Photovoltaic assembly applied to building

Abstract

The invention relates to the technical field of photovoltaic assemblies, in particular to a photovoltaic assembly applied to a building. The photovoltaic assembly comprises a mounting frame, an innerglass group and an outer glass group. The inner glass group is installed at one side, near the indoor, of the mounting frame; the outer glass group is installed on the side, away from the indoor space, of the mounting frame; and a solar battery group is arranged between the inner glass group and the outer glass group. The inner glass group includes a piece of inner fixed glass and a piece of innermovable glass; the outer glass group includes a piece of outer fixed glass and a piece of outer movable glass; the inner fixed glass and the outer fixed glass are fixedly installed at the mounting frame; the inner fixed glass, the outer fixed glass, and the mounting frame form a sealed mounting cavity; the mounting cavity is divided into an inner cavity, a photovoltaic cavity, and an outer cavityby the inner movable glass and the outer movable glass. According to the photovoltaic assembly having the heat insulation function, the energy consumption needed by indoor temperature regulation is reduced; and a problem of glass breakage caused by the unstable air pressure is solved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a photovoltaic component applied to buildings. Background technique [0002] At present, in the solar photovoltaic cell module industry, there are no more than two types of photovoltaic modules for building integrated photovoltaics (BIPV): one is an ordinary dual-wave battery module, and the other is a hollow photovoltaic module. [0003] Ordinary dual-wave battery modules are also called the first generation of BIPV battery modules, which use tempered glass instead of the back protection material of photovoltaic modules and are packaged with adhesive film. This kind of BIPV battery module has undoubtedly broken the technical barriers of the photovoltaic industry and the construction industry, but there are also many drawbacks that directly restrict the development of BIPV battery modules. The first is heat insulation capacity: there are three kinds of energy tra...

AI Technical Summary

Problems solved by technology

However, since the photovoltaic module generates a lot of heat during the power generation process, the heat cannot be discharged due to the hollow layer of the hollow photovoltaic module. High will directly affect the power generation efficiency of photovoltaic cells

Therefore, the utilization and application of hollow photovoltaic modules are quite controversial
