Novel photovoltaic component for building

Abstract

The invention relates to a novel photovoltaic component for a building. The novel photovoltaic component for the building comprises a photovoltaic module, connectors, a junction box, a frame, filling material and a component back plate. The junction box, the connector part stretching into the frame, a metal back plate of the photovoltaic module, the frame and the component back plate are bonded to form an integral module through the filling material. Due to the novel photovoltaic component, the heat preservation performance of the building is achieved, the problem of heat dissipation of a heat generating device in the junction box of the photovoltaic module is solved, influences caused by the hot spot effect are reduced, and meanwhile the insulation problem brought by using the metal back plate is solved. Besides, due to the standard modular structure design, the novel photovoltaic component for the building is convenient to install and maintain, and the integration of the photovoltaic building is achieved. A honeycomb core layer and a honeycomb pore plate are omitted in the structure, one the premise that the structural strength is guaranteed, material cost is reduced, and the technology is relatively simple. Because the L-type connector and the U-type connector can be used in cooperation, the novel photovoltaic component for the building can be detached independently and is convenient to maintain.

Description

technical field [0001] The invention relates to an industrial component of building exterior protection with photovoltaic power generation function, which is used for solar power generation and can directly replace building roof or wall materials. [0002] Background technique [0003] Chinese patent 201848478U discloses a building photovoltaic component module, including a photovoltaic module, a connector, a junction box and a frame. The photovoltaic module is composed of glass, adhesive layer, solar cells and a metal back plate. The honeycomb core layer, the honeycomb porous plate, the thermal insulation layer and the member backboard filled with foaming materials; the honeycomb core layer is distributed on the honeycomb porous plate as a whole; the honeycomb core layer, the honeycomb porous plate and the thermal insulation layer are filled The foam material is bonded and cured to form an overall structure, wherein the honeycomb core layer is also bonded to the metal bac...

AI Technical Summary

Problems solved by technology

The module structure of the above-mentioned patent has the following problems in practical application: First, after adding the honeycomb core layer and the honeycomb hole plate in the module, it not only increases the material cost and processing cost, but also increases the complexity of the processing technology ; Second, due to the unreasonable structure of the connector, the electrical connection and structural installation must be completed at the same time, which increases the difficulty of construction and takes time. The other modules can only be disassembled after all other modules are removed, which is inconvenient for maintenance; third, in the actual installation process of building photovoltaic component modules, the distance between building photovoltaic component modules cannot be controlled consistently, which requires the design of the sealing groove on the module to allow Ability to properly install seals under conditions of inconsistent module spacing

That is to say, under the premise of not affecting the sun blocking function and aesthetics of the sealing strip, the sealing strip can be installed smoothly, and the tolerance in the installation process can be released, but the structure in the prior art cannot do this
