[0002] The background of photovoltaic maintenance technology refers to a series of inspection, cleaning, testing and maintenance measures taken to ensure the continuous and efficient power generation of photovoltaic power plants. Its core is to eliminate hidden dangers such as dust obstruction, hot spot effect, and wiring faults through regular maintenance, so as to maintain the normal operation of key equipment such as modules, inverters, and brackets, slow down the degradation of system performance, and ensure power generation and safety.

[0003] Traditional photovoltaic panel cleaning devices are mostly used independently or in small areas, making it difficult to efficiently adapt to large-scale, continuously arranged photovoltaic arrays. This results in time-consuming and labor-intensive cleaning work. In addition, some cleaning devices place their cleaning components directly on the photovoltaic panel surface when not in use, blocking sunlight for a long time and reducing the effective light-illuminated area, which may directly affect the power plant's power generation efficiency.

[0004] In view of this, we propose a photovoltaic panel cleaning device. Utility Model Content
