Rosendin, a US-based electrical contractor, planned a live demo on April 17, 2025, in West Texas to show its new robotic system for installing solar panels. Developed in partnership with ULC Technologies, the system includes one Panel Setting Robot and two Panel Carrying Robots. It can move across rough ground, avoid obstacles using LiDAR, and place panels accurately using GPS. The robots are powered by a mix of gas and battery and use suction cups to lift heavy panels. In testing at another site in Danevang, Texas, the system installed 350 to 400 panels in an eight-hour shift with just two workers—about three times faster than doing it manually. The system can work on its own or be controlled by people.
