DETAILED DESCRIPTION

[0035] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. Furthermore, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are intended only to explain the embodiments of the present application and are not to be construed as limiting the present application.

[0036] With the increasing development of renewable energy technology, the application of photovoltaic technology in various fields has become more and more extensive. In the field of solar photovoltaic applications, photovoltaic awnings are widely used because they have the characteristics of blocking sunlight and generating electricity at the same time. In related technologies, photovoltaic awnings include photovoltaic modules, which are used to convert solar energy into electrical energy. Generally, since photovoltaic modules need to be in direct contact with the external environment during use, the photovoltaic modules are prone to a decrease in photoelectric conversion efficiency due to dust deposition or high temperature. In order to solve this problem, the embodiment of the present application provides a photovoltaic awning 100 ( Figure 1 As shown), control method of photovoltaic awning ( Figure 3 shown) and storage medium 300 ( Figure 8 shown).

[0037] See also Figure 1 The photovoltaic awning 100 of the embodiment of the present application includes a photovoltaic component 10 and a first spray component 20. The first spray component 20 is configured to be able to switch between a first mode and a second mode. In the first mode, the first spray component 20 is used to output a high-pressure water flow to clean the photovoltaic component 10; in the second mode, the first spray component 20 is used to output atomized water vapor to cool the photovoltaic component 10.

[0038] It should be understood that the photovoltaic assembly 10 is the collection of components within the photovoltaic awning 100 that convert solar energy into electricity. The photovoltaic assembly 10 is capable of converting solar energy into electricity, achieving sustainable energy utilization. The photovoltaic assembly 10 does not produce greenhouse gases such as carbon dioxide or pollutants during power generation, resulting in a minimal environmental impact. The photovoltaic assembly 10 helps reduce reliance on traditional energy sources, alleviating air pollution and climate change. The photovoltaic assembly 10 can be installed in a distributed manner using supporting components, such as on rooftops, on the ground, or on water surfaces, to fully utilize solar energy resources. This distributed layout helps reduce transmission losses and improves the stability and disaster resilience of the powered awning. The photovoltaic assembly 10 can be combined and expanded as needed, making it suitable for power-generating awnings of various sizes and requirements. In certain embodiments of the present application, the photovoltaic assembly 10 includes photovoltaic panels, which are used to convert solar energy into electricity. These panels can be various types of solar energy conversion devices, such as single-crystal silicon, polycrystalline silicon, or thin-film solar cells. Users can choose photovoltaic panels of varying efficiency and size based on their specific needs.

[0039] Furthermore, in some embodiments, the photovoltaic awning 100 also includes an energy storage component, which is electrically connected to the photovoltaic component 10. The energy storage component can store the electrical energy generated by the photovoltaic component 10 and can power loads such as household appliances and portable devices. The energy storage component and the photovoltaic component 10 can be electrically connected through a cable (such as a cable made of copper wire, aluminum wire or other conductive materials, etc.), or can be electrically connected through an intermediate device such as a junction box or a busbar. It should be noted that in some embodiments, the energy storage component can be a lithium-ion battery, a lead-acid battery or other type of rechargeable battery, or a device that can store and release electrical energy, such as a supercapacitor.

[0040] The first spray assembly 20 is a structure in the photovoltaic awning 100 for cleaning and cooling the photovoltaic assembly 10. The first spray assembly 20 removes dust, dirt and other impurities on the surface of the photovoltaic assembly 10 by spraying cleaning liquid onto the photovoltaic assembly 10, and at the same time uses the evaporation heat absorption effect of the liquid to reduce the temperature of the photovoltaic assembly 10, thereby not only improving the power generation efficiency of the photovoltaic assembly 10, but also reducing the possibility of high-temperature damage to the photovoltaic assembly 10, thereby extending the service life of the photovoltaic assembly 10.

[0041] It should be noted that clean liquids include, but are not limited to, clean water and mixtures of clean water and cleaning liquid. Clean water is a relative term; any water that is cleaner than what users would consider sewage is protected. For example, clean water can include municipal tap water, sewage filtered through a filter, or clean water from rivers, lakes, or oceans.

[0042] In certain embodiments of the present application, the first spray assembly 20 can switch between a first mode and a second mode. That is, the first spray assembly 20 can operate only in the first mode to clean the photovoltaic assembly 10; or the first spray assembly 20 can operate only in the second mode to cool the photovoltaic assembly 10. In addition, in other embodiments, the first spray assembly 20 can operate in the first mode and the second mode simultaneously to clean and cool the photovoltaic assembly 10.

[0043] It is understood that in the first mode, the high-pressure water flow output by the first spray assembly 20 can not only clean the photovoltaic assembly 10, but also cool the photovoltaic assembly 10 to a certain extent. In the embodiment of the present application, in the second mode, the use of atomized water vapor for cooling can not only ensure the cooling effect, but also save water and reduce resource consumption.

[0044] In the photovoltaic awning 100 of the embodiment of the present application, the first spray assembly 20 cooperates with the photovoltaic assembly 10 and is configured to be able to switch between a first mode and a second mode. In the first mode, the first spray assembly 20 is used to output a high-pressure water flow to clean the photovoltaic assembly 10; in the second mode, the first spray assembly 20 is used to output atomized water vapor to cool the photovoltaic assembly 10. Therefore, the setting of the first spray assembly 20 can, on the one hand, avoid dust deposition and cause the transmittance of the photovoltaic assembly 10 to decrease, thereby improving the photoelectric conversion efficiency of the photovoltaic assembly 10; on the other hand, it can avoid the performance degradation caused by overheating of the photovoltaic assembly 10, thereby improving the photoelectric conversion efficiency of the photovoltaic assembly 10; on the other hand, it can prevent the photovoltaic assembly 10 from being damaged by overheating, thereby extending the service life of the photovoltaic assembly 10 and improving the safety performance of the photovoltaic assembly 10.

[0045] The photovoltaic awning 100 is further described below with reference to the accompanying drawings.

[0046] See also Figure 1 In some embodiments, the first spray assembly 20 includes a spray pipe 21 and a nozzle 23 provided on the spray pipe 21. The nozzle 23 is connected to the spray pipe 21 and is configured to achieve the first mode and the second mode.

[0047] Specifically, in certain embodiments, during the operation of the first spray assembly 20, the cleaning liquid can be delivered to the nozzle 23 through the spray pipe 21. At this time, the nozzle 23 can spray the cleaning liquid onto the photovoltaic assembly 10 in the form of a high-pressure water flow or atomized water vapor. That is, in the first mode, the nozzle 23 can spray the cleaning liquid in the spray pipe 21 onto the photovoltaic assembly 10 in the form of a high-pressure water flow; in the second mode, the nozzle 23 can spray the cleaning liquid in the spray pipe 21 onto the photovoltaic assembly 10 in the form of atomized water vapor. Thus, the nozzle 23 can realize the first mode and the second mode, and enable the first spray assembly 20 to switch between the first mode and the second mode.

[0048] It should be noted that in some embodiments, the photovoltaic assembly 10 includes at least one. The spray pipe 21 is associated with each photovoltaic assembly 10 in a one-to-one relationship, or a one-to-many relationship, i.e., one spray pipe 21 corresponds to one photovoltaic assembly 10, or one spray pipe 21 corresponds to multiple photovoltaic assemblies 10. Furthermore, each photovoltaic assembly 10 includes at least one photovoltaic panel. The nozzles 23 are associated with each photovoltaic panel in a one-to-one relationship, a one-to-many relationship, or a many-to-one relationship, i.e., one nozzle 23 corresponds to one photovoltaic panel, one nozzle 23 corresponds to multiple photovoltaic panels, or multiple nozzles 23 correspond to one photovoltaic panel.

[0049] Furthermore, in some embodiments, the photovoltaic awning 100 further includes a water storage assembly 30 , and the water storage assembly 30 includes a water tank 31 , and the water tank 31 is used to provide cleaning liquid to the first spray assembly 20 .

[0050] Among them, the spray pipe 21 is connected to the water tank 31. For example, the spray pipe 21 can be connected to the water tank 31 through a pipeline. During the operation of the first spray component 20, the cleaning liquid in the water tank 31 can be transported to the nozzle 23 through the spray pipe 21, and sprayed to the photovoltaic component 10 through the nozzle 23 in the form of high-pressure water flow or atomized water vapor. That is, in the first mode, the nozzle 23 can spray the cleaning liquid in the spray pipe 21 to the photovoltaic component 10 in the form of high-pressure water flow; in the second mode, the nozzle 23 can spray the cleaning liquid in the spray pipe 21 to the photovoltaic component 10 in the form of atomized water vapor.

[0051] Specifically, in some embodiments, the water storage assembly 30 further includes a water pump connected to the spray pipe 21. The water pump is used to pump the cleaning liquid in the water storage tank 31 to the spray pipe 21. The water pump can increase the pressure of the cleaning liquid flowing into the spray pipe 21, thereby ensuring that the nozzle 23 can spray the cleaning liquid onto the photovoltaic assembly 10 in the form of a high-pressure water flow or atomized water vapor.

[0052] Furthermore, in some embodiments, the water storage component 30 also includes a collecting component 33 and a processing component 35, the collecting component 33 is used to collect the fluid on the photovoltaic component 10; the processing component 35 includes a water inlet end and a water outlet end, the water inlet end is connected to the collecting component 33, and the water outlet end is connected to the water storage tank 31, and the processing component 35 is used to purify the fluid.

[0053] Specifically, in certain embodiments, the collection component 33 can collect fluids on the photovoltaic module 10, including but not limited to rainwater, melted snow, and cleaning liquids used to clean or cool the photovoltaic module 10. The processing component 35 has a water inlet connected to the collection component 33 and a water outlet connected to the water storage tank 31. Thus, the processing component 35 can transfer the purified clean liquid to the water storage tank 31 for storage, to be used by the first spray assembly 20 for spraying. The arrangement of the collection component 33 and the processing component 35 facilitates water recycling, thereby reducing water consumption and lowering the operating cost of the first spray assembly 20.

[0054] In some embodiments, a first flow channel and a second flow channel are provided in the nozzle 23. The first flow channel is used to communicate with the spray pipe 21 so that the first spray assembly 20 is in the first mode. The second flow channel is used to communicate with the spray pipe 21 so that the first spray assembly 20 is in the second mode.

[0055] Specifically, in some embodiments, when the cleaning liquid in the spray pipe 21 flows into the first flow channel, the nozzle 23 can spray the cleaning liquid onto the photovoltaic module 10 in the form of a high-pressure water flow. In this case, the first spray assembly 20 is in the first mode. When the cleaning liquid in the spray pipe 21 flows into the second flow channel, the nozzle 23 can spray the cleaning liquid onto the photovoltaic module 10 in the form of atomized water vapor. In this case, the first spray assembly 20 is in the second mode. It should be noted that in some embodiments, the nozzle 23 can selectively open the first flow channel or the second flow channel to switch the first spray assembly 20 between the first mode and the second mode.

[0056] In other embodiments, the nozzle 23 includes a first nozzle 23 and a second nozzle 23, the first nozzle 23 is connected to the spray pipe 21 and is used to put the first spray assembly 20 in the first mode, and the second nozzle 23 is connected to the spray pipe 21 and is used to put the first spray assembly 20 in the second mode.

[0057] Specifically, in some embodiments, when the cleaning liquid in the spray pipe 21 flows into the first nozzle 23, the nozzle 23 can spray the cleaning liquid onto the photovoltaic assembly 10 in the form of a high-pressure water flow. In this case, the first spray assembly 20 is in the first mode. When the cleaning liquid in the spray pipe 21 flows into the second nozzle 23, the nozzle 23 can spray the cleaning liquid onto the photovoltaic assembly 10 in the form of atomized water vapor. In this case, the first spray assembly 20 is in the second mode. It should be noted that in some embodiments, the spray pipe 21 can selectively communicate with the first nozzle 23 and the second nozzle 23 to enable the first spray assembly 20 to switch between the first mode and the second mode.

[0058] Please continue reading Figure 1 In some embodiments, the angle between the nozzle 23 and the photovoltaic module 10 is greater than 0° and less than 90°. That is, the angle between the centerline of the nozzle outlet of the nozzle 23 and the photovoltaic module 10 is greater than 0° and less than 90°. It should be noted that, in some embodiments, the angle between the nozzle 23 and the photovoltaic module 10 can be any one of the values in the range of greater than 0° and less than 90°, such as 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, and 85°, or any value between any two values.

[0059] If the angle between the nozzle 23 and the photovoltaic module 10 is 0°, it will be difficult for the nozzle 23 to spray the cleaning liquid onto the photovoltaic module 10, affecting the normal operation of the first spray assembly 20. If the angle between the nozzle 23 and the photovoltaic module 10 is 90°, the high-pressure water flow will directly hit the photovoltaic module 10, easily causing damage to the photovoltaic module 10 and shortening the service life of the photovoltaic module 10. In certain embodiments of the present application, the angle between the nozzle 23 and the photovoltaic module 10 is greater than 0° and less than 90°, that is, the nozzle 23 can spray the photovoltaic module 10 at an angle. This can ensure that the first spray assembly 20 effectively performs the cleaning and cooling functions of the photovoltaic module 10. On the other hand, compared with a 90° angle between the nozzle 23 and the photovoltaic module 10, that is, compared with a vertical spraying of the nozzle 23, the photovoltaic module 10 is less likely to be damaged by the impact of the water flow, thereby extending the service life of the photovoltaic module 10. On the other hand, the inclined spraying can increase the coverage area of the water flow, improve the cleaning coverage rate, reduce the cleaning dead angle, and thus improve the cleaning and heat dissipation effects.

[0060] In some embodiments, the first spray assembly 20 further includes a driving unit, which is configured to drive the nozzle 23 to rotate so as to adjust the angle between the nozzle 23 and the photovoltaic assembly 10 .

[0061] Specifically, in some embodiments, the drive unit can drive the nozzle 23 to rotate so that the angle between the nozzle 23 and the photovoltaic module 10 switches within the angle range of (0°, 90°), thereby increasing the spray range of the nozzle 23 on the photovoltaic module 10, which is conducive to achieving full coverage cleaning or cooling, and thus can improve the cleaning and heat dissipation effects. Exemplarily, the drive unit can drive the nozzle 23 to rotate relative to the photovoltaic module 10 so that the angle between the nozzle 23 and the photovoltaic module 10 gradually decreases, so that the nozzle 23 sprays the photovoltaic module 10 from near to far.

[0062] In some embodiments, the first spray assembly 20 further includes a moving unit, which is connected to the first spray assembly 20 and is used to drive the first spray assembly 20 to move relative to the photovoltaic assembly 10 .

[0063] Specifically, in some embodiments, the mobile unit can drive the nozzle 23 of the first spray assembly 20 and the spray pipe 21 connected to the nozzle 23 to move relative to the photovoltaic assembly 10, thereby increasing the spray range of the nozzle 23 on the photovoltaic assembly 10, which is conducive to achieving full coverage cleaning or cooling, and thus can improve the cleaning and heat dissipation effects.

[0064] In addition, the mobile unit can also drive the first spray assembly 20 to move relative to the photovoltaic assembly 10, so that the first spray assembly 20 moves to the dirty area or high-temperature area of the photovoltaic assembly 10, thereby achieving targeted cleaning or cooling of the photovoltaic assembly 10, thereby improving the cleaning and heat dissipation effects on the one hand; on the other hand, it can reduce the amount of cleaning liquid used and reduce resource consumption.

[0065] In addition, when the mobile unit drives the first spray assembly 20 to move relative to the photovoltaic assembly 10, the first spray assembly 20 can also clean foreign matter (such as fallen leaves, branches or snow, etc.) on the photovoltaic assembly 10, thereby preventing foreign matter from affecting the photoelectric conversion efficiency of the photovoltaic assembly 10, and thereby improving the power generation efficiency of the photovoltaic assembly 10.

[0066] See also Figure 1 and Figure 2 In some embodiments, the photovoltaic awning 100 further includes a frame structure 40, a second spray assembly 50, and a temperature adjustment assembly 60. The frame structure 40 is used to load the photovoltaic assembly 10 and together with the photovoltaic assembly 10 form an internal space 401; the second spray assembly 50 is provided on the frame structure 40 and is used to output high-pressure fine mist to the internal space 401; the temperature adjustment assembly 60 is provided on the frame structure 40 and is used to adjust the temperature of the internal space 401. It should be noted that, in some embodiments, the temperature adjustment assembly 60 includes but is not limited to a fan and an air conditioner. The embodiment of the present application is described by taking the example that the temperature adjustment assembly 60 includes an air conditioner.

[0067] Among them, the frame structure 40 is a structure in the photovoltaic awning 100 that can provide installation and support for the photovoltaic components 10. The frame structure 40 can be made of metal and / or non-metallic materials, and metal materials include but are not limited to aluminum, iron, steel or aluminum alloys, and non-metallic materials include but are not limited to plastics. Exemplarily, the frame structure 40 can be made of metal materials. For example, the frame structure 40 can be made of aluminum alloy, which can improve the structural strength of the frame structure 40, enhance the ability of the photovoltaic awning to withstand the external environment (such as wind, rain, snow, etc.), and ensure the stability and reliability of the photovoltaic awning 100. It should be noted that, in some embodiments, the overall shape of the frame structure 40 may include but is not limited to square, cylindrical and diamond shapes. In this way, the frame structure 40 can adapt to the installation of photovoltaic components 10 of different sizes and shapes.

[0068] In certain embodiments of the present application, when the photovoltaic assembly 10 is installed on the frame structure 40, the photovoltaic assembly 10 and the frame structure 40 can jointly form an internal space 401, and the internal space 401 is used for user leisure and entertainment or for placing items. In some embodiments, the photovoltaic assembly 10 can be installed on the frame structure 40 in a detachable connection manner, so that the photovoltaic assembly 10 can be easily removed from the frame structure 40 when it needs to be repaired or replaced. Among them, the detachable connection method includes but is not limited to bolt connection and snap connection. In other embodiments, the photovoltaic assembly 10 can be installed on the frame structure 40 in a non-detachable connection manner, so that the bonding strength between the photovoltaic assembly 10 and the frame structure 40 can be improved, the ability of the photovoltaic awning 100 to resist external environmental factors can be improved, and the stability and reliability of the operation of the photovoltaic awning 100 can be ensured. Among them, the non-detachable connection method includes but is not limited to bonding or welding.

[0069] Specifically, in some embodiments, the second spray assembly 50 can spray high-pressure fine mist into the interior space 401 to form a water mist layer in the interior space 401, and the temperature adjustment assembly 60 can deliver cooling air or heating air into the interior space 401. The second spray assembly 50 and the temperature adjustment assembly 60 can operate synchronously or alternately to adjust the temperature and humidity of the interior space 401.

[0070] For example, the second spray assembly 50 sprays high-pressure fine mist into the interior space 401, and at the same time, the temperature adjustment assembly 60 delivers cold air into the interior space 401. Thus, the second spray assembly 50 and the temperature adjustment assembly 60 can cooperate to jointly cool down and moisturize the interior space 401, thereby preventing the environment in the interior space 401 from being too dry and improving user comfort. In addition, when the second spray assembly 50 sprays high-pressure fine mist into the interior space 401 and the temperature adjustment assembly 60 delivers cold air into the interior space 401, the photovoltaic awning 100 can achieve rapid cooling through the complementary physical properties of water mist evaporation (latent heat cooling) and air conditioning refrigeration (sensible heat cooling), and compared with cooling using only the temperature adjustment assembly 60, the photovoltaic awning 100 consumes less power.

[0071] In some embodiments, the second spray assembly 50 includes a nozzle, and the angle between the nozzle and the photovoltaic assembly 10 is in the range of [15°, 30°]. That is, the angle between the centerline of the nozzle of the nozzle and the photovoltaic assembly 10 is in the range of [15°, 30°]. This can prevent the water mist output by the second spray assembly 50 from directly drifting toward the air outlet of the air conditioner or the human activity area. On the one hand, this can prevent the water mist from interfering with the air conditioner's control of the temperature in the interior space 401, resulting in increased power consumption, thereby ensuring a cooling effect while also reducing power consumption; on the other hand, it can improve human comfort and reduce the possibility of user discomfort. It should be noted that in some embodiments, the angle between the nozzle and the photovoltaic assembly 10 can be any one of 15°, 17°, 20°, 23°, 25°, 27°, and 30°, or any value between any two of these values.

[0072] See also Figure 1 and Figure 3 In certain embodiments, the control method comprises:

[0073] 01: Acquire characteristic information of the photovoltaic module 10, the characteristic information including the temperature of the photovoltaic module 10 and the amount of dust deposited on the photovoltaic module 10; and

[0074] 03: Control the first spray assembly 20 to switch between the first mode and the second mode according to the characteristic information.

[0075] The control method of the photovoltaic awning described above can be applied to the photovoltaic awning 100. The photovoltaic awning 100 of the embodiment of the present application includes a photovoltaic module 10 and a first spray module 20. The first spray module 20 is configured to be switchable between a first mode and a second mode. In the first mode, the first spray module 20 is used to output a high-pressure water flow to clean the photovoltaic module 10; in the second mode, the first spray module 20 is used to output atomized water vapor to cool the photovoltaic module 10. It should be noted that the photovoltaic awning 100 of this embodiment is exactly the same as the photovoltaic awning 100 in the above embodiment, and a repeated description will not be given here.

[0076] Furthermore, please combine Figure 2 In some embodiments, the photovoltaic awning 100 further includes a control component 70, which is capable of executing the control methods in 01 and 03, that is, the control component 70 is used to obtain characteristic information of the photovoltaic component 10, the characteristic information including the temperature of the photovoltaic component 10 and the amount of dust deposition of the photovoltaic component 10; and control the first spray component 20 to switch between the first mode and the second mode according to the characteristic information.

[0077] The control component 70 is a component that is at least used to analyze and process data and can issue instructions to the actuator or control the actuator. It should be noted that in some embodiments, the control component 70 can be a central processing unit (CPU); it can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), off-the-shelf programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0078] Specifically, in certain embodiments, the control assembly 70 is capable of acquiring characteristic information of the photovoltaic assembly 10, including the temperature of the photovoltaic assembly 10 and the amount of dust deposited on the photovoltaic assembly 10, and controlling the first spray assembly 20 to switch between the first mode and the second mode based on the characteristic information, thereby cleaning and cooling the photovoltaic assembly 10. For example, when the characteristic information includes the temperature of the photovoltaic assembly 10 and the temperature of the photovoltaic assembly 10 is greater than a preset temperature threshold, the control assembly 70 is capable of controlling the first spray assembly 20 to be in the first mode; and when the characteristic information includes the amount of dust deposited on the photovoltaic assembly 10 and the amount of dust deposited on the photovoltaic assembly 10 is greater than a preset dust deposition threshold, the control assembly 70 is capable of controlling the first spray assembly 20 to be in the second mode.

[0079] The control method of the photovoltaic awning of the embodiment of the present application can obtain the characteristic information of the photovoltaic component 10, and control the first spray component to switch between the first mode and the second mode according to the characteristic information. On the one hand, it can avoid dust deposition causing the transmittance of the photovoltaic component 10 to decrease, thereby improving the photoelectric conversion efficiency of the photovoltaic component 10; on the other hand, it can avoid the performance degradation caused by overheating of the photovoltaic component 10, thereby improving the photoelectric conversion efficiency of the photovoltaic component 10; on the other hand, it can prevent the photovoltaic component 10 from being damaged by overheating, thereby extending the service life of the photovoltaic component 10 and improving the safety performance of the photovoltaic component 10.

[0080] See also Figure 1 and Figure 4 In some embodiments, 03: controlling the first spray assembly 20 to switch between the first mode and the second mode according to the characteristic information includes:

[0081] 031: Determine the area of the photovoltaic assembly 10 to be sprayed according to the characteristic information; and

[0082] 033: Control the first spray assembly 20 corresponding to the area to be sprayed to switch between the first mode and the second mode.

[0083] Please combine Figure 2 The control component 70 is also used to execute the control methods in 031 and 033, that is, the control component 70 is used to determine the area to be sprayed of the photovoltaic component 10 according to the characteristic information; and control the first spray component 20 corresponding to the area to be sprayed to switch between the first mode and the second mode.

[0084] Specifically, in some embodiments, the control component 70 can determine the area to be sprayed of the photovoltaic component 10 based on the characteristic information. The area to be sprayed can be a dirty area on the photovoltaic component 10 (an area where the dust deposition amount on the photovoltaic component 10 is greater than a preset dust deposition amount threshold) or a high-temperature area (an area on the photovoltaic component 10 where the temperature is greater than a preset temperature threshold), and control the first spray component 20 corresponding to the area to be sprayed to switch between the first mode and the second mode, thereby achieving targeted cleaning or cooling of the photovoltaic component 10, which can improve the cleaning and heat dissipation effects on the one hand; on the other hand, it can reduce the amount of cleaning liquid used and reduce resource consumption.

[0085] Further, see Figure 1 and Figure 5 In some embodiments, before controlling the first spray assembly 20 corresponding to the area to be sprayed to switch between the first mode and the second mode, the method further includes:

[0086] 032: Control the moving unit to drive the first spraying assembly 20 to move relative to the photovoltaic assembly 10 so as to be opposite to the area to be sprayed.

[0087] Please combine Figure 2 The control component 70 is also used to execute the control method in 032, that is, the control component 70 is used to control the moving unit to drive the first spraying component 20 to move relative to the photovoltaic component 10 so as to be opposite to the area to be sprayed.

[0088] Specifically, in some embodiments, the control component 70 can control the mobile unit to drive the first spray component 20 to move relative to the photovoltaic component 10, so that the first spray component 20 moves to a position relative to the area to be sprayed, that is, the control component 70 can control the mobile unit to drive the first spray component 20 to move relative to the photovoltaic component 10 to a position relative to the dirty area or high-temperature area, thereby achieving targeted cleaning or cooling of the photovoltaic component 10, and thus on the one hand can improve the cleaning and heat dissipation effects; on the other hand, it can reduce the amount of cleaning liquid used and reduce resource consumption.

[0089] See also Figure 1 and Figure 6 In some embodiments, the control method further comprises:

[0090] 05: Obtain the water storage amount in the water tank 31;

[0091] 06: When the water storage amount is less than the preset water amount, the first spray assembly 20 is controlled to be in the first mode;

[0092] 07: When the water storage amount is greater than the preset water amount, the first spray assembly 20 is controlled to switch between the first mode and the second mode according to the characteristic information.

[0093] Please combine Figure 2 The control component 70 is also used to execute the control methods in 05, 06 and 07, that is, the control component 70 is used to obtain the water storage amount in the water tank 31; when the water storage amount is less than the preset water amount, the first spray component 20 is controlled to be in the first mode; when the water storage amount is greater than the preset water amount, the first spray component 20 is controlled to switch between the first mode and the second mode according to the characteristic information.

[0094] Specifically, in some embodiments, the control component 70 is capable of obtaining the water storage amount in the water tank 31, and when the water storage amount is less than a preset water amount, controlling the first spray component 20 to be in the first mode, that is, when the water storage amount is small, the cleaning operation is given priority; when the water storage amount is greater than the preset water amount, controlling the first spray component 20 to switch between the first mode and the second mode according to the characteristic information, that is, when the water storage amount is sufficient, the working mode of the first spray component 20 is adaptively adjusted according to the characteristic information.

[0095] Among them, the preset water volume can be a known value, which can be a value obtained before the control component 70 leaves the factory, a value manually input after the control component 70 leaves the factory, or a value obtained by the control component 70 processing historical data after the control component 70 leaves the factory.

[0096] See also Figure 1 and Figure 7 In some embodiments, the control method further comprises:

[0097] 08: Obtaining environmental information of the internal space 401, including temperature and humidity; and

[0098] 09: Control the operation of the second spray component 50 and / or the temperature adjustment component 60 according to the environmental information to cool the internal space 401.

[0099] Please combine Figure 2 The control component 70 is also used to execute the control methods in 08 and 09, that is, the control component 70 is used to obtain environmental information of the internal space 401, the environmental information including temperature and humidity; and control the operation of the second spray component 50 and / or the temperature adjustment component 60 according to the environmental information to cool the internal space 401.

[0100] Specifically, in some embodiments, the control component 70 can obtain environmental information of the interior space 401 and control the operation of the second spray component 50 and / or the temperature adjustment component 60 based on the environmental information to cool the interior space 401. For example, the control component 70 can control the operation of the second spray component 50 based on the environmental information to cool the interior space 401; or, the control component 70 can control the operation of the temperature adjustment component 60 based on the environmental information to cool the interior space 401; or, the control component 70 can control the second spray component 50 and the temperature adjustment component 60 to operate synchronously based on the environmental information to jointly cool the interior space 401.

[0101] When the second spray assembly 50 and the temperature adjustment assembly 60 operate synchronously, the photovoltaic awning 100 can achieve rapid cooling through the complementary physical properties of water mist evaporation (latent heat cooling) and air conditioning refrigeration (sensible heat cooling). Compared with cooling using only the temperature adjustment assembly 60, the photovoltaic awning 100 consumes less power. In addition, the second spray assembly 50 sprays high-pressure fine mist into the interior space 401, which can prevent the environment in the interior space 401 from being too dry, thereby improving the user experience.

[0102] Furthermore, in some embodiments, 09: controlling the second spray assembly 50 and / or the temperature adjustment assembly 60 to operate according to the environmental information to cool the internal space 401 includes:

[0103] When the temperature of the internal space 401 is greater than a preset temperature threshold and the humidity of the internal space 401 is less than a preset humidity threshold, the second spray assembly 50 is preferentially controlled to operate.

[0104] The control component 70 is also used to execute the above control method, that is, the control component 70 is used to preferentially control the operation of the second spray component 50 when the temperature of the internal space 401 is greater than the preset temperature threshold and the humidity of the internal space 401 is less than the preset humidity threshold.

[0105] Specifically, in some embodiments, the control component 70 can prioritize the operation of the second spray component 50 when the temperature of the internal space 401 is greater than a preset temperature threshold and the humidity of the internal space 401 is less than a preset humidity threshold. For example, if the preset temperature threshold is 30°C and the preset humidity threshold is 60%, then when the temperature of the internal space 401 is greater than 30°C and the humidity of the internal space 401 is less than 60%, the control component 70 can prioritize the operation of the second spray component 50.

[0106] In other embodiments, the control component 70 can control the second spray component 50 and the temperature adjustment component 60 to operate alternately to maintain the temperature of the internal space 401 within a preset temperature range, and to maintain the humidity of the internal space 401 within a preset humidity range. For example, the preset temperature range is 23°C-25°C, and the preset humidity range is 40%-60%. The control component 70 can control the second spray component 50 and the temperature adjustment component 60 to operate alternately to maintain the temperature of the internal space 401 within the range of 23°C-25°C, and to maintain the humidity of the internal space 401 within the range of 40%-60%. It should be noted that in some embodiments, the preset temperature threshold can be the maximum value of the preset temperature range, and the preset humidity range can be the maximum value of the preset humidity range.

[0107] See also Figure 1 and Figure 8 The present application also provides a storage medium 300 on which a computer program 310 is stored. When the computer program 310 is executed by one or more processors 330, the control method described in any of the previous embodiments is implemented.

[0108] For example, please combine Figure 1 When the computer program 310 is executed by the processor 330, the following control method is implemented:

[0109] 01: Acquire characteristic information of the photovoltaic module 10, the characteristic information including the temperature of the photovoltaic module 10 and the amount of dust deposited on the photovoltaic module 10; and

[0110] 03: Control the first spray assembly 20 to switch between the first mode and the second mode according to the characteristic information.

[0111] For another example, when the computer program 310 is executed by the processor 330, the control methods in 031, 032, 033, 05, 06, 07, 08 and 09 can also be implemented.

[0113] In the storage medium 300 in the present application, the first spray assembly 20 cooperates with the photovoltaic assembly 10 and is configured to be able to switch between a first mode and a second mode. In the first mode, the first spray assembly 20 is used to output a high-pressure water flow to clean the photovoltaic assembly 10; in the second mode, the first spray assembly 20 is used to output atomized water vapor to cool the photovoltaic assembly 10. Therefore, the setting of the first spray assembly 20 can, on the one hand, avoid dust deposition and cause the transmittance of the photovoltaic assembly 10 to decrease, thereby improving the photoelectric conversion efficiency of the photovoltaic assembly 10; on the other hand, it can avoid the performance degradation caused by overheating of the photovoltaic assembly 10, thereby improving the photoelectric conversion efficiency of the photovoltaic assembly 10; on the other hand, it can prevent the photovoltaic assembly 10 from being damaged by overheating, thereby extending the service life of the photovoltaic assembly 10 and improving the safety performance of the photovoltaic assembly 10.
