The ZK-C50R cleaning drone features a modular design, equipped with a 50L water tank and a newly designed high-pressure water spray system that supports side-by-side cleaning with multiple nozzles. With three different high-pressure nozzle designs that can be freely switched to meet diverse cleaning needs, it provides the industry with a convenient, efficient, and versatile aerial high-pressure cleaning solution suitable for multiple scenarios. It has been widely used in high-altitude cleaning applications such as large-scale ground-mounted solar power plant panels, commercial and industrial rooftop solar systems, and residential rooftop solar systems.
The ZK-C50R is compatible with a variety of universal cleaners. Its dual RTK and dual radar configuration enables centimeter-level positioning accuracy. The front obstacle-avoidance radar and downward terrain-following radar provide real-time detection of surrounding obstacles. With an integrated flight control system, it can be operated by a single person and supports customized integration with a wide range of flight platforms. By combining cleaning functions with flight path planning, it enables aerial cleaning operations and end-to-end automated control, ensuring efficient and seamless workflow.
By integrating drone flight control technology, a cleaning system, and intelligent path planning, the ZK-C50R cleaning UAV allows users to preset flight parameters. The drone can then autonomously take off, execute cleaning tasks, and return to recharge and refill water, truly achieving fully automated PV cleaning operations. Operating for 8 hours per day, a single unit can clean 690 square meters per hour, totaling up to 5,520 square meters of PV modules daily.

Application Scenarios





Case Study
Providing innovative, efficient, and safe solutions for cleaning floating solar panels

in Huizhou (2024.5.11)
Due to high temperatures and humidity, algae and other biological growth accumulate on the surface of the solar panels. Since the panels are installed above bodies of water such as fish ponds, manual cleaning must be performed on the water's surface, where conditions are complex and pose a risk of drowning.
Drone high-altitude cleaning:No need for personnel to work at heights, eliminating satety risks of high-altitude operations.
Cost savings: Greatly cuts labor and maintenance costs, saving substantial funds long-term.
Safe & stable operation: Dual RTK ensures real-time cm-level positioning for reliability.
Cleaning efficiency: 690mi/h rate shortens large-scale PV cleaning time and boosts productivity.
The drone-based solution for cleaning floating solar panels offers significant advantages:
By leveraging the efficiency and flexibility of drones, it can quickly cover large areas of solar panels without the need for manual work on the water, thereby reducing safety risks. Precise cleaning ensures the power generation efficiency of the solar panels and saves on labor costs.
