Product Description

WLS-9YQ-LD1 Intelligent Solar Panel

The WLS-9YQ-LD1 is an advanced solar panel cleaning drone designed for large-scale photovoltaic plants and distributed PV projects. It overcomes the limitations of traditional cleaning methods in challenging terrains, offering efficient, safe, and non-destructive cleaning for solar panels. Ideal for rooftops, deserts, mountainous areas, and other hard-to-reach locations, this ensures high-performance operation with zero physical contact.

Key Features & Advantages

Heavy Payload, High Efficiency
The washing drone Carries up to 60 kg of cleaning liquid per trip, reducing refill frequency and increasing continuous operation time.
Enhances solar cleaning efficiency, covering larger areas in less time.
Precise Dual-Antenna RTK Positioning
Equipped with a high-accuracy dual-antenna RTK system for stable and precise navigation.
Includes FPV HD camera and landing lights for safe night operations and real-time monitoring via LCD display.
All-Terrain Applicability
Capable of flying at 0–150 m altitude, making it a versatile roof cleaning drone and building cleaning drone.
Suitable for deserts, hills, rooftop PV systems, and large ground-mounted power plants.
Outperforms traditional solar cleaning robots that rely on tracks or flat surfaces.
 Efficient & Safe Zero-Contact Cleaning
Uses a high-pressure spray system to clean panels from the air—no direct contact, no scratches.
Eliminates risks associated with manual cleaning, such as climbing and abrasive brushing.
Smart Route Planning & Water Saving
Automatically generates edge-sweeping paths to prevent missed spots.
Reduces water consumption by 30–50% compared to manual pipe washing—making it an eco-friendly solar panel cleaning system.
Industrial-Grade Durability
Constructed with a full aviation aluminum frame for lightweight yet impact-resistant performance.
Sealed core components prevent dust and chemical corrosion, ensuring long service life and low maintenance.

FAQ

Q1: What is the maximum coverage area per flight for the WLS-9YQ-LD1?
A: With a full load of 60kg cleaning liquid, the drone can clean approximately 200–500 m² per cycle, depending on the soiling level and panel layout.

Q2: Can this drone be used at night or in low-light conditions?
A: Yes. It is equipped with FPV HD cameras and landing lights, allowing safe and efficient operation during night or low-visibility conditions.

Q3: Is the drone suitable for cleaning rooftop solar panels?
A: Absolutely. The WLS-9YQ-LD1 is an ideal roof cleaning drone and building drone, designed to operate safely and efficiently on rooftop PV systems without the need for scaffolding or manual climbing.

Q4: How does the drone avoid damaging the solar panels during cleaning?
A: It uses a non-contact, high-pressure spray system that cleans without physical abrasion. This prevents scratches and micro-cracks commonly caused by brushes or manual cleaning.

Q5: What kind of cleaning liquid can be used with this drone?
A: The system is compatible with most common solar panel cleaning solutions or deionized water. We recommend using eco-friendly, non-abrasive liquids to ensure panel longevity.

Q6: How is the drone different from a solar cleaning robot?
A: Unlike solar cleaning robots that require rails or flat surfaces, this drone is track-free and adaptable to complex terrains like roofs, hills, and deserts. It offers greater flexibility and zero installation cost.

Q7: What is the flight time under full load?
A: Under full load (60kg), the flight time is approximately 9 minutes. Without load, it can fly up to 35 minutes.

Q8: Does the drone support autonomous flight?
A: Yes. With the built-in dual-antenna RTK system and smart route planning, it can autonomously generate cleaning paths, including edge-sweeping routes to prevent missed spots.
