美國已經推出最大國有土地光伏電站計劃，即在Arizona州Glendale的Luke空軍基地建立一個15兆瓦光伏電站。

    該項目將由加州SunPower代表Arizona Public Service Company全權負責，包括設計及建設。Arizona Public Service Compan將擁有該電站的所有權及運營權。

    該項目將在100英畝的土地上使用52,000 個SunPower的太陽能電池板及Sunpower的單軸跟蹤系統，追蹤劃過天空的太陽。

    該項目產生電力可滿足州內3,750個家庭的需求，根據APS的購買協議， 該電站將長期為空軍基地提供電力。

    該項目是APS授權的盧克空軍基地的第二個太陽能合作項目。2006年，該基地的戶外屋頂安裝了一個375千瓦的太陽能系統。
 
    此前，SunPower空軍合作，在內華達州的Nellis空軍基地建設了一個14.2MW的太陽能光伏項目。

 Plans have been unveiled for the largest solar power facility ever on US government property, a 15-megawatt photovoltaic plant at the Luke Air Force Base in Glendale, Arizona.

    The system is to be designed and built by California firm SunPower Corporation on behalf of the Arizona Public Service Company, which will own and operate it.

    It is to comprise 52,000 SunPower solar panels no a 100-acre site, using a single-axis tracking system to follow the sun across the sky.

    Generating enough power to supply the equivalent of 3,750 Arizona homes, the system will provide power to the Air Force Base under a long-term power purchase agreement with APS.

    The project is the second solar project for the Luke Air Force Base in which APS has partnered. A 375-kilowatt system was installed in 2006 on the Base Exchange roof.

    SunPower has also worked with the Air Force before, developing a 14.2MW facility at Nellis Air Force Base, Nevada.
