SAN JOSE, Calif., Dec. 3, 2012

SAN JOSE, Calif., Dec. 3, 2012 /PRNewswire/ --SunPower Corp. (NASDAQ: SPWR),
a Silicon Valley-based manufacturer of high-efficiency solar cells, solar
panels and solar systems, today announced that it signed a definitive
agreement to form a joint venture with partners Tianjin Zhonghuan
Semiconductor (TZS), Inner Mongolia Power Group (IMP) and Hohhot Jinqiao City
Development Company (HJCD) for the manufacturing and deployment of the
company's proprietary SunPower® C7 Tracker (C7) concentrator technology in the
Chinese market.

The joint venture, based in Hohhot, Inner Mongolia, PRC, will manufacture and
deploy SunPower's high efficiency, C7 concentrator solar systems in Inner
Mongolia and other regions in China. Under the terms of the definitive
agreement, SunPower will invest $15 million, of the total capitalization of
the joint venture of $60 million, for a 25 percent ownership stake. The joint
venture is subject to the approval of the PRC government with initial C7
deployment expected to begin by the end of 2013. 

"This agreement capitalizes on the capability of SunPower's next generation C7
technology to deliver industry leading cost effective energy," said Tom
Werner, SunPower president and CEO. "Working together with our team of strong
local partners who bring different strengths to this project, we believe that
we can deploy significant volumes of C7 power plants to help serve China's
growing need for clean power. We also expect that this venture will
facilitate the development of a low cost, high volume C7 supply chain and
accelerate our C7 cost reduction roadmap."

"This joint venture collaboration embeds essential winning factors including
our excellent natural resources, the best photovoltaic technologies and
diligent, committed partners," said Huadong You, chairman of TZ Group. "Our
four-party, three country landmark partnership sets a role model for the
industry and also embraces challenges for a sustainable future."

"This joint venture is a new milestone in the development of the PV industry
in Hohhot City and the Inner Mongolia Autonomous Region," said Yi Qin, mayor
of Hohhot City. "We look forward to leveraging the strengths of Hohhot City
to support the success of this venture and have full confidence in this
winning collaboration among the four partners."

"We are fully committed to the success of this joint venture and we will meet
the expectations of all levels of government, as well as those of our
partners," said Fusheng Zhang, CEO of IMP. "IMP has an excellent grid
infrastructure, leading experience in grid integration of renewable energy and
strong resources."

The SunPower C7 Tracker combines single-axis tracking technology with rows of
parabolic mirrors, reflecting light onto 22.8 percent efficiency SunPower
Maxeon® cells, the world's most efficient commercially available solar cells.
Using mirrors to reduce the number of solar cells required to generate
electricity lowers the levelized cost of energy by up to 20 percent compared
to competing technologies. For example, a 400-MW C7 power plant requires less
than 70 MW of SunPower solar cells.
