Design Achievement – DLR Group teamed with Pivot Energy in the design of a 346kW solar canopy system to produce clean energy at the Mount Rushmore National Memorial in Keystone, South Dakota. The solar canopy is located on top of a nearby parking structure protecting visitors from the elements, and framing unobstructed views of the memorial.
Scope Summary – The Thomas Jefferson Solar Canopy at Mount Rushmore provides power for the concessions and visitor's center. The system is expected to generate almost 500,000 kilowatt hours and save the park $40,000 in energy costs annually. The canopy, powered by 975 solar panels mounted on the parking structure, is strategically designed to prohibit obstructing views of the memorial when parking at the site. The array is positioned on the top of the Washington Parking Garage, and is designed with a dual tilt configuration. The northern half of the structure is tilted at 5 degrees for production purposes but also ensures that visitors do not lose sight of the memorial when standing on the top level of the garage. The southern half is at a minus-1-degree slope to catch any snow that slides down from the northern half of the array and direct any moisture away from patrons. DLR Group provided electrical design and engineering services.
