For example, if the assembly parameters of the order corresponding to the sequence number are: no downshift, no inventory, and receiving a stick-on light. And the assembly parameters of other orders of which the orders corresponding to the sequence numbers are positioned in the same initial order group are as follows: accept downshifts, accept stock, accept placement of light strips. Then, the order corresponding to the sequence number and other orders in the initial order set cannot be assembled. Then, the number of orders in the assembly orders corresponding to the sequence number is 1, and only the order corresponding to the sequence number is in the assembly orders corresponding to the sequence number.

And 104, respectively counting a first quantity required by the solar battery assemblies with high-grade power, a second quantity required by the solar battery assemblies with medium-grade power and a third quantity required by the solar battery assemblies with low-grade power in the assembly order.

In the embodiment of the invention, the first quantity, the second quantity and the third quantity respectively needed by the solar cell modules with high-grade power, the solar cell modules with middle-grade power and the solar cell modules 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. In general, the high range power × the first subset + the medium range power × the second subset + the low range power × the third subset equals the total power.

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

In the embodiment of the present invention, the order may also directly include the first sub-quantity, the second sub-quantity, and the third sub-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. Then, in this step, it is sufficient to directly obtain the order. 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 battery assembly with high-grade power, the second quantity required by the solar battery assembly with medium-grade power and the third quantity required by the solar battery assembly with low-grade power of the order group are respectively counted.

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

And 105, determining a target solar cell corresponding to the assembly order from among the multiple 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 ratios of the high-grade assembly, the medium-grade assembly and the low-grade assembly corresponding to the solar cells.

In the embodiment of the invention, during the process of producing the solar cell module by using a batch of solar cells, the solar cell module with high-grade power, the solar cell module with medium-grade power and the low-grade solar cell module can not be generated. Moreover, in the process of producing the solar cell module by the batch of solar cells, the obtained high-grade power solar cell module, medium-grade power solar cell module and low-grade solar cell module usually show normal distribution. The proportion or the number of the solar cell modules with the medium-grade power is relatively large, and the number of the solar cell modules with the low-grade power and the number of the solar cell modules with the high-grade power are relatively small.

In the process of producing solar cell modules by a batch of solar cells, the number ratio of the obtained high-grade power solar cell modules, the obtained medium-grade power solar cell modules and the obtained low-grade power solar cell modules is the distribution ratio of the output power of the high-grade module, the output power of the medium-grade module and the output power of the low-grade module corresponding to the solar cells. The distribution ratio is generally determined by the properties of the battery itself, and the like. 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 present invention, according to the first quantity, the second quantity, and the third quantity corresponding to the assembly order, and the output power distribution ratio of the high-grade module, the medium-grade module, and the low-grade module corresponding to each solar cell to be selected, a target solar cell corresponding to the assembly order is determined among the plurality of solar cells to be selected.

Specifically, a solar cell primary selection group which is the same as or matched with the grouping parameters of the assembly order may be selected from a plurality of solar cells to be selected. And then in the initial group of the solar cells, based on the first quantity, the second quantity and the third quantity and the output power distribution proportion of the high-grade component, the medium-grade component and the low-grade component corresponding to each solar cell to be selected, taking the solar cells matched with the first quantity, the second quantity and the third quantity proportion of the assembly order as final target solar cells of the assembly order in various solar cells 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 sequence numbers are sequentially determined, and the assembly orders corresponding to the preamble sequence numbers need to be deducted from the matched required quantity. Similarly, in the multiple candidate solar cells, the target solar cell corresponding to the assembly order is determined on the basis of deducting the consumed solar cell. That is, the above-mentioned determination of the assembly order corresponding to each sort number is performed dynamically based on the remaining orders after matching. And the subsequent process of selecting the target solar cell is dynamically carried out based on the residual solar cells after consumption.

For example, for the foregoing example, in determining an assembly order for an order with a sequence number of 1, there is no sequence number before the sequence number of 1. Then no deduction needs to be considered. However, in the process of determining the assembly order for the order with the sequence number 2, the assembly needs to be performed after the assembly order corresponding to the order with the sequence number 1 is deducted and is matched. In the process of determining the target solar cell for the assembly order corresponding to the order with the sequence number 2, the solar cell consumed by the assembly order corresponding to the order with the sequence number 1 is also deducted. In the process of determining the assembly order for the order with the sequence number of 3, the order with the sequence number of 1 is deducted, the order with the sequence number of 2 is deducted, and the corresponding assembly order is matched, and then the rest of order conditions are carried out for assembly. In the process of determining the target solar cell for the assembly order corresponding to the order with the sequence number of 3, the order with the sequence number of 1 and the order with the sequence number of 2 are also deducted, and the process is performed after the solar cell consumed by the corresponding assembly order is obtained. And so on. In the embodiment of the invention, according to the sequence of the sequence numbers from small to large, the assembly orders are determined for each sequence number in sequence, the target solar cell is determined for each assembly order until all the orders are matched with the target solar cell, and the matching process is finished, or the matching process is finished until the various solar cells to be selected are completely consumed.

In the embodiment of the invention, compared with the prior art that matched solar cells are manually selected for each order, due to different manual experiences and lack of scientific support, the selected solar cells are easy to cause resource waste and increase ineffective output. According to the method, a plurality of orders are grouped, the orders with the same grouping parameters are divided into the same initial order group, the orders of a plurality of solar cell modules are sequenced according to a preset rule to obtain sequencing numbers, the assembly orders corresponding to the sequencing numbers are sequentially determined according to the sequence of the sequencing numbers from small to large, each order in the assembly orders and the order corresponding to the sequencing numbers are located in the same initial order group, and the assembly parameters of each order in the assembly orders are the same; and in one assembly order, calculating a first quantity, a second quantity and a 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, and determining a target solar cell corresponding to the assembly order from the solar cells to be selected according to the first quantity, the second quantity and the third quantity corresponding to the assembly order, and the distribution ratios of the output power of the high-grade, medium-grade and low-grade modules corresponding to the solar cells. The method comprises the steps that the standards are unified in the process of determining target solar cells corresponding to an assembly order, the quantity required by each of solar cell assemblies with middle-high power, solar cell assemblies with middle-high power and solar cell assemblies with low-high power in the assembly order is directly and fully considered, the target solar cells determined for the assembly order are more objective and reasonable, and resource waste and invalid output can be avoided to a great extent; moreover, in the process of matching the solar cells, the solar cells with low consumption efficiency values can be preferentially consumed by performing the sequence from small to large according to the sequence numbers, by-products 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 assembly orders has the same grouping parameters; the type of the solar cell module and the bill of material parameters of the solar cell module; the power of the solar cell module comprises: at least one of high range power, medium range power, and low range power.

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

In the embodiment of the present invention, the

steps

201 and 202 may refer to the related descriptions of the steps 101 and 102, respectively, and are not described herein again to avoid repetition.

Step 203, determining the remaining orders corresponding to the sorting numbers; the remaining orders are: and the orders of the plurality of solar cell assemblies are the remaining orders on the basis that the target solar cell pieces are matched in all assembly orders corresponding to all the sorting numbers before the sorting numbers are deducted.

In the embodiment of the invention, in the process of determining the assembly order for a certain sequence number, the remaining orders, which are obtained by deducting all the assembly orders corresponding to all the sequence numbers before the sequence number from all the orders of all the solar cell modules and are matched with the target solar cell, need to be determined.

For example, for the foregoing example, the assembly order corresponding to the order with the sequence number 1 is: the main order with the sequence number of 1 and 5 auxiliary orders of the order B, the order C, the order D, the order E and the order F. Before determining the assembly order corresponding to the order with the sequence number 2, deducting the assembly order corresponding to the order with the sequence number 1 from all orders to obtain the remaining orders with the sequence number 2 after matching the order or part of the order of the target solar cell, or obtaining the remaining orders corresponding to the order with the sequence number 2.

And 204, sequentially determining the assembly orders corresponding to the sequencing numbers according to the sequence of the sequencing numbers from small to large aiming at the residual orders.

And in the remaining orders on the basis that the target solar cell is matched in all the assembly orders corresponding to all the sorting numbers before the sorting numbers are deducted, sequentially determining the assembly orders corresponding to all the sorting numbers according to the sequence from small to large of the sorting numbers.

For example, in the above example, the assembly order having the sort number 2 is determined for the remaining orders having the sort number 2. And determining the assembly order with the sequence number of 3 in the rest orders with the sequence number of 3.

That is, the above-mentioned determination of the assembly orders corresponding to the respective sequence numbers is performed dynamically based on the remaining matched orders, so that the matched orders or partial orders can be prevented from being repeatedly matched.

Step 205, determining the remaining solar cells corresponding to the sequencing number; the residual solar cells are as follows: and in all the assembly orders corresponding to all the sorting numbers before deducting the sorting numbers, the solar cells to be selected are left after the matched target solar cells in the multiple solar cells to be selected.

In the embodiment of the invention, the remaining solar cells corresponding to the sorting numbers are determined. The remaining solar cells corresponding to the sorting number are: in the multiple solar cells to be selected, in all the assembly orders corresponding to all the sorting numbers before deducting the sorting number, the solar cells to be selected are left after the matched target solar cell. Furthermore, the process of subsequently scoring or selecting the target solar cell is dynamically performed based on the residual solar cells after consumption.

For example, for the foregoing example, the specific step of determining the remaining solar cells corresponding to the sorting number 2 may be: and deducting the solar battery pieces left after the target solar battery piece is matched for the assembly order corresponding to the order with the sequencing number of 1 from all the various solar battery pieces to be selected which can be matched. The specific method for determining the remaining solar cells with the sequencing number of 3 may be: and deducting the solar cell pieces which are left after the assembly order corresponding to the order with the sequencing number of 2 matches the target solar cell piece from all the various solar cell pieces to be selected which can be matched.

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

In the embodiment of the present invention, the step 206 may refer to the related description of the step 103, and is not described herein again to avoid repetition.

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

And step 207, determining a target solar cell corresponding to the assembly order from the rest solar cells according to the first quantity, the second quantity and the third quantity corresponding to the assembly order and the output power distribution ratios of the high-grade, medium-grade and low-grade components corresponding to the solar cells.

In the embodiment of the present invention, according to the first quantity, the second quantity, and the third quantity corresponding to the assembly order of the serial number, and the output power distribution ratio of the high-grade module, the medium-grade module, and the low-grade module corresponding to the solar cell, among the remaining solar cells corresponding to the serial number, the solar cell matched with the first quantity, the second quantity, and the third quantity corresponding to the assembly order of the serial number is determined as the target solar cell corresponding to the assembly order of the serial number. Namely, the process of selecting the target solar cell is dynamically performed based on the residual solar cells after consumption.

In this embodiment of the present invention, optionally, the order further includes: a fourth number of solar cells included in a single solar cell module; before step 207, the method may further include the steps of:

and step S1, multiplying the fourth number by the surface area and the cell efficiency of the residual solar cells to obtain the initial power of the module corresponding to the residual solar cells.

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

And step S3, acquiring the total power output corresponding to the residual solar cells.

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

In the embodiment of the present invention, the fourth number of the solar cell pieces included in the 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 cell pieces.

In the embodiment of the invention, the efficiency of each residual solar cell piece can be the generated power per unit surface area under the condition that the residual solar cell piece normally works in the solar cell module. The efficiency of the remaining solar cell is the self-characteristic 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 present 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 in the case of normal operation in the solar cell module. And multiplying the fourth number of the solar cells included in the single solar cell module by the surface area and the cell efficiency of the remaining solar cells and the packaging loss to obtain the initial power of the solar cell module corresponding to the remaining solar cells.

And taking the initial power of the components corresponding to the rest of the battery pieces as the middle-grade output power. The distribution ratios of the output power of the high-grade, medium-grade and low-grade components corresponding to the residual solar cells are usually the characteristics of the residual solar cells and can be obtained in advance.

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

In the embodiment of the invention, the total power output corresponding to the remaining solar cell can be obtained by multiplying the output of the remaining solar cell by the power of the remaining solar cell in the case of normal operation in the solar cell module.

For example, if the monthly yield of the remaining solar cells is 10 ten thousand, 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 cells 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. That is, all of the assembly orders share the power required.

Optionally, 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-grade assembly, the medium-grade assembly and the low-grade assembly corresponding to the residual solar cells, and determining the residual solar cells with the highest score as the target solar cells corresponding to the assembly order.

In the embodiment of the invention, the scoring of the residual solar cells can reflect the matching degree of the residual solar cells and the assembly order. And roughly selecting available solar cells from the rest solar cells according to the grouping parameters corresponding to the assembly order. And then in the available solar cells, 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 and the third quantity corresponding to the assembly order, and the output power distribution proportion of the high-grade, medium-grade and low-grade components corresponding to each available solar cell, respectively scoring each available solar cell, and determining the available solar cell with the highest score as a target solar cell corresponding to the assembly order.

For example, when the distribution ratios of the output power of the remaining or available solar cells and the distribution ratios of the high, medium and low-grade components required by the assembly order are closer to each other, it is described that after the remaining or available solar cells are put into production, the distribution ratios of the high, medium and low-grade components in the obtained solar cell module are closer to the distribution ratios of the high, medium and low-grade components required by the assembly order, and further, the solar cell modules with each grade of power are not only not much left, but also have lower possibility of being used in downshifting, and further, resource waste and ineffective output can be avoided to a great extent. Therefore, if the distribution ratio of the output power of the high-grade, medium-grade and low-grade components corresponding to the residual or available solar cell is closer to the distribution ratio of the high-grade, medium-grade and low-grade components required by the assembly order, the score corresponding to the factor can be higher.

In the embodiment of the invention, referring to fig. 3, fig. 3 is a flowchart illustrating a step of scoring a solar cell in the embodiment of the invention. Optionally, the scoring the remaining solar cells respectively based on the total power output corresponding to the remaining solar cells, the total power corresponding to the assembly order, the first quantity, the second quantity, the third quantity corresponding to the assembly order, and the distribution ratios of the output power of the high-grade, medium-grade, and low-grade modules corresponding to the remaining solar cells may include:

and step S111, taking the minimum value from the total power corresponding to the assembly order and the total power output corresponding to the residual solar cells.

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

Step S114, taking the minimum value from the first quantity corresponding to the assembly order and the high-grade effective yield corresponding to the remaining solar cells, to obtain a first matching quantity of the high-grade corresponding to the remaining solar cells.

And step S115, taking the minimum value from the second quantity corresponding to the assembly order and the middle gear effective yield corresponding to the residual solar cells to obtain a second matching quantity of the middle gear corresponding to the residual solar cells.

And step S116, taking the minimum value from the third quantity corresponding to the assembly order and the low-grade effective yield corresponding to the residual solar battery pieces to obtain the third matching quantity of the low grade corresponding to the residual solar battery pieces.

And step S117, determining the corresponding score of the residual solar cells 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 output 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, the total power of the solar cell module obtained after the remaining solar cells are all put into production may exceed the total power required by the assembly order, and waste or invalid output may occur. If the total power corresponding to the assembly order is greater than the total power output corresponding to the remaining solar battery pieces, the total power of the solar battery assembly obtained after the remaining solar battery pieces are all put into production is not greater than the total power required by the assembly order, and waste or ineffective output is basically avoided. Therefore, only the minimum value of the two values is selected to preliminarily ensure that waste or invalid output is not generated basically. This minimum value can be initially considered as the total power of the solar module that is likely to be produced after a planned and customized subsequent commissioning.

And respectively multiplying the minimum value of the total power corresponding to the assembly order and the total power output corresponding to the residual solar cell by the distribution proportion of the output power of the high-grade, medium-grade and low-grade components corresponding to the residual solar cell to obtain the effective output power of the high-grade component, the effective output power of the medium-grade component and the effective output power of the low-grade component corresponding to the residual solar cell. That is to say, the total power of the residual solar cell modules which are input by planning is multiplied by the distribution proportion of the output power of the high-grade module, the medium-grade module and the low-grade module which can be obtained in the production process of the residual solar cell modules, and then the effective output power of the high-grade module, the effective output power of the medium-grade module and the effective output power of the low-grade module which can be obtained after the planned customized production are obtained.

And dividing the high-grade power, the medium-grade power and the low-grade power corresponding to the order by the high-grade power, the medium-grade power and the low-grade power corresponding to the residual solar cells respectively to obtain the high-grade effective yield, the medium-grade effective yield and the low-grade effective yield corresponding to the residual solar cells. That is, the effective output power of all high-grade modules which can be obtained after the planned customized production is divided by the high-grade power of the solar cell module with single high-grade power in the assembly order, so that the solar cell module with how many high-grade powers can be obtained after the planned customized production can be obtained. And dividing the effective output power of all the middle-grade components which can be obtained after the planned customized production by the middle-grade power of the solar battery components with single middle-grade power in the assembly order, so as to obtain the number of the solar battery components with the middle-grade power which can be obtained after the planned customized production. And dividing the effective output power of all low-grade components which can be obtained after the planned customized production by the low-grade power of the solar battery components with single low-grade power in the assembly order, so as to obtain the number of the solar battery components with the low-grade power which can be obtained after the planned customized production.

If the high-end, efficient production of high-end power solar modules planned for custom-made production is greater than the first number of high-end power solar modules required to assemble the order, wasteful or inefficient production may occur. If the high-end, effective production of high-end power solar modules planned for custom-commissioning is less than or equal to the first quantity of high-end power solar modules required to assemble the order, substantially no wasted or inefficient production occurs. Therefore, the minimum value is taken from the first quantity corresponding to the assembly order and the high-grade effective yield corresponding to the residual solar cells, and the first matching quantity of the residual solar cells and the high-grade solar cell module with the high-grade power of the assembly order after the planned delivery is obtained. That is, after the planned delivery, the batch produces an actual number of solar modules that meet the high-end power in the assembly order: a first matching amount. And so on, obtaining the actual number of the solar cell assemblies which meet the middle-grade power in the assembly order in the batch production: a second amount of matching. The batch produces an actual number of solar modules that meet the low grade power in the assembly order: and a third amount of matching.

If the solar cell modules with the high-grade power of the first matching amount are just obtained after the rest of the solar cell pieces are put into production, it is indicated that the solar cell modules with the high-grade power obtained by production are just equal to the first number of the solar cell modules with the high-grade power required by the assembly order, or the first number of the solar cell modules with the high-grade power is smaller than the first number of the solar cell modules with the high-grade power required by the assembly order, resource waste is basically not generated or ineffective output is basically not generated. By analogy, if the solar cell modules with the middle-grade power of the second matching amount are obtained right after the rest of the solar cell pieces are put into production, it is indicated that the solar cell modules with the middle-grade power obtained by production are right 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 smaller than the assembly order is obtained, and therefore resource waste is not generated basically or invalid output is not generated basically. If the solar cell modules with the low-grade power of the third matching amount are just obtained after the rest of the solar cell pieces are put into production, it is indicated that the solar cell modules with the low-grade power obtained by the production are just equal to the first number of the solar cell modules with the low-grade power required by the assembly order, or the first number of the solar cell modules with the low-grade power is smaller than the first number of the solar cell modules with the low-grade power required by the assembly order, and therefore resource waste is basically not generated or invalid output is basically not generated.

And subtracting the 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 to obtain the score corresponding to the residual solar cell. Or subtracting the byproduct parameter corresponding to the remaining solar cells and subtracting the downshift fraction corresponding to the remaining solar cells by using the sum of the first matching amount, the second matching amount and the third matching amount to obtain the score corresponding to the remaining solar cells. The byproduct parameters corresponding to the remaining solar cells may be: and increasing the number of produced solar cell modules relative to the solar cell modules required by 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 fraction corresponding to the remaining solar cells may be characterized by: the high-grade power solar cell module produced by the surplus solar cell pieces wastes resources or produces useless power due to the solar cell module used as the medium-grade power solar cell module.

The method comprises the steps of respectively grading the high-grade power solar cell assembly, the medium-grade power solar cell assembly and the low-grade power solar cell assembly corresponding to the assembly order according to a first matching amount of the high-grade effective yield corresponding to the cell slice and the high-grade power solar cell assembly corresponding to the assembly order, a second matching amount of the medium-grade effective yield corresponding to the cell slice and the medium-grade power solar cell assembly corresponding to the assembly order, and a third matching amount of the low-grade effective yield corresponding to the cell slice and the low-grade power solar cell assembly corresponding to the assembly order, wherein the grading is more careful and comprehensive, and the highest-graded solar cell slice is selected from the plurality of residual solar cells to serve as a target solar cell slice of the order, so that the invalid output or resource waste can be reduced as much as possible.

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

Referring to fig. 4, fig. 4 is a flowchart illustrating steps of determining a score of remaining solar cells in a case that a downshift parameter of an assembly order is a non-downshift according to an embodiment of the present invention. Optionally, in the case that the downshift parameter of the assembly order is a non-downshift, the step S117 may include:

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

And 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 a score corresponding to the residual solar cell.

Specifically, the order includes, for example, when the downshift parameter of a certain assembly order is a non-downshift parameter, that is, when the solar cell module of the high-range power in the assembly order cannot be used as the solar cell module of the medium-range power. And subtracting the first quantity corresponding to the assembly order from the high-grade effective yield corresponding to the residual solar cells to obtain the high-grade power byproduct parameter corresponding to the residual solar cells, namely the quantity of the high-grade power solar cell assemblies possibly produced more or the ineffective yield of the high-grade power solar cell assemblies. And subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar cells to obtain a low-grade power byproduct parameter corresponding to the residual solar cells, namely the quantity of the low-grade power solar cell assemblies which are possibly produced more or the ineffective yield of the low-grade power solar cell assemblies.

The greater the first match, the closer the number of premium power solar modules produced by such remaining solar cells is to the first number of premium power solar modules demanded by the assembly order, while ensuring that there is substantially no premium power byproduct. By analogy, the larger the second match amount, the more closely the second amount required for mid-range power solar modules in the assembly order is, the number of mid-range power solar modules produced by such remaining solar cells is guaranteed to be substantially free of mid-range power by-products. The larger the third matching amount, the more closely the third amount of solar modules required for low range power by the assembly order is, the more the number of low range power solar modules produced by such remaining solar cells is, with the assurance that there is substantially no low range power byproduct. Therefore, the sum of the high-grade power byproduct parameter corresponding to the remaining solar cell and the low-grade power byproduct parameter corresponding to the remaining 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 remaining solar cell to obtain the score corresponding to the solar cell.

In the embodiment of the present invention, the order may further include: an assembly parameter, which may include a non-downshift or a downshift. Non-downshifts and downshifts may be referred to in the foregoing description and will not be described herein in order to avoid redundancy. Referring to fig. 5, fig. 5 is a flowchart illustrating steps of determining a score of a solar cell in a case that a downshift parameter of an assembly order is a downshift according to an embodiment of the present invention. Optionally, in the case that the downshift parameter of the assembly order is a non-downshift, the step S117 may include:

and S1174, subtracting the first quantity corresponding to the assembly order form from the high-grade effective yield corresponding to the residual solar cells to obtain the gear reduction number corresponding to the residual solar cells.

And S1175, subtracting the third quantity corresponding to the assembly order from the low-grade effective yield corresponding to the residual solar battery pieces to obtain a low-grade power byproduct parameter corresponding to the residual solar battery pieces.

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

In the embodiment of the present invention, when the downshift parameter of a certain assembly order is downshift, that is, the solar cell module with middle-to-middle-to. Then, the first quantity corresponding to the assembly order is subtracted from the high-grade effective yield corresponding to the remaining solar cells, so as to obtain the downshift number corresponding to the remaining solar cells, that is, the quantity of high-grade power solar cell modules which are possibly produced more, and the quantity of solar cell modules which are required to be used as the medium-grade power solar cell modules. Although the whole part of the solar cell module is not wasted, the solar cell module with high-grade power is used as the solar cell module with middle-grade power, so that partial resource waste is caused, and invalid output is generated. The solar cell module with the medium-high power in the assembly order can be used as the solar cell module with the medium-high power, and the parameter of the high-grade power byproduct corresponding to the solar cell piece can be considered to be 0, namely the solar cell module with the high-grade power produced by the residual solar cell pieces is used up. By considering the downshift fraction, the control of the waste of resources or the ineffective output is more detailed, which is beneficial to further reducing the waste of resources or the ineffective output.

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

The greater the first match, the closer the number of premium power solar modules produced by such remaining solar cells is to the first number of premium power solar modules demanded by the assembly order, while ensuring that there is substantially no premium power byproduct. By analogy, the larger the second match amount, the more closely the second amount required for mid-range power solar modules in the assembly order is, the number of mid-range power solar modules produced by such remaining solar cells is guaranteed to be substantially free of mid-range power by-products. The larger the third matching amount, the more closely the third amount of solar modules required for low range power by the assembly order is, the more the number of low range power solar modules produced by such remaining solar cells is, with the assurance that there is substantially no low range power byproduct. Therefore, the low-gear power by-product parameter corresponding to the remaining solar cells can be subtracted by the sum of the first matching amount, the second matching amount and the third matching amount corresponding to the remaining solar cells, and then the downshift fraction corresponding to the downshift number is subtracted to obtain the fraction corresponding to the remaining solar cells.

Through distinguishing the difference of the downshift parameters, adopting a corresponding scoring mode to determine the corresponding scoring of the remaining solar cells, wherein the scoring principle is more corresponding to whether resource waste and invalid output can be generated, and finally, selecting the solar cell with the highest scoring from the plurality of remaining solar cells as the target solar cell corresponding to the assembly order, so that the degree of resource waste or invalid output generated by the selected target solar cell is smaller.

In this 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 potential waste of resources or an inefficient yield in the case where a high-power solar cell module is used as a medium-power solar cell module. And multiplying the total downshift number by a preset downshift coefficient to obtain the downshift fraction, wherein the downshift fraction can represent resource waste or ineffective output caused by all downshifts. The preset downshift coefficient may be set according to actual needs, and the like. In the embodiment of the present invention, this is not particularly limited.

In the embodiment of the invention, the scoring of the residual solar cells can reflect the matching degree of the residual solar cells and the assembly order. Therefore, the residual solar cell with the highest score can be determined as the target solar cell corresponding to the assembly order in a plurality of scores corresponding to the plurality of residual solar cells, and resource waste or invalid output can be further reduced.

In the embodiment of the invention, compared with the prior art that matched solar cells are manually selected for each order, due to different manual experiences and lack of scientific support, the selected solar cells are easy to cause resource waste and increase ineffective output. In the method, a plurality of orders are grouped, the orders with the same grouping parameters are divided into the same initial order group, and the orders of a plurality of solar cell modules are sequenced according to a preset rule to obtain sequencing numbers; sequentially determining the assembly orders corresponding to the sequencing numbers according to the sequence of the sequencing numbers from small to large; each order in the same assembly order and the order corresponding to the sequencing number are located in the same initial order group, and the assembly parameters of each order in the assembly order are the same; and counting to obtain a first quantity, a second quantity and a third quantity which are respectively needed 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 the highest score among the plurality of 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-grade module, the medium-grade module and the low-grade module corresponding to the solar cells. The method comprises the steps that the standards are unified in the process of determining target solar cells corresponding to an assembly order, the quantity required by each of solar cell assemblies with middle-high power, solar cell assemblies with middle-high power and solar cell assemblies with low-high power in the assembly order is directly and fully considered, the target solar cells determined for the assembly order are more objective and reasonable, and resource waste and invalid output can be avoided to a great extent; moreover, in the process of matching the solar cells, the solar cells with low consumption efficiency values can be preferentially consumed by performing the sequence from small to large according to the sequence numbers, by-products are reduced, and resource waste and invalid output can be avoided to a great extent.
