Referring to fig. 1, a schematic structural diagram of a photovoltaic module according to an embodiment of the present application is shown. Referring to fig. 2, a second schematic structural diagram of the photovoltaic module according to the embodiment of the present application is shown.
In this embodiment, the photovoltaic module 10 may specifically include: the photovoltaic lamination piece 11, the sealing piece 12 and the frame structure 13 arranged around the circumferential edge of the photovoltaic lamination piece 11; the frame structure 13 includes: the photovoltaic laminated part comprises a frame main body 130 with a cavity, wherein one side of the frame main body 130 is provided with an accommodating groove, the accommodating groove is provided with a groove bottom plate 131 and a groove side plate 132 arranged at one end of the groove bottom plate 131, and the photovoltaic laminated part 11 is partially arranged in the accommodating groove and is respectively connected with the groove bottom plate 131 and the groove side plate 132 in an adhesion manner; the sealing members 12 are respectively disposed between the photovoltaic laminate 11 and the tank bottom plate 131 and the tank side plate 132 to seal the gaps between the photovoltaic laminate 11 and the tank bottom plate 131 and the tank side plate 132.
In the embodiment of the present application, the photovoltaic laminate 11 includes glass, a cell sheet, an ethylene-vinyl acetate copolymer (EVA), a back sheet, a solder strip, and the like, including but not limited to a dual glass photovoltaic laminate or a single glass photovoltaic laminate.
In this embodiment, the accommodating groove has a groove bottom plate 131 and a groove side plate 132 disposed at one end of the groove bottom plate 131, that is, the groove bottom plate 131 and the groove side plate 132 form an L-shaped structure, when the pv laminate 11 is disposed in the accommodating groove, one side of the back electrode of the pv laminate 11 can be connected to the groove bottom plate 131, and the end surface of the side edge of the pv laminate 11 is opposite to the groove side plate 132, so that one side of the positive electrode of the pv laminate 11 is not shielded, therefore, in this embodiment, the light receiving area of the pv module 10 can be effectively increased, and further, the output power of the pv module 10 can be significantly increased.
In the present embodiment, the sealing member 12 may be disposed at the groove bottom plate 131 and the groove side plate 132 near the side edges of the length thereof to seal the gap between the photovoltaic laminate 11 and the groove bottom plate 131 and the groove side plate 132. In practical application, because the photovoltaic laminate 11 is usually bonded in the accommodating groove by EVA or other adhesives, the sealing member 12 is disposed between the photovoltaic laminate 11 and the groove bottom plate 131 and the groove side plates 132, which not only can prevent glue between the photovoltaic laminate 11 and the groove bottom plate 131 and the groove side plates 132 from overflowing, but also can play a role in buffering and dust sealing, thereby preventing hard contact between the photovoltaic laminate 11 and the groove bottom plate 131 and the groove side plates 132, and sealing gaps between the photovoltaic laminate 11 and the groove bottom plate 131 and the groove side plates 132, preventing rainwater and dust from accumulating in the gaps, prolonging the service life of the product, and improving the aesthetic property of the product.
In the embodiment of the present application, in order to improve the installation convenience of the sealing member 12, a first locking slot 1321 may be further provided on the slot side plate 132 at a position away from the side edge of the slot bottom plate 131; or, the first clamping slot 1321 is arranged at the position of the slot side plate 132 far away from the side edge of the slot bottom plate 131 and the position of the slot bottom plate 131 far away from the side edge of the slot side plate 132; one end of the sealing element 12 is embedded in the first clamping groove 1321, and the other end of the sealing element protrudes into the accommodating groove to be abutted to the photovoltaic laminated part 11. Specifically, in this embodiment of the application, the slot of the first card slot 1321 may be set to be a necking structure, that is, the slot width of the first card slot 1321 is smaller than the inner diameter of the first card slot 1321, so that the sealing element 12 and the first card slot 1321 may be in interference fit to fix one end of the sealing element 12 in the first card slot 1321, and not only the installation is simple and convenient, but also the structural stability of the sealing element 12 in the first card slot 1321 may be effectively improved.
In the embodiment of the present application, the first card slot 1321 may specifically be a U-shaped slot, a V-shaped slot, or a spherical cross-section-shaped slot. It will be appreciated that the shape of the sealing member 12 also matches the shape of the first card slot 1321 to make the connection between the sealing member 12 and the first card slot 1321 more reliable and stable.
In the embodiment of the present application, the end of the sealing member 12 protruding to the receiving groove and abutting against the photovoltaic laminate 11 may be a spherical structure or a truncated pyramid structure. For example, when the notch of the first clamping groove 1321 is necked, the sealing element 12 may have a structure similar to 8, one end of the 8 is disposed in the first clamping groove 1321, and the other end of the 8 protrudes into the accommodating groove to abut against the photovoltaic laminated part 11, so that the sealing element 12 can be stably embedded in the first clamping groove 1321, and the sealing element 12 can have sufficient compression allowance to play a better sealing and buffering role. Of course, in the case that the end of the sealing member 12 protruding to the accommodating groove and abutting against the photovoltaic laminate 11 is in a frustum structure, since the surface of the sealing member 12 abutting against the photovoltaic laminate 11 is a plane, the contact area between the sealing member 12 and the photovoltaic laminate 11 can be increased, and the sealing effect between the sealing member 12 and the photovoltaic laminate 11 is better.
It can be understood that, the frame structure 13 in the embodiment of the present application may be referred to as an a-side-free frame structure, and both the groove side plate 131 and the sealing member 12 are flush with the light receiving surface of the photovoltaic laminate 11, that is, both the end surface of the groove side plate 131 and the end surface of the sealing member 12 are on the same horizontal plane with the light receiving surface of the photovoltaic laminate 11, so that dust, water, and the like on the photovoltaic laminate 11 will not remain on the surface of the photovoltaic laminate, and the problem of water accumulation and dust resistance caused by the frame structure 13 can be effectively prevented.
In the embodiment of the present application, the sealing member 12 provided on the trough bottom plate 131 and the sealing member 12 provided on the trough side plate 132 may be the same or different. To better distinguish the above-described seal member 12, in the present embodiment, the seal member 12 may include a first seal member 121 and a second seal member 122; the first seal 121 is a seal disposed between the photovoltaic laminate 11 and the trough side plate 132, and the second seal 122 is a seal disposed between the photovoltaic laminate 11 and the trough bottom plate 131.
In the embodiment of the present application, since the first sealing member 121 is disposed between the photovoltaic laminate 11 and the groove side plate 132, that is, the gap between the photovoltaic laminate 11 and the groove side plate 132 is located on the positive electrode surface of the photovoltaic module 10 without being blocked, in the embodiment of the present application, the first sealing member 121 may specifically include at least one of a rubber strip and a silicone strip. In practical application, because the elastic rubber strip or the silica gel strip has good elastic sealing performance and good compression buffering performance, the rubber strip or the silica gel strip is used as a first sealing element to be arranged between the photovoltaic laminated part 11 and the groove bottom plate 131, so that hard contact between the photovoltaic laminated part 11 and the groove side plate 132 can be avoided, glue overflow can be effectively avoided, the service life of the photovoltaic module 10 is prolonged, and the appearance attractiveness is improved.
In the embodiment of the present application, since the second sealing member 122 is disposed between the photovoltaic laminate 11 and the trough bottom plate 131, the gap between the photovoltaic laminate 11 and the trough bottom plate 131 is usually located on the negative electrode side of the photovoltaic laminate 11, and the gap is blocked by the photovoltaic laminate 11, so that the second sealing member 122 has less influence on the appearance of the photovoltaic module 10, and the second sealing member 122 can be selected in a wider range compared to the first sealing member 121. In the embodiment of the present application, the second sealing element 122 may specifically include: at least one of rubber strip, silica gel strip, double-sided adhesive tape and single-sided adhesive tape.
In practical applications, both the first sealing element 121 and the second sealing element 122 can be disposed in the receiving groove by pasting. In this embodiment, the first card slot 1321 may be disposed on the slot side plate 132, and the rubber strip or the silicone strip may be clamped in the first card slot 1321, and the first card slot 1321 may be disposed on the slot bottom plate 131 or the first card slot 1321 may not be disposed. Specifically, under the condition that the first card slot 1321 is also arranged on the slot bottom plate 131, the first card slot 1321 and the second card slot 1323 may be the same, so as to reduce the processing difficulty, and thus, the second sealing member 122 may select a sealing member having the same structure as the first sealing member 121, and the types of parts of the photovoltaic module 10 may also be effectively reduced; in the case that the first card slot 1321 is not disposed on the slot bottom plate 131, the second sealing member 122 may be a double-sided tape or a single-sided tape, and the photovoltaic lamination member 11 is bonded by the double-sided tape or the single-sided tape, so that not only the glue overflow can be avoided, but also the buffer effect can be achieved to avoid the hard contact between the photovoltaic lamination member 11 and the frame structure 13.
In this embodiment of the application, in order to increase the adhesion reliability of the photovoltaic laminate 11 in the accommodating groove, optionally, the frame main body 130 is further provided with a glue storage groove 1311. The glue storage groove 1311 extends from the groove bottom plate 131 to the groove side plate 132 in the width direction of the glue storage groove 1311. That is to say, a part of the glue storage groove 1311 is disposed on the groove bottom plate 131, and the other part is disposed on the groove side plate 132, so that the glue storage groove 1311 is also disposed on the groove side plate 132, thereby effectively increasing the glue storage amount in the glue storage groove 1311, storing sufficient glue to improve the connection strength between the photovoltaic laminate 11 and the frame structure 13, and avoiding glue overflow. In the embodiment of the present application, the length direction of the glue storage groove 1311 is the length direction of the frame structure 13, and the width direction of the glue storage groove 1311 is the direction perpendicular to the length of the glue storage groove 1311.
Optionally, an anti-glue-overflow groove 1312 is further provided on at least one of the groove side plate 132 and the groove bottom plate 131 at a position close to the seal 12; the glue overflow preventing groove 1312 is communicated with the glue storage groove 1311, and the depth of the glue overflow preventing groove 1312 is greater than that of the glue storage groove 1311.
Referring to fig. 3, a third schematic structural diagram of a photovoltaic module according to an embodiment of the present application is shown. Referring to fig. 4, a fourth structural schematic diagram of the photovoltaic module according to the embodiment of the present application is shown.
In the embodiment of the present application, since there is a greater risk that glue overflows through a gap between the trough bottom plate 131 and the photovoltaic laminate 11 due to gravity, a glue overflow preventing trough 1312 having a deeper depth (here, the depth relative to the glue overflow preventing trough on the trough side plate 132) may be provided on the trough bottom plate 131, which is more advantageous in preventing glue overflow. That is, in practical applications, the shapes, depths, and the like of the glue overflow preventing grooves 1312 on the groove side plate 132 and the groove bottom plate 131 may be the same or different according to practical situations, and this is not particularly limited in the embodiment of the present application. In the embodiment of the application, the glue overflow preventing groove 1312 is arranged, so that the glue stock can be effectively increased, the bonding strength between the photovoltaic laminated board 222 and the frame structure 13 is increased, and glue overflow can be further avoided.
