In the past, the vast majority of PV power plants relied on manual cleaning to complete O&M work，but as installed PV capacity continues to increase、labor costs continue to rise，and the risks of working at height on rooftop PV systems remain high，the shortcomings of traditional manual cleaning have been fully exposed，and intelligent unmanned cleaning equipment is gradually becoming standard in the PV O&M industry。

Four Core Hidden Risks of Manual PV Cleaning

1. High safety risks for work at height：PV operation spaces on sloped roofs and high-rise rooftops are narrow，and manual climbing for cleaning is highly prone to fall accidents，making safety protection difficult。

2. Easy damage to PV modules：Personnel directly step on PV panel surfaces，which can easily cause hidden cracks in modules and glass breakage，directly resulting in PV panel scrapping and high losses。

3. Low cleaning efficiency：The cleaning area per person per day is limited，and for large ground-mounted power plants and continuous rooftop power plants，manual cleaning cycles are long and cannot meet high-frequency O&M requirements。

4. Labor costs continue to rise：Difficulty in recruitment and high labor costs have become the norm in the industry，and the total cost of long-term manual O&M is far higher than the investment in automated cleaning equipment。

Core Advantages of Intelligent PV Cleaning Equipment

In response to all pain points of manual cleaning，our full range of PV cleaning equipment has been comprehensively optimized：equipped with ultrasonic anti-fall protection and multi-directional anti-collision sensors，suitable for various sloped roofs；using dedicated flexible brushes，which do not scratch PV glass or anti-reflective coating throughout the process；supporting remote control and unmanned autonomous operation，with no need for personnel to climb to heights during the entire process；one device can replace multiple workers，significantly saving O&M costs over the long term。

Safety、efficiency、and cost reduction are the core demands of PV O&M。Saying goodbye to high-risk manual cleaning and choosing intelligent automated cleaning equipment is not only a way to avoid safety risks，but also an inevitable choice for refined power plant O&M，cost reduction，and efficiency improvement。
