DURHAM, N.C. -- November 19, 2012

Semprius, Inc., an innovator in high concentration photovoltaic (HCPV) solar
modules, will be supplying its state-of-the-art technology in support of Pratt
& Whitney Rocketdyne’s (PWR’s) $2.3 million award from the Environmental
Security Technology Certification Program (ESTCP) office of the U.S.
Department of Defense (DoD). The project is designed to demonstrate the
high-performance and cost-effectiveness of HCPV technology for use at DoD
installations as well as in other commercial and utility scale applications.

As part of the project, PWR will install a 200 kilowatt solar system at
Edwards Air Force Base in California. The system will be comprised of 2,400
Semprius modules mounted on dual-axis trackers and will produce over 400,000
kWh of electricity annually, enough to power approximately 40 homes.

Semprius’ manufacturing facility, located in Henderson, North Carolina, uses a
proprietary process to deliver the world’s highest efficiency solar modules.
At 33.9 percent, Semprius’ modules are the first to convert over one-third of
the sun’s energy into electricity. In addition, Semprius modules perform
better than conventional modules under high temperature conditions, and in
locations like the US Southwest, Semprius-based systems can deliver up to 30
percent more energy than equivalent PV systems.

“We are honored to be working with PWR to deliver our HCPV modules to the
DoD,” said Joe Carr, CEO of Semprius. “We believe that our technology will
play an increasingly important role in delivering cost-competitive,
sustainable energy.”

Semprius and PWR, part of United Technologies Corp. (NYSE:UTX), began working
together in 2011 to demonstrate Semprius’ technology at the University of
Alabama-Huntsville. Over the past 18 months, the companies have collaborated
to scale-up the technology into a cost-effective, commercial-grade system.

“Having spent several years evaluating emerging PV technologies, we’ve
selected Semprius because of the potential of their technology to drive down
the cost of solar electricity significantly,” said Randy Parsley, Renewable
Energy Program Manager at PWR. “We look forward to executing this project with
Semprius to help the DoD begin to achieve its energy independence and energy
security goals.”


Semprius, Inc. holds the world record for solar module efficiency, reaching
33.9 percent. Using the world’s smallest solar cells and applying
state-of-the-art manufacturing processes, Semprius is leading the way to
cost-competitive, sustainable solar electricity. Semprius was named to MIT
Technology Review’s 2012 TR10, an annual list of the world’s 10 most important
emerging technologies. Semprius’ headquarters and production facilities are
located in North Carolina, USA. For more information, please visit
