Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic rooftop power stations, and in particular to a method and apparatus for arranging photovoltaic support structures. Background Technology

[0002] Photovoltaic rooftop power stations are widely used on the roofs of industrial and commercial plants, residential buildings, and other buildings, offering advantages such as not occupying ground resources and flexible layout. Their support structure design must balance structural safety, power generation efficiency, and economy, with the layout of purlins, clamps, and module installation points directly affecting system stability and cost-effectiveness. However, traditional design methods have significant drawbacks. First, the design process heavily relies on manual experience and lacks automated tools, leading to inefficient purlin placement and susceptibility to positioning errors. Second, the lack of standardized purlin specifications results in material redundancy and increased procurement costs due to non-standardized design. Furthermore, multi-constraint optimization is difficult, requiring simultaneous satisfaction of multiple technical indicators such as roof tile corrugation spacing, photovoltaic module size matching, cantilever length limits, and uniform load distribution; traditional manual calculations struggle to achieve a globally optimal solution. In addition, non-standardized design results in various purlin and clamp specifications, increasing material management complexity and reducing efficiency in repetitive positioning and installation during construction, significantly driving up overall construction costs. These problems severely restrict the large-scale application of photovoltaic rooftop power stations. Summary of the Invention

[0051] Figure 3 This is a structural diagram of a photovoltaic support arrangement device provided in an embodiment of the present disclosure. Detailed Implementation

[0052] This disclosure provides a photovoltaic support arrangement method and apparatus. The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this disclosure. Furthermore, the embodiments and features described in this application can be combined with each other unless otherwise specified.

[0053] This disclosure provides a method for arranging photovoltaic support structures, such as... Figure 1 As shown, it includes:

[0054] S101. Obtain the structural parameters of the load-bearing structure;

[0055] Among them, the structural parameters of the load-bearing structure include: the dimensions of the load-bearing structure;

[0056] S102. Based on the structural parameters of the supporting structure and the pre-selected photovoltaic modules, determine the structural parameters of the photovoltaic array; wherein, the photovoltaic array includes: at least one photovoltaic module; the structural parameters of the photovoltaic array include: the dimensions of the photovoltaic array;

[0057] S103. Determine the dimensions of the photovoltaic support based on the dimensions of the photovoltaic array and the preset parameter library of standard support components for the photovoltaic support;

[0058] S104. Determine the spacing and number of photovoltaic supports based on the structural parameters of the photovoltaic array;

[0059] S105. Based on the structural parameters of the load-bearing structure, determine the connection points between the fixed structure and the load-bearing structure of the photovoltaic bracket;

[0060] S106. Determine the photovoltaic bracket layout scheme based on the size of the photovoltaic bracket, the spacing of the photovoltaic bracket, the number of photovoltaic brackets, and the connection points.

[0061] In this embodiment, the photovoltaic (PV) support structure can be applied to a rooftop PV power station. The rooftop PV power station may include a PV array, an inverter, an electrical system, and the PV support structure. The PV array is the core power generation unit of the rooftop PV power station, primarily used to convert solar energy into electrical energy. The PV support structure is mainly used to fix the PV array.

[0062] The supporting structure in this embodiment can be the roof of a building where a photovoltaic rooftop power station is installed. The photovoltaic bracket fixes the photovoltaic array to the supporting structure. The size of the supporting structure limits the size of the photovoltaic bracket installed on it, and further limits the size of the installed photovoltaic array.

[0063] Furthermore, since the size of a photovoltaic array is positively correlated with its performance indicators such as power generation, the number of photovoltaic modules in the array can be determined based on the required power generation and the pre-selected power generation of the photovoltaic modules.

[0064] The size of the photovoltaic array can be obtained by determining the arrangement of the photovoltaic modules in the array based on the number and size of the photovoltaic modules.

[0065] Furthermore, select a standard photovoltaic (PV) bracket support from the PV bracket standard support component parameter library. This library stores structural parameters for various standard PV bracket supports. Among these, a standard PV bracket support can be a standard purlin assembly of a PV bracket. A purlin (i.e., a horizontal support member) is a transverse support member that supports the PV array; a single purlin can be composed of multiple standard purlin assemblies connected together.

[0066] The number of standard purlin components for the photovoltaic support can be determined based on the lateral dimensions of the photovoltaic array using the following formula (1).

[0067]

[0068] Where N represents the number of standard purlin components in the photovoltaic support system, W represents the lateral dimension of the photovoltaic array, and L represents the length of the selected standard purlin components. The representation is rounded up.

[0069] The length of the photovoltaic bracket purlins is determined based on the number of standard purlin components, thereby determining the size of the photovoltaic bracket.

[0070] Furthermore, installation points are selected at the edges of the pre-selected photovoltaic modules and connected to the photovoltaic support structure. The installation points can be determined using methods such as stress analysis, selecting at least one pair of installation points on the edge of the photovoltaic module and its opposite edge. The pair of installation points formed by the two corresponding installation points on the two edges are connected to the same photovoltaic support structure.

[0071] Since the photovoltaic (PV) modules in a PV array are of the same type, they also have the same mounting points. The mounting points on PV modules in the same horizontal row of the PV array are connected to the same PV support structure. Based on the number of PV modules in each vertical column and the number of mounting point pairs on each PV module, the number of PV support structures connected to the PV array can be determined. Simultaneously, the spacing of the PV support structures can be determined based on the spacing of the vertical mounting points.

[0072] Furthermore, each photovoltaic (PV) bracket can include multiple fixing structures, one end of which is connected to the horizontal support member of the PV bracket. The other end of the fixing structure can be a connector that can be fixed to the load-bearing structure. Taking a metal roof as an example, the fixing structure can be a clamp that can be fixed to the metal tiles of the metal roof. By analyzing the stress on the PV array and the PV bracket, the location of the fixing structure (i.e., the connection point between the PV bracket and the load-bearing structure) can be determined. In the vertical direction, the fixing structure and the horizontal support member are on the same plane. For areas where the stress on the PV bracket is concentrated, the density of the fixing structure can be increased accordingly to improve stability.

[0073] Furthermore, based on the spacing, quantity, size, and fixed structure locations of the photovoltaic (PV) brackets obtained from the above steps, a PV bracket layout scheme is derived. This scheme can be represented as a fixed structure location diagram including coordinates, a PV module installation point diagram, and a selection scheme for standard PV bracket support components.

[0074] In summary, this disclosure achieves global optimization by incorporating key technical attributes related to the economy, safety, and standards of photovoltaic brackets, such as horizontal support components, fixing structures, and component installation points, into the same scope and considering them centrally. In particular, including horizontal support components in the standardization considerations can not only improve material utilization, reduce costs, and reduce waste, but also reduce on-site construction work and improve work efficiency.

[0075] In yet another embodiment provided in this disclosure, the photovoltaic array is connected to at least one photovoltaic support;

[0076] The photovoltaic support structure includes: horizontal support components and at least one fixing structure;

[0077] The horizontal support components of the photovoltaic bracket are connected to the photovoltaic array installation points; used to fix the photovoltaic array to the photovoltaic bracket.

[0078] The fixed structure is connected to the horizontal support member and the load-bearing structure respectively; it is used to fix the photovoltaic bracket to the load-bearing structure.

[0079] In this embodiment, the photovoltaic support structure consists of horizontal support members and a fixing structure, with the photovoltaic modules fixed to the horizontal support members. A power generation system composed of a certain number of photovoltaic modules is a photovoltaic array, and the photovoltaic modules in the array can be connected in series via electrical connections. The photovoltaic array, composed of photovoltaic modules, is fixed to the load-bearing structure by multiple photovoltaic supports.

[0080] In another embodiment provided in this disclosure, the above step S102, "determining the structural parameters of the photovoltaic array based on the structural parameters of the supporting structure and the pre-selected photovoltaic modules," can be implemented as follows:

[0081] Step 1: Using the structural parameters of the supporting structure as constraints, determine the maximum number of photovoltaic modules that the supporting structure can support based on the size of the photovoltaic modules;

[0082] Step 2: Using the maximum number of photovoltaic modules as a constraint, determine the number of photovoltaic modules according to preset target parameters; wherein, the preset target parameters include at least one of the following: target cost;

[0083] Step 3: Based on the number of photovoltaic modules, the size of the photovoltaic modules, and the predetermined arrangement of the photovoltaic modules in the photovoltaic array, obtain the size of the photovoltaic array.

[0084] In this embodiment of the disclosure, the size of the supporting structure (i.e., the roof) in the photovoltaic rooftop power station limits the size of the photovoltaic array. Based on the roof's dimensions, the roof area can be obtained, and combined with the area of ​​the photovoltaic modules, the maximum number of photovoltaic modules that can be accommodated within the roof area (i.e., the maximum number of photovoltaic modules that can be supported) can be further determined, as shown in the following formula (2).

[0085]

[0086] Among them, T max S represents the maximum number of photovoltaic modules that can be accommodated within the roof area. r S represents the area of ​​the roof. p Characterizes the area of ​​the selected photovoltaic module. The representation is rounded down. The photovoltaic modules here can be pre-selected based on specific needs in practical applications.

[0087] After determining the maximum number of photovoltaic (PV) modules that can be supported, this serves as the upper limit for the number of PV modules. However, in practical applications, the number of PV modules is limited by various factors, such as cost and the power output of the PV power plant. These limiting factors are used as preset target parameters to further restrict the number of PV modules. If the number of PV modules obtained based on the preset target parameters exceeds the maximum supported number, the maximum supported number is determined as the total number of PV modules; conversely, if the number of PV modules obtained based on the preset target parameters is less than the maximum supported number, the number of PV modules obtained based on the preset target parameters is determined as the total number of PV modules.

[0088] Furthermore, the arrangement of photovoltaic (PV) modules can be predetermined during the design process of a rooftop PV power station, based on factors such as roof shape, sunlight conditions, and space utilization. The arrangement includes the expansion direction of the PV array and the number of PV modules in each direction. Based on the arrangement, the number of PV modules can be determined, and the size of the PV array can be further determined based on the size of the PV modules. During the arrangement process, a threshold between PV modules can be introduced to ensure a reasonable spacing between them, thereby improving heat dissipation efficiency, preventing shading between modules, and increasing power generation efficiency.

[0089] In yet another embodiment provided in this disclosure, the horizontal support member includes: at least one standard photovoltaic bracket support member;

[0090] A pre-set library of standard photovoltaic (PV) bracket support components is provided, including various standard PV bracket support components; these standard PV bracket support components are sorted in descending order based on length level.

[0091] The above step S103, "Determine the size of the photovoltaic bracket based on the size of the photovoltaic array and the preset photovoltaic bracket standard support parameter library," can be executed as follows:

[0092] Step 1: Select a standard photovoltaic support component from the preset standard support component library;

[0093] Step 2: Determine the number of standard photovoltaic brackets based on the array width and the length of the selected standard photovoltaic bracket support.

[0094] Step 3: Determine the length of the horizontal support components based on the number of standard support components for the photovoltaic system;

[0095] Step 4: Determine the cantilever length of the photovoltaic bracket based on the array width and the length of the horizontal support components;

[0096] Wherein, the cantilever length is the difference between the length of the horizontal support member and the width of the array;

[0097] Step 5: When the cantilever length of the photovoltaic bracket is greater than the preset cantilever length, return to the step of selecting a standard photovoltaic bracket support from the preset photovoltaic bracket standard support library, select the photovoltaic bracket standard support for the next length level, until the cantilever length of the photovoltaic bracket is less than the preset cantilever length.

[0098] Step 6: Determine the dimensional parameters of the photovoltaic bracket based on the current length of the horizontal support components.

[0099] In this embodiment, the purlins (i.e., horizontal support members) of the photovoltaic (PV) mounting system can be composed of standard purlin assemblies (i.e., standard PV mounting system supports). The preset standard PV mounting system support library can be a database storing parameters for various standard PV mounting system supports, where different types of standard PV mounting system supports can be of different lengths. The standard PV mounting system supports in this database can be sorted according to a preset standard, which can be arranged in descending order of length.

[0100] In one possible implementation, the longest photovoltaic bracket standard support from the preset photovoltaic bracket standard support component library can be selected first. According to the above formula (1), the quantity of the selected photovoltaic bracket standard support component can be obtained, thereby obtaining the length of the currently selected horizontal support component. Further, the cantilever length of the photovoltaic bracket is obtained based on the difference between the length of the horizontal component and the length of the photovoltaic array. The obtained cantilever length is compared with the allowable range of cantilever length (i.e., the preset cantilever length). If the obtained cantilever length exceeds the preset cantilever length, the process returns to step one above to reselect a photovoltaic bracket standard support component.

[0101] The newly selected photovoltaic bracket standard support components can be sorted in descending order of length. Select the standard support component with the next lower length level and repeat steps two through five above. Continue until the obtained cantilever length is within the allowable range of cantilever length (i.e., less than the preset cantilever length). Then, perform step six above to select the currently selected photovoltaic bracket standard support component as the horizontal support component, thereby determining the length of the horizontal support component and subsequently determining the dimensions of the photovoltaic bracket.

[0102] In yet another embodiment provided in this disclosure, the photovoltaic module includes at least one pair of mounting points;

[0103] The above step S104, "determining the spacing and number of photovoltaic supports based on the structural parameters of the photovoltaic array," can be implemented as follows:

[0104] Step 1: Determine the installation locations of the photovoltaic modules; wherein, the two installation locations in the first direction are connected to the same photovoltaic bracket;

[0105] Step 2: Determine the installation locations of the photovoltaic array based on the arrangement of the photovoltaic modules in the array;

[0106] Step 3: Determine the spacing and number of photovoltaic brackets based on the installation points of the photovoltaic array; wherein, the spacing of the photovoltaic brackets is determined based on the distance between the installation points in the second direction; the number of photovoltaic brackets is determined based on the number of installation points in the second direction; the first direction is perpendicular to the second direction.

[0107] In this embodiment of the disclosure, the installation point can refer to the connection point between the photovoltaic module and the photovoltaic support. The installation point can be determined by methods such as finite element analysis, experimental testing, and formula techniques. Taking the finite element analysis method as an example, in the simulation space, a model of the photovoltaic module and the photovoltaic support is constructed, and static loads (e.g., the self-weight of the photovoltaic module, the weight of accumulated water, and the weight of accumulated snow) and dynamic loads (e.g., wind pressure) are introduced. The photovoltaic module is subjected to stress analysis, and the point that can guarantee the load requirements and ensure uniform stress distribution is selected and determined as the installation point.

[0108] Each photovoltaic (PV) module requires at least one pair of mounting points. In each pair, the two mounting points are located on opposite sides of the PV module. The line connecting the two pairs of mounting points is parallel to the other two sides of the PV module, and each pair of mounting points is connected to the same PV support structure. The direction of the line connecting the two pairs of mounting points is the first direction, and the second direction can be a direction parallel to the side containing the mounting points.

[0109] Since photovoltaic modules in the same photovoltaic array can be of the same specifications, the total number of installation points in the entire photovoltaic array can be determined based on the installation points of the photovoltaic modules as described above. All installation points on the same line in the first direction are connected to the same photovoltaic support. Furthermore, the number of photovoltaic supports connected to the photovoltaic array can be determined based on the number of installation points in the second direction. The spacing of the photovoltaic supports connected to the photovoltaic array can be determined based on the spacing of the installation points in the second direction.

[0110] In another embodiment provided in this disclosure, the fixed structure and the horizontal support member are aligned in the vertical direction.

[0111] In this embodiment of the disclosure, the fixed structure and the horizontal support member can be in the same plane in the vertical direction, wherein the vertical direction refers to the direction perpendicular to the photovoltaic array.

[0112] In yet another embodiment provided in this disclosure, the structural parameters of the load-bearing structure further include: the position of the corrugation peak of the load-bearing structure;

[0113] The position of the corrugated peak of the load-bearing structure corresponds to the position of the fixed structure.

[0114] In this embodiment, the corrugation position of the supporting structure refers to the corrugation position of the roof tiles on the roof where the photovoltaic rooftop power station is installed. In actual implementation, to ensure the lighting effect of the photovoltaic rooftop power station and the fixing effect of the photovoltaic bracket, the photovoltaic bracket can be fixed at the corrugation position of the roof tiles. The number of fixing structures is determined based on the number of corrugations of the roof tiles within the coverage area of ​​the photovoltaic array, and the fixing structures are matched with the corrugation positions of the roof tiles so that the fixing structures can be fixed at the corrugation positions of the roof tiles. This method can avoid installation errors and improve on-site construction efficiency.

[0115] Furthermore, in cases where there is no fixed structure under the photovoltaic modules, additional fixed structures can be added to ensure that each photovoltaic module has at least one fixed structure. Optionally, stress analysis can be performed on the combination of the photovoltaic array, photovoltaic support, and load-bearing structure to identify high-load areas, and the density of fixed structures can be increased in these areas to improve safety.

[0116] In yet another embodiment provided in this disclosure, the photovoltaic support arrangement method further includes,

[0117] Step 1: Obtain multiple photovoltaic support layout schemes;

[0118] Step 2: For multiple photovoltaic support layout schemes, the target photovoltaic support layout scheme is obtained by using a preset optimization algorithm based on preset constraints.

[0119] Among them, the preset optimization algorithm includes: particle swarm optimization algorithm.

[0120] In this embodiment, multiple photovoltaic (PV) support arrangement methods meeting various constraints can be pre-obtained and input into a particle swarm optimization (PSO) algorithm to determine the fitness of each particle. The particle encoding can include PV support dimensions, spacing, number of supports, and connection points; cantilever length, peak spacing matching degree, and module spacing limits are used as constraints. Particles violating these constraints are penalized, reducing their fitness. The particle with the highest fitness is then output as the target PV support arrangement method. The final arrangement scheme can be output as a layout diagram. Based on the obtained PV support dimensions, spacing, number, and connection points, a corresponding layout diagram is generated to guide actual construction.

[0121] In yet another embodiment provided in this disclosure, the preset optimization algorithm includes: particle swarm optimization algorithm;

[0122] The preset constraints include: cantilever length, the correspondence between the corrugation peaks and the fixed structure, and the spacing between photovoltaic modules.

[0123] In this embodiment of the disclosure, the particle swarm optimization algorithm can be an algorithm that evaluates the merits of particle positions using a fitness function, and can determine the optimal solution within the particle swarm. This embodiment of the disclosure utilizes this algorithm, treating each obtained photovoltaic support arrangement method as a particle, to find the optimal solution among multiple photovoltaic support arrangement methods.

[0124] This provides, for example Figure 2 The photovoltaic module layout shown is used as an example. The photovoltaic array 5 is set on the supporting structure 2; the horizontal support member 6 is connected to the photovoltaic module 1 through the installation point 4; the horizontal support member 6 is connected to the supporting structure 2 through the fixing structure 3.

[0125] This disclosure also provides a photovoltaic support arrangement device, such as Figure 3 As shown, it includes:

[0126] The parameter acquisition module 301 is used to acquire the structural parameters of the load-bearing structure; wherein, the structural parameters of the load-bearing structure include: the dimensions of the load-bearing structure.
