Customer ServiceThe greatest contributor to insured losses on solar PV systems worldwide is severe hail. Severe hail events are forecasted to increase in frequency over time, emphasizing the increasing importance of designing and preparing for solar PV resilience to hail. Many areas are prone to hail events, and the level of risk a site faces may not be intuitive.
In particular, hail damage seriously affects photovoltaic systems. The severity of hailstorms as well as impact responses are important factors in mitigating loss, so the first research area that needs to be addressed is the resistance of photovoltaic modules to hail.
Hail, as solid ice, poses a greater threat than snow due to its potential for physical damage or reduced efficiency. The rate at which hailstones fall during hailstorms heightens the risk of solar panel damage. Despite technological advances in hail-resistant panels, it is best to stay cautious and use covers for additional protection.
Protecting solar panels from hail requires an automated solar panel angle system to provide continuous sunlight access in bad weather. Use a remote to adjust the surface exposure by changing the angle. Monitor the weather forecast for optimal panel protection in changing conditions. 6. Stay Informed with Weather Predictions
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. Some measures can be taken to limit damage to PV modules.
Solar assets located in hail-prone regions face higher risks of damage over their 25+ year lifespan. The American Meteorological Society analyzed hail patterns across the United States from 2009 to 2018 to quantify high-exposure areas. Colorado, Nebraska, and Wyoming ranked as the top three states for hailstorm frequency and severity.
