When the light intensity reaches the first target value, the window opener is controlled to extend to adjust the photovoltaic panel assembly to unfold relative to the supporting base frame, and the rotation angle is adjusted according to the light angle so that the surface of the photovoltaic panel assembly is perpendicular to the light direction or at an acute angle.

[0010] According to some embodiments of this application, the sensor includes a wind sensor, and the environmental information detected by the wind sensor includes wind speed; The controller is configured to: When the wind speed reaches the second target value, the window opener is controlled to retract or remain in place to adjust the retraction of the photovoltaic panel assembly relative to the supporting base. When the wind speed is less than the second target value, the window opener is controlled to extend to adjust the photovoltaic panel assembly to unfold relative to the supporting base.

[0011] According to some embodiments of this application, the environmental information detected by the wind sensor also includes wind direction; The controller is configured to adjust the rotation angle according to the wind direction during the process of controlling the window opener to extend when the wind speed is less than the second target value, so that the surface of the photovoltaic panel assembly forms an acute or obtuse angle with the wind direction.

[0013] According to some embodiments of this application, the supporting frame includes an upper crossbeam and a lower crossbeam, the upper crossbeam and the lower crossbeam are arranged horizontally vertically, the upper crossbeam and the lower crossbeam are provided with adhesive parts to adhere the balcony glass, and two window openers are provided, the two window openers are connected between the two ends of the upper crossbeam and the lower crossbeam.

[0014] According to some embodiments of this application, the glass protection structure includes balcony glass and mounting railings disposed on both sides of the balcony glass, and the supporting base is connected to the mounting railings.

[0015] According to some embodiments of this application, the support frame includes an upper crossbeam and a lower crossbeam, the upper crossbeam and the lower crossbeam are arranged horizontally vertically, and mounting seats are provided at the left and right ends of the upper crossbeam and the lower crossbeam; The mounting base is supported on the mounting railing, snapped onto the mounting railing, or fixedly connected to the mounting railing.

Simultaneously, environmental information is acquired in real time during the unfolding process, and the system is retracted promptly when the light intensity is insufficient or the wind speed increases. Furthermore, during the unfolding process, the rotation angle of the photovoltaic panel modules is adjusted in real time based on the angle of sunlight and wind direction, ensuring that the photovoltaic panel modules maintain high working efficiency and avoid the burden of vertical wind exposure.

[0026] Balcony photovoltaics is a small-scale solar power generation system installed on a residential balcony or in a small outdoor space. It converts solar energy into electrical energy through photovoltaic modules, directly powering daily household needs and providing a convenient distributed energy solution.

[0027] Balcony photovoltaic (PV) systems typically consist of core components such as PV modules, micro-inverters, mounting systems, and anti-backflow meters; some systems also include energy storage devices. Balcony PV systems are suitable for meeting partial household electricity needs, such as powering devices like mobile phones, computers, and refrigerators. Compared to traditional rooftop PV systems, balcony PV systems are characterized by their small size, flexible installation, and plug-and-play functionality, requiring no major modifications to the building structure.

[0028] In existing technologies, balcony photovoltaic systems require manual angle adjustment, lack intelligence, and cannot meet user needs.

[0029] Therefore, this application provides an intelligent control system for a balcony photovoltaic system, which can solve the problem of insufficient intelligence in traditional structures.

[0030] Reference Figures 1 to 11 In some embodiments of this application, the intelligent control system for a balcony photovoltaic system includes a support frame 100, a photovoltaic panel assembly 200, a window opener 300, sensors, and a controller. The support frame 100 is fixedly connected to the glass protective structure of the balcony to achieve the installation and fixation of the photovoltaic system on the balcony. The upper end of the photovoltaic panel assembly 200 is rotatably connected to the support frame 100. During rotation, the photovoltaic panel assembly 200 can rotate and unfold relative to the support frame 100, or retract relative to the support frame 100. The window opener 300 is disposed on the support frame 100 and connected to the photovoltaic panel assembly 200 to drive the photovoltaic panel assembly 200 to rotate. The sensors are used to detect environmental information of the photovoltaic panel assembly 200. The environmental information can be set as needed, and the type and number of sensors can be flexibly set according to the environmental information collected. The controller connects the window opener 300 and the sensors. The controller is configured to acquire environmental information and control the operation of the window opener 300 based on the environmental information to adjust the rotation angle of the photovoltaic panel assembly 200 relative to the support frame 100.

[0031] It is understood that the intelligent control system of the balcony photovoltaic system in this embodiment sets up sensors to detect the environmental information of the photovoltaic panel module 200, and then analyzes the environmental information through the controller so that the photovoltaic panel module 200 will only rotate and unfold under suitable conditions, and maintain the folded posture with the support base 100 when the environment is not suitable, thereby realizing the intelligent rotation adjustment of the photovoltaic panel module 200, which can effectively solve the problem of insufficient intelligence in traditional structures.

[0032] In some embodiments of this application, the sensor includes a light sensor, and the environmental information detected by the light sensor includes the light angle and light intensity. In this embodiment, the controller is configured to perform the following controls: When the light intensity is less than the first target value, the window opener 300 is controlled to retract or remain in place to adjust the photovoltaic panel assembly 200 relative to the support base 100. When the light intensity reaches the first target value, the window opener 300 is extended to adjust the photovoltaic panel assembly 200 to unfold relative to the support base 100, and the rotation angle is adjusted according to the light angle so that the surface of the photovoltaic panel assembly 200 is perpendicular to the light direction or at an acute angle.

[0033] Since the photovoltaic panel module 200 needs to be exposed to a certain intensity of sunlight in order to effectively convert solar energy, it cannot perform solar energy conversion operations when the weather conditions are bad and the sunlight intensity is weak, or at night. This embodiment controls the rotation of the photovoltaic panel module 200 by detecting and analyzing the sunlight intensity, which can ensure that the photovoltaic panel module 200 can operate effectively and achieve intelligent control.

[0034] Meanwhile, adjusting the rotation angle of the photovoltaic panel module 200 according to the angle of sunlight, so that its panel surface faces the sunlight, can effectively improve the working efficiency of the photovoltaic panel module 200.

[0035] In this embodiment, the first target value is the minimum light intensity set by the operator for the photovoltaic panel module 200 to effectively convert solar energy. The specific value is not limited here and is a parameter that can be flexibly adjusted by those skilled in the art as needed.

[0036] Understandably, when significant weather changes cause daytime sunlight intensity to drop below the first target value, the controller will control the photovoltaic panel module 200 to rotate and retract, effectively coping with severe weather and preventing damage to the photovoltaic panel module 200. Therefore, the structural design of this embodiment enables intelligent control based on sunlight.

[0037] To achieve the above judgment, the controller integrates at least a light angle calculation unit and a light intensity calculation unit to judge the light angle and light intensity.

[0038] In some embodiments of this application, the sensor includes a wind sensor, and the environmental information detected by the wind sensor includes wind speed. The controller in this embodiment is configured to perform the following controls: When the wind speed reaches the second target value, control the window opener 300 to retract or remain in place, so as to adjust the photovoltaic panel module 200 relative to the support base 100. When the wind speed is less than the second target value, the window opener 300 is extended to adjust the photovoltaic panel assembly 200 to unfold relative to the support base 100.

[0039] Understandably, in high wind conditions, the photovoltaic panel module 200 would be subjected to significant impact. Therefore, deploying it under such conditions could subject the balcony's glass protective structure to considerable external force, posing a safety hazard. Furthermore, the photovoltaic panel module 200 is also susceptible to damage from other objects blown down by strong winds. This embodiment uses wind speed for control and judgment, effectively avoiding the aforementioned risks and hazards, thereby improving the reliability and safety of automatic control.

[0040] In this embodiment, the second target value is the maximum wind speed value set by the operator that may affect the stable operation of the photovoltaic panel module 200. If the wind speed is less than the second target value, it is determined that the current wind speed will not have a significant impact on the photovoltaic panel module 200 and is within the safe range. However, if the wind speed reaches the second target value, it is determined that the current wind speed will have a significant impact on the photovoltaic panel module 200, and the angle of retraction of the photovoltaic panel module 200 is controlled or it is completely retracted.

[0041] Furthermore, in some embodiments of this application, the environmental information detected by the wind sensor also includes wind direction. The controller in this embodiment is configured to adjust the rotation angle according to the wind direction during the process of extending the window opener 300 when the wind speed is less than a second target value, so that the surface of the photovoltaic panel assembly 200 forms an acute or obtuse angle with the wind direction.

[0042] Since the photovoltaic panel 200 experiences the greatest force when the wind direction is perpendicular to its surface, this embodiment adjusts the orientation of the photovoltaic panel 200 by combining the wind direction with the orientation of the panel. This avoids the photovoltaic panel 200 continuously experiencing the maximum force under the current wind direction, which helps ensure the stable operation of the photovoltaic system.

[0043] To achieve the above judgment, the controller integrates at least a wind speed calculation unit and a wind direction calculation unit to perform wind speed and wind direction judgment.

[0044] In some embodiments of this application, the glass protection structure includes a balcony glass 400, and a support base 100 is bonded to the balcony glass 400, thereby achieving installation and fixation on the balcony.

[0045] In this embodiment, the support frame 100 is installed and fixed by bonding the balcony glass 400. It can be installed at any position on the balcony. Especially with the widespread use of glass railings, it can effectively solve the installation problem of photovoltaic systems.

[0046] It should be noted that although the window opener 300 is telescopic, it possesses a certain degree of rigidity, thus effectively driving the photovoltaic panel module 200 to rotate and adjust. The type of window opener 300 can be flexibly selected according to needs, and will not be described in detail here.

[0047] Reference Figures 2 to 3 In some embodiments of this application, the support frame 100 includes an upper crossbeam 101 and a lower crossbeam 102, which are arranged horizontally. Two window openers 300 are provided, connected between the two ends of the upper crossbeam 101 and the lower crossbeam 102. Since the upper end of the photovoltaic panel assembly 200 is rotatably connected to the support frame 100, i.e., connected to the upper crossbeam 101, the two window openers 300 are arranged on the left and right sides of the upper crossbeam 101 to connect the photovoltaic panel assembly 200, which facilitates support and rotation adjustment from both sides of the photovoltaic panel assembly 200, ensuring its stability and smoothness.

[0048] At the same time, the upper and lower crossbeams 101 and 102 are used to fix the upper and lower ends of the window opener 300, which can effectively ensure the installation strength of the window opener 300 and prevent it from loosening during the process of driving the photovoltaic panel module 200 to rotate.

[0049] Reference Figure 6 In some embodiments of this application, the upper crossbeam 101 and the lower crossbeam 102 include aluminum alloy profiles 104, each having four end faces and a groove 1041 formed therein. Referring to the figures, the cross-section of the aluminum alloy profile 104 is a four-sided symmetrical structure, with the center of each side recessed to form a groove 1041. The window opener 300 is spliced ​​onto the groove 1041 for quick installation. Adhesive portions 103 are provided on the upper crossbeam 101 and the lower crossbeam 102 in the groove 1041 that fits the balcony glass 400, and the balcony glass 400 is bonded to the surface through the adhesive portions 103.

[0050] The structural design of this embodiment, using an aluminum alloy profile 104 with four-sided formed grooves 1041, facilitates the installation of the adhesive part 103 to maintain a close fit with the balcony glass 400. It also facilitates the installation of the window opener 300.

[0051] Specifically, in some embodiments, right-angle brackets are provided at both the upper and lower ends of the window opener 300. These brackets are attached to the end faces of the aluminum alloy profile 104 and inserted into the grooves 1041 on the upper and lower end faces of the upper and lower crossbeams 101 and 102, respectively, and secured with screws. The adhesive part 103 is provided with a snap-fit ​​seat that engages with the groove 1041 to fix it to the end faces of the upper and lower crossbeams 101 and 102 that are attached to the balcony glass 400. An adhesive layer is also provided to bond the balcony glass 400.

[0052] The structural design of this embodiment allows for easy cutting of the lengths of the upper beam 101 and lower beam 102 according to the actual width of the photovoltaic panel module 200 and the actual width of the balcony glass 400, and facilitates installation and fixation. It is flexible in application and highly applicable.

[0053] In some embodiments, the adhesive portion 103 is a weather-resistant adhesive applied to the side of the upper crossbeam 101 and lower crossbeam 102 that is attached to the balcony glass 400.

[0054] Furthermore, in some embodiments, the upper crossbeam 101 and the lower crossbeam 102 are not formed into grooves 1041 on one side of the balcony glass 400, but rather into wavy surfaces, in order to increase the contact area with the weather-resistant adhesive and thus improve the adhesion.

[0055] In some embodiments of this application, the glass protective structure includes balcony glass 400 and mounting railings 402 disposed on both sides of the balcony glass, with a support base 100 connected to the mounting railings 402. By connecting the support base 100 to the mounting railings 402, the installation stability of the photovoltaic system can be effectively ensured, solving installation problems.

[0056] Reference Figures 4 to 5 In some embodiments of this application, the support frame 100 includes an upper crossbeam 101 and a lower crossbeam 102, which are arranged horizontally with the upper crossbeam 101 on top and the lower crossbeam 102 on the bottom. Mounting seats 1011 are provided at both ends of the upper crossbeam 101 and the lower crossbeam 102, which support the mounting railings 402. Since the upper crossbeam 101 and the lower crossbeam 102 support the mounting railings 402 on both sides of the balcony glass 400, they do not affect the balcony glass, effectively ensuring the reliability of the installation.

[0057] Furthermore, specifically, the mounting base 1011 is threadedly connected to multiple supporting bolts 1012. These supporting bolts 1012 can extend outwards relative to the mounting base 1011 by rotation, thereby securing the mounting railing 402. Nylon washers are provided on the side of the supporting bolts 1012 facing the mounting railing 402 to prevent damage to the railing 402. It is understandable that this supporting method facilitates the installation and application of photovoltaic systems without requiring structural modifications to the balcony glass 400 or the mounting railing 402.

[0058] In addition, installation can also be carried out by means of snap-fit ​​or bolt connection.

[0059] In some embodiments of this application, a hinge is provided between the photovoltaic panel assembly 200 and the supporting base 100. Since the photovoltaic panel assembly 200 needs to both conform to the supporting base 100 for folding relative to the balcony glass 400 and unfold to face sunlight, its rotation angle needs to meet a range of at least 0° to 180°. This embodiment, by using a hinge to connect the photovoltaic panel assembly 200 and the supporting base 100, effectively meets its rotation angle requirements, while simplifying the structural design and reducing production and design costs.

[0060] In some embodiments of this application, the window opener 300 is rotatably connected to the support base 100 so that it rotates along with the photovoltaic panel assembly 200 while controlling its rotation. It is understood that if the window opener 300 is fixedly connected to the photovoltaic panel assembly 200 when the photovoltaic panel assembly 200 rotates relative to the support base 100, then the window opener 300 needs to be angularly adjusted relative to the support base 100 to follow the rotation of the photovoltaic panel assembly 200; otherwise, interference will occur. This embodiment, by rotatably connecting the window opener 300 to the support base 100, allows the window opener 300 to adjust its angle along with the rotation of the photovoltaic panel assembly 200, effectively ensuring smooth rotation of the photovoltaic panel assembly 200 and avoiding interference.

[0061] Specifically, in this embodiment, the window opener 300 can be connected to the lower end of the photovoltaic panel assembly 200, and the rotation of the photovoltaic panel assembly 200 can be controlled by the window opener 300. The window opener 300 and the support base 100 can be connected by a hinge or by a rotating shaft structure, which is not specifically limited here.

[0062] Combination Figures 2 to 5 In some embodiments of this application, the window opener 300 is fixedly mounted on the support base 100, and the window opener 300 is configured as a curved chain electric window opener. In the prior art, there is a type of window opener 300 whose chain has a certain curvature when extended; therefore, when using a curved chain electric window opener, the chain can automatically adapt to the rotation angle of the photovoltaic panel module 200. The curved chain electric window opener can adopt the structure of the prior art, and will not be described in detail here.

[0063] It is understandable that this embodiment simplifies the installation design by configuring the window opener 300 as a curved chain electric window opener, which can be directly fixedly installed on the support base 100. The position of the window opener 300 only needs to be designed according to the chain curvature of the curved chain electric window opener.

[0064] Reference Figure 9 In some embodiments of this application, the supporting base 100 is further provided with a reinforcing bracket, which is connected to the railing 401 above the balcony glass 400. It is understood that if the balcony is an open structure, the photovoltaic panel module 200 will be affected by the external environment, such as wind and rain, and may be at risk of falling off. This embodiment, by providing a reinforcing bracket to connect the railing 401 above the balcony glass 400, can effectively improve the installation strength of the photovoltaic system and mitigate or even avoid the risk of falling off.

[0065] Furthermore, since balconies are typically several meters wide, and there are multiple balcony glass panes 400 along the width of the balcony, multiple photovoltaic systems can be installed. In this embodiment, a reinforcing bracket is used to connect the railing handrail 401, which can be used to maintain a consistent distance between each photovoltaic system and the railing handrail 401, thereby maintaining a consistent installation height for multiple photovoltaic systems, preserving the overall integrity of the installation, facilitating installation management, and avoiding a chaotic layout.

[0066] Reference Figure 9 In some embodiments of this application, the reinforcing bracket includes a support rod 105 and a strap (not shown in the figure). The lower end of the support rod 105 is engaged with a groove 1041 in the upper crossbeam 101, and its position can be adjusted along the length of the groove 1041 according to installation needs to connect to the appropriate position of the railing handrail 401. A flexible pad 106 is provided at the upper end of the support rod to flexibly abut against the bottom of the railing handrail 401 and avoid scratches. At the same time, a buckle is provided in the upper area of ​​the support rod. One end of the strap is fixedly connected to the support rod 105, and the other end is detachably connected to the buckle after passing around the railing handrail 401. This achieves the connection with the railing handrail 401.

[0067] It is understood that in this embodiment, the support rod 105 can limit the spacing between the upper crossbeam 101 and the railing handrail 401, thereby maintaining a consistent distance from each photovoltaic system to the railing handrail 401, and thus maintaining a consistent height. Furthermore, since the railing handrail 401 comes in various shapes and cross-sectional dimensions, this embodiment uses binding straps to wrap the railing handrail 401, which is compatible with various styles and cross-sectional dimensions of railing handrail 401, thus having a wide range of applications.

[0068] Specifically, the buckle adopts a self-locking clamp buckle. With the clamp open relative to the support rod 105, the free end of the strap can be inserted between the clamp and the support rod 105, and then the clamp is fastened to tighten the strap for quick fixation. The specific structural form of the self-locking clamp buckle can be set with reference to existing technology, and will not be described in detail here.

[0069] Reference Figures 7 to 11In some embodiments of this application, the photovoltaic panel assembly 200 includes a clamping mechanism 201 and a photovoltaic panel body 202. Specifically, the clamping mechanism 201 is rotatably connected to the support base 100, and the clamping mechanism 201 is provided with a clamping space. The photovoltaic panel body 202 is disposed in the clamping space and clamped and fixed by the clamping mechanism 201. Since the photovoltaic panel body 202 has different thicknesses, and the photovoltaic panel body 202 will cause some shading when it is attached to the balcony glass 400, this embodiment uses the clamping mechanism 201 to clamp the photovoltaic panel body 202, which can be used to accommodate photovoltaic panel bodies 202 of different thicknesses, thereby improving the applicability. At the same time, the photovoltaic panel body 202 can also be disassembled separately when needed by the user to reduce shading.

[0070] Furthermore, in some application scenarios, the photovoltaic panel 202 can be removed, and the clamping mechanism 201 can be rotated relative to the supporting base 100 to form a drying rack for users to use for other purposes.

[0071] Reference Figure 7 and Figure 8 Specifically, in some embodiments of this application, the clamping mechanism 201 includes a mounting frame 2011 and a clamping part 2012. The mounting frame 2011 is rotatably connected to the support base 100 to support the entire photovoltaic panel assembly 200. The mounting frame 2011 is rotatably connected to a plurality of connecting rods 2013 in a vertical direction. The clamping part 2012 is rotatably connected to the plurality of connecting rods 2013, so that it moves closer to or further away from the mounting frame 2011 by the rotation of the plurality of connecting rods 2013. It is understood that, due to the action of the plurality of connecting rods 2013, the clamping part 2012 will translate closer to or further away from the mounting frame 2011, thereby jointly defining a clamping space with the mounting frame 2011. When installing the photovoltaic panel 202, first control the clamping part 2012 away from the mounting frame 2011, then place the photovoltaic panel 202 between the mounting frame 2011 and the clamping part 2012, and then control the clamping part 2012 to move closer to the mounting frame 2011 to clamp it.

[0072] Reference Figures 7 to 11Furthermore, in some embodiments, the lower end of the mounting bracket 2011 is provided with a receiving boss 2014 to support the photovoltaic panel 202 when it is placed in. Connecting rods 2013 are provided on the left and right sides of the mounting bracket 2011, and two clamping parts 2012 are provided, correspondingly installed on the left and right sides of the mounting bracket 2011. An adjusting seat 2015 protrudes from the upper end of the mounting bracket 2011, and an adjusting groove 2019 is formed on the adjusting seat 2015. A threaded connection part 2016 is provided at the upper end of the clamping part 2012, and the threaded connection part 2016 has a threaded hole. The clamping mechanism 201 also includes an adjusting bolt 2017, which passes through the adjusting groove 2019 from top to bottom and connects to the threaded hole. A hand-tightening nut 2018 is hinged to the upper end of the adjusting bolt 2017.

[0073] In practical applications, users can control the rotation of the adjusting bolt 2017 by hand-tightening the nut 2018, thereby adjusting the up-and-down movement of the clamping part 2012. Based on the linkage of the connecting rod 2013, the clamping part 2012 will move closer to or further away from the mounting frame 2011 during the up-and-down movement, thereby clamping or releasing the photovoltaic panel 202. Users can remove the photovoltaic panel 202 from the top or put it in from the top. The operation is simple and easy to promote.

[0074] Furthermore, in order to avoid damage to the photovoltaic panel 202, a flexible structure can be provided on the opposing sides of the mounting bracket 2011 and the clamping part 2012.

[0075] Furthermore, in some embodiments, the hand-tightening nut 2018 has an extended state and a retracted state during rotation. In the retracted state, the hand-tightening nut 2018 is completely attached to the adjusting seat 2015, making it difficult to control the rotation of the adjusting bolt 2017. In the extended state, the hand-tightening nut 2018 extends upward relative to the adjusting seat 2015, facilitating the rotation of the adjusting bolt 2017. Moreover, when the hand-tightening nut 2018 rotates from the retracted state to the extended state, it pulls the adjusting bolt 2017 downward a certain distance, causing the clamping part 2012 to move away from the mounting frame 2011. Conversely, when the hand-tightening nut 2018 rotates from the extended state to the retracted state, it pulls the adjusting bolt 2017 upward a certain distance, causing the clamping part 2012 to move closer to the mounting frame 2011. Thus, by simply controlling the rotation of the hand-tightening nut 2018, the photovoltaic panel 202 can be quickly clamped and released. The adjustment of the adjusting bolt 2017 can be applied to compatibility with different thicknesses, or to situations where further adjustment of the distance between the clamping part 2012 and the mounting bracket 2011 is required.

[0076] Based on the structural foundation provided by the above embodiments, embodiments of this application also propose an intelligent control method for a balcony photovoltaic system, applied to the aforementioned intelligent control system for the balcony photovoltaic system, comprising: Environmental information detection: Detects light intensity and wind speed. When the light intensity reaches the first target value and the wind speed is less than the second target value, controls the window opener 300 to extend and push the photovoltaic panel module 200 to rotate and unfold relative to the support base 100. Adjustment cruise: Detects the angle of illumination and wind direction, and adjusts the rotation angle according to the angle of illumination and wind direction so that the surface of the photovoltaic panel 200 is perpendicular to the direction of illumination or forms an acute angle, and at the same time forms an acute angle or an obtuse angle with the wind direction; and when any of the following conditions are met, the window opener 300 is controlled to retract, so as to adjust the photovoltaic panel 200 relative to the support base 100.

[0077] It is understandable that the intelligent control method for the balcony photovoltaic system in this embodiment first analyzes environmental information. Only when the light intensity and wind speed meet the working conditions will the photovoltaic panel module 200 be controlled to rotate and unfold to absorb solar energy. If the light intensity and wind speed do not meet the working conditions, it will remain in a retracted position to avoid ineffective operation or damage, such as at night or during typhoons. Simultaneously, during the unfolding process, environmental information is acquired in real time, and the panel is retracted promptly when the light intensity is insufficient or the wind speed increases. Furthermore, during the unfolding process, the rotation angle of the photovoltaic panel module 200 is adjusted in real time based on the light angle and wind direction, ensuring that the photovoltaic panel module 200 maintains high working efficiency and avoids the burden of vertical wind exposure. This embodiment achieves intelligent rotation adjustment of the photovoltaic panel module 200, effectively solving the problem of insufficient intelligence in traditional structures.

[0078] Furthermore, the control method of this embodiment also includes controlling the rotation angle of the photovoltaic panel module 200 relative to the support base 100 to be between 0° and 90° when the wind speed is less than the second target value but greater than the third target value. It can be understood that the third target value is a set value where the wind speed is less than the second target value.

[0079] Since the operation of the window opener 300 to drive the photovoltaic panel module 200 to unfold and retract takes time, when the wind speed increases to exceed the third target value but does not reach the second target value, it is determined that the trigger condition for directly retracting the photovoltaic panel module 200 has not been met. At this time, the wind force is already relatively strong. If the wind speed continues to increase to the second target value, it will take a certain amount of time to retract the photovoltaic panel module 200. If the rotation angle of the photovoltaic panel module 200 relative to the support base 100 is obtuse at this time, it will not be conducive to timely retraction for protection. This embodiment can effectively shorten the time for the photovoltaic panel module 200 to fully retract by timely limiting the rotation angle of the photovoltaic panel module 200 and keeping it at an acute angle or a right angle, so as to provide rapid protection and avoid damage due to excessive wind force.

[0080] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
