[0002] Photovoltaic (PV) modules are widely used in daily life and production. Related technologies primarily select the most suitable PV array layout based on information about the location and area where the PV modules are installed, aiming to maximize power generation performance. However, during actual installation, when obstacles are encountered, most adjustments are made based on manual experience, such as removing one or more PV modules located under the obstacle. While this method allows the PV array to better fit the installation environment after removing some modules, it also significantly reduces the number of PV modules in the final array, limiting the installed capacity. This is especially true in complex installation environments, where the number of PV modules that need to be removed further increases, thus significantly impacting the power generation performance of the PV array.

[0022] Remove the first element located within the area affected by the obstacle from the plurality of first elements to obtain the plurality of second elements.

[0055] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0056] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0057] The photovoltaic module arrangement method, photovoltaic module arrangement device, photovoltaic system, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0058] The arrangement method of photovoltaic modules can be applied to the terminal, and can be executed by the hardware or software in the terminal.
[0059] The photovoltaic module arrangement method provided in this application embodiment can be implemented by a photovoltaic system or a functional module or entity in the photovoltaic system that can realize the photovoltaic module arrangement method. The photovoltaic system is used as the implementing entity to illustrate the photovoltaic module arrangement method provided in this application embodiment.
[0060] like Figure 1 As shown, the arrangement method of the photovoltaic module includes steps 110, 120 and 130.
[0061] Step 110: Divide each photovoltaic module in the standard array along the first direction to obtain multiple first elements; the standard array includes at least one row of photovoltaic modules arranged sequentially based on the second direction, the first direction and the second direction being perpendicular to each other;
[0062] In this step, the first direction and the second direction are two mutually perpendicular directions on the same plane.
[0063] For example, if the first direction is north-south, the second direction can be east-west; or, if the first direction is east-west, the second direction can be north-south.
[0064] Of course, in other embodiments, the first direction and the second direction can also be any other direction, which is not limited here.
[0065] Standard photovoltaic arrays are photovoltaic arrays with regular shapes, such as rectangular or square photovoltaic arrays.
[0066] It is understood that a standard array includes at least one row of a first number of photovoltaic modules arranged sequentially in a second direction. The photovoltaic modules in different rows may be placed in the same or different directions.
[0067] The first quantity is an integer value greater than or equal to 1.
[0068] For example, photovoltaic modules may be placed horizontally or vertically, but photovoltaic modules in the same row are placed in the same direction.
[0069] The standard array can be any array arrangement, and this application does not limit it.
[0070] In actual implementation, settings can be made based on the actual terrain conditions or other configuration requirements.
[0071] In some embodiments, the standard array may include, but is not limited to: an array with one vertical row, an array with two vertical rows, an array with three vertical rows, an array with three vertical rows and one horizontal row, an array with four vertical rows, an array with four vertical rows and one horizontal row, or an array with five vertical rows; wherein, the number before the vertical row is used to represent the number of vertically placed photovoltaic modules arranged along the first direction, and the number before the horizontal row is used to represent the number of horizontally placed photovoltaic modules arranged along the first direction, etc.
[0072] In this embodiment, the number preceding "vertical" indicates the number of vertically placed photovoltaic modules arranged sequentially along the first direction, such as... Figure 2 An example of a three-row array is provided, in which three photovoltaic modules are placed vertically along a first direction.
[0073] The number preceding "horizontal row" indicates the number of horizontally placed photovoltaic modules arranged sequentially along the first direction, such as... Figure 3 An example of an array with three vertical rows and one horizontal row is given, wherein three photovoltaic modules are placed vertically in the first direction and one photovoltaic module is placed horizontally.
[0074] In actual implementation, the best standard array layout can be selected based on the actual terrain conditions or other setup requirements.
[0075] The method for determining the standard array layout will be explained below, and will not be repeated here.
[0076] In this application, for all photovoltaic modules corresponding to the same row, each first element obtained by dividing them should be an element with the same shape and size; and the area of each first element is smaller than the area of a single photovoltaic module.
[0077] For photovoltaic modules that correspond to different rows, the classification methods may be the same or different.
[0078] Figure 4 An example of a partitioning method is given, in which each photovoltaic module is divided into three first elements along the north-south direction.
[0079] It should be noted that in this application, the division direction of the photovoltaic modules should be consistent with the first direction.
[0080] For example, for Figure 3 For vertically installed photovoltaic modules, the dividing direction should be north-south; for Figure 3 For photovoltaic modules arranged horizontally in the middle, the dividing direction should also be north-south.
[0081] In some embodiments, dividing each photovoltaic module in a standard array along a first direction may include dividing each photovoltaic module corresponding to at least a portion of the rows along the first direction.
[0082] At least some of the rows consist of one or more rows.
[0083] In some embodiments, step 110 may include:
[0084] The target quantity is determined based on at least one of computation time and hardware performance.
[0085] The photovoltaic modules are divided proportionally into the first element of the target quantity along the first direction.
[0086] In this embodiment, the target number is the number of elements obtained by dividing a single photovoltaic module.
[0087] It is understandable that the target number of photovoltaic modules in different rows may be the same or different.
[0088] For example, the coordinates of any photovoltaic module can be represented as (x0, y0), (x0, y1), (x1, y1), and (x1, y0). Then, based on the computation time or the computer's performance, the target quantity m is determined. Based on this target quantity m, the photovoltaic modules are divided along the first direction, resulting in the following... Figure 5 The diagram shows the multiple first elements after the partitioning.
[0089] According to the photovoltaic module arrangement method provided in the embodiments of this application, the photovoltaic modules are divided based on at least one of computing time and hardware performance. The division ratio can be flexibly adjusted according to actual needs to obtain the optimal number of first elements, realizing the dynamic division of photovoltaic modules, and has high flexibility, practicality and versatility.
[0090] Step 120: Based on the obstacle information of the target area, filter multiple first elements to obtain multiple second elements;
[0091] In this step, the target area is the area where the photovoltaic modules are to be installed.
[0092] For example, the target area can be a rooftop, balcony, or any other location; this application makes no limitation on this.
[0093] Obstacle information is used to characterize the shading situation in the target area or various obstacles that affect the placement of photovoltaic modules.
[0094] The second element is the element remaining after filtering multiple first elements.
[0095] It is understandable that the second element is the first element among multiple first elements that is not affected by obstacles.
[0096] In this step, multiple first elements are filtered based on the obstacle information of the target area. This can eliminate some first elements that cannot be installed due to the influence of obstacles, so that the area corresponding to the remaining first elements is an area that is not affected by obstacles and can be installed normally.
[0097] In some embodiments, step 120 may include:
[0098] Based on obstacle information, the standard layout array is divided into at least two regions, and at least one of the two regions is an area affected by obstacles;
[0099] Remove the first element located within the area affected by the obstacle from multiple first elements to obtain multiple second elements.
[0100] In this embodiment, at least two regions should include at least one region affected by an obstacle and at least one region unaffected by an obstacle.
[0101] The area affected by the obstacle may include, but is not limited to, the area where the obstacle itself is located and the shadow area created by the obstacle.
[0102] like Figure 6As shown, the standard array includes five regions. The regions enclosed by the dashed boxes at the four corners are the regions affected by obstacles, while the other regions are the regions unaffected by obstacles.
[0103] In actual implementation, each photovoltaic module in the standard array can be divided based on step 110 to obtain multiple first elements, and then combined with... Figure 6 By partitioning multiple first elements into five regions, we can obtain the following: Figure 7 The results shown are for reference. Figure 7 It can be seen that for all the first elements obtained, some of the first elements are located in the region unaffected by obstacles, while the remaining first elements are located in the region affected by obstacles.
[0104] In obtaining such Figure 7 After the division results shown, elements located within the obstacle-affected area are removed from all the first elements, and elements located within the obstacle-free area are retained. At least a portion of the retained first elements constitute multiple second elements, such as... Figure 8 As shown.
[0105] Figure 10 Another partitioning scenario is illustrated, where the standard array comprises two regions: a concave region within the dashed box and a rectangular region outside the concave region. The concave region is unaffected by obstacles, while the rectangular region is affected by obstacles.
[0106] In the Figure 10 After dividing the photovoltaic modules in the standard array shown, combined with Figure 10 The two regions shown can be obtained as follows: Figure 11 The division results shown are for reference. Figure 11 It can be seen that for all the first elements obtained, some of the first elements are located within the concave region, while the remaining first elements are located outside the concave region.
[0107] Continue to refer to Figure 11 Then, remove the first elements located outside the concave region from all the first elements, and keep the first elements located within the concave region to obtain multiple second elements.
[0108] According to the photovoltaic module arrangement method provided in the embodiments of this application, by dividing the photovoltaic module into smaller first elements and then deleting the elements located in the area affected by obstacles from the obtained multiple first elements, the influence of obstacles can be refined, thereby further improving the installed capacity.
[0109] Step 130: Adjust the standard layout array based on multiple second elements to obtain the optimized layout array.
[0110] In this step, the optimized array arrangement is the new array of photovoltaic modules obtained after adjusting the arrangement of the photovoltaic modules based on the overall situation of the second element.
[0111] Optimized array layouts have higher installed capacity, resulting in higher power generation.
[0112] The implementation of step 130 will be explained below from two different application scenarios.
[0113] Firstly, a scene with vertically arranged rectangular rooftops.
[0114] Continue to refer to Figure 8 After obtaining the remaining second elements, the photovoltaic modules are rearranged based on these second elements, so that the total area of all rearranged photovoltaic modules approaches the total area of all second elements, thereby expanding the installed capacity of the photovoltaic modules. The final result is as follows: Figure 9 (b) shows the optimized layout array.
[0115] Continue to refer to Figure 9 ,in, Figure 9 (a) illustrates a conventional array arrangement, by comparison Figure 9 (a) and Figure 9 (b) It is known that, through the method of steps 110-130 of this application, the total number of photovoltaic modules in the photovoltaic array under this scenario can be increased from 58 to 60, effectively improving the installed capacity of photovoltaic modules.
[0116] Secondly, the scene of horizontally arranged irregularly shaped roofs.
[0117] Continue to refer to Figure 11 After obtaining the remaining second elements, the photovoltaic modules are rearranged based on these second elements, so that the total area of all rearranged photovoltaic modules approaches the total area of all second elements, thereby expanding the installed capacity of the photovoltaic modules. The final result is as follows: Figure 12 (b) shows the optimized layout array.
[0118] Continue to refer to Figure 12 ,in, Figure 12 (a) illustrates a conventional array arrangement, by comparison Figure 12 (a) and Figure 12 (b) It is known that by using the method of steps 110-130 of this application, the total number of photovoltaic modules in the photovoltaic array under this scenario can be increased by 1, thereby increasing the installed capacity of the photovoltaic modules.
[0119] Of course, the methods provided in this application can also be applied to other scenarios, which will not be elaborated here.
[0120] In this application, based on a standard array layout, individual photovoltaic modules are divided into multiple first elements. Based on obstacle information of the target area, elements that cannot be installed due to obstacles are removed from the multiple first elements to obtain the remaining second elements that are not affected by obstacles. The photovoltaic modules are then rearranged based on the second elements so that the total area of the rearranged photovoltaic modules is close to the total area of the second elements, thereby improving space utilization efficiency, increasing the installed capacity of photovoltaic modules, and thus increasing the power generation of the final optimized array layout.
[0121] According to the photovoltaic module arrangement method provided in the embodiments of this application, a single photovoltaic module is divided into elements to obtain multiple second elements that are not affected by obstacles. Then, the photovoltaic modules are rearranged based on the multiple second elements so that the total area of the rearranged photovoltaic modules is close to the total area of the second elements. This can maximize the refinement of the impact of obstacles to improve space utilization efficiency, increase the installed capacity of photovoltaic modules, and thus increase the power generation of the final optimized array. This solves the technical problem of limited installed capacity in related technologies. Moreover, it is applicable to any installation scenario and various installation schemes, and has universality and applicability.
[0122] In some embodiments, step 130 may include:
[0123] Based on the second element corresponding to the target row in at least one row, determine the second number of photovoltaic modules corresponding to the target row; replace the first number of photovoltaic modules corresponding to the target row with the second number of photovoltaic modules to obtain an optimized array. In this embodiment, the target row can be any row in at least one row.
[0124] The second quantity is the number of photovoltaic modules included in each row of the optimized array.
[0125] It is understandable that the second quantity may be the same as or greater than the first quantity.
[0126] In this embodiment, the photovoltaic modules can be rearranged row by row. By calculating the optimal number of photovoltaic modules for each row, the optimal array layout can be determined, resulting in higher computational accuracy and precision.
[0127] In some embodiments, determining the second number of photovoltaic modules corresponding to the target row based on the second element corresponding to the target row in at least one row may include:
[0128] Arrange the second elements corresponding to the target row sequentially along the second direction to obtain the sequence of the second elements corresponding to the target row;
[0129] The second quantity is determined based on the first length of the second element sequence along the second direction and the size of the photovoltaic module.
[0130] In this embodiment, the second element sequence is a set of consecutive second elements. Step 120 can be used to obtain the distribution of the second elements after removing the influence of obstacles. Then, all the second elements corresponding to each row are obtained. The consecutive second elements in each row are divided into a set. The second elements in the set are sorted in order from left to right (i.e. along the second direction) to obtain the set of consecutive second elements.
[0131] Continue with Figure 5 The photovoltaic module shown is used as an example for explanation.
[0132] For any photovoltaic module, it can be represented by the coordinates of its four vertices: (x0, y0), (x0, y1), (x1, y1), (x1, y0); then the coordinates of the first element obtained by dividing the photovoltaic module can be represented as:
[0133] elementLength = (x1 - x0) / m;
[0134] Y = y1 - y0;
[0135] Where elementLength is the length of any element along the second direction, Y is the length of the second element along the first direction, and m is the target quantity.
[0136] Based on the length of the second element along the first and second directions, the coordinates of the four corners of each second element can be represented respectively; for each consecutive set of second elements, the coordinates of the four corners corresponding to each second element in the consecutive set of second elements can be obtained.
[0137] For example, the coordinates of the four corners corresponding to the first second element in the set of consecutive second elements can be: (x0,y0), (x0,y1), (x1,y1), (x1,y0); the coordinates of the four corners corresponding to the last second element in the set of consecutive second elements can be: (x2,y0), (x2,y1), (x3,y1), (x3,y0).
[0138] In some embodiments, determining the second quantity based on the first length of the second element sequence along the second direction and the size of the photovoltaic module may include:
[0139] The second quantity is determined by the quotient of the first length and the second length of the photovoltaic module along the second direction.
[0140] In this embodiment, when the first length is an east-west length, the second length is also an east-west length.
[0141] The first length can be determined by the following steps:
[0142] Obtain the vertex coordinates of the second element at the beginning and end of the second element sequence respectively;
[0143] The first length is determined based on the vertex coordinate information.
[0144] Continuing with the example of the consecutive second element set, for each consecutive second element set, we can extract the coordinates of the four corners corresponding to the leftmost second element: (x0, y0), (x0, y1), (x1, y1), (x1, y0); and the coordinates of the four corners corresponding to the rightmost second element: (x2, y0), (x2, y1), (x3, y1), (x3, y0). Then we can obtain that the x-coordinate of the leftmost vertex of the consecutive second element set is x0, and the x-coordinate of the rightmost vertex is x3. That is, the first length of the consecutive second element set is: x3-x0. Then we can calculate the second number of photovoltaic modules that can be arranged with this length: (x3-x0) / L rounded down, where L is the second length of the photovoltaic module.
[0145] For example, continue to refer to Figure 8 After obtaining the remaining second elements, the photovoltaic modules in each row are rearranged based on the second element, so that the total area of all photovoltaic modules in that row approaches the total area of all second elements in that row, thereby increasing the installed capacity of the photovoltaic modules in that row. The final result is as follows: Figure 9 (b) shows the optimized layout array.
[0146] like Figure 9 As shown in (b), the first row of the optimized array includes nine vertically placed photovoltaic modules, relative to... Figure 9 (a) shows a conventional array layout with one additional photovoltaic module added to the first row; continue to refer to Figure 9 (b) The last row of the optimized array includes 12 vertically placed photovoltaic modules, relative to... Figure 9 (a) shows a conventional array layout with one additional photovoltaic module added to the last row.
[0147] Continue to refer to Figure 11 By rearranging the elements, the final result is as follows: Figure 12 (b) shows the optimized layout array.
[0148] like Figure 12 As shown in (b), the fourth row of the optimized array includes four horizontally placed photovoltaic modules, relative to... Figure 12 (a) shows a conventional array layout, with one photovoltaic module added to the fourth row, which also increases the installed capacity of the photovoltaic modules.
[0149] According to the photovoltaic module arrangement method provided in the embodiments of this application, the optimal number of photovoltaic modules in each row is calculated by rearranging the photovoltaic modules row by row to determine the optimal arrangement array. This method has higher calculation accuracy and can effectively improve the installed capacity of photovoltaic modules, thereby increasing the power generation of the final optimized arrangement array.
[0150] like Figure 13 As shown, in some embodiments, prior to step 110, the method may further include:
[0151] Obtain terrain information for the target area;
[0152] Based on terrain information, a standard layout array is obtained from multiple candidate layout arrays.
[0153] In this embodiment, the target area is the area where the photovoltaic module is to be installed.
[0154] For example, the target area can be a rooftop, balcony, or any other location; this application makes no limitation on this.
[0155] Terrain information includes the shape, area, and side length of the target area.
[0156] In some embodiments, the multiple candidate arrangement arrays may include, but are not limited to: an array corresponding to one vertical row, an array corresponding to two vertical rows, an array corresponding to three vertical rows, an array corresponding to three vertical rows and one horizontal row, an array corresponding to four vertical rows, an array corresponding to four vertical rows and one horizontal row, or an array corresponding to five vertical rows, etc.
[0157] Of course, in other embodiments, the candidate arrangement array can also be presented in other arrangement forms, which can be set according to the actual situation, and this application does not limit it.
[0158] The following description uses the roof as an example to illustrate the implementation of this embodiment.
[0159] Determine the installation scheme for the first direction of the roof (hereinafter, the north-south direction is taken as an example) and the installation scheme for the second direction of the roof (hereinafter, the east-west direction is taken as an example).
[0160] To determine the number of photovoltaic modules that can be installed in the north-south direction, we can find the candidate array that is less than or equal to the north-south length of the roof and is closest to the north-south length of each candidate array based on the north-south length of the roof.
[0161] To determine the number of photovoltaic modules that can be installed in the east-west direction, given an east-west length of L, a long side of the photovoltaic modules being a, a short side being b, and a spacing of c between the photovoltaic modules, the number n of photovoltaic modules in the east-west direction can be determined by the following formula:
[0162] Number of vertically arranged photovoltaic modules: n*b+(n-1)*c≤L;
[0163] The number of horizontally arranged photovoltaic modules: n*a+(n-1)*c≤L;
[0164] Where a, b, c, L and n are all greater than or equal to zero, and n is an integer.
[0165] Then, by combining the number of photovoltaic modules that can be installed in the north-south direction and the number of photovoltaic modules that can be installed in the east-west direction, the standard array layout can be determined.
[0166] Of course, in other embodiments, other feasible methods may be used to determine the standard array layout, and this application does not limit it.
