Hail consists of solid ice, which falls from the sky like rain or snow. Hailstones are created when moisture is quickly pushed upwards in the clouds during an updraft. These conditions bring hot and cold temperatures together. As a result, the tiny water droplets freeze and form round, solid hailstones. Heavy thunderstorms. Here's a fact: solar panels are built to handle hail up to 25mm, just like the glass on your car. They're tough, but sometimes they see a hail of over 100mm — that's huge!.

Although hail damaging your solar panels is unlikely, the roof surrounding the array could still incur damage..
Solar panels are known for their durability and ability to withstand various weather conditions. Although hail is a common concern, it is generally not damaging. [pdf]

Luckily, robust protective measures like specially engineered glass, panel tilt orientation, raised panel mounting, and hail guards can mitigate most hail damage..
Luckily, robust protective measures like specially engineered glass, panel tilt orientation, raised panel mounting, and hail guards can mitigate most hail damage..
Solar panels, with thick tempered glass, can endure hail diameters from 1 to 1.75 inches, propelled at speeds of 25 to 40 mph, and typically withstand severe hailstorms..
Historically, solar photovoltaic PV modules have survived the majority of hail events they have experienced..
According to IEC 61215 standard, a PV module should resist at the minimum to the impact of a hailstone of 25 mm launched at 80 km/h, while the Swiss VKF standard demands a minimum of 30 mm, practic. [pdf]
