Technical Field

The invention relates to the technical field of photovoltaic module production, in particular to a photovoltaic module production system and a production method.

Background

In the prior art, a back contact solar cell module realizes conductive interconnection between back contact cells through a conductive back plate. The conductive back plate is formed by laminating a conductive metal foil layer, an insulating medium layer, an Ethylene-Vinyl Acetate Copolymer (EVA) layer and a back plate layer. The material of the conductive metal foil layer is generally copper foil or aluminum foil. The conductive metal foil needs to be subjected to patterning treatment to form an electrically isolated pattern, so that the conductive metal foil can be conveniently and respectively electrically connected with the anode and the cathode of the back contact solar cell, and the conductive material electrically connects the conductive metal foil with the back electrode of the back contact cell piece through the insulating medium layer.

In the preparation of a back contact solar cell module, it is generally required to print a conductive material on a conductive back plate, the number of printed dots is large (for example, 60 back contact solar cell modules need to print at least thousands of conductive material dots), and then lay a back contact cell on the conductive back plate, so as to align the back electrode of the back contact cell with the conductive material dots. And finally, laying a front EVA (ethylene-vinyl acetate) layer or a POE (Polyolefin Elastomer; Chinese full name: ethylene-octene copolymer) layer and a glass cover plate on the back contact cell piece, and laminating.

At present, no automatic production and processing equipment for producing the back contact solar cell module exists, and the operations are all completed manually. Even if the conventional automatic production equipment for the non-back-contact solar cell module is used, due to the fact that the aligning requirement of the large number of conductive material points and the back-contact cell pieces is extremely high, defective products or unqualified products are prone to occurring on the back-contact solar cell module, and the back-contact solar cell module can only be manually repaired. When needing to be repaired, the unqualified products needing to be repaired can not be automatically conveyed to the repair station. The existing repair mode can not realize automatic repair, has low repair efficiency and seriously restricts the production and popularization of the back contact solar cell module.

The rework station 300 is located at a first end of the second transfer mechanism 200. The rework mechanism is located at rework station 300.

In the case where the photovoltaic laminate at any of the feeding stations is an unacceptable product, the photovoltaic laminate is transported along the first transport mechanism 100 and the second transport mechanism 200 to the rework station.

Compared with the prior art, the photovoltaic module production system provided by the invention comprises the first conveying mechanism 100, the second conveying mechanism 200, the repair station 300 located at the first end of the second conveying mechanism 200 and the repair mechanism located at the repair station 300. In the process of producing the photovoltaic module, whether the corresponding photovoltaic laminated member is a qualified product or not can be automatically detected at the corresponding feeding station, and when the photovoltaic laminated member at any feeding station is an unqualified product, the photovoltaic laminated member is conveyed to a repair mechanism along the first conveying mechanism 100 and the second conveying mechanism 200 for repair. Based on this, realized photovoltaic module production system in the production process, carried out intelligent automatic repair to photovoltaic laminated member. At the rework station 300, after the rework mechanism reworks the photovoltaic laminate that is an unqualified product, the photovoltaic laminate is conveyed to the first conveying mechanism 100 again for a corresponding feeding operation.

The photovoltaic module products are of various types, and the embodiment of the invention is described by taking the photovoltaic module as a back contact solar cell as an example.

Referring to fig. 1, each of the first transfer mechanism 100 and the second transfer mechanism 200 may be a linear type transfer mechanism. The linear conveyor mechanism may include, but is not limited to, a linear conveyor mechanism. The first conveying mechanism 100 may be formed by sequentially connecting a plurality of first sub-conveying mechanisms, each of which corresponds to a corresponding feeding mechanism. That is, each first sub-conveyance mechanism forms one loading station.

Referring to fig. 1, the above-mentioned various feeding mechanisms may sequentially include along a feeding conveying direction: a backplane feeding mechanism 401, a battery sheet feeding mechanism 402, a packaging material feeding mechanism 403, and a cover feeding mechanism 404, but not limited thereto. It should be understood that the type of loading mechanism is related to the type of photovoltaic module.

Referring to fig. 1, the backplane feeding mechanism 401 may be used to provide a conductive backplane with a preset conductive circuit, so as to electrically connect to the battery cells stacked on the conductive backplane. The cell loading mechanism 402 may be used to arrange the cells on the conductive backplane, and the cells are electrically connected to the conductive circuit on the conductive backplane. In practical application, the battery piece may be a back contact battery piece, including: IBC (International rear contact) solar cell or MWT (Metal Wrap Through) solar cell.

The encapsulating material may include: one or more of epoxy resin, acrylic resin, polyurethane, cyanoacrylate, Polyvinyl alcohol, polydimethylsiloxane, ethylene-vinyl acetate copolymer (EVA for short), ethylene-octene copolymer (POE for short), Polyvinyl Butyral (PVB for short) or silicone.

Referring to fig. 1, the cap loading mechanism 404 may be used to stack a cap material onto a packaging material. The cover plate may be made of Polyethylene Terephthalate (PET), Polyethylene (PE), olefin resin, resin film such as fluorine-containing resin or silicone-containing resin, or light-transmitting plate-shaped resin member such as glass, polycarbonate, or acrylic resin.

In one possible implementation manner, the photovoltaic module production system may further include: printing mechanism, lobe of a leaf mechanism and battery piece composing mechanism. The printing mechanism, the splitting mechanism and the cell typesetting mechanism may be sequentially disposed between the cell feeding mechanism 402 and the packaging material feeding mechanism 403. In some cases, the cell loading mechanism 402, the printing mechanism, the breaking mechanism, and the cell typesetting mechanism may be integrated together. The printing mechanism can be used for printing the conductive material on the back contact battery piece, and the splitting mechanism can be used for splitting the printed back contact battery piece. The cell piece composing mechanism is internally provided with a hot pressing mechanism for carrying out hot pressing treatment on the back contact cell piece arranged on the conductive backboard, so that the back contact cell piece is fixedly attached to the conductive backboard, and the problem that the performance of the photovoltaic module is poor due to the fact that the back contact cell piece composed on the conductive backboard is displaced and deflected in the conveying process is solved.

In a possible implementation manner, the first conveying mechanism 100 may further include a plurality of stacks thereon for buffering the corresponding photovoltaic stacks or the corresponding materials. Specifically, a stack may be disposed beside the feeding mechanism at each feeding station, or a stack may be disposed beside a feeding station that consumes a relatively long time. All of the stacks may be located on one side of the feed mechanism in the feed conveyance direction of the first conveyance mechanism 100. The first conveying mechanism 100 is communicated with the corresponding stacks, continuous operation can be achieved through the stacks, the situation that the feeding mechanism is idle is avoided, and the productivity of the photovoltaic module production system is improved.

In one possible implementation manner, the photovoltaic module production system may further include: the loading device comprises a plurality of loading trays with a data storage function, a plurality of detection devices, a plurality of first reading-writing devices and a plurality of loading control devices.

The bearing tray is used for bearing raw materials of the photovoltaic lamination or the photovoltaic lamination and recording production information of the photovoltaic lamination. Each detection device is arranged at a corresponding feeding station and/or the repair station and is used for detecting and generating quality information of a corresponding photovoltaic laminated member. Each first read-write device is arranged at the corresponding feeding station and/or the repair station, is communicated with the corresponding detection device, and is used for acquiring production information and updating the production information on the bearing tray according to the quality information and/or the material information of the corresponding feeding station. Each feeding control device is arranged at the corresponding feeding station and is communicated with the corresponding first reading-writing device, and the feeding control devices are used for controlling the corresponding feeding mechanisms to carry out feeding operation according to the production information. From the above, the production information of the photovoltaic laminate may include: quality information of the photovoltaic laminated member and material information of a corresponding feeding station.

The bearing surface of the bearing tray can be provided with a passive anti-metal electronic tag for storing production information of the photovoltaic laminated member. The passive anti-metal electronic tag can comprise an antenna unit and an electronic tag chip. The antenna unit is electrically connected with the electronic tag chip and used for receiving the radio-frequency signal and converting the radio-frequency signal into induction current to be supplied to the electronic tag chip. And the electronic tag chip is used for storing the production information of the photovoltaic laminated piece and returning the production information of the photovoltaic laminated piece to the first read-write equipment through the antenna unit under the energy of the induced current.

The first read-write device may be an electronic tag read-write device. And each feeding station can be provided with an electronic tag reading-writing device for sending radio frequency signals to the passive anti-metal electronic tag so that the passive anti-metal electronic tag returns self-stored production information.

It should be understood that a first read-write device and a detection device are also required to be arranged at the rework station 300, the first read-write device is used for reading production information on the carrier tray to determine specific production information of an unqualified photovoltaic laminated part and rework the unqualified photovoltaic laminated part according to the specific production information, and the detection device is used for detecting and generating corresponding quality information of the repaired photovoltaic laminated part. After the rework is completed, the first read-write device at the rework station 300 updates the production information on the carrier tray.

In the practical application process, the working process of the photovoltaic module production system can be as follows: in the feeding and conveying direction of the first conveying mechanism 100, that is, the carrier tray passes through the backplane feeding mechanism 401, the battery pack feeding mechanism 402, the encapsulating material feeding mechanism 403, the cover feeding mechanism 404, and the like in sequence along the first conveying mechanism 100. After each feeding mechanism, various materials are sequentially stacked on the bearing tray to form the photovoltaic stacked member. That is, the materials that make up the photovoltaic stack are updated in sequence as the carrier tray is conveyed in the direction of feed conveyance. Before the loading is carried out at the corresponding loading station, the first reading-writing equipment reads the production information on the bearing tray.

When the corresponding feeding control equipment confirms that the photovoltaic laminated members on the bearing tray are qualified products according to the production information, the feeding control equipment controls the corresponding feeding mechanism to execute feeding operation. At the moment, the first reading-writing equipment can update the production information on the bearing tray according to the material information of the current feeding station. For example, the updated production information may include: the battery piece is loaded. After the feeding is completed, the corresponding detection equipment detects the photovoltaic laminated member and generates quality information of the corresponding photovoltaic laminated member. At this time, the first read-write device updates the production information on the bearing tray according to the quality information. For example, the updated production information may include: and (4) loading the battery piece, and obtaining a qualified product.

When the corresponding feeding mechanism confirms that the photovoltaic laminated piece on the bearing tray is an unqualified product according to the production information, the feeding mechanism does not execute feeding operation. At this moment, the first read-write equipment can update the production information on the bearing tray according to the quality information of the photovoltaic laminated member and the material information of the current feeding station. For example, the updated production information may include: the back plate is loaded, unqualified products need to be repaired, and the battery piece is not loaded. Photovoltaic stacks judged to be defective products are conveyed directly to the repair mechanism along the first conveying mechanism 100 and the second conveying mechanism 200.

At rework station 300, the rework mechanism reworks the photovoltaic stack after the first read-write device reads the production information on the carrier tray. After the photovoltaic laminated member is repaired, the repaired photovoltaic laminated member is detected through corresponding detection equipment to generate quality information of the corresponding photovoltaic laminated member, and then the first read-write equipment updates production information on the bearing tray. For example, the updated production information may include: the back plate is loaded, the qualified product is repaired, and the battery piece is not loaded. The reworked photovoltaic laminated member is conveyed to the first conveying mechanism 100, production information on the bearing tray is read through corresponding first reading and writing equipment, and the reworked photovoltaic laminated member can conveniently and quickly find the next feeding station.

It should be understood that manual rework may also be used to rework an unacceptable photovoltaic stack at the rework station 300. The specific operation can be selected according to actual conditions.

In conclusion, by adopting the first read-write equipment and the bearing tray with the data storage function, the material information included in the corresponding photovoltaic laminated member and the specific position of the photovoltaic laminated member generating unqualified products, namely the production information of the photovoltaic laminated member, can be conveniently recorded, so that the mechanism can be conveniently repaired to accurately repair the photovoltaic laminated member, and the repair efficiency is improved.

In one possible implementation manner, the photovoltaic module production system may further include: tray feed mechanism. Tray feed mechanism can be located the front end of backplate feed mechanism 401 for in photovoltaic module production process, provide and bear the tray to bear the material of follow-up material loading station, form corresponding photovoltaic pile of parts in proper order.

In a possible implementation manner, alarm devices may be further disposed at the feeding stations, and each alarm device is in communication connection with a corresponding feeding control device. Specifically, when the first read-write equipment at the corresponding feeding station reads wrong production information, the corresponding feeding control equipment can control the corresponding alarm equipment to give an alarm, and the corresponding alarm equipment is manually used for processing and eliminating faults. The erroneous production information may include: the information of the bearing tray is accidentally inserted by a person, the information which is not changed in time after the operation is finished at the previous feeding station, the first reading-writing equipment fails or the electronic tag on the bearing tray fails.

In one example, when the production information recorded on the bearing tray is "the back plate is loaded, the unqualified product needs to be repaired, and the battery piece is not loaded", and the first read-write device at the back plate loading station reads the information, the alarm device at the back plate loading station gives an alarm. Because when this production information is present, the carrier tray carrying the photovoltaic stack is only likely to be present at the rework station 300.

In a possible implementation manner, referring to fig. 2, the photovoltaic module production system may further include: a third transport mechanism 500 and a lamination mechanism. The third transfer mechanism 500 has a first end and a second end distributed along the transfer direction of the first transfer mechanism 100. The first end of the third transfer mechanism 500 is connected to the second end of the first transfer mechanism 100. A lamination mechanism is disposed at a second end of the third conveyor 500 for performing a lamination operation on the photovoltaic stack.

Specifically, when the photovoltaic laminate is identified as a good product at the last feeding station, the photovoltaic laminate is transported along the second end of the first transport mechanism 100 to the first end of the third transport mechanism 500 and then transported by the third transport mechanism 500 to the laminating mechanism for lamination.

In one possible implementation manner, the photovoltaic module production system may further include a first transfer control mechanism. The first transfer control mechanism is disposed between the first transfer mechanism 100 and the second and third transfer mechanisms 200 and 500. The second end of the first transfer mechanism 100 may be selectively communicated with the second end of the second transfer mechanism 200 and/or the second end of the first transfer mechanism 100 may be selectively communicated with the first end of the third transfer mechanism 500 by the first transfer control mechanism.

In one possible implementation, referring to fig. 1, the first transfer control mechanism may include a first lift mechanism 600. One end of the first elevating mechanism 600 is connected to the second end of the first transfer mechanism 100, the other end of the first elevating mechanism 600 is connected to the second end of the second transfer mechanism 200, and the first end of the third transfer mechanism 500 is connected to the middle end of the first elevating mechanism 600. As a result, the first lifting mechanism 600 can connect the first transfer mechanism 100, the second transfer mechanism 200, and the third transfer mechanism 500.

In one possible implementation manner, referring to fig. 1, the photovoltaic module production system may further include a second reading and writing device and tray separation mechanism 700 in communication with the first transport control mechanism. The second reading and writing device is arranged at the second end of the first conveying mechanism 100 and is used for acquiring the production information on the bearing tray. The second read-write device and the first read-write device may have the same structure and function, and are not described herein again.

In the case where it is determined that the photovoltaic laminated member is a qualified product based on the production information acquired by the second read-write apparatus, the tray separation mechanism 700 separates the carrier tray from the photovoltaic laminated member. The communication between the second end of the first transfer mechanism 100 and the second end of the second transfer mechanism 200 transfers the empty load pallet to the second transfer mechanism 200. The photovoltaic stack is transported to a second end of the third transport mechanism 500 via communication between the second end of the first transport mechanism 100 and the first end of the third transport mechanism 500.

Under the condition that the photovoltaic laminated piece is determined to be an unqualified product according to the production information acquired by the second read-write equipment, the first conveying control mechanism conveys the bearing tray bearing the photovoltaic laminated piece to the second conveying mechanism 200 through the communication between the second end of the first conveying mechanism 100 and the second end of the second conveying mechanism 200.

In an actual application process, when the carrying tray carrying the photovoltaic laminated member is conveyed to the tray separating mechanism 700, the second reading and writing device reads production information on the carrying tray, so that the first transmission control mechanism can conveniently control the tray separating mechanism 700 to separate the carrying tray from the photovoltaic laminated member according to whether the production information needs to be obtained.

Specifically, when the photovoltaic laminate is identified as a good product, the first conveyance control mechanism controls the tray separation mechanism 700 to perform a separation operation on the carrier tray carrying the photovoltaic laminate. After the carrier tray and the photovoltaic stacked member are separated, the first transfer control mechanism controls the tray separating mechanism 700 to place the photovoltaic stacked member at the second end of the first transfer mechanism 100, and controls the second end of the first transfer mechanism 100 and the first end of the third transfer mechanism 500 to communicate with each other through the first lifting mechanism 600. The photovoltaic laminate is conveyed along the first conveying mechanism 100, the first lifting mechanism 600 and the third conveying mechanism 500 to a laminating mechanism, and the laminating mechanism laminates the photovoltaic laminate. Then, the first transfer control mechanism controls the tray separating mechanism 700 to place the carrying tray at the second end of the first transfer mechanism 100, and controls the second end of the first transfer mechanism 100 and the second end of the second transfer mechanism 200 to communicate with each other through the first lifting mechanism 600, and the empty carrying tray is transferred to the first end of the second transfer mechanism 200 along the first transfer mechanism 100, the first lifting mechanism 600 and the second transfer mechanism 200, so as to start a new round of loading operation.

When the photovoltaic laminated piece is determined to be an unqualified product, the first conveying control mechanism controls the tray separation mechanism 700 not to execute separation operation, the bearing tray bearing the unqualified photovoltaic laminated piece is conveyed to the repair station 300 along the first conveying mechanism 100, the first lifting mechanism 600 and the second conveying mechanism 200, and the unqualified product is repaired by the repair mechanism.

In one possible implementation, referring to fig. 2, the photovoltaic module production system further includes a fourth transfer mechanism 800. The fourth conveyance mechanism 800 has a first end and a second end distributed in the conveyance direction of the second conveyance mechanism 200. The first end of the fourth conveyor 800 is connected to the first end of the second conveyor 200, and the rework station 300 is located at the second end of the fourth conveyor 800.

In the case where the photovoltaic laminate at any of the feeding stations is an unacceptable product, the photovoltaic laminate is transported along the first transport mechanism 100, the second transport mechanism 200, and the fourth transport mechanism 800 to the rework station 300. The reworked photovoltaic stack is transferred to a first transfer mechanism 100.

Specifically, in the case where the photovoltaic module production system includes the first lifting mechanism 600, when the photovoltaic module is determined to be an unqualified product, the photovoltaic laminate is conveyed to the rework station 300 along the first conveyance mechanism 100, the first lifting mechanism 600, the second conveyance mechanism 200, and the fourth conveyance mechanism 800. The reworked photovoltaic stack is transferred to a first transfer mechanism 100.

In one possible implementation, referring to fig. 2, the first end of the second conveying mechanism 200 is connected to the first end of the first conveying mechanism 100. The photovoltaic module production system may further include a second conveyance control mechanism. Is disposed between the first end of the first transfer mechanism 100 and the first ends of the second transfer mechanism 200 and the fourth transfer mechanism 800. The first end of the first transfer mechanism 100 may be selectively communicated with the first end of the second transfer mechanism 200 or the first end of the first transfer mechanism 100 may be selectively communicated with the first end of the fourth transfer mechanism 800 by the second transfer control mechanism.

In one possible implementation, referring to fig. 4, the second transfer control mechanism includes a second lifting mechanism 900. One end of the second elevating mechanism 900 is connected to the first end of the first transfer mechanism 100, and the other end of the second elevating mechanism 900 is connected to the first end of the second transfer mechanism 200. A first end of the fourth transfer mechanism 800 is connected to an intermediate end of the second elevating mechanism 900.

In a possible implementation manner, the photovoltaic module production system may further include a third read-write device. The third read-write device is arranged at the first end of the first conveying mechanism 100 and is used for clearing production information on the unloaded bearing tray.

In the practical application process, the third reading and writing device clears the production information on the empty bearing tray at the first end of the first conveying mechanism 100, so that the situation that the information is disordered on the bearing tray in the new feeding process is avoided.

In one possible implementation, with reference to fig. 1 and 3, the first transfer control mechanism further comprises a first sensor device; the second conveyance control mechanism further includes a second conveyor apparatus. The first sensor device is used to detect whether the photovoltaic stack, a carrier tray carrying the photovoltaic stack, or an empty carrier tray is being conveyed onto first lift mechanism 600. Similarly, a second sensor device is used to detect whether a carrier tray carrying a photovoltaic stack or an empty carrier tray is being transported to the second lifting mechanism 900.

Specifically, referring to fig. 4, the first lifting mechanism 600 may include a supporting plate and a supporting frame slidably connected to the supporting plate. The carrier plate is used for carrying the photovoltaic laminate or a carrier tray carrying the photovoltaic laminate or an empty carrier tray. In the operation process of the first lifting mechanism 600, the bearing tray can move up and down along the supporting frame, and the first transmission control unit can control the stroke of the bearing plate on the supporting frame according to the data of the sensor device.

It should be appreciated that the thicknesses of the empty carrier tray, the photovoltaic stack, and the carrier tray carrying the photovoltaic stack are not uniform. Therefore, in practical applications, only the photovoltaic stack, the carrier tray carrying the photovoltaic stack, or the empty carrier tray is conveyed to the first lifting mechanism 600 according to the thickness judgment obtained by the first sensor device. Based on this, the height of the carrier plate moving along the support frame may be consistent with the height of the first, second or third transmission mechanisms 100, 200 or 500, respectively.

Similarly, the structure of the second lifting mechanism 900 is the same as that of the first lifting mechanism 600, and the operation principle is the same, which is not described herein again.

In a possible implementation manner, the first lifting mechanism 600 may have a fourth read-write device and an alarm device, and both the fourth read-write device and the alarm device are in communication connection with the first transmission control mechanism. In the process of operating the first lifting mechanism 600, the fourth reading and writing device included in the first lifting mechanism 600 can read the production information on the carrying tray, when the fourth reading and writing device reads the production information twice within the set threshold time, it indicates that the production information on the carrying tray is incorrect, the first transmission control mechanism controls the alarm device to give an alarm, and the fault is manually checked and processed.

The production flow of the photovoltaic module production system is described below when the photovoltaic laminated member is respectively a qualified product or an unqualified product.

In one example, at the cover sheet feeding station, when a feeding control device at the cover sheet feeding station determines that the photovoltaic laminate is a qualified product according to the production information read by the first read-write device, the feeding control device controls the cover sheet feeding mechanism 404 to perform a cover sheet material feeding operation. After the cover plate material is fed, the first reading-writing device at the cover plate feeding station updates the production information of the photovoltaic laminated member. After the carrier tray carrying the photovoltaic laminated member is conveyed to the tray separation mechanism 700 along the first conveying mechanism 100, and when the first conveying control mechanism determines that the photovoltaic laminated member is a qualified product according to the production information read by the second reading and writing device, the first conveying control mechanism controls the tray separation mechanism 700 to separate the carrier tray carrying the photovoltaic laminated member, and the first conveying control mechanism controls the tray separation mechanism 700 to place the photovoltaic laminated member on the second end of the first conveying mechanism 100. The photovoltaic laminate is transported along the first transport mechanism 100, the first lifting mechanism 600, and the third transport mechanism 500 to a laminating mechanism, which laminates the photovoltaic laminate. After the photovoltaic stack is separated from the carrier tray, the first transfer control mechanism controls the tray separation mechanism 700 to place an empty carrier tray on the second end of the first transfer mechanism 100. The empty load tray is conveyed to the first end of the first conveying mechanism 100 along the first conveying mechanism 100, the first lifting mechanism 600, the second conveying mechanism 200 and the second lifting mechanism 900, and the third reading and writing device clears the production information on the empty load tray so as to start a new loading operation.

In another example, at the station of the cover plate feeding mechanism 404, when the feeding control device at the cover plate feeding station determines that the photovoltaic stack is an unqualified product according to the production information read by the first reading and writing device, the feeding control device controls the cover plate feeding mechanism 404 not to perform the feeding operation. And updating the production information of the photovoltaic laminated member by first reading-writing equipment at the cover plate feeding station. When the first conveyance control mechanism determines that the photovoltaic laminate is an unqualified product according to the production information read by the second reading and writing device after the carrier tray carrying the photovoltaic laminate is conveyed to the tray separation mechanism 700 along the first conveyance mechanism 100, the first conveyance control mechanism controls the tray separation mechanism 700 not to execute the separation operation. The carrier tray carrying the unqualified photovoltaic laminate is conveyed to the repair mechanism along the first conveying mechanism 100, the first lifting mechanism 600, the second conveying mechanism 200, the second lifting mechanism 900 and the fourth conveying mechanism 800, and the unqualified photovoltaic laminate is repaired by the repair station 300. The first read-write equipment at the repair station 300 is convenient for the repair mechanism to carry out accurate repair by reading the production information on the bearing tray, and the repair work efficiency is improved. Meanwhile, the next feeding station is found out fast by the repaired photovoltaic laminated member conveniently.
