SOLAR UNDER STORM
The report analyzes the failure and survival of solar PV systems during Hurricanes Irma and Maria in the Caribbean to establish design and specification standards for high-wind environments. It identifies root causes of failure—such as undersized racking, inadequate bolting, and the use of T-clamps—and recommends high-load modules, through-bolting, and dual-post foundations. The authors advise against using trackers in Category 4 or higher wind zones and emphasize the need for site-specific structural engineering and collaboration between stakeholders and suppliers to develop Category 5-resistant hardware.
