New hail test aims to more accurately measure solar panel resilience
Research from Central Michigan University found that almost all (99.3%) of solar plants in the U.S. have at least a 10% chance of having hail of 2 inches near the project each year. Over a 25

Commercial Solar Photovoltaics (PV) Wind and Hail Risk
Solar PV Panel Hail Impact Resistance: At the very least, solar PV panels should meet the IEC 61215 standard for hailstone impact resistance (1-inch diameter). However, PV farms in regions with the
-
Does Hail Damage Solar Panels? Complete 2025 Protection Guide
Research confirms that front glass panels with the standard thickness of 3.2 mm could not withstand the impact of larger hailstones, while 4-mm-thick panels successfully reduced or nullified

Solar Panels & Hail Resistance: What Real-World Tests Reveal
Solar panels are tested for hail resistance using IEC 61215 and ASTM E1038 standards. These tests involve hitting panels with ice balls of about an inch in diameter at speeds around 51
