Toyota and SunPower Complete Largest Single-Roof Solar Installation in North America

Toyota and SunPower Complete Largest Single-Roof Solar Installation in North
America

ONTARIO, Calif. and SAN JOSE, Calif., Sept. 24 /PRNewswire-FirstCall/ --
Toyota and SunPower Corporation (Nasdaq: SPWR), a manufacturer of
high-efficiency solar cells, solar panels and solar systems, today announced
the completion of the largest single-roof solar power installation in North
America. The 2.3-megawatt SunPower system will begin operation in early
October at Toyota's North America Parts Center California (NAPCC) in Ontario,
Calif.
Toyota expects the solar installation will provide nearly 60 percent of
the total electricity needs for the 760,000-square foot NAPCC. The system
covers more than 242,000 square feet of the NAPCC's roof and includes 10,417
solar modules, enough to cover more than four football fields. It is expected
to avoid about 6.4 million pounds of carbon dioxide emissions annually, which
is the equivalent to the emissions from the energy use of approximately 255
homes in a year.
"Toyota's Earth Charter challenges the company to pursue all possible
environmental technologies in the pursuit of sustainable mobility," said Jim
Lentz, president of Toyota Motor Sales, U.S.A., Inc. "That extends the
company's environmental responsibilities beyond products to include our
manufacturing plants and other facilities where sustainable and renewable
energy sources such as solar power are increasingly important."
"Toyota is a global business leader in environmental sustainability," said
Tom Werner, chief executive officer of SunPower. "The solar power generated by
this system will reduce Toyota's operational costs at the Ontario facility
immediately and over the long term, as electric utility rates continue to
increase. Toyota understands that solar is affordable today as a means to
improve the quality of our environment and promote local, clean, reliable
power."
SunPower installed SunPower(R) T10 Solar Roof Tiles at the Toyota
facility, equipped with SunPower solar panels, the most efficient solar panels
available on the market today. T10 Solar Roof Tiles are non-roof penetrating
and tilt at a 10-degree angle to increase energy capture.
Toyota will purchase the electricity generated from the system from GE
Energy Financial under the SunPower Access(TM) power purchase agreement (PPA)
program. GE Energy Financial will finance, own and operate solar power
systems, providing Toyota with immediate savings and a long-term hedge against
rising peak power prices. Toyota owns the renewable energy credits associated
with the system.
The NAPCC is not Toyota's first foray into solar power. The company's
South Campus headquarters building in Torrance, Calif., featured one of the
largest privately funded systems of its kind when it opened in 2003. Also
built by SunPower, the system covers 53,000 square feet of rooftop.
