Referring to fig. 1, an embodiment of the present invention provides a photovoltaic system, including a plurality of photovoltaic modules 1, taking a photovoltaic system composed of two adjacent photovoltaic modules 1 as an example, a sealing member 2 made of rubber is disposed between two adjacent photovoltaic modules 1, the sealing member 2 includes a connecting portion 21, an attaching portion 22, and a matching portion 23, the connecting portion 21 is adhered to a lower surface of one of the photovoltaic modules 1 through an adhesive layer 3 and is adjacent to an edge 11 of the photovoltaic module 1, the attaching portion 22 is attached to the edge 11 where the photovoltaic module 1 is disposed, the attaching portion 22 has a connecting end 221 and a free end 222 that are disposed oppositely, the connecting end 221 is connected to the connecting portion 21, before two adjacent photovoltaic modules 1 are not assembled, the free end 222 protrudes from an upper surface of the photovoltaic module 1, an end face of the free end 222 is provided with a reflective layer 2221, the matching portion 23 is disposed on a side of the attaching portion 22 away from the connecting, the matching portion 23 is provided with an inclined plane 231, the height of one end of the inclined plane 231, which is close to the matching portion 22, is greater than the height of one end, which is far away from the matching portion 22, of the inclined plane 231, the lower end of another photovoltaic assembly 1 is matched with the inclined plane 231, the arrow indication direction in fig. 1 is the moving direction of another photovoltaic assembly 1, when two photovoltaic assemblies 1 are assembled, referring to fig. 2, the free end 222 can be retracted between two adjacent photovoltaic assemblies 1, so that the surface of the spliced photovoltaic system is smooth, and water guiding is facilitated.
In the embodiment of the invention, two photovoltaic assemblies 1 do not need to be bonded with a sealing element 2, so the two photovoltaic assemblies 1 can be disassembled after being spliced, and secondly, the requirement on the bonding accuracy of the sealing element 2 is not high during splicing of the bonding part 22, so that the construction difficulty is reduced, the height of the bonding part 22 of the sealing element 2 is higher than the upper surface of the photovoltaic assembly 1, so that the bonding part 22 of the sealing element 2 is blocked when the two photovoltaic assemblies 1 are spliced, the two photovoltaic assemblies 1 cannot be in direct contact, the effect of protecting the edge 11 of the photovoltaic assembly 1 during splicing is achieved, a reflecting layer 2221 arranged on the end surface of a suspended end 222 can reflect the sunlight irradiated on the sealing element 2, the direct sunlight is avoided, the aging rate of the sealing element 2 is reduced, in addition, the waterproof effect can also be achieved by sealing and shielding the gap between the two photovoltaic assemblies 1 through the sealing element 2, the arrangement adjustment efficiency and the maintenance efficiency of the photovoltaic system are integrally improved.
In a practical embodiment, the adhesive layer 3 for adhering the connecting portion 21 to the lower surface of the photovoltaic module 1 may be closely arranged to the attaching portion 22, however, in order to keep the distance between the attaching portion 22 and the edge 11 of the photovoltaic module 1 to be adjusted, in another embodiment, referring to fig. 1 and 2, the adhesive layer 3 and the attaching portion 22 may be arranged at a distance. When the adhesive layer 3 and the bonding portion 22 are arranged at an interval, the position between the adhesive layer 3 and the bonding portion 22 on the connecting portion 21 is not bonded to the photovoltaic module 1, and can move along with the elastic deformation of the sealing member 2. When the joint part 22 has a certain distance with the edge 11 of the photovoltaic module 1 and needs to be spliced and jointed, the part of the connecting part 21 which is not bonded with the photovoltaic module 1 can be retracted or bent and deformed, and the adjustment allowance of installation is reserved, so that the bonding accuracy of the sealing element 2 on the photovoltaic module 1 is reduced, the coating area of the adhesive layer 3 is also reduced, the splicing efficiency is improved, and the material cost is also reduced.
In one embodiment, referring to fig. 1 and 2, the end surface of the free end 222 may be further recessed with a reflective groove 2222, the reflective groove 2222 extends along the length direction of the sealing member 2, and a reflective layer 2221 is disposed on the groove wall of the reflective groove 2222. The reflective groove 2222 can not only bear the reflective layer 2221 on the groove wall, but also provide a water guiding function, so that water accumulation between the adjacent photovoltaic module 1 and the sealing member 2 is avoided.
Further, referring to fig. 1 and 2, when the portion of the connecting portion 21 that is not bonded to the photovoltaic module 1 is bent and deformed, a first concave groove 211 may be recessed in the connecting portion 21, the first concave groove 211 is located between the connecting portion 21 and the attaching portion 22, and one wall of the first concave groove 211 coincides with a side surface of the attaching portion 22 close to the connecting portion 21, in other words, the first concave groove 211 is smoothly transited between the attaching portion 22 and the connecting portion 21. By providing the first recess 211, internal stress at the time of bending deformation on the connecting portion 21 can be reduced, thereby reducing the risk of retraction of the fitting portion 22.

Meanwhile, the arc-shaped groove is convenient for the design and the use of a plastic mould during the production and the manufacture, and the effect of reducing the production cost is achieved.
Referring to fig. 1 and 2, the inclined surface 231 on the matching portion 23 may have a first end 2311 and a second end 2312 which are oppositely arranged, the height of the first end 2311 is greater than that of the second end 2312, the first end 2311 is adjacent to the attaching portion 22, that is, the inclined surface 231 is inclined from the first end 2311 to the second end 2312, when the photovoltaic module 1 to be spliced is placed on the second end 2312 of the sealing member 2, the photovoltaic module 1 to be spliced is guided to the first end 2311 along the inclined surface 231, and the second groove 232 is arranged between the first end 2311 and the attaching portion 22, so that the contact area of the first end 2311 and the lower surface of the photovoltaic module 1 can be reduced, and simultaneously, the material consumption of the sealing member 2 can be reduced.
Further, referring to fig. 1 and 2, the groove wall of the second groove 232 may form a circular arc transition structure with the second end 2312, when the spliced photovoltaic module 1 is detached from the fixed photovoltaic module 1, due to the existence of the circular arc transition structure between the groove wall of the second groove 232 and the second end 2312, the contact area between the second end 2312 and the lower surface of the spliced photovoltaic module 1 is further reduced, so that the friction force between the sealing member 2 and the spliced photovoltaic module 1 is reduced, and the detachment efficiency of the adjacent photovoltaic module 1 is accelerated.
Since the sealing member 2 is an elastic member made of rubber, the attaching portion 22 and the fitting portion 23 may fall down by a certain amount due to the influence of gravity, and in order to ensure close fitting between the attaching portion 22 and the fitting portion 23 and the photovoltaic module 1 to be spliced, in another embodiment, referring to fig. 1 and 2, the height of the first end 2311 may be set higher than the height of the connecting portion 21, thereby reducing the amount of the falling down displacement of the attaching portion 22 and the fitting portion 23 due to the influence of gravity. In the present embodiment, the height of the first end 2311 is set to be higher than the height of the connection portion 21, and the fitting portion 23 of the seal 2 is in an upturned state with respect to the connection portion 21 before splicing.
For the adhesive layer 3 between the sealing member 2 and the photovoltaic module 1, the adhesive strength between the adhesive layer 3 and the sealing member 2 is different, and in order to avoid the adhesion failure caused by too low adhesive strength, in one embodiment, a rubber treatment agent is coated on the connecting portion 21, or on the surface of the adhesive layer 3 adhered to the connecting portion 21, or on the connecting portion 21 and on the surface of the adhesive layer 3 adhered to the connecting portion 21, so as to enhance the adhesive strength between the adhesive layer 3 and the sealing member 2.
