Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, specifically to a packaging structure, packaging method, and installation method for a photovoltaic module without an A-side. Background Technology

[0002] Conventional photovoltaic (PV) modules include those with an A-side and those without. PV modules with an A-side effectively prevent damage to the glass from collisions and pressure during packaging and transportation. However, because the top of the frame of a module with an A-side protrudes 2-3 millimeters above the front of the laminate, dust, debris, and rainwater can easily accumulate on the module when used outdoors, leading to hot spots and affecting power generation. PV modules without an A-side, lacking this feature, are less prone to dust and debris accumulation on the glass edges when used outdoors. However, the lack of frame protection on the front edge makes them susceptible to glass breakage from collisions and pressure during packaging and transportation. Furthermore, modules without an A-side cannot be installed using the standard module clamps, as these metal clamps directly fix the module to the A-side of the frame.

[0003] Therefore, a packaging structure is needed for photovoltaic modules without an A-side, which can not only meet the packaging requirements of photovoltaic modules without an A-side, but also effectively solve the problem of using clamps to install photovoltaic modules without an A-side. Summary of the Invention

[0004] To address at least one technical problem in the prior art, the present invention provides a packaging structure, packaging method, and installation method for photovoltaic modules without an A-side.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is: a packaging structure for photovoltaic modules without an A-side, comprising a tray on which multiple photovoltaic modules are placed, each photovoltaic module comprising a long frame, a short frame, and a laminate, wherein the long frame and the short frame do not have an A-side, and the laminate comprises a front glass, wherein the long frame and the short frame are not higher than the front glass;

[0006] At least two rubber pads are attached to the front side of each long side of the glass of the photovoltaic module. Each rubber pad has adhesive on only one side and the side of the rubber pad with adhesive is attached to the front side of the glass of the photovoltaic module.

[0007] The photovoltaic module is equipped with protective corner protectors at each of its four corners.

[0008] In some embodiments, the rubber gasket is adhered to the long side surface of the glass of the photovoltaic module, and the long side of the rubber gasket is flush with the edge of the long side of the glass of the photovoltaic module.

[0009] In some embodiments, the rubber pad is disposed in the non-powered area outside the battery cells of the laminate.

[0010] In some embodiments, the packaging corner protector includes an upper protective plate, a lower protective plate arranged opposite each other, and a right-angled side protective plate integrally disposed between the upper protective plate and the lower protective plate. The upper protective plate, the lower protective plate, and the side protective plate enclose a protective space with an opening and a corner.

[0011] The inner side of the upper guard plate is provided with a clearance groove at the position where it connects with the side guard plate;

[0012] The inner side of the lower guard plate is provided with a retaining edge, and the retaining edge and the side guard plate form a right-angled limiting groove.

[0013] In some embodiments, the side guard plate includes a first side connecting plate and a second side connecting plate perpendicular to the first side connecting plate;

[0014] The guard includes a first barrier and a second barrier perpendicular to the first barrier;

[0015] The first block is parallel to the first side connecting plate, and the second block is parallel to the second side connecting plate.

[0016] In some embodiments, there is a distance L1 between the first block and the first side connecting plate, and a distance L2 between the second block and the second side connecting plate, wherein the distances L1 and L2 are respectively adapted to the bottom width of the two adjacent frames of the photovoltaic module.

[0017] In some embodiments, the inner surface of the upper guard plate includes a protrusion that is completely unconnected to the side guard plate, and the protrusion and the side guard plate form the clearance groove.

[0018] In some embodiments, the width H of the clearance groove is 5-8 mm.

[0019] In some embodiments, the packaging corner protectors are made of PP or PVC.

[0020] The packaging method for photovoltaic modules without an A-side includes the following steps:

[0021] Before the component sorting process, at least two rubber pads are attached to the front of each long side of the front glass of the photovoltaic module. The photovoltaic module includes a long frame, a short frame and a laminate. The long frame and the short frame do not have an A-side. The laminate includes the front glass. The long frame and the short frame are not higher than the front glass.

[0022] After the component sorting process, packaging corner protectors are respectively installed at the four corners of the photovoltaic module. The packaging corner protectors include an upper protective plate, a lower protective plate and a right-angled side protective plate integrally set between the upper protective plate and the lower protective plate. The upper protective plate, the lower protective plate and the side protective plate form a protective space with an opening and corners. The inner side of the upper protective plate has a clearance groove at the position where it connects with the side protective plate. The inner side of the lower protective plate has a baffle. The baffle and the side protective plate form a right-angled limiting groove.

[0023] The photovoltaic modules are loaded into the tray;

[0025] The installation method for photovoltaic modules without an A-side includes the following steps:

[0026] After unpacking, take out the photovoltaic module, which includes a long frame, a short frame, and a laminate. The long frame and the short frame do not have an A-side. The laminate includes a front glass. The long frame and the short frame are not higher than the front glass. At least two rubber pads are attached to the front of each long side of the front glass. The four corners of the photovoltaic module are provided with packaging corner protectors. The packaging corner protectors include an upper protective plate, a lower protective plate, and a right-angled side protective plate integrally set between the upper protective plate and the lower protective plate. The upper protective plate, the lower protective plate, and the side protective plate form a protective space with an opening and corners. The inner side of the upper protective plate has a clearance groove at the position where it connects with the side protective plate. The inner side of the lower protective plate has a baffle. The baffle and the side protective plate form a right-angled limiting groove.

[0027] Transfer the photovoltaic modules onto the photovoltaic support and position them.

[0028] Remove the corner protectors from the packaging of the photovoltaic module;

[0029] Press the pressure block onto the rubber pad, and then use fasteners to fix the pressure block onto the photovoltaic bracket.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The packaging structure of the present invention has corner protectors and rubber pads. Both corner protectors and rubber pads can prevent the glass of the lower-layer photovoltaic module from directly contacting the frame of the upper-layer photovoltaic module during stacking or transportation, which would cause scratches or crushing on the glass surface of the lower-layer photovoltaic module. At the same time, the corner protectors can also protect the glass from being broken due to collision or squeezing during packaging and transportation.

[0032] 2. The rubber gasket of the present invention can be placed between the glass of the photovoltaic module without A-side and the pressure block when installing photovoltaic modules without A-side, effectively solving the problem of using pressure blocks to install photovoltaic modules without A-side.

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein. Therefore, the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] Reference Figures 1 to 4 A packaging structure for photovoltaic modules without an A-side is provided, including a tray on which multiple photovoltaic modules 3 are placed. Each photovoltaic module 3 includes a long frame, a short frame, and a laminate. The long frame and short frame do not have an A-side. The laminate includes a front glass. The long frame and short frame are not higher than the front glass. At least two rubber pads 1 are attached to the front of each long side of the front glass. Only one side of the rubber pad 1 has adhesive. The side of the rubber pad 1 with adhesive is attached to the front of the glass of the photovoltaic module 3. Packaging corner protectors 2 are provided at the four corners of the photovoltaic module 3.

[0040] In some embodiments, the rubber gasket 1 is adhered to the long side surface of the glass of the photovoltaic module 3, and the long side of the rubber gasket 1 is flush with the edge of the long side of the glass of the photovoltaic module 3.

[0041] In some embodiments, the rubber gasket 1 is disposed in the non-powered area outside the battery cells of the laminate.

[0042] In a preferred embodiment, the rubber gasket 1 is attached to the fixing point during the installation of the photovoltaic module 3. Thus, during the installation of the photovoltaic module 3, the rubber gasket 1 can be placed between the front glass and the pressure block 4, preventing the pressure block 4 from directly contacting the front glass of the photovoltaic module 3. This allows the pressure block 4 of conventional photovoltaic modules to also be used for the installation of photovoltaic modules without an A-side, effectively solving the problem of using the pressure block 4 to install photovoltaic modules without an A-side.

[0043] The orthographic projection of the pressure block 4 onto the front glass falls within the boundary envelope of the rubber gasket 1. Preferably, the rubber gasket 1 has a length of 55-65 mm, a width of 12-13 mm, and a thickness of 0.5-1.5 mm.

[0044] Reference Figure 2 The packaging corner protectors 2 include an upper protective plate 21 and a lower protective plate 22 arranged opposite each other, and a right-angled side protective plate 23 integrally arranged between the upper protective plate 21 and the lower protective plate 22. The upper protective plate 21, the lower protective plate 22 and the side protective plate 23 form a protective space with an opening and corners. When the photovoltaic module 3 is packaged or transported, the four corners of the photovoltaic module 3 are respectively inserted into the protective spaces of the four packaging corner protectors 2, and the packaging corner protectors 2 provide protection for the four corners of the photovoltaic module 3.

[0045] Furthermore, an anti-cavity groove 210 is provided on the inner side of the upper protective plate 21 at the position where it connects with the side protective plate 23. When the packaging corner protector 2 is snapped onto the outer corner of the photovoltaic module 3, the glass edge and glass corner of the photovoltaic module 3 are located within the anti-cavity groove 210 and do not contact the upper protective plate 21. Therefore, the glass edge and glass corner of the photovoltaic module 3 are not subjected to force, thereby preventing the photovoltaic module 3 from exploding during packaging and transportation.

[0046] Specifically, the inner surface of the upper guard plate 21 includes a protrusion 211 that is completely unconnected to the side guard plate 23, and the aforementioned clearance groove 210 is formed between the protrusion 211 and the side guard plate 23.

[0047] The protrusion 211 can be rectangular. When the protrusion 211 is rectangular, the clearance groove 210 is right-angled. The protrusion 211 can also be fan-shaped or other shapes.

[0048] After the packaging corner protector 2 is snapped onto the outer corner of the photovoltaic module 3, the protrusion 211 of the packaging corner protector 2 is tightly attached to the upper surface of the laminate of the photovoltaic module 3. The protrusion 211 is the main component that bears pressure and transmits pressure to the laminate. Therefore, the area occupied by the protrusion 211 on the inner side of the upper protective plate 21 is much larger than the area occupied by the clearance groove 210.

[0049] Preferably, the width H of the clearance groove 210 is 5-8mm.

[0050] In a preferred embodiment, the inner surface of the upper protective plate 21 further includes a first guide surface 212 connected to the protrusion 211. The first guide surface 212 is an arc surface and is disposed at the outer edge of the inner surface of the upper protective plate 21. The first guide surface 212 connects the outer end face of the upper protective plate 21 and the protrusion 211, so that there is a smooth transition between the outer end face of the upper protective plate 21 and the protrusion 211. The first guide surface 212 can be used to guide the packaging corner protectors 2 to be installed at the corners of the photovoltaic module 3, thereby facilitating personnel operation, and can also prevent the packaging corner protectors 2 from scratching the glass surface of the photovoltaic module 3 during installation and removal.

[0051] Furthermore, the inner side of the lower guard plate 22 is provided with a retaining edge 220, and the retaining edge 220 and the side guard plate 23 form a right-angled limiting groove 200. After the packaging corner protector 2 is engaged with the outer side of the corner of the photovoltaic module 3, the retaining edge 220 is engaged with the inner side of the bottom surface of the frame of the photovoltaic module 3, thereby fixing the packaging corner protector 2 and the photovoltaic module 3 relatively, and preventing the packaging corner protector 2 from detaching from the photovoltaic module 3 during handling or transportation.

[0052] Specifically, the guard 220 includes a first guard 221 and a second guard 222 perpendicular to the first guard 221;

[0053] The side panel 23 includes a first side connecting plate 231 and a second side connecting plate 232 perpendicular to the first side connecting plate 231. A first blocking plate 221 is arranged parallel to the first side connecting plate 231, and a second blocking plate 222 is arranged parallel to the second side connecting plate 232. There is a distance L1 between the first blocking plate 221 and the first side connecting plate 231, and a distance L2 between the second blocking plate 222 and the second side connecting plate 232. Distances L1 and L2 are respectively adapted to the bottom width of two adjacent frame 5s of the photovoltaic module.

[0054] In a preferred embodiment, the upper edge of the inner side of the edge 220 facing the side guard plate 23 is provided with a second guide surface 223. The second guide surface 223 is an inclined surface or an arc surface that is inclined away from the side guard plate 23. The second guide surface 223 is used to guide the first block 221 and the second block 222 to be inserted into the inner side of the bottom surface of the photovoltaic module 3, and also facilitates the removal of the packaging corner protector 2.

[0055] Furthermore, the packaging corner protectors are made of PP or PVC material, which has a certain degree of elasticity and good pressure resistance. While providing pressure cushioning and protecting the glass corners of the photovoltaic module 3, they also facilitate the installation of the packaging corner protectors 2 onto the outer edges of the photovoltaic module 3.

[0056] Based on the above installation structure, this patent also provides a packaging method for photovoltaic modules without an A-side, including the following steps:

[0057] Before the component grading process, at least two rubber pads 1 are attached to the front of each long side of the front glass of the photovoltaic module 3. The photovoltaic module 3 includes a long frame, a short frame and a laminate. The long frame and the short frame do not have an A side. The laminate includes the front glass. The long frame and the short frame are not higher than the front glass.

[0058] After the component sorting process, packaging corner protectors 2 are installed at the four corners of the photovoltaic module 3.

[0059] Load photovoltaic module 3 into the tray;

[0060] After the tray is filled with photovoltaic modules 3, it is packaged.

[0061] Based on the above installation structure, this patent also provides a method for installing photovoltaic modules without an A-side, including the following steps:

[0062] After unpacking, take out the photovoltaic module 3, which includes a long frame, a short frame and a laminate. The long frame and the short frame do not have an A side. The laminate includes the front glass. The long frame and the short frame are not higher than the front glass. At least two rubber pads 1 are attached to the front of each long side of the front glass. The four corners of the photovoltaic module 3 are provided with packaging corner protectors 2.

[0063] Transfer the photovoltaic module 3 onto the photovoltaic support 6 and position it.

[0064] Remove the corner protectors 2 from the packaging of photovoltaic module 3;

[0065] Press the pressure block 4 onto the rubber pad 1, and then use the fastener 5 to fix the pressure block 4 onto the photovoltaic bracket 6.
