 INTEGRATING ENERGY STORAGE WITH CONCENTRATING PHOTOVOLTAIC (CPV) TECHNOLOGY



  California Energy Commission to Fund Design and Installation at two Sites



SAN DIEGO, California, June 11, 2013 - 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(TM) 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 UC 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 started in June 2013 and will run through November 2015.
Independent evaluation of the performance of the integrated systems will be
performed by BEW Engineering under a sub-contract with Maxwell.

"This innovative energy storage system combining ultracapacitators 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, UC 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% market-leading module efficiency (or 2 to 3 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 2-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" 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 US 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% 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."
