With the increasing popularity of solar panel installations, a common concern among homeowners is their durability and ability to withstand severe weather conditions. One of the most frequent questions asked is, “Can solar panels withstand hail?”
In this article, we will discuss the truth behind hail damage and the measures that solar panel manufacturers and installers take to ensure the durability of these systems.
The Myths and Truths of Solar Panel Hail Damage
Solar panels are made of tempered glass, a highly durable material that withstands wind, rain, and snow. However, many people worry about the impact of hail on their solar panels.
First, let’s dispel a common myth: solar panels are not fragile and do not shatter easily under hail. In fact, the glass used in solar panels undergoes rigorous testing to ensure its ability to withstand hail impact.
Although, it is true that large hailstones will damage to solar panels. It’s important to understand that hailstones this large are rare. The majority of hailstones that hit solar panels are small in size and unlikely to cause harm.
Also, even if a hailstone does crack a solar panel, the damage is often localized and does not affect the overall performance of the system. Read what the Department of Energy has to say about hail storms and solar panels.

The Protective Measures: How Solar Panel Manufacturers Ensure Durability
To ensure the durability of solar panels, manufacturers implement several protective measures:
Tempering Glass: Solar panel glass is tempered or reinforced during the manufacturing process. This involves heating the glass to a high temperature, then rapidly cooling it. This process creates a strong outer surface capable of withstanding impacts and extremes in temperature.
Testing: Moreover, solar panels undergo rigorous testing for durability and performance. These tests include hail and impact resistance tests that simulate real-world hailstones and other potential hazards. Learn 4 ways to test your solar panels yourself.
Quality Materials: Equally important, solar panel manufacturers use high-quality materials designed to withstand weather extremes. They often incorporate protective layers and coatings to reduce the risk of damage from environmental factors.
Warranty Protection: Additionally, most solar panel manufacturers offer warranty protection against hail damage, giving you the peace of mind and assurance that your investment is protected.

The Installation Process: Ensuring Optimal Performance and Protection
Solar panel installers play a critical role in installing solar panels to maximize durability. Here are some ways they help to protect solar panels during installation:
Racking Systems: First, they mount solar panels on racking systems designed to withstand extreme weather conditions. The racking systems use heavy-duty materials that can support the weight of the panels and can keep them in place during hailstorms.
Proper Pitch: Second, during installation, solar panels get pitched properly to prevent standing water and ice buildup, which adds weight and stress to the panels during hailstorms.
Secure Attachment: Third, solar panel installers use proper attachment methods, such as bolts, screws, and compression fittings, to make sure the panels stay securely fastened to the racking systems.
Inspection and Maintenance: Fourth, regular inspection and maintenance by a professional installer helps to identify any issues before they become major problems. This includes checking for any cracks or damages that affect the panel’s performance.
Wrapping up, the truth is that solar panels are highly durable and will not typically incur damage from hail. While larger hailstones do cause damage, they are rare occurrences.
Again, the tempered glass in solar panels is strong enough to handle hail. What’s more, scheduling a solar panels installation is a great time to also replace a roof. Take a look at our roof replacement service page for more information.
The protective measures taken by solar panel manufacturers and installers guarantees the durability and longevity of these systems.
Finally, as a homeowner, investing in a solar panel installation is a wise choice, providing you with a reliable and sustainable energy source.
