CHICAGO — Marist High School has completed a major on-campus solar energy installation, marking a significant milestone in the school’s ongoing commitment to sustainability, environmental stewardship and responsible leadership. The fully installed and operational solar photovoltaic system is located on Marist’s campus at 4200 W. 115th Street in Chicago.
Developed in partnership with Mission Energy and constructed by 93Energy, the project represents a long-term investment in clean, renewable energy and operational efficiency. The system is now actively generating power for the campus, delivering both environmental and financial benefits.
Over 900 solar modules with a total system capacity of approximately 579 kW DC were installed on the 62-year-old building’s roof. The completed solar is expected to generate an estimated 695 kilowatt-hours of electricity and is expected to save $80,000 to $90,000 in annual energy costs annuallyl.
In addition to reducing energy costs, the system is expected to offset approximately 490 metric tons of carbon dioxide each year, an environmental impact equivalent to removing more than 100 gasoline-powered vehicles from the road annually.
“This project reflects Marist High School’s commitment to being thoughtful stewards of our resources and leaders within our community,” David Waterman, director of buildings and grounds for Marist. “The completion of this solar installation allows us to reduce our environmental footprint while providing real-world learning opportunities for our students.”
Beyond its operational impact, the solar installation offers meaningful educational and community value. As a fully functioning system, it serves as a real-world example of renewable energy in action, offering hands-on learning opportunities for students, staff, and visitors while reinforcing sustainability goals across the campus.
