Problems solved by technology

[0004] Double-glass modules commonly used in photovoltaic power generation use double-layer 2.5mm glass and frameless design. For this design, the main method is to directly press the pressing block on the edge of the glass for installation, and fix it with rubber skin. This installation method, the rubber skin It is easy to age, and has poor durability for long-term installation. Its weight is larger than conventional components, and its installation structure is different from conventional components. It is not as widely used in large-scale fields such as ground power stations as conventional components. The weight of the components, with a frame to ensure its stable structure and easy installation

Abstract

The invention discloses a preparation process of a lightweight double-glazed module with a frame. The preparation process comprises the following steps: preparing a high-transmission type EVA coating;preparing a double-glazed module; performing primary EL testing; performing lamination package; performing the second EL testing; adding the frame, and accessing into a terminal box; and performing the third EL testing. The scattering of the sunlight is reduced by using the high-transmission type EVA coating, so that the solar cell can receive more sunlight, and the photoelectric efficiency of the solar cell is improved; the bottom super-white embossed tempered glass and surface super-white semi-tempered glass with small thickness are used, a light refraction path and a light reflection pathare reduced, the light transmission energy loss is reduced, the utilization efficiency of the light is improved, and the generating capacity of the module is improved by about 5%. By adopting the frame made of aluminum alloy, the double-glazed module is lighter, and the mounting is simple; a solar cell string and two layers of glass in the manufactured double-glazed module are tightly adhered, thebubbles are inexistent, and the module quality is high.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a preparation process of a lightweight double-glass module with a frame. Background technique [0002] With the depletion of conventional fossil energy and the deterioration of the ecological environment, the energy crisis has become the main contradiction in the current international social and economic development. In order to solve this major crisis, all countries in the world are working hard to explore new energy sources. Permanent energy source solar. With the continuous development of the photovoltaic industry, more and more countries and regions hope to use clean photovoltaic energy. The emergence of double-glass power generation modules meets people's demand for using photovoltaic energy in areas with harsh environments, allowing more and more people to enjoy the beauty brought by photovoltaics. [0003] Generally, the front and back sides of the double-si...
