Conducting regular O&M ensures optimal performance of photovoltaic (PV) systems while minimizing the risks of soiling, micro-cracking, internal corrosion, and other problems. Below, you will find several resources that help establish O&M practices. How do I find best practices for. Why Are Specialized Solar Power Plant Operations and Maintenance (O&M) Crucial? Unlike traditional power generation facilities, solar power plants have fewer moving parts, leading some to underestimate the importance of dedicated O&M. National Renewable Energy Laboratory, Sandia National Laboratory, SunSpec Alliance, and the SunShot National Laboratory Multiyear Partnership (SuNLaMP) PV O&M Best Practices. l for the long-term functionality and safety of your solar PV system.
