Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panels, and in particular relates to a photovoltaic panel and a supporting device thereof. Background Art

[0002] Photovoltaic panels (also known as solar panels) are devices that convert solar energy into electrical energy through the photovoltaic effect. The photovoltaic effect refers to the fact that in specific materials (such as silicon), when sunlight shines on these materials, electrons are excited and generate current, thereby generating electricity. Photovoltaic panels are widely used in solar power generation systems and can provide clean energy for homes, industries, and commercial buildings, helping to reduce dependence on traditional fossil fuels.

[0003] The working principle of photovoltaic panels is based on the photovoltaic effect. In short, when photons (light particles) in sunlight hit the semiconductor material (such as silicon) on the photovoltaic panel, they excite the electrons in it and cause them to break away from the atoms, forming an electron flow. These free electrons flow through the circuit, generating current, thereby generating electrical energy. As an important form of renewable energy, photovoltaic panels have broad application prospects and huge market potential. With the continuous advancement of technology and the reduction of costs, photovoltaic panels will become an indispensable part of the global energy structure, helping to achieve a low-carbon economy and sustainable development goals.

[0004] The photovoltaic panel support system (also known as photovoltaic bracket or photovoltaic support structure) is an important component of the installation of photovoltaic panels. Its function is to support and fix the solar panels, while ensuring that the photovoltaic panels can work stably and reliably under various environmental conditions. The support system must not only ensure the safety of the photovoltaic panels, but also maximize their light reception angle and improve the system's power generation efficiency.

[0005] The prior art discloses several invention patents in the field of photovoltaic panels. Patent application number CN202310464621.4 discloses a photovoltaic power generation system and its solar photovoltaic panel support device. Patent application number CN202210040375.5 discloses a novel photovoltaic and thermal integrated utilization device and its manufacturing method.

[0006] When the above two existing technologies are installed and used outdoors, weeds will grow on the ground under the photovoltaic panels. Since the existing technologies are not convenient for handling the growing weeds, excessive weed growth may cause mechanical damage to the brackets and photovoltaic panels, especially in areas with strong winds, which may accelerate the corrosion of the brackets. Weeds accumulated over a long period of time may block part of the sunlight from the photovoltaic panels. In particular, taller weeds will affect the light under the photovoltaic panels and reduce the power generation efficiency of the photovoltaic panels. Even if the weeds do not completely block the photovoltaic panels, they will absorb part of the sunlight or create shadows, causing uneven lighting on the photovoltaic panels and affecting power generation.

[0007] Based on this, the present invention designs a photovoltaic panel and a supporting device thereof to solve the above problems. Summary of the Invention
