As shown in fig. 1, the arrangement method of the photovoltaic module includes: step 110, step 120 and step 130.
Step 110, dividing each photovoltaic module in the standard arrangement array along a first direction to obtain a plurality of first elements; the standard arrangement array comprises at least one row of first number of photovoltaic modules which are sequentially arranged based on a second direction, and the first direction is mutually perpendicular to the second direction;
in this step, the first direction and the second direction are two directions perpendicular to each other on the same plane.
For example, in the case where the first direction is the north-south direction, the second direction may be the east-west direction; alternatively, in the case where the first direction is the east-west direction, the second direction may be the north-south direction.
Of course, in other embodiments, the first direction and the second direction may be any other directions, which is not limited herein.
The standard arrangement array is a photovoltaic arrangement array with a regular shape, such as a rectangular or square photovoltaic arrangement array.
It is understood that the standard routing array includes at least one row of a first number of photovoltaic modules sequentially routed based on the second direction. The placement directions of the photovoltaic modules corresponding to different rows may be the same or may be different.
Wherein the first number is an integer value of 1 or more.
For example, the direction of placement of the photovoltaic modules may be horizontal or vertical, but the direction of placement of the photovoltaic modules in the same row is the same.
The standard array may be any array, and is not limited herein.
In actual execution, the settings may be based on actual terrain conditions or other setting requirements.
In some embodiments, the standard arrangement array may include, but is not limited to: an array corresponding to one vertical row, an array corresponding to two vertical rows, an array corresponding to three vertical rows and one horizontal row, an array corresponding to four vertical rows and one horizontal row, or an array corresponding to five vertical rows; the numbers in front of the vertical rows are used for representing the number of the vertically placed photovoltaic modules arranged along the first direction, the numbers in front of the horizontal rows are used for representing the number of the horizontally placed photovoltaic modules arranged along the first direction, and the like.
In this embodiment, the numbers preceding the vertical rows are used to characterize the number of vertically placed photovoltaic modules that are sequentially arranged along a first direction, as illustrated in fig. 2 for a corresponding array of three vertical rows, where there are three photovoltaic modules vertically placed along the first direction.
The numbers before the horizontal rows are used to characterize the number of photovoltaic modules placed horizontally and arranged in sequence along a first direction, as illustrated in fig. 3, an array corresponding to three vertical rows and one horizontal row is illustrated, where three photovoltaic modules are placed vertically in the first direction, and one photovoltaic module is placed horizontally.
In the actual implementation process, the optimal standard arrangement array can be selected based on the actual topography or other setting requirements.
The manner in which the array is arranged in the standard manner will be described below and will not be described in detail herein.

For the photovoltaic modules corresponding to different rows, the dividing modes may be the same or different.
Fig. 4 illustrates a division manner in which each photovoltaic module is divided into 3 first elements in the north-south direction.
In this application, the dividing direction of the photovoltaic module should be consistent with the first direction.
For example, for the photovoltaic module vertically arranged in fig. 3, the dividing direction should be the north-south direction; for the photovoltaic module arranged laterally in fig. 3, the dividing direction should also be the north-south direction.

In this embodiment, the target number is the number of elements divided by the individual photovoltaic modules.
It is understood that the number of targets for which the photovoltaic modules in different rows correspond may be the same or may be different.
For example, for any one photovoltaic module, the coordinates of its four corners can be expressed as: (x) 0 ,y 0 )、(x 0 ,y 1 )、(x 1 ,y 1 )、(x 1 ,y 0 ). And then determining a target number m according to the calculation time or the computer and the performance thereof, and dividing the photovoltaic module along a first direction based on the target number m to obtain a plurality of divided first elements as shown in fig. 5.
According to the arrangement method of the photovoltaic modules, the photovoltaic modules are divided based on at least one of calculation time and hardware performance, the dividing proportion can be flexibly adjusted based on actual requirements to obtain the optimal number of first elements, dynamic division of the photovoltaic modules is achieved, and the arrangement method has high flexibility, practicability and universality.
Step 120, screening the plurality of first elements based on the obstacle information of the target area to obtain a plurality of second elements;
in this step, the target area is an area where the photovoltaic module is to be disposed.
For example, the target area may be a roof, balcony, or any other location, without limitation.
The obstacle information is used for representing shadow shielding conditions of a target area or various obstacle conditions affecting the placement of the photovoltaic module.
The second element is the element remaining after the screening of the plurality of first elements.
It is understood that the second element is a first element of the plurality of first elements that is not affected by the obstacle.
In this step, the plurality of first elements are screened based on the obstacle information of the target area, and the first elements which are partially affected by the obstacle and cannot be installed can be removed, so that the area corresponding to the remaining first elements is an area which is not affected by the obstacle, and the installation can be performed normally.

Wherein the area affected by the obstacle may include, but is not limited to: the area where the obstacle itself is located, a shadow area generated by the obstacle, and the like.
As shown in fig. 6, the standard arrangement array includes five areas, wherein the areas surrounded by the dashed boxes at the four corners are areas affected by the obstacle, and the areas other than the four corner areas are areas not affected by the obstacle.
In the actual implementation process, each photovoltaic module in the standard arrangement array may be divided based on step 110 to obtain a plurality of first elements, and then the plurality of first elements are partitioned by combining the five regions in fig. 6, so that the result shown in fig. 7 may be obtained, and as can be seen from fig. 7, for all the obtained first elements, a part of the first elements are located in the region not affected by the obstacle, and the rest of the first elements are located in the region affected by the obstacle.
After the division result shown in fig. 7 is obtained, elements in the area affected by the obstacle are removed from all the first elements, elements in the area not affected by the obstacle are reserved, and at least part of the reserved first elements are a plurality of second elements, as shown in fig. 8.
Fig. 10 illustrates another division case in which the standard arrangement array includes two regions, which are a concave region within a dotted line frame and a rectangular region outside the concave region, wherein the concave region is a region not affected by an obstacle, and the rectangular region is a region affected by an obstacle.
After dividing the photovoltaic modules in the standard arrangement array shown in fig. 10, the dividing result shown in fig. 11 can be obtained by combining the two areas shown in fig. 10, and referring to fig. 11, it can be known that, for all the obtained first elements, part of the first elements are located in the concave area, and the rest of the first elements are located outside the concave area.
With continued reference to fig. 11, the first elements outside the concave region are then removed from all the first elements, and the first elements inside the concave region are retained, thereby obtaining a plurality of second elements.
According to the arrangement method of the photovoltaic module, the photovoltaic module is divided into smaller first elements, and then elements in the area affected by the obstacle are deleted from the acquired plurality of first elements, so that the influence refinement of the obstacle can be realized, and the installed capacity is further improved.
And 130, adjusting the standard arrangement array based on the plurality of second elements to obtain an optimized arrangement array.
In the step, the optimized arrangement array is an arrangement array of the new photovoltaic module obtained after the arrangement of the photovoltaic module is adjusted based on the overall condition of the second element.
The optimized arrangement array has higher installed capacity, so that higher generated energy is provided.
The implementation of step 130 is described below separately from two different application scenarios.

With continued reference to fig. 9, fig. 9 (a) illustrates a conventional arrangement array, and comparing fig. 9 (a) with fig. 9 (b) shows that, by the method of steps 110-130 of the present application, the total number of photovoltaic modules in the photovoltaic array in this scenario can be increased from 58 blocks to 60 blocks, so as to effectively improve the installed capacity of the photovoltaic modules.

Of course, the method provided in the present application may also be applied to any other scenario, and this application is not repeated herein.
In the application, on the basis of a standard arrangement array, a plurality of first elements are obtained by dividing a single photovoltaic module, and based on barrier information of a target area, the elements which are affected by barriers and cannot be installed are removed from the plurality of first elements to obtain the remaining second elements which are not affected by the barriers, so that the photovoltaic module is rearranged based on the second elements, the total area of the arranged photovoltaic module is close to the total area of the second elements, the space utilization efficiency is improved, the installed capacity of the photovoltaic module is improved, and the finally obtained generating capacity of the optimized arrangement array is improved.
According to the arrangement method of the photovoltaic modules, the elements of the single photovoltaic module are divided to obtain the plurality of second elements which are not influenced by the obstacles, and then the photovoltaic modules are rearranged based on the plurality of second elements, so that the total area of the arranged photovoltaic modules is close to the total area of the second elements, the influence of the obstacles can be thinned to the greatest extent, the space utilization efficiency is improved, the installed capacity of the photovoltaic modules is improved, the generated energy of the finally obtained optimally arranged array is improved, and the technical problem of limited installed capacity in the related art is solved; the method is suitable for any installation scene and various installation schemes, and has universality and universality.

The second number is the number of photovoltaic modules included in each row in the optimized array.
It will be appreciated that the second number may be the same as the first number or may be greater than the first number.

number of vertical row photovoltaic modules: n is equal to or less than b+ (n-1) c is equal to or less than L;
number of photovoltaic modules in row: n is a+ (n-1) c is less than or equal to L;
wherein, a, b, c, L and n are both greater than or equal to zero, and n is an integer.
