A 38.5-acre photovoltaic array is the latest addition to the Solar Zone technology demonstration area at the University of Arizona Science and Technology Park.
The 6.1-megawatt system was built by AstroSol, a subsidiary of German solar developer Solmotion GmbH, in partnership with Astronergy, a Chinese solar manufacturer.
Astrosol CEO Michael Volz was on hand to screw the last solar panel in place at a dedication event Friday.
The new system uses thin-film, amorphous silicon modules mounted on a fixed-tilt racking structure built in Tucson by Schletter Inc.
Power generated from the facility will be sold to Tucson Electric Power Co. under a 20-year agreement. AstroSol expects the project to displace more than 7,700 metric tons of carbon dioxide, while providing power for about 1,000 homes.
The project was financed partly through a $13 million loan from the North American Development Bank, a financial institution funded equally by the governments of the U.S. and Mexico.
