Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, fig. 1 shows a flowchart of steps of a solar cell matching method in an embodiment of the present invention. The method is used for selecting solar cell pieces to be put in for the solar cell modules required in the order of the solar cell modules.

Step 101, grouping orders of a plurality of solar cell modules to obtain at least one initial order group; each of the orders in the initial order group has the same grouping parameters; the grouping parameters include: solar module type, bill of materials parameters of the solar module; the order, comprising: total power, power of the solar cell module; the power of the solar cell module includes: at least one of high power, medium power, and low power.

In an embodiment of the present invention, the order of each solar cell module may include: the total power required for the order, and the power of the individual solar cell modules in the order. The power of the solar cell module may include: at least one of high power, medium power, and low power.

For example, order a for solar cell assemblies may include: the total power is 1.0001MW, the high-grade power is: 375W, mid range power: 370W, low power is: 365W.1MW = 1000000W.

The order for each solar cell module may further include: grouping parameters. The grouping parameters may include: cell type, bill of materials parameters of solar cell module. The bill of materials parameters of the solar cell module may include: back plate, back plate color, voltage, frame size, frame color, glass thickness, glass process, glue film, junction box, length of junction box, junction box terminal type, etc. The solar module types may include: PE (monolithic solar cell module), BP (double-sided double-glass solar cell module), etc. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, under the condition that a plurality of orders of solar cell modules exist, the orders with the same grouping parameters can be divided into an initial order group. Specifically, orders with the same type of solar cell modules in each order can be divided into a large group, and then in each large group, the same parameters of the bill of materials of the solar cell modules in the large group are divided into a small group according to the parameters of the bill of materials of the solar cell modules in the order, so that an initial order group is obtained.

And 102, ordering orders of the solar cell modules according to a preset rule to obtain an ordering number.

In the embodiment of the present invention, the preset rule may be: the order of the battery assembly can be prioritized, and/or a rule of the order of the battery assembly corresponding to the efficiency value of the battery piece is displayed. After sorting according to the preset rule, the obtained sorting number may have a higher priority with a smaller number, and/or the efficiency value of the battery piece corresponding to the order of the battery assembly may be smaller.

In an embodiment of the present invention, optionally, referring to fig. 2, fig. 2 shows a flowchart of steps for ordering according to a preset rule in an embodiment of the present invention. The step 102 may include:

and step 1021, initially ordering the orders of all the solar cell modules according to the order of the orders of the solar cell modules from high to low.

Step 1022, for orders of the solar cell modules with the same priority, re-ordering the orders according to the order from low to high of the efficiency values of the cell sheets corresponding to the orders, so as to obtain an ordering number.

Specifically, the priority of the order of the solar cell module may be a profit margin size capable of representing the order, and/or a customer importance level corresponding to the order. The higher the priority of the order for the solar module can be considered: the greater the profit margin of the order for the solar cell module and/or the more important the customer for the order for the solar cell module, etc.

The priority of the order of the solar cell module is presented at the same time: when the profit margin of the order of the solar cell module and the importance level of the customer corresponding to the order of the solar cell module are equal, a preset weight may be set for the profit margin of the order of the solar cell module and the importance level of the customer corresponding to the order of the solar cell module, the profit margin of the order of the solar cell module and the importance level of the customer corresponding to the order of the solar cell module are calculated according to the preset weights, and the priority of the order of the solar cell module is determined according to the order from the large to the small of the weighted values. The preset weight can be determined according to actual needs. Or, the order of the solar cell module can be sorted according to the order from the big profit margin to the small profit margin, and the rank number from the big profit margin to the small profit margin is obtained; for the ranking with the same profit margin, the ranking can be further performed according to the order of the solar cell module, and the priority of the order of the solar cell module is finally obtained. Or, the orders of the clients corresponding to the orders of the solar cell modules can be ordered according to the order from high to low, so that the orders from high to low in the importance degree are obtained; for ranking numbers with the same importance degree, ranking can be further performed according to the order of the solar cell module from big to small in profit margin, and ranking is performed according to the order of the solar cell module from big to small in profit margin, so that the priority of the order of the solar cell module is finally obtained. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, the efficiency value of the battery piece corresponding to the order can be determined according to the type of the solar battery component, the bill of materials parameter of the solar battery component and the like in the order.

In the embodiment of the invention, the orders of all the solar cell modules can be initially ordered according to the order of the orders of all the solar cell modules from high to low. Then, orders of the solar cell modules with the same priority can be sorted according to the order from low to high of the efficiency values of the cell sheets corresponding to the orders in the orders of the solar cell modules, and a sorting number is obtained. In the process of matching solar cells subsequently, the solar cells with low efficiency values can be preferentially consumed according to the sequence from small to large in sequence numbers, byproducts can be reduced to a certain extent, and resource waste and invalid output can be avoided to a great extent.

It should be noted that the above steps 101 and 102 may be performed simultaneously, or the step 102 may be performed before the step 101, or the like. In the embodiment of the present invention, the execution sequence of step 101 and step 102 is not limited.

Step 103, sequentially determining the assembly orders corresponding to the sequencing numbers according to the sequence from the small sequencing numbers to the large sequencing numbers; and each order in the assembly orders is positioned in the same order group with the order corresponding to the sequencing number, and the assembly parameters of each order in the assembly orders are the same.

In the embodiment of the invention, the assembly orders corresponding to the sequencing numbers can be determined sequentially according to the sequence from the sequencing number to the sequencing number. In the assembly order, the order corresponding to the sorting number may be a master order, and the other orders except the master order in the assembly order may be slave orders. All orders in the assembly order are located in the same initial order group as the main order, and the assembly parameters of all orders in the assembly order are the same. Alternatively, the assembly parameters for each of the assembly orders may be the same as the assembly parameters for the master order.

In an embodiment of the present invention, the order of the solar cell module may include: the above assembly parameters. The assembly parameters may include: receiving downshifts, receiving inventory, receiving reflective strips, and the like. The same assembly parameters are the same for each assembly parameter.

For example, there are 8 orders in the initial order group where order number 1 is placed. The order with the sequence number of 1 corresponds to the assembly parameters: receiving downshifts, receiving stock, and receiving reflective strips. If the 8 orders, in addition to the master order with the order number of 1, there are 5 orders respectively: the assembly parameters corresponding to the order B, the order C, the order D, the order E and the order F are also as follows: receiving downshifts, receiving stock, and receiving reflective strips. The remaining 2 orders are respectively: order H, order K. The assembly parameters for order H are: the method does not accept downshifts, accepts stock and accepts reflective stickers, and the assembly parameters of the order K are as follows: receiving downshifts, not receiving stock, not receiving reflective strips. Then, the assembly order corresponding to the order with the order number of 1 is: master order with order number 1, and 5 slave orders of order B, order C, order D, order E, order F.

In the embodiment of the present invention, in the process of determining the order of the order number, if the assembly parameters of the order number include: if any one of the downshift, inventory and light-emitting strip is not accepted, the orders with the ordering numbers are positioned in the same initial order group, and the light-emitting strip is assembled into an assembled order without accepting the downshift, inventory or light-emitting strip.

In an embodiment of the present invention, the number of orders in the assembly order may be greater than or equal to 1. For example, if the assembly parameters of the order corresponding to the order number are: does not accept downshifts, does not accept inventory, and accepts the light stick. The assembly parameters of other orders corresponding to the order number in the same initial order group are as follows: receiving downshifts, receiving inventory, receiving a light-emitting strip. Then, the order corresponding to the order number cannot be assembled with other orders in the initial order group. And the number of the orders in the assembly orders corresponding to the sequencing numbers is 1, and only the orders corresponding to the sequencing numbers are in the assembly orders corresponding to the sequencing numbers.

Step 104, counting the first number of solar cell modules with high-grade power, the second number of solar cell modules with medium-grade power and the third number of solar cell modules with low-grade power in the assembly order respectively.

In the embodiment of the invention, the first quantity, the second quantity and the third quantity respectively required by the solar cell module with high-grade power, the solar cell module with medium-grade power and the solar cell module with low-grade power in each order can be calculated according to the total power of the orders and the power corresponding to the solar cell modules. Typically, high gear power x first sub-amount + medium gear power x second sub-amount + low gear power x third sub-amount = total power.

For example, for the above example, order a for the solar cell assembly may include: the total power is 1.0001MW, the high-grade power is: 375W, mid range power: 370W, low power is: 365W.1MW = 1000000W. Then, in the calculated order a for the solar cell module, the first sub-number required for the solar cell module with high power 375W may be 314, 314×375= 117750W, the second sub-number required for the solar cell module with middle power 370W may be 2100, 2000×370= 740000W, and the third sub-number required for the solar cell module with low power 365W may be 390. 390 x 365 = 142350W. 117750+740000+142350= 1000100 w=1.0001 MW. Then, in order a for solar cell module, the first sub-number of solar cell modules required for high-grade power 375W is 314, the second sub-number of solar cell modules required for medium-grade power 370W is 2000, and the third sub-number of solar cell modules required for low-grade power 360W is 390.

In the embodiment of the invention, the order may also directly include the first sub-number, the second sub-number and the third sub-number required by the solar cell module with high-grade power, the solar cell module with medium-grade power and the solar cell module with low-grade power respectively. Then, in this step, the order is obtained directly. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, according to the first sub-quantity, the second sub-quantity and the third sub-quantity corresponding to each order in the assembly order, the first quantity required by the solar cell module with high-grade power, the second quantity required by the solar cell module with medium-grade power and the third quantity required by the solar cell module with low-grade power are counted respectively.

Specifically, summing the first sub-numbers of the solar cell modules with high-grade power required by each order in the assembly order to obtain the first number required by the solar cell modules with high-grade power of the assembly order. And summing the second sub-quantities of the solar cell modules with the middle-grade power required by each order in the assembly order to obtain the second quantity required by the solar cell modules with the middle-grade power in the assembly order. And summing the third sub-quantities of the solar cell modules with low-grade power required by each order in the assembly order to obtain the third quantity required by the solar cell modules with low-grade power of the assembly order.

And 105, determining a target solar cell corresponding to the assembly order from a plurality of solar cells to be selected according to the first quantity, the second quantity and the third quantity corresponding to the assembly order and the output power distribution proportion of the high, medium and low-grade components corresponding to the solar cell.

In the embodiment of the invention, in the process of producing the solar cell module by using a batch of solar cell sheets, the solar cell module which can generate high-grade power, the solar cell module with middle-grade power and the low-grade solar cell module cannot be avoided. In addition, in the process of producing the solar cell modules by the batch of solar cell sheets, the obtained high-grade power solar cell modules, medium-grade power solar cell modules and low-grade solar cell modules generally show normal distribution. The solar cell modules of the middle-grade power have relatively more duty ratios or numbers, and the solar cell modules of the low-grade power and the solar cell modules of the high-grade power have relatively fewer duty ratios or numbers.

In the process of producing the solar cell modules by a batch of solar cell sheets, the obtained quantity proportion of the solar cell modules with high-grade power, the solar cell modules with medium-grade power and the low-grade solar cell modules is the distribution proportion of the output power of the high-grade, medium-grade and low-grade modules corresponding to the solar cell sheets. The distribution ratio is generally determined by the properties of the battery itself, etc. The distribution ratio can be determined in advance. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, the target solar cell corresponding to the assembly order can be determined from a plurality of solar cells to be assembled according to the first number, the second number and the third number corresponding to the assembly order and the distribution ratio of the output power of the high-grade component, the middle-grade component and the low-grade component corresponding to each solar cell to be assembled.

Specifically, a solar cell primary selection group which is the same as or matched with the grouping parameters of the assembly order can be selected from a plurality of solar cells to be selected. And then, in the solar cell primary selection group, based on the first quantity, the second quantity and the third quantity, and the output power distribution proportion of the high, medium and low grade components corresponding to each type of solar cell to be selected, the solar cell which is matched with the first quantity, the second quantity and the third quantity of the assembly order in proportion is taken as the final target solar cell of the assembly order in various types of solar cell to be selected. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the present invention, it should be noted that, the assembly orders corresponding to the respective sorting numbers are determined sequentially, and the assembly orders are performed after the matched demand of the assembly orders corresponding to the preamble sorting numbers is deducted. Similarly, in determining a target solar cell corresponding to an assembly order from a plurality of solar cells to be selected, it is also necessary to perform the determination on the basis of deducting the already consumed solar cell. That is, the above-described determination of the assembly order corresponding to each sort number is dynamically performed based on the remaining orders after matching. The subsequent selection of the target solar cell is based on the dynamic progress of the remaining solar cells after consumption.

For example, for the previous example, in determining an assembly order for an order with a rank number of 1, there is no rank number before the rank number of 1. Then no subtraction has to be considered. However, in determining the assembly order for the order with the order number of 2, the assembly needs to be performed after the assembly order corresponding to the order with the order number of 1 is deducted and the remaining order cases are matched. In determining the target solar cell for the assembly order corresponding to the order with the order number of 2, the process is also performed after deducting the solar cell consumed by the assembly order corresponding to the order with the order number of 1. In determining the assembly order for the order with the order number of 3, the assembly needs to be performed after the order with the order number of 1 and the order with the order number of 2 are deducted, and the rest of the order cases are performed after the corresponding assembly orders are matched. In the process of determining the target solar cell for the assembly order corresponding to the order with the order number of 3, the order with the order number of 1 and the order with the order number of 2 are subtracted, and the process is also performed after the solar cell consumed by the corresponding assembly order. And so on. In the embodiment of the invention, the assembly orders are determined for each sequencing number in turn according to the sequence from the sequencing number to the large sequencing number, and the target solar cell is determined for each assembly order until all orders are matched with the target solar cell, and the matching process is ended, or the matching process is ended until the plurality of solar cells to be selected are completely consumed.

In the embodiment of the application, compared with the prior art, the matched solar cell sheets are manually selected for each order, and due to different manual experiences and lack of scientific support, the selected solar cell sheets are easy to cause resource waste and increase invalid output. In the application, a plurality of orders are grouped, orders with the same grouping parameters are divided into the same initial order group, orders of a plurality of solar cell modules are ordered according to a preset rule to obtain ordering numbers, assembly orders corresponding to the ordering numbers are sequentially determined according to the order of the ordering numbers from small to large, each order in the assembly orders is positioned in the same initial order group with the order corresponding to the ordering number, and the assembly parameters of each order in the assembly orders are the same; and counting to obtain the first quantity, the second quantity and the third quantity required by the solar cell module with high-grade power, the solar cell module with medium-grade power and the solar cell module with low-grade power in an assembly order, and determining the target solar cell corresponding to the assembly order in various solar cell pieces to be selected according to the first quantity, the second quantity and the third quantity corresponding to the assembly order and the distribution proportion of the output power of the high-grade module, the medium-grade module and the low-grade module corresponding to the solar cell pieces. The standard is unified in the process of determining the target solar cell corresponding to the assembly order, and meanwhile, the quantity respectively required by the high-grade power solar cell component, the medium-grade power solar cell component and the low-grade power solar cell component in the assembly order is directly and fully considered, so that the target solar cell determined for the assembly order is more objective and rational, and resource waste and invalid output can be avoided to a great extent; in addition, in the process of matching the solar cells, the solar cells with low efficiency values can be preferentially consumed according to the sequence from small to large in sequence numbers, byproducts are reduced, and resource waste and invalid output can be avoided to a great extent.

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a solar cell matching method according to an embodiment of the present invention.

Step 201, grouping orders of a plurality of solar cell modules to obtain at least one initial order group; each of the orders in the assembled order has the same grouping parameters; solar module type, bill of materials parameters of the solar module; the power of the solar cell module includes: at least one of high power, medium power, and low power.

Step 202, ordering orders of the solar cell modules according to a preset rule to obtain an ordering number.

In the embodiment of the present invention, the step 201 and the step 202 may refer to the related descriptions of the step 101 and the step 102, respectively, and in order to avoid repetition, the description is omitted here.

Step 203, determining the remaining orders corresponding to the sorting numbers; the remaining orders are: and the orders of the solar cell modules are matched with the residual orders on the basis of the target solar cell pieces in all assembly orders corresponding to all sequencing numbers except the sequencing number.

In the embodiment of the invention, in the process of determining the assembly order for a certain sequencing number, the remaining orders on the basis of the target solar cell pieces are matched in all the assembly orders corresponding to all the sequencing numbers before the sequencing number are deducted from all the orders of all the solar cell assemblies required to be determined.

For example, for the previous example, the order with order number 1 corresponds to the assembly order as: master order with order number 1, and 5 slave orders of order B, order C, order D, order E, order F. Before determining the assembly order corresponding to the order with the order number of 2, subtracting the order or part of the orders which are matched with the target solar cell for the assembly order corresponding to the order with the order number of 1 from all the orders, and obtaining the rest orders corresponding to the order with the order number of 2, or obtaining the rest orders corresponding to the order with the order number of 2.

Step 204, for the remaining orders, determining the assembly orders corresponding to the sorting numbers sequentially according to the order from the small sorting numbers to the large sorting numbers.

And sequentially determining the assembly orders corresponding to all the sequencing numbers according to the sequence from the sequencing number to the large sequence in the rest orders which are matched with the target solar cell in all the assembly orders corresponding to all the sequencing numbers before the sequencing number is deducted.

For example, for the above example, the assembly order corresponding to the order number 2 is determined for the remaining orders corresponding to the order number 2. And determining the assembly order corresponding to the sorting number 3 from the rest orders corresponding to the sorting number 3.

That is, the above-mentioned determination of the assembly orders corresponding to the respective sort numbers is dynamically performed based on the remaining orders after matching, and repeated matching of the already matched orders or partial orders can be avoided.

Step 205, determining the remaining solar cells corresponding to the sorting numbers; the residual solar cell is as follows: and among the plurality of solar cells to be selected, the solar cells to be selected remaining after the target solar cells are matched in all the assembly orders corresponding to all the sequencing numbers before the sequencing numbers are deducted.

In the embodiment of the invention, the remaining solar cells corresponding to the sequencing numbers are determined. The remaining solar cells corresponding to the sequencing numbers are: and buckling the remaining solar cells to be selected after the target solar cells are matched in all assembly orders corresponding to all sequencing numbers before the sequencing number in the plurality of solar cells to be selected. Further, the subsequent scoring or selecting of the target solar cell is dynamically performed based on the remaining solar cells after the consumption.

For example, for the foregoing example, the determination of the remaining solar cells corresponding to the rank number 2 may be specifically: and deducting solar cells remaining after the target solar cells are matched for the assembly order corresponding to the order with the sequence number of 1 from all the plurality of matched solar cells to be selected. The determination of the remaining solar cells corresponding to the ranking number 3 may be specifically: and deducting the solar cells which remain after the target solar cells are matched for the assembly order corresponding to the order with the sequence number of 2 from all the plurality of matched solar cells to be selected.

Step 206, counting the first number of solar cell modules with high-grade power, the second number of solar cell modules with medium-grade power and the third number of solar cell modules with low-grade power in the assembly order respectively.

In the embodiment of the present invention, the step 206 may refer to the related description of the step 103, and in order to avoid repetition, the description is omitted here.

It should be noted that the above-described step 206 and step 205 may be performed simultaneously, or the step 206 may be performed before the step 205, or the like. In the embodiment of the present invention, the execution sequence of step 206 and step 205 is not particularly limited.

Step 207, determining the target solar cell corresponding to the assembly order from the remaining solar cells according to the first number, the second number, the third number, and the output power distribution ratio of the high, medium, and low-grade components corresponding to the solar cell.

In the embodiment of the invention, the first number, the second number and the third number corresponding to the assembly order of the sequencing number can be determined as the target solar cell corresponding to the assembly order of the sequencing number according to the first number, the second number and the third number corresponding to the assembly order of the sequencing number and the distribution proportion of the output power of the high, medium and low grade components corresponding to the solar cell. Namely, the process of selecting the target solar cell is dynamically performed based on the consumed residual solar cell.

In an embodiment of the present invention, optionally, the order further includes: a fourth number of solar cells comprised by the single solar cell assembly; prior to step 207 described above, the method may further comprise the steps of:

and S1, multiplying the surface area and the battery efficiency of the residual solar battery pieces by the fourth quantity to obtain initial power of the component corresponding to the residual solar battery pieces.

And S2, taking the initial power of the component corresponding to the residual solar cell as the middle-grade output power, and obtaining the distribution proportion of the output powers of the high-grade component, the middle-grade component and the low-grade component corresponding to the residual solar cell.

And step S3, obtaining the total power output corresponding to the residual solar cell.

And S4, summing the total power corresponding to each order in the assembly order to obtain the total power corresponding to the assembly order.

In an embodiment of the present invention, the fourth number of solar cells included in a single solar cell module may be 60 or 72, etc. That is, a single solar cell module is composed of a fourth number of solar cells.

In the embodiment of the invention, the efficiency of various residual solar cells can be the power generated per unit surface area under the condition that the residual solar cells work normally in the solar cell module. The efficiency of the remaining solar cell is the self-characteristics of the remaining solar cell, and can be obtained by measurement in advance. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, the product of the efficiency of the remaining solar cell and the surface area of the remaining solar cell may be the power of the remaining solar cell under the condition that the remaining solar cell normally works in the solar cell module. And multiplying the surface area and the cell efficiency of the residual solar cells by the fourth number of the solar cells included in the single solar cell module and the packaging loss to obtain the initial power of the solar cell module corresponding to the residual solar cells.

And taking the initial power of the component corresponding to the residual battery piece as the middle-grade output power. The distribution ratio of the output power of the high, medium and low grade components corresponding to the residual solar cell is usually the self characteristic of the residual solar cell, and can be obtained in advance.

For example, if the initial power of the solar cell module corresponding to the remaining solar cell is 370W, the output powers of the high, medium and low-grade modules corresponding to the remaining solar cell may be respectively: 375W, 370W, 365W.

In the embodiment of the invention, the output of the residual solar cell can be multiplied by the power of the residual solar cell under the condition of normal operation in the solar cell module to obtain the corresponding total output of the power of the residual solar cell.

For example, if the month yield of the remaining solar cells is 10 tens of thousands, and the power of a single remaining solar cell in the case of normal operation in the solar cell module is m, the total power yield corresponding to the remaining solar cell may be: 100000 Xm.

And summing the total power corresponding to each order in one assembly order to obtain the total power corresponding to the assembly order. I.e. the power required in common for all orders in the assembly order.

Optionally, the step 207 may include: and respectively scoring the residual solar cells based on the total power output corresponding to the residual solar cells, the total power corresponding to the assembly order, the first quantity, the second quantity and the third quantity corresponding to the assembly order and the output power distribution proportion of the high, medium and low-grade components corresponding to the residual solar cells, and determining the residual solar cells with the highest scores as the target solar cells corresponding to the assembly order.

In the embodiment of the invention, the degree of matching of the residual solar cell with the assembly order can be reflected by the residual solar cell scoring. And the available solar cell sheets can be roughly selected from the rest solar cell sheets according to grouping parameters corresponding to the assembly order. And then, in the available solar cells, respectively scoring each available solar cell according to the total power output corresponding to each available solar cell, the total power corresponding to the assembly order, the first quantity, the second quantity, the third quantity and the output power distribution proportion of the high-grade component, the middle-grade component and the low-grade component corresponding to each available solar cell, and determining the available solar cell with the highest score as the target solar cell corresponding to the assembly order.

For example, when the distribution ratio of the output power of the high, middle and low-grade components corresponding to the remaining solar cells or the available solar cells is closer to the distribution ratio of the high, middle and low-grade components required by the assembly order, it is described that the distribution ratio of the high, middle and low-grade components is closer to the distribution ratio of the high, middle and low-grade components required by the assembly order in the obtained solar cell module after the remaining or available solar cells are put into production, so that the solar cell module with each grade of power is not much left, the possibility of using the downshift is lower, and resource waste and invalid output can be avoided to a great extent. Therefore, in the case that the distribution ratio of the output power of the high, middle and low-grade components corresponding to the residual or available solar cells is closer to the distribution ratio of the high, middle and low-grade components required by the assembly order, the score corresponding to the factor can be higher.

In the embodiment of the present invention, referring to fig. 3, fig. 3 is a flowchart showing a step of scoring a solar cell according to one embodiment of the present invention. Optionally, the scoring the remaining solar cells based on the total power output corresponding to the remaining solar cells, the total power corresponding to the assembly order, the first number, the second number, the third number corresponding to the assembly order, and the output power distribution ratio of the high, medium, and low-grade components corresponding to the remaining solar cells may include:

And step S111, taking the minimum value in the total power corresponding to the assembly order and the total power yield corresponding to the residual solar cell.

And step S112, multiplying the minimum value by the output power distribution proportion of the high-grade component, the middle-grade component and the low-grade component corresponding to the residual solar cell respectively to obtain the effective output power of the high-grade component, the effective output power of the middle-grade component and the effective output power of the low-grade component corresponding to the residual solar cell.

And step S113, dividing the high-grade component effective output power, the middle-grade component effective output power and the low-grade component effective output power corresponding to the residual solar cell pieces by the high-grade power, the middle-grade power and the low-grade power corresponding to the orders respectively to obtain the high-grade effective output, the middle-grade effective output and the low-grade effective output corresponding to the residual solar cell pieces.

And step S114, taking the minimum value in the first quantity corresponding to the assembly order and the high-grade effective yield corresponding to the residual solar cell to obtain the first matching quantity of the high-grade corresponding to the residual solar cell.

And step S115, taking the minimum value in the second quantity corresponding to the assembly order and the middle-gear effective yield corresponding to the residual solar cell, and obtaining the second matching quantity of the middle gear corresponding to the residual solar cell.

And step S116, taking the minimum value in the third quantity corresponding to the assembly order and the low-gear effective yield corresponding to the residual solar cell to obtain the third matching quantity of the low-gear corresponding to the residual solar cell.

And step S117, determining the corresponding scoring of the residual solar cell pieces based on the sum of the first matching amount, the second matching amount and the third matching amount.

Specifically, the minimum value may be taken from the total power corresponding to the assembly order and the total power yield corresponding to the remaining solar cells. That is, if the total power output corresponding to the remaining solar cells is greater than the total power corresponding to the assembly order, if the total power of the solar cell module obtained after the remaining solar cells are all put into production exceeds the total power required by the assembly order, wasteful or ineffective output may occur. If the total power corresponding to the assembly order is larger than the total power output corresponding to the residual solar cell, the total power of the solar cell assembly obtained after the residual solar cell is fully put into production is not enough to meet the total power required by the assembly order, and basically no waste or invalid output is generated. Therefore, only the minimum value is selected from the two values, so that the waste or invalid output is basically avoided. This minimum value may be initially considered as the total power of the solar module that may be produced after a subsequent production of the planned customization.

And multiplying the minimum value obtained in the total power corresponding to the assembly order and the total power output corresponding to the residual solar cell by the output power distribution proportion of the high-grade component, the middle-grade component and the low-grade component corresponding to the residual solar cell respectively to obtain the effective output power of the high-grade component, the effective output power of the middle-grade component and the effective output power of the low-grade component corresponding to the residual solar cell. That is, the total power of the remaining solar cell modules which are planned and put into operation is multiplied by the distribution ratio of the output powers of the high-grade module, the middle-grade module and the low-grade module which can be obtained in the production process of the remaining solar cell modules, so that the effective output powers of the high-grade module, the middle-grade module and the low-grade module which can be obtained after planned and put into operation are obtained.

And dividing the effective output power of the high-grade component, the effective output power of the middle-grade component and the effective output power of the low-grade component corresponding to the residual solar cell pieces by the high-grade power, the middle-grade power and the low-grade power corresponding to the orders respectively to obtain the high-grade effective output, the middle-grade effective output and the low-grade effective output corresponding to the residual solar cell pieces. That is, the solar cell module of how many high-grade powers are possible to obtain after the planned customized casting can be obtained by dividing the available power of all high-grade modules possible to obtain after the planned customized casting by the high-grade power of the solar cell module of the single high-grade power in the assembly order. And dividing the available power output of all the intermediate-grade components possibly obtained after the planned and customized casting by the intermediate-grade power of the solar cell module with single intermediate-grade power in the assembly order, namely obtaining the solar cell module with the planned and customized power output possibly obtained after the planned and customized casting. The low-grade power of the solar cell modules with single low-grade power in the assembly order is divided by the effective power of all low-grade modules possibly obtained after the planned and customized casting, namely, the number of the solar cell modules with the low-grade power possibly obtained after the planned and customized casting can be obtained.

If the high-end effective yield of the high-end power solar module for which custom production is planned is greater than the first number of high-end power solar modules required for the assembly order, wasteful or ineffective production may occur. If the high-end effective yield of the high-end power solar module for which customized production is planned is less than or equal to the first number of high-end power solar modules required for the assembly order, substantially no wasteful or ineffective production will occur. Therefore, the first matching amount of the solar cell module with the high-grade power of the assembly order and the residual solar cell after planned casting is obtained by taking the minimum value of the first quantity corresponding to the assembly order and the high-grade effective yield corresponding to the residual solar cell. That is, after the planned production, the batch production meets the actual number of solar cell modules of high-grade power in the assembly order: a first matching amount. And so on, obtaining the actual number of solar cell modules in the batch that meet the mid-range power in the assembly order: a second matching amount. The actual number of solar cell modules that meet the low power in the assembly order: a third matching amount.

If such a surplus solar cell is put into production, if a first matching amount of high-power solar cell modules is just obtained, it is indicated that the high-power solar cell modules obtained by production are just equal to the first number of high-power solar cell modules required by the assembly order, or are smaller than the first number of high-power solar cell modules required by the assembly order, then no resource waste or no invalid production is substantially generated. And so on, if the remaining solar cells are put into production, if the solar cell modules with the second matching amount of the middle-grade power are just obtained, the solar cell modules with the middle-grade power obtained by production are just equal to the first number of the solar cell modules with the middle-grade power required by the assembly order, or the second number of the solar cell modules with the middle-grade power required by the assembly order is smaller than the first number of the solar cell modules with the middle-grade power required by the assembly order, the waste of resources is basically avoided or the invalid output is basically avoided. If the remaining solar cells are put into production, if the third matching amount of low-power solar cell modules is just obtained, the low-power solar cell modules obtained by production are just equal to the first number of low-power solar cell modules required by the assembly order, or are smaller than the first number of low-power solar cell modules required by the assembly order, so that resource waste is basically not generated or invalid production is basically not generated.

And subtracting the byproduct parameters corresponding to the residual solar cell by using the sum of the first matching amount, the second matching amount and the third matching amount to obtain the scoring corresponding to the residual solar cell. Alternatively, the by-product parameters corresponding to the remaining solar cells may be subtracted from the sum of the first matching amount, the second matching amount, and the third matching amount, and the downshift scores corresponding to the remaining solar cells may be subtracted from the sum of the by-product parameters corresponding to the remaining solar cells, to obtain the scores corresponding to the remaining solar cells. The byproduct parameters corresponding to the remaining solar cells may be: the number of solar cell modules produced is increased relative to the solar cell modules required for the assembly order. The byproduct parameters corresponding to the remaining solar cells may include: and the high-grade power byproduct parameters corresponding to the residual solar cells and/or the low-grade power byproduct parameters corresponding to the residual solar cells. The downshift score corresponding to the remaining solar cells may be characterized: the solar cell module with high-grade power generated by the residual solar cell is used as a solar cell module with medium-grade power, so that resources are wasted or invalid to be generated.

By considering the first matching amount of the high-grade effective yield corresponding to the battery piece and the high-grade power solar cell module corresponding to the assembly order, the second matching amount of the medium-grade effective yield corresponding to the battery piece and the medium-grade power solar cell module corresponding to the assembly order, the third matching amount of the low-grade effective yield corresponding to the battery piece and the low-grade power solar cell module corresponding to the assembly order, scoring is carried out from the high-grade power solar cell module corresponding to the assembly order, the medium-grade power solar cell module and the low-grade power solar cell module respectively, the scoring is more detailed and comprehensive, and then the solar cell with the highest scoring is selected from a plurality of residual solar cells as the target solar cell of the order, so that invalid output or resource waste can be reduced as far as possible.

In an embodiment of the present invention, the order may further include: an assembly parameter, which may include a non-downshift or a downshift. A non-downshift may be such that the high power solar cell module in the assembly order cannot be used as a medium power solar cell module and the medium power solar cell module in the assembly order cannot be used as a low power solar cell module. The downshift may be: the solar cell module of the high-grade power in the assembly order can be used as the solar cell module of the medium-grade power, and the solar cell module of the medium-grade power in the assembly order can be used as the solar cell module of the low-grade power.

Referring to fig. 4, fig. 4 is a flowchart showing a step of determining remaining solar cell scores in the case where the downshift parameter of the assembly order is non-downshift in accordance with an embodiment of the present invention. Alternatively, in the case where the downshift parameter of the assembly order is a non-downshift, step S117 described above may include:

and step S1171, subtracting the first quantity corresponding to the assembly order from the high-grade effective yield corresponding to the residual solar cells to obtain high-grade power byproduct parameters corresponding to the residual solar cells.

And step S1172, subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar cells to obtain the low-grade power byproduct parameters corresponding to the residual solar cells.

And step S1173, subtracting the sum of the high-grade power byproduct parameter corresponding to the residual solar cell and the low-grade power byproduct parameter corresponding to the residual solar cell from the sum of the first matching amount, the second matching amount and the third matching amount corresponding to the residual solar cell to obtain the score corresponding to the residual solar cell.

Specifically, the order includes a case where a downshift parameter of a certain assembly order is a non-downshift, that is, a case where a solar cell module of a high-grade power in the assembly order cannot be used as a solar cell module of a medium-grade power, and the like. Subtracting the first quantity corresponding to the assembly order from the high-grade effective yield corresponding to the residual solar cell to obtain the high-grade power byproduct parameter corresponding to the residual solar cell, namely the quantity of the solar cell components with high-grade power which can be produced more, or the ineffective yield of the solar cell components with high-grade power. And subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar cell to obtain the low-grade power byproduct parameter corresponding to the residual solar cell, namely the quantity of the low-grade power solar cell components which can be produced more, or the ineffective yield of the low-grade power solar cell components.

The greater the first match, the more closely the number of high-power solar modules produced by the remaining solar cells, with the assurance that there is substantially no high-power by-product, is the first number of high-power solar modules required by the assembly order. And so on, the larger the second matching amount, the more closely the number of solar modules of the mid-range power produced by the remaining solar cells is guaranteed to be substantially free of mid-range power byproducts, and the second number of solar modules of the mid-range power is required by the assembly order. The greater the third match, the more closely the number of low power solar modules produced by the remaining solar cells, with the assurance that there is substantially no low power by-product, is the third number of low power solar modules required by the assembly order. Therefore, the sum of the high-grade power byproduct parameter corresponding to the residual solar cell and the low-grade power byproduct parameter corresponding to the residual solar cell can be subtracted from the sum of the first matching amount, the second matching amount and the third matching amount corresponding to the residual solar cell to obtain the score corresponding to the solar cell.

In an embodiment of the present invention, the order may further include: an assembly parameter, which may include a non-downshift or a downshift. The non-downshift and downshift are referred to in the foregoing description and are not repeated here. Referring to fig. 5, fig. 5 is a flowchart showing a step of determining solar cell scoring in the case where a downshift parameter of an assembly order is a downshift in an embodiment of the present invention. Alternatively, in the case where the downshift parameter of the assembly order is a non-downshift, step S117 described above may include:

and step S1174, subtracting the first quantity corresponding to the assembly order from the high-grade effective yield corresponding to the residual solar cells to obtain the downshift quantity corresponding to the residual solar cells.

And step S1175, subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar cells to obtain the low-grade power byproduct parameters corresponding to the residual solar cells.

And step S1176, subtracting the low-grade power byproduct parameter corresponding to the residual solar cell by using the sum of the first matching amount, the second matching amount and the third matching amount corresponding to the residual solar cell, and subtracting the downshift score corresponding to the downshift number to obtain the scoring corresponding to the residual solar cell.

In the embodiment of the present invention, in the case where the downshift parameter of a certain assembly order is downshift, that is, the solar cell module with high-grade power in the assembly order may be used as the solar cell module with medium-grade power, or the like. Then, subtracting the first number corresponding to the assembly order from the high-grade effective yield corresponding to the remaining solar cells, to obtain the number of downshifts corresponding to the remaining solar cells, that is, the number of solar cell modules with high-grade power that may be produced more, and the number of solar cell modules that need to be used as intermediate-grade power. Although this part is not wasted completely, the use of the solar cell module with high power as the solar cell module with medium power causes a waste of some resources and also has an ineffective output. The solar cell module with high-grade power in the assembly order can be used as the solar cell module with medium-grade power, and the parameter of the byproduct with high-grade power corresponding to the solar cell sheet can be considered to be 0, that is, the solar cell module with high-grade power obtained by producing the residual solar cell sheet is used up. By considering the downshift score, the control of the resource waste or the invalid output is finer, which is beneficial to further reducing the resource waste or the invalid output.

And subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar cell to obtain the low-grade power byproduct parameter corresponding to the residual solar cell, namely the quantity of the solar cell components with low-grade power which can be produced more, or the ineffective yield of the solar cell components with low-grade power.

The greater the first match, the more closely the number of high-power solar modules produced by the remaining solar cells, with the assurance that there is substantially no high-power by-product, is the first number of high-power solar modules required by the assembly order. And so on, the larger the second matching amount, the more closely the number of solar modules of the mid-range power produced by the remaining solar cells is guaranteed to be substantially free of mid-range power byproducts, and the second number of solar modules of the mid-range power is required by the assembly order. The greater the third match, the more closely the number of low power solar modules produced by the remaining solar cells, with the assurance that there is substantially no low power by-product, is the third number of low power solar modules required by the assembly order. Therefore, the sum of the first matching amount, the second matching amount and the third matching amount corresponding to the residual solar cell can be used for subtracting the low-grade power byproduct parameter corresponding to the residual solar cell, and then subtracting the downshift fraction corresponding to the downshift number to obtain the fraction corresponding to the residual solar cell.

And finally, selecting the solar cell with the highest grading from a plurality of residual solar cells as the target solar cell corresponding to the assembly order, and further, selecting the target solar cell with smaller degree of resource waste or invalid output.

In an embodiment of the present invention, optionally, before the step S1176, the method may further include: and multiplying the downshift number by a preset downshift coefficient to obtain the downshift fraction. The downshift coefficient may be indicative of a possible waste of resources or an ineffective output in the case where a high power solar module is used as a medium power solar module. And multiplying the total downshift number by a preset downshift coefficient to obtain the downshift fraction, wherein the downshift fraction can reflect the resource waste or invalid output caused by all downshifts. The preset downshift coefficient may be set according to actual needs, or the like. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the application, the degree of matching of the residual solar cell with the assembly order can be reflected by the residual solar cell scoring. Therefore, among a plurality of scores corresponding to a plurality of residual solar cell pieces, the residual solar cell piece with the highest score can be determined as the target solar cell piece corresponding to the assembly order, which is beneficial to further reducing resource waste or invalid output.

In the embodiment of the application, compared with the prior art, the matched solar cell sheets are manually selected for each order, and due to different manual experiences and lack of scientific support, the selected solar cell sheets are easy to cause resource waste and increase invalid output. In the application, a plurality of orders are grouped, orders with the same grouping parameters are divided into the same initial order group, and orders of a plurality of solar cell modules are ordered according to a preset rule to obtain ordering numbers; sequentially determining the assembly orders corresponding to the sequencing numbers according to the sequence from the small sequencing number to the large sequencing number; each order in the same assembly order is located in the same initial order group with the order corresponding to the ordering number, and the assembly parameters of each order in the assembly order are the same; and counting to obtain the first quantity, the second quantity and the third quantity required by the solar cell module with high-grade power, the solar cell module with medium-grade power and the solar cell module with low-grade power in an assembly order, and determining the solar cell with highest scoring among various solar cells to be selected as a target solar cell corresponding to the assembly order according to the first quantity, the second quantity and the third quantity corresponding to the assembly order and the distribution proportion of the output power of the high, medium and low-grade modules corresponding to the solar cell. The standard is unified in the process of determining the target solar cell corresponding to the assembly order, and meanwhile, the quantity respectively required by the high-grade power solar cell component, the medium-grade power solar cell component and the low-grade power solar cell component in the assembly order is directly and fully considered, so that the target solar cell determined for the assembly order is more objective and rational, and resource waste and invalid output can be avoided to a great extent; in addition, in the process of matching the solar cells, the solar cells with low efficiency values can be preferentially consumed according to the sequence from small to large in sequence numbers, byproducts are reduced, and resource waste and invalid output can be avoided to a great extent.
