Solar photovoltaic module frame

Abstract

The invention discloses a solar photovoltaic module frame capable of stabilizing the photoelectric conversion efficiency of a solar photovoltaic module, wherein the inner side of the frame is equipped with a bayonet for installing the solar photovoltaic module; the backside of the frame is an installation side; and an installation cavity is arranged between the installation side and the bayonet. The solar photovoltaic module frame is characterized in that at least one ventilating hole is arranged on the sunward side of the frame, and the ventilating hole is communicated with the installation cavity. When the solar photovoltaic module frame is used, heat of the backside of the solar photovoltaic module can be smoothly discharged through the ventilating hole without causing continuous temperature rise of the solar photovoltaic module so as to guarantee the photoelectric conversion efficiency.

Description

technical field [0001] The present invention relates to a frame of a solar photovoltaic module. Background technique [0002] Solar photovoltaic modules usually include solar cell modules and frames. Solar cell modules are generally composed of five layers of tempered glass, EVA layer, solar cell, EVA layer and back sheet, which are combined into one by a laminator; in order to improve solar cells The strength of the module is convenient for transportation and installation. Usually, the solar cell module is encapsulated with an aluminum frame around it. The aluminum frame is generally composed of several profiles fixed and connected. For example, a rectangular aluminum frame is composed of four profiles fixed and connected. The inner side of the frame is provided with a bayonet for installing the solar cell assembly, the frame is provided with a reinforcing rib, the back side of the frame is the installation surface, and the solar photovoltaic module is installed on the buil...

Problems solved by technology

[0003] During the use of solar cell modules, they will generate heat due to sunlight, and a certain amount of heat will be generated inside, which will increase the temperature of the cells and reduce the photoelectric conversion efficiency; large-scale photovoltaic power generation such as building walls or photovoltaic curtain walls In the system, especially the photovoltaic power generation system combined with the building, the solar photovoltaic modules are mostly arranged side by side, and they are closely connected to each other; and because the installation cavity of the frame and the sunny side of the frame are isolated from each other, resulting in the back of the solar cell module The heat cannot be dissipated smoothly, resulting in the continuous rise of the temperature of the components, which greatly reduces the photoelectric conversion efficiency of photovoltaic components and photovoltaic power generation systems
