The agreement is expected to save the district $192m over the 30-year life of the systems.

The solar systems by SunPower, to be completed in phases through early 2012, will be shade structures installed in school parking lots and hard court areas.

The systems will be financed through Clean Renewable Energy Bonds (CREBs) secured by the district under the American Recovery and Reinvestment Act of 2009 with an interest rate of 1.75 paid by the federal government.

SunPower residential and commercial business group president Jim Pape said that the Mount Diablo Unified School District is capturing an good opportunity to reduce its utility costs while helping the state meet its renewable energy goals.

"SunPower’s technology, experience will serve to ensure Mount Diablo Unified achieves impressive long term savings," Pape said.
