The San Diego Jewish Academy has begun construction of a 800 kilowatt solar project on its campus.

The school says on its website that it expects to save $400,000 a year by generating its own electricity instead of buying power from the local utility.

The solar panels will be installed on most of the school’s rooftops, as well as on carports in the school’s parking lots. The system is scheduled to be completed in March.

School officials say the installation will help the academy become an entirely energy self-sufficient campus.

“While some college campuses have achieved this, we are not aware of any independent school in the U.S. that has,” the school’s blog says.
