AS-50 Solar Panel Cleaning Drone
AS-50 Solar Panel Cleaning Drone
The AS-50 is a tank-mounted cleaning drone for photovoltaic arrays, roofs, windows and building surfaces. It carries its own 50 L water tank instead of dragging a hose, sprays at 1 MPa and 15 L/min, and runs on two 18S 30,000 mAh smart batteries. Because the water travels with the aircraft, it can work on rooftops, carports, ground-mount arrays and low facades where a hose line cannot reach.
What the AS-50 Does
Ground-mounted solar farms are usually cleaned by truck or by hand crews walking the rows; rooftop arrays are often skipped altogether because getting water up there is the hard part. The AS-50 removes that constraint — it lifts a 50 L charge to the array, sprays a 1 MPa fan onto the panels at close range, and returns for a refill.
- On-board 50 L tank — no hose, no ground pump, no water supply on the roof
- 1 MPa nozzle pressure at 15 L/min — enough to lift dust, pollen, bird droppings and soiling film without stressing panel coatings
- T50 motors with 55-inch propellers — the lift needed to carry a full 50 L tank
- 50 kg payload, 105 kg maximum take-off weight — headroom for the tank, spray set and camera
- Dual 18S 30,000 mAh smart batteries — roughly 10 minutes of working time per charge, matched to the tank
- Obstacle avoidance radar — installed as standard for work around racking and roof edges

Where the AS-50 Is Used
Ground-mount solar farms
Row-by-row cleaning on utility and commercial arrays, working along the racking at low altitude instead of sending crews between the rows with hoses.
Rooftop and carport arrays
Commercial rooftops, warehouse roofs, factory canopies and carport arrays where running water to the panels is impractical and walking the roof is a fall risk.
Roofs, canopies and skylights
Low-slope roofs, canopy glazing and skylights on low and mid-rise buildings, cleaned with the same tank-and-spray set-up.
Windows and building surfaces
Low-level glazing, signage, cladding and canopy fascias on buildings where a hose-fed facade drone is not justified.
Cleaning Drone Model Comparison
| Model | Application | Nozzle pressure | Water flow |
| AC300 | Building exterior wall and glass below 300 m | 6,200 psi | 20 L/min |
| AC100 | Building exterior wall and glass below 100–150 m | 5,000 psi | 20 L/min |
| AC50 | Building exterior wall and glass below 50 m | 4,000 psi | 18 L/min |
| AS-50 | Solar panel and roof cleaning (with tank) | 1 MPa | 15 L/min |
| AS-30 | Solar panel and roof cleaning (with tank) | 1 MPa | 15 L/min |
Cleaning tall facades rather than arrays? The AC50 covers buildings below 50 m and the AC100 covers the 100–150 m class. For smaller arrays the AS-30 carries a 30 L tank on the same tank-and-spray principle.

Frequently Asked Questions
Does the AS-50 need a water hose on site?
No. The AS-50 carries its own 50 L tank, so the operator only needs a refill point on the ground. This is what makes it usable on rooftops, carports and between solar rows.
What pressure and flow does the AS-50 deliver?
1 MPa nozzle pressure at 15 L/min water flow — a low-pressure, high-volume wash intended for photovoltaic glass and roof surfaces.
How long can the AS-50 work per charge?
Approximately 10 minutes of flight time with the dual 18S 30,000 mAh smart battery set, which matches one 50 L tank.
What is the payload and take-off weight?
50 kg maximum load and 105 kg maximum take-off weight, with a drone weight of 45 kg without batteries.
Can it clean building facades too?
The AS-50 is specified for solar panels, roofs, windows and low building surfaces. For tall curtain walls use the hose-fed AC100 or AC50.
Can Aolan supply the AS-50 for OEM/ODM and distribution?
Yes. Aolan is a manufacturer established in 2016 offering OEM/ODM and global distributor recruitment. Minimum order quantity is 1 unit.
