Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panel protection, and in particular to a protective device for solar photovoltaic panels. Background Art

[0002] As the power of new energy sources gradually expands and environmental awareness gradually increases, solar energy has become the focus of today's society. Existing solar panels require an environment with sufficient light, so they are generally set up in a large area in a relatively open space. However, due to the influence of the open space, the airflow gradually becomes stronger due to the small ground resistance. When passing through the solar panels, the strong airflow can easily overturn the solar panels, causing damage to the equipment.

[0003] At the same time, dust on the ground surface continuously passes through the surface of the solar panels with the air flow. Long-term wind and sand invasion causes a large amount of dust to accumulate on the surface of the solar panels, which gradually reduces the efficiency of the solar panels in receiving light, resulting in reduced working efficiency of the solar panels. In addition, the existing solar photovoltaic panels lack protection functions, and in severe weather, the solar photovoltaic panels are easily damaged by the outside world.
