Accordingly, the solar panel (panel) was contaminated by exposure to various contaminants caused by meteorological phenomena such as yellow dust, fine dust, or bad weather. As a result, the amount of light absorption in the solar panel decreases and the power generation efficiency decreases. occurred.

It is known that when pollutants such as yellow dust or fine dust accumulate on the top surface of the solar panel while the solar module is normally operated in the solar power device, the amount of power generated by the solar power device is reduced by 20% to 30% or more. Accordingly, it is reported that the reduction in power generation is large during February to May, when there is a large influx of foreign yellow dust or fine dust.

As described above, in order to solve the reduction in power generation due to pollution of the solar panel, the solar panel is cleaned using a cleaning tool or a cleaning robot uniformly in a regular manner for a certain period of time to remove the contaminants accumulated on the solar panel. are doing

However, since the pollution level of the solar panel is different depending on the air quality and weather around the solar panel, the cleaning management method that regularly cleans the solar panel only for a uniformly fixed period, regardless of the pollution level of the solar panel as in the prior art There was a limit to improving the amount of power generation as the cleaning was carried out in a state where the pollution level of the air conditioner was not reflected at all.

Hereinafter, the technical features of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a solar panel pollution level measurement and cleaning management system according to Example 1 of the present invention.

Referring to FIG. 1 , the solar panel pollution measurement and cleaning management system according to Example 1 of the present invention uses the amount of sunlight incident on the solar panel 1 and the amount of power generated by the solar panel 1 to generate sunlight. By calculating the degree of pollution of the solar panel 1a and providing a cleaning time of the solar panel 1a, the solar panel 1 can be efficiently managed.

The photovoltaic panel 1 includes a plurality of photovoltaic panels 1a arranged in a grid form to independently generate power. In addition, the solar panel 1 is provided with a solar panel 1 that measures the amount of sunlight that is incident on the solar panel 1 .

The amount of sunlight measuring unit 11 is installed on one side of the corresponding solar panel 1 to more accurately measure the amount of input incident on the corresponding solar panel 1 to be measured, and is incident on the corresponding solar panel 1 . Measures the amount of sunlight to be transmitted to the power generation comparison unit 12 .

The power generation comparison unit 12 compares the generated power generation amount of the photovoltaic panel 1 and the reference power generation amount stored in a database (not shown) after receiving the production power generation amount and the reference power generation amount produced by the corresponding solar panel 1 . At this time, in the database, a reference amount of power generation according to each amount of sunlight in a normal operating state of the corresponding solar panel 1 is stored. In addition, the power generation comparison unit 12 may receive information on the amount of power generated by the solar panel 1 from any one of the inverter 3 , the connection panel 2 , or the distribution panel 4 .

Briefly describing the process of comparing the production power generation amount of the solar panel 1 and the reference power generation amount, the generation amount comparison unit 12 receives the information about the amount of sunlight measured by the amount of sunlight measuring unit 11, the received amount of sunlight information is transmitted to the database. The database transmits the reference generation amount in the amount of sunlight corresponding to the amount of sunlight transmitted from the generation amount comparison unit 12 to the generation amount comparison unit 12, and the generation amount comparison unit 12 transmits the reference generation amount transmitted from the database and the corresponding sunlight Compare the amount of power produced by the panel (1).

On the other hand, when the amount of generated power generation is smaller than the reference power generation amount, the power generation comparison unit 12 provides a value obtained by subtracting the generated power generation amount from the reference power generation amount, that is, a decrease in the power generation amount to the pollution degree calculation unit 13 .

The pollution level calculating unit 13 calculates the current pollution level of the solar panel 1 by comparing it with the first pollution level reference value using the reduced amount of power provided by the generation amount comparing unit 12 . At this time, in the database, the first pollution degree reference value corresponding to the decrease in the amount of power generation by a predetermined size or ratio in consideration of the power generation efficiency of the solar panel 1 is calculated in advance and stored and managed.

For example, the pollution level calculation unit 13 calculates the pollution level and divides each step from '1' to '5'. For example, when the amount of generated power produced by the corresponding solar panel 1 is reduced by 5% compared to the standard power generation amount stored in the database in a normal state, the pollution level is '5' level, and when 10% is reduced, '4' Step, 15% reduction, '3' step, 20% reduction, '2' step, and 25% or more reduction, can be divided and classified into step '1', respectively.

The cleaning time notification unit 14 notifies the manager terminal 15 that the cleaning time has arrived according to the level of pollution calculated by the pollution level calculator 13 . For example, if the cleaning time is set to the contamination level '3' and the contamination level calculated by the pollution level calculation unit 13 corresponds to the '3' stage, the cleaning time notification unit 14 indicates that the cleaning time has arrived. Recognize and provide to managers.

On the other hand, although the cleaning time notification unit 14 informs that the cleaning time has arrived to the manager terminal 15, for example, a portable terminal or computer, the manager does not clean the solar panel 1 In consideration of this, a warning generating unit 16 may be installed on one side of the solar panel 1 to continuously generate a warning sound and a warning light.

The warning generating unit 16 automatically generates a warning sound and a warning light when an event signal transmitted from the cleaning time notification unit 14, that is, a signal indicating that the cleaning time has arrived, is received. In addition, the warning sound and warning light of the warning generating unit 16 is directly moved to the solar panel 1 in which the warning generating unit 16 is installed, and then a switch (not shown) provided in the warning generating unit 16 is directly turned on. It is configured so that it can be stopped only by manipulating it by touch or pressing.

As such, in the solar panel pollution measurement and cleaning management system according to Example 1 of the present invention, the reference power generation corresponding to the amount of sunlight incident on the solar panel 1 and the amount of generated power produced by the solar panel 1 are compared And, based on this, by calculating the pollution degree of the solar panel 1, that is, the solar panel 1a, and providing a cleaning time of the solar panel 1a, the manager can efficiently manage the solar panel 1 can be provided for
