Solar panels are engineered and tested to withstand significant hail impact, making severe hail damage relatively rare — but it’s not impossible under extreme conditions. Panels are certified to IEC hail impact standards, and most damage that does occur is covered under manufacturer warranty or homeowners insurance.
IEC Hail Rating Standards
| Standard | Test Conditions |
|---|---|
| IEC 61215 | 25mm (1 inch) ice balls at 23 m/s (about 82 km/h) |
| Enhanced hail testing (some manufacturers) | Larger hail sizes tested for premium product lines |
What the Standard Certification Covers
Standard IEC 61215 certification requires panels to withstand 1-inch diameter ice balls impacting at roughly 82 km/h without failure — this covers the vast majority of hail events, since most hailstorms produce hail smaller than golf-ball size (about 1.75 inches).
Real-World Damage Data
Insurance and industry data suggest severe hail damage to solar panels is relatively uncommon given standard certification requirements, though large hail events (baseball-sized or larger) can occasionally cause cracking or complete panel failure beyond what standard testing anticipates.
Insurance Coverage for Hail Damage
Most homeowners insurance policies that cover roof hail damage also extend to solar panels mounted on the roof, though specific coverage terms vary by policy and insurer — confirming your specific coverage with your insurance provider is worthwhile after installation.
Protection Options in High-Risk Hail Areas
In regions with frequent severe hail (parts of the Great Plains, for example), some installers offer enhanced hail-rated panels, and homeowners can verify their specific policy’s coverage terms — though standard panels already provide substantial protection for the vast majority of hail events nationwide.

Frequently Asked Questions
Can solar panels be damaged by hail?
It’s possible, but rare — panels are certified to withstand 1-inch hail at high speed, covering most real-world hailstorms.
What is the IEC hail rating standard for solar panels?
IEC 61215 requires panels to withstand 25mm (1-inch) ice balls at roughly 82 km/h without failure.
Does insurance cover hail damage to solar panels?
Most homeowners policies covering roof hail damage also extend to solar panels, though terms vary by insurer.
Can very large hail still damage certified panels?
Yes — baseball-sized or larger hail can occasionally exceed standard testing thresholds and cause damage.
Are there hail-resistant solar panels for high-risk areas?
Some manufacturers offer enhanced hail-rated panels for regions with frequent severe hailstorms.
How common is hail damage to solar panels?
Relatively uncommon, given that standard certification covers the vast majority of hail events.
Should I get extra insurance for solar panels in hail-prone areas?
It’s worth confirming your specific coverage terms with your insurer, especially in high hail-risk regions.
