Solar Piling

Drive Results by Automating Pile Installs

All Gain. No Pain.

Piling is demanding, and traditional means and methods are being pushed to their limits. Built engineers have spent thousands of hours developing an advanced autonomous solution that can rise to meet the challenges of utility-scale solar.

The Bold Standard: The RPD 35

Don’t compromise on your tools. The RPD 35 is a fully autonomous robotic pile driver that combines four steps — surveying, pile distribution, pile driving, and data collection — into a single step. Take advantage of the superior production and efficiency gains that only a robot can deliver, and outshine the competition.

A Powerful Sidekick: The RPS 25

Every RPD 35 pairs with an RPS 25. The robotic pile stabilizer ensures driven piles exceed the most stringent tracker tolerances and produce consistently placed piles every time: accurate z-heights, perfect plumbness, and unrotated piles.

Advanced Robotics

With intelligent sensor fusion, AI-powered vision systems, real-time production data, and edge computing, the most advanced construction autonomy is now available for piling on solar farms.

Safer Results. Safer Work.

Make jobsites safer with autonomous tools. An 8-Layer Safety System keeps workers safe around the robot. With autonomous piling, workers can avoid the extreme weather, sound, struck-by, and caught in-between accidents common with manual operation.

Tight Tolerances

Nothing compares to the accuracy and precision of a robot. Achieve results that repeat themselves from the first pile to the very last to help enable issue-free tracker installation.

Lower Costs

Drive more, spend less. Robotics lower installation and labor costs. The RPD 35 frees up valuable labor to focus on critical tasks letting solar developers optimize piling costs to stay competitive and win the market.

Maximum Uptime

Unlock a new way of running your business. Robots reduce schedule uncertainty, limit rework, and operate with little interruption, which maximizes equipment utilization and uptime to create productivity unseen with traditional means and methods.
