The largest single-roof solar power installation in North America reached completion today at Toyota's North America Parts Center California (NAPCC) in Ontario, California. The 2.3MW project was carried out by SunPower Corporation, and will begin operating in early October.

Covering more than 242,000 square feet of the NAPCC's roof, the project consists of 10,417 SunPower solar modules. Toyota will purchase the generated electricity from GE Energy Financial under the SunPower Access power purchase agreement program, and foresees close to 60 percent of the company’s energy needs being supplied by the project.
