Problems solved by technology

[0003] In some photovoltaic systems, the ventilation conditions around the photovoltaic modules are poor, and the angle between the photovoltaic modules and the ground is small, so a large amount of hot air gathers on the back of the photovoltaic modules, resulting in a sharp rise in the operating temperature of the photovoltaic modules
The increase in temperature will significantly reduce the energy conversion efficiency of photovoltaic modules, which will convert more solar energy into heat energy, thus creating a vicious circle, making the energy conversion efficiency of photovoltaic modules lower and lower

Abstract

The invention relates to a photovoltaic module, which comprises a photovoltaic module body and a heat dissipation fin, and is characterized in that the heat dissipation fin is provided with an attaching part and a bent heat dissipation part, the attaching part is attached to the back surface of the photovoltaic module body, and the bent heat dissipation part is bent away from the back surface of the photovoltaic module body. The heat dissipation fin can effectively prevent the temperature of the photovoltaic module from rising, so that the photovoltaic module works in a proper temperature range, and the photovoltaic module is ensured to have ideal energy conversion efficiency. Besides, the structure is simple, the installation is convenient, the heat can be dissipated for a long time almost without any maintenance, and the manufacturing, installation and later maintenance costs of the photovoltaic module are effectively reduced. The invention further relates to a manufacturing method of the photovoltaic module.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module production and manufacturing, in particular to a photovoltaic module and a manufacturing method thereof. Background technique [0002] Photovoltaic modules are a key component of photovoltaic systems, and the energy conversion efficiency of photovoltaic modules is an important factor that restricts the efficiency of the entire photovoltaic system. In order to ensure the absorption efficiency of photovoltaic modules to sunlight, the angle between photovoltaic modules and the ground is set to be small. However, during the energy conversion process of photovoltaic modules, a large part of solar energy is not converted into electrical energy, but in the form of thermal energy. released into the environment around the PV module. [0003] In some photovoltaic systems, the ventilation conditions around the photovoltaic modules are poor, and the angle between the photovoltaic modules and the ...
