Hail is a form of precipitation that can range in size from small pellets to large stones, and it can cause significant damage to solar panels if not properly protected. It’s important to understand how hail can impact solar panels to take the necessary steps to safeguard them.

What is Hail?

Hail is a type of solid precipitation that forms in thunderstorms. Strong winds push raindrops up into very cold areas of the atmosphere where they freeze into ice balls. These can grow larger as more water freezes on them.

Then, they fall to the ground when they become too heavy for the clouds to hold. Hail stones vary in size, sometimes as small as peas or as big as baseballs.

Hail can be tough on things it hits, including solar panels. Small hail usually isn’t a problem for solar panels because they are built to handle these impacts. But large hail stones over 2 inches in diameter have enough force to damage the panels’ surface, which might chip, crack or break them open.

This kind of damage can make a solar panel less effective at turning sunlight into electricity and may lead to costly repairs or replacements if severe enough.

How Hail Can Damage Solar Panels?

Now that we understand what hail is, let’s look at its impact on solar panels. Strong hail storms throw ice balls from the sky that can hit solar arrays with a lot of force. This can lead to serious trouble for your solar cells.

The hard ice can chip or crack the tempered glass that protects them. Even if you don’t see any cracks, small ones could be hiding and may cause big problems later.

These hits from hail can also hurt how well your solar panels work and last over time. If the strikes are powerful enough, they might break open the panels completely. Smaller hailstones might not shatter the glass but can still damage the cells inside without being seen right away.

This kind of harm means your panels won’t make electricity as well as before and could make them die sooner than they should.
