Pisgah Energy Completes Guilford County’s Largest Rooftop Solar Array at Piedmont Triad Airport

Pisgah Energy, a commercial solar contractor, installed photovoltaic (PV) panels across six structures at AAR’s Airframe maintenance facility located at Piedmont Triad International Airport in Guilford County, North Carolina. The project used 7,770 QCells 590‑watt modules and 25 SolarEdge inverters. The system entered commercial operation in late 2024 and is now the contractor’s largest completed work to date.

The installation has a capacity of 4.6 megawatts direct current (MWDC). It is expected to produce over 5,900 megawatt‑hours (MWh) of renewable energy annually. Pisgah Energy’s senior project developer stated that these systems together constitute Guilford County’s largest rooftop solar installation. The on‑site generation will offset carbon emissions, power the airport’s maintenance operations, and export surplus electricity to the grid.

For AAR, the array reduces reliance on purchased electricity and supports its sustainability targets. For Guilford County, the project adds a measurable chunk of local clean‑energy capacity and demonstrates the feasibility of large‑scale solar on active airport property. For Pisgah Energy, the completion marks a milestone in its portfolio and highlights its ability to manage complex, time‑sensitive builds.
