The solar system, which consists of 7308 Sharp solar panels in a fixed, ground-mount system, was funded by the US Department of Energy and the American Samoa Power Authority (ASPA).
ASPA CEO Andra Samoa said the deployment marks a new beginning for the ASPA and the people it serves.
"Until now, we were completely dependent on diesel generators for all of our electrical power," Samoa said.
"Our new SunWize solar installation will help alleviate that dependency by providing a much-needed ‘green’ energy resource. We hope to obtain additional grant funding to install more of these clean, renewable energy sources in the near future."
ASPA’s new solar power system was installed on a 3.93-acre site near the island’s airport runway, with 2 additional acres reserved as an overflow site.
