Five buildings at US Navy base Pearl Harbor, known now as the Joint base Pearl Harbor-Hickam, in Oahu, Hawaii are in the midst of a US$15 million project, funded by the American Recovery and Reinvestment Act. Intended to increase the base’s energy independence by using renewable energy, a combined 2.4MW solar array has been installed using SolarWorld panels, which include its crystalline silicon technology, and is spread across five buildings at the historic base.
