The report identifies critical failure modes in ground-mount solar PV systems exposed to extreme winds, such as the failure of top-down clamps and low-cycle fatigue in module frames. It recommends high-load modules (4,000 Pa uplift), through-bolting with specialized washers, and dual-post foundation designs to improve survivability in hurricane-prone regions.

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.

This report provides a technical assessment of the boiler plant and associated systems at Hendrina Power Station, focusing on life extension (Life-ex) studies for Units 1-10. It details boiler tube leak (BTL) patterns, component replacement histories, and the degradation of pressure parts, specifically highlighting issues with fly-ash erosion, sootblower erosion, and creep exhaustion in main steam piping.
