From the Document: "Field examinations of hurricane-damaged photovoltaic systems have revealed important design, construction, and operational factors that greatly influence a system's survivability from a severe weather event. Recent storms have not only highlighted factors contributing to survivability, but also those leading to failures. These storms also clearly demonstrated the importance of good operational and maintenance practices as a factor in survivability. For existing systems, owners can implement measures (pre- and post-storm) that can greatly minimize equipment damage and recovery time. The U.S. Department of Energy Federal Energy Management Program (FEMP) is expanding its recommended design specifications to include factors and best practices for system survivability identified from recent hurricanes. This fact sheet provides an overview of the upcoming additions to these design specifications. Many of these factors can apply to other severe weather events, such as tornadoes."
