Built Robotics’ autonomous excavators for solar pile driving can operate continuously around the clock when needed.
Addressing Labor Shortages in Solar Energy Projects
To meet the surging demand for solar energy infrastructure and mitigate workforce constraints, Blattner, a subsidiary of Quanta Services and a leading utility-scale EPC contractor, has partnered with Built Robotics to deploy autonomous pile driving machines on solar installation sites.
How Autonomous Excavators Enhance Solar Panel Foundations
These advanced machines are modified hydraulic excavators outfitted with vibratory pile driving tools, capable of handling and installing large steel piles that form the foundational support for solar panel arrays. Given the variability of soil conditions and the repetitive, labor-intensive nature of pile driving, this task is traditionally one of the most hazardous and physically demanding in solar construction.
Continuous Operation and Safety Features
Equipped with onboard storage for steel piles, these autonomous excavators can operate nonstop-24 hours a day-provided they receive timely refueling and material replenishment. Integrated sensors enable precise navigation and human detection to ensure safe operation on site. Typically, two robots collaborate on each project: one positions the pile, while the other drives it into the ground.
Boosting Productivity and Project Timelines
Noah Ready-Campbell, CEO of Built Robotics, highlights the productivity gains: “On some projects, our robots have achieved 2.5 times the output in a single week by working continuously.” This capability allows project schedules to be adjusted dynamically, reducing delays caused by labor shortages or unforeseen setbacks. “If one crew falls behind, the entire timeline can unravel. With robotic teams running around the clock, we can accelerate progress whenever necessary,” he explains.
Innovative Automation Solutions for Heavy Equipment
Built Robotics specializes in retrofitting existing heavy machinery with autonomous control systems, transforming hydraulic excavators and similar equipment into robotic operators for repetitive construction tasks such as trenching and pile driving. Their solar pile driving solution, launched in 2023, has been adopted by contractors nationwide, including Blattner, with this latest agreement marking one of the largest deployments to date.
Expanding Reach Across North America’s Sun Belt
Currently active on their fourth project with Blattner, Built Robotics plans to extend their autonomous fleet across the United States and Canada. The majority of these solar installations are concentrated in the Sun Belt region-states like Texas, Arizona, California, and Florida-where abundant sunlight drives solar energy growth. Blattner anticipates utilizing dozens of these robotic pile drivers to meet project demands.
Enhancing Safety, Quality, and Client Confidence
Brandon Buski, Vice President of Solar at Blattner, emphasizes the benefits: “Partnering with Built Robotics eliminates the risks associated with manual pile driving, while simultaneously improving quality, accelerating schedules, and providing greater certainty to our clients.” Quanta Services acquired Blattner in 2021 for $2.7 billion, underscoring the strategic importance of integrating cutting-edge automation in solar construction.
Rethinking Solar Foundations with Robotic Capabilities
Ready-Campbell envisions a future where automation reshapes project design: “With robots capable of lifting up to 8,000 pounds-far beyond the 500-pound limit for humans-we can explore new foundation designs using heavier piles.” He stresses the importance of collaboration with experienced crews, stating, “We learn from seasoned professionals and ensure our robotic processes fit seamlessly into existing workflows, delivering a high-quality foundation for subsequent teams.”
