In this episode of Sean White’s Solar and Energy Storage Podcast, host Sean White sits down with Michael Schwarz, General Manager of Growth at Arch O&M, to discuss the critical but often overlooked role of operations and maintenance (O&M) in the solar industry. Recorded at Intersolar San Diego, the conversation provides a behind-the-scenes look at what it takes to keep commercial and utility-scale solar systems operating efficiently throughout their lifespan.
Schwarz describes O&M as the “service department” of the solar industry, responsible for ensuring that photovoltaic systems continue producing energy safely and reliably long after installation. He explains that Arch O&M primarily serves commercial, industrial, and ground-mounted solar projects ranging from approximately 400 kW to 20 MW. While solar systems are known for their durability, many begin requiring more extensive maintenance after seven to nine years of operation, making proactive service essential for maximizing performance and return on investment.
The discussion covers a variety of maintenance practices, including IV curve testing, drone inspections, insulation resistance testing, troubleshooting, and performance monitoring. Schwarz highlights the growing importance of storm and weather-related remediation, noting that wind, hail, and other severe weather events are creating increased demand for specialized repair services. He also discusses the challenge of sourcing replacement modules for older systems when original equipment is no longer available, a common issue as the solar industry matures.
A significant portion of the conversation focuses on workforce development and training. Schwarz emphasizes Arch’s commitment to developing skilled technicians and supporting professional certifications through NABCEP, including the PV Commissioning and Maintenance Specialist credential and the emerging O&M Associate Technician pathway. He and White discuss the value of continuing education and industry events such as the NABCEP Conference in Milwaukee.
Overall, the episode highlights how effective operations and maintenance programs protect solar investments, improve system performance, and support the long-term growth and professionalism of the renewable energy industry.
