NPS Great Smoky Mtns Off-the-Grid Solar PV

NPS Great Smoky Mountains Off-the-Grid Solar Power System




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 Great Smoky Mountains National Park.

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.

Located at a UNESCO World Heritage Site, this complex, lean-budget project was enhanced by CROFT's expertise in public involvement and interfacing with SHPO representatives to ensure the historic character of the site is maintained while accommodating the long-term operational demands for life-support amenities at Cades Cove.
