[0023] Example 1 This disclosure provides a method for adjusting the angle of a balcony photovoltaic module, which enables automatic and precise adjustment of the tilt angle of the balcony photovoltaic system and avoidance of shading.

[0024] Please see Figure 1 The method for adjusting the angle of the photovoltaic module on the balcony includes steps S101 to S103, and each step is described in detail below.

[0025] Step S101: Obtain the real-time spatiotemporal parameters and real-time surrounding shading parameters of the balcony photovoltaic system.

[0026] In this embodiment, real-time spatiotemporal parameters, including latitude and longitude information and time information, are obtained through the positioning module on the balcony photovoltaic system. At the same time, real-time surrounding shading parameters caused by buildings, trees, balcony railings, etc., are obtained through the infrared shading sensor on the balcony photovoltaic system. This enables a comprehensive perception of the photovoltaic module's operating environment, giving the balcony photovoltaic system environmental self-adaptation capabilities and improving the efficiency of angle adjustment.

[0027] Step S102: Determine the tilt angle of the unobstructed target based on the real-time spatiotemporal parameters and the real-time surrounding occlusion parameters.

[0028] In this embodiment, the control module in the balcony photovoltaic system combines real-time spatiotemporal parameters and real-time surrounding shading parameters to comprehensively determine the unshaded target tilt angle. This avoids the problem of theoretically optimal but actually shaded conditions caused by simply relying on the sun's position. It ensures that the determined target tilt angle is the actual optimal solution that can achieve maximum light reception and unshaded conditions under the current environment, effectively improving the photovoltaic power generation efficiency. It is especially suitable for balcony photovoltaic application scenarios in complex urban building environments.

[0029] Step S103: The unobstructed target tilt angle is taken as the angle of the photovoltaic module of the balcony photovoltaic system.

[0030] In this embodiment, the unobstructed target tilt angle is used as the photovoltaic module angle of the balcony photovoltaic system by the drive module, which ensures the scientific and practical nature of the angle adjustment, reduces the time cost of blind adjustment, and enhances the response speed and control accuracy.

[0031] It should be noted that, please refer to Figure 2 In this embodiment, the balcony photovoltaic system includes a photovoltaic module 201, a tracking bracket 202, a tilt sensor 203, a push rod 204, a drive module 205, a control box 206 (containing a control module, a positioning module, a network module, and a power module), a balcony mounting bracket 207, and a hinge 209 connecting the mounting bracket and the tracking bracket. The balcony mounting bracket 207 and the hinge 209 together form the balcony photovoltaic system, used to fix the balcony photovoltaic system on the balcony 208.

[0032] The tilt sensor is mounted on the tracking bracket 202. The power module supplies power to the entire system. The positive and negative terminals of the photovoltaic module 201 are connected through a T-connector. One end is connected to the charging module of the power module to supply power to the lithium battery; the other end is connected to the inverter of the balcony photovoltaic.

[0033] The push rod 204 has a built-in drive module 205. The control module outputs control signals to the drive module 205 to drive the push rod 204 to extend or retract to adjust the angle of the bracket.

[0034] The network module can access network data to obtain weather information, such as wind speed exceeding the protection value or snowfall. If this occurs, the lever will retract and enter protection mode.

[0035] Users can view the status information of the balcony photovoltaic system on the terminal module, and can also manually adjust the angle of the components as needed.

[0036] Please see Figure 3 In one specific embodiment, step S102 includes steps S1021 to S1022, and each step is described in detail below.

[0037] Step S1021: Based on a preset astronomical algorithm, the solar altitude angle is calculated according to the real-time spatiotemporal parameters.

[0038] In this embodiment, the solar altitude angle is calculated based on real-time spatiotemporal parameters using a preset astronomical algorithm. The preset astronomical algorithm can be a solar trajectory algorithm.

[0039] Step S1022: Determine the tilt angle of the unobstructed target based on the solar altitude angle and the real-time surrounding occlusion parameters.

[0040] In this embodiment, based on the initial alignment of the solar altitude angle, the final unobstructed target tilt angle is determined by combining real-time surrounding shading parameters. This retains the high irradiance tracking capability and avoids power generation losses caused by fixed structure shading, greatly improving the applicability and robustness of the system in real urban living environments.

[0041] In one specific embodiment, step S1022 includes: adjusting the angle of the photovoltaic module of the balcony photovoltaic to the solar altitude angle, and then adjusting the solar altitude angle according to the real-time surrounding shading parameters to obtain the unshaded target tilt angle.

[0042] In this embodiment, after adjusting the angle of the photovoltaic module of the balcony photovoltaic system to the solar altitude angle, the solar altitude angle is adjusted according to the current real-time surrounding shading parameters to obtain the unshaded target tilt angle, thereby obtaining a more accurate unshaded target tilt angle in practical applications.

[0043] Please see Figure 4In one specific embodiment, adjusting the solar altitude angle based on the real-time surrounding occlusion parameters to obtain the unobstructed target tilt angle includes steps S401-404, each of which will be described in detail below.

[0044] Step S401: Determine whether the real-time surrounding occlusion parameter is less than a preset occlusion threshold.

[0045] In this embodiment, the control module determines whether the real-time surrounding shading parameters are less than a preset shading threshold. The preset shading threshold can be determined based on the actual photovoltaic module application, and is not limited to this in this embodiment.

[0046] Step S402: If the real-time surrounding occlusion parameter is less than the preset occlusion threshold, then the solar altitude angle is used as the tilt angle of the unobstructed target.

[0047] In this embodiment, if the real-time surrounding shading parameters are less than the preset shading threshold, it can be known that when the photovoltaic module angle is the solar altitude angle, there are almost no obstructions or the obstructions have almost no impact on the photovoltaic module. Therefore, the control module directly uses the solar altitude angle as the unobstructed target tilt angle.

[0048] Step S403: If the real-time surrounding shading parameter is greater than or equal to the preset shading threshold, then the solar altitude angle is used as the candidate photovoltaic module tilt angle, and the candidate photovoltaic module tilt angle is adjusted based on the preset angle to obtain a new candidate photovoltaic module tilt angle.

[0049] In this embodiment, if the real-time surrounding shading parameters are greater than or equal to a preset shading threshold, it indicates that the shadow of the current shading object is affecting the photovoltaic module. The control module needs to use the solar altitude angle as a candidate photovoltaic module tilt angle and adjust the candidate photovoltaic module tilt angle based on a preset angle to obtain a new candidate photovoltaic module tilt angle. The preset angle can be determined according to the actual photovoltaic module application, and is not limited in this embodiment. Furthermore, adjusting the candidate photovoltaic module tilt angle based on the preset angle can be done by adding or subtracting the preset angle from the candidate photovoltaic module tilt angle.

[0050] Step S404: After adjusting the angle of the photovoltaic module of the balcony photovoltaic system to the new candidate photovoltaic module tilt angle, if the real-time surrounding shading parameter is less than the preset shading threshold, the new candidate photovoltaic module tilt angle is taken as the unshaded target tilt angle; if the real-time surrounding shading parameter is greater than or equal to the preset shading threshold, the step of adjusting the tilt angle of the candidate photovoltaic module based on the preset angle is repeated to obtain the new candidate photovoltaic module tilt angle.

[0051] In this embodiment, the angle of the photovoltaic module of the balcony photovoltaic system is adjusted to the new candidate photovoltaic module tilt angle by the driving module. If the real-time surrounding shading parameters obtained after adjustment are less than the preset shading threshold, it can be known that when the photovoltaic module angle is the candidate photovoltaic module tilt angle, there are almost no obstructions or the obstructions have almost no impact on the photovoltaic module. Therefore, the new candidate photovoltaic module tilt angle is taken as the target tilt angle without shading.

[0052] If the real-time surrounding shading parameters obtained after adjustment are greater than or equal to the preset shading threshold, then step S403 is re-executed to adjust the tilt angle of the candidate photovoltaic module based on the preset angle to obtain a new tilt angle of the candidate photovoltaic module, until the real-time surrounding shading parameters obtained after adjustment are less than the preset shading threshold.

[0053] Please see Figure 5 In one specific embodiment, the method further includes steps S501-502, which are described in detail below.

[0054] Step S501: Obtain real-time light intensity parameters and determine the photovoltaic module angle adjustment frequency based on the real-time light intensity parameters.

[0055] In this embodiment, the light intensity parameters of the current environment are obtained by a photosensitive sensor, and the angle adjustment frequency of the photovoltaic module is determined based on the current light intensity parameters.

[0056] During periods of relatively stable light intensity (such as at midday when light is stable), the rate of change in light intensity is low, thus automatically reducing the angle adjustment frequency. During periods of drastic light intensity fluctuations (such as in the early morning / evening or when cloud cover is frequent), the light intensity changes rapidly, thus increasing the adjustment frequency to track the effective light source.

[0057] Step S502: Adjust the angle of the photovoltaic module according to the photovoltaic module angle adjustment frequency.

[0058] In this embodiment, the angle of the photovoltaic module is adjusted according to the photovoltaic module angle adjustment frequency, which avoids high-frequency ineffective adjustment, extends the motor life, reduces power consumption, and improves the system energy efficiency ratio.

[0059] Please see Figure 6 In one specific embodiment, the method further includes steps S601-603, which are described in detail below.

[0060] Step S601: Obtain the real-time dust parameters of the photovoltaic modules of the balcony photovoltaic system.

[0061] In this embodiment, real-time dust parameters of the photovoltaic modules on the balcony are obtained to determine whether the dust on the photovoltaic modules on the balcony needs to be cleaned in order to avoid affecting the operation of the photovoltaic modules.

[0062] Step S602: If the real-time dust parameter of the photovoltaic module is greater than or equal to the preset dust accumulation threshold, then the angle of the photovoltaic module of the balcony photovoltaic is adjusted to the preset cleaning angle.

[0063] In this embodiment, if the real-time dust parameter of the photovoltaic module is greater than or equal to a preset dust accumulation threshold, it indicates that the photovoltaic module needs cleaning. Therefore, the angle of the photovoltaic module on the balcony is adjusted to a preset cleaning angle via the drive module. If the real-time dust parameter of the photovoltaic module is less than the preset dust accumulation threshold, it indicates that the photovoltaic module does not need cleaning, and the current angle of the photovoltaic module on the balcony is maintained.

[0064] Step S603: Until the real-time dust parameter of the photovoltaic module is less than the preset dust accumulation threshold, adjust the angle of the photovoltaic module to the unobstructed target tilt angle.

[0065] In this embodiment, the photovoltaic module automatically adjusts the angle of the photovoltaic module to the unobstructed target tilt angle until the real-time dust parameter of the photovoltaic module is less than the preset dust accumulation threshold, thereby realizing unattended operation throughout the process and improving user experience and system autonomy.

[0066] In one specific embodiment, the photovoltaic module includes multiple sub-modules, and the method further includes: determining the unshaded target tilt angle corresponding to each sub-module based on the real-time spatiotemporal parameters and the real-time surrounding shading parameters; and using the unshaded target tilt angle corresponding to each sub-module as the photovoltaic module angle corresponding to each sub-module.

[0067] In this embodiment, when a photovoltaic module includes multiple sub-modules, the installation of multiple modules is prone to partial shading and partial unshading. If the tilt angle is uniformly adjusted according to a target unshading angle, the angle of the unshading module will be suboptimal. Therefore, independent data acquisition and adjustment of each module is realized, and the total power generation efficiency is improved by 15%-20% in the multi-module scenario.

[0068] The balcony photovoltaic module angle adjustment method proposed in this embodiment obtains real-time spatiotemporal parameters and real-time surrounding shading parameters of the balcony photovoltaic system; determines the unshaded target tilt angle based on the real-time spatiotemporal parameters and the real-time surrounding shading parameters; and uses the unshaded target tilt angle as the photovoltaic module angle of the balcony photovoltaic system. In this way, by combining the real-time spatiotemporal parameters and the real-time surrounding shading parameters of the balcony photovoltaic system, and comprehensively analyzing the spatial relationship between the sun's position and environmental obstacles, the unshaded target tilt angle that can avoid shading and effectively receive solar radiation is dynamically determined, and the photovoltaic module angle is adjusted accordingly, significantly improving the light utilization efficiency and ensuring that the photovoltaic module always operates in the optimal posture for truly generating electricity.
