South Carolina Electric & Gas Company (SCE&G) and Boeing South Carolina (BSC) partnered in 2011 to build a large solar electric generator on the rooftop of the new BSC 787 Dreamliner Final Assembly Facility located in North Charleston, SC. The teams worked together through numerous challenges in constructing a facility on a rooftop not designed for traditional solar panel generation. This paper will discuss the technical challenges that had to be overcome and how this project fits into BSC renewable energy commitment for this facility. The project consists of the installation of over 18,000 thin film laminate solar panels, mounted on a 15 acre roof. The facility uses four inverters, each rated at 700 kW, for a total installed system nameplate rating of 2800 kW. The inverters are close coupled to 480 VAC to 13.8 kVAC transformers. The 13.8 kVAC power is delivered to and solely used by the BSC facility via a 13.8 kVAC breaker in the switch gear building.
