Problems solved by technology

[0003] Double-glass photovoltaic modules are prone to self-explosion during use. Since double-glass photovoltaic modules use glass instead of the backsheet, uneven stress during production and thermal expansion and contraction during use can easily lead to glass breakage , In addition, the fixture installation used in the installation of double glass modules will cause uneven extrusion force on the photovoltaic modules and also cause cracks

Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] see figure 1 , the present invention provides a technical solution: a double-glass photovoltaic module production process, comprising the following steps:

[0024] Step 1: Temper the glass. After the treatment, cut the tempered glass into the required size and prepare the EVA film with the same size as the tempered glass. Prepare the welding ribbon, battery sheet and frame for welding and rubber sleeves;

[0025] Step 2: Dedust the toughened glass, batteries, EVA film and other materials, then put the welding materials in the dust-free welding workshop, and then use the preheated welding torch to weld the batteries with welding tape;

[0026] Step 3: Lay the welded battery slices in the mold plate as required, and connect multiple battery...

Abstract

The invention relates to the technical field of photovoltaic modules, and discloses a double-glass photovoltaic module production process. The process comprises the following steps of 1, carrying outtoughening treatment on glass, cutting the toughened glass into the required sizes for spare use after the treatment is finished, and preparing an EVA adhesive film having the same size as the toughened glass for spare use; meanwhile, preparing a welding strip, a battery piece, a frame and a rubber sleeve strip which are required for welding; and 2, carrying out dust removal treatment on the materials, such as the tempered glass, the battery piece and the EVA adhesive film, etc. According to the present invention, in the production process, firstly, the tempered glass and the EVA adhesive filmare preheated at a low temperature, so that the tempered glass and the EVA adhesive film can be fully attached to the surfaces of the tempered glass and the battery piece after being softened, and then uneven stress caused by non-attachment can be avoided in the laminating process, so that the photovoltaic module is prevented from being broken; and meanwhile, the photovoltaic module is fixed in the frame by the rubber sleeve strips, so that a better protection and buffer effect is achieved on the thermal expansion and cold contraction of the photovoltaic module, and damage of extrusion forceto the photovoltaic module during installation is also avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a production process for double-glass photovoltaic modules. Background technique [0002] At present, solar photovoltaic power generation is a technology that converts light energy into electrical energy by using the photovoltaic effect of semiconductors. It is one of the effective ways to solve earth pollution and energy shortage. Compose the composite layer, and the photovoltaic cell module formed by connecting the wires in series and parallel to the lead terminal between the battery sheets can generate more electric energy. Tempered low-iron glass has higher strength and can withstand greater wind pressure and very large temperature differences between day and night. [0003] Double-glass photovoltaic modules are prone to self-explosion during use. Since double-glass photovoltaic modules use glass instead of the backsheet, uneven stress during production and ther...
