Photovoltaic panels lose significant output when covered in dust and grime. Manual wiping is slow, labor intensive, and hard to do on roofs or over sheds. This electric solar panel cleaning brush is designed to remove stubborn dirt efficiently, increase cleaning coverage, and reduce manpower requirements. Key benefits Increased cleaning efficiency: 60 cm cleaning width and a 150 to 300 rpm rotating brush head cover more area per pass and can raise cleaning productivity by up to 80 percent compared with manual wiping. Two power options: choose mains version for continuous operation or lithium battery version for cordless mobility. Lithium battery specification 25V 26Ah provides about 6 to 8 hours of run time per charge. Flexible reach: three telescopic pole options adapt to different installations and enable near zerodeadangle cleaning on roofs, carports, and other hardtoreach places. A locking mechanism secures the chosen length. Two cleaning modes: dry brushing for quick debris removal and water washing for deeper cleaning to remove stubborn stains. Durable, lightweight construction: aluminum alloy telescopic rod and nylon brush filaments balance strength and ease of handling.

Solar Cleaning Brush — lithium battery version Water and electricity parallel pipe Universal plug Mini water pump Power converter 10 m yellow water pipe Lithium battery charger Lithium battery (25V 26Ah) Lithium battery backpack Use scenarios Residential rooftop solar arrays: reach panels installed on sloped roofs without climbing onto the roof, perform dry or wet cleaning to restore panel surface clarity. Commercial or utility installations and carport arrays: reduce labor time and extend cleaning coverage on long rows of panels using the extended telescopic poles. Hardtoaccess structures such as pergolas, sheds, or mounted awnings: adjust pole length and use the cordless lithium version to clean panels over obstacles. Operation and selection tips Choose the telescopic pole length that fits the mounting height and access conditions for safe and effective cleaning. Use dry mode for routine dust removal and water washing for sticky residues or heavy soiling. Verify the operating temperature range (10 to 40 C) for outdoor conditions before use. For continuous long sessions with reliable mains power, use the power converter version. For locations without convenient power access or for mobile cleaning, use the lithium battery version and carry the battery in the provided backpack for easier handling. This tool is built for practical, efficient solar panel maintenance and supports both fixedpower and portable workflows while providing adaptable reach and reliable cleaning performance.
