Description

Technical Field

[0001] The utility model mainly relates to the technical field of photovoltaic panels, and in particular to a non-metal injection molding frame for photovoltaic panels. Background Art

[0002] During the use of flexible photovoltaic panels, adhesives and other processing methods are generally used to adhere the flexible photovoltaic panel components to the installation surface. Therefore, the frame of the flexible photovoltaic panel cannot use the aluminum alloy frame of the rigid structure photovoltaic panel. Usually, a metal sheet is used as the frame. During actual use, the metal sheet lacks limiting protection for the bending of the flexible photovoltaic panel, resulting in excessive bending and hidden cracks in the solar cells in the flexible photovoltaic panel.

[0003] When using an injection molded frame as the outer frame of a flexible photovoltaic panel, taking into account the bendable characteristics of the flexible photovoltaic panel and to avoid excessive bending of the flexible photovoltaic panel during use, the inventor proposed a non-metallic injection molded frame for a photovoltaic panel. By setting an anti-bending zone structure on the outside of the injection molded frame, excessive bending of the flexible photovoltaic panel and resulting in hidden cracks in the solar cell can be avoided.
