[0002] As the core component of the photovoltaic power generation system, the main function of the photovoltaic module is to efficiently convert solar energy into electrical energy. However, after installation, the transmittance of traditional photovoltaic modules is usually fixed, which brings some limitations in practical applications. Especially in some special scenarios, such as agricultural photovoltaic complementarity and building integrated photovoltaics (BIPV), not only efficient power generation is required, but also certain light transmittance requirements need to be met. For example, in agricultural photovoltaic complementarity projects, the transmittance of photovoltaic modules directly affects the growth of crops; in BIPV applications, the transmittance affects the lighting and aesthetics of buildings. Due to the fixed transmittance of traditional photovoltaic modules, it is difficult to achieve flexible adjustment in these scenarios, resulting in a contradiction between power generation efficiency and light transmittance requirements.

[0028] In a second aspect, the present application provides a photovoltaic system with adjustable transmittance, which is installed using the method provided in any embodiment of the present application.

[0029] The embodiments of the present application provide a photovoltaic system with adjustable transmittance and an installation method thereof, which aims to solve the problem of fixed transmittance of traditional photovoltaic modules after installation, especially in special scenarios such as agricultural-photovoltaic complementarity and building-integrated photovoltaics (BIPV), thereby improving flexibility and adaptability.

[0030] First, a first photovoltaic module and a second photovoltaic module are selected whose transmittance is greater than a preset transmittance. The preset transmittance is to ensure that the photovoltaic system can meet certain light transmission requirements in different application scenarios. At the same time, the provided mounting bracket includes a first mounting area and a second mounting area that are relatively arranged. The two mounting areas are used to fix the photovoltaic modules and can support the adjustment of the height and distance of the photovoltaic modules.

[0031] Then the backs of the first photovoltaic assembly and the second photovoltaic assembly are adjustably mounted on the first mounting area and the second mounting area of ​​the mounting bracket. Adjustable mounting means that the position of the photovoltaic assembly can be adjusted to meet different light transmission requirements and power generation efficiency requirements.

[0032] Then, the first cell arrangement information of the first photovoltaic module and the second cell arrangement information of the second photovoltaic module are obtained. The cell arrangement information includes the position, size and arrangement of the cells, which are very critical for subsequent adjustments.

[0033] Further, according to the first cell arrangement information and the second cell arrangement information, the target height and target distance corresponding to the first photovoltaic assembly and the second photovoltaic assembly are generated. The target height and target distance are determined to ensure that the cells between the photovoltaic assemblies do not block each other, thereby improving the light transmittance and power generation efficiency of the system.

[0034] Finally, according to the generated target height and target distance, the height of the first photovoltaic module and the second photovoltaic module are adjusted on the mounting bracket. During the adjustment process, it is necessary to ensure that the cells do not block each other, so as to achieve the best light transmittance and power generation efficiency. After completing the above adjustments, the installed photovoltaic system is finally obtained, which can flexibly adjust the light transmittance to meet the needs of different scenarios.

[0035] The provided installation method has at least the following beneficial effects:

[0036] 1. Improve light transmittance and power generation efficiency: By adjusting the height and distance of photovoltaic modules, ensure that the cells do not block each other, thereby improving light transmittance while maintaining high power generation efficiency. This is especially important for agricultural photovoltaic complementary projects because light transmittance directly affects the growth of crops.

[0037] 2. Enhanced flexibility: This method allows the transmittance of photovoltaic modules to be adjusted after installation, so that the system can be flexibly adjusted according to actual needs. For example, in different seasons or different time periods, the transmittance of photovoltaic modules can be dynamically adjusted according to the light intensity and the growth requirements of crops.

[0038] 3. Wide application scope: This method is not only applicable to agricultural photovoltaic complementary projects, but can also be widely used in scenarios such as building integrated photovoltaics (BIPV). In BIPV, light transmittance not only affects the lighting of the building, but also affects the beauty and comfort of the building. By dynamically adjusting the light transmittance, these needs can be better met.

[0039] 4. Optimize space utilization: By reasonably adjusting the position of photovoltaic modules, the utilization of space is optimized and the shading problem existing in the traditional fixed installation method is avoided. This helps to achieve higher power generation efficiency and better light transmission effect in a limited space.

[0040] 5. Improve user experience: In actual applications, users can adjust the light transmittance of the photovoltaic system according to their needs, which improves the practicality of the system and user satisfaction. Especially in buildings, the light transmittance can be flexibly adjusted according to the needs of indoor activities to improve the comfort of living and working.

[0041] 6. Reduce maintenance costs: Since the position of photovoltaic modules can be flexibly adjusted, the system can adapt to environmental changes more easily during long-term use, reducing maintenance costs caused by shading and other problems.

[0042] In summary, the photovoltaic system with adjustable transmittance and its installation method not only solve the problem of fixed transmittance of traditional photovoltaic modules, but also improve the flexibility, transmittance and power generation efficiency of the system through dynamic adjustment, and is suitable for a variety of special application scenarios.

[0052] It should also be understood that the term “and / or” used in the specification and appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0053] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0054] As the core component of the photovoltaic power generation system, the main function of the photovoltaic module is to efficiently convert solar energy into electrical energy. However, after installation, the transmittance of traditional photovoltaic modules is usually fixed, which brings some limitations in practical applications. Especially in some special scenarios, such as agricultural photovoltaic complementarity and building integrated photovoltaics (BIPV), not only efficient power generation is required, but also certain light transmittance requirements need to be met. For example, in agricultural photovoltaic complementarity projects, the transmittance of photovoltaic modules directly affects the growth of crops; in BIPV applications, the transmittance affects the lighting and aesthetics of buildings. Due to the fixed transmittance of traditional photovoltaic modules, it is difficult to achieve flexible adjustment in these scenarios, resulting in a contradiction between power generation efficiency and light transmittance requirements.

[0055] Therefore, there is an urgent need for a photovoltaic system with adjustable transmittance to solve at least one of the above problems.

[0056] To solve the above problems, please refer to Figure 1 , Figure 1 It is a schematic flow chart of the steps of a method for installing a photovoltaic system with adjustable transmittance provided in one embodiment of the present application.

[0057] Specifically, Figure 1 As shown, the photovoltaic system installation method with adjustable transmittance provided includes steps S101 to S106. The details are as follows:

[0058] Step S101. Provide a first photovoltaic component and a second photovoltaic component, wherein the light transmittance of the first photovoltaic component and the second photovoltaic component is greater than a preset light transmittance.

[0059] Specifically, a photovoltaic module with a transmittance greater than a preset transmittance is selected. These photovoltaic modules are usually made of translucent materials or specially designed to ensure sufficient transmittance while generating electricity efficiently. The preset transmittance is predetermined according to the needs of specific application scenarios (such as agricultural-photovoltaic complementarity, BIPV). For example, for agricultural-photovoltaic complementarity projects, the preset transmittance may be 30% to ensure that crops receive sufficient light. The transmittances of the first photovoltaic module and the second photovoltaic module are 40% and 50%, respectively, both of which meet this requirement. By ensuring that the photovoltaic modules have basic light transmittance before installation, a basis is provided for subsequent adjustments. The basic requirements for transmittance in different application scenarios are met to avoid unnecessary waste of materials.

[0060] Step S102: Provide a mounting bracket, wherein the mounting bracket includes a first mounting area and a second mounting area that are arranged opposite to each other.

[0061] Specifically, the mounting bracket includes a first mounting area and a second mounting area that are relatively arranged, and these two areas can adjust the installation position and angle of the photovoltaic module. The design of the mounting bracket needs to consider structural strength, weather resistance, installation convenience and adjustment flexibility. For example, the mounting bracket is made of aluminum alloy material, which has high strength and corrosion resistance. The first mounting area and the second mounting area are adjusted by adjusting the screw and the slide. Provide a stable mounting platform to ensure that the photovoltaic module can be installed safely and reliably. By adjusting the screw and the slide, the position and angle of the photovoltaic module can be flexibly adjusted to meet different light transmission requirements.

[0062] Step S103: The back side of the first photovoltaic module is adjustably mounted in the first mounting area, and the back side of the second photovoltaic module is adjustably mounted in the second mounting area.

[0063] Specifically, the backs of the first photovoltaic module and the second photovoltaic module are installed in the first installation area and the second installation area through an adjustment device (such as a screw rod or a slide groove). The design of the adjustment device needs to ensure that the photovoltaic modules can be easily adjusted in height and distance.

[0064] For example, the PV modules are fixed to the mounting bracket using a slide and a screw. The slide can be adjusted horizontally, and the screw can be adjusted vertically. The adjustable mounting method enables flexible adjustment of the height and distance of the PV modules. It is convenient for on-site installation and maintenance, and reduces installation time and cost.

[0065] Step S104: Acquire the first cell arrangement information of the first photovoltaic assembly and the second cell arrangement information of the second photovoltaic assembly.

[0066] Specifically, the cell arrangement information of the photovoltaic module is obtained through sensors or image recognition technology, including the position, size and arrangement of the cells. This information will be used to generate the target height and target distance to ensure that the cells do not block each other. For example, a camera is used to shoot the front of the photovoltaic module, and the position and size of the cells are identified through image processing software. Or the cell arrangement information has been preset when the photovoltaic module leaves the factory, which can be obtained by reading a label or data file. By accurately obtaining the cell arrangement information, accurate data support is provided for subsequent height and distance adjustments. It helps to optimize the layout of photovoltaic modules and improve power generation efficiency and light transmittance.

[0067] Step S105: Generate target heights and target distances corresponding to the first photovoltaic assembly and the second photovoltaic assembly according to the first solar cell arrangement information and the second solar cell arrangement information.

[0068] Specifically, the algorithm is used to generate the optimal height and distance based on the cell arrangement information to ensure that the cells do not block each other and improve light transmittance. The algorithm needs to consider multiple factors, such as the incident angle of sunlight, the efficiency of the cells, and the transmittance requirements. For example, using computer simulation software, input the cell arrangement information and transmittance requirements, and calculate the optimal height and distance through the optimization algorithm. The algorithm can be adjusted dynamically to optimize the layout of photovoltaic modules according to different times and seasons. By generating the optimal installation parameters, it is ensured that the photovoltaic modules generate electricity efficiently while meeting the light transmittance requirements. Through algorithm optimization, the overall performance and reliability of the system are improved.

[0069] Step S106. Adjust the heights of the first photovoltaic module and the second photovoltaic module on the mounting bracket according to the target height and the target distance to obtain an installed photovoltaic system so that the cells of the first photovoltaic module and the second photovoltaic module do not block each other and the light transmittance of the photovoltaic system is improved.

[0070] Specifically, according to the target height and target distance generated in step S105, the position of the photovoltaic module is adjusted using the adjustment device. After the adjustment is completed, the light transmittance and power generation efficiency are tested to ensure that the system meets the expected performance. If an electric adjustment device is used, the position of the photovoltaic module is automatically adjusted according to the generated height and distance parameters. The light transmittance and power generation efficiency are tested by a spectrometer and a power meter to ensure that the system performance meets the standards.

[0071] By achieving precise installation of photovoltaic modules, it is ensured that the cells do not block each other, thus improving power generation efficiency. It also improves the light transmittance of the photovoltaic system to meet the special needs of agricultural photovoltaic complementarity and BIPV scenarios.

[0072] In summary, through the above steps, the installed photovoltaic system with adjustable transmittance can not only efficiently convert solar energy into electrical energy, but also flexibly meet the light transmittance requirements of different application scenarios, thereby achieving better comprehensive performance and economic benefits.

[0073] In some embodiments, the number of the first photovoltaic components and the number of the second photovoltaic components are both multiple, and the back sides of the multiple first photovoltaic components can be adjusted to be installed in the first installation area, and the back sides of the multiple second photovoltaic components can be adjusted to be installed in the second installation area; the generating the target height and target distance corresponding to the first photovoltaic components and the second photovoltaic components according to the first cell arrangement information and the second cell arrangement information includes: respectively generating the first component position information and the second component position information corresponding to each first photovoltaic component and the second photovoltaic component according to the first cell arrangement information and the initial position information of each first photovoltaic component and the second cell arrangement information and the initial position information of each second photovoltaic component; adjusting the position of the corresponding first photovoltaic component on the mounting bracket according to each first component position information, and adjusting the position of the corresponding second photovoltaic component on the mounting bracket according to each second component position information, so that the cells of each first photovoltaic component and each second photovoltaic component on the mounting bracket do not block each other.

[0074] In practical applications, the number of first photovoltaic modules and second photovoltaic modules may be more than one, but multiple. For example, in a large-scale agricultural photovoltaic complementary project, multiple rows of first photovoltaic modules and multiple rows of second photovoltaic modules may be installed. The back of each photovoltaic module is installed on the corresponding installation area of ​​the mounting bracket through an adjustment device (such as a screw or a slide). The first installation area is used to install multiple first photovoltaic modules, and the second installation area is used to install multiple second photovoltaic modules. The first component position information and the second component position information are generated according to the cell arrangement information and initial position information of each first photovoltaic module and the second photovoltaic module. The cell arrangement information of each first photovoltaic module and the second photovoltaic module is obtained through sensors or image recognition technology, including the position, size and arrangement of the cell. The initial position information of each photovoltaic module on the mounting bracket is obtained, including the initial height and distance. The target position information of each photovoltaic module is generated according to the cell arrangement information and initial position information of each photovoltaic module using an algorithm. The target position information includes a target height and a target distance to ensure that the cells of all photovoltaic modules do not block each other.

[0075] According to the generated first component position information and second component position information, use an adjustment device (such as an electric adjustment device) to adjust the position of each photovoltaic component on the mounting bracket. After the adjustment is completed, the light transmittance and power generation efficiency are tested to ensure that the cells of each photovoltaic component do not block each other and the overall performance of the system meets expectations.

[0076] Furthermore, the multiple first photovoltaic assemblies and the second photovoltaic assemblies proposed in this embodiment have at least the following beneficial effects:

[0077] 1. Improve system flexibility: Through the adjustable installation of multiple photovoltaic modules, the system can flexibly adjust the position of each module in a larger area to adapt to different light transmission requirements and lighting conditions. For example, in an agricultural photovoltaic complementary project, the light transmittance of photovoltaic modules in different areas can be adjusted according to the needs of different crops, thereby optimizing the growth conditions of crops.

[0078] 2. Optimize power generation efficiency: Generate the best position information for each photovoltaic module through an algorithm to ensure that the cells do not block each other, thereby maximizing the power generation efficiency of each module. In the case of multiple photovoltaic modules, the power generation efficiency of the overall system is significantly improved because the impact of mutual blocking on power generation efficiency is avoided.

[0079] 3. Meet diverse application needs: The adjustable installation of multiple photovoltaic modules is not only suitable for agricultural photovoltaic complementary projects, but also can be applied to other scenarios such as building integrated photovoltaics (BIPV). For example, in BIPV applications, the position of photovoltaic modules can be flexibly adjusted according to the different lighting needs and appearance designs of the building, which not only ensures the power generation efficiency, but also improves the aesthetics and lighting effect of the building.

[0080] 4. Improve system reliability: Through precise position adjustment, ensure that the cells of each photovoltaic module do not block each other, reducing system failures and performance degradation caused by blocking. The use of electric adjustment devices can achieve automatic adjustment, reduce human errors and maintenance costs, and improve system reliability and stability.

[0081] 5. Dynamically adapt to changes in light: In a dynamically changing light environment, the system can adjust the position of the photovoltaic modules in real time through algorithms to adapt to different angles of sunlight incidence and light intensity. For example, as the seasons change, the angle of sunlight incidence changes, and the system can automatically adjust the position of the photovoltaic modules to ensure efficient power generation performance and light transmittance throughout the year.

[0082] 6. Easy installation and maintenance: The adjustable installation design of multiple photovoltaic modules makes the installation process easier, and the installation and position adjustment can be quickly completed through the electric adjustment device. During maintenance, the position of a certain component can be adjusted separately without reinstalling the entire system, which greatly reduces maintenance costs and time.

[0083] The content is now explained with a specific embodiment: Assume that in an agricultural photovoltaic complementary project, 10 rows of first photovoltaic modules and 10 rows of second photovoltaic modules need to be installed. The transmittance requirement for each row of photovoltaic modules is 30%. During the installation process: the transmittance of each row of first photovoltaic modules and second photovoltaic modules is 40% and 50% respectively. The mounting bracket is made of aluminum alloy material, has multiple first mounting areas and second mounting areas, and supports horizontal and vertical adjustment. Use a camera to shoot the front of each row of photovoltaic modules, and use image processing software to identify the position, size and arrangement of the cells. Record the initial position of each row of photovoltaic modules on the mounting bracket, including height and distance. Use an optimization algorithm to generate the target position information of each row of photovoltaic modules based on the cell arrangement information and initial position information of each row of photovoltaic modules. Ensure that the cells of all modules do not block each other and meet the transmittance requirements at the same time. According to the generated target position information, use an electric adjustment device to adjust the position of each row of photovoltaic modules on the mounting bracket. After the adjustment is completed, use a spectrometer and a power meter to test the transmittance and power generation efficiency of each row of photovoltaic modules to ensure that the system performance meets the standards. Through this embodiment, the photovoltaic system can not only generate electricity efficiently, but also flexibly meet the light transmission requirements of different areas, providing strong guarantees for the growth of crops and the aesthetics of buildings.

[0084] Exemplarily, the cell area corresponding to the first photovoltaic assembly is negatively correlated with the number of the first photovoltaic assembly; the cell area corresponding to the second photovoltaic assembly is negatively correlated with the number of the second photovoltaic assembly.

[0085] The cell area is negatively correlated with the number of PV modules, which means that as the number of PV modules increases, the cell area in each PV module will decrease accordingly. For example, if 10 first PV modules are installed, the cell area of ​​each module will be smaller than when 5 first PV modules are installed. Similarly, when the number of second PV modules increases, the cell area of ​​each module will also decrease.

[0086] By reducing the area of ​​the cells in each photovoltaic module, the light-transmitting area can be increased, thereby improving the overall light transmittance of the system. Under the premise of ensuring the total power generation area, by optimizing the layout of the cells in each module, a balance between higher light transmittance and power generation efficiency can be achieved. This is very beneficial for the growth of crops in agricultural photovoltaic complementary projects and the lighting of buildings in BIPV applications.

[0087] Although the cell area of ​​each photovoltaic module is reduced, by optimizing the layout and number of cells, the power generation efficiency can be improved without significantly affecting the total power generation area. For example, the spacing between cells can be optimized through algorithms to avoid shading and ensure that each cell can efficiently receive sunlight. The combination of multiple photovoltaic modules can more easily adapt to the needs of different scenarios. By adjusting the cell area of ​​each module, different transmittances and power generation efficiencies can be achieved in different areas. For example, in agricultural-photovoltaic complementary projects, the growth environment of different crops can be optimized by adjusting the number of photovoltaic modules and cell area in different areas.

[0088] Assume that in an agricultural photovoltaic complementary project, 10 rows of first photovoltaic modules and 10 rows of second photovoltaic modules need to be installed. The transmittance requirement for each row of photovoltaic modules is 30%. During the design process: the cell area of ​​each row of first photovoltaic modules is 0.5 square meters, and 10 modules are installed. The cell area of ​​each row of second photovoltaic modules is 0.4 square meters, and 10 modules are installed. Use a camera to shoot the front of each row of photovoltaic modules, and use image processing software to identify the position, size and arrangement of the cells. Record the initial position of each row of photovoltaic modules on the mounting bracket, including height and distance. Use an optimization algorithm to generate the target position information of each row of photovoltaic modules based on the cell arrangement information and initial position information of each row of photovoltaic modules. Ensure that the cells of all modules do not block each other and meet the transmittance requirements.

[0089] According to the generated target position information, the electric adjustment device is used to adjust the position of each row of photovoltaic modules on the mounting bracket. After the adjustment is completed, the transmittance and power generation efficiency of each row of photovoltaic modules are tested using a spectrometer and a power meter to ensure that the system performance meets the standard. Through the design of this example, when installing 10 first photovoltaic modules and 10 second photovoltaic modules, the cell area of ​​each module is reduced, the overall transmittance is improved, and a high power generation efficiency is maintained by optimizing the layout.

[0090] Exemplarily, adjacent first photovoltaic components are connected in series and / or in parallel; adjacent second photovoltaic components are connected in series and / or in parallel.

[0091] Multiple PV modules are connected in series to form a larger power output loop. Series connection can increase the voltage output of the system and is suitable for applications that require higher voltage. At the same time, multiple PV modules can also be connected in parallel to form a larger current output loop. Parallel connection can increase the current output of the system and is suitable for applications that require higher current. In some cases, series and parallel connections can be used together to achieve the best power output effect.

[0092] Through different connection methods, the power output characteristics of the photovoltaic system can be flexibly adjusted to adapt to different application scenarios and needs. Series connection is suitable for long-distance transmission and systems requiring higher voltage, while parallel connection is suitable for short-distance transmission and systems requiring higher current.

[0093] The series or parallel connection mode of adjacent photovoltaic modules can be flexibly selected according to actual needs, which improves the adaptability and flexibility of the system. For example, in scenarios where higher voltage output is required, series connection can be selected; in scenarios where higher current output is required, parallel connection can be selected. The series and parallel connection modes can optimize the power output characteristics of the system and improve the stability and reliability of the system. The series-connected system can reduce voltage drop and improve transmission efficiency during long-distance transmission; in the parallel-connected system, when a local component fails, other components can still work normally, which improves the redundancy of the system.

[0094] By properly selecting the connection method, the power output of the system can be optimized, and the power generation efficiency and energy utilization rate can be improved. For example, in some areas with sufficient sunlight, parallel connection can be selected to increase the current output; in areas with weak sunlight, series connection can be selected to increase the voltage output.

[0095] Series and parallel connection methods make the system easier to maintain and troubleshoot. For example, when a component fails, it can be isolated through parallel connection without affecting the normal operation of other components, thereby improving maintenance efficiency.

[0096] For example, on the roof of a building, a parallel connection method is selected to increase the current output and meet the needs of short-distance power transmission. On the facade of a building, a series connection method is selected to increase the voltage output and meet the needs of long-distance power transmission. The method can select the appropriate connection method according to different application scenarios and needs to achieve flexible power output and higher system stability.

[0097] In some embodiments, the target height and target distance corresponding to the first photovoltaic assembly and the second photovoltaic assembly are generated according to the first cell arrangement information and the second cell arrangement information, including: parsing the first cell arrangement information to obtain the total height of the first cells, the first number of cells and the first cell spacing of the first photovoltaic assembly; parsing the second cell arrangement information to obtain the total height of the second cells, the second number of cells and the second cell spacing of the second photovoltaic assembly; obtaining the angle between the sunlight and the ground corresponding to the photovoltaic system; calculating the target height according to the total height of the first cells, the first cell spacing, the angle and the first cell number; calculating the target distance according to the total height of the second cells, the second cell spacing, the angle and the second cell number; adjusting the height of the first photovoltaic assembly according to the target height, and adjusting the height of the second cell according to the target height and the target distance.

[0098] The cell arrangement information of the first photovoltaic module is analyzed by sensors or image recognition technology, and the total height of the first cell is the total height of all the cells arranged vertically. The number of first cells is the number of cells in the first photovoltaic module. The first cell spacing is the spacing between the cells. Similarly, the total height of the second cell, the number of second cells and the second cell spacing are obtained. The angle between the sunlight and the ground obtained is the angle between the sunlight and the ground calculated or obtained according to the geographical location and time (such as season, date and time). This angle is an important parameter for determining the optimal installation height and distance of the photovoltaic module because it affects the incident angle of sunlight and the distribution of light.

[0099] Then, by accurately calculating the target height and target distance, it is ensured that the cells do not block each other, thereby maximizing the light receiving area and power generation efficiency of each photovoltaic module. Especially in environments with changing light conditions, such as different seasons and time periods, by dynamically adjusting the height and distance, efficient power generation performance can be continuously maintained. By optimizing the spacing and height of the cells, the light-transmitting area can be increased without affecting the power generation efficiency, thereby improving the light transmittance of the entire system. This is very beneficial for the growth of crops in agricultural photovoltaic complementary projects and the lighting of buildings in BIPV applications. The angle between sunlight and the ground is a dynamic parameter that changes with time and seasons. Calculating the target height and target distance based on this parameter can ensure that the system maintains optimal performance throughout the year. For example, in winter when the sun is low, the height and distance of the photovoltaic module can be adjusted to avoid blocking and ensure sufficient light. By parsing the cell arrangement information and obtaining detailed cell parameters, accurate data support can be provided for system design. It helps system designers to make more accurate layout plans and reduce design errors and subsequent adjustments.

[0100] Exemplarily, the expression of the target height includes:

[0101]

[0102] The expression of the target distance includes:

[0103]

[0104] in, is the target height, is the total height of the first battery cell, is the first battery cell spacing, is the number of the first battery cells, is the angle, is the target distance, is the total height of the second battery cell, is the second battery cell spacing, is the number of the second battery cells.

[0105] By calculating the target height and target distance through specific mathematical formulas, it is possible to ensure that each cell is in the best position to avoid obstruction, thereby maximizing the power generation efficiency of the system. This precise calculation method is applicable to various complex installation environments and lighting conditions. Since the angle between sunlight and the ground is a dynamic parameter, it will change with time and season. By calculating the target height and target distance through formulas, the position of the photovoltaic module can be adjusted in real time to adapt to different lighting conditions. For example, when the sun is high in summer, the angle is large, and the calculated target height and target distance will be reduced accordingly to ensure that the cell receives sunlight to the greatest extent. Through formula calculation, accurate data support can be provided for system design, helping designers to make more accurate layout planning, avoid design errors and subsequent adjustments. It helps to improve the design consistency and reliability of the system. At the same time, using formulas for calculations reduces the errors caused by human experience and judgment, and improves the installation accuracy and performance stability of the system.

[0106] It should be noted that, in some embodiments, adjusting the height of the second cell according to the target height and the target distance includes: obtaining the minimum anti-collision distance corresponding to the first photovoltaic component and the second photovoltaic component according to the total height of the first cell and the total height of the second cell; if the first cell is lower than the second cell, the expression of the height of the second cell includes:

[0107]

[0108] in, is the height of the second battery cell, is the target height, is the target distance.

[0109] By calculating the minimum anti-collision distance, it is possible to ensure that a certain safety distance is maintained between the first photovoltaic module and the second photovoltaic module, avoiding collision and damage caused by improper position adjustment. This improves the stability and reliability of the system and reduces potential safety hazards. By comprehensively considering the target height, target distance and minimum anti-collision distance, the layout of the second photovoltaic module can be optimized to ensure that the cells do not block each other while avoiding unnecessary waste of space. This helps to maximize the power generation area and light transmittance of the system. By accurately calculating the height of the second cell, it is possible to ensure that each photovoltaic module works in the best position, thereby improving the overall power generation efficiency and light transmittance of the system. The optimized layout reduces shading and collision and improves the energy utilization of the system.

[0110] In some embodiments, if the ambient light intensity corresponding to the photovoltaic system is higher, the target distance is greater; if the ambient light intensity corresponding to the photovoltaic system is lower, the target distance is smaller.

[0111] When the ambient light intensity of the photovoltaic system is high, the target distance needs to be set larger to ensure that the spacing between the cells is large enough to avoid shading, thereby maximizing the light receiving area and power generation efficiency. When the ambient light intensity of the photovoltaic system is low, the target distance can be set smaller to reduce the spacing between photovoltaic modules, thereby reducing the overall footprint and material costs while maintaining high light transmittance.

[0112] By increasing the target distance when the ambient light intensity is high, it is possible to ensure that the spacing between the cells is large enough to avoid shading, thereby maximizing the light receiving area and power generation efficiency. For example, when there is plenty of sunlight, a larger spacing can reduce the shadow effect so that each cell can fully receive sunlight.

[0113] By reducing the target distance when the ambient light intensity is low, the spacing between photovoltaic modules can be reduced under low light intensity conditions, while still maintaining high light transmittance and power generation efficiency. For example, when the sunlight is weak, a smaller spacing can concentrate the light and improve the power generation efficiency per unit area.

[0114] By collecting ambient light intensity data in real time or periodically, the system can dynamically adjust the target distance of photovoltaic modules to adapt to different lighting conditions. This flexibility allows the system to maintain optimal performance in different time periods and seasons. Whether it is an agricultural photovoltaic complementary project or a BIPV (building integrated photovoltaic) application, the system can optimize and adjust according to changes in ambient light intensity to improve the adaptability and flexibility of the overall application. When the ambient light intensity is low, by reducing the spacing between photovoltaic modules, installation space and material costs can be saved. For example, on cloudy days or in winter, when the intensity of sunlight is low, reducing the spacing can reduce the demand for light-transmitting materials and reduce system costs. When the ambient light intensity is high, by increasing the spacing, the light transmittance of photovoltaic modules can be further improved, the shadow effect can be reduced, and the power generation efficiency can be improved.

[0115] In some embodiments, Figure 2 As shown, after obtaining the installed photovoltaic system, steps S107 to S108 are also included.

[0116] Step S107: Acquire real-time heating information corresponding to the first photovoltaic assembly and the second photovoltaic assembly.

[0117] Step S108. Adjust the relative distance between the first photovoltaic component and the second photovoltaic component on the mounting bracket according to the real-time heating information, so that the light conditions of the first photovoltaic component and the second photovoltaic component are evenly distributed.

[0118] By adjusting the relative distance, the light conditions of the first photovoltaic module and the second photovoltaic module are evenly distributed to avoid performance degradation caused by overheating of a certain module. Uniform light conditions help improve the overall power generation efficiency of the system. Ensuring uniform temperature distribution of photovoltaic modules can reduce energy loss caused by local overheating and improve the energy conversion efficiency of the system.

[0119] By adjusting the relative distance, reducing heat transfer and avoiding local overheating, the material aging and performance degradation of photovoltaic modules caused by high temperature can be reduced. Uniform temperature distribution helps to extend the service life of photovoltaic modules. Optimized temperature management can reduce the failure rate and improve the stability and reliability of the system. Real-time monitoring and dynamic adjustment enable the system to cope with various environmental changes and ensure continuous and efficient operation.

[0120] In some embodiments, the mounting bracket includes a slide rail adjustment mechanism, and the slide rail adjustment mechanism is arranged in the first mounting area and the second mounting area; the back side of the first photovoltaic component is adjustably mounted in the first mounting area and the back side of the second photovoltaic component is adjustably mounted in the second mounting area, comprising: the back side of the first photovoltaic component and the back side of the second photovoltaic component are respectively mounted on the slide rail adjustment mechanisms in the first mounting area and the second mounting area.

[0121] The rail adjustment mechanism can precisely control the movement of the photovoltaic modules to ensure that the installation height and distance meet the calculated results. This precise control helps optimize the light transmittance and power generation efficiency of the system and reduce human errors. The rail adjustment mechanism supports dynamic adjustment and can adjust the position of the photovoltaic modules in real time according to environmental changes (such as light intensity, temperature, etc.). For example, in different seasons or time periods, the system can automatically adjust the height and spacing of the photovoltaic modules to adapt to different light conditions and temperature requirements. The rail adjustment mechanism can realize automatic adjustment, reducing manual intervention and maintenance frequency. The simple adjustment process reduces the complexity and cost of system maintenance.

[0122] The slide rail adjustment mechanism provides stable support to ensure that the photovoltaic modules will not tilt or fall off during the adjustment process, thus enhancing the safety of the system. The slide rail adjustment mechanism can accurately adjust the position of the photovoltaic modules to avoid collision and damage caused by improper position.

[0123] Exemplarily, adjusting the height of the first photovoltaic component and the second photovoltaic component on the mounting bracket according to the target height and the target distance includes: determining a first mounting height corresponding to the first photovoltaic component and a second mounting height corresponding to the second photovoltaic component according to the target height and the target distance; controlling a slide rail adjustment mechanism in the first mounting area to drive the first photovoltaic component to move according to the first mounting height; and controlling a slide rail adjustment mechanism in the second mounting area to drive the second photovoltaic component to move according to the second mounting height.

[0124] Through the automated control of the central control system and the slide rail adjustment mechanism, the photovoltaic modules can be accurately moved to the calculated target height and distance. Precise positioning helps optimize the system's light transmittance and power generation efficiency, and reduces shading and heat transfer.

[0125] The method can dynamically adjust the position of photovoltaic modules according to real-time calculation results and environmental changes. For example, in different time periods and seasons, the system can automatically adjust the height and spacing of photovoltaic modules to adapt to changes in light intensity and temperature to ensure the optimal performance of the system. The use of the slide rail adjustment mechanism simplifies the installation and maintenance process and reduces the frequency and complexity of manual operations. Through the central control system, the position of photovoltaic modules can be remotely monitored and adjusted, which improves the management efficiency of the system. The slide rail adjustment mechanism provides stable support to ensure that the photovoltaic modules will not tilt or fall off during the adjustment process, thereby enhancing the safety of the system. Through precise control, performance degradation and failure risks caused by improper position are avoided, and the reliability of the system is improved.

[0126] At the same time, the installation area can also be any one of an electric lifting mechanism and a mechanical screw rod adjustment mechanism. The electric lifting mechanism adjusts the height of the component through a motor control, has high precision, and can be combined with a sensor to achieve intelligent control. The mechanical screw rod adjustment mechanism adjusts the position of the component by rotating a manual or automatic screw rod, which is suitable for scenes that require large torque adjustment. This embodiment of the application is not limited to this.

[0129] 2. Enhanced flexibility: This method allows the transmittance of photovoltaic modules to be adjusted after installation, so that the system can be flexibly adjusted according to actual needs. For example, in different seasons or different time periods, the transmittance of photovoltaic modules can be dynamically adjusted according to the light intensity and the growth requirements of crops.

[0130] 3. Wide application scope: This method is not only applicable to agricultural photovoltaic complementary projects, but can also be widely used in scenarios such as building integrated photovoltaics (BIPV). In BIPV, light transmittance not only affects the lighting of the building, but also affects the beauty and comfort of the building. By dynamically adjusting the light transmittance, these needs can be better met.

[0131] 4. Optimize space utilization: By reasonably adjusting the position of photovoltaic modules, the utilization of space is optimized and the shading problem existing in the traditional fixed installation method is avoided. This helps to achieve higher power generation efficiency and better light transmission effect in a limited space.

[0132] 5. Improve user experience: In actual applications, users can adjust the light transmittance of the photovoltaic system according to their needs, which improves the practicality of the system and user satisfaction. Especially in buildings, the light transmittance can be flexibly adjusted according to the needs of indoor activities to improve the comfort of living and working.

[0133] 6. Reduce maintenance costs: Since the position of photovoltaic modules can be flexibly adjusted, the system can adapt to environmental changes more easily during long-term use, reducing maintenance costs caused by shading and other problems.

[0134] In summary, the photovoltaic system with adjustable transmittance and its installation method not only solve the problem of fixed transmittance of traditional photovoltaic modules, but also improve the flexibility, transmittance and power generation efficiency of the system through dynamic adjustment, and is suitable for a variety of special application scenarios.
