Are there specific regions where solar panels are more prone to hail damage?
April 5, 2026
Quick Answer
Solar panels are more prone to hail damage in regions with high-frequency hail storms, typically occurring in areas with severe thunderstorms, such as the Great Plains in the United States, the Canadian Prairies, and parts of Australia.
Hail Storm Hotspots
The risk of hail damage to solar panels is highest in regions with frequent hail storms. According to data from the National Oceanic and Atmospheric Administration (NOAA), the top 10 hail-prone counties in the United States include Cheyenne County, Kansas; Phillips County, Colorado; and Morton County, Kansas, all of which have experienced hail storms with diameters of 1 inch or larger.
Hail Damage Mitigation Techniques
To mitigate hail damage, solar panel manufacturers often use hail-resistant materials, such as tempered glass or polycarbonate panels. These materials can withstand hail impacts of up to 1 inch in diameter and reduce the risk of damage. Homeowners can also install hail-resistant solar panels with a hail impact rating of 1 inch in diameter at 50 mph, which is equivalent to a 1-inch hail storm with winds of 50 mph.
Hail-Resistant Solar Panel Standards
The International Electrotechnical Commission (IEC) has established standards for hail-resistant solar panels, including IEC 61701, which specifies the requirements for testing and evaluation of the resistance of photovoltaic modules to hail impact. Solar panel manufacturers that comply with these standards can provide homeowners with assurance that their panels are designed to withstand hail storms and minimize the risk of damage.
