The Mount Diablo Unified School District in California has completed 40 of 51 planned PV installations at district schools and facilities.
When the total number of 51 systems is complete later this year, the systems are expected to reduce the district's electricity costs by more than $3 million per year and save $220 million over the next 30 years. Cumulative capacity will be 12.1 MW.
SunPower is installing the system on rooftops and shade structures in parking lots and hard-court areas. The systems also use SunPower's solar panels, manufactured locally in Milpitas, Calif. All systems are expected to be complete and operational before the end of the year.
The school district's systems were financed through Clean Renewable Energy Bonds secured under the American Recovery and Reinvestment Act of 2009, paid through a local, voter-approved general obligation bond.
