Problems solved by technology

[0003] With the rapid development of photovoltaic power generation, double-glass solar modules have gradually become a hot spot in domestic photovoltaic power generation construction. However, there are many difficulties in the process of producing double-glass solar modules. The edge sealing of double-glass solar modules has always been a hot topic for discussion among major manufacturers. Topic, the conventional double-glass module without edge sealing makes the module fragile during transportation and installation, and at the same time, it is easy to form burrs on the edge during the cleaning process of double-glass solar module filling material EVA overflow glue, making the appearance ugly

Embodiment 1

[0034] Such as figure 1 As shown, a new double-glass solar module includes a double-glass solar module body 1 and wrapping 2, and the wrapping 2 is located around the double-glass solar module body 1.

[0035] The double-glass solar module body 1 includes a filling material 11, an upper glass 12 and a lower glass 13, the filling material 11 is located between the upper glass 12 and the lower glass 13, and the filling material 11 is EVA, POE or PVB.

[0036] The filling material 11 can also be pasted around the component body 1 using small strips made of EVA, POE and PVB.

[0037] After lamination, the double-glass solar module body 1 uses auxiliary tooling with air holes for edge sealing. The auxiliary tooling is made of high-temperature and high-pressure-resistant materials, and will not pollute the double-glass solar module during lamination. After the laminated double-glass solar module body 1 is cooled, the auxiliary tooling is torn off, and the overflowing filling materi...

Embodiment 2

[0043] A new double-glass solar module edge sealing method is improved on the basis of the conventional double-glass solar module production process. The process is as follows figure 2 shown, including the following steps:

[0044] In step S1, after the stacking of the double-glass solar module body is completed, use auxiliary adhesive tape to seal the sides of the double-glass solar module body.

[0045] The auxiliary tape has a hole in the center, good air permeability, high temperature and high pressure resistance, and covers all four sides of the double-glass solar body when sealing the edge. Only one tape is used for each side. The tape that is broken in the center cannot be continued, and each side is redundant. The tape needs to be cut off.

[0046] In step S2, the body of the double-glass solar module is laminated after the edge sealing, and the filling material of the body of the double-glass solar module overflows during the lamination process, forming an edge wrap...

Abstract

The invention discloses a novel double-glass solar module and an edge sealing method thereof. The double-glass solar module comprises a double-glass solar module body and a covered edge, wherein the covered edge is located on the periphery of the double-glass solar module body. The double-glass solar module body is edge-sealed by employing a heat resisting auxiliary tool having great permeability before lamination; after the laminated double-glass solar module body cools, the auxiliary tool is torn down, and overflowing filling materials of the double-glass solar module body automatically form the covered edge. The excessive glue covered edge makes module safety higher, and improves the fragile performance of a traditional double-glass solar module in an installation and transportation process; in addition, the excessive glue covered edge has greater resistance to moisture, and prolongs the service life of the module. The novel double-glass solar module is simple to operate, simplifies the steps of producing a double-glass solar module, and has a more beautiful appearance than a routine double-glass solar module.

Description

technical field [0001] The invention relates to photovoltaic power generation technology, in particular to a novel double-glass solar module and an edge sealing method thereof. Background technique [0002] Photovoltaic building integration is a new concept of applying solar power generation. Solar photovoltaic power generation arrays are installed on the outer surface of the building's maintenance structure to provide electricity. The combination of photovoltaic arrays and buildings is a commonly used form, especially with The combination of glass curtain wall. The double-glass solar module is a composite layer composed of two pieces of glass and solar cells, and the cells are connected in series and parallel to the lead terminals. [0003] With the rapid development of photovoltaic power generation, double-glass solar modules have gradually become a hot spot in domestic photovoltaic power generation construction. However, there are many difficulties in the process of prod...
