Scottsdale was among the first school districts in the state to put solar panels on campus roofs, in 2009 at Coronado High School and the Desert Mountain High School/Mountainside Middle School campus.

Since then, panels have been installed at Chaparral, Arcadia and Saguaro high schools, and Copper Ridge School. This summer, panels are being added to Desert Canyon Middle School.

Salt River Project recently donated a small rooftop array to Tavan Elementary School, and that 13.2-kilowatt project just went online last month.
