Non-standard Gantry Crane Cleaning Equipment for Ground Solar Projects

The cleaning machine supports two working modes for option: operator remote control and unmanned self-operation. You can choose to use a remote to have instant control over the moving gantry crane and cleaning components, or freely switch to the autonomous mode, letting it to travel long distance along the continuous solar rows with photovoltaic cleaning works done automatically.

To suit the latter purpose, we have developed smart control system, advanced positioning and navigation system and wireless communication system. So, the mobile gantry crane solar cleaner can perform auto-driving to implement automated solar cleaning cycles without worrying about complex vehicle manipulation and route planning. Rather, the operator can get real time monitoring over the onsite path tracking and equipment status data from cloud management backend.

In terms of land passability, our four-wheel-drive mechanical configuration delivers strong motion power during full-load cleaning operations, with climbing gradeability up to 10 degrees and 100mm obstacle crossing height.

What’s more, a resilient battery is employed as the power source lasting around 12 hours, which reliably supports the utility scale solar cleaning operations. In order to further enhance coverage requirements, we offer fuel generator for your option, achieving extended driving range.

Efficient one-pass cleaning is fulfilled by the compound cleaning arrangement, combining dual roller brush sweeping, dust vacuuming and water washing. The panel friendly brushes with soft bristles, counter-rotate at high speed to provide effective dust dislodging force; In the meantime, the vacuum cleaner starts collecting dust through direct suction within the enclosed space between the two roller brushes, to prevent contamination of reentrainment. In cases of heavily stubborn fouling formed on certain PV panels, you can partially use water-fed wet cleaning method for thorough dirt removal, suitable for arid regions.

To ensuring satisfactory cleaning performance and damage free operation, the intelligent solar cleaning equipment adopts a self-adaptation linkage cleaning architecture, dynamically adjusting the brush angle, position and contact pressure according to different terrain condition, PV panel installation tilts, solar array layouts as well as the mounting structure heights.

When equipped with visible light camera & infrared thermal imaging camera, the cleaning gantry system can simultaneously carry out PV module cleaning and inspecting. Powered by artificial intelligence technology and onboard computing modules, on-patrol photovoltaic inspection realizes effective recognition of abnormities, defects, shading on the solar panel surfaces, supporting automatic generation of health inspection report.
