Description

Automatic cleaning device and cleaning method of solar panel array {AUTOMATIC CLEANING APPARATUS OF SOLAR PANEL ARRAY AND CLEANING METHOD THEREOF}

The present invention relates to an automatic cleaning device and a cleaning method for a photovoltaic panel array, and more specifically, elements that cover the surface of the photovoltaic panel as well as light (fine dust, snow cover in winter, pine dust, mites, pests) Or Nalfly, etc.), it is possible to quickly clean without damaging the solar panel in a non-contact manner with the solar panel, and quickly remove the snow on the surface of the solar panel in advance with heating heating. , Air Blowing, Drying with heat, and automatic cleaning device and cleaning method of solar panel array that can secure maximum power generation time in the daylight hours when sunlight is irradiated even in winter.

In general, solar power is generated by using solar light without the help of a generator, and solar light is directly converted into electrical energy by using a solar panel to which a plurality of solar cells are attached.

The solar cell of the solar panel has a structure different from that of a chemical cell, and converts sunlight into electrical energy using a P-type semiconductor and an N-type semiconductor. That is, when sunlight enters a solar cell in which a P-type semiconductor and an N-type semiconductor are joined, holes and electrons are generated by the light energy of the sunlight, and the generated holes are toward the P-type semiconductor. The generated electrons move toward the N-type semiconductor to generate electrical energy.

Such photovoltaic power generation is to generate power by connecting a plurality of photovoltaic panels in series and in parallel, so that no pollution is generated, and the required number of photovoltaic panels can be installed at required locations to generate power of required capacity. There is an advantage of easy maintenance.

The photovoltaic panel is usually installed outdoors because of the direct sunlight. Therefore, the surface of the solar panel is likely to be contaminated due to wind, dust, rain or snow accumulation.

When the surface of the photovoltaic panel is contaminated, generation of solar power due to contaminants decreases, thereby reducing power generation efficiency. Therefore, the surface of the solar panel must be cleaned periodically or as needed.

However, large-scale photovoltaic power generation facilities have a plurality of solar panels installed in series and in parallel, ranging in size from tens to hundreds of meters, and it is not easy to clean the surface of solar panels at high places.

In addition, as snow or the like is covered on the surface of the photovoltaic panel in winter, it may interfere with photovoltaic power generation, and as the load of the photovoltaic panel increases due to snow load and wind load, it causes collapse of the photovoltaic structure and safety accident Of course, there is a problem that the photovoltaic power generation efficiency is significantly reduced due to the adhesion of fine dust and insect swarms during the winter season.

Therefore, in order to maximize the efficiency of photovoltaic generation, it is necessary to input regular maintenance personnel or cleaning equipment or cleaning personnel, and when the washing device is configured in large size or frequently contacted with the surface of the solar panel, the solar panel circuit and solar power The panel itself can cause cracks and breakage.

Solar power generation refers to a power generation method that converts sunlight into electricity. Solar power generation is divided into photovoltaic power generation, which directly converts sunlight into direct current electricity, and concentrated solar power generation, which collects sunlight using a lens or mirror and uses the heat to generate power. As semiconductor production technology develops and device development costs for photovoltaic power generation gradually decrease, photovoltaic power generation is more widely used.

Photovoltaic power generation is usually done using solar panels with multiple solar cells attached. A solar cell is a solid electric device that directly converts light to electricity using a photoelectric effect.

The solar cell can be used semi-permanently, and since it does not require heating like the solar heat concentration method, it is easy to maintain, making it the most popular method for the next generation alternative energy production technology.

The amount of solar radiation incident on the solar panel is, of course, the factor that has the greatest influence on the efficiency of solar power generation. However, a large amount of solar radiation does not necessarily increase the power generation efficiency of the solar cell.

Silicon solar cells, which currently occupy more than 90% of solar cells, are converted to some thermal energy in the process of converting light energy into electrical energy, and the heat generated at this time increases the temperature of the solar panel, thereby reducing power generation efficiency.

Therefore, when looking at the power generation of solar power plants, more power is produced in the fall or winter than in the summer when there is a lot of solar radiation. However, it is not easy to calculate the efficiency of photovoltaic power generation due to the large fluctuations in power generation depending on solar radiation and temperature.

It is also known that dust that accumulates on solar panels is one of the major factors that degrade power generation efficiency. Therefore, it can be considered that the cleaning and maintenance of the photovoltaic panels installed in the photovoltaic power generation business can improve the photovoltaic power generation efficiency.

This is to further increase the cleaning efficiency by configuring it to be added or subtracted.

On the other hand, Figure 7 is a block diagram illustrating an automatic cleaning method of the solar panel array of the present invention.

1, 3 and 7, the automatic cleaning method of the solar panel array of the present invention is a sensor (S) detecting the degree of contamination of the surface of the solar panel 11 (S110); Determining whether the degree of contamination of the surface of the solar panel 11 exceeds a predetermined degree of contamination based on the data value sensed by the sensor (S120); As a result of the determination, when the degree of contamination of the surface of the solar panel 11 exceeds a predetermined degree of contamination, the transmitter 142 transmits the surface contamination state of the solar panel 11 to the remote control tower A. Step (S130); Receiving a cleaning instruction directed by the control tower (A) and moving the cleaning head 140 to a cleaning position (S140); The control unit 141 of the cleaning head 140 may include cleaning while moving the cleaning head 140 in the longitudinal and transverse directions along the longitudinal and transverse linear motor guides 110 and 130 (S150); The sensor (S) monitors the degree of contamination of the surface of the solar panel 11, and based on the data value sensed by the sensor (S), the pollution level of the solar panel 11 is set to a predetermined pollution level. Checking whether it exceeds (S160); And, as a result of the inspection, when the degree of contamination of the surface of the solar panel 11 exceeds a predetermined degree of contamination, the cleaning head 140 is moved to continue cleaning, and the surface of the solar panel 11 When the degree of contamination does not exceed the predetermined degree of contamination, and includes the step of confirming the completion of cleaning and returning the cleaning head 140 to its original position (S170).

More specifically, describing the automatic cleaning method of the solar panel array of the present invention, first, in the first step (S110), the sensor (S) detects the degree of contamination of the surface of the solar panel (11).

The sensor (S) is to monitor the amount of snowfall around the photovoltaic complex, fine dust, rainfall, swarm of insects in real time, as well as to detect the degree of contamination on the surface of the solar panel (11). The determination of the degree of contamination may transmit light to the photovoltaic panel 11 to inspect the degree of transmission or to detect the degree of contamination on the surface of the photovoltaic panel 11 through a vision inspection.

In the second step (S120 ), it is determined whether the degree of surface contamination of the solar panel 11 exceeds a predetermined degree of contamination based on the data value sensed by the sensor S.

As a result of determination, when the degree of contamination of the surface of the photovoltaic panel 11 does not exceed a predetermined degree of contamination (when the pollution is low), cleaning is not performed because it does not interfere with photovoltaic power generation.

If, as a result of the determination, the degree of contamination of the surface of the solar panel 11 exceeds a predetermined degree of contamination (the contamination is high), the transmission unit 142 controls the contamination status of the surface of the solar panel 11 at a remote control tower. Transmit to (A) (3rd step, S130).

In the fourth step (S140 ), when the cleaning command is instructed by the control tower (A), the cleaning command 140 received by the control tower (A) is received and the cleaning head 140 is moved to the cleaning position.

In the fifth step (S150 ), the control unit 142 cleans while moving the cleaning head 140 in the longitudinal and transverse directions along the longitudinal and transverse linear motor guides 110 and 130.

In the operation of the cleaning head 140, first, the brush block 143 covers the surface of the photovoltaic panel 11 or removes foreign matter, and the brush roller 143b is resiliently frozen or frozen by the spring 143d. Remove foreign objects. As such, the brush roller 143b is elastically installed, and thus cleaning can be performed while preventing damage or damage to the solar panel 11 during the cleaning process.

In addition, the water jet block 144 washes foreign matters that cover or obscure the surface of the solar panel 11 using water (washing water), and the filter 144d removes foreign matter that may be in the water (washing water). It is preferable that foreign matter does not adhere to the surface of the solar panel 11.

In addition, the air blower block 145 is a blower for drying water (moisture) remaining on the surface of the solar panel 11 or melting ice and snow, and in the winter, the blower 145c sprays heated air at high pressure.

In addition, in the operation of the cleaning head 140, it is possible to determine the heating operation of the heating wire H and the cleaning head by sensing the snowfall amount and the temperature, and cleaning can be performed in a solar panel unit or a solar panel array unit, that is, a group unit. It is possible.

In addition, although not shown in the drawing, it is possible to automatically monitor in a remote location in real time through a closed camera (CCTV), and to issue a warning sound once after a cleaning operation, and then operate a warning light.

By sensing various amounts of snowfall, rainfall, and outside temperature, it is possible to deliver the operation or operation through an app or a messenger, and an IOT real-time monitoring system that operates when the operator approves the command is possible.

The cleaning control method of the present invention can be adjusted differently according to the installation location of the solar panel array, so that the system can be operated in a manual, semi-automatic, automatic, safe mode (automatic stop, off-off).

In the present invention, for example, when the snowfall amount is 1 cm or less, the snow can be removed using a brush and an air blower. When the snowfall amount is 1 to 5 cm or more, a hot wire is first operated at a sub-zero temperature to melt the snow while melting the snow. It can be used for smooth removal of snow, dry cleaning, cleanliness, and maintenance.

When the temperature is below room temperature, it is preferable to prohibit water cleaning (because the surface temperature of the solar panel due to wind volume and wind speed may freeze on the surface of the solar panel due to the possibility of descending below zero).

In the present invention, when the cleaning system and communication are on, manual or remote control is possible, and the control unit can be operated by remote or administrator mode, sensing.

Regarding the vertical height adjustment of the cleaning head, although not shown in the drawings in this embodiment, by adopting conventional vertical height adjustment means such as racks and pinions, the amount of snowfall, temperature, and illuminance at sunrise are sensed, and heating and heating operations are performed. It determines whether it is, optimizes the separation distance between the photovoltaic panel and the cleaning head (zero point adjustment: 2cm height), and automatically adjusts the cleaning head in the automatic mode.

After the cleaning head is completely moved from left to right, considering the width that can be swept up and down at a moving speed of 1 m (100 cm)/min of the cleaning head, the up and down movement width moves up and down at a distance of 20 cm to snow or ice or snow. It is desirable to remove,

The moving speed of the cleaning head is not limited to this, and may be changed according to installation conditions or design conditions.

The cleaning head can be moved from side to side, from side to side, zigzag up and down to clean snow and dust.

Semi-automatic/step-by-step ice removal, cleaning, and maintenance can be performed in a safe mode with automatic monitoring by a manager directly from a power plant, remote monitoring through remote monitoring, or real-time monitoring to maximize the sunshine area on a solar panel at sunrise.

After the cleaning is completed, the system is turned off, and when it is overheated (within 40° C.), the heater off, blowing, and sweeper (brush) can be operated to perform cleaning.

Then, in the sixth step (S60), the sensor S detects the degree of contamination of the surface of the solar panel 11 again, and based on the data value detected by the sensor S, the solar panel 11 ) Is checked again to see if the contamination level exceeds the preset contamination level.

If, as a result of the inspection, the degree of contamination of the surface of the solar panel 11 exceeds a predetermined degree of contamination, the cleaning is continued by moving the cleaning head 140.

If, when the degree of contamination of the surface of the solar panel 11 does not exceed a predetermined degree of contamination, the cleaning is confirmed and the cleaning head 140 is returned to its original position (Step 7, S170).

On the other hand, Figure 8 is a view showing before and after the surface cleaning of the solar panel, through the automatic cleaning method of the present invention, it can be confirmed that the surface of the solar panel after cleaning compared to the surface of the solar panel before cleaning.

As described above, according to the present invention, in terms of maintenance for long-term use of a photovoltaic panel in a photovoltaic panel array of a photovoltaic complex, elements that cover light as well as cleaning (fine dust, snow cover in winter) , By removing pine resin, ticks, pests, flyfly, etc.), it is possible to efficiently and quickly perform cleaning while extending the lifespan without damaging the solar panel in a non-contact manner with the solar panel. The snow can be removed quickly, and air blowing and dry drying can ensure maximum power generation time during the daylight hours when sunlight is being irradiated even in winter.

In addition, sufficient solar power generation time (3.6 hours in Korea) can be secured to maintain power transmission, ESS charging and discharging, and sufficient revenue generation according to solar power generation.

In addition, in the present invention, it is preferable to avoid damage such as scratches on the surface of the solar panel by preventing the cleaning head as well as the configuration driving the cleaning head from contacting the surface of the solar panel.

In addition, it is possible to optimize the sunshine area and derive the optimal power generation through real-time monitoring management for cleaning through remote control, and it is also possible to maintain the solar panels at low cost even in mountainous forests, places where personnel and equipment are difficult to access, and more It can contribute to efficient solar power generation.
