Climate Change Escalates Hailstorm Threat to Solar Plants, Urges Resilience Measures – BNN Breaking

2 minutes, 22 seconds Read

Amid the escalating climate crisis, solar power facilities face an increased threat from severe hailstorms, prompting an urgent call for enhanced protective measures. According to recent studies by PV Evolution Labs (PVEL) and other testing services, the phenomenon of larger and more destructive hail, driven by global warming, is set to compound the challenges for the solar energy sector. This development underscores the necessity for solar projects to adopt advanced resilience strategies against hail damage to safeguard infrastructure and ensure operational continuity.


Understanding Hail Impact on Solar PV Plants

The severity of hailstorm impacts on solar power installations varies, influenced by factors such as hail size, density, and the angle of impact. PVEL’s research highlights that smaller, denser hail can be more destructive than its larger counterparts, inflicting significant damage on solar modules. The orientation of solar panels also plays a critical role in mitigating hail damage, with angled panels faring better than those mounted horizontally. To assess the durability of PV modules against hail, PVEL has developed the Hail Stress Sequence, a stringent testing protocol that simulates the kinetic energy of hail impact, offering insights into the resilience of different solar module designs.

Innovations in Hail Damage Mitigation


The solar industry is responding to the hail threat with innovative testing and design strategies aimed at enhancing module resilience. Beyond the standard qualification tests, companies like the Renewable Energy Test Center (RETC) are advancing hail durability testing to reflect real-world conditions more accurately. These efforts are critical in identifying modules that can withstand the increased hail risks posed by climate change. Furthermore, solar developers are exploring smart operational practices, such as the deployment of hail stow strategies, which adjust the tilt of solar trackers to minimize damage during hailstorms.

Insurance and Risk Management in the Age of Climate Change

The rising frequency and intensity of hailstorms necessitate a reevaluation of risk management and insurance strategies for solar projects. Innovative approaches to insuring solar assets, including data-driven assessments of hail resilience and proactive mitigation measures, are becoming increasingly important. Companies like kWh Analytics are at the forefront of developing tools that enable solar developers to make informed decisions about equipment specifications and operational practices, thereby reducing vulnerability to hail damage. These advancements underscore the importance of comprehensive risk management strategies in the face of climate change-induced weather extremes.

The escalating threat of hail damage to solar power plants, exacerbated by climate change, highlights the urgent need for the industry to adopt more resilient designs and operational practices. As solar energy continues to play a crucial role in the global transition to renewable sources, ensuring the durability and reliability of solar infrastructure against extreme weather events will be paramount. The collaboration between testing labs, manufacturers, and developers in advancing hail resilience is a positive step forward, but ongoing innovation and adaptation will be essential in safeguarding the future of solar energy.
