Keep your photovoltaic panels operating near peak output with a purposebuilt solar panel cleaning kit. This system reduces the energy loss caused by dust and sticky deposits, lowers the need for manual altitude cleaning, and is designed for safe, singleperson operation. Key benefits Restores generation efficiency by removing dust and deposits that reduce panel output. Reduces labor, risk, and frequency of altitude manual cleaning through an extendable, waterfed, motorized brush system. Portable and lightweight design allows easy use by one person, including elderly users and women. Main features Power supply options AC adapter model: 110V or 220V with an 8 meter power cord for use near power outlets. Lithium battery DC model: 24V battery backpack for wireless operation and mobility. Telescopic pole lengths Three selectable pole lengths: 11 ft (3.5 m), 18 ft (5.5 m), and 24 ft (7.5 m). Choose the length that matches your installation height. Waterfed telescopic design allows onthefly adjustment to reach different panel heights. Cleaning performance Cleaning width up to 65 cm per pass. Single operator cleaning rate up to 500 to 750 cubic meters per hour as stated for the device. Watersaving spray system with typical consumption of about 1.5 to 3 liters per cubic meter. Oppositerotation dual brush heads provide balanced, speed brushing while the water spray removes dust and sticky dirt. Durable construction density reinforced aluminum alloy components offer hardness, rust resistance, and low weight for easy handling. Telescopic rods use carbon fiber or glass fiber depending on the model for durability and resistance to deformation. PE bristles for effective dust removal and extended service life. Ease of use Universal brush head design rotates to reach corners and tilted panels. Lightweight carry backpack available with the lithium battery model for easy transport. Multifunctional socket converter included for flexible connections.

Available brush lengths include options equivalent to 13.5 m, 15.5 m, and 17.5 m extensions to match different installations. Practical use scenarios Residential rooftop arrays: Clean domestic rooftop panels safely from the ground or a low roof level using the battery model for mobility. Commercial rooftops and carports: Use the extended pole and AC power option where power is available to cover broad roof areas without frequent battery swaps. Groundmounted solar farms: Combine the long reach pole and waterfed spray to maintain larger arrays with fewer staff and reduced downtime. Notes Choose the telescopic pole length that matches your installation before ordering. If you have questions during setup or use, contact the seller through the platform for assistance.
