Solar panels are rated to handle 1 inch hail at 52mph (IEC 61215). Damaged panels can be easily replaced, and are typically covered by your homeowner's insurance.
- Every panel sold in the U.S. has to pass an industry-standard hail test, which fires ice balls at multiple points on the panel and requires no visible cracking, delamination, or more than a 5% drop in power output afterward. Companies like UL Solutions, an applied safety science company, test solar panels by dropping a two-inch solid steel sphere from 51 inches onto panels, simulating the impact energy of serious hail. Panels that survive without electrical hazards earn certification for real-world deployment.
- The proof is in the pudding—or in this case, the parking lot. When a severe hailstorm hammered the National Laboratory of the Rockies' (NLR) (formerly National Renewable Energy Laboratory (NREL)) Colorado campus in 2017, just one single panel out of more than 3,000 suffered damage. That's a 99.97% survival rate against Mother Nature.
