SAN JOSE, Calif.and TOKYO, Sept. 29, 2013 /PRNewswire/ -- SunPower
Corporation (NASDAQ: SPWR), a leading solar technology and energy solutions
provider, today announced it will supply 69-megawatts (MW) of its high
efficiency E20/327 solar panels to Shimizu Corporation for installation at the
Eurus Energy mega solar power plant project in the village of Rokkasho,
Aomori, Japan. With this agreement, SunPower is providing clean energy to
Japan's largest solar installation.

Shimizu, a leading architectural, engineering and general contracting firm in
Japan, will act as the engineering, procurement and construction (EPC)
provider for the project which is owned by Eurus Rokkasho Solar Park
Corporation, a subsidiary of Eurus Energy Group. It is scheduled for
commercial operation in the second half of 2015.

"The proven efficiency and reliability of the modules from SunPower
Corporation, coupled with the industry's best warranty, will enable us to
build a power plant that will benefit the community of Rokkasho," said Eurus
Rokkasho Solar Park Corporation President Satoshi Takahata.

Integrated into the E20/327 solar panels by SunPower Corporation are its
Maxeon® all-back contact solar cells. These cells are built on a solid copper
foundation, making them extremely resistant to cracking, corrosion and
stresses from temperature variation. With an efficiency of 20.1 percent, the
E20/327 panels deliver more power in the same amount of space and maximize
system output with fewer panels installed.

The company's solar panels are backed by the company's straightforward 25-year
combined product and power warranty. It offers the industry's lowest power
degradation with more warranted energy, resulting in an unprecedented 87
percent power level at the end of 25 years.

"We are pleased that Eurus chose SunPower Corporation for two mega solar power
plant projects in Japan," said Howard Wenger, SunPower president, regions.
"The Japanese market continues to respond well to our high efficiency solar
products for all customer segments -- residential, commercial and
utility-scale."

SunPower Corporation will also supply 27.4 MW of its E20/327 solar panels to
Obayashi Corporation for installation at the mega solar power plant project in
Toyokoro, Hokkaido, Japan, which is also owned by a subsidiary of Eurus Energy
Group. Obayashi will act as EPC and the project is scheduled for commercial
operation in 2015.

Solar products by SunPower Corporation are branded under the Maxeon Solar name
in Japan. The capacity of mega solar power plants in this release is
described in approximate megawatts on a direct current (dc) basis unless
otherwise noted.
