Solar Piling The Heart of Utility-Scale Solar
As more gigawatts of solar capacity are added to the grid, contractors need innovative ways of driving pile that can handle the tight tolerances, uneven terrain, and varying pile dimensions required for today’s solar arrays. Automation is a field-proven solution that can restore schedule certainty on even the most challenging projects.
Less Pain. More Gain.
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.

Technology
The Bold Standard
Don’t compromise with your tools. The RPD 35 is a fully autonomous robotic pile driver that combines four steps — surveying, pile distribution, pile driving, and as-builts — into a single robot. Take advantage of the superior production and efficiency gains that only a robot can deliver, and outshine the competition.
Compatibility
On the Right Track
Minimize installation hours. Maximize gigawatt hours. Our flexible autonomous piling solution is compatible with tracker systems from all of the leading manufacturers. The RPD 35’s tracker-first capabilities ensure seamless installation from survey to grid connection.
