Strategic FAQ for WLS-7 Solar Cleaning Robot
Q1: What are the primary benefits of using the WLS-7 robotic solar cleaner over manual labor?
A: The WLS-7 offers a high-efficiency alternative to traditional manual cleaning, which is often slow and labor-intensive. Key advantages include:
Cost Reduction: Dramatically lowers labor costs by automating the maintenance process.
Higher Yield: Cleans up to 1.2MW per day, significantly increasing the energy output of the PV station compared to handheld tools.
Personnel Safety: Solves cleaning challenges in hazardous environments where technicians cannot safely stand or reach.
Q2: How does the WLS-7 ensure safety on tilted or slippery solar panels?
A: Stability and safety are core features of the WLS-7 design:All-Terrain Tracked Chassis:
The robot uses a specialized anti-slip caterpillar track system for stable movement in any direction.
Anti-Fall Technology: It is equipped with four intelligent sensors (front and rear) that detect the edge of the panel and trigger a stop command to prevent falling.
Slope Adaptability: Engineered to operate efficiently on solar arrays with tilt angles of 10°, 15°, and 20°.
Q3: Can the WLS-7 robot be used for waterless (dry) cleaning in desert regions?
A: Yes, the WLS-7 is a dual-mode cleaning solution. It features an electric rolling brush that can perform dry cleaning to remove dust and sand.
For stubborn grime, it also includes integrated water spray nozzles for wet washing.
Q4: What is the remote control range for the WLS-7 solar cleaning robot?
A: The device utilizes a high-frequency wireless remote control with a functional distance of up to 150 meters. This allows operators to manage cleaning cycles from the ground or a safe distance, increasing site flexibility.
Q5: What are the maintenance requirements for the WLS-7 battery and brushes?
A: To ensure long-term performance, follow these guidelines:
Storage: Store the robot tipped up to keep the brush bristles in the air and prevent deformation.
Battery Care: Recharge the lithium battery once every 2 months during storage to prevent loss of capacity.
Warranty Support: The drive motor and lithium battery are covered by a 12-month warranty, while electronic components have a 6-month warranty.
Q6: Is the WLS-7 easy to transport and install on-site?
A: Absolutely. The robot is designed for portability with a unit weight of only 23KG. It is shipped in professional packaging including a wooden case for the body (79*74 *49cm) and a separate case for the 1.2m brush. Installation is a simple 3-step process: install the battery, connect the water supply, and place it on the panel.
