ONTARIO, Calif. - SunPower Corp., a manufacturer of solar cells, panels, and systems, has announced the completion of the largest single-roof solar power installation in North America - a 2.3-megawatt system 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.”

Toyota will purchase the electricity generated from the system from GE Energy Financial under the SunPower Access™ power purchase agreement (PPA) program. GE Energy Financial will finance, own, and operate the solar power system, 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.
