Educational Benefits: The solar energy systems will serve as a learning laboratory students. Working with City of Palo Alto Utilities and REC Solar, we will have K‐12 supplemental curriculum on the subject of solar energy available for teachers to share with their students.

Student and Staff Comfort Benefits: The solar energy systems will serve as shade structures in parking lots and athletic play fields.
