Color: 7.5m Size: Dual Overview This electric solar panel cleaning brush combines an automatically rotating dual brush head with selectable dry and water cleaning modes for efficient maintenance of photovoltaic panels and other outdoor glass surfaces. It is designed to reduce manual effort while maintaining surface care. Key benefits Faster cleaning: Brush head rotation reaches up to 380 RPM, improving cleaning efficiency by 20 percent compared to standard solar cleaning brushes. Balanced rotation: Dual brush head rotation provides balanced force for consistent contact across the cleaning width. Versatile cleaning modes: Select dry or water mode to match surface conditions and soil types. Lightweight brush head: The brush head weighs 4 kg, lighter than similar products, which reduces operator fatigue. Broad coverage: Brush width up to 65 cm enables one operator to clean approximately 500 to 750 square meters per hour, depending on conditions. Specifications and materials Pole length options: 3.5M, 5.5M, and 7.5M extendable poles to reach different heights. Consider the pole weight and your work requirements when selecting a length. note: Pole and brush head are separately for convenience. Brush filaments: Dense nylon filaments with moderate hardness designed to clean effectively while minimizing the risk of scratching sensitive surfaces. Brush head weight: 4 kg. Cleaning width: up to 65 cm. Rotation speed: up to 380 RPM. Applications and use scenarios Solar farms and rooftop photovoltaic arrays: Routine cleaning to remove dust, bird droppings, and light residue to help maintain panel output. Mobile and recreational vehicles: Cleaning RV glass and windows while on the road or at a campsite. Commercial signage and billboards: Remove surface dirt and grime from store signs and outdoor advertising panels. Practical notes for buyers Select the pole length that matches maximum working height and consider the added weight when extended. The brush head and pole are sent separately to simplify packaging; assemble before use. Use the dry mode for light dust and the water mode for stuckon debris or grime. Regular, gentle cleaning with the nylon filaments helps maintain surface integrity over time. This cleaning tool is intended for outdoor maintenance of solar panels, glass surfaces, signs, and similar installations where an automatic rotating brush and extendable pole improve efficiency and ease of use.
