First Solar CdTe cells to shine in Arizona
At full capacity, the electricity generated by Agua Caliente, which uses cadmium telluride First Solar modules is enough to serve more than 225,000 homes.
NRG Energy has completed its acquisition of the 290 MW Agua Caliente solar project from First Solar,
The system will be used for the application of sodium fluoride solution, a process claimed to improve the overall efficiency of the cell. Ultrasonic Systems says the PV-480 leverages USI’s proprietary, nozzle-less ultrasonic spray head technology for a more uniform and repeatable coating deposition vs. conventional air atomizing spray nozzle, conventional ultrasonic nozzle, and roll coating technologies.
Designed for high-volume in-line manufacturing, the PV-480 processes glass plates up to 48 inches wide at line speeds of up to six feet per minute. The PV- 480 delivers liquid coating with transfer efficiencies in excess of 90%, utilising a traversing Ultra-Spray blade head. This versatile system is ideal for the application of a variety of low viscosity liquids used in the manufacture of thin film photovoltaic cells.
“The PV-480 complies perfectly with our expectations and provides excellent coating performance,” said Herve Rivoal, Chemistry Section Head of Nexcis Photovoltaic Technology. “We are pleased with our growing success with thin-film solar manufacturers requiring the latest manufacturing equipment technology to create reliable, efficient thin-film modules,” said Stuart Erickson, President of Ultrasonic Systems. “The latest PV-480 installation reflects the success of our unique nozzle-less spray head technology for spray coating applications critical to CIGS thin-film solar production.”
The acquisition was contingent upon the financial closing of the project’s loan guarantee from the U.S. Department of Energy’s Loan Programs Office.
Agua Caliente is one of the world’s largest solar photovoltaic project currently under construction. The Yuma County, Arizona project has obtained all permits and approvals from both federal and state agencies, and is expected to create up to 400 construction jobs through its completion date in 2014. Financial terms of the sale of the project were not disclosed.
“Agua Caliente demonstrates the extraordinary progress the U.S. has made to achieving energy independence through public-private collaboration and technological innovation,” said Tom Doyle, CEO of NRG Solar.
“Construction of the Agua Caliente system will create hundreds of new jobs in local communities, supporting economic growth alongside environmental sustainability. The sheer scale of the project will also help drive developments needed to deploy even larger and more efficient clean-energy resources in the future.”
“Agua Caliente is a major milestone for utility-scale solar,” said Frank De Rosa, First Solar senior vice president of North American project development. “We are pleased to continue working with NRG in adding significant renewable generation resources to the U.S. electrical grid, delivering both economic and environmental benefits.”
Electricity from Agua Caliente will be sold under a 25-year power purchase agreement with Pacific Gas and Electric, helping California to meet its ambitious renewable energy goals. At full capacity, the electricity generated by Agua Caliente is enough
