With the continuous expansion of global PV installed capacity，the number of ground-mounted power stations and rooftop distributed PV systems is increasing year by year，while traditional manual cleaning methods involve high costs，significant risks for high-altitude operations，and incomplete cleaning coverage，making it difficult to meet the needs of large-scale operation and maintenance。

The global energy transition continues to accelerate，and photovoltaics, as a core clean energy sector, maintains long-term growth momentum。

Photovoltaic power stations operate outdoors for long periods，and the panel surfaces are highly prone to accumulating dust、bird droppings、mud and sand、fallen leaves and other debris。

The shortcomings of traditional manual cleaning have been fully exposed, and intelligent unmanned cleaning equipment is gradually becoming standard in the photovoltaic O&M industry.
