SAN JOSE, Calif., March 25, 2014

SAN JOSE, Calif., March 25, 2014 /PRNewswire/ -- SunPower Corporation (NASDAQ:
SPWR), a leading solar technology and energy services provider, today
announced the sale of more than 70 megawatts (MW) of cell packages to the
Huaxia Concentrated Photovoltaic Power Co., Ltd., joint venture (JV) in Inner
Mongolia, China. These packages will be used for the first phase of two
SunPower™ C7 Tracker (C7) projects, which includes a 20-MW project in Saihan
and a 100-MW project in Wuchuan. Both are located in Hohhot, Inner Mongolia
and completion is expected in 2015.

"Today's announcement is a first step in our aggressive efforts to break into
the Chinese market," said Tom Werner, SunPower president and CEO. "Working
together with our strong local partners, we believe that we can deploy
significant volumes of our SunPower C7 Tracker power plants to help serve
China's growing need for clean power."

The definitive agreement for the Huaxia Concentrated Photovoltaic Power JV was
initially signed in December of 2012, and officially approved and registered
in November of 2013. The JV includes SunPower, Tianjin Zhonghuan
Semiconductor Co., Ltd., Inner Mongolia Power (Group) Co., Ltd. and Hohhot
Jinqiao City Development Company, Ltd. Its focus is to manufacture and deploy
SunPower's proprietary C7 concentrator technology in the Chinese market. To
date, a 300-MW C7 receiver manufacturing facility has been set up in Jinqiao
Development Zone, Hohhot, Inner Mongolia, and a 50-MW production line is now
in operation.

The C7 combines single-axis tracking technology with rows of parabolic mirrors
that reflect light onto SunPower's high efficiency, third-generation Maxeon
solar cells with efficiencies of up to 24.5 percent. These mirrors will
reduce the number of cells required to generate electricity, lowering the
levelized cost of energy when compared to competing technologies. For
example, a 400-MW C7 power plant requires less than 70 MW of SunPower cells.
Through significant localization of C7 manufacturing and supply chain, and
deployment of the C7 for large-scale power plant projects, it is expected that
this venture will facilitate the development of a low cost, high volume supply
chain and accelerate the cost reduction roadmap of this product.

The capacity of cell packages and power plant projects in this release are
described in approximate megawatts on a direct current (dc) basis.
