Description

Technical Field

[0001] The invention relates to the field of photovoltaic power generation energy-saving wall panels, and in particular to an intelligent photovoltaic power generation energy-saving wall panel for buildings. Background Art

[0002] Smart photovoltaic energy-saving wall panels are an innovative building material that combines photovoltaic power generation technology and building energy conservation. This type of wall panel can not only effectively generate photovoltaic power, but also play a role in heat insulation and heat insulation in buildings, reducing energy consumption. The key feature of smart photovoltaic energy-saving wall panels is that the photovoltaic components (photovoltaic panels) embedded in the wall panels can use sunlight to convert into electrical energy, provide renewable energy for buildings, and reduce dependence on traditional electricity; smart photovoltaic energy-saving wall panels are often used in residential buildings, commercial buildings, industrial buildings, and public buildings. Smart photovoltaic wall panels can be used as exterior wall materials to provide renewable energy and reduce electricity bills; when the existing smart photovoltaic energy-saving wall panels are in use, the photovoltaic panels will generate heat during the power generation process. This is because photovoltaic cells will generate a certain amount of heat in the process of directly converting solar radiation energy into electrical energy. This heat is due to the energy consumption caused by the movement of electrons inside the photovoltaic cells, and part of the energy is dissipated in the form of heat. However, when the weather is hot, the hot weather plus the heat generated by the photovoltaic panels will cause the temperature to rise, and excessive temperature will cause changes in the current and voltage characteristics, thereby reducing the output power of the photovoltaic panels, and high temperature may accelerate the aging of photovoltaic materials and shorten their service life. For this reason, heat dissipation mechanisms are often used on existing intelligent photovoltaic power generation energy-saving wall panels to accelerate heat dissipation. However, the existing heat dissipation mechanisms accelerate the flow of air, so that the heat on the surface of the photovoltaic panels is faster to diffuse into the air. Although this can dissipate heat, it will waste a lot of heat resources. For this reason, we propose a smart photovoltaic power generation energy-saving wall panel for construction.
