From November 19 to 21, 2025, Qingdao Rhino Stone Intelligent Technology Co., Ltd. (hereinafter referred to as “Rhino Stone Tech”) made a remarkable appearance at the SEWK Expo in Osaka, Japan, presenting two flagship products—the RHINO700-EC6 Solar Panel Cleaning Robot and the EH2 Dual-Disc Solar Cleaning Brush. With photovoltaic intelligent cleaning solutions tailored to diverse application scenarios, Rhino Stone Tech demonstrated the strength of Chinese intelligent manufacturing. Thanks to the core product advantages of being easy to use, highly practical, and exceptionally durable, the showcased solutions became a focal point of the exhibition, attracting strong interest and widespread recognition from both domestic and international visitors.
At the expo, Rhino Stone Tech addressed key operational and maintenance challenges in the global PV cleaning sector by delivering precise and scenario-adapted intelligent solutions. Among them, the RHINO700-EC6 Solar Panel Cleaning Robot stood out as one of the most eye-catching products, owing to its innovative design and intelligent core technologies. Featuring a lightweight overall structure and front-and-rear dual adaptive floating roller brushes, the robot achieves a maximum cleaning width of up to 1.3 meters, significantly expanding coverage and greatly improving operational efficiency compared with traditional cleaning equipment. In addition, its intelligent anti-fall protection system accurately identifies panel boundaries to effectively mitigate fall risks.
Complementing the RHINO700-EC6, the EH2 Dual-Disc Solar Cleaning Brush won strong favor among small and medium-sized PV power station operators due to its unique structural design and outstanding durability. Its innovative five-petal brush head, powered by a dual brushless motor drive system, enables high-frequency and rapid dirt removal, markedly enhancing cleaning efficiency. The brush is also equipped with a high-performance carbon fiber pole that offers excellent anti-static properties and corrosion resistance—perfectly reflecting Rhino Stone’s product philosophy of ease of use, practicality, and durability. After hands-on experience, on-site visitors commented: “The RHINO700 series precisely meets the cleaning needs of large-scale photovoltaic power plants, effectively reduces operation and maintenance costs, and holds strong market application value.”
Throughout the exhibition, photovoltaic industry professionals, distributors, and end users from Japan, Thailand, Malaysia, and other countries and regions stopped by the booth for in-depth consultations. Industry representatives also engaged in extensive discussions on key topics such as PV cleaning technology upgrades, scenario-based application strategies, and future industry trends—jointly contributing momentum toward technological innovation and industrial upgrading in the global PV cleaning sector.
Rhino Stone Tech’s participation in the Osaka SEWK Expo marks an important step in its overseas market expansion strategy. Leveraging the exhibition platform, the company not only showcased its independently developed core technologies and high-quality products, but also gained valuable insights into demand pain points and development trends across Asian and global photovoltaic markets. These insights will serve as a solid foundation for future product iteration and strategic market deployment.
Looking ahead, Rhino Stone Tech will take this exhibition as a new starting point, continuing to place technological innovation at the core of its development strategy. By developing intelligent cleaning equipment tailored to the diverse needs of global markets, the company is committed to contributing value and strength toward the realization of worldwide low-carbon energy transition goals.
