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.
