[0001] The invention relates to the technical field of solar photovoltaic technology, in particular to a solar photovoltaic panel with snow removal function. Background Art

[0002] Solar photovoltaic panels, as a clean and renewable energy device, are widely used in various fields. However, in cold and snowy areas, photovoltaic panels are easily covered with snow in winter, which not only reduces the power generation efficiency of photovoltaic panels, but also may cause damage to the structure of photovoltaic panels. In the prior art, although some photovoltaic panels have snow removal functions, most of them use mechanical methods to remove snow. This method not only has high energy consumption, but also easily damages the surface of photovoltaic panels and reduces their service life. In addition, mechanical snow removal methods are less efficient in heavy snow conditions, and it is difficult to remove snow in time, which seriously affects the normal operation of photovoltaic panels.

[0003] In order to solve the above problems, some studies have tried to melt the snow by installing heating components under the photovoltaic panels to achieve the purpose of snow removal. However, the design and installation of such heating components are often complicated, and the heating efficiency is not high, which easily leads to energy waste. At the same time, higher requirements are also placed on the temperature control of the photovoltaic panels themselves to avoid damage to the photovoltaic panels due to overheating.

[0004] Therefore, there is an urgent need to provide a solar photovoltaic panel with a snow removal function to improve snow removal efficiency, reduce energy consumption, and protect the photovoltaic panel from damage to ensure its long-term stable operation. Summary of the invention
