[0043] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Reference Figure 1 , showing a schematic diagram of the structure of a monitoring system for dust deposition on the surface of a solar photovoltaic cell according to an embodiment of the present invention; Figure 1 As shown, the monitoring system 100 for dust deposition on the surface of solar photovoltaic cells may include:

[0045] The weighing module 110 is used to weigh the ultra-white glass 120 of the solar photovoltaic cell to obtain a target weight;

[0046] The solar radiation measuring module 130 is used to measure the first solar radiation intensity incident on the ultra-clear glass 120 and the second solar radiation intensity passing through the ultra-clear glass 120;

[0047] An anemometer 140, used to measure the current wind speed;

[0048] A wind protection device 150 is used to isolate the solar photovoltaic cell from the surrounding environment when the current wind speed meets the preset conditions;

[0049] The data processing and analysis system 160 is used to generate a dust deposition impact report based on the target weight, the first solar radiation intensity and the second solar radiation intensity.

[0050] In an embodiment of the present invention, a monitoring system 100 for dust deposition on the surface of a solar photovoltaic cell may be composed of a weighing module 110 , a solar radiation measuring module 130 , an anemometer 140 , a wind protection device 150 , and a data processing and analysis system 160 .

[0051] The weighing module 110 can be used to weigh the weight of the ultra-white glass 120 of the solar photovoltaic cell; specifically, when it is necessary to detect dust deposition on the surface of the solar photovoltaic cell, the weight of the ultra-white glass 120 can be weighed to obtain the target weight of the ultra-white glass 120 with dust deposition. Exemplarily, the precision of the weighing module 110 can be 0.01 mg, the range can be 200 g, and the weighing module 110 can be a high-precision balance, which is not limited in the embodiment of the present invention.

[0052] In addition, the weight of the ultra-white glass 120 of the solar photovoltaic cell may be weighed in advance to obtain the first weight of the ultra-white glass 120 without dust deposition.

[0053] When the weight of the dust on the ultra-white glass 120 needs to be determined, the difference between the target weight and the first weight may be calculated and used as the weight of the dust on the ultra-white glass 120 , which is not limited in this embodiment of the present invention.

[0054] In practical applications, ultra-white glass 120, also known as low-iron glass or colorless glass, is a special glass with high transparency. In photovoltaic cells (solar cells), ultra-white glass 120 is mainly used as the cover material of solar cell modules, and its functions include:

[0055] High light transmittance: Ultra-clear glass 120 has a very low iron content, which greatly reduces its absorption of visible light, thus providing higher light transmittance. High light transmittance means that more sunlight can penetrate the glass to reach the solar photovoltaic cells, improving the photoelectric conversion efficiency.

[0056] Protection: Ultra-clear glass 120 as a cover can protect solar photovoltaic cells from the influence of the external environment, such as physical damage such as wind, sand, rain, snow, hail, and chemical erosion such as ultraviolet rays and acid rain.

[0057] Weather resistance: Ultra-clear glass 120 generally has good weather resistance and corrosion resistance, and can maintain stable performance under various climatic conditions, thus extending the service life of photovoltaic modules.

[0058] Mechanical strength: Ultra-clear glass 120 has high mechanical strength and can withstand certain pressure and impact, ensuring the safety of photovoltaic modules during transportation and installation.

[0059] Aesthetics: Due to the high transparency and low color difference of ultra-clear glass 120, it can provide clearer and more realistic visual effects, making photovoltaic modules more beautiful in building-integrated applications.

[0060] Thermal performance: Ultra-clear glass 120 has a moderate thermal expansion coefficient and thermal conductivity, which helps control the operating temperature of photovoltaic modules and avoid performance degradation due to excessive temperature.

[0061] The solar radiation measurement module 130 in the monitoring system 100 for dust deposition on the surface of solar photovoltaic cells can be used to measure the first solar radiation intensity incident on the ultra-white glass 120 and the second solar radiation intensity passing through the ultra-white glass 120; for example, Figure 2a As shown: the solar radiation measuring module 130 can measure the radiation intensity of the sunlight incident on the ultra-white glass 120 to obtain a first solar radiation intensity; the solar radiation measuring module 130 can also measure the radiation intensity of the sunlight passing through the ultra-white glass 120 to obtain a second solar radiation intensity; the sunlight passing through the ultra-white glass 120 can irradiate the solar photovoltaic cells and generate electrical energy.

[0062] The anemometer 140 in the monitoring system 100 for dust deposition on the surface of solar photovoltaic cells can measure the wind speed of the environment in which the solar photovoltaic cells are located and output the current wind speed.

[0063] In one embodiment of the present invention, the anemometer 140 may be a cup anemometer. Exemplarily, the cup anemometer 140 may be composed of a vertical axis and three or four hemispherical or conical cups, which are symmetrically mounted around the axis. When wind blows, the cups rotate due to the wind, and the speed of rotation is proportional to the wind speed. The working principle of the cup anemometer 140 is based on the torque generated by the wind on the cup; due to the shape of the cup, the wind force will cause the cup to rotate in one direction, and the speed of rotation can be converted into a wind speed reading.

[0064] The monitoring system 100 for dust deposition on the surface of solar photovoltaic cells may further include a wind protection device 150, which may be a sealing cover; when it is necessary to monitor the dust deposition on the surface of solar photovoltaic cells, the solar photovoltaic cells may be isolated from the surrounding environment to prevent the wind in the environment from affecting the accuracy of the measurement.

[0065] Specifically, the wind protection device 150 can isolate the solar photovoltaic cell from the surrounding environment when it is detected that the current wind speed of the environment where the solar photovoltaic cell is located meets the preset condition; after isolating the solar photovoltaic cell from the surrounding environment, the dust deposition on the surface of the solar photovoltaic cell can be monitored. The preset condition can refer to the current wind speed being lower than a threshold value, and the threshold value can be set according to actual conditions, which is not limited in the embodiment of the present invention.

[0066] For example, after isolating the solar photovoltaic cell from the surrounding environment, the weight of the ultra-white glass 120 of the solar photovoltaic cell can be weighed by the weighing module 110 to obtain the target weight of the ultra-white glass 120 currently deposited with dust; in addition, the first solar radiation intensity incident on the ultra-white glass 120 and the second solar radiation intensity passing through the ultra-white glass 120 can also be measured by the solar radiation measurement module 130.

[0067] Next, the data processing and analysis system 160 can generate a dust deposition impact report based on the target weight, and the first solar radiation intensity and the second solar radiation intensity; the dust deposition impact report may include the weight of the dust currently deposited on the ultra-white glass 120, and the impact of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cells.

[0068] Specifically, the influence of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cell can be evaluated based on the difference between the first solar radiation intensity and the second solar radiation intensity; for example, if the difference is larger, the influence of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cell is larger; if the difference is smaller, the influence of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cell is smaller. Of course, the influence of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cell can also be evaluated in combination with other information, for example, the influence of the dust currently deposited on the ultra-white glass 120 on the power generation efficiency of the solar photovoltaic cell can be evaluated based on the voltage output by the solar photovoltaic cell. If the voltage output by the solar photovoltaic cell is low, it can be considered that the dust currently deposited on the ultra-white glass 120 has a greater influence on the power generation efficiency of the solar photovoltaic cell; if the voltage output by the solar photovoltaic cell is high, it can be considered that the dust currently deposited on the ultra-white glass 120 has a smaller influence on the power generation efficiency of the solar photovoltaic cell, and the embodiment of the present invention is not limited to this.

[0069] In the embodiment of the present invention, the monitoring system 100 for dust deposition on the surface of solar photovoltaic cells includes: a weighing module 110, which is used to weigh the weight of the ultra-white glass 120 of the solar photovoltaic cell to obtain a target weight; a solar radiation measurement module 130, which is used to measure the first solar radiation intensity incident on the ultra-white glass 120, and the second solar radiation intensity passing through the ultra-white glass 120; an anemometer 140, which is used to measure the current wind speed; a wind protection device 150, which is used to isolate the solar photovoltaic cell from the surrounding environment when the current wind speed meets the preset conditions; a data processing and analysis system 160, which is used to generate a dust deposition impact report based on the target weight, the first solar radiation intensity and the second solar radiation intensity. Through the embodiment of the present invention, the dust deposition of the solar photovoltaic cell can be accurately measured by isolating the solar photovoltaic cell from the environment.

[0070] Furthermore, through the embodiments of the present invention, the dust deposition on the surface of the solar photovoltaic cell can be monitored in real time and automatically, and the influence of dust on the light transmittance and power generation efficiency of the solar photovoltaic cell can be discovered in time, so that a scientific and reasonable cleaning plan can be formulated according to the monitored data to avoid unnecessary cleaning operations, thereby saving manpower and resource costs. Moreover, dust can be cleaned in time to ensure the cleanliness of the photovoltaic panel surface, maximize the use of solar radiation, and improve the photoelectric conversion efficiency.

[0071] In addition, through monitoring, the ultra-clear glass 120 can be cleaned in time to reduce the wear and corrosion of the surface of the solar photovoltaic cells by dust, thereby extending the service life of the solar photovoltaic cells. It can also avoid the degradation of solar photovoltaic cell performance and frequent failures caused by dust accumulation, thereby reducing maintenance and replacement costs.

[0072] In practical applications, long-term monitoring data can also provide a scientific basis for analyzing dust deposition patterns and environmental impacts, to assist photovoltaic power generation research.

[0073] And through effective dust monitoring and cleaning, we can ensure the efficient operation of solar photovoltaic cells, increase power generation and improve economic benefits. Scientific management and maintenance of solar photovoltaic cells can reduce unnecessary cleaning and maintenance costs and reduce overall operating costs. In addition, it can also improve the power generation efficiency of solar photovoltaic cells, reduce the use of traditional energy, reduce carbon emissions and promote environmental protection. And through precise cleaning and maintenance, we can reduce the use of water resources and detergents and save environmental resources.

[0074] In one embodiment of the present invention, the above-mentioned monitoring system 100 for dust deposition on the surface of solar photovoltaic cells may further include:

[0075] The data collection and transmission system 170 is used to collect the target weight output by the weighing module 110 and the first solar radiation intensity and the second solar radiation intensity output by the solar radiation measurement module 130, and transmit them to the data processing and analysis module.

[0076] In practical applications, the monitoring system 100 for dust deposition on the surface of solar photovoltaic cells may also include a data acquisition and transmission system 170; for example, Figure 2b As shown, the data processing and analysis system 160 can be set at a remote end, and the data collection and transmission system 170 can be used to collect data from solar photovoltaic cells and transmit the data to the remote data processing and analysis system 160 to achieve remote monitoring and management.

[0077] In some feasible embodiments, the data acquisition and transmission system 170 can be used to connect the solar photovoltaic cell and the data processing and analysis system 160; exemplarily, the data acquisition and transmission system 170 can be used to collect the target weight output by the weighing module 110 and the first solar radiation intensity and the second solar radiation intensity output by the solar radiation measurement module 130, and transmit the collected data to the data processing and analysis module.

[0078] In one embodiment of the present invention, the data processing and analysis system 160 is further configured to store the target weight and the first solar radiation intensity and the second solar radiation intensity in a preset database.

[0079] In some feasible embodiments, the data processing and analysis system 160 can also store the collected target weight and the first solar radiation intensity and the second solar radiation intensity in a preset database; the preset database can be set in a server or a cloud platform, and the embodiment of the present invention is not limited to this.

[0080] In one embodiment of the present invention, the data processing and analysis system 160 is further used to pre-process the target weight and the first solar radiation intensity and the second solar radiation intensity.

[0081] In some feasible embodiments, the data processing and analysis system 160 may also be used to pre-process the target weight and the first solar radiation intensity and the second solar radiation intensity.

[0082] As an example, the preprocessing includes at least one of the following processing methods:

[0083] Data cleaning, data correction, and data format conversion.

[0084] Data cleaning can refer to identifying and correcting or deleting erroneous, incomplete, inaccurate or irrelevant data items in a data set. This process can include: removing duplicate records, filling missing values, correcting format errors, identifying and handling abnormal values ​​or outliers, unifying terminology or coding, etc.

[0085] Data correction refers to the precise modification of data to ensure its accuracy. This can involve: manually checking and correcting errors, using algorithms or rules to automatically identify and correct errors, comparing with the original data source or reference data, etc.

[0086] Data format conversion refers to converting data from one format to another for storage, processing or analysis. This can include: converting data from one file format to another, changing the encoding method of data, adjusting the structure of data, converting data types, etc.

[0087] In one embodiment of the present invention, the data processing and analysis system 160 is also used to obtain the output voltage and temperature of the solar photovoltaic cell;

[0088] The data processing and analysis system 160 is used to determine the amount of dust deposition based on the target weight; to determine the transmittance and attenuation rate of the ultra-white glass 120 based on the first solar radiation intensity and the second solar radiation intensity; and to generate a dust deposition impact report based on the dust deposition amount, transmittance, attenuation rate, and the output voltage and temperature of the solar photovoltaic cell.

[0089] In some feasible embodiments, the data acquisition and transmission system 170 can also collect the output voltage and temperature of the solar photovoltaic cell and transmit them to the data processing and analysis system 160. Specifically, the data acquisition and transmission system 170 can collect the output voltage and temperature of the solar photovoltaic cell before and after the wind protection device 150 isolates the solar photovoltaic cell from the surrounding environment.

[0090] After acquiring the output voltage and temperature of the solar photovoltaic cell, the data processing and analysis system 160 can determine the dust deposition amount according to the target weight.

[0091] In addition, the data processing and analysis system 160 can also determine the light transmittance of the ultra-white glass 120 and the attenuation rate of the light passing through the ultra-white glass 120 according to the first solar radiation intensity and the second solar radiation intensity.

[0092] After determining the transmittance and attenuation rate, the data processing and analysis system 160 can generate a dust deposition impact report based on the dust deposition amount, transmittance, attenuation rate, and the output voltage and temperature of the solar photovoltaic cell. Specifically, the influence of the current dust deposition amount on the power generation efficiency of the solar photovoltaic cell can be determined based on the transmittance, attenuation rate, and the output voltage and temperature of the solar photovoltaic cell.

[0093] For example, in combination with the effect of temperature on the power generation efficiency of solar photovoltaic cells, the effect of the current dust deposition amount on the power generation efficiency of solar photovoltaic cells can be determined according to changes in transmittance, attenuation rate, and output voltage.

[0094] In one embodiment of the present invention, the data processing and analysis system 160 is also used to generate a dust deposition impact report based on the installation position of the ultra-white glass 120, the amount of dust deposition, transmittance, attenuation rate, and the output voltage and temperature of the solar photovoltaic cell.

[0095] In some feasible embodiments, a dust deposition impact report can also be generated in combination with the installation position of the ultra-white glass 120, so as to optimize the installation angle and position of the photovoltaic panel according to the monitoring data feedback, reduce dust accumulation, and improve the rationality of the system design.

[0096] Specifically, the data processing and analysis system 160 can generate a dust deposition impact report at the current installation position of the ultra-white glass 120 based on the dust deposition amount, transmittance, attenuation rate, and the output voltage and temperature of the solar photovoltaic cell. Based on the dust deposition impact report, the dust deposition rate at the current installation position of the ultra-white glass 120 can be determined. In combination with the installation position of the ultra-white glass 120, the dust deposition rate at different installation positions of the ultra-white glass 120 can be determined, thereby optimizing the installation angle and position of the photovoltaic panel, reducing dust accumulation, and improving the rationality of the system design.

[0097] In one embodiment of the present invention, the data processing and analysis system 160 is also used to inspect the weighing module 110 , the solar radiation measuring module 130 , the anemometer 140 , and the wind protection device 150 .

[0098] In some feasible embodiments, the data processing and analysis system 160 can also be used to inspect the weighing module 110, the solar radiation measurement module 130, the anemometer 140, and the wind protection device to check whether the various components in the dust deposition monitoring system 100 on the surface of the solar photovoltaic cells can operate normally.

[0099] Exemplarily, a weighing module 110, a solar radiation measuring module 130 and a cup anemometer 140 can be installed next to the solar photovoltaic cells, and each device must be securely installed; the weighing module 110, the solar radiation measuring module 130 and the cup anemometer 140 are connected to a data acquisition and transmission system 170.

[0100] After installing all equipment, you can perform initial system debugging and calibrate each device to ensure data accuracy.

[0101] Configure the data collection and transmission system 170 to ensure that the data can be transmitted to the server or cloud platform in real time.

[0102] After installation and configuration, you can start collecting various data in real time and transmit the data to the server or cloud platform for storage.

[0103] The data processing and analysis system 160 can regularly process and analyze the collected data, calculate the dust deposition amount, transmittance and attenuation rate, and generate a dust deposition impact report for analyzing the impact of dust deposition on the power generation efficiency of solar photovoltaic cells.

[0104] In addition, each module and data acquisition and transmission system can be regularly inspected and maintained to ensure long-term stable operation of the system.

[0105] For example, Figure 2c As shown, when the current wind speed does not meet the preset condition, the wind protection device 150 does not isolate the solar photovoltaic cell 180; when the current wind speed meets the preset condition, the solar photovoltaic cell 180 can be covered to isolate the solar photovoltaic cell 180 from the surrounding environment; after the isolation is completed, the dust deposition on the surface of the solar photovoltaic cell 180 is monitored (in order to more clearly show the isolation process, Figure 2c The isolated solar photovoltaic cell 180 can still be seen, but has actually been isolated by the wind protection device 150, and the solar photovoltaic cell 180 in the wind protection device 150 cannot be seen from the outside).

[0106] Reference Figure 3 , shows a flow chart of the steps of a method for monitoring dust deposition on the surface of a solar photovoltaic cell according to an embodiment of the present invention, which can be applied to the above system and can include the following steps:

[0107] Step 301: Obtain a target weight from a weighing module after weighing the ultra-white glass of the solar photovoltaic cell.

[0108] In practical applications, the data processing and analysis system can obtain the target weight obtained by weighing the ultra-white glass of the solar photovoltaic cell from the weighing module through the data acquisition and transmission system.

[0109] Step 302: Obtain, from a solar radiation measurement module, a measured first solar radiation intensity incident on the ultra-white glass and a second solar radiation intensity passing through the ultra-white glass.

[0110] In some feasible embodiments, the data processing and analysis system can also obtain the measured first solar radiation intensity incident on the ultra-white glass and the second solar radiation intensity passing through the ultra-white glass from the solar radiation measurement module through the data acquisition and transmission system.

[0111] Step 303: Generate a dust deposition impact report based on the target weight and the first solar radiation intensity and the second solar radiation intensity.

[0112] In practical applications, the data processing and analysis system can generate a dust deposition impact report based on the target weight, and the first solar radiation intensity and the second solar radiation intensity; the dust deposition impact report can include the weight of the dust currently deposited on the ultra-white glass, and the impact of the dust currently deposited on the ultra-white glass on the power generation efficiency of the solar photovoltaic cells.

[0113] In the embodiment of the present invention, the target weight obtained by weighing the weight of the ultra-white glass of the solar photovoltaic cell is obtained from the weighing module; the measured first solar radiation intensity incident on the ultra-white glass and the second solar radiation intensity passing through the ultra-white glass are obtained from the solar radiation measurement module; according to the target weight and the first solar radiation intensity and the second solar radiation intensity, a dust deposition impact report is generated. Through the embodiment of the present invention, the impact of dust on the light transmittance and power generation efficiency of the solar photovoltaic cell can be discovered in time, so that a scientific and reasonable cleaning plan can be formulated according to the monitored data to avoid unnecessary cleaning operations, thereby saving manpower and resource costs. In addition, dust can be cleaned in time to ensure the cleanliness of the photovoltaic panel surface, maximize the use of solar radiation, and improve the photoelectric conversion efficiency.
