided at a rear end and configured to spray the cleaning solution to the brush.

However, this requires a lot of cleaning manpower to clean the solar panels of a large-scale photovoltaic power generation facility, and there is a problem in that fatigue of the washing manpower accumulates due to repeated operations.

In addition, the conventional general solar panel cleaning apparatus configured as described above has a disadvantage that the cleaning time is too long as the scale of the solar power generation facility increases.

Therefore, the present invention has been proposed to improve such conventional problems, and an automatic solar panel washer that saves labor by eliminating the need for separate cleaning personnel by configuring the cleaning to proceed while being installed on the solar panel. It aims to provide

Therefore, only the washing adjustment unit 90 will be described in detail.

The washing adjustment unit 90 may check the state of foreign substances attached to the upper surface of the solar panel S to adjust the washing intensity. To this end, the washing adjustment unit 90 may include a detection sensor 91 and an automatic washing control unit 70 .

The detection sensor 91 is formed along the longitudinal direction on the outer surface of the housing, irradiates light onto the upper surface of the solar panel S, and determines the amount of reflected light returned according to the state of foreign substances accumulated on the upper surface of the solar panel S and time can be measured. The detection sensor 91 is most preferably formed to face the solar panel (S) in order to accurately measure the amount and time of the reflected light, but is not limited thereto.

The automatic washing adjustment unit 90 may determine the foreign matter state of the solar panel S through the detection sensor 91 and adjust the washing time. Specifically, the automatic washing adjustment unit 90 may adjust the washing time by receiving the amount and time of the reflected light from the detection sensor 91, comparing the received amount with a preset value, and determining the state of the foreign matter. If the amount of reflected light is small or the time is short, the automatic washing adjusting unit 90 determines that the foreign matter is large and adjusts the washing time to be long.

Here, the predetermined value may be a value for the amount and time of reflected light of the solar panel S when there is no foreign matter input by the user to the automatic washing adjustment unit 90 in advance.

That is, the automatic solar panel washer 1 according to the fourth embodiment of the present invention adjusts the washing time according to the state of the actual foreign matter through the automatic washing adjusting unit 90 to perform the washing operation, so that the solar panel S Foreign matter can be effectively removed.
