National Bank of Arizona (NBA), Phoenix; SolarCity, Foster City, Calif.; and First Solar, Tempe, Ariz., recently announced plans to build a 222kW solar installation in Phoenix, which will be the city's second largest commercial solar installation to date. The project, comprising two carport-mounted solar systems, will be the first commercial solar installation in Phoenix to use Tempe-based First Solar's advanced thin film modules.

The solar systems will consist of 2,960 First Solar modules.
