This study examines the effects of hailstorms on photovoltaic (PV) modules, focussing on damage mechanisms, testing standards, numerical simulations, damage detection techniques, and mitigation strategies. A comprehensive review of the recent literature (2017–2025), experimental results, and case. . Historically, solar photovoltaic PV modules have survived the majority of hail events they have experienced. In areas that have experienced very large hail (greater than 1 ¾" or 44 mm diameter), however, hail has caused significant damage to PV modules. Although single-axis tracker stow-mode approaches have sought to make solar power. . The International Electrotechnical Commission (IEC) 61215, the industry's long-accepted hailstone impact test, provides an example of the challenges posed by growth markets in severe storm-prone regions. This baseline test established a minimal hail impact rating from hailstones up to 1 inch in. .
