Description

Technical Field

[0001] The invention relates to the field of photovoltaic cleaning, and in particular to photovoltaic cleaning equipment with convenient replacement of cleaning components. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Whether it is used independently or connected to the grid, the photovoltaic power generation system is mainly composed of three parts: solar panels (assemblies), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment is extremely refined, reliable, stable, long-life, and easy to install and maintain. The solar photovoltaic power generation system consists of solar cell groups, solar controllers, and batteries (groups). Solar panels are the core part of the solar power generation system and the most valuable part of the solar power generation system. Its function is to convert the sun's radiation capacity into electrical energy, or send it to the battery for storage, or drive the load to work.

[0003] Since solar panels are arranged outdoors, long-term use will cause dust to adhere to their surface, and the solar panels need to be cleaned regularly.
