Multinational Solar Company Moves into Tucson’s UA Tech Park Solar Zone

(Tucson, Arizona) The University of Arizona Science and Technology Park (UA Tech Park) is pleased to announce its newest, multinational, solar tenant — AstroSol Tech Park AZ LLC (AstroSol).

AstroSol will own and operate a 6.1 megawatt solar photovoltaic facility using thin-film, amorphous silicon modules from Astronergy, mounted on a fixed-tilt racking structure from Schletter. The power generated from the facility will be sold directly to Tucson Electric Power (TEP) and distributed to the metropolitan area of Tucson.   AstroSol anticipates the project to displace over 7,700 metric tons of carbon dioxide, meeting the electrical requirements of about 1,000 homes per year. The multinational solar company is a partnership between Astronergy Solar Inc., a Chinese solar panel maker, and Solmotion GmbH, a German solar project developer, uniting into the newly formed company AstroSol Inc., who owns all member interest in the special purpose project company AstroSol Tech Park AZ LLC.  The project is managed by vis solis LLC, Franklin, TN, the U.S. subsidiary of Solmotion.

This project will bring a new solar technology application into the Solar Zone.  With the industry`s average conversion efficiency currently between 6-8%, the 9% conversion efficiency of Astronergy`s thin film makes it highly competitive for use in many large-scale applications. The manufacturing process consumes fewer raw materials and less energy, which makes it more cost effective, closing the gap between renewable energies and traditional energies.  Under high temperatures like in Arizona and low light, Astronergy`s high efficiency tandem thin film modules convert electricity more effectively than many other types of photovoltaic modules.   
“We literally hit the ground running the last week of December 2011,” said Carlos Mayer, Managing Owner of vis solis LLC as well as Chief Operating Officer of AstroSol Inc.  “This was possible because of the great relationship Astronergy had built with the Tech Park Authorities, Tucson Electric Power, North American Development Bank, and other stakeholders of the project.”   

Power generated by the AstroSol array will be provided to TEP customers through a 20-year purchase power agreement. With more than 25 megawatts (MW) of solar generation online already, TEP expects to dramatically expand that capacity to more than 200 MW by the end of 2014 through a combination of company-owned resources, privately developed projects and distributed generating systems.

“We’re very pleased to be working with AstroSol to help bring this significant project to the Solar Zone,” said David Hutchens, President of TEP and its parent company, UniSource Energy Corporation (NYSE: UNS). “AstroSol’s array will produce clean, green energy for our customers using one of Arizona’s greatest natural resources – sunshine.”

AstroSol Tech Park AZ LLC recently received certification from the Border Environment Cooperation Commission and received financial approval for a $13.15 million loan from the Board of Directors of the North American Development Bank to construct the project.  Construction on the 38.5-acre parcel of land in the Solar Zone commenced in December 2011 with power generation anticipated in May 2012.

The Solar Zone is the ideal environment for cutting-edge solar technologies to be evaluated side-by-side. The UA Tech Park has emerged as one of the leaders for the testing and evaluation of leading solar technologies at the utility grid level,” said Bruce Wright, the Associate Vice President for University Research Parks.  “AstroSol and vis solis complement the Solar Zone with its unique multinational perspective and technology collaboration.”
