BIPV framed hollow curtain wall photovoltaic assembly structure

Abstract

A BIPV framed hollow curtain wall photovoltaic module structure disclosed by the present invention comprises a photoelectric module, the circumferential outer edge of the photoelectric module is provided with frame profiles which are connected end to end, the photoelectric module comprises a double-sided double-glass module and inner-layer glass which are parallel and have a gap, and the photoelectric module and the frame profiles at the circumferential outer edge define a negative pressure cavity; the frame section bar is provided with an assembly positioning groove and an inner layer positioning groove, and the frame section bar is further provided with an assembly channel communicated with the negative pressure cavity. According to the BIPV framed hollow curtain wall photovoltaic assembly structure, protection of the double-sided double-glass assembly is enhanced through the inner-layer glass, water vapor is prevented from entering the double-sided double-glass assembly, the service life of the device is prolonged, the loading capacity of the device is enhanced, rapid assembly between the assemblies is facilitated through the assembly channels, meanwhile, vacuum is conveniently formed in the negative pressure cavity, therefore, the light energy loss of the light is reduced, the power generation efficiency is improved, and in addition, the heat insulation, heat preservation and sound insulation effects are enhanced.

Description

technical field [0001] The invention relates to a photovoltaic module structure, in particular to a BIPV framed hollow curtain wall photovoltaic module structure. Background technique [0002] With the improvement of the conversion efficiency of photovoltaic modules into the accelerator, the double-sided double-glazed module of high-efficiency products with low energy consumption cost came into being. As the name suggests, a double-sided module is a module that can generate electricity on both sides. When the sun shines on the front of the double-sided module, part of the light will be reflected by the surrounding environment to the back of the double-sided module, and this part of the light can be absorbed by the battery, thereby reducing the cost of the double-sided module. Compared with traditional monocrystalline cells, bifacial photovoltaic modules can generate electricity under the condition of direct sunlight on the front and reflection of sunlight on the back, thereb...

Problems solved by technology

[0004] However, during the installation of the above-mentioned double-sided double-glass photovoltaic modules, the adjacent frames need to be processed and connected by riveting points, resulting in troublesome splicing; and the loadability of the device is poor, and it is easy to burst and damage due to collisions. Not only that, during the operation of the device, Moisture can easily enter the inside of the module, which reduces the efficiency of photovoltaic power generation and shortens the service life of the module; in addition, during the power generation process of the photovoltaic module, the reflected sunlight is easily absorbed by dust in the air, before it hits the back of the photovoltaic module. Impurities such as water vapor consume light energy, causing light energy to be lost before the light hits the back of the photovoltaic module, and there is still room for improvement in the power generation efficiency of photovoltaic modules
