Robots Partner with Humans for Advanced Solar Installation
An American electrical contracting company has announced that its Renewable Energy division will demonstrate a new autonomous robotic solution for solar module installation on April 17 in West Texas.
The innovative three-piece robotic system reportedly can install solar modules three times faster than manual installation methods, while simultaneously improving worker safety and addressing the persistent labor shortage in the industry.
This development comes at a critical time as energy installations increase to meet the surging demand caused by data center growth and electrification trends. During a recent webinar hosted by the National Electrical Manufacturers Association (NEMA), the president and CEO of a Chicago-based wire and cable manufacturer identified the labor shortage as one of the major "chokepoints" preventing the industry from meeting unprecedented demand growth.
During the demonstration, operators will showcase the robots' lidar-based obstacle detection and avoidance capabilities, maneuverability across challenging terrain, and precise positioning of solar modules. Using GPS and KMZ mapping technology, the robots can reportedly place modules with remarkable precision—within 2 millimeters of target locations.
The demonstration will highlight how skilled electrical teams work collaboratively alongside the robotic system to complete solar module installations efficiently.
In previous field testing on a similar solar project, robots working with a two-person crew achieved installation rates of 350-400 modules per eight-hour shift. This represents a threefold increase compared to standard manual installation methods using three to four workers.
A senior vice president at the company stated, "We created a solution that will revolutionize the installation of renewable energy facilities worldwide by providing a safer, faster, repeatable, and more cost-effective means of deploying solar installations in remote locations. Countless hours have been spent developing and testing the technology at utility-scale solar facilities, resulting in a robotics system that will assist electricians and reduce the risk of workforce injuries while addressing the construction industry's decades-long workforce shortage."
The robotic technology was developed through a partnership with a New York-based developer of robotic solutions for the energy industry.
Technical Specifications
The hybrid gas- and battery-powered system includes: - A panel-setting robot with a tracked, construction-grade platform and integrated robotic arm - Nine-vacuum suction cups to lift and place solar modules - Two panel-carrying robots that transfer pallets of solar modules between loading areas and installation points
These machines can handle loads up to 100 pounds. While the robots manage the heavy lifting, human electricians focus on securing the critical grid connections.
The working prototype is engineered to withstand various environmental challenges including extreme temperatures, wind, rain, mud, and uneven terrain with inclines up to 30 degrees.
Over the past 15 years, the company reports delivering nearly 7 gigawatts (GW) of solar project installations across the United States, Guam, and Puerto Rico. Their current portfolio includes more than 7 GW in various stages of development and over 2.5 GW under construction, spanning mid- to large-scale commercial and utility-grade solar farms in Texas, Nevada, and California.
Developers and business leaders interested in witnessing this technological advancement are invited to attend the demonstration in West Texas.
