Certified Safety & QA Team
Day & Zimmermann (D&Z) completed our first solar project in 2008 when Mason & Hanger, our architecture and engineering division, designed a 120 KW roof-mounted system for the U.S. Mission to the United Nations in Geneva, Switzerland. In 2021 D&Z made the strategic decision to begin constructing solar as an EPC firm. This has led to our selection as the primary contractor building a total of 200 MW in West Virginia starting in 2023.
Safety is our number one core value. Nothing is more important – not profit, not schedule – nothing. We care about safety because we care about people. For more than a century, we have shared a personal and professional commitment to protect the safety and health of our employees, customers, partners, subcontractors, and the communities we serve. We do this by building strong relationships with our clients, union leadership and our skilled craft employees.

Years of experience
Our leadership knows that in the U.S. and around the world, renewable energy sources will not be the exception but the rule. That’s why we are hiring and empowering project leadership teams with solar and storage experience, investing in capital equipment such as GPS equipped pile drivers, and pursuing acquisitions of companies with resumes in the renewable space. Our goal is to be your preferred solar EPC partner from the first project and strive to continually improve and support your growth.
