The construction autonomy innovators at Built Robotics, have unveiled the RPD 35, billing it as the world’s first fully autonomous solar piling system. The company says utility-scale solar foundations can be constructed up to five times faster with RPD 35 than with traditional means and methods.
Piling is a complex construction activity at the heart of every utility-scale solar project. Solar piles are generally steel H-beams 12 to 16 feet in length and up to 200 pounds in weight. A typical solar farm requires tens of thousands of piles to be installed, each of which must be driven into the ground upward of eight feet and positioned at an accuracy of less than an inch. Together these piles form the structural foundation of the solar array.
The RPD 35 combines all the steps in the piling process — survey, pile distribution, pile driving, and inspection — into one package. With the RPD 35, a two-person crew can install over 300 piles per day. This is achieved through Built’s construction AI software working in tandem with a custom pile cartridge system and advanced sensors like RTK GPS.
“Solar piling is a tough, repetitive job, one well suited to automation,” said Noah Ready-Campbell, founder and CEO of Built Robotics. “Our piling robots will dramatically improve the efficiency of workers on jobsites, which is critical in the chronically tight construction labor market. And just as importantly, they will take people out of harm’s way, reducing noise exposure, strain, struck-by and pinch hazards.”
Built has a successful track record of developing robots for the solar industry, with its first commercial deployment occurring in 2018. Since then, Built’s robots have helped to install over 2 GW of solar capacity across the country, enough to power over 400,000 homes.
Built is scheduling the first customer deployments of the RPD 35 for Q4 2023.
