Design and application value
A cleaning solution combines aircraft, cleaning payload, water supply, mission planning and site organization. Suitable paths and spray coverage can reduce repeated passes, but results depend on soiling, surface material, water quality and settings. Define the cleaning objective before matching equipment and process.
Choosing the right configuration
Survey array or façade dimensions, materials, joints and obstacles; confirm power, water and exclusion areas. Check permitted cleaning methods for PV modules. For façades, assess nozzle reaction, hose mass and corners. Validate reference productivity on a representative trial area.
Installation and integration
Begin with a low-risk trial area and verify water delivery, hover stability, standoff and coverage before adjusting path and speed. Settings must suit the surface or module manufacturer’s requirements. Define withdrawal routes and ground-team roles for water loss, power loss or changing wind.
Operation and maintenance
Record before-and-after images, residual soil and surface condition for acceptance. Track flight, refilling, relocation and setup separately. After work, flush filters and nozzles, inspect hoses and electrical connections, and dry as required. Evaluate productivity using total working time, not spray time alone.
