Solar Panels & Hail: How Much Hail Can Solar Panels Handle?

Blog Updated: July 2023

With hail as a frequent concern here in Colorado’s Front Range, our customers often ask us how concerned they should be about solar panel hail damage and if their new solar energy system will hold up against extreme weather over its 25-plus year lifespan.

Today’s solar panels are designed to withstand even the harshest of outdoor elements. Whether you are considering a rooftop system for your home or a roof or ground-mounted solar array for your commercial property, you can rest assured that your solar PV system will continue to convert clean, renewable solar energy into electricity for decades.

Solar Panel Resilience Against Extreme Weather Conditions

The solar industry’s top solar panel manufacturers have long understood the need for solar panels that can withstand extreme weather conditions like high winds and hail. In fact, most manufacturers test and certify their solar panels to withstand hail up to one inch in diameter falling at 50 miles per hour.

Today’s solar panels are also extremely resilient against high winds and heavy rain. Most solar panels are certified to withstand hurricane force winds. In addition, the aluminum and glass casings that hold a solar panel’s solar cells are highly waterproof, even during extreme rain.

How 3,000 Solar Panels Measured Up Against a Massive Hail Storm

The National Renewable Energy Lab (NREL) in Golden, Colorado, can attest to the resilience of solar panels against extreme weather. NREL is home to an enormous solar energy system consisting of 3,168 rooftop- and ground-mounted solar panels. In 2017, a severe hail storm hit the greater Denver area and the NREL campus.

Despite hailstones up to 2.75 inches in diameter being reported in the area — and the countless cars and windows that were damaged — only one of the facility’s 3,168 solar panels sustained damage. That’s a major testament to the resilience of solar panel systems.
