National Bank of Arizona plans to install a $2 million solar system on its Tucson headquarters this summer, constructed by Natural Power and Energy.
At 402.6 kilowatts, the project is the second largest corporate install in Tucson. The 24,000-square-foot installation of 1,320 panels will be placed on three structures located on the rooftop of its parking garage at the bank headquarters at Wilmot Road and Carondelet Drive.
The system will reduce electricity costs of the two buildings by about 25 percent and produce at least 580,000 kilowatt hours annually within the buildings that total 128,824 square-feet. The reduction in electricity equates to the average annual consumption of 55 homes in Tucson.
