Photovoltaic panels can withstand hail, but there are some considerations:Solar panels are built to handle hail up to 25mm, similar to car glass.Sometimes they encounter hail over 100mm, which can be a challenge.Hail can cause invisible damage through solar cell cracking at smaller diameters and speeds12..
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!.
Hail can cause invisible damage through solar cell cracking at hail diameters and speeds less than that which would break the glass. [pdf]
