On stormy evenings, homeowners wonder: can solar panels withstand hail, or will jagged ice ruin a brand-new array? Accordingly, modern modules pass rigorous impact tests and shrug off most Atlantic squalls.
Hail Testing 101—Why Tempered Glass Wins
International standard IEC 61215 launches 25 mm (1 in) ice balls at 23 m/s against eleven points on a panel. Tier-1 modules—including our JA Solar JAM54D41-440/LB (22 % efficiency, 5 400 Pa snow-load, 225 km/h wind rating)—sail through without cracking.
Moreover, independent labs such as PV Evolution Labs have repeated the test with 35 mm hail at even higher speeds and still report minimal breakage in premium designs, adding an extra margin of safety.
Real-World Proof from Research & Halifax Roofs
NREL’s fleet study notes that hail under the 25 mm threshold rarely dents production, and installation quality matters as much as ice size.
Likewise, a 2024 Halifax storm pelted one client’s 16-panel array; a next-day inspection found zero damage—tempered glass dispersed each impact like a car windshield.
Extra Layers of Protection
Consequently, you can stack the odds even further:

Peace of mind for extreme-weather worriers |
Remember, panels are typically included under standard homeowner policies; confirm deductibles before storms roll in.
Post-Storm Checklist—Safety First
After hail, glance at your monitoring app. If output looks normal, relax. Otherwise, a quick binocular scan from ground level is enough; if you spot spider-web glass, contact Atlantic Solar support for a pro assessment. Please skip the ladder—warranties stay intact only when certified techs handle replacements.
