[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.
[0025] Figure 1 This is a method for improving the power generation efficiency of a photovoltaic module provided in this embodiment. The photovoltaic module is provided with an angle adjustment device, and the angle adjustment device is used to change the installation direction of the photovoltaic module in space.
[0026] The method may include the following steps:
[0027] Step 101, obtain the geographical information of the location where the photovoltaic module is located.
[0028] In some embodiments of the present application, the geographical information of the location where the photovoltaic module is located includes longitude, latitude, altitude, time zone, local time, etc. These information can be used to calculate the relative position between the photovoltaic module and the sun, so as to determine the optimal installation angle of the photovoltaic module. There are various ways to obtain geographical information, such as through satellite positioning, network query, manual input, etc.
[0029] For example, as Figure 2 shown, assuming that the photovoltaic module is installed on the roof of a building in Los Angeles, then the geographical information of the photovoltaic module can be obtained through satellite positioning as follows: longitude: -118.243683, latitude: 34.052235, altitude: 71 meters, time zone: Beijing time, local time: 8:00 am; these geographical information can be used in subsequent steps to determine the relative position between the photovoltaic module and the sun, so as to improve the power generation efficiency of the photovoltaic module.
[0030] Step 102, determine the relative position between the photovoltaic module and the sun according to the geographical information.
[0031] In some embodiments of the present application, determining the relative position of the photovoltaic module with respect to the sun based on the geographical information generally includes the solar altitude angle and the azimuth angle. The solar altitude angle refers to the angle between the sun's rays and the ground plane, and the azimuth angle refers to the angle between the projection of the sun's rays on the ground plane and the due south direction. Based on the geographical information, the solar altitude angle and the azimuth angle can be calculated using astronomical algorithms, thereby determining the relative position of the photovoltaic module with respect to the sun. The purpose of determining the relative position is to make the normal direction of the photovoltaic module consistent with the direction of the sun's rays, so as to achieve the maximum solar radiation intensity.
[0032] Exemplarily, assume that the photovoltaic module is installed on the roof of a building in Beijing. Then, based on the geographical information of the photovoltaic module, as follows: longitude: -118.243683, latitude: 34.052235, altitude: 71 meters, time zone: Beijing time, and the current date and time, for example: date: November 26, 2023, time: 08:44:24, using astronomical algorithms, the solar altitude angle and the azimuth angle can be calculated, for example: solar altitude angle: 35.6°, azimuth angle (angle with due south): -64.3°. These angles can be used to determine the relative position of the photovoltaic module with respect to the sun, thereby increasing the power generation of the photovoltaic module.
[0033] Step 103, determining a first setting angle of the photovoltaic module according to the relative position; the first setting angle is the setting angle of the photovoltaic module in space when it generates peak power.
[0034] In some embodiments of the present application, determining the first setting angle of the photovoltaic module according to the relative position, that is, the angle that makes the normal direction of the photovoltaic module consistent with the direction of the sun's rays. The first setting angle includes the tilt angle and the azimuth angle. The tilt angle refers to the angle between the plane of the photovoltaic module and the horizontal plane, and the azimuth angle refers to the angle between the normal direction of the plane of the photovoltaic module and the due south direction. According to the relative position, the first setting angle can be calculated using geometric relationships, so that the photovoltaic module generates peak power.
[0035] Exemplarily, as Figure 2 shown, assume that the calculated solar altitude angle and azimuth angle of the photovoltaic module are as in the above example: solar altitude angle: -35.6°, azimuth angle: -64.3°; then using geometric relationships, the first setting angle of the photovoltaic module can be calculated, for example: tilt angle: 54.4°, azimuth angle: -64.3°; these angles can be used to set the direction of the photovoltaic module, thereby increasing the power generation of the photovoltaic module.
[0036] Step 104, setting the photovoltaic module according to the first setting angle through the angle adjustment device to increase the power generation of the photovoltaic module.
[0037] In some embodiments of the present application, the photovoltaic module is set according to the first set angle to improve the power generation efficiency of the photovoltaic module. The angle control device can be a mechanical, electrical or electronic device that can automatically adjust the tilt angle and azimuth angle of the photovoltaic module according to the input angle information to make them consistent with the first set angle. Through the angle control device, the adaptive adjustment of the photovoltaic module can be realized, reducing manual intervention and errors, and improving the stability and reliability of the photovoltaic module.
[0038] Exemplarily, assuming that the calculated tilt angle and azimuth angle of the photovoltaic module are as in the above example: tilt angle: 54.4°, azimuth angle: -64.3°, the direction of the photovoltaic module can be set according to this data to improve the power generation efficiency of the photovoltaic module. The angle control device can be an electric turntable that can automatically rotate the plane of the photovoltaic module according to the input tilt angle and azimuth angle to make it consistent with the direction of the sunlight. Through the electric turntable, the adaptive adjustment of the photovoltaic module can be realized, reducing manual intervention and errors, and improving the stability and reliability of the photovoltaic module.
[0039] Step 105: Obtain the information of the obstacles at the location where the photovoltaic module is located, and correct the set angle of the photovoltaic module according to the first set angle and the obstacle information to improve the power generation efficiency of the photovoltaic module.
[0040] In another embodiment of the present application, the information of the obstacles at the location where the photovoltaic module is located is obtained, and the set angle of the photovoltaic module is corrected according to the first set angle and the obstacle information to improve the power generation efficiency of the photovoltaic module. The obstacle information may refer to the position, shape, size, color, etc. of the objects in the surrounding environment of the location where the photovoltaic module is located that may cause shadows or reflections on the photovoltaic module. This information can be used to judge the influence degree of the obstacles on the photovoltaic module, so as to determine whether it is necessary to correct the set angle of the photovoltaic module. There are various ways to obtain the obstacle information, such as taking pictures through a camera, scanning with a radar, manual input, etc.
[0041] For example, assume that a photovoltaic module is installed on the roof of a building in Beijing. Then, information about the obstacles at the location of the photovoltaic module can be obtained by taking pictures with a camera. For example: Obstacle 1: A tall tree, located in the northwest direction of the photovoltaic module, about 50 meters away from the photovoltaic module, with a height of about 20 meters, a conical shape, and a color of green; Obstacle 2: A high-rise building, located in the southeast direction of the photovoltaic module, about 100 meters away from the photovoltaic module, with a height of about 40 meters, a cuboid shape, and a color of gray. This obstacle information can be used to correct the installation angle of the photovoltaic module according to the first installation angle and the obstacle information, so as to improve the power generation efficiency of the photovoltaic module. For example, if Obstacle 1 will cast a shadow on the photovoltaic module during a certain period, then the inclination angle and azimuth angle of the photovoltaic module can be slightly adjusted through an angle control device to avoid the shadow, thereby improving the power generation efficiency of the photovoltaic module. If Obstacle 2 will cause reflection on the photovoltaic module during a certain period, then the inclination angle and azimuth angle of the photovoltaic module can be slightly adjusted through an angle control device to utilize the reflection, thereby improving the power generation efficiency of the photovoltaic module.
[0042] In summary, in the embodiment of the present application, by obtaining the geographical information of the location where the photovoltaic module is located, the relative position between the photovoltaic module and the sun can be determined, thereby providing a basis for the installation direction of the photovoltaic module, avoiding blind or fixed installation methods, increasing the probability and intensity of the photovoltaic module receiving sunlight, determining the first installation angle of the photovoltaic module according to the relative position, enabling the installation angle of the photovoltaic module in space to reach the optimal state for generating peak power, thus maximizing the utilization of solar energy and improving the power generation efficiency of the photovoltaic module. Then, through the angle control device, the photovoltaic module can be installed according to the first installation angle, realizing the automatic adjustment of the photovoltaic module, reducing manual intervention and errors, improving the stability and reliability of the photovoltaic module. At the same time, by obtaining the obstacle information of the location where the photovoltaic module is located and correcting the installation angle of the photovoltaic module according to the first installation angle and the obstacle information, the influence of obstacles on the photovoltaic module can be detected and avoided in time, thereby maximizing the power generation power of the photovoltaic module and solving the technical problems in the background art. Therefore, based on the method of the embodiment of the present application, the photovoltaic module can automatically adjust the angle of the photovoltaic module according to the environmental conditions in the installation environment, solving the problem that after the photovoltaic module is installed, it cannot receive the best sunlight under environmental occlusion to achieve the optimal output power.
[0043] Figure 2 Another method for improving the power generation efficiency of a photovoltaic module provided by an embodiment of the application, the photovoltaic module is provided with an angle control device for changing the installation direction of the photovoltaic module in space. Referring to Figure 2 , the method may include the following steps:
[0044] Step 201: Obtain the geographical information of the location where the photovoltaic module is located.
[0045] The method shown in this step has been described in step 101 and will not be elaborated here.
[0046] Step 202: Determine the relative position between the photovoltaic module and the sun according to the geographical information.
[0047] The method shown in this step has been described in step 102 and will not be elaborated here.
[0048] Optionally, the geographical information includes the local time and latitude of the installation location of the photovoltaic module, and the relative position between the photovoltaic module and the sun includes the altitude angle of the sun. Step 202 includes sub-step 2021 and sub-step 2022:
[0049] Sub-step 2021: Determine the declination angle and solar hour angle of the sun through the local time.
[0050] In some embodiments of the present application, the declination angle and solar hour angle of the sun are determined through the local time. The declination angle of the sun refers to the angle between the position of the sun on the celestial sphere and the celestial equator, and the solar hour angle refers to the angle between the position of the sun on the celestial sphere and the local meridian. According to the local time, the declination angle and solar hour angle of the sun can be calculated using astronomical formulas, providing a basis for determining the relative position between the photovoltaic module and the sun. There can be various formulas for calculating the declination angle and solar hour angle of the sun. For example, the formulas are as follows:
[0051] δ = 23.45sin(365 / 360(284 + n)); ω = 15(t - 12) + λ - 120;
[0052] Where δ is the declination angle of the sun, ω is the solar hour angle, n is the number of days of the local time, t is the number of hours of the local time, and λ is the local longitude. According to the local time, the declination angle and solar hour angle of the sun can be calculated using these formulas.
[0053] For example: Local time: November 26, 2023, 19:44:24; Number of days: n = 330; Number of hours: t = 19.74; Longitude: λ = -118.24; Using the formula, the declination angle and solar hour angle of the sun are calculated: Declination angle: δ = -20.88°, Solar hour angle: ω = -108.84°. These angles can be used to determine the relative position between the photovoltaic module and the sun, thereby improving the power generation efficiency of the photovoltaic module.
[0054] Sub-step 2022: Determine the altitude angle according to the declination angle, the solar hour angle, and the latitude. The altitude angle is calculated according to the following formula:
[0055] α = arcsin(sin(δ) × sin(φ) + cos(δ) × cos(φ) × cos(ω));
[0056] Where α is the altitude angle, δ is the declination angle, φ is the latitude, and ω is the solar hour angle.
[0057] In some embodiments of the present application, the altitude angle is determined according to the declination angle, the solar hour angle, and the latitude. The altitude angle refers to the angle between the sun's rays and the ground plane. According to the formula, the altitude angle can be calculated using trigonometric functions, thereby providing a basis for determining the relative position between the photovoltaic module and the sun. The altitude angle is calculated according to the following formula:
[0058] α = arcsin(sin(δ) × sin(φ) + cos(δ) × cos(φ) × cos(ω)).
[0059] For example: Declination angle: δ = -20.88°, Solar hour angle: ω = -108.84°, Latitude: φ = 34.05°. Using the formula, the altitude angle is calculated. For example: Altitude angle: α = -35.6°. This angle can be used to determine the relative position between the photovoltaic module and the sun, thereby improving the power generation efficiency of the photovoltaic module.
[0060] Optionally, the geographical information includes the local time and latitude of the installation location of the photovoltaic module. The relative position between the photovoltaic module and the sun includes the azimuth angle of the sun. Step 202 includes sub-step 2023 and sub-step 2024:
[0061] Sub-step 2023, determining the declination angle and solar hour angle of the sun through the local time.
[0062] The method shown in this step has been described in sub-step 2021 and will not be elaborated here.
[0063] Sub-step 2024, determining the azimuth angle according to the declination angle, the solar hour angle, and the latitude. The azimuth angle is calculated according to the following formula:
[0064] Az = arctan(sin(ω) × cos(ω) × sin(φ) - tan(δ) × cos(φ));
[0065] Where Az is the azimuth angle, δ is the declination angle, φ is the latitude, and ω is the solar hour angle.
[0066] In some embodiments of the present application, the azimuth angle is determined according to the declination angle, the solar hour angle, and the latitude. The azimuth angle refers to the included angle between the projection of the solar rays on the ground plane and the due south direction. According to the formula, the azimuth angle can be calculated using trigonometric functions, providing a basis for determining the relative position between the photovoltaic module and the sun. The azimuth angle is calculated according to the following formula:
[0067] Az = arctan(sin(ω)×cos(ω)×sin(φ) - tan(δ)×cos(φ));
[0068] Where Az is the azimuth angle, δ is the declination angle, φ is the latitude, and ω is the solar hour angle.
[0069] For example: declination angle: δ = -20.88°, solar hour angle: ω = -108.84°, latitude: φ = 34.05°. Using the formula, the azimuth angle is calculated. For example: azimuth angle: Az = -64.3°. This angle can be used to determine the relative position between the photovoltaic module and the sun, thereby improving the power generation efficiency of the photovoltaic module.
[0070] Step 203: Determine the first setting angle of the photovoltaic module according to the relative position; the first setting angle is the setting angle of the photovoltaic module in space when it generates peak power.
[0071] The method shown in this step has been described in step 103 and will not be elaborated here.
[0072] Optionally, the first setting angle includes the tilt angle of the photovoltaic module. The tilt angle is the included angle between the photovoltaic module and the ground. Based on sub-step 2021 and sub-step 2022, step 203 includes sub-step 2031:
[0073] Sub-step 2031: Determine the complementary angle of the altitude angle as the tilt angle of the photovoltaic module.
[0074] In some embodiments of the present application, the complementary angle of the altitude angle is determined as the tilt angle of the photovoltaic module. The tilt angle refers to the included angle between the photovoltaic module and the ground, which determines the included angle between the photovoltaic module and the solar rays, thereby affecting the power generation efficiency of the photovoltaic module. The principle of determining the tilt angle according to the complementary angle of the altitude angle is that when the normal direction of the photovoltaic module is consistent with the direction of the solar rays, the power generation efficiency of the photovoltaic module reaches the maximum. At this time, the included angle between the photovoltaic module and the ground is equal to the complementary angle of the included angle between the solar rays and the ground plane. The tilt angle is calculated through this process, providing a basis for setting the direction of the photovoltaic module.
[0075] For example: As Figure 3As shown in the figure, 1 is a photovoltaic module, 11 is the projection plane of the photovoltaic module 1 on the ground, x is the normal direction of the photovoltaic module, y is the projection direction of x in the plane 11, N is the due south direction, α is the altitude angle, β is the inclination angle, and the parallel double arrows are the sunlight. It can be easily seen that N and y are in the plane 11. At this time, if the altitude angle: α = 35.6°, then the inclination angle β = 90 - (35.6) = 54.4°. This angle can be used to set the direction of the photovoltaic module, thereby improving the power generation efficiency of the photovoltaic module.
[0076] Optionally, the first setting angle includes the direction of the photovoltaic module, and the direction is the included angle between the projection direction of the normal direction of the photovoltaic module on the ground and the due south direction. Based on sub-step 2023 and sub-step 2024, step 203 includes sub-step 2032:
[0077] Sub-step 2032, determine the azimuth angle as the direction of the photovoltaic module.
[0078] In some embodiments of the present application, the azimuth angle is determined as the direction of the photovoltaic module. The direction refers to the included angle between the projection direction of the normal direction of the photovoltaic module on the ground and the due south direction, which determines the horizontal included angle between the photovoltaic module and the sun rays, thereby affecting the power generation efficiency of the photovoltaic module. The principle of determining the direction according to the azimuth angle is that when the normal direction of the photovoltaic module is consistent with the direction of the sun rays, the power generation efficiency of the photovoltaic module reaches the maximum. At this time, the included angle between the projection direction of the normal direction of the photovoltaic module on the ground and the due south direction is equal to the included angle between the projection of the sun rays on the ground plane and the due south direction.
[0079] For example: as Figure 3 shown, the azimuth angle: Az = -64.3°, then the orientation of the photovoltaic module y = -64.3°. This angle can be used to set the direction of the photovoltaic module, thereby improving the power generation efficiency of the photovoltaic module.
[0080] Step 204, through the angle adjustment device, set the photovoltaic module according to the first setting angle to improve the power generation efficiency of the photovoltaic module.
[0081] The method shown in this step has been described in step 104 and will not be repeated here.
[0082] Step 205, obtain the information of the obstacles at the location where the photovoltaic module is located, and correct the setting angle of the photovoltaic module according to the first setting angle and the obstacle information to improve the power generation efficiency of the photovoltaic module.
[0083] The method shown in this step has been described in step 105 and will not be repeated here.
[0084] Optionally, step 205 includes sub-steps 2051 to 2053:
[0085] Sub-step 2051: Obtain the information of the obstacles at the location where the photovoltaic module is located.
[0086] In some embodiments of the present application, the information of the obstacles at the location where the photovoltaic module is located is obtained. The obstacle information may refer to the position, shape, size, color, etc. of the objects in the surrounding environment of the location where the photovoltaic module is located that may cast shadows or reflections on the photovoltaic module. These information can be used to determine the degree of influence of the obstacles on the photovoltaic module, so as to determine whether it is necessary to correct the setting angle of the photovoltaic module.
[0087] There are various ways to obtain the obstacle information. For example, it can be obtained by camera shooting, radar scanning, manual input, etc.
[0088] Optionally, sub-step 2051 includes sub-steps 20511 and 20512:
[0089] Sub-step 20511: Obtain the image around the photovoltaic module.
[0090] In some embodiments of the present application, the image around the photovoltaic module is obtained. The image may refer to the image or video of the scene around the photovoltaic module, which can be used to observe the lighting conditions and the surrounding environment of the photovoltaic module.
[0091] There are various ways to obtain the image. For example, it can be obtained by camera shooting, drone shooting, satellite shooting, etc.
[0092] Sub-step 20512: Determine the obstacle information around the photovoltaic module through the image; the obstacle information includes the shape, size, orientation of the obstacles around the photovoltaic module, and the distance between the obstacles and the photovoltaic module.
[0093] In some embodiments of the present application, the obstacle information includes the shape, size, orientation of the obstacles around the photovoltaic module, and the distance between the obstacles and the photovoltaic module. These information can be used to analyze the influence of the obstacles on the shadows or reflections of the photovoltaic module, so as to determine whether it is necessary to correct the setting angle of the photovoltaic module. There are various ways to determine the obstacle information. For example, it can be determined by image recognition algorithms, manual measurement, optical rangefinders, etc.
[0094] For example, through image recognition algorithms, the obstacles in the image, such as high-rise buildings, trees, billboards, etc., can be recognized, and their shapes, sizes, orientations, and distances from the photovoltaic module can be calculated to obtain the obstacle information. These information can be used to analyze the influence of the obstacles on the shadows or reflections of the photovoltaic module, so as to provide a basis for determining whether it is necessary to correct the setting angle of the photovoltaic module.
[0095] Sub-step 2052: Determine the second setting angle of the photovoltaic module according to the first setting angle and the obstacle information; the second setting angle is the setting angle in space when the photovoltaic module generates maximum power in the presence of obstacles around it.
[0096] In some embodiments of the present application, the second setting angle of the photovoltaic module is determined according to the first setting angle and the obstacle information. The second setting angle refers to the setting angle in space when the photovoltaic module generates maximum power in the presence of obstacles around it. According to the first setting angle and the obstacle information, photovoltaic system design software can be used for simulation analysis to calculate the power generation of the photovoltaic module at different setting angles, and the setting angle with the maximum power generation is selected as the second setting angle. The purpose of determining the second setting angle is to optimize the direction of the photovoltaic module considering the influence of obstacles, thereby improving the power generation efficiency of the photovoltaic module.
[0097] For example: The first setting angle: the inclination angle is 26°, and the direction is -64.3°; the obstacle information: there are high-rise buildings, trees, billboards, etc. around the photovoltaic module, which may cast shadows or reflections on the photovoltaic module; the second setting angle: using software to simulate and analyze the power generation of the photovoltaic module at different setting angles, it is found that when the inclination angle is 28° and the direction is -60°, the power generation of the photovoltaic module is the largest, which is 400W.

The light field image is a spatial image used to characterize the light direction of each point in the space around the photovoltaic module. It contains more light information and can be used to analyze the lighting conditions of the photovoltaic module and the influence of obstacles. There are various ways to draw the light field image, such as through a light field camera, light field rendering software, etc.
[0101] For example: First setting angle: the inclination angle is 26°, and the direction is -64.3°; Drawing method: By using a light field camera to capture the scene around the photovoltaic module, a light field image is obtained, and this image can be used to characterize the illumination direction of each point in the space around the photovoltaic module, thereby providing a basis for determining whether the setting angle of the photovoltaic module needs to be corrected.
[0102] Sub-step 20522, as Figure 4 shown in the upper right part of Figure 4 in which 2 is an obstacle, and based on the obstacle information, a physical image around the photovoltaic module is drawn; the physical image is a spatial image used to characterize the light-blocking objects at each point around the photovoltaic module.

Drawing method: By using a camera to capture, a physical image is obtained, and this image can be used to characterize the spatial image of the light-blocking objects at each point around the photovoltaic module, thereby providing a basis for determining whether the setting angle of the photovoltaic module needs to be corrected.
[0105] Sub-step 20523, as Figure 4 shown in the lower part of Figure 4 in which the shaded part is the shadow formed by the obstruction of the obstacle. The light field image and the physical image are superimposed to determine the shadow image around the photovoltaic module; the shadow image is a spatial image used to characterize the actual illumination situation at each point around the photovoltaic module.
[0106] In some embodiments of the present application, the light field image and the physical image are superimposed to determine the shadow image around the photovoltaic module. The shadow image refers to a spatial image used to characterize the actual illumination situation at each point around the photovoltaic module, which contains the illumination intensity and distribution of the photovoltaic module, as well as the influence of the obstacle on the shadow or reflection of the photovoltaic module. There are various ways to superimpose the light field image and the physical image, such as by using image processing software, ray tracing algorithms, etc.
[0107] For example, obtain a light field image and a physical graph, and superimpose the two to obtain a shadow image, which can be used to characterize the actual illumination conditions at various points around the photovoltaic module, thereby providing a basis for determining whether it is necessary to correct the setting angle of the photovoltaic module.
[0108] Sub-step 20524, as Figure 5 shown, determine the deflection angle when the photovoltaic module generates maximum power through the shadow image; the deflection angle is the deflection angle when the photovoltaic module generates the smallest shadow.
[0109] In some embodiments of the present application, determine the deflection angle when the photovoltaic module generates maximum power. The deflection angle refers to the deflection angle when the photovoltaic module generates the smallest shadow, which is the rotation angle of the photovoltaic module in the horizontal direction and is used to adjust the horizontal angle between the photovoltaic module and the sun's rays, thereby reducing the influence of the shadow or reflection of the obstacle on the photovoltaic module. Through the shadow image, the shadow area of the photovoltaic module at different deflection angles can be observed, and the deflection angle with the smallest shadow area is selected as the deflection angle. The purpose of determining the deflection angle is to optimize the direction of the photovoltaic module considering the influence of the obstacle, thereby improving the power generation efficiency of the photovoltaic module.
[0110] For example, as Figure 5 shown: Through image processing software, analyze the shadow area of the photovoltaic module at different deflection angles. It is found that when the deflection angle is -90° rotation, the shadow area of the photovoltaic module is the smallest, which is 0. Therefore, -90° is determined as the deflection angle, and this angle can be used to set the direction of the photovoltaic module, thereby improving the power generation power of the photovoltaic module.
[0111] Sub-step 20525, superimpose the deflection angle on the first setting angle to obtain the second setting angle.

The second setting angle refers to the setting angle in space when the photovoltaic module generates maximum power in the presence of obstacles around the photovoltaic module, and also includes the inclination angle and direction.
[0113] There are various ways to superimpose the deflection angle on the first setting angle. For example, through mathematical formulas, geometric figures, angle calculators, etc. These angles can be used to set the direction of the photovoltaic module, thereby improving the power generation power of the photovoltaic module.

[0115] Sub-step 205251, perform an angular displacement operation on the first set angle such that the change amount of the angular displacement is equal to the deflection angle to obtain the second set angle.
[0116] In some embodiments of the present application, the first set angle can also be transformed into the second set angle by means of angular displacement. The angular displacement operation refers to tilting the angle of the photovoltaic module without changing the orientation of the photovoltaic module. The change amount of the angular displacement operation is equal to the deflection angle, that is, the deflection angle when the photovoltaic module generates the minimum shadow. Through the angular displacement operation, the horizontal included angle between the photovoltaic module and the sun's rays can reach the optimal state, thereby reducing the influence of the shielding object on the shadow or reflection of the photovoltaic module and improving the power generation efficiency of the photovoltaic module.
[0117] For example: First set angle: inclination angle is 26°, direction is -64.3°; Deflection angle: (-10°, -10°); Angular displacement operation method: Through the angle control device, rotate the photovoltaic module counterclockwise by 10° along the horizontal direction, so that its direction changes from -64.3° to -54.3°; Second set angle: inclination angle is 26°, direction is -54.3°. In this way, the set angle of the photovoltaic module changes from the first set angle to the second set angle, thereby improving the power generation efficiency of the photovoltaic module.
[0118] Sub-step 2053, set the photovoltaic module according to the second set angle to improve the power generation efficiency of the photovoltaic module.
[0119] In some embodiments of the present application, the photovoltaic module is set according to the second set angle to improve the power generation efficiency of the photovoltaic module.

There are various ways to set the photovoltaic module according to the second set angle, such as through an angle control device, manual adjustment, intelligent control, etc.
[0120] For example: Second set angle: inclination angle is 28°, direction is -60°, setting method: Through the angle control device, according to the input inclination angle and direction, automatically adjust the plane of the photovoltaic module to make it consistent with the direction of the sun's rays, thereby improving the power generation efficiency of the photovoltaic module. This setting method can realize the adaptive adjustment of the photovoltaic module, reduce manual intervention and errors, and improve the stability and reliability of the photovoltaic module.
[0121] Step 206, obtain the DC power data generated by the photovoltaic module.
[0122] In some embodiments of the present application, obtaining the DC power data generated by the photovoltaic module, including voltage, current, power, etc., these data can be used to evaluate the power generation effect of the photovoltaic module and detect the working state of the photovoltaic module. There are various ways to obtain the DC power data, such as through an ammeter, a sensor, a data collector, etc.

For example, if there are abnormal fluctuations in the voltage or current, it may indicate that the photovoltaic module is blocked or damaged and needs to be adjusted or repaired in time. If the power is lower than expected, it may indicate that the installation angle of the photovoltaic module is inappropriate and needs to be recalculated or corrected.

By responding to the user's request operation and outputting and displaying the target performance information, it is convenient for the user to understand and evaluate the quality and performance of the photovoltaic module and select a suitable photovoltaic module.
[0138] For example, the preset conditions: the maximum power is not less than 400W, the efficiency is not less than 20%, the target performance includes: maximum power, efficiency, fill factor, and the request operation is that the user touches. At this time, if a request operation of "view performance" is sent to the control system of the photovoltaic module, the following can be output and displayed: the control system of the photovoltaic module displays the target performance information of the photovoltaic module to the user through the display screen.
[0139] Step 212, when the performance information does not meet the preset conditions, give an alarm prompt to the user.
[0140] In some embodiments of the present application, when the performance information does not meet the preset conditions, an alarm prompt is given to the user. The preset conditions may refer to the performance information of the photovoltaic module reaching or exceeding a certain standard or range. The alarm prompt may refer to sending a warning signal to the user in the form of sound, light, text, etc., to prompt the user that there is a problem with the performance information of the photovoltaic module and that it needs to be checked or processed. The purpose of giving an alarm prompt to the user is to remind the user to promptly discover and solve the faults or abnormalities of the photovoltaic module, as well as to prevent damage or potential safety hazards of the photovoltaic module.

Alarm prompt: The control system of the photovoltaic module uses a speaker to send a voice prompt of "The performance of the photovoltaic module is low, please check" to the user, and uses a red flashing light to send a warning signal to the user. These alarm prompts can remind the user to promptly discover and solve the faults or abnormalities of the photovoltaic module, as well as to prevent damage or potential safety hazards of the photovoltaic module.
