WLS-7-LM Intelligent Solar Panel Cleaning and Inspection Robot
Built by WANLV SUNNY

Overview
The WLS-7-LM is an intelligent solar panel cleaning and inspection robot designed for large-scale photovoltaic (PV) power stations. It features dual-mode operation (manual and autonomous), adaptive cleaning angles, and real-time fault detection, ensuring efficient, safe, and smart maintenance in dusty or remote environments. Ideal for utility solar farms seeking to reduce O&M costs and improve energy output, it adapts to different panel tilt angles and heights, making it suitable for various ground-mounted PV installations. The robot includes intelligent sensors for monitoring pressure, tilt, alignment, and cleaning conditions, and can identify abnormal panel conditions automatically.
