Electric photovoltaic cleaning roller brush machine designed for efficient, largescale solar panel cleaning where grid power is not available. Key benefits Fast, consistent cleaning: 350 rpm brushless motor delivers stable speed operation for thorough cleaning across large arrays. Wide coverage and productivity: Widened brush cleans up to 100 cm in a single pass. One operator can clean about 500 to 750 square meters per hour and can clean 3500 to 5000 m3 in an eight hour shift. Water efficient: Water consumption approximately 1.5 to 3 L/m3, helping reduce water use during wet cleaning. Panelsafe construction: Imported density nylon brushes are handwoven into panels so fibers will not shed and will not damage photovoltaic panels. Lightweight, adjustable reach: 50 mm diameter ultralight carbon fiber telescopic rod with a lock structure allows easy length adjustment. Angleadjustable head ensures good contact with panel surfaces. Flexible cleaning modes: Choose dry mode for quick decontamination or wet mode for deeper cleaning. Using both modes together provides flexible, efficient cleaning while minimizing water use and reducing soiling that can affect panel output. Designed for offgrid commercial use: Built for distributed factory roofs, large power plants, mountain solar power stations, and other commercial environments without onsite electricity. Function, materials, and performance Motor: Brushless, 350 rpm for speed operation. Brush width: Up to 100 cm for singlepass cleaning. Rod: 50 mm diameter carbon fiber telescopic rod, ultralight with locking mechanism for secure length setting. Brush material: Imported nylon, density, handwoven to prevent fiber loss and protect panel surfaces. Water use: Approximately 1.5 to 3 L per m3 during wet cleaning. Practical use scenarios Distributed factory roofs: One technician can rapidly clean long roof runs and large rooftop arrays where running power lines is impractical. Utilityscale solar farms and power plants: Suitable for largearea maintenance teams needing consistent, throughput cleaning on arrays in remote or mountainous locations. Remote or offgrid installations: Effective for mountain solar power stations and other sites without reliable grid access, where portability and efficiency are essential. What this product solves Reduces manual labor and time required to keep large solar arrays clean. Minimizes water use during wet cleaning while allowing thorough removal of dust and deposits. Protects panel surfaces with soft, durable brush material and adjustable angle control for uniform contact across arrays.
