Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, and in particular to a wind-resistant device for a photovoltaic panel. Background Art

[0002] Photovoltaic power generation is a technology that converts light energy directly into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. Photovoltaic panels are often needed in the process of photovoltaic power generation.
