CROFT conducted a solar energy study and full engineering design for a remote, off-the-grid 36kW solar photo-voltaic power system linked to an existing battery bank and gas powered generator system at the Historic Cades Cove recreation area in the Great Smoky Mountains National Park, a protected landscape identified as a UNESCO World Heritage Site.

After a national search by the NPS in Denver, CROFT was selected to lead the technically complex process of integrating a fully off-the-grid solar photovoltaic system as the third power supply element in a legacy battery-bank and gas generator system. After a solar study and load analysis that identified a need for 30% larger system than originally projected, CROFT led the electrical, civil, and landscape architectural design to site the solar array while carefully screening it from historically significant site amenities at the Cable Mill Visitor’s Center.

The solar array provide a silent energy source to serve the small visitor center, bookstore, and restroom facility in the Cable Mill area. The panels are located behind the restroom in an area that receives maximum exposure from both morning and afternoon sun. A low berm planted with native vegetation was created around the array to minimize the visual intrusion on the historic landscape and the area’s natural beauty.  The array consist of 80 panels and occupy a 40 by 65-foot area.

The project reduced greenhouse gas emissions by 23 tons and fuel costs by $14,000 annually. Prior to development of this solar power system, the park used an aging diesel-fueled generator and battery backup system for electric power at the site. Not only was this diesel system costly and labor-intensive to operate, but caused noise disruptions to park programs and impacted the visitor experience at this remote historic landscape.
