Large 50 L water tank
Fewer refills and fast liquid changes keep the drone working over large areas in a single operation.
Partdro Solar Cleaning Drone Series D50R
Photovoltaic Intelligent Cleaning,Built for solar plants.
The D50R pairs a 50 L water tank with full-process automated cleaning and route planning — dual RTK positioning, forward obstacle radar and standard high-pressure nozzles keep large PV arrays clean without sending workers onto the panels.

Why choose it
One platform for every PV cleaning job.
From ground-mounted plants to fishery-PV arrays, the D50R replaces manual high-altitude cleaning with an automated drone workflow.
Full-process automation
Cleaning and route planning run end-to-end: plan the mission once and the drone executes it autonomously.
Standard high-pressure nozzles
High-pressure jets reach panel gaps and stubborn stains, with a 0° pinpoint jet for the toughest dirt.
Integrated flight control
One operator flies and cleans from a single station, with custom integration for multiple flight platforms.
Dual RTK plus obstacle radar
Centimeter-level positioning and forward obstacle sensing keep every pass stable and safe over the array.
Replaces manual work at height
No scaffolding, no ropes, no workers on roofs — one pilot and one ground operator run the whole job.
Design highlights
Modular design, multi-scenario ready.
A modular cleaning platform that adapts to different PV sites — tank, booms and nozzles all swap to match the task at hand.
A
50 L water tank
Large single-fill capacity covers wide arrays, and the quick-change design makes refills fast.
B
Dual swing spray booms
Booms oscillate from 0° to 45°, washing large panel surfaces evenly in a single pass.
C
Multi-nozzle compatibility
Standard high-pressure nozzles for gaps and stubborn stains, plus a 0° pinpoint jet for stubborn spots.
Field results
5,500 m²
Cleaned per day in the Huizhou fishery-PV case
Figures from the 100,000 m² / 20 MW fishery-PV project: one pilot plus one ground operator finished in 18 days, cutting the schedule by more than 60%.
Area per sortie138 m²
Takeoffs per hour5
Manual cleaning rateBelow 900 m² per person-day
Project schedule18 days (30+ days manually)
Power generation gain12-15% after cleaning
Intelligence — Automated route planning
Full-process automation, from plan to clean.
The D50R plans cleaning routes on the ground station and flies them autonomously, covering every panel without blind spots.
01
Full-coverage route planning
Missions are planned per site and height, avoiding omissions and blind spots across the array.
02
RTK-precision flight
Dual RTK keeps position and attitude accurate for consistent, repeatable cleaning paths.
03
High automation
Routes planned on the ground station are executed automatically without real-time manual control.
04
Remote operation
The operator monitors and controls the drone from the ground, away from the cleaning zone.
Safety
Unmanned high-altitude operations, protected by dual RTK.
The D50R keeps workers on the ground while built-in sensors guard every flight over the array.
Replaces manual work at heightRemote operation eliminates the fall risks of rooftop and suspended-access cleaning work.
High-precision dual RTKBuilt-in dual RTK modules output centimeter-level positioning for accurate, reliable flight.
Intelligent obstacle avoidanceForward-looking radar senses obstacles in real time and maintains a safe operating distance.
Multi-scenario
Stable at height, flexible at every angle.
Modular mounts and multiple nozzle options let the D50R cover panel tops, bottoms and hard-to-reach angles.
↗
Stable high-altitude operation
Dual RTK and the perception-decision-execution loop keep washing stable at working height.
↔
Multi-module expansion
Tank, boom and nozzle modules can be configured for different cleaning tasks.
＋
Compatible with multiple nozzles
Standard high-pressure nozzles handle gaps and stubborn stains across panel types.
Wide-angle coverage
Spray booms swinging from 0° to 45° cover bottom and top surfaces in fewer passes.
Comparison of D50R and manual PV cleaning
The D50R cleans faster, safer and at lower cost.
| Partdro D50R | Manual PV cleaning | |
|---|---|---|
| Safety | Drone works at height while the crew stays on the ground | Workers clean rooftops and arrays in person |
| Efficiency | 5,500 m² per day with a 2-person crew | Below 900 m² per person-day with month-long projects |
| Cost | One equipment investment with low operating cost | Large recurring labor teams for every wash |
| Cleaning effect | 8-10 MPa high-pressure rinse removes stubborn stains | Panel gaps and stubborn dirt are hard to clean thoroughly |
| Schedule | 18 days for a 100,000 m² plant | More than one month for the same area |
| Power output | Generation increases 12-15% after cleaning | Soiling losses persist between manual washes |
Ground-mounted PV plants
Row-by-row cleaning for large utility-scale solar farms.
Commercial and industrial rooftops
Clean rooftop PV safely — no workers on the roof.
Fishery-PV plants
8-10 MPa water rinse tuned for panels over aquaculture ponds.
Residential and distributed PV
Compact sorties suit distributed and residential rooftop systems.
