Johnson Controls, Inc. (JCI) has completed a 12 kilowatt (kW) solar photovoltaic (PV) power system installation at the U.S. Penitentiary and Federal Prison Camp (USP/FPC) in Tucson, Arizona. The system is part of an 18-stall parking structure that also provides shading for vehicles on site. The system has 72 photovoltaic modules, with 170 watts each capacity and three 4 kW solar inverters.

According to Bill Guiney, JCI solar program manager, the system will generate 20,351 kilowatt hours of electricity per year, offsetting more than 28,491pounds carbon dioxide.

“We are proud to be working with federal government agencies to help meet their goal to use renewable solutions for at least five percent of their energy needs,” said Don Albinger, vice president of renewable energy solutions at JCI. “The project at the U.S. Penitentiary in Tucson is a solution that underscores Johnson Controls’ commitment to leveraging renewable energy in every appropriate application—in this case for both energy and shade in a hot Arizona climate.”

JCI has put in a series of parking shade structures to support the system. The parking structure allows the mounting flexibility needed for the PV system.
