Multiple Solar Systems – National Institute of Standards and Technology (NIST)

Ground mounted solar system at NIST providing renewable energy to the Advanced Measurement Laboratory

This 247 kW ground mount system was built using a fixed-tilt rack structure and concrete foundations.  Legatus6 encountered poor soil condition at the required footer depth and employed a testing agency to certify the bearing capacity for each set of foundations to ensure no shifting would occur over time.  The Maryland Department of the Environment has very stringent requirements for mitigating storm water run-off.  Consequently there was a heavy site component for this portion of the project that required three storm-water bio-retention areas totaling 3400 square feet of surface area and storm-water connections 17 feet below grade.  Legatus6 managed these challenges while completing the ground mount system (and the entire project) on schedule.
