8 Ways To Protect Your Solar Panels from Hail Storm Damage

Solar panels are designed with impressive durability. Even under harsh weather conditions, they typically continue to perform reliably. While hail can strike with great force, most panels can easily endure light to moderate storms. However, during extreme hail events, even the toughest systems may sustain damage.

Fortunately, you’re not defenseless against nature’s elements. With a few proactive steps—such as selecting high-quality panels and adding protective layers—you can protect both your solar energy investment and your savings from hail damage.

Instead of waiting for storms to strike, plan ahead and take preventive measures. This preparation can help you avoid costly repairs or replacements to your solar power system.

8 Ways to Protect Solar Panels From a Hailstorm

The heart of your solar energy setup lies in the photovoltaic (PV) panels. These panels, often mounted on rooftops or in open areas, collect sunlight and convert it into usable electricity. Because they are fully exposed to the elements, it’s natural to wonder whether the glass and materials can handle more than just rain.

Fortunately, most solar panels are built to endure tough weather. Their reinforced glass is designed to resist impact and typically withstands most hailstorms with ease.

Still, extremely severe storms can sometimes exceed these limits. To ensure long-term protection, it’s wise to take preventive steps—starting from your initial purchase decision.

Buy Panels Rated UL 61730 or IP67

The first step to safeguarding your solar system from hail is to choose panels built for durability. The materials used in manufacturing play a key role in determining how well they resist impact.

Modern panels are generally very strong, but those certified under UL 61730 have been tested to withstand hailstones up to 3 inches wide traveling at speeds of up to 88 mph (142 km/h).

Another critical standard is IP67 certification, which ensures resistance to dust and water ingress. Cracked panels caused by hail could lead to leaks, so selecting well-sealed and weather-resistant panels is essential.

OUPES solar panels are IP67 waterproof, making them reliable even under heavy rain, hail, or dust. Their strong build ensures long-term stability and efficient power generation, making them an excellent investment for lasting solar performance.

Use Protective Covers

If a hailstorm is approaching, covering your solar panels can offer added protection. Rigid covers provide maximum defense by absorbing the impact of hailstones and shielding the panels from direct damage.

However, these solid covers block sunlight, meaning you’ll need to remove them after the storm to resume energy production.

Flexible covers offer a lighter level of protection but are much easier to handle. They soften the impact of hail while still being convenient to use. In most cases, a soft cover is sufficient to prevent damage during moderate storms.

Spray on a Methacrylate Layer

Methacrylate is a cost-effective spray coating that adds a transparent protective layer to your panels without blocking sunlight. It’s a practical solution for those who want protection without sacrificing performance.

When applying it, ensure you use the correct amount. Overapplication can interfere with energy absorption. Avoid spraying on metal components to prevent electrical issues.

Test a small section first to determine the ideal thickness. Properly applied, methacrylate offers affordable and efficient protection against minor hail impacts.

Protect the Panels with Wire Mesh

Installing a wire mesh barrier over your panels provides a simple yet effective defense against hail. It prevents direct strikes while still allowing sunlight to pass through.

The mesh openings should be large enough for light but small enough to block hailstones. Secure installation is crucial—if the mesh is loose, strong winds could dislodge it and expose the panels.

When properly fixed, wire mesh offers a budget-friendly and reliable option for protecting your solar panels without hindering their efficiency.

Adjust the Angles of Your Panels

Proper panel angle adjustment is not just about optimizing sunlight—it can also help protect against hail. Panels installed at steeper angles are less likely to receive direct impacts from falling hailstones.

OUPES 240W portable solar panel is a perfect example. Its adjustable stand lets you easily modify the panel’s angle for maximum energy absorption—up to 22% efficiency—while reducing exposure to hail. When storms are forecasted, you can simply fold and store the panels indoors to keep them safe.

Inspect Your Panels Regularly

Just as small cracks in a windshield can grow into serious fractures, minor damage on solar panels can worsen during storms. Regular inspections allow you to detect and fix issues early before they become expensive problems.

Flexible panels tend to resist impact well, but rooftop systems using rigid glass panels are more vulnerable. Even tiny cracks can reduce efficiency and increase risk during hailstorms.

Perform visual inspections regularly, and schedule professional maintenance when needed to ensure long-term reliability.

Check Your Homeowner’s Insurance Policy

While most solar panels include manufacturer warranties, these typically exclude weather-related damage like hail. To ensure coverage, review your homeowner’s insurance policy carefully.

In many cases, hail damage can be claimed through standard home insurance. If your rooftop system suffers damage, filing a claim through your insurer is often the best course of action.

Follow the Weather Forecast

Preparation also means staying informed. By monitoring weather forecasts, you can take timely action—like covering or removing portable panels—before a storm arrives.

Severe weather patterns can shift quickly, so paying attention to alerts gives you valuable time to protect your investment. Proper preparation ensures your panels survive most storms with minimal or no damage.

FAQs

Can Solar Panels Withstand a Hailstorm?

Yes, most modern solar panels are built to endure hailstorms. However, in areas where hail is particularly large or frequent, damage can still occur. Choosing durable, certified panels significantly reduces this risk.

Do Solar Panels Work if Cracked?

Solar panels can still function with small cracks, but their efficiency decreases over time. Larger cracks can lead to reduced performance and possible electrical issues, so prompt repair or replacement is advised.

How Much Damage Does Hail Cause to Solar Panels?

Minor hail usually causes little to no damage. However, larger hailstones can chip, crack, or even break panels during severe storms, especially if the panels are older or poorly installed.

Can You Fix Hail Damage to Solar Panels?

Yes, hail-damaged panels can often be repaired. Professional technicians can replace broken glass or damaged components, restoring your system’s performance and extending its lifespan.

Can You Claim Insurance If Your Solar Panels Are Damaged By Hail?

While solar warranties rarely cover hail damage, most homeowner’s insurance policies do. As long as your panels are included in your policy, you should be eligible for coverage in the event of hail damage.

Conclusion

In most hailstorms, your solar panels will remain intact thanks to their strong construction. Only in the rarest, most intense storms does damage become likely. Still, it’s best to prepare ahead of time.

Protection starts with quality materials. OUPES solar generator kits and high-efficiency solar panels are engineered to withstand extreme weather and temperatures—ensuring your power system stays reliable, rain or shine.
