Description

Multifunctional solar panel cleaning device {MULTI-FUNCTIONAL SOLAR PANEL CLEANING DEVICE}

The present invention relates to a multi-functional solar panel cleaning device, and more particularly, to a multi-functional solar panel cleaning device designed to be installed on a solar panel with low power generation efficiency and to clean foreign substances, such as dust.

In recent years, photovoltaic power generation technology to replace fossil fuels has been rapidly developed. Solar power generation is a technology to obtain electricity by condensing light on a solar light collecting panel and converting solar thermal energy into electrical energy. In general, for photovoltaic power generation, a photovoltaic collecting panel is installed in an outdoor sunny area with good light. Unwanted impurities contained in rainwater and the atmosphere naturally accumulate on the surface of the panel installed outside the building, and the impurities block the light that should enter the panel and reduce the light collection efficiency.

Therefore, in order to maintain the light collecting efficiency of the photovoltaic panel, panel cleaning should be performed periodically, but cleaning the photovoltaic panel by an operator has a problem in that labor costs are excessively spent and maintenance costs increase. In particular, in recent years, the above-mentioned problem is further highlighted as the solar panel cleaning is frequently required due to yellow dust, fine dust, and ultrafine dust.

In order to solve this problem, a robot device for cleaning, a water washing device, etc. have been developed and proposed, but there is a limit in that it is difficult to use in reality due to a complicated structure and a high unit cost. In addition, the conventional invention has a problem in that the unit cost of the device is improved due to the large consumption of various sensors, required power and parts according to securing the supply of water and automatic driving.

Accordingly, by simplifying the structure of the device, there is a need for the development of a solar power panel cleaning device that can secure productivity and economic effects to expand the versatility of use.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .
