Description

Double glass photovoltaic module

technical field

The invention relates to a photovoltaic module, in particular to a double-glass photovoltaic module.

Background technique

Double-glass photovoltaic modules are mainly composed of two layers of glass, an encapsulating film between the glasses, and battery strings, which are laminated by a laminator to make it a whole. Although double-glass photovoltaic modules have many advantages, the following two problems still need to be further improved:

First, the two-layer glass structure of the double-glass module leads to the installation of the module on site, and the fixture of the conventional module is not suitable for the double-glass module. In the prior art, special double-glass fixtures are generally used to fix components. Since the surface of the double-glass module is glass, if the glass and the metal are in direct contact with the force, it is easy to cause the glass to burst. It is necessary to add two pieces of EPDM rubber to the fixture, but it is difficult to effectively combine the metal fixture and EPDM without loosening. If the manufacturing tolerance of the two is too small, the EPDM rubber is easy to deform or it is difficult to insert it into the metal fixture. If the manufacturing tolerance of the two is too large, it is easy to loosen and fall off. At the same time, it may be necessary to use multiple clamps to fix the photovoltaic module, which is inconvenient for on-site installation.

Second, because the double-glass photovoltaic modules use toughened glass, the corners of the toughened glass are very easy to hit hard objects during the subsequent on-site installation process, causing the module to burst. In the prior art, four plastic corner protectors are generally used to protect the four corners of the photovoltaic module, but such corner protectors can only be manually filled with silica gel by personnel and then manually installed on the four corners of the module, which is also inconvenient.

Contents of the invention

In view of this, the present invention provides a double-glass photovoltaic module, which can improve the convenience of on-site installation of the photovoltaic module, increase the mechanical strength of the photovoltaic module, and better protect the photovoltaic module.
