Solar panel cleaning rotating brush — Size 5.5m, Color Dual Key benefits Efficient cleaning with dual rotating brush heads that operate at 300 rpm in forward and reverse. torque and wide brush coverage remove dust, bird droppings, and other deposits for faster cleaning of photovoltaic surfaces. Flexible reach and stable handling via an industrialgrade thickened aluminum alloy telescopic rod. The 5.5 m configuration provides extended access while a secure locking mechanism and Ttype damping rotation keep the brush angle stable on roofs and uneven surfaces. Dual power modes for onsite versatility. Use the 24 V lithium battery pack for mobile, offgrid cleaning or connect to 110 V / 220 V mains for prolonged operations. Waterefficient threehole spray design that brushes and flushes simultaneously, using about 1.5 to 3 liters per square meter to limit water use during largescale cleaning. Durable construction and components for repeated professional use: nylon wire brushes, DC motor drive, and a robust drive kit set. Main specifications Material: nylon wire Power supply options: mains version 110 V or 220 V; lithium battery 24 V / 26 Ah Battery life (lithium): 4 to 5 hours Dual power capability: lithium battery plus 110 V / 220 V mains Cleaning diameter: 70 cm Drive: DC motor Speed: 300 rpm Torque: 5 kg/cm2 Maximum power: 240 W Operating voltage: 24 V Telescopic rod lengths available: 3.5 m, 5.5 m, 7.5 m; delivered in the 5.5 m configuration Collapsed lengths after shortening: 1.4 m, 1.8 m, 2.1 m Rod wall thickness: 1 mm Maximum pipe diameter for assembly: 40 mm Water consumption estimate: approximately 1.5 to 3 liters per square meter; approximately 9 to 15 tons per 1 MW as a planning reference Threehole water spray with water control valve for tap water connection Performance and design features Dual brush heads rotate in both directions to dislodge stubborn stains while minimizing repeated passes. Ttype damping rotation kit automatically adjusts brush head angle for cleaning on sloping roofs, piles, and uneven surfaces. Drive motor kit provides stable rotation at 300 rpm with sufficient torque for efficient debris removal. Telescopic rod uses a locking structure to prevent bending and to allow flexible length adjustment for different cleaning heights and scenarios. Lightweight aluminum construction and compact collapsed size for easier transport and storage. Low water consumption and integrated water control make the system suitable for largearea cleaning without excessive water use. Included items (Dualpurpose version, Color Dual, Size 5.5 m) Telescopic rod x 1 9 m water and electricity line x 1 10 m extended water and electricity line x 1 Photovoltaic special brush x 2 Drive motor kit x 2 Ttype damping rotation jump kit x 1 Electric spring wire x 1 Lithium battery pack x 1 Lithium battery charger x 1 Backpack x 1 Power converter x 1 Accessory package x 1 Typical applications Groundmounted solar farms and photovoltaic power plants where regular cleaning preserves panel output and reduces manual labor. Commercial and industrial rooftops, including sloped and roofs, where the adjustable rod and damping rotation improve reach and brush angle control. Remote or offgrid installations and facilities where batterypowered mobile cleaning is required, such as mountain sites or areas without convenient mains access.
