SAN DIEGO, June 11, 2013 /PRNewswire/ --Maxwell Technologies, Inc. (Nasdaq:
MXWL) and Soitec (Euronext, Paris) announced today that they will collaborate
on a California Energy Commission-funded, two-phase program to demonstrate the
cost and efficiency benefits of combining an energy storage system with
Soitec's Concentrix™ CPV technology.

Maxwell has been awarded a $1.39 million contract by the California Energy
Commission's Research and Development program to fund design and integration
of an ultracapacitor-based energy storage system with Soitec's CPV system
located on the campus of University of California, San Diego—one of the
nation's greenest universities— and a second commercial scale system at
Soitec's solar power plant in Southern California. The integrated systems will
also take advantage of other technology advances, including solar forecasting
and predictive energy control, to maximize the benefit of incorporating
ultracapacitor energy storage. 

The project starts in June 2013 and will run through November 2015.
Independent evaluation of the performance of the integrated systems will be
performed by DNV KEMA under a sub-contract with Maxwell.

"This innovative energy storage system combining ultracapacitors and Soitec's
CPV technology, which is already installed on campus, is a welcome addition to
UCSD's existing microgrid and provides a unique diversification of our
existing energy storage capacity," said Byron Washom, director of strategic
initiatives, University of California, San Diego.

"Investing in solar energy research is vital to California reaching its goal
of 33 percent renewable generation by 2020," said California Energy Commission
Chair Robert B. Weisenmiller. "This innovative project combining energy
storage with concentrated photovoltaic technology has the potential to
increase the state's renewable energy portfolio, decrease greenhouse gas
emissions, and create a more reliable electricity grid."

Soitec's new fifth-generation Concentrix CPV systems incorporate modules with
a 30 percent market-leading module efficiency (or two to three times the
efficiency of conventional PV technology). CPV technology converts sunlight
directly into clean electricity via concentrator optics and high-efficiency
solar cells, offering the best design for use in sunny regions as it delivers
environmentally friendly, low-cost, reliable solar-generated electricity.
Additionally, the CPV system's two-axis tracker allows a high and constant
power production throughout daylight hours.

Ultracapacitors are energy storage devices that charge rapidly from any
electrical energy source and discharge their stored energy on demand. In
combination with a photovoltaic system, their function will be to act as a
standby reservoir of electrical energy to mitigate the variability of solar
energy generation.

This firming of the output of a utility-scale commercial CPV system is
intended to reduce demand on the electric grid to fill in short-term solar
valleys in order to maintain a facility's electricity output. In addition to
reducing the variability of a solar power plant, integrated ultracapacitor-CPV
systems will benefit public utility customers by reducing investment in
utility generation capacity to meet transient peak power demand.

"We are pleased by this new project with Maxwell Technologies," commented
Clark Crawford, vice president of U.S. sales and business development, Soitec
Solar division. "Soitec's durable CPV systems are specifically designed to
deliver higher efficiency and lower cost of electricity. By working together,
we are confident that we can improve the integration of solar power plants
into the grid and ultimately increase the penetration of solar in the
electricity grid helping California to meet its 33 percent renewable portfolio
standard (RPS) goals."

Unlike batteries, which produce and store energy by means of a chemical
reaction, Maxwell's ultracapacitor products store energy in an electric field.
This electrostatic energy storage mechanism enables ultracapacitors to charge
and discharge in as little as fractions of a second, perform consistently over
a broad temperature range (-40 to +65C), and operate reliably for up to one
million or more charge/discharge cycles.

"Electric utility grid applications represent an exciting new frontier for
Maxwell," said David Schramm, Maxwell's president and chief executive officer.
"This program is providing an opportunity to demonstrate how ultracapacitor
technology can be applied to provide more efficient and cost-effective
solutions for a variety of short-term power requirements."
